Abstract

Hospitals are complex organizations, liable to emergency situations, which take care

of human life, using advanced technology.  The difficulty to operate under these conditions creates high frequency of medical treatment errors.

This study suggests a model for explaining medical treatment errors based upon safety

climate theory.

We identify four safety climate dimensions and examine the relationship among them: Manager’s Safety Practices, Priority of Safety ,Safety procedures suitability,

Safety information flow. The study also addresses the issue of safety climate strength.

Hypotheses: the first argued that the four distinct dimensions of safety climate will emerge.

The second, that priority of safety, will moderate the relationship between the other three

climate dimensions and safety performance. The third that the influence of the four climate dimensions on safety performance will be moderated by climate strength.

Population included 631 staff members, within 48 departments in three hospitals, who answered a questionnaire. Treatment errors were tallied using the hospitals’ archival

data and represented treatment errors of one year (2002).

Results, verified the four expected safety climate factors, demonstrated that all three interactions (safety priority with safety procedures suitability, safety priority with safety information flow, and safety priority with manager’s safety practices) were significant,

and demonstrated that climate strength moderated only the effects of safety information

flow and manager’s safety practices, on safety performance.

These results display the important role of safety climate in explaining patients’ safety. It expands prior research on safety climate and reveals the compound influence of climate strength on safety.
