For hospital administrator Roland Pickens, Healthy San Francisco offers more than universal health care and coverage for the city’s uninsured. The three-year-old city program also is inspiring new approaches to streamlining medical care. Pickens, chief operating officer of San Francisco General Hospital, said the city health care program has led to innovations that include evening and weekend clinics, better care of patients with chronic conditions, electronic referrals that speed up the appointment process and a teleconferencing system that has doubled the availability of interpreters.
