The structure of American medicine has changed profoundly over the past several decades. To understand the role of concierge medicine today—and where it may be going—it is useful to remember how physicians once practiced.
For much of the twentieth century, hospitals and physicians existed in a relationship of mutual dependence while remaining largely independent of one another. A private physician might spend an entire career closely affiliated with a particular hospital, admit patients there, participate in its medical staff, teach its trainees, and even hold leadership positions, while continuing to own and operate an independent medical practice.
The hospital was where the physician practiced. It was not necessarily the organization for which the physician worked.
This distinction mattered.
The physician’s relationship with the patient extended across settings. An internist might care for a patient in the office, admit that patient to the hospital when illness developed, select the consultants he or she considered most appropriate, remain involved throughout the hospitalization, and resume care after discharge. The hospital supplied increasingly sophisticated institutional resources, but the physician remained the patient’s personal doctor.
Beginning with the growth of managed care, this structure gradually changed. Physician organizations emerged to negotiate with insurers, manage risk, coordinate networks, and provide administrative infrastructure that individual practices could no longer easily provide themselves. In many respects, these organizations initially represented a reasonable compromise: physicians could remain independent while participating collectively in an increasingly complex healthcare economy.
Over time, however, integration progressed further.
Physician organizations became increasingly intertwined with health systems. Hospitals acquired practices. Physicians increasingly became employees. Referral networks became more organized. Electronic health records, quality programs, population-health initiatives, productivity measures, and payer contracts became centralized.
Today, a young physician entering practice may spend an entire career within a large healthcare organization. Clinical decisions remain the responsibility of physicians, but many aspects of professional life—appointment length, staffing, scheduling, referral pathways, productivity expectations, information systems, and administrative priorities—are determined by the institution.
This evolution has brought substantial benefits. Modern health systems can provide extraordinary technological capabilities, multidisciplinary care, sophisticated quality infrastructure, and access to expertise that would have been unimaginable a generation ago.
But something has also been lost.
Who Represents the Patient?
Large health systems are designed to deliver healthcare to populations. They must balance the interests of patients, physicians, employees, insurers, regulators, and the financial sustainability of the institution itself.
The individual patient has a different problem.
A patient does not experience healthcare as an organizational chart. A patient may have a cardiologist at one hospital, a surgeon at another, an oncologist at a specialized cancer center, imaging performed elsewhere, and perhaps medical care in another state for part of the year.
Each specialist may provide excellent care within his or her field. Each institution may provide outstanding services.
But someone still needs to answer the larger question:
What is right for this particular person?
That question becomes increasingly important as medicine becomes more sophisticated.
More testing does not necessarily create greater clarity. Advanced imaging, molecular diagnostics, genetic testing, biomarkers, wearable devices, and artificial intelligence generate an extraordinary amount of information. Specialists appropriately view problems through the lens of their expertise. Clinical guidelines provide essential evidence, but guidelines are necessarily designed around populations.
The patient, however, is not a population.
The patient is an individual with a particular medical history, physiology, family, priorities, tolerance for risk, and definition of a meaningful life.
Someone must synthesize all of this.
I believe that is one of the most important responsibilities of a personal physician.
Independence Has Clinical Value
Independence in medicine is sometimes discussed primarily as a professional or economic issue for physicians. I believe it also has value for patients.
An independent physician is not defined by opposition to health systems. Quite the contrary. The great academic medical centers represent some of the finest achievements of modern medicine, and their expertise is indispensable.
But no single institution possesses every answer.
The role of an independent physician is therefore not to compete with these institutions, but to help the patient use them wisely.
For one problem, the right specialist may be at Mass General. For another, it may be at Brigham and Women’s, Beth Israel Deaconess, Dana-Farber, or another institution entirely. Occasionally, the best answer may be found outside Boston.
The starting question should not be:
“Who within my system should see this patient?”
It should be:
“Who is the right physician for this patient?”
That distinction may appear small, but I believe it represents an important form of clinical independence.
Concierge Medicine Is Not Primarily About Convenience
Concierge medicine is often described in terms of its amenities: easier appointments, longer visits, direct communication with the physician, and greater availability.
These are valuable. But they are not, in my view, the fundamental purpose of the model.
Time is valuable because good medicine requires time.
Accessibility is valuable because illness does not always conform to an appointment schedule.
A smaller patient panel is valuable because knowing a person over many years changes the quality of medical judgment.
The membership model is therefore not the philosophy. It is the economic structure that makes the philosophy possible.
Traditional high-volume primary care increasingly requires physicians to care for very large panels while simultaneously managing extensive documentation, electronic messages, quality requirements, and administrative responsibilities. Even excellent physicians can struggle to provide the depth of attention that complex medical decision-making requires.
A smaller practice creates something increasingly scarce in modern healthcare: the ability to think.
It allows the physician to review a complicated history before the visit, speak with a specialist personally, examine the evidence behind a recommendation, discuss uncertainty with the patient, and continue thinking about a problem after the patient has left the office.
That is not luxury medicine.
That is how I believe medicine should be practiced.
