Nurses' Perception of Patient Safety Culture in a Referral Hospital: A Cross-Sectional Study

Healthcare systems are becoming increasingly complex which is helping to promote a 'culture of safety' within them based on the best scientific evidence available. Indeed, creating a positive institutional culture of patient safety is reflected in health outcomes. The aim of this present study was to describe the perception of culture of safety by nurses in adult inpatient units in a tertiary hospital and to analyze adverse events reporting. It was a cross-sectional study in which 202 nurses from adult hospitalization units of the Hospital Universitario y Politecnico La Fe in Valencia (Spain) participated. The perception of safety culture was measured using the Hospital Survey on Patient Safety questionnaire version 1.0, which consists of 42 items distributed in 12 dimensions that are considered strengths or weaknesses. In addition, adverse events related to nursing care during the study period and those reported in the official hospital registry were collected. Finally, the association between safety culture and sociodemographic and labor variables was explored. A total of 148 responses to the questionnaire were analyzed (Cronbach's alpha = 0.94), where seven dimensions and 25 items were identified as weaknesses. Two hundred and fourteen events were identified and none were reported in the official registry. Years of experience were significantly (p < 0.05) associated with safety culture. It is necessary to establish strategies to improve the perception of the safety culture of nurses, as well as to make nurses aware of the importance of notifying adverse events derived from health care.
