Application effect of risk assessment in nosocomial infection control in Stomatology Department

Objective To explore the effect of risk assessment on nosocomial infection control in Stomatology Department. Methods In December 2017, members of the Hospital Infection Management Committee and the Hospital Infection Management Committee of the Department of Stomatology were organized to identify the risk of nosocomial infection in Stomatology Department by brainstorming method. Referring to the 'Risk Assessment and Plan for Epidemiological and Infection Control of the National Children's Medical Center in Washington, USA', the risk assessment mainly adopted matrix method. The top three risk priority factors were controlled. The incidence of nosocomial infection in Stomatology Department before and after risk assessment were compared. Results The three risk factors with the highest risk priority were multi-drug resistant bacterial infection, disinfection and isolation, and the use of disposable items. The first three risk factors were dealt with by PDCA (plan, do, check, act) cycle model, including risk factor analysis, improvement plan (time stage, target, measure) , tracking and next stage target. After risk assessment, the incidence of nosocomial infection in Stomatology Department was 0.73%, which was lower than 3.65% before risk assessment. The difference was statistically significant (χ2=7.754, P=0.005) . Conclusions The risk assessment of nosocomial infection in Stomatology Department can effectively find out the main potential risk factors, reduce the incidence of nosocomial infection, and standardize the management of nosocomial infection in Stomatology Department.
