This study describes the development of the Patient Safety Climate in Healthcare Organizations survey, a novel instrument for evaluating organizational culture of safety. The authors grouped the survey questions into nine dimensions of safety, including organizational factors, work unit factors, and individual factors. The instrument was tested on more than 20,000 health care workers and proved to have good reliability. A prior systematic review discussed the strengths and weaknesses of other existing safety culture surveys. Thus far, only the Safety Attitudes Questionnaire has demonstrated a link between perceptions of safety culture and safety outcomes.
