ObjectiveTo explore the establishment of evaluation index system of healthcareassociated infection (HAI) control in stomatological medicine.MethodsThe evaluation index framework based on theme framework approach was preliminarily formed, Delphi method and analytic hierarchy process (AHP) were used to construct grading evaluation index, judgement matrix was adopted to calculate the weight coefficient of index.ResultsThe qualitative and quantitative combined evaluation system, a threelevel evaluation index system with 47 indicators, was built，which was composed of six following dimensions: organization management, diagnosis and treatment environment, isolation measures, disinfection area, disinfectant medical devices and hygiene products, and medical waste. Among the tertiary indexes, complete documents of disinfectant medical devices and hygiene products (0.0362）, object surface cleaning and disinfection(0.0344), medical waste classification and collection (0.0326）, supervision and management（0.0323）, flushing and disinfection of dental unit water lines （0.0321） were of higher weight coefficients.ConclusionThe preliminarily established evaluation index system can provide a scientific basis and practical tool for carrying out evaluation and supervision, formulating standards, as well as developing curriculum content for HAI control in stomatological medicine.
