Performance Management in the Oncology Hospital: From KPI to Management Decision (Introduction 101)

Prof. Dr. Mehmet Nurullah Kurutkan, Düzce University, Faculty of Business, Department of Health Management

Abstract. This chapter introduces, at beginner level, time to treatment initiation, multidisciplinary tumour board (MDT) coverage, radiotherapy waiting time, and capacity and quality indicators for physicians who manage or are preparing to manage an oncology hospital, and ties these indicators to management decisions through the chain of target, threshold, variance and managerial intervention. The core message is that an indicator is an examination finding, variance analysis is a differential diagnosis, and a managerial intervention is a treatment. The chapter contains current evidence selected from seven Web of Science searches, a worked case and a pocket card for physicians.

Key concepts: key performance indicator, time to treatment initiation, MDT coverage, radiotherapy waiting time, capacity utilization, statistical process control, variance analysis, patient navigation

Chapter plan and reading guide

This chapter covers four core indicator families in an oncology hospital (time to treatment initiation, multidisciplinary tumour board coverage, radiotherapy waiting time, and capacity and quality indicators) and the chain of “target, threshold, variance, intervention” that ties them to management decisions. It moves from simple to complex: first the concepts, then the indicators one by one, then how to read a variance and choose an intervention, and finally a worked case and a pocket card for physicians.

How to read it. A reader in a hurry can build the framework from Sections 2, 9 and 13. A manager working on a specific indicator can go straight to the relevant section (4, 5, 6, 7 or 8). For a participant preparing for the workshop, Sections 10 and 11 should be read together.

Note on sources. The chapter was written by selecting the directly relevant studies from the corpus obtained in seven separate Web of Science (WoS) searches (time to treatment initiation, waiting times, MDT coverage, oncology quality indicators, oncology capacity indicators, control charts and variance analysis). A few classic works from the quality management literature were added for the conceptual foundation. The figures given in the text belong to the context of the study concerned; they should not be carried over unchanged to another hospital but read as pointers.

1. Introduction: the clock is also a clinical finding

In oncology, time is a finding that describes the workings of the institution as much as the biology of the tumour. The number of days in which a patient gets from diagnosis to treatment tells us about both the course of the disease and the hospital’s appointment, diagnostic, tumour board and treatment capacity. The first task of the oncology hospital manager is therefore to learn to read the clock like a clinical finding.

The evidence shows that delay has a real price in some cancers. In a meta-analysis in colorectal cancer, treatment delay was associated with an increase in all-cause mortality, with hazard ratios (HR) of 1.12 at 4 weeks, 1.24 at 8 weeks and 1.39 at 12 weeks (Ungvari et al., 2025). A similar meta-analysis in breast cancer reported that the HR for breast cancer-specific death rose to 1.20, 1.43 and 1.71 at 4, 8 and 12 weeks respectively (Ungvari, Fekete, Buda, Lehoczki, Munkácsy, et al., 2026). A microsimulation for Canada projected that disruptions to diagnosis and treatment during the pandemic could lead to about 21,247 (2.0%) additional cancer deaths between 2020 and 2030 (Malagón et al., 2022).

The picture is not the same in every cancer, however. In lung cancer, short delays of 4 to 12 weeks showed no significant relationship with survival (Ungvari, Fekete, Buda, Lehoczki, Fekete, et al., 2026). There are even findings in which patients with advanced non-small cell lung cancer who waited longer had a lower risk of death, as if “waiting were good for them” (Klarenbeek et al., 2023). The reason is that sicker patients are treated faster anyway; this is known in the literature as the waiting time paradox (Tope et al., 2025). The lesson for the physician is clear: time is an important indicator, but it is never read alone; it is interpreted together with tumour type, stage and treatment pathway.

The starting point of this chapter is the case used in Module II of the Oncology Hospitals Executive Development Programme. In the case, one of the hospital’s strategic goals is to reduce the time from diagnosis to the start of treatment. Over the last three months, however, this time has lengthened, radiotherapy waiting time has risen, the rate at which MDT decisions are implemented on time has fallen, and capacity in some branches has begun to be under-used. The surgical, medical oncology and radiation oncology teams disagree about the source of the problem, and patient complaints are increasing. This chapter offers the tools needed to read such a picture and derive a management decision from it.

After reading this chapter, the reader is expected to be able to:

  • Distinguish the concepts of indicator, KPI, target, threshold and variance.
  • Define time to treatment initiation, MDT coverage and radiotherapy waiting time correctly and read them by splitting them into parts.
  • Use capacity and quality indicators together with time indicators in a balanced dashboard.
  • Use control chart logic to tell whether a variance is real or random.
  • Choose an evidence-based managerial intervention matched to the root cause of the variance and set up a monitoring plan.

2. Core concepts: a glossary from indicator to decision

Performance management is the institution-level counterpart of the clinical reasoning a physician uses every day. An indicator is what an examination finding is; variance analysis is what a differential diagnosis is; a managerial intervention is what a treatment is; monitoring is what a follow-up visit is. This similarity helps physicians see performance management not as a “foreign language” but as the application of a familiar logic to a new field.

ConceptShort definitionIn the physician’s languageOncology example
IndicatorA measure that expresses the state of a process or an outcome as a numberVital signNumber of days from diagnosis to treatment
Key performance indicator (KPI)One of a small number of critical indicators tied directly to a strategic goalA parameter monitored continuously in intensive careShare of new patients starting treatment within 30 days
TargetThe level to be reachedTarget HbA1c or target blood pressure“At least 80% of new patients start treatment within 30 days” (example)
ThresholdThe limit beyond which action is requiredCritical value notificationIf the rate falls below 70%, a root cause review begins (example)
Tolerance bandThe range within which natural fluctuation is acceptedReference rangeUps and downs of a few days from week to week
Variance (deviation)The difference between the actual value and the targetDeparture from the expected clinical courseMedian time 9 days longer than the target
Common-cause variationEver-present fluctuation arising from the structure of the system itselfPhysiological variabilitySeasonal patient volume
Special-cause variationA signal from outside the system, arising from a specific eventA newly developed complicationA one-week backlog after a LINAC breakdown
Root causeThe underlying mechanism producing the varianceAetiologyNobody being responsible for the appointment after the MDT
Managerial interventionA change designed to address the root causeTreatmentAssigning a patient navigator
Balancing measureAn indicator that monitors whether the intervention causes harm elsewhereMonitoring for side effectsTracking guideline adherence while time is shortened

There is an order among these concepts. First indicators are defined; then a few that connect to strategy are chosen as KPIs. A target and a threshold are set for each KPI. When the actual value departs from the target, a variance arises. The manager first decides whether this variance is common cause or special cause, then finds the root cause and chooses a matching intervention. Finally the effect and the side effects of the intervention are monitored. The distinction between structure, process and outcome made by Donabedian (1988), one of the founders of quality management, forms the background of this chain: structure (people, machines, beds) shapes process (appointments, tumour board, treatment), and process affects outcome (survival, quality of life, experience).

