Patient Safety in medical facilities is an increasingly important issue with alarming costs, which has proven to be quite elusive. If improved, Patient Safety could save lives as well as minimize avoidable suffering and costs. A new strategy for improving Patient Safety Organizational Climate through leadership intervention is presented and tested in a randomized double-blind field-study. The study was conducted at a large hospital across all 27 inpatient departments with a total of 445 nurses and 27 department head nurses. Nurses filled out Safety Climate, Teamwork and Leadership questionnaires 6-8 weeks before and after the intervention phase. Safety behavior and medical errors were measured as complementary data. Throughout the 13-week long intervention stage nurses from all departments were administered a structured interview measuring perceived supervisory messages and task priorities. The collected data was presented to department head nurses from the experimental group in two sessions of leadership feedback held 7 weeks apart. Leadership intervention was tested for manipulation check and the dependent study variables were tested for changes over time in both groups. Results showed significant improvement of all measures in the experimental group but not in the control group. Theoretical and practical implications for a cost-effective intervention strategy for improving organizational climate are discussed.
