Doctors who work the fewest hours tend to be in specialties like dermatology, psychiatry, ophthalmology, pathology, and allergy/immunology, most of which average around 40 to 50 hours per week. That’s notably less than surgical specialties, where 60-plus-hour weeks are common. The gap comes down to practice setting, on-call demands, and whether the specialty involves emergencies.
Specialties With the Lightest Schedules
Stanford Medicine’s guide to choosing a specialty specifically names radiology, dermatology, pathology, emergency medicine, anesthesia, ophthalmology, physical medicine and rehabilitation (PM&R), and neurology as fields where physicians have more control over their hours. Several of these consistently land at the lower end of work-hour surveys.
Dermatology is one of the most commonly cited low-hours specialties. Most dermatologists work in outpatient clinics with predictable schedules, rarely take overnight call, and almost never handle life-threatening emergencies. A typical workweek falls between 40 and 50 hours, and part-time arrangements are relatively easy to find. The field’s emphasis on scheduled appointments rather than acute care makes this flexibility possible.
Psychiatry is another specialty with lighter-than-average hours. Many psychiatrists work in private practice or outpatient settings and set their own schedules. Some work far fewer hours than a traditional full-time physician. At one large New York health system, psychiatrists on per diem schedules averaged just 14 hours per week in 2023. While that reflects a specific staffing model and not the national average, it illustrates how much schedule flexibility the field allows. Psychiatrists who do work full-time typically log 40 to 50 hours weekly, still well below the physician average.
Pathology and radiology both involve diagnostic work rather than direct patient encounters. Pathologists examine tissue samples and lab results; radiologists interpret imaging studies. Neither specialty involves traditional office visits, and while both may have some on-call responsibilities, they rarely deal with the unpredictable scheduling that surgical or hospital-based specialties face. Both average roughly 45 to 50 hours per week for full-time physicians.
Ophthalmology and allergy/immunology round out the lower end. Both are outpatient-heavy, procedure-oriented specialties with minimal emergency call. Allergists in particular tend to keep standard business hours, and ophthalmologists, while they may take occasional call for eye emergencies, generally maintain predictable clinic schedules.
Emergency Medicine: Fewer Hours, Higher Intensity
Emergency medicine deserves its own category. ER doctors work in shifts, typically 8 to 12 hours long, and most full-time physicians work 12 to 15 shifts per month. That translates to roughly 36 to 44 clinical hours per week, which is fewer than most other specialties. The tradeoff is obvious: those hours are intense, unpredictable, and often overnight or on weekends. ER physicians also report some of the highest burnout rates in medicine, so “fewer hours” doesn’t necessarily mean an easier lifestyle.
The shift-based model does, however, give emergency physicians something unusual in medicine: truly off days. When a shift ends, there are no patient calls, no inbox messages to answer, no charts to finish at home. That clean separation between work and personal time is rare for doctors.
Specialties That Work the Most for Comparison
To put the low end in context, the specialties with the heaviest hours are almost all surgical. Vascular surgery, neurosurgery, and cardiothoracic surgery regularly push past 60 hours per week, with some surgeons logging 70 or more when call is factored in. General surgery, orthopedic surgery, and urology also trend high. These fields involve long operations, unpredictable emergencies, and frequent overnight call, all of which inflate total hours.
Primary care sits somewhere in the middle. Family medicine and internal medicine doctors typically work 45 to 55 hours per week, but a significant chunk of that time goes to documentation, inbox management, and administrative tasks rather than face-to-face patient care. OB-GYN physicians face a similar range, with the added unpredictability of deliveries pulling them into the hospital at all hours.
What Drives the Differences
Three factors explain most of the variation in physician work hours.
- On-call responsibility. Specialties tied to emergencies, like surgery, obstetrics, and hospital medicine, require doctors to be available nights and weekends. Outpatient specialties like dermatology and psychiatry rarely have this obligation, which keeps their total hours lower and their schedules more predictable.
- Practice setting. Doctors in private practice or outpatient clinics have more control over their schedules than those working in hospitals. Specialties that are almost entirely outpatient, like allergy and dermatology, naturally lend themselves to shorter, more regular workweeks.
- Part-time availability. Some fields make it easier to work part-time without career penalties. Psychiatry, dermatology, and radiology all have high rates of part-time physicians. Surgical specialties, by contrast, often require full-time-plus commitments to maintain hospital privileges and case volume.
Non-Clinical and Administrative Roles
Physicians who leave clinical practice for administrative, public health, or consulting roles often work the most traditional schedules. Preventive medicine physicians, for example, frequently work in government agencies or corporate wellness programs. About a third of preventive medicine doctors report working exactly 40 hours per week, with the rest working somewhat more. That’s a sharp contrast to the open-ended schedules most clinical physicians face.
Other non-clinical paths include medical directorships, pharmaceutical industry positions, and health informatics. These roles typically follow standard business hours with no call, no weekends, and no patient emergencies. The trade-off is lower compensation compared to most clinical specialties and less direct involvement in patient care.
Hours vs. Lifestyle
Raw hours don’t tell the whole story. A dermatologist working 42 hours a week in a calm outpatient clinic has a very different experience from an ER physician working 42 hours of overnight trauma shifts. Schedule predictability, emotional weight, physical demands, and the ability to disconnect after work all matter as much as the number on a timesheet.
Compensation also shifts the equation. Dermatology and radiology combine relatively manageable hours with high pay, which is why they’re among the most competitive residencies to match into. Psychiatry pays less but offers exceptional flexibility. Emergency medicine pays well and involves fewer total hours, but the physical toll of shift work catches up with many physicians over time. If your goal is the best ratio of income to hours worked, the answer changes depending on which specialty you’re comparing.