Figure 1 shows the cycle that forms the backbone of this chapter. The cycle works with the same logic as the physician’s sequence of “finding, differential diagnosis, treatment, follow-up”.

3. Choosing indicators: what do we measure, and why?

A good dashboard consists of a small number of well-defined indicators for which data can actually be collected. The oncology literature has no shortage of indicators; the problem is choosing. From 15 quality indicator frameworks used for breast and colorectal cancer in the G7 countries, a total of 512 indicators were extracted, the great majority of which were process indicators derived from clinical guidelines (T. Nash et al., 2026). In a Delphi study for thoracic oncology in Australia and New Zealand, 422 international indicators were screened, 71 were assessed and consensus was reached on only 27 (J. Nash et al., 2024). These proportions tell the manager something: the task is not to measure everything that can be measured but to choose what will produce decisions.

Three questions guide the choice:

  1. Which strategic goal does this indicator serve? For an indicator to be a KPI it has to be tied to a goal. For the goal “shorten the time from diagnosis to treatment”, time to treatment initiation is a natural KPI; operating theatre cleaning time can only be an intermediate indicator.
  2. Can its data be produced reliably? When electronic health record data from 63 oncology practices in the United States were examined, only 2 of 19 oncology quality measures tied to the payment system could be calculated for more than 1% of patients (Schorer et al., 2022). An indicator without data remains an empty box on the dashboard or, worse, a misleading number.
  3. Is it clear who will do what when its value changes? An indicator without an owner and an action plan is watched but not managed.

It also helps to know that quality indicators are used for different purposes. In joint work by the US Veterans Affairs Radiation Oncology programme and ASTRO, 18 common measures were developed for five tumour sites and classified as 13 quality, 4 surveillance and 1 aspirational measure (Park et al., 2022). This distinction can be carried over to the dashboard: some indicators are managed today, some are only watched, and some express the institution’s ambition for tomorrow. In value-based healthcare it is recommended that, alongside survival and disease control, patient-reported outcome measures (PROMs) be included among the indicators (Abdalla et al., 2022). Indicators that measure avoidance of low-value care are still a minority; only 18% of 313 cancer quality measures compiled from six organisations serve this purpose (Ellsworth et al., 2022).

The indicator passport

Preparing a one-page “indicator passport” for each KPI ends definitional arguments before they start. The example below is completed for time to treatment initiation; the target and threshold values are examples only, and each institution should set its own.

FieldExample content for time to treatment initiation
DefinitionCalendar days from the date of pathological diagnosis to the day the first definitive oncological treatment starts
Numerator and denominatorNumerator: new patients starting treatment within 30 days. Denominator: new patients starting their first definitive treatment in the period
ExclusionsCases postponed at the patient’s own request where this is documented (reported separately, not deleted)
Reporting formatMedian, 90th percentile, share of patients within target
StratificationTumour type, stage, first treatment modality (surgery, systemic, radiotherapy), branch
Data sourcePathology system, hospital information system, radiotherapy and chemotherapy scheduling records
FrequencyWeekly monitoring, monthly report to the management board
OwnerDeputy chief physician responsible for oncology services
Target and thresholdsExample: target 80%, warning 75%, action threshold 70%
Balancing measuresAdherence to MDT recommendation, first-time pass rate of plan quality assurance
If the threshold is crossedRoot cause review within 10 working days and a short note to the management board

Four layers of a balanced oncology dashboard

A single indicator means seeing the institution with one eye. The dashboard proposed in this chapter has four layers, each balancing the others:

  • Time: time to treatment initiation, time from diagnosis to MDT, time from MDT decision to treatment, radiotherapy waiting time.
  • Access and coverage: MDT coverage rate, rate of implementation of MDT recommendations.
  • Capacity: demand, capacity, utilization and backlog (LINAC, chemotherapy chairs, operating theatres, beds, diagnostic units, workforce).
  • Quality and safety: guideline adherence, monitoring of patient-reported outcomes, share of diagnoses made through emergency presentation, composite outcome measures.

If a quality indicator worsens while a time indicator improves, or if waiting grows while capacity utilization looks high, the manager should be able to see this contradiction on the dashboard.

4. Time to treatment initiation

Time to treatment initiation (TTI) is the single strongest indicator of whether all parts of an oncology hospital are working together. A blockage in any one of appointments, imaging, pathology, molecular testing, the tumour board, planning or the treatment units is reflected in this time.

4.1 Definition: when does the clock start and stop?

The most widely used definition is the number of calendar days from the date of pathological diagnosis to the day the first definitive oncological treatment starts. In the literature, however, start and end points vary widely. A systematic review of 130 articles on timing in colorectal cancer showed that time intervals were categorised arbitrarily in 83% of studies, that there was no adjustment for confounders in 50%, and that immortal time bias was present in 46% of the articles with survival as the outcome (Drosdowsky et al., 2023).

The choice of definition directly changes the number the manager sees. In a breast cancer cohort from Türkiye, “time from admission to surgery” and “time from biopsy result to surgery” could not be used interchangeably; cases in which the two measurements disagreed pointed to different bottlenecks. The authors recommended monitoring both intervals together and putting discordant cases through a short review with reason codes (Tandogan et al., 2025). In a study with kidney cancer data in England, applying the waiting time adjustment rule, which corrects for postponement at the patient’s own request, reduced the mean time at patient level from 29.2 to 27.3 days (Varma et al., 2026). In short, the figures of two branches should not be compared before the definition and adjustment rules are written in the indicator passport.

4.2 Typical values and trend

National registries show that time to treatment initiation is around one month in many countries and has lengthened over time. In Japan, the median time in the national hospital-based cancer registries for six cancer types is 33 days (Watanabe et al., 2023). In the US National Cancer Database, the median time for the 30 most common cancer types is 26 days; it rose from 21 days in 2004 to 28 days in 2015 and did not shorten in any cancer type. In stage I patients, the median time doubled from 14 to 28 days (Dafflisio et al., 2025). In the Swiss sarcoma network, the median time was reported as 30 days (Schärer et al., 2023). In the Netherlands, a six-week norm has been adopted for surgical oncology, and in 2020, 76% of patients started treatment within this period (van Vuren et al., 2024). Whether rapid growth in demand can strain the capacity for timely treatment, especially in referral centres, has also been examined (Frosch et al., 2021).

