The majority of early patient safety interventions focused on the hospital setting, but there is a growing determination to improve safety practices across the ambulatory sphere as well. This AHRQ-funded project, Proactive Reduction of Outpatient Malpractice: Improving Safety, Efficiency, and Satisfaction (PROMISES), created a collaborative learning network of Massachusetts primary care practices and patient safety leaders. Program coaches visited 16 pilot primary care offices and worked directly with improvement teams to implement safe practices. The project also includes a report from physicians, malpractice insurers, and policy experts translating the hospital-based consensus statement, "When Things Go Wrong," into clear recommendations for ambulatory adverse events. The Web site provides various materials, including recorded lectures, case study videos, and tools to assist individuals and teams with enhancing outpatient safety. A past AHRQ WebM&M perspective explored patient safety in the office setting.
