[Construction of epidemiological evaluation system for HIV testing and screening strategies based on Delphi method].

Objective

To establish an epidemiological evaluation system for HIV testing and screening strategies, and to provide a basis for the continuous optimization of testing and screening strategies.

Methods

The preliminary indicator system was developed based on the Donabedian structure-process-outcome model. A two-round Delphi survey was conducted to assess the importance and feasibility of each indicator. The final indicator system was determined by comprehensively considering the evaluation results and expert opinions.

Results

Twenty experts were invited to conduct two rounds of consultations. The active coefficients of the experts were 100% in both rounds of consultation, and the mean authority coefficients were 0.77 and 0.76, respectively. The Kendall's W coefficients for indicator importance were 0.075 and 0.154 in the two rounds, and those for feasibility were 0.109 and 0.149 (both P<0.05), indicating increasing consistency among expert opinions. The final indicator system consisted of 3 primary indicators (structure, process, and outcome), 9 secondary indicators, and 39 tertiary indicators.

Conclusion

The indicator system constructed in this study provides a reference for the epidemiological evaluation of the HIV testing and screening strategies.
