San Francisco's busiest and most stretched emergency department — Zuckerberg SF General, a trauma center serving uninsured patients at volumes 50% higher than UCSF — cut its ER walkout rate by more than half in a single year. Miles uphill at Parnassus, UCSF's flagship emergency department, sitting inside a health system with an $809 million operating surplus, logged the worst walkout rate of any hospital in the city.

State data analyzed by the SF Standard shows UCSF Parnassus had a 5.6% walkout rate in 2025 — 2,243 patients left before seeing a licensed provider, a 20% jump from 2024 — while patient complaints at the facility ran five times higher than the California average. The divergence with SF General isn't just a healthcare statistic. It's an accountability story. SF General answers to the city. UCSF answers to UC Regents in Oakland. And the gap between those two chains of command is now measured in thousands of patients walking out the door.

State records reviewed by the SF Standard, published June 25, show that the Parnassus emergency department led San Francisco in patients leaving without being seen — 5.6% in preliminary 2025 data, compared with a national average of roughly 2%. The raw count rose from 1,872 in 2024 to 2,243 in 2025, even as the department's roughly 40,000 annual visits stayed flat.

That figure matters most when placed next to what happened a few miles southeast. Zuckerberg SF General, the city's only Level I trauma center and safety-net hospital for patients without insurance or primary care, had spent years topping San Francisco's walkout rankings — driven largely by a surge in drug-related admissions. Then, between 2024 and 2025, it slashed that rate from 7.6% to 3%, even as emergency visits climbed from roughly 61,000 to 64,000. More patients, worse cases, less money. Fewer people walking out.

UCSF Health officials have argued their problems aren't unique to Parnassus — and statewide, that's partly true. A 2023 JAMA study documented a decade of deterioration in California ERs: more visits, fewer facilities, sicker patients. The boarding crisis — admitted patients occupying emergency beds because no inpatient rooms are available — is a genuine nationwide challenge. But Parnassus is a quaternary referral center, the system's flagship, designed for the rarest and most complex cases. Its patients are there because nowhere else can handle them.

Among them, last December: Kelsey M., a liver transplant patient since infancy, severely immunocompromised and unable to receive live vaccines her entire life. She arrived at Parnassus in significant distress, fluids flowing through a port in her chest, only to find herself separated from a patient on a breathing machine by a curtain. When that patient began coughing, she stepped into the hallway. A nurse told her she couldn't stay there. There were no other beds. "I was too scared to stay," she told the Standard. Against medical advice, she walked out.

ER workers described to the Standard a department where space is so constrained that end-of-life conversations happen in open hallways. "Family, patient, multiple doctors at the bedside, discussing the end of life, next few hours or days in a busy place with people screaming, floor-cleaners going by, and dinner trays being put out," one worker said. Another described asking patients about bowel habits and incontinence in shared spaces: "There's no sense of privacy or dignity in that situation."

The Dissent has been tracking UCSF's staffing crisis since April, when the health system implemented a hiring freeze and cut new-graduate nurse programs for another year. In May, reporters documented ER providers sounding alarms that patients were directly suffering from understaffing. The Standard's state-data investigation now provides the first hard numbers confirming what those workers described.

UCSF Health responded to the Standard with a statement citing "limited capacity to serve patients who seek our care" and noting that the boarding crisis is a national problem. That's true — and also beside the point when SF General, with a fraction of UCSF's financial resources, managed to turn things around in twelve months.

What SF General did, UCSF could do. But SF General had to: it's a city hospital, under the Department of Public Health, ultimately accountable to the Board of Supervisors and the mayor. When DPH failed, the city's political machinery could be deployed. UCSF is a UC system institution, accountable to Regents who meet in Oakland and whose mandate runs statewide. Mayor Lurie has no lever to pull. The Board of Supervisors has no vote. San Franciscans who depend on UCSF's ER — many of them precisely because UCSF's specialists are their specialists, because their records live on that hill — have no political recourse.

The $809 million surplus makes this a choice, not a constraint. The boarding crisis makes it a policy, not a surprise. And 2,243 patients walking out the door in a single year makes it a public health problem the city can name but cannot compel anyone to fix.
