Objective To explore the establishment of an evaluation index system for medical security of pregnant women and puerpera in communities under the background of infectious disease epidemic, in order to provide evidence for maternal health services.

Methods A total of 30 experts were consulted for two rounds by Delphi method to determine the three-level indicator system for evaluating the medical security of pregnant women and puerpera in the community under the background of infectious disease epidemic. Chromatography analysis method used to calculate the weight of each indicator.

Results The questionnaire response rates for the two rounds of expert consultation were 100%, with an expert authority coefficient of 0.9, and importance coefficients of 0.557 and 0.571, respectively. The coordination coefficients operability of expert opinions were 0.425, and 0.447, respectively. The statistical tests for the Kendall coefficients of importance and operability were statistically significant (all P < 0.001). Finally, a three-level indicator system for the evaluation of medical security of pregnant women and puerpera in infectious disease epidemic communities was set up and included 4 primary indicators, such as preventing and preparation, emergency response, evaluation and summary, and ability enhancement and reserve (with weights of 0.255 9, 0.253 6, 0.254 1, and 0.236 4, respectively), 10 secondary indicators, and 29 tertiary indicators.

Conclusion The weight of prevention and preparation indicators accounts for a relatively bigger proportion in the three-level indicator system for evaluating medical security of pregnant women and puerpera in the community. This suggests that grassroots health institutions should focus on preventing and preparing for medical security of them in daily work. Information registration, risk assessment, disease screening, and health education, etc. should be strengthened in order to ensure better respondence and medical security of pregnant women and puerpera in the endemic of major infectious diseases.
