Construction of a path for optimizing the health management of HBV infections among pregnant and lying-in women based on a Delphi method / 预防医学

ABSTRACT

Objective@#To establish an optimized path for health management of HBV infections among pregnant and lying-in women based on a Delphi method, so as to provide the evidence for intensifying the interruption of the mother-to-child transmission of HBV.@*Methods@#Based on literature review and previous studies, the preliminary framework and contents of the optimized path for health management of HBV infections were constructed. Experts from epidemiology, clinical medicine and maternal and children healthcare were invited to participate in two-round Delphi consultations, and the preliminarily designed indicators were screened and revised. The score for feasibility of each indicator was calculated, and the weight of each indicator was estimated using a proportional distribution method.@*Results@#Sixteen experts participated in the consultation, including 13 women. The participants had a mean age of (45.69±5.71) years, and a mean employment duration of (23.06±7.05) years. All participants had a degree of bachelor and above, and there were 14 experts with vice senior professional titles. The mean positive coefficient was 96.88% and the mean authority coefficient was 0.790 during the two-round expert consultations. There were significant differences in the coordination coefficient of importance, necessity and feasibility of indicators at all levels (P<0.05), and the coefficient of variation of the feasibility was all less than 0.250. The final optimized path for health management of HBV infections among pregnant and lying-in women included 6 primary indicators, 17 secondary indictors and 73 tertiary indicators. Among the primary indicators, delivery management (0.173 4), screening and evaluation (0.172 8) and pregnancy management (0.172 7) had a high weight.@*Conclusion@#A scientific and reliable optimized path is created for health management of HBV infections among pregnant and lying-in women, which has a potential value for improving the interruption of mother-to-child transmission of HBV.
