ObjectivesThe objectives were to develop a scientifically sound and feasible peer-to-peer assessment model that allows health-care organizations to evaluate patient safety in cardiovascular operating rooms and to establish safety priorities for improvement.MethodsThe locating errors through networked surveillance study was conducted to identify hazards in cardiac surgical care. A multidisciplinary team, composed of organizational sociology, organizational psychology, applied social psychology, clinical medicine, human factors engineering, and health services researchers, conducted the study. We used a transdisciplinary approach, which integrated the theories, concepts, and methods from each discipline, to develop comprehensive research methods. Multiple data collection was involved: focused literature review of cardiac surgery-related adverse events, retrospective analysis of cardiovascular events from a national database in the United Kingdom, and prospective peer assessment at 5 sites, involving survey assessments, structured interviews, direct observations, and contextual inquiries. A nominal group methodology, where one single group acts to problem solve and make decisions was used to review the data and develop a list of the top priority hazards.ResultsThe top 6 priority hazard themes were as follows: safety culture, teamwork and communication, infection prevention, transitions of care, failure to adhere to practices or policies, and operating room layout and equipment.ConclusionsWe integrated the theories and methods of a diverse group of researchers to identify a broad range of hazards and good clinical practices within the cardiovascular surgical operating room. Our findings were the basis for a plan to prioritize improvements in cardiac surgical care. These study methods allowed for the comprehensive assessment of a high-risk clinical setting that may translate to other clinical settings.
