Objective To establish an evaluation system for nosocomial infection prevention and control ability based on the Delphi method, and to investigate its application in six hospitals at different levels in Yibin city.

Methods A total of 13 assessment indices were screened out by two rounds of the Delphi expert consultation method, and a linear regression model was established based on these 13 indices. The method of questionnaire survey and field investigation were used to obtain the values of indices in the six hospitals in Yibin, which were led-in the regression model to assess nosocomial infection prevention and control ability.

Results A total of 28 consulting experts completed two rounds of consultation, with a response rate of 93.3% and a self-rating authority coefficient of 0.87±0.08, and the Kendall coordination coefficients of the importance and feasibility of the second round were 0.833 and 0.799, respectively (P < 0.05). ② The linear regressin model was establishel including 13 indices of which were infection managencent system, number of personal in infection prevention and contiol, fundings of hardwart, et al. ③ The result of questionnaire survey and field investigation in the six hospitals were imported into the regression model, and the scores and ranking obtained were consistent.

Conclusion The evaluation system for nosocomial infection prevention and control ability based on the Delphi method is practicable and feasible and can be used to assess nosocomial infection prevention and control ability in hospitals at different levels, but more samples are needed for further validation.
