Outline
To establish a comprehensive evaluation index system for multidrug-resistant organism (MDRO) infection prevention and control in hospitals, and conduct empirical research to analyze current management status and propose improvement strategies.
The evaluation system was developed through literature review, Delphi expert consultation, and analytic hierarchy process (AHP). A questionnaire survey was conducted to assess current MDRO prevention and control practices.
Both Delphi rounds achieved 100% response rates, with expert authority coefficients (Cr) of 0.9736 and 0.9794 respectively. Kendall’s W values were 0.520 (χ2=645.23, P<0.01) and 0.537 (χ2=593.525, P<0.01) for successive rounds. The system demonstrated good reliability (Cronbach’s α=0.757) and validity (I-CVI=0.833-1.000, S-CVI/UA=0.938,S-CVI/Ave=0.990), comprising 3 first-level, 15 second-level, and 48 third-level indicators. Empirical data revealed suboptimal implementation: MDRO patient reporting rate (23.71%), isolation rate (59.79%), PPE utilization (14.95%), and hand hygiene compliance (53.09%). ICUs showed significantly higher MDRO infection rates (1.88‰, χ2=39.130, P<0.01), detection rates (25.58%, χ2=103.308, P<0.01), and identification rates (16.76%, χ2=1629.737, P<0.01) than other departments.
The developed evaluation system is scientifically sound and practical. Current MDRO prevention measures require substantial improvement, necessitating targeted interventions and precision management strategies.
