UCSF Medical Center offers an online scheduling service called InQuicker designed for patients who have nonlife-threatening medical needs. The service is available in the Emergency Department and in the Screening and Acute Care Clinic. Patients or caregivers select either the emergency room or urgent care, find an available treatment time, check-in online and wait from home until the chosen treatment time. People experiencing life threatening emergencies should not use InQuicker; please call 911 or go directly to an emergency room. The Emergency Department is located at 505 Parnassus Avenue, San Francisco, CA 94143.
