What is the hospital optimized for?
Modern medicine is extraordinary. Yet hospital process efficiency has not always advanced at the same pace. We can look inside the human body with remarkable precision, monitor complex systems in real time, analyze blood chemistry in minutes, perform procedures that would have seemed impossible a generation ago, and bring together specialists from multiple disciplines to solve difficult medical problems.
And yet the process connecting all of that extraordinary medicine can still feel surprisingly ordinary.
Wait here. Move there. Sit in this room. Someone will come eventually.
Over the past week, I have spent roughly six days in a hospital, preceded by another six-hour visit to the emergency department. By my rough calculation, perhaps four hours of that time involved actual tests, procedures, examinations, or substantive consultations with physicians. The rest—well over 100 hours—has largely been spent waiting for the next part of the system to become ready.
The tests were appropriate. The medical questions were legitimate. I am not suggesting that physicians should rush important decisions simply because patients are tired of waiting.
But after spending this much time observing the system from the inside, I keep coming back to a simple question:
What exactly is the hospital optimized for?
Extraordinary Medicine, Ordinary Process Problems
My first encounter was a six-hour visit to the emergency department. During that time, I had bloodwork and a CT scan. Both were appropriate and necessary. What struck me was how much of the remaining time consisted simply of waiting.
At one point, I was transferred to a fast-track area and placed alone in a small cubicle while my wife remained elsewhere. No test was performed there. No physician came in. Nothing that I could see was happening.
After more than an hour, I finally got up and asked whether I could simply return to the waiting area and sit with my wife. The answer was yes.
That small episode stayed with me because it seemed to capture something much larger. There may have been a perfectly sensible reason for moving me into that cubicle. Perhaps it fit an established workflow for moving patients through the emergency department. Yet if I could safely sit there alone without monitoring, treatment, or examination, it was difficult to understand why I could not spend the same hour sitting with my wife.
Several days later, I was admitted for further evaluation of a medical problem that might have required a procedure. Six days later, I am still here.
During that time, I have undergone imaging, laboratory tests, examinations, and consultations with several physicians and specialists. All of that matters. Doctors also review images, discuss cases, consult with one another, and make decisions outside the patient’s room, so it would be unfair to suggest that nothing is happening simply because I cannot see it.
But the imbalance remains remarkable: roughly 144 hours in the hospital compared with perhaps four hours of direct medical activity.
That is an extraordinary amount of infrastructure, time, inconvenience, and expense surrounding a relatively small amount of actual interaction with the medical system.
The Patient Becomes the Buffer
Hospitals undoubtedly optimize enormous numbers of individual processes. Imaging departments schedule expensive equipment. Laboratories process samples. Nurses manage multiple patients. Specialists organize rounds, consultations, procedures, and operating schedules. Administrators manage staffing and beds.
Each part of the hospital may be operating quite rationally on its own.
The problem is that optimizing individual components does not necessarily optimize the patient’s journey through the system. If imaging cannot happen until tomorrow, the patient waits. If a specialist cannot review the results until later, the patient waits again. If another consultation is required after that, another cycle begins.
The patient’s time becomes the buffer between all of those separately organized processes.
In almost any other industry, that would immediately be recognized as an operations problem. Airlines measure aircraft utilization. Factories measure downtime. Logistics companies optimize routes and delivery windows. Software companies measure latency in milliseconds. Retailers spend enormous amounts of money eliminating friction between a customer’s decision to buy something and receiving it.
Healthcare is obviously different. Patients are not packages moving through a fulfillment center, and clinical safety must come first. Medical conditions change. Emergencies disrupt schedules. Diagnosis involves uncertainty. Sometimes the correct decision really is to watch, wait, and gather more information.
But complexity should not exempt a system from asking whether the time between medically necessary activities can be designed better.
The remarkable thing may not be how much medicine happens inside a hospital. It may be how much hospitalization happens between the medicine.
The Weekend Makes the Problem Visible
The contrast became especially noticeable over the weekend.
Very little happened on Saturday or Sunday. There were occasional visits and routine care, but the pace of evaluation and decision-making slowed dramatically. That is understandable. Physicians and specialists have lives outside the hospital. They go home, sleep in their own beds, eat their own food, and return according to their schedules.
The patient, however, remains hospitalized continuously through that same period.
That is not a criticism of doctors for going home. Of course they should. It is a question about system design.
If the diagnostic and decision-making process slows substantially for 48 hours, what function is the hospital serving for a medically stable patient during those same 48 hours? If continuous hospitalization is necessary because of a meaningful medical risk, that is entirely reasonable. But if the principal reason for remaining is simply that the process will resume more fully on Monday, then the patient is absorbing the downtime of the institution.
