On March 13, 2020, the City and County of San Francisco issued an order mandating the daily screening of healthcare workers for COVID-19 symptoms prior to entering the workplace. To expedite the process of screening thousands of employees each day, the Digital Patient Experience (DPE) team at UCSF partnered with Conversa Health to customize an online, chat-based screening that employees could use before heading to work. The screening tool presents employees with a series of questions based on CDC guidelines and UCSF Occupational Health Return-to-Work guidelines. Employees with no identified risk are cleared to enter UCSF using a designated line, and showing a date-stamped pass, similar to TSA Pre-Check. Employees with symptoms or other risk factors (e.g., recent travel to a hot spot area) receive instructions for further assessment and/or treatment. During the first month, over 100,000 screenings were completed with this tool, and usage continues to grow with expansion to the entire UCSF campus and other affiliations.