4.3 Evidence: delay does not carry the same price in every cancer

As noted in the introduction, in colorectal and breast cancer there is a relationship between delay and risk of death that grows by the week (Ungvari et al., 2025; Ungvari, Fekete, Buda, Lehoczki, Munkácsy, et al., 2026). In head and neck cancers, each additional day until the start of treatment raised the hazard of death by a small but significant amount (HR 1.003 per day), and the rise was steeper in oral cavity cancer (Frank et al., 2024). In early-stage lung cancer, a time above 50 days was associated with lower one-year and five-year survival (Tang et al., 2023). In breast cancer, starting treatment after 12 weeks was associated with a 24% higher risk of death than starting within 8 weeks (Wang et al., 2025).

Some studies, by contrast, give opposite or neutral results. In the Canadian province of Quebec, longer waiting did not worsen survival in lung cancer (Denault et al., 2022); in a national population-based cervical cancer cohort, time to curative treatment likewise showed no significant relationship with survival (Hack et al., 2022). An important reason for this difference is the waiting time paradox: physicians treat sicker patients faster, so the group treated quickly is in fact the group with the worse prognosis (Tope et al., 2025; J. R. Zhang et al., 2022). A decision model developed during the pandemic also showed that the effect of delay varies with patient, tumour, treatment and community characteristics and that uniform prioritisation rules cannot capture this variation (Hartman et al., 2020).

In recent years, pathway-specific thresholds have been proposed in place of a single general threshold. In colorectal cancer, even delays as short as four days were associated with a higher risk of metastasis in patients receiving adjuvant chemotherapy after surgery, whereas no meaningful threshold was found in patients treated with surgery alone (Nguyen et al., 2026). In Ontario, Canada, beyond the traditional 28-day target for colorectal cancer surgery, a data-derived inflection point was found at about 45 days, where the hazard of death begins to rise (Bondzi-Simpson et al., 2025).

Implication for the manager: time to treatment initiation is a system indicator; it passes no verdict on the prognosis of an individual patient. It should therefore be monitored stratified by tumour type, stage and treatment pathway, reported as median and 90th percentile rather than as a mean, and compared with pathway-specific targets set together with the clinical teams.

4.4 Splitting the time into parts: where is the time lost?

Total time is a symptom; the diagnosis is made only when the time is split into parts. At Moffitt Cancer Center, when the mean 6.9 weeks from breast biopsy to surgery was divided into three intervals, 35% of the time fell between biopsy and first consultation, 13% between first consultation and tumour board, and 52% between tumour board and surgery; the longest interval (3.6 weeks on average) lay after the tumour board, and physician capacity was identified as the main cause of delay (Loftus et al., 2014). Modelling the lung cancer diagnostic pathway in Wales with discrete event simulation showed that giving the first outpatient appointment within 7 days and streamlining investigations could gain about 20 days and raise the share of patients treated within 62 days by 20 to 25% (England et al., 2021). In early-stage lung cancer, preoperative physiological assessment and multidisciplinary evaluation were the main determinants of the time (Tang et al., 2023); in advanced disease, complex diagnostic procedures delayed treatment (Klarenbeek et al., 2023).

The table below divides the patient journey into manageable intervals. Figure 2 summarises the same journey visually.

5. MDT coverage: who comes to the table, and where does the decision go?

The multidisciplinary tumour board (multidisciplinary team, MDT) is where the treatment decision is produced in modern oncology. From the manager’s standpoint, the MDT is measured with three questions: how many patients come to the table (coverage), how quickly they reach the table and move from the table to treatment (timeliness), and to what extent the decision made at the table is carried out (implementation and adherence).

5.1 Coverage

The MDT coverage rate is the number of newly diagnosed patients discussed at the board before treatment in a given period, divided by all newly diagnosed patients in the same period who should have been discussed. Defining the denominator correctly matters: the rate reflects reality better if cases for which the guideline does not recommend discussion before treatment are left out of the denominator.

Although guidelines treat the MDT as standard, coverage in real life is incomplete. In a health services study of patients with metastatic colorectal cancer in Germany, guideline-concordant MDT discussion took place in 63% of operated colon cancer patients, 38% in stage IV colon cancer and 47% in rectal cancer (Lowes et al., 2017). When a cloud-based, asynchronous MDT platform was set up for digestive system cancers in China, coverage rose from 47.85% to 79.99%; each case was discussed in 7.68 minutes on average, and the mean response time of physicians was 27.21 hours (Y. Zhang et al., 2024). In Sweden, participation of district hospitals in the head and neck board by telemedicine was found to cost slightly less than attendance in person (Stalfors et al., 2005). These findings show that coverage depends largely on organisational design and can be extended with technology.

Who sits at the table is also an indicator. After a clinical geneticist began to attend the gynaecological oncology board in Australia, the referral rate of eligible ovarian cancer patients to genetic counselling rose from 26.7% to 51.7% (Cohen et al., 2016). In rectal cancer, mandatory MDT attendance was associated with improvement in 12 of 14 preoperative process variables and a marked increase in the completeness of total mesorectal excision (Richardson et al., 2016). In the USA, weekly board attendance by physicians caring for patients with lung and colorectal cancer was not associated with overall survival, but it raised the likelihood of clinical trial enrolment (OR 1.6) and of curative surgery in stage I to II non-small cell lung cancer (OR 2.9) (Kehl et al., 2015).

5.2 Timeliness: is the board a door or a wall?

The MDT can lengthen the time while raising the quality of the decision. In oral cavity cancer, patients discussed at the board before treatment had higher guideline adherence (79.6% against 68%) but also a longer time to the start of treatment (33.5 against 20.1 days); there was no significant difference in three-year survival (Burkhardt et al., 2024). In contrast, a well-designed multidisciplinary breast clinic in a safety-net hospital reduced time from diagnosis to treatment from 46.9 to 35.0 days (Kobzeva-Herzog et al., 2026). The difference lies in how the board is organised: a board that meets once a week and defers incomplete files to the following week becomes a wall; a board that assesses on the same day and has missing investigations completed beforehand works as a door.

5.3 Implementation and adherence: does the decision stay on paper?

The rate at which board decisions are carried out (MDT adherence or implementation rate) is monitored less than coverage but is at least as important. In Germany, 75.5% of the recommendations of a lung cancer board were guideline-concordant and 15.6% went beyond the guideline, and about 90% of recommendations were put into practice (Walter et al., 2023). In digestive system cancers, although 76% of recommendations were fully guideline-concordant, the full implementation rate was only 64%; the main reasons for deviation were comorbidities and a different preference on the part of the patient (Krause et al., 2023).

