Abstract:Objective To establish a risk assessment system for infection control in oral outpatient department, grasp the high risk factors, and provide direction for the continuous improvement of infection control measures in oral diagnosis and treatment. Methods Based on the Delphi expert consultation method, clauses in national industry standards and specifications related to infection control in oral outpatient department were captured, and a risk assessment system was established, healthcare-associated infection risks of outpatient department of a tertiary stomatological specialty hospital were evaluated, high-risk points were quantitatively obtained with the failure mode and effect analysis method. Results The risk assessment system for infection control in oral outpatient department was established, including 3 first-level indexes, 15 second-level indexes and 74 third-level indexes.A total of 18 risk points were identified, including incorrect hand hygiene opportunities of health care workers, incorrect cleaning and disinfection methods for cleaning appliances, lower hand hygiene compliance rate than the hospital-wide baseline, non-timely disinfection for containers and areas of fabrics after use, unclear use location of cleaning appliances, incomplete or incorrect infection control system, irregular monitoring of ultraviolet lamp irradiation intensity, overloading of medical waste, without quality assessment on cleaning and disinfection, as well as incorrect wearing or removal of protective equipment. Conclusion The method for risk index system for infection control in the oral outpatient department is initially established, and the possible high-risk points in the implementation of infection control measures in the oral outpatient department are identified, which provide reference for the continuous improvement of infection control in the oral outpatient department.
