Physician

Last updated

Physicians diagnose and treat illness, injury, and disease — taking patient histories, performing physical examinations, ordering and interpreting diagnostic studies, prescribing treatments, and coordinating care across specialties and settings. The physician career encompasses primary care generalists and dozens of specialty and subspecialty tracks, with compensation, lifestyle, and daily practice varying considerably across the spectrum.

Duties and responsibilities

  • Obtain detailed patient histories — presenting complaint, history of present illness, past medical and surgical history, medications, social and family history
  • Perform physical examinations, applying clinical findings to develop a differential diagnosis and treatment plan
  • Order and interpret laboratory tests, imaging studies, and diagnostic procedures, integrating results into clinical decision-making
  • Prescribe medications, therapies, and interventions appropriate to the diagnosis, weighing efficacy against risks and patient preferences
  • Perform procedures within scope of specialty practice — ranging from in-office biopsies and injections to complex operative interventions
  • Coordinate care with specialists, subspecialists, other clinicians, and community resources to ensure patients' needs are met across settings
  • Document patient encounters in the electronic health record, maintaining accurate and timely clinical notes, orders, and discharge summaries
  • Participate in quality improvement, peer review, and clinical performance programs required by hospitals and payers
  • Counsel patients on preventive health, chronic disease management, and the behavioral determinants of their conditions
  • Maintain board certification and continuing medical education requirements, staying current with evidence-based practice in the specialty

Overview

Physicians are responsible for diagnosis and treatment — the two activities that sit at the top of the clinical hierarchy and require the most extensive training to perform independently. Every other healthcare profession either supports physician decision-making, executes physician-directed care, or practices within a defined scope that explicitly excludes the physician's core functions.

What that looks like in practice depends entirely on specialty. A family physician in a solo practice in rural Montana sees 20–25 patients per day across the full spectrum of primary care — well child visits, diabetes management, upper respiratory infections, mental health, prenatal care, fracture management — and admits patients to the local critical access hospital on nights and weekends. A neurosurgeon in a major academic medical center performs 8–12 complex spine or cranial operations per week, rounds on post-operative patients with a resident team, and sees new consultations in a clinic squeezed between operative days.

The common thread is clinical judgment. Medicine is not a rule-following profession — it is a judgment profession. The physical examination findings, the lab values, the history, the imaging, the patient's stated goals, and the physician's clinical experience all have to be integrated into a decision about what to do next, and that decision has to be communicated to the patient clearly enough that they understand and can participate in making it. That communication dimension — breaking difficult news, explaining uncertain diagnoses, navigating treatment disagreements — takes as much skill as the technical clinical work and is less well trained in medical education.

The administrative burden on physicians has grown to the point where it is a leading driver of career dissatisfaction. Prior authorization for medications, procedures, and imaging, quality metric reporting, documentation requirements for CMS and private insurers, and the time demanded by the EHR have expanded the non-clinical time component of physician practice substantially. Time-motion studies consistently show that physicians spend more than 50% of their working time on documentation and administrative tasks.

Qualifications

Education and training:

  • Bachelor's degree with required premed prerequisites (biology, chemistry, organic chemistry, physics, biochemistry, math)
  • MCAT (Medical College Admissions Test) — competitive scores are essential for allopathic (MD) school admission
  • Medical school: 4 years — 2 preclinical (coursework) + 2 clinical (rotations across major specialties)
  • USMLE Step 1, Step 2 CK licensing exams during medical school (required for graduation and residency application)
  • Residency via NRMP Match: 3–7 years depending on specialty
  • Fellowship (optional, or required for subspecialty): 1–3 additional years

Licensure:

  • MD or DO degree
  • USMLE or COMLEX board exam passage (Step 1, Step 2, Step 3)
  • State medical license

  • Hospital privileges for physicians with inpatient or procedural practice

Board certification:

  • Specialty board certification through the relevant certifying board (ABIM, ABFM, ABS, ABP, etc.)
  • Maintenance of Certification (MOC) requirements every 5–10 years depending on specialty board

Core clinical competencies across all specialties:

  • History taking: efficient, systematic, and patient-centered
  • Physical examination: reliable and reproducible findings that inform differential diagnosis
  • Clinical reasoning: hypothesis generation and narrowing under uncertainty
  • Diagnostic interpretation: integrating labs, imaging, pathology, and functional studies
  • Procedural skills: specialty-specific, ranging from routine office procedures to complex operative techniques
  • Pharmacology: prescribing decisions, drug interactions, monitoring requirements

Career outlook

Physician demand in the U.S. is projected to exceed physician supply significantly over the next decade. The AAMC's most recent workforce projections estimate shortfalls of 37,000–124,000 physicians by 2034, driven by population growth and aging, expanding covered populations, and retirement attrition among the physician workforce itself — the average physician age has been rising steadily.