The relationship between unimplemented decisions and outcome is striking. Among 4,501 patients with early breast cancer in China, 81.8% followed the MDT recommendation; disease-free survival (HR 1.813) and overall survival (HR 2.478) were worse in the non-adherent group (Yang et al., 2020). In upper gastrointestinal cancers with a chance of curative treatment, 41.8% of patients did not follow the recommendation, the most frequent reason being patient refusal (50%) (Soon et al., 2023). In stage III non-small cell lung cancer in Switzerland, adherence was 70.4%, and non-adherence was associated with worse event-free and overall survival (Koster et al., 2025). In a study of gynaecological cancer boards, the recommendation was not followed in 19.5% of board decisions, and non-adherence was associated with shorter survival (Naessens et al., 2023). In colorectal cancer too, the most frequent reason for non-adherence was patient preference (Kandemir et al., 2025).

These relationships should not be read as causal; patients who fall outside the recommendation are often older, frailer or at a more advanced stage. The message for the manager is nevertheless clear: the reason for non-adherence should be recorded and classified with codes such as “patient preference”, “change in clinical condition”, “capacity” and “communication breakdown”. Non-adherence caused by capacity or communication is the direct responsibility of management. A consensus text on surgical oncology networks likewise describes the MDT as the “cognitive backbone” of the network while warning about the risks of hierarchy, protocol-bound decisions and diffusion of responsibility, and recommends structured audit and transparent documentation (Nicolai et al., 2026). Population-based findings showing that patients who receive multidisciplinary consultation are more likely to receive guideline-recommended adjuvant treatment also support this approach (Sanchez et al., 2024).

6. Radiotherapy waiting time

Radiotherapy waiting time shows how well the most expensive and least flexible resource of the oncology hospital (the linear accelerator, the physics and dosimetry team, the radiation oncologist’s time) is managed. The number of LINACs cannot be increased quickly; waiting in radiotherapy is therefore usually reduced by reorganising the workflow before buying a new machine.

6.1 Definition: not one wait but a chain

Starting radiotherapy consists of linked steps: the treatment decision, computed tomography simulation, contouring of targets and organs at risk, dosimetric planning, plan-specific quality assurance, plan verification and the first fraction. Process modelling of a clinic with a single physician and a single LINAC showed that when the weekly number of new patients rose from 1 to 10, mean time from simulation to treatment increased from 4 to 7 days and the maximum from 6 to 12 days (Chowdhry & Simpson, 2023). This result recalls a basic fact of queueing theory: as resource utilization approaches one hundred per cent, waiting grows not linearly but rapidly. The manager’s reading “the machine is completely full, so we are efficient” is therefore dangerous.

The recommended main indicator is the time from the radiotherapy decision (or referral to the radiotherapy department) to the first fraction. Intermediate indicators are time from simulation to first fraction, planning turnaround time and the first-time pass rate of plan quality assurance. In adjuvant radiotherapy, the time from the end of surgery or systemic treatment to radiotherapy should also be monitored.

6.2 Evidence and trend

During a period in Ontario, Canada, when radiotherapy waiting times were unusually long because of capacity problems, event-free survival was worse in patients with early breast cancer who had not received chemotherapy and who waited 12 weeks or more from surgery to radiotherapy (Raphael et al., 2020). In US Commission on Cancer centres, the median time from breast-conserving surgery to radiotherapy lengthened from 43 days in 2004 to 48 days in 2020; among the new breast cancer quality measures, radiotherapy timing was the one met least often, and only 35.2% of centres reached the 80% performance level (Fefferman et al., 2025).

Behind capacity there is usually the workforce. In the United Kingdom, the shortfall of consultant clinical oncologists is currently reported as 17% and is expected to reach 26% in 2030; the authors stress that this shortfall increases radiotherapy delays (Vulpe et al., 2026).

6.3 How is waiting reduced?

  • Process management: in a radiation oncology department in Spain, moving to a process management model shortened waiting times for first consultation and for the start of treatment, lowered cost per patient and, thanks to hypofractionated schedules, saved 6,035 sessions in one year (Lupiáñez-Pérez et al., 2017). Hypofractionation is a powerful lever that expands capacity in clinically eligible patients, but it must always be considered together with the clinical indication.
  • Clearing administrative bottlenecks: a radiation oncology department in the USA carried out a root cause analysis of insurance prior authorisation delays and redesigned clinical treatment plan templates and the prior authorisation workflow using Plan-Do-Check-Act and A3 methods (Tran et al., 2025). Even where there is no prior authorisation, similar administrative steps (reports, approvals, procurement of materials) are the invisible waiting areas of radiotherapy.
  • Patient navigation: in Brazil, the national breast cancer patient navigation programme shortened time from diagnosis to radiotherapy by about 10 days compared with the comparison group; in the same period, radiotherapy costs rose by about 16.5%. The authors interpreted this rise as previously unmet demand becoming visible (da Silva & Postali, 2026).
  • Keeping the balance between quality and speed: in thoracic stereotactic radiotherapy, pre-treatment peer review at two meetings a week aimed to raise quality without creating routine treatment delays, and the level of compliance was monitored with a statistical process control chart (Kut et al., 2023).
  • Communication: interviews with radiation oncologists in India showed that unavoidable waits can be made more bearable for patients through two-way communication and organisation of the waiting area (Saini et al., 2022).

7. Capacity indicators: demand, capacity and spare capacity

Capacity indicators answer the “why” of waiting times. Time indicators say that there is a problem; capacity indicators show whether the problem stems from excess demand, from insufficient resources or from resources standing in the wrong place.

7.1 Four core concepts

  • Demand: the number of patients or procedures needing service in a given period (for example new radiotherapy patients per week).
  • Capacity: the maximum amount of service that can be produced in the same period with the available people, machines, beds, chairs and time.
  • Utilization: the ratio of service delivered to capacity.
  • Backlog: the number of patients in the queue who have not yet received service.

These four concepts should be read together. If demand persistently exceeds capacity, the backlog grows and waiting lengthens. If waiting lengthens although demand is below capacity, the problem usually lies in flow, appointment design or the misallocation of resources.

7.2 The spare capacity paradox

Spare capacity can exist even in a system with long waiting lists. In England, the “maximum surgical capacity” of each hospital performing breast and colorectal cancer surgery was defined as the highest value of its six-month moving average volume. By this measure, 40.4% of hospitals performing breast surgery and 50.3% of those performing colorectal surgery used less than 80% of their maximum capacity. Spare capacity was greater in centres that lost their patients to more distant hospitals (Aggarwal et al., 2023). This finding corresponds directly to the problem of “under-use of capacity in some branches” in the Module II case: the main site can overflow while a branch stands empty, and the solution is to redesign patient referral before making new investments.

Capacity can also be tracked not only by volume but by the number of patients served within target. The case throughput metric developed in England relates the number of patients meeting the waiting standard to the pre-pandemic level, providing a measure of resilience that is comparable between institutions; it showed that diagnostic and referral pathways suffered greater and more lasting losses than treatment pathways (Lam et al., 2026).

