Patient safety culture: effects on errors, incident reporting, and patient safety grade.
Safety culture is associated with increased error reporting, improved teamwork, and decreases in patient harm. This study used the Safety Attitudes Questionnaire to explore the relationship between the dimensions of safety culture and four outcomes: making an error, witnessing an error, incident reporting, and patient safety grade. The strongest dimension of safety culture was teamwork climate and the lowest was perceptions of management. Patient safety grade and overall safety culture were strongly positively associated.
