Objective: to assess the psychometric characteristics of the Hospital
Survey on Patient Safety Culture, to characterize the patient safety
culture, and to assess the influence of the sociodemographic and
professional variables on the safety culture dimensions. Method: a
methodological, observational, analytical and cross-sectional study
conducted with 360 nurses in which the Hospital Survey on Patient
Safety Culture questionnaire was used. The data were submitted
to descriptive and inferential analysis, as well as to feasibility
and validity studies. Results: the nurses’ mean age is 42 years
old, their mean time of professional experience is 19 years, and
they are mostly female. Good internal consistency was obtained
(Cronbach’s alpha: 0.83), as well as acceptable model fit quality
indices. Teamwork within units, Supervisor expectations and Feedback
and communication about errors were the dimensions that obtained
scores above 60%. Non-punitive response to error, Frequency of
events reported, Support for patient safety and Staffing presented
scores below 40%. These dimensions are influenced by age, schooling
level and professional experience. Conclusion: the psychometric
properties of the questionnaire certify its good quality. Teamwork can
be considered as an enhancing factor for the safety culture. Assessing
the safety culture allowed identifying problematic dimensions, thus
enabling planning of future interventions.
