ABSTRACT
This study aimed to assess the pattern of sentinel events reported to Ministry of Health of Saudi Arabia from January 2012 to June 2015. Sentinel event reports were examined for patient characteristics, type of event, outcome, cause and preventability. There were 433 sentinel events: 58.2% were deaths, 14.8% were unexpected loss of a limb or a function, 7.4% major medication errors and 7.4% retained instruments or sponges. Among the reported events, 44% were associated with surgical interventions and most were classified as preventable [91.6%]. Age 19-64 years was significantly associated with death as an outcome [P = 0.02]. Non-preventable sentinel events were significantly more likely among women than men [P = 0.01]. Unavailability of policy and procedures and/or failure to implement them [55%], and lack of proper communication [35%] and training [33%] were the main causes for the adverse events. Efforts should focus on enhancing the National Sentinel Events Reporting System, adopting criteria for effective reporting and ensuring availability and implementation of policies and procedures
