Risk assessment of infection control in operating room based on hazard vulnerability and refined process management

To evaluate the effect of risk assessment in operating room infection control based on a hazard vulnerability analysis and refined process management, to clarify the weaknesses of infection control in operating rooms, and to provide evidence for the clinical prevention and control measures.

A refined risk assessment scale was designed based on a hazard vulnerability analysis and refined process management by screening the incidents related to operating room infections and determining the weighted coefficients. A total of 84 patients who underwent surgical treatment in our hospital from February 2018 to March 2020 were enrolled as the study subjects according to convenience sampling and randomly assigned into an observation group and a control group, with 42 patients in each group. The observation group patients were treated and cared for following a risk assessment based on a hazard vulnerability analysis and refined process management. The control group patients underwent conventional management. The effect of the risk assessment based on a hazard vulnerability analysis and refined process management for infection control was evaluated by comparing the hazard specific risk values, the infection incidents, and the two groups' nursing satisfaction.

After the intervention, the observation group had lower hazard specific risk values (all P<0.05), fewer infection incidents (P=0.044), and a higher patient satisfaction rate (P=0.047) than the control group.

The treatment and nursing intervention for the patients based on the risk assessment improved the efficiency of the risk management, reduced the number of infection incidents, increased the patient satisfaction rate, and improved the clinical efficacy for the surgery patients. Our findings provide a data reference for operating room infection control and prevention.
