Becoming an “N of 1” in a System Built for the Many

Dr. Arthur Lazarus writes about how true healthcare reform does not require dismantling medicine but reorienting it so that systems serve populations while remembering that every patient experiences illness as an irreducible “n of 1.”

From/about the article: Becoming an n of 1 is not about rejecting medicine. It is about resisting the reduction of patients to denominators.

One of the most influential books I ever read was The Success Principle by business professor Ronald N. Yeaple. Published in 1997, it offered a deceptively simple roadmap for career success: become an “n of 1.”

In statistical language, an n of 1 is a sample size of one. In Yeaple’s formulation, it meant something more radical. It meant becoming the CEO of your own enterprise. Your core competencies report to you. You report to your board of mentors. You are not a passive employee of circumstance. You are the architect of your outcomes.

For years, that idea was firmly planted in the background of my professional life as a physician. Medicine, after all, does not train us to be n of 1. It trains us to think in populations, probabilities, protocols, and pathways. We serve the many. We triage. We standardize. We respond.

Recently, a physician took a different path. He wrote on LinkedIn:

“I would not trust any doctor or department in traditional healthcare to care for a member of my family. As a physician, it’s a hard thing to admit. But it is the reality of the system we have built.”

He went on to describe a flipped healthcare model: 90-minute visits instead of 15-minute encounters. Hunting biomarkers instead of waiting for symptoms. Engineering performance rather than treating disease. He concluded with a line that echoes Yeaple’s thesis almost verbatim: You should feel like the CEO of your own health outcome.

The readers’ reactions were swift and revealing.

Some applauded the boldness. Others pointed out the obvious: 90-minute preventive biomarker hunts work best for people who can afford cash-based care and who are not acutely ill. That is curation, not system redesign. Several noted that the real constraint is incentive design. Fee-for-service rewards intervention, not prevention. Structure shapes behavior. Or, as I was taught in business school, form follows function.

Rock your Course

 

A primary care physician asked a simple, genuine question: why is a doctor working in a federally qualified health center less trustworthy? Another reminded us kindly that reactive care is not inferior care. Some of us like it. Patients are grateful for it. There is room enough for everyone in the tent.

And someone else said something that stopped me: if you want to build an ecosystem that delivers an intended result, good luck, you will likely succeed. But perhaps what you are describing is not “doctoring” at all. Perhaps it is a new discipline waiting to be codified and legitimized. Medicine, as we know it, is grounded in Flexnerian reform and Oslerian bedside principles. That foundation exists regardless of incentives.

The tension in that thread is not about trustworthiness. It is about identity.

Traditional medicine, rooted in the curricula reforms of Abraham Flexner and the bedside philosophy of William Osler, is built to respond to illness. It waits for the crash because historically that is when patients appeared for treatment. It developed antibiotics, trauma surgery, coronary care units, ventilators. It became very, very good at rescue.

 

Some of the best healthcare voices are hiding in plain sight. Our speaker directory helps you find them, follow them, and invite them into the conversations that need them.

 

Rescue is reactive by definition. And it is honorable work.

But Yeaple’s n of 1 challenges us to think differently. Not about abandoning rescue but about ownership, owning your destination.

The uncomfortable truth is that physicians already behave as n of 1 actors in their own lives. We research our own symptoms differently. We leverage our networks differently. We ask for second opinions. We optimize. We curate. We convene our own informal “board of mentors” when our families are involved.

That discrepancy is what unsettles people. Not incompetence. Not malice. But structure.

The current system is optimized for automation and intervention. Fifteen-minute visits are not operations failing; they are a scheduling artifact of reimbursement. Reactive care is not evidence of indifference; it is what the system pays for.

So, what happens when a physician says, “I would not trust this system for my family”?

It feels like betrayal. But it may actually be confession.

The system we built incrementally, rationally, with good intentions rewards acute intervention over longitudinal optimization. It values measurable episodes over invisible prevention. It reimburses procedures more reliably than conversations. Under those rules, reactive care is not a choice; it is a calling.

The proposed “CEO of your health” model attempts to escape that calling.

But here is the caution: being an n of 1 works beautifully for individuals with resources. It is more difficult to scale, however, across millions of people with variable literacy, income, and time. When preventive biomarker panels become boutique offerings, we risk creating a two-tiered narrative, one optimized, one stabilized.

And yet, dismissing the aspiration would be equally shortsighted.

There is wisdom in encouraging patients to see themselves as active stewards of their health. There is wisdom in longer visits, in deeper listening, in searching upstream for metabolic drift before catastrophe. There is wisdom in reimagining incentives that reward long-term outcomes instead of episodic intervention.

But there is also wisdom in defending the dignity of reactive care. The emergency physician who stabilizes a ruptured aneurysm at 2 a.m. is not practicing obsolete medicine. The internist managing decompensated heart failure in a safety-net hospital is not less visionary. They are practicing medicine as it has always existed: at the edge of human vulnerability.

Perhaps the real insight is this: medicine is population-based by necessity, but health is always lived as an n of 1 experience. Patients feel singular. Illness affects individuals. Healthcare encounters are personal.

The future likely requires the coexistence of both disciplines, the Oslerian rescuer and the yet-to-be-codified performance engineer. The acute stabilizer and the longitudinal optimizer. The physician grounded in tradition and the innovator building alternative ecosystems.

 

 

If you want to design a new educational pathway for proactive health architects, lead on. Codify it. Standardize it. Subject it to evidence. But do not denigrate the clinicians who continue to do the reactive work. There is room enough for both.

Yeaple’s lesson was not that everyone must disregard institutional hierarchy. It was that individuals must take responsibility for their trajectory. In health care, that may mean something more modest and more powerful: patients as engaged participants, physicians as accountable stewards, systems that align incentives with prevention without forgoing rescue.

Medicine may operate on cohorts, but care must land on individuals. Every patient experiences disease as an n of 1 event. No one feels like an average.

Becoming an n of 1 is not about rejecting medicine. It is about resisting the reduction of patients to denominators.

 

The system we built incrementally, rationally, with good intentions rewards acute intervention over longitudinal optimization. It values measurable episodes over invisible prevention.
