Thousands leave UCSF Parnassus ER amid overcrowding and staffing shortages

Thousands of patients are leaving UCSF Medical Center’s Parnassus emergency department before a doctor sees them, a sign that the hospital’s waits have become a patient-safety problem, not just an inconvenience. At the Parnassus Heights campus, the people most exposed are those who cannot afford to wait, including patients with time-sensitive conditions and older adults who may not be able to push for attention.

Nine UCSF Parnassus emergency-room providers said the department does not have enough nurses or beds to monitor and treat everyone in a timely manner. Their accounts included a man who fainted in the waiting room and was treated on the floor because no bed or room was available, and an elderly woman with a pulmonary embolism who spent three days in a hallway bed and initially had no assigned nurse. For a liver-transplant patient or anyone with an urgent condition, that kind of delay can quickly become a medical risk.

The strain does not stop at the Parnassus doors. San Francisco’s EMS rules require 90% of ambulance patient offloads to take 30 minutes or less, and the city can declare diversion when an emergency department is overloaded and cannot safely care for more 911 patients. Once diversion is declared, ambulances are sent elsewhere for the next two hours unless an exception applies. That means a crowded ER can slow the city’s entire ambulance flow, keep rigs tied up longer, and push patients toward other hospitals farther from home.

UCSF’s Department of Emergency Medicine says it provides comprehensive emergency care at five academic hospitals and UCSF-affiliated sites across northern California, underscoring how central Parnassus is to the region’s emergency network. Yet the accounts from inside the department point to a unit where patients are walking out before treatment, nurses are stretched thin, and hallway care has become part of the daily landscape. For San Franciscans who rely on UCSF for specialty and emergency care, the pressure at Parnassus is no longer contained to one waiting room.
