ObjectivesThe goals were (1) to describe emergency department (ED) characteristics thought to be related to patient safety within the Pediatric Emergency Care Applied Research Network, (2) to measure staff perceptions of the climate of safety in EDs, and (3) to measure associations between ED characteristics and a climate of safety.MethodsTwenty-one EDs were surveyed to assess physical structure, staffing patterns, overcrowding, medication administration, teamwork, and methods for promoting patient safety. A validated survey on the climate of safety was administered to all emergency department staff members. Safety climate scores were compared to evaluate associations with ED characteristics.ResultsA total of 1747 staff members (49%) responded to the survey on the climate of safety. A minority of EDs had organized safety activities such as safety committees (48%) or walk-rounds (38%), used computerized physician order entry (38%), had ED pharmacists (19%), or had formal physician/registered nurse teams (38%). The majority (67%) treated patients in hallways. Most (67%) varied staffing on the basis of seasonal patient volume. Of the 1747 ED staff members (49%) responding to the survey, there was a wide range (28%-82%) in the proportion reporting a positive safety climate. Physicians' ratings of the climate of safety were higher than nurses' ratings, and perceptions varied according to work experience. Characteristics associated with an improved climate of safety were a lack of ED overcrowding, a sick call back-up plan for physicians, and the presence of an ED safety committee.ConclusionsLarge variability existed among EDs in structures and processes thought to be associated with patient safety and in staff perception of the safety climate. Several ED characteristics were associated with a positive climate of safety.
