A review of the literature examining linkages between organizational factors, medical errors, and patient safety

The potential role of organizational factors in enhanced patient safety and medical error prevention is highlighted in the systems approach advocated for by the Institute of Medicine and others. However, little is known about the extent to which these factors have been shown empirically to be associated with these favorable outcomes. The present study conducted an intensive review of the clinical and health services literatures in order to explore this issue. The results of this review support the general conclusion that there is little evidence for asserting the importance of any individual, group, or structural variable in error prevention or enhanced patient safety at the present time. Two major issues bearing on the development of future research in this area involve strengthening the theoretical foundations of organizational research on patient safety and overcoming definitional and observability problems associated with error-focused dependent variables.
