Hunting, Not Judgment.

A Geschäftsführer once asked me whether her physicians were simply slower than the benchmark. The controlling report showed cases per consultant FTE running about 15% below peer hospitals, and her medical director had begun framing the conversation as a performance management problem. Before the conversation drifted further in that direction, I asked whether the hospital had ever observed, directly, where a consultant’s working day actually went. It had not. No hospital I have worked with has done this rigorously. And until it has, the question of whether physicians are “underperforming” is unanswerable — because the baseline being compared against is a perception, not a measurement.

The PRIME layer of CuraOS exists specifically for this category of problem. Not as performance management, not as physician-engagement methodology, and not as a productivity framework. As a discipline for treating physician time as a measurable, instrumentable flow — and for hunting the structural leaks in that flow rather than judging the clinicians whose time is being leaked.

The distinction matters because the two approaches produce opposite organisational responses. A judgment approach asks: are these physicians fast enough, efficient enough, appropriately utilised? A hunting approach asks: what specific structural features of our hospital are currently consuming physician hours that should be going to patients? The first approach creates defensiveness, attrition, and interviews at the competitor [1]. The second approach produces a specific list of fixable leaks, each owned, each tracked, each closeable.

The observation at the foundation of every PRIME-layer conversation: your physicians are not the leak. Your hospital is the leak, and your physicians are the ones bleeding.

What the hunt actually finds.

When a hospital commissions even a lightweight shadow study — a few days of structured observation of a representative consultant’s working shift, documented in fifteen-minute time blocks — the same five leaks appear, every time, across every specialty. The proportions vary. The categories do not.

The combined range — 22 to 39 percent of the clinical shift spent on these five leaks — is what makes the PRIME layer such a high-leverage conversation. A hospital that closes even half of this gap recovers the equivalent of one consultant FTE per 8-10 consultants on the schedule, without any change to headcount, without any change to clinical performance, and without any change to physician compensation. The arithmetic is not subtle. The operational conversation that surfaces the arithmetic almost never happens.

Why the hunt rarely gets commissioned.

Three structural reasons keep hospitals from commissioning this kind of observation.

It looks like surveillance. A shadow study, described carelessly, sounds like time-and-motion monitoring of doctors. Physicians who have read about the mortgage-brokerage and warehouse-efficiency origins of this kind of observation react defensively. If the framing is not managed properly from the outset — “we are hunting the hospital’s structural leaks, not evaluating physician pace” — the exercise generates more attrition risk than insight.

It produces uncomfortable findings about non-medical functions. The five leaks are almost never caused by physicians. They are caused by radiology turnaround, IT system design, ward clerk staffing, admission-pathway architecture, inter-service referral protocols, and the absence of a structured on-call handover. Closing the leaks requires changes in functions that do not report to the medical directorate and whose performance has not been subject to this kind of specific accountability. Leadership teams that are politically unwilling to open these conversations with support-function heads will not commission the study.

It requires a named owner with cross-functional authority. A Chefarzt who observes that radiology turnaround is costing her department six percent of consultant time has no authority over radiology. A Geschäftsführer has the authority but rarely the operational specificity. The conversation that connects the finding to a remediation requires someone who can sit between the clinical and support functions and produce an agreement. Most hospitals do not have this role. The PRIME layer will not be built until someone does.

Cross-specialty pattern.

The five leaks generalise across specialties with predictable weightings. In internal medicine and geriatrics, the radiology-wait and documentation-rework leaks tend to dominate, accounting together for perhaps 15-20% of the shift. In surgery, the pattern shifts — the largest leak is typically OR-turnover and preoperative-assessment waiting, with documentation rework running lower because surgical documentation has more structured templates. In emergency medicine, the hunting-for-information leak dominates — paging, locating specialists, chasing results from outside systems can consume 8-12% of the shift on a busy day. In intensive care, system-switching and handover documentation are the largest consumers. Every specialty has the five leaks; the proportions differ.

What does not differ is the underlying principle. The time consumed by these five leaks is not time spent caring for patients. It is time spent on friction introduced by the hospital’s own architecture. That time cannot be reclaimed by asking physicians to work faster. It can only be reclaimed by redesigning the architecture that is consuming it.

What the Schlüchtern PRIME work showed.

At Main-Kinzig-Kliniken Schlüchtern, the geriatric department commissioned a structured shadow study of consultant and registrar time in late 2019 as part of the broader operational restructuring. The study ran for fifteen working days, covered both ward and ambulatory rotation patterns, and was framed explicitly to participating physicians as an operational audit of the department’s own processes rather than a performance review of the individuals. The findings surfaced the five leaks with an aggregate of approximately 31% of the working shift — within the range that subsequent engagements across other specialties have since reproduced.

The remediation work ran across eighteen months, with different leaks owned by different cross-functional leads. Radiology turnaround improved through a redesigned request-triage protocol. Documentation rework dropped substantially with the installation of the concurrent-coding rhythm described in Post 15 of this series. System-switching time fell with a consolidated single-sign-on rollout. The combined operational effect, sustained under the research programme with Prof. Dr. Rainer Sibbel at Frankfurt School [1,2], contributed measurably to the department’s broader transformation; PRIME-layer improvements do not stand alone but amplify the FLOW and CAPTURE work that sits adjacent to them.

What to do on Monday.

If you lead a hospital or department where the conversation about physician productivity has been gaining intensity, there is a specific first move that costs very little and changes the conversation substantially.

Commission a fifteen-day structured observation of consultant and registrar working shifts in the department in question. Frame it explicitly, in writing, to participating clinicians: this is an audit of the hospital’s architecture, not of the individuals. Document time allocation in fifteen-minute blocks against a standard category list that includes the five leaks above. The observation can be done by an internal operational analyst or by an external structured-observation specialist; the key is methodological consistency across the fifteen days, not who performs the observation.

At the end of the fifteen days, compile the distribution. The five leaks will surface with specific proportions. Present the findings to the joint leadership of medical directorate, nursing, radiology, IT, and controlling in one room. The conversation that follows is different from any conversation the same leadership team has had before, because it is grounded in specific operational data rather than in disagreement about effort and intention.

Assign each of the five leaks to a named cross-functional owner with a 90-day and 180-day target. The ownership is what converts the observation into structural change. A leak that is identified but unowned remains a leak; a leak that is owned, tracked, and quarterly-reviewed closes.

And do not, under any circumstances, present the shadow study’s findings back to physicians in a way that makes them seem like the source of the leaks. The physicians have been bleeding time. They are the ones who will most appreciate the hospital taking the time leak seriously, and who will be the most supportive of structural remediation. Handled well, the PRIME-layer conversation is a retention conversation as much as a productivity one.

The hospital that runs a PRIME-layer hunt produces specific, named, closeable leaks every time. The hospital that relies on performance judgment produces defensive clinicians and no operational change. These two organisations are not at different points on a spectrum. They are operating in different categories.

Hunt the leaks. Trust the clinicians. That is the whole PRIME layer in two sentences.