7.3 Demand is not fixed

When capacity is increased, demand can change too. In a pilot in England that shortened waiting times for urgent diagnosis of suspected cancer, the share of patients with suspected colorectal cancer exceeding the waiting target fell by 3.9 points, but referrals from general practitioners referring to the pilot hospitals rose by 10.8% (Hayes et al., 2024). Shorter waits attract new demand; the effect of a capacity increase can therefore partly melt away after a while. In the USA, time from diagnosis to treatment shortened in 2020 during the pandemic and lengthened again in 2021 and 2022; the authors believe workforce constraints played a part in the later lengthening (Fan et al., 2025).

7.4 Capacity indicators at unit level

ResourceExample capacity indicatorsInterpretation tip and example from the literature
Linear acceleratorDaily operating hours, fractions per day, utilizationWaiting grows rapidly as utilization approaches one hundred per cent (Chowdhry & Simpson, 2023)
Day chemotherapy unitChair occupancy, time from appointment to start of infusion, drug preparation timeWith design thinking and regimens prepared in advance, the time to start of morning treatments fell from 83 to 45 minutes (Jen et al., 2023); a lean and DMAIC approach reduced waiting by 19% (Radheshyam et al., 2024)
Oncology pharmacyDrug preparation turnaround time, share of early prescriptionsEarly prescribing, advance preparation, robotic compounding and lean management are recommended (Giraud et al., 2026)
Systemic treatment flowShare of delays of more than 7 days between cyclesIn early breast cancer, 17% of patients had a delay of more than 7 days between cycles, and this delay was associated with five-year mortality (HR 1.33) (Steventon et al., 2024)
Operating theatre and bedsPlanned theatre utilization, cancellation rate, length of stayMinimally invasive surgery shortened length of stay in lobectomy by 1.87 days compared with open surgery (Ricciardi et al., 2022)
Bed turnover30-day unplanned readmission ratePalliative care consultation was associated with a lower rate of readmissions in ovarian cancer (Francoeur et al., 2025)
ImagingWaiting time for CT and MRIWith targeted additional funding, waiting time for CT and MRI in suspected cancer fell from 17.2 to 4.2 days (Papp et al., 2023)
Molecular pathologyTurnaround time from specimen collection to reportWith parallel specimen processing and closed-loop communication, median time to report fell from 22 to 16 days (Yeo et al., 2025)
WorkforceWorkload per physician, nurse, physicist and dosimetristWorkforce shortage is one of the main causes of radiotherapy delay (Vulpe et al., 2026)

7.5 Simulation: trying the decision on the computer before trying it on the ground

Capacity decisions are expensive and hard to reverse. Discrete event and agent-based simulation models are therefore used to test in advance questions such as “should we buy a second LINAC or strengthen the planning team?” A configurable simulation model developed for an oncology department in Italy working with an external pharmacy helped choose the configuration that would most reduce patient waiting time by comparing different departmental layouts (Corsini et al., 2023). The lung cancer model in Wales tested “what if” scenarios in a similar way (England et al., 2021).

8. Quality indicators: accuracy alongside speed

Time and capacity indicators show how fast the hospital works; quality indicators show whether it does the right thing in the right way. In oncology, speed is not a value in itself; starting the wrong treatment quickly can be more harmful than starting the right treatment a few days late. Every time indicator should therefore be accompanied by at least one quality indicator as a balancing measure.

8.1 Oncology quality indicators through the Donabedian triad

DimensionOncology exampleA finding from the literature
StructureAccreditation, existence of a tumour board, registry system, number of specialistsIn the US state of Iowa, Commission on Cancer accreditation was the strongest independent predictor of high hospital performance on four quality measures (Schroeder et al., 2022)
ProcessGuideline-concordant treatment, PRO monitoring, adequate lymph node samplingAmong patients with lung cancer receiving systemic treatment, adherence to completing PRO forms was 49.4% overall and ranged from 27.2% to 70.0% between centres (Takvorian et al., 2022)
Diagnostic processShare of cancer diagnoses made through emergency presentationA digital quality measure showed that in the Veterans system 20.9% of lung cancers and 22.4% of colorectal cancers were diagnosed after an emergency presentation; missed diagnostic opportunities were found in a substantial share of these cases (Kapadia et al., 2024)
OutcomeComposite outcome measures, risk-adjusted mortalityIn endometrial cancer surgery, the “textbook oncologic outcome”, meaning that all six criteria are met, was achieved in 81% of patients and was associated with better five-year survival (adjusted HR 0.46) (Caruso et al., 2025)

8.2 Four principles for choosing quality indicators

  1. No comparison without risk adjustment. In surgery for central nervous system tumours, the risk-standardised mortality ratio and hospital volume classified different centres as “good”; high volume does not always mean low risk (Chalif et al., 2024).
  2. Feedback, not measurement, brings improvement. In a regional surgical quality programme in the USA, after institutions received detailed feedback on rectal cancer measures, use of preoperative MRI rose from 32% first to 88% and then to 92%, and the rate of total mesorectal excision from 47% to 68% and 80% (Charboneau et al., 2025). In the Australian lung cancer clinical quality registry, 25 indicators in 12,121 patients were met across a very wide range between institutions (2.1% to 90%), and meeting most of the indicators was associated with a lower hazard of death (Stirling et al., 2025).
  3. Indicators can hide inequality. Most national quality frameworks do not report results broken down by socioeconomic group; stratified reporting of indicator results is recommended (T. Nash et al., 2026). In a public referral hospital in Brazil, only 35% of patients with hormone receptor-positive breast cancer started endocrine therapy within the recommended time (Lima et al., 2026).
  4. The quality indicator is the counterweight of speed. In projects to shorten time, indicators such as guideline adherence, plan quality assurance, unplanned readmission and patient experience should be monitored on the same dashboard. Even in countries where quality measurement in oncology is tied to payment and reporting programmes, many patients have been shown not to receive optimal care (Kline et al., 2024).

9. Target, threshold and variance: the grammar of reading a number

An indicator gains meaning only when it is compared with a target; a variance becomes a managerial signal only when it is separated from natural fluctuation. This section deals with the two questions a manager should ask when reading a number: where does our target come from, and is the change we see real?