After nearly a week, even relatively small inconveniences begin to accumulate. Sleep is repeatedly interrupted. Ordinary routines disappear. Privacy and independence are reduced. Meals arrive according to the institution’s schedule and, in my experience, frequently have little resemblance to what I actually ordered.
None of those issues is remotely as important as receiving safe medical care. But that does not mean they have no value.
When the System Is Ready, the Patient Must Be Ready
The hospital’s control of time also affects something more important than comfort: the ability of the patient to participate intelligently in his or her own care.
At about 5:30 one morning, a specialist came into my room with one of the most consequential updates of the hospitalization. I had been asleep. Within moments, I was trying to wake up, understand what I was being told, process a significant change in the treatment plan, and formulate questions about what should happen next.
There may be excellent reasons physicians make rounds at 5:30 in the morning. Hospitals operate around complicated schedules, and specialists have many competing responsibilities.
But it raises a revealing question. Is an important medical conversation scheduled around when the system can most efficiently deliver the information, or when the patient is best able to receive and understand it?
That is more than a hospitality issue. The patient is supposed to understand alternatives, ask questions, participate in decisions, and provide informed consent. Attention and comprehension are part of the medical process itself.
A system that improves physician scheduling while reducing the patient’s ability to understand an important conversation may be optimizing one part of the process at the expense of another.
The Cost Is More Than the Hospital Bed
Healthcare costs are notoriously difficult for patients to understand, and I do not yet know what the financial cost of these six days will ultimately be. But whatever appears on a hospital or insurance statement captures only part of the expense.
There is the value of the patient’s time and lost productivity. There is disrupted sleep and the temporary surrender of ordinary independence. There is also the burden placed on family members.
My wife lives about 45 minutes from the hospital. Every visit therefore involves roughly an hour and a half of driving before accounting for the time she spends here. Multiply that across several days, and hospitalization consumes far more than the patient’s own time.
None of these costs should override medical safety. But they should not automatically be assigned a value of zero either.
If a patient needs continuous observation, immediate access to specialists, or the possibility of rapid intervention, an inpatient hospital bed may be exactly where that person belongs. If that is the case, the reason for continued hospitalization should also be understandable to the patient.
If the patient is primarily waiting for the next test, consultation, or decision, it is reasonable to ask whether the most expensive and restrictive setting in healthcare is always the best place to wait.
What Would We Design If We Started Over?
Suppose we were designing the hospital experience from scratch rather than inheriting the systems and workflows that already exist.
Safety and clinical outcomes would obviously come first. But we would probably add other objectives as well: minimize unnecessary waiting between medically necessary activities, use the least intensive safe setting for each stage of care, preserve inpatient beds for patients who truly require inpatient resources, maximize patient independence whenever medically appropriate, and consider the time and burden imposed on families.
We might also give patients much greater visibility into the process.
What are we waiting for? When is it expected to happen? Why do I need to remain physically in the hospital while we wait? What medical risk is being managed by keeping me here? What would need to change before this process could continue somewhere else?
Those are ordinary questions in operations management. They should not be extraordinary questions in healthcare.
There may also be far more opportunity between the two choices patients often face. At one end is outpatient medicine, where tests and specialist appointments may unfold over days or weeks. At the other is hospitalization, where the diagnostic process can move faster but the patient may occupy an inpatient bed continuously while waiting for each successive part of the process.
Perhaps the more interesting innovation is somewhere between those extremes.
Extraordinary Medicine Deserves an Extraordinary Process
My experience may not be representative. It may reflect the particular medical issue being evaluated, the workings of one hospital, unusual circumstances, or perfectly legitimate clinical considerations that are not obvious from the patient’s side of the bed.
But that uncertainty does not make the underlying question less important.
Modern healthcare contains some of the most sophisticated technology and highly trained professionals in the world. The ability to diagnose and treat disease has advanced enormously. Yet from the patient’s perspective, the process connecting those extraordinary capabilities can still consist of surprisingly long periods of waiting, uncertainty, interruption, and loss of control.
Everyone involved may be doing his or her individual job correctly while the overall system still produces an inefficient result. That is often how systemic problems work.
We have spent decades developing extraordinary technologies for diagnosing and treating disease. We will continue to develop better imaging, better drugs, better procedures, better artificial intelligence, and better ways of understanding the human body.
Perhaps one of the next important innovations in healthcare will be considerably less glamorous.
It may simply be designing the time between them.
