Health Commission reviews response after ZSFG social worker was fatally stabbed; city orders security review

The San Francisco Health Commission on Dec. 15 heard a detailed directors report about a fatal stabbing at ZSFG that hospital and public health leaders called "heartbreaking" and "tragic." Director Dan Tsai told commissioners the incident occurred on Thursday, Dec. 4, when a patient stabbed a social worker, referred to in the meeting as Alberto, who later died.

"We had a very heartbreaking and devastating event on campus on Thursday," Tsai said, describing an outpouring of grief and a broad operational response across the Department of Public Health (DPH) and UCSF. He said the immediate focus was clinical care for the colleague, support for family and staff, and continuity of patient care at Ward 86 and nearby clinics.

Dr. Susan Ehrlich, who addressed the commission alongside Tsai, described the immediate security steps already implemented at Buildings 80 and 90 where Ward 86 operates. She said the hospital began using wands and has activated an Evolve weapons-detection system at the courtyard entrance, consolidated a single exit, provided lockers and bins for personal items, and placed ambassadors to greet and help patients through the new workflows.

"What we can do to honor Alberto is to learn everything we can from this incident and to make improvements so it never happens again," Ehrlich said. She emphasized the challenge of balancing a welcoming care environment with staff and patient safety and described operational adjustments being piloted now.

Tsai told the commission the department will conduct a full root cause analysis required by regulation and is also leading a broader DPH-wide review; the city has committed to retaining an independent firm to assess campus security more broadly. "We need to do a better job protecting the safety of our staff," he said, adding that many short-term measures will be maintained while the department works through longer-term policy and escalation procedures.

Commissioners offered condolences and pressed for staff involvement in changes. Several members said they supported fast interim steps but also recommended opportunities for staff to provide frank input before permanent changes are adopted. Commissioner Chao said the balance between security and access was "really important" and urged that staff perspectives—including anonymous input—be solicited.

The commission was told the mayor visited the campus and committed city resources to support safety and security. Tsai and hospital leaders said details of additional measures would be shared with staff in the coming days and that the commission should expect a fuller report at a subsequent meeting.

The commission adjourned into closed session later in the meeting and will continue oversight of changes in subsequent reports.