9.1 Where does a target come from?

Targets draw on four sources, and a good target usually uses several together:

  • National or international standards. The six-week norm for surgical oncology in the Netherlands (van Vuren et al., 2024) and, in England, the standards of a specialist appointment within 2 weeks, 31 days after the decision and 62 days after referral (Quinn et al., 2024) are of this kind.
  • Evidence-based thresholds. In Ontario, alongside the traditional 28-day target for colorectal cancer surgery, an inflection point of about 45 days derived from survival data has been defined (Bondzi-Simpson et al., 2025). Pathway-specific thresholds are proposed in colorectal cancer (Nguyen et al., 2026).
  • The institution’s own history. The institution’s median value over the last 12 months is taken as the baseline, and a realistic rate of improvement is targeted.
  • Benchmarking. As in the Swiss sarcoma network, comparison is made with real-world data from similar centres (Schärer et al., 2023).

An unrealistic target is as harmful as no target. In Northern Ireland, across a three-cycle improvement project in patients undergoing lung lobectomy, only 5.8% of patients overall met the 62-day target and 16.3% the 31-day target (Campbell et al., 2026). A target that seems impossible to reach breeds indifference in the team; intermediate targets and a step-by-step improvement plan are important for this reason.

9.2 Threshold gaming: when the target starts to measure itself

When a measure becomes a target, it changes behaviour. When the performance of hospital trusts in England against cancer waiting standards was examined, strong statistical evidence was found of a “threshold effect”, a clustering just above the target, especially for the 62-day standard tied to financial sanctions (Quinn et al., 2024). Some hospitals, that is, may have prioritised according to the target itself rather than clinical need. A classic study of the target regime in the English health system likewise showed that targets can improve performance but are open to gaming through the perception that “what is measured matters, what is not measured does not” (Bevan & Hood, 2006). For this reason, the whole distribution (median, 90th percentile, waiting time of patients exceeding the target) should be monitored rather than a single threshold, and cases “fitted” within the target should be reviewed with reason codes.

9.3 Not every change is a signal: control chart logic

Statistical process control (SPC) was developed to separate the natural fluctuation of a process (common cause) from the signals that depart from it (special cause), and it has been adapted successfully to healthcare (Benneyan et al., 2003). A control chart consists of data plotted over time, a centre line, and control limits usually placed three standard deviations above and below the mean (Mohammed et al., 2008). A physician can read this chart like the consecutive laboratory values of a patient: a single value crossing the control limit, many consecutive values lining up on the same side of the centre line, or a steadily rising trend shows that something in the system has changed.

Control charts are used in oncology in both clinical and managerial areas:

  • Improving waiting time: in a high-volume paediatric neuro-oncology outpatient clinic, a process map and Pareto charts identified physician and room availability as the main causes of delay; successive PDSA cycles were monitored with run charts and Shewhart charts. The share of patients waiting more than 30 minutes to be roomed fell from 21% to 13% and mean waiting from 21 to 11 minutes (Vinitsky et al., 2022).
  • Radiotherapy quality assurance: in plan-specific quality assurance, control charts are used to set the tolerance limit and the action limit (H. Y. Zhang et al., 2022; Singh et al., 2026). Patient set-up and brachytherapy plan quality are assessed with the process capability index (Cpk) (Li et al., 2021; Chen et al., 2025). In prostate brachytherapy, examining out-of-control points revealed oedema as a cause explaining dosimetric variability (Nasser et al., 2022).
  • Diagnostic variability: differences in breast cancer grading between pathologists have been made visible with control charts (Moodley et al., 2020).
  • Advanced methods: risk-adjusted cumulative sum (CUSUM) charts, which take patient risk into account, are being developed for monitoring breast cancer treatment processes (Rafiei, 2026).

The distinction between “tolerance limit and action limit”, borrowed from radiotherapy physics, is a powerful model for managerial indicators as well. Managers generally use three zones on their dashboards: a target zone, a warning zone and an action zone (Figure 3).

ZoneMeaningWhat does the manager do?
Green: target zoneThe value is on target and within control limits; fluctuation is common causeDoes not intervene, keeps monitoring, recognises the team
Amber: warning zoneThe value has moved away from the target but has not crossed the action threshold, or a trend has begunVerifies the data, splits into intervals, increases the frequency of monitoring
Red: action zoneThe action threshold has been crossed, or the control chart has given a special-cause signalStarts a root cause analysis, sets an owner and a deadline, informs the management board

9.4 Not every variance is bad, and not every difference matters

Variance analysis has long been used in the management of clinical pathways. In a clinical pathway for video-assisted lung lobectomy, variances occurred in 1.6% to 34.4% of cases depending on the activity, and complications and abnormal body mass index were independent factors that increased variance (Okita et al., 2009). An analysis of this kind helps separate the patient groups in which a variance is to be expected from those in which it points to a system problem.

Sometimes large differences make no meaningful difference to the result. In the Finnish cervical cancer screening programme, laboratories differed by factors of 3.6 to 4 in follow-up recommendation and referral rates, yet these differences did not noticeably change the effectiveness of the programme (Lönnberg et al., 2012). The manager’s task is not to intervene in every difference but to find the difference that affects the outcome.

One indicator, three zones: each zone calls for a different managerial responseTime indicator example, higher is worse; schematic drawing with no real valuesAction limitWarning limitTargetexample runTime (weeks)Duration (days)special-cause signalRed: action zoneAmber: warning zoneGreen: target zoneRoot cause, owner, deadline;note to the management boardVerify the data, split intointervals, monitor more oftenDo not intervene, keepmonitoring, recognise the team
Figure 3. Target, warning and action zones. The logic of tolerance and action limits in radiotherapy quality assurance is carried over to the managerial indicator; the trend begins in the warning zone, and once the action limit is crossed a root cause analysis becomes mandatory.

10. From variance to managerial intervention: a six-step decision cycle

A variance is not an end but a beginning. The manager’s strength comes not from seeing the variance but from choosing the intervention that fits it and monitoring the result. The six steps below carry the path a physician follows at the bedside to the management table.

  1. Verify the variance. First ask whether the number is real. Has the definition changed, are data missing, has a new branch been added? It should be remembered that electronic records are often insufficient for calculating quality measures (Schorer et al., 2022) and that adjustment rules change the result (Varma et al., 2026).
  2. Disaggregate. The total value is broken down by tumour type, stage, treatment pathway, branch and interval of the patient journey (A1 to A5). The problem is usually concentrated in a single interval or a single branch.
  3. Determine the type of variation. If the control chart gives a special-cause signal (a sudden jump, a one-off event), a local fix may be enough. If the variation is common cause, that is, if the system produces this result by design, the system should be redesigned rather than individuals blamed (Benneyan et al., 2003).
  4. Find the root cause. The Module II programme recommends examining root causes in five dimensions: process, people, communication, capacity and resources. The fishbone diagram, the “5 whys” and the process map are the basic tools of this step. Where clinical teams blame one another, the process map moves the discussion from persons to flow.
  5. Select the intervention. The intervention should fit the root cause, have evidence behind it, be feasible and be affordable. The table below offers a menu compiled from the literature.
  6. Set the owner, the deadline and the monitoring. Every intervention should have an owner, an end date, a target indicator and at least one balancing measure. The control chart continues to be updated in order to see the effect.

