Four Patients an Hour, Double-Booked: The Math That's Pushing Doctors Out of Primary Care

Dr. Ann Lebeck, a family medicine and sports medicine physician, published an essay this week describing what her workday actually looks like. Four to six patients an hour. Double bookings. A patient with hip pain who needs a thoughtful exam, but the schedule says move on.

She didn’t write it as an argument for any particular model. She wrote it as grief. “Many doctors,” she says, are “quietly grieving medicine.”

If you’re a primary care physician reading this, you probably don’t need her to tell you. You already know the math.

The Math That Doesn’t Work

Here’s what four to six patients per hour actually means. At best, you get 15 minutes per visit. At worst, with double bookings, you get 10. Subtract time for documentation, lab review, and the walk between rooms, and the share of that slot spent face to face with the patient is smaller still.

Dr. Lebeck describes primary care physicians becoming “referral managers” instead of doing the diagnostic thinking they trained for. A patient shows up with a complex complaint. The schedule doesn’t allow for a thorough workup, so you order imaging and send them to a specialist. The patient leaves confused. You feel like a traffic cop.

This isn’t a personal failing. It’s a structural one. Fee-for-service reimbursement rewards volume, not time. The only way to keep a traditional practice financially viable is to see more patients in less time. And when the schedule compresses, the first casualty is the relationship between doctor and patient.

The national numbers are less lopsided than the ones that usually get quoted, and it’s worth being precise about them. Measured panel sizes run between roughly 1,200 and 1,900 patients per physician — 1,751 at Kaiser Permanente, 1,266 in the VA — not the 2,500 that circulates as a standard. That 2,500 figure traces to a 2000 article speculating about an upper limit, and the researchers who went looking for its basis found it “was not based on data or a review of actual physician panel sizes.” Visit length is similar: when researchers timestamped 21 million primary care visits against EHR activity in 2017, the average exam ran 18 minutes.

So the squeeze Dr. Lebeck describes isn’t the national average. It’s what the average looks like once a specific practice’s economics push the schedule, and that’s the part fee-for-service reimbursement rewards.

The Doctors Who Are Walking Away

Dr. Lebeck isn’t alone in noticing. The number of clinicians practicing in membership-based models is growing, though the research doesn’t establish how many of them came from traditional practice rather than starting there. Between 2018 and 2023, the number of practices charging an annual or monthly membership fee nearly doubled, according to research from Harvard.

The trend is accelerating. More than 7,200 employers now offer DPC benefits to their employees, and over half of all DPC memberships are employer-sponsored. That’s not a niche. It’s a structural shift in how primary care gets paid for.

And it’s not hard to see why. DPC panels are a fraction of the size: the AAFP’s 2024 data brief puts the average DPC panel at 413 patients, and most practices report panels well under 1,000. Longer visits are the model’s central promise, though there’s no independent measurement of DPC visit length to put a number on it. There are no insurance claims to file, no prior authorizations to chase, no double bookings to squeeze in one more RVU. The monthly membership covers everything, so the incentive flips from volume to time.

As Dana Lujan wrote on KevinMD earlier this month, physician ownership has dropped from 76% in the early 1980s to just 35.4% today. Meanwhile, 77.6% of physicians are now employed by hospitals or corporate entities. The autonomy that drew most doctors to medicine is disappearing inside the same system that’s compressing their schedules.

DPC doesn’t fix everything. But it does fix the math. When your revenue comes from 600 memberships instead of a panel two to three times that size billed encounter by encounter, you can spend time with the patient in front of you. You can be the physician Dr. Lebeck describes wanting to be.

The Employer Connection

One reason this shift is picking up speed: employers are paying attention. Average employer-sponsored family health premiums hit $26,993 annually in 2025. That’s a number that makes CFOs look for alternatives.

When an employer contracts directly with a DPC practice, employees get a primary care physician who answers the phone, sees them the same day, and spends real time on their concerns. The employer gets a predictable per-member cost in place of a variable one. Vendors also market reduced downstream spending on ER visits and specialist referrals, but that claim rests on their own materials rather than an independent study, and it’s worth asking for the underlying numbers. The physician gets stable, recurring revenue without the billing overhead.

This isn’t theoretical. It’s already happening at scale. The question is no longer whether employer-sponsored DPC works. It’s how fast the adoption curve moves.

What This Means

Dr. Lebeck ends her essay with a question: whether physicians are “willing to reclaim the time.” For a growing number of them, the answer is yes, but not within the system that took the time away in the first place.

If you’re a physician seeing 25 patients a day in 10-minute slots, the frustration she describes isn’t news to you. What might be news is that the off-ramp is more accessible than it was five years ago. HSA eligibility for DPC memberships took effect in January. Employer adoption is at an all-time high. The infrastructure to run a membership-based practice continues to mature.

Nobody becomes a doctor to watch a clock. The primary care time crisis isn’t going to fix itself from inside the fee-for-service system. The doctors who are leaving aren’t giving up on medicine. They’re reclaiming it.
