Kaiser model-based hazard vulnerability analysis in event risk assessment and emergency management of operating room in a hospital in China.

Objective: This study aimed to identify the high-risk events in the operating room so as to provide a decision-making basis for emergency management.

Method: The Kaiser model-based Hazard vulnerability analysis (HVA) was used to determine the risk matrix. The Delphi method was used to create the risk assessment form. The potential risk events were quantitatively evaluated. The relative risk percentages of the risk events were calculated to identify the top high-risk events.

Results: A risk matrix containing 4 components (natural disasters; technological hazards; human hazards; and hazardous materials) was determined, and a risk assessment form was created using the Delphi method. The top three high-risk events are as follows: internal radiation exposure (41%), infectious disease outbreaks (38%), and internal fires (33%). The emergency management measures for high-risk events were developed.

Conclusions: The Kaiser model-based HVA in event risk assessment of operating room can effectively identify potential high-risk events, determine emergency priorities, and optimize resource allocation, thereby ensuring the quality and safety of surgical treatment.