10.1 An evidence-based menu of interventions

Root causeInterventionExample of effect from the literature
Delay in referral and first appointmentFast-track diagnostic pathwayIn head and neck cancer, median referral time fell from 9 to 5 days and time from referral to treatment from 50 to 43 days; no difference in survival was seen (Lorenzana et al., 2026)
The patient getting lost in the system, lack of coordinationPatient navigationIn gastrointestinal cancers in Rwanda, median time from pathology report to treatment fell from 53.5 to 32 days (Kwizera et al., 2026); in Brazil, time from diagnosis to radiotherapy shortened by about 10 days (da Silva & Postali, 2026)
Sequential, disconnected appointments across specialtiesSame-day multidisciplinary clinicIn breast cancer, time from diagnosis to treatment fell from 46.9 to 35.0 days (Kobzeva-Herzog et al., 2026)
Disconnection between surgery and oncologyJoint clinic and patient poolingMean time from referral to lobectomy fell from 150.47 to 109.67 days, a reduction of 27% (Campbell et al., 2026)
Delay in molecular testingParallel specimen processing, closed-loop communicationMedian time from specimen collection to report fell from 22 to 16 days (Yeo et al., 2025)
Biomarker result requested after diagnosisLiquid biopsy before diagnosisIn advanced lung cancer, median time from diagnosis to treatment fell from 35 to 21 days (Russo et al., 2024); the question has also been tested in a prospective clinical trial (García-Pardo et al., 2023)
Comprehensive panel taking too longRapid single-gene testA rapid test for EGFR shortened time to the start of treatment by 10.1 days on average (25%) (Banyi et al., 2022)
Waste and waiting in the diagnostic pathwayLean patient pathwayIn breast cancer surgery, waiting on the lean pathway was 9.3 days shorter on average than on the traditional pathway (Freeze et al., 2025); in prostate cancer, median time from biopsy to result fell from 21 to 15 days and time to the treatment consultation from 63 to 38 days (Soroush et al., 2025)
Imaging queueTargeted additional funding and capacityWaiting time for CT and MRI in suspected cancer fell from 17.2 to 4.2 days (Papp et al., 2023)
Morning peak in day treatmentAdvance preparation and appointment redesignTime to start of morning treatments fell from 83 to 45 minutes (Jen et al., 2023)
Low board coverageCloud-based, asynchronous MDTCoverage rose from 47.85% to 79.99% (Y. Zhang et al., 2024)
Differences between institutions in quality indicatorsData reporting and feedbackUse of preoperative MRI in rectal cancer rose from 32% to 92% (Charboneau et al., 2025)
Uncertainty in capacity decisionsScenario testing with simulationA gain of about 20 days was projected in the lung cancer diagnostic pathway (England et al., 2021)

Two lessons follow from this table. First, most interventions that shorten time are not major investments but changes in flow and coordination. Second, process indicators improve much faster than outcome indicators: the fast-track pathway in head and neck cancer shortened times but made no significant difference to survival (Lorenzana et al., 2026). When judging the success of an intervention, the manager should allow for this time lag and follow outcome indicators over a longer window.

10.2 The output of the management decision: a one-page decision chain

The expected output of the Module II workshop is the completion, on a single page, of the following chain: Problem → Strategic goal → KPI → Root cause → Stakeholders → Intervention → Owner → Communication approach → Timeline → Expected result. This chain forms the skeleton of the note to be presented to the management board. Every link must rest on the one before it; for a problem whose root cause is defined as “communication”, for example, the only intervention proposed cannot be “purchase of a new machine”. The next section shows how this chain is completed for the case.

11. Worked case: from a missed target to a note for the management board

This case is a version of the scenario used in the Module II workshop, enriched with numbers. All values in the table are fictional, constructed for teaching, and do not belong to any real hospital.

11.1 The situation

One of the hospital’s strategic goals this year is to reduce the time from diagnosis to the start of treatment. Over the last three quarters, however, the picture is as follows:

IndicatorQuarter 1Quarter 2Quarter 3Example target
Median time from diagnosis to treatment (days)28344130 or less
Share of new patients starting treatment within 30 days62%51%42%75% or more
MDT coverage rate88%86%85%90% or more
Median time from diagnosis to MDT decision (days)10111110 or less
Median time from MDT decision to treatment (days)12172414 or less
On-time implementation rate of MDT decisions81%72%63%85% or more
Median time from radiotherapy decision to first fraction (days)18243121 or less
LINAC utilization, main campus91%95%98%Set by the institution
LINAC utilization, Branch A72%66%61%Set by the institution
Patient complaints about waiting (number)121931Decrease

The surgical team believes the delay comes from radiotherapy, the radiation oncology team from the tumour board, and medical oncology from operating theatre capacity. Branch managers say they are not involved in decisions.

11.2 Solution in six steps

1. Verify the variance. The data team confirms that definition and data source did not change over the three quarters and that the data of Branch A arrived complete. The variance is real. Time from diagnosis to treatment and the 30-day rate have moved into the action (red) zone.

2. Disaggregate. When the total time is split into intervals, the time from diagnosis to MDT decision is almost constant (10 to 11 days). The MDT coverage rate, although slightly below target, is also stable. Almost all of the increase lies in the interval from MDT decision to treatment (from 12 to 24 days). Breaking down by treatment modality shows that the greatest lengthening is in patients receiving radiotherapy. The problem, then, is not “the board does not meet” but “the board’s decision is put into practice late”. This finding ends the blame debate between the teams with data.

3. Determine the type of variation. On the weekly control chart, all of the last eight weeks of the third quarter lie above the centre line, and there is a sustained rise. This is not a one-off failure but a signal that the system has settled at a new level. The focus is therefore on system design rather than individual blame.

4. Find the root cause. The five-dimension review gives the following picture:

DimensionFinding (fictional)
ProcessIt is not defined who books the radiotherapy simulation appointment after the MDT decision; the decision form has no target date field
PeopleA dosimetrist left the main campus and was not replaced; planning turnaround time has lengthened
CommunicationBranch A physicians do not join the board; physicians at the main campus are unaware of Branch A’s capacity
CapacityLINAC utilization at the main campus has reached 98% and the queue is growing fast; at Branch A the machine is used at 61%
ResourcesThere is no regular shuttle for patient transport to Branch A; patients prefer the main campus

This picture mirrors the spare capacity finding in England: a queue grows in one place while capacity stands idle in another (Aggarwal et al., 2023). Utilization approaching one hundred per cent at the main campus explains, by queueing logic, the rapid lengthening of waits (Chowdhry & Simpson, 2023).

