Patient safety remains one of the biggest challenges for health care organizations. Patients and their families depend on a hospital to deliver outstanding care under the safest possible conditions. No nurse comes to work with the intent of harming a patient. The purpose of this study was to determine if a mandatory educational intervention demonstrated a change in nurses' perception of patient safety and in their willingness to report a medical error or near miss when utilizing a safety culture survey. The survey assesses a hospital's culture of safety by inquiring into the 12 patient safety dimensions. Data collection and analysis followed with nursing responses to the survey in a community hospital setting 2012 and again in 2014, after a mandatory educational intervention. Donebedian's theory was utilized to link the structure to organizational culture, the process to an educational intervention and the outcomes from the educational learning on the organizational safety culture.

The t test identified a significant differences in nurses' overall perception of patient safety before and after the mandatory educational intervention, t(280)=6.14,p+.001, d=1.11,a large effect. After the educational intervention, the nurses' perception of patient safety increased by approximately 15%. When comparing the 12 patient safety dimensions pre and post intervention every dimension except hospital handoffs, the post-intervention mean was always significantly higher that the pre-intervention perception of patient safety. Findings suggest that the educational intervention may have demonstrated an increase in nurses' perceptions of why humans make errors about safety behaviors nd error prevention tools that develop and maintain a culture of safety in an organization.