From Gatekeeper to Medical Strategist
The traditional primary-care physician was sometimes described as a gatekeeper. I believe the physician of the future should instead function as a medical strategist.
The distinction is important.
A gatekeeper controls access to resources.
A medical strategist determines how resources should be used.
Modern patients have access to extraordinary medical capabilities. The challenge is increasingly deciding which capabilities matter, when to use them, when not to use them, and how to reconcile conflicting recommendations.
For a healthy person, this means thinking carefully about prevention—not simply ordering every available test, but identifying meaningful risks early and intervening where evidence and clinical judgment suggest that doing so can preserve health, function, and independence.
For someone with complex illness, it means seeing the entire person rather than a collection of organ systems. Kidney disease affects cardiovascular decisions. Frailty changes the balance between intervention and observation. Medications prescribed for one condition can worsen another. A technically successful procedure is not necessarily a successful outcome if it does not improve the patient’s overall health or quality of life.
The personal physician must maintain this broader perspective.
The Model Alone Is Not Enough
A smaller practice and greater physician availability can create the conditions for highly personalized medicine. But they do not, by themselves, create the expertise required to practice it.
The value of an independent personal physician ultimately depends on the physician.
To advise a patient across specialties and institutions requires more than accessibility. It requires broad clinical knowledge, deep experience with serious and complex illness, the ability to recognize when a problem exceeds one’s own expertise, and the judgment to identify which specialist or institution is best suited to address it.
Much of this judgment is accumulated over decades.
Years spent caring for patients with difficult illnesses, working alongside specialists across disciplines, observing the consequences of both intervention and restraint, and following patients through periods of health, illness, hospitalization, recovery, and aging create a form of clinical perspective that cannot be acquired quickly.
Credentials alone are not sufficient either. Academic training and subspecialty expertise are valuable because they deepen the physician’s understanding of evidence and disease. But the personal physician must also be able to step outside the boundaries of a single specialty and see the patient as a whole.
This combination is uncommon:
Breadth without superficiality.
Depth without tunnel vision.
Experience without rigidity.
It also requires professional humility. The independent physician does not need to possess every answer. The physician needs to know which questions matter, recognize uncertainty, understand when additional expertise is necessary, and know where to find it.
This is particularly important when serving as a patient’s medical strategist. Recommending a specialist is easy. Determining which specialist is appropriate, evaluating that specialist’s recommendation in the context of the patient’s other conditions and priorities, and helping the patient decide whether to proceed requires a different level of judgment.
For this reason, I do not believe concierge medicine should be defined simply by panel size, membership fees, or physician availability.
Those are characteristics of a practice model.
True personalized medicine depends on the caliber, experience, judgment, and independence of the physician practicing within that model.
The membership structure creates time.
Independence creates freedom.
Experience creates judgment.
Relationship creates understanding.
Together, these make truly personalized medicine possible.
Technology Should Strengthen, Not Replace, the Physician Relationship
Artificial intelligence will accelerate these changes.
AI will increasingly summarize medical records, identify abnormalities, review scientific literature, detect preventive-care gaps, and assist with diagnostic reasoning. Many tasks that currently consume physicians’ time will eventually become substantially automated.
I welcome this development.
The purpose of medicine is not to preserve tasks for physicians that machines can perform better.
But as information becomes abundant, judgment becomes more important, not less.
The difficult questions in medicine are rarely simply questions of information.
Should an 82-year-old undergo this operation?
Does an abnormal finding justify another invasive procedure?
Which of several reasonable treatments best fits this person’s priorities?
When specialists disagree, whose recommendation should carry greater weight?
When should we intervene—and when should we leave something alone?
Artificial intelligence can inform these decisions. Specialists can contribute their expertise. Guidelines can define the evidence.
But ultimately someone must know the patient well enough to integrate them.
The future personal physician should use technology aggressively while preserving something technology cannot easily reproduce: longitudinal responsibility for another human being’s health.
A Modern Return to an Old Idea
In some ways, this philosophy represents a return to an older model of medicine.
The independent physician once stood between the patient and the hospital. The physician knew the patient personally and brought the resources of the hospital to bear when they were needed.
Modern medicine cannot—and should not—return to the healthcare system of forty years ago. Today’s medicine is far more sophisticated. Hospitalists, integrated electronic records, multidisciplinary teams, advanced imaging, molecular diagnostics, and highly specialized tertiary centers have transformed what physicians can accomplish.
The opportunity is to combine the best elements of both eras.
We can preserve the extraordinary capabilities of modern health systems while restoring the independence, continuity, and personal accountability of the traditional physician-patient relationship.
The hospital does not need to be the patient’s medical home.
Neither does an insurance company, an electronic health record, or a healthcare corporation.
The relationship with a trusted physician can be the medical home.
That physician can then help the patient navigate institutions rather than asking the patient to navigate them alone.
This is how I view the future of concierge medicine.
It is not medicine separated from the healthcare system.
It is a physician standing beside the patient within an increasingly complicated healthcare system—bringing together evidence, technology, specialists, institutions, and decades of clinical experience while remaining focused on one fundamental question:
What is best for this person?