5. Select the intervention. In terms of impact and feasibility, the team chooses the following package:

  • Decision card and ownership: “responsible physician” and “target treatment date” fields are added to the MDT decision form; an oncology nurse is assigned as navigator for each decision (Kwizera et al., 2026).
  • Radiotherapy referral protocol: a rule for referring clinically suitable patients to Branch A is written, a shuttle is arranged for patient transport, and Branch A physicians join the board remotely (Y. Zhang et al., 2024).
  • Planning capacity: the vacant dosimetrist post is filled; temporarily, the planning team of Branch A works jointly with the main campus.
  • Weekly capacity huddle: a 15-minute weekly capacity meeting is held with representatives of radiotherapy, surgery and medical oncology; the control chart is read at this meeting.
  • Hypofractionation review: the use of hypofractionated schedules in clinically suitable patients is reassessed by the radiation oncology team (Lupiáñez-Pérez et al., 2017).

6. Owner, deadline and monitoring. An owner and a date are set for each intervention. The main indicator is “median time from MDT decision to treatment”. The balancing measures are the first-time pass rate of plan quality assurance at Branch A, the rate of adherence to MDT recommendations, and patient experience.

11.3 A one-page note for the management board

LinkContent

KPIShare starting treatment within 30 days; median time from MDT decision to treatment; median time from radiotherapy decision to first fraction
Root causeDecisions without an owner, loss of planning workforce, and over-utilization at the main campus coexisting with spare capacity at the branch
StakeholdersRadiation oncology, surgery, medical oncology, Branch A management, nursing, patient transport unit, patients and relatives
InterventionDecision card and navigator, referral protocol and shuttle to Branch A, dosimetrist recruitment, weekly capacity huddle, hypofractionation review
OwnersDeputy chief physician (overall coordination), head of radiation oncology, Branch A manager, head of oncology nursing
Communication approachData, not blame: the disaggregated time chart is shared with all teams; the Branch A team is made a partner in the decision; the reason for referral to the branch is explained clearly to patients
TimelineFirst 30 days: decision card, navigator, weekly huddle. 60 days: referral protocol and shuttle. 90 days: first evaluation
Expected resultMedian time from MDT decision to treatment approaching 14 days at 90 days, and the 30-day rate approaching 75% at 6 months; higher LINAC utilization at Branch A and a shorter queue at the main campus

This note is also the template for the “Executive Improvement Project” that participants in Module II will prepare for their own hospitals.

12. Common mistakes and how to avoid them

PitfallWhat happens?How to avoid it
1. The mean trapWaiting times are right-skewed; a few patients with very long waits distort the mean and hide the majorityReport median, 90th percentile and share of patients within target together
2. Definition driftThe moment the clock starts and stops differs from branch to branch; numbers become incomparable (Drosdowsky et al., 2023; Tandogan et al., 2025)Write an indicator passport and record any change of definition with its date
3. The waiting time paradoxBecause sicker patients are treated quickly, the false conclusion emerges that “waiting is good” (Tope et al., 2025)Use the time indicator as a system indicator and read its relationship with outcome stratified and risk-adjusted
4. Threshold gamingThe target overrides clinical priority; patients are “fitted” just under the target (Quinn et al., 2024; Bevan & Hood, 2006)Monitor the whole distribution and also report the waiting time of cases exceeding the target
5. Demand responseWhen waiting shortens, referrals rise and the gain melts away (Hayes et al., 2024)Include demand growth as a scenario in the capacity plan
6. Loss of quality for the sake of speedThe board is skipped or plan checks are shortened (Burkhardt et al., 2024)Place a quality indicator next to every time indicator
7. An indicator without dataThere is a number on the dashboard but it is not reliable (Schorer et al., 2022)Test the data source and completion rate before choosing the indicator
8. Billing a common cause to a personIndividuals are blamed for a problem that stems from system design, and the team becomes defensive (Benneyan et al., 2003)Separate common and special cause with a control chart; solve system problems with the system
9. The volume equals quality fallacyA high-volume unit is automatically assumed to be good (Chalif et al., 2024)Use risk-adjusted outcome indicators
10. Inequality behind the averageThe delay of patients who live far away or are disadvantaged is invisible in the total (Wang et al., 2025; T. Nash et al., 2026)Break results down by groups such as place of residence, insurance status and age
11. Impatience for outcomesThe process improves but survival does not change at once, and the project is declared a “failure” (Lorenzana et al., 2026)Set different evaluation windows for process and outcome indicators

13. Pocket card for physicians: a gift package from performance management

This section is the summary of the chapter that can be cut out and kept on the desk.

Monday morning questions

  1. Of the patients diagnosed last week, how many will start treatment within 30 days and how many are at risk?
  2. Which is the longest interval in our time to treatment initiation: diagnosis, the board, or after the board?
  3. How many of the decisions we made at the board have an owner and a target date?
  4. Where is our LINAC, chair and theatre utilization approaching one hundred per cent, and where is it standing idle?
  5. Where we speeded up this week, did we compromise on quality?

Ten golden rules

  1. The clock is a clinical finding; read it together with tumour type, stage and treatment pathway.
  2. Choose few indicators that produce decisions, and give every indicator an owner.
  3. Use the median and the 90th percentile, not the mean.
  4. Do not make a diagnosis before splitting the total time into parts.
  5. Measure the MDT not only by coverage but by time after the decision and by implementation rate.
  6. When utilization approaches one hundred per cent, waiting grows rapidly; “completely full” does not always mean “efficient”.
  7. Look for spare capacity first, then ask for new investment.
  8. Place a quality indicator next to every time indicator.
  9. For a common cause fix the system, for a special cause fix the event; target the process, not the person.
  10. Process changes fast and outcome slowly; monitor patiently and feed the results back to your team.

14. Conclusion

Performance management in an oncology hospital is the work a physician does at the bedside carried to the scale of the institution: measuring the finding correctly, making the differential diagnosis correctly, choosing the appropriate treatment and monitoring the result. Time to treatment initiation, MDT coverage and radiotherapy waiting time are the most visible findings of this work; capacity and quality indicators show the cause and the cost of those findings.

The literature is clear on three points. First, the price of delay varies with cancer type and treatment pathway; pathway-specific targets set together with the clinical teams are therefore needed in place of a single universal threshold. Second, the value of the MDT lies not only in its meeting but in the timely and complete implementation of its decision. Third, most interventions that shorten waiting times are not major investments but changes in flow, coordination and ownership.

The manager’s task is not to react to every number but to separate signal from noise and tie the right intervention to the right signal. Once this relationship between target, threshold, variance and intervention is established, the indicator ceases to be a column in a report and becomes a management decision that touches the day on which the patient reaches treatment.