The geographic distribution problem is severe and worsening. Rural and small-town America has physician shortages in most primary care and many specialty fields that no amount of aggregate physician supply growth will fully address without deliberate policy and incentive programs. The Health Professional Shortage Area (HPSA) designation system and NHSC scholarship and loan repayment programs exist specifically to create financial incentives for practice in underserved areas.

Specialty-level demand varies considerably. Primary care has the broadest documented shortage and the largest geographic maldistribution problem. Psychiatry faces a crisis-level shortage driven by inadequate training capacity relative to the mental health epidemic. Dermatology, ophthalmology, and urology are in tight supply in smaller markets. Surgical specialties face different pressures: procedure volume growth in joint replacement, cardiac surgery, and minimally invasive procedures creates demand, while consolidation of procedures into centers of excellence reduces the number of sites where less experienced surgeons can maintain volume.

The most significant structural change in physician practice is consolidation. Independent physician practice has declined from over 50% of all physicians in 2012 to well below 40% today. Large health systems, private equity groups, and health insurance companies have acquired physician practices at a rapid pace. For physicians entering practice, the employment model is now the dominant reality rather than a niche option, and understanding how to negotiate employment contracts, production bonus structures, and non-compete agreements has become a practical clinical training gap.

Despite compensation compression relative to older generations of physicians — higher medical school debt, lower starting salaries adjusted for inflation, higher overhead costs in independent practice — physician compensation remains among the highest in any profession, and the career remains one of genuine meaning and societal impact.

Sample cover letter

Dear Department Chair,

I am writing to apply for the Internal Medicine Hospitalist position at [Medical Center]. I complete my Internal Medicine residency at [Program] in June, where I have served as Chief Resident for the past year.

My training has been at a large academic medical center with high-acuity inpatient medicine volume. My clinical interests are in complex medical management — patients with multiple comorbidities, difficult diagnostic cases, and the challenging transitions between acute care and the next level of care. Chief year has expanded my exposure to operational and quality improvement work, and I've led a project reducing 30-day readmissions in our heart failure population through a standardized discharge checklist and scheduled post-discharge follow-up calls.

I'm specifically interested in hospitalist medicine because I find the inpatient environment intellectually engaging — the diagnostic breadth, the pace, and the opportunity to work closely with subspecialty consultants across every rotation. I've deliberately sought the most challenging admissions throughout residency, and I've developed comfort with the uncertainty that goes with a diagnostic presentation that doesn't resolve on the first day.

On the teaching side, I've supervised and evaluated third-year medical students and interns throughout residency, and I genuinely enjoy that part of the work. A program with a robust teaching mission is where I want to practice.

[Medical Center]'s volume, case mix, and academic affiliation are exactly what I'm looking for. I would welcome the opportunity to speak with you about the position.

Sincerely, [Your Name], MD

Frequently asked questions

What is the difference between an MD and a DO?
MDs (Medical Doctors) and DOs (Doctors of Osteopathic Medicine) are both fully licensed physicians who complete medical school, residency, and board certification. DOs receive additional training in osteopathic manipulative medicine (OMM) and have a whole-person philosophy emphasis in their training. In practice, MDs and DOs practice in the same hospitals, compete for the same residency programs, and are licensed identically by state medical boards. The distinction is primarily one of philosophy and training lineage, not clinical scope or practice quality.
How long does it take to become a physician?
After a four-year bachelor's degree, medical school is four years (preclinical and clinical rotations). Residency training after medical school ranges from 3 years (family medicine, internal medicine, pediatrics) to 7+ years (neurosurgery, plastic surgery). Fellowship training in subspecialties adds 1–3 additional years after residency. Total physician training from college entry typically runs 11–18 years depending on specialty.
What is the difference between a hospitalist and an outpatient physician?
Hospitalists are physicians (typically internal medicine or family medicine trained) who provide inpatient care exclusively — managing patients from admission to discharge in the hospital. They do not have their own outpatient panels. Outpatient primary care physicians manage patients in clinic settings and coordinate hospital care with hospitalists when their patients are admitted. Many health systems have moved to this split model because it allows both hospitalists and outpatient physicians to focus on their respective environments.
How is physician burnout affecting healthcare?
Physician burnout is at historically high levels, driven by administrative burden (documentation, prior authorization, quality metric compliance), electronic health record demands, loss of practice autonomy through consolidation, and the accumulated stress of high-stakes patient care. More than half of physicians report symptoms of burnout in survey data. The consequences include premature retirement, reduction in clinical hours, and career transitions out of patient care. Healthcare systems are increasingly investing in burnout reduction as a retention and quality issue.
How are nurse practitioners and physician assistants changing physician practice?
Advanced practice providers (APPs) — nurse practitioners and physician assistants — have taken on more clinical responsibilities as their scope of practice has expanded in many states. In primary care and some specialty settings, APPs handle significant patient volumes that would previously have required physician time. For physicians, this creates a supervisory and collaborative dimension; for patients and health systems, it improves access. The physician's role in team-based care has shifted toward higher-complexity cases and oversight of APP-managed patient panels.
