Participation rate determines completion rate for specific health guidance as implemented by public health insurers

摘要

Completion rate for specific health guidance (SHG) based on specific health checkup (SHC) status in Japan is very low. This study aimed to clarify factors affecting the rate using questionnaire survey, which was conducted by mail between December 2016 and January 2017 for insurers in the Tokai Region of Japan. The subjects were 69 insurers and the collection rate was 25.1%. The SHG participation rate was 26.3%, and the SHG completion rate was even lower (23.6%) than the participation rate. The rate was significantly lower in dependents than in insured persons. Multiple regression analysis with SHG completion rate as the dependent variable indicated that only “participation rate in SHG” was positively related to completion rate. With SHG participation rate as the dependent variable, however, having an insurer who “implemented SHG,” “provided a thorough explanation to the subscribers of the objectives and significance of SHC and SHG when the programs were begun,” and “provided health guidance to non-obese individuals” and SHC implementation rate were positively correlated with participation rate. Multiple regression analysis using completion rates for the two types of SHG, i.e., motivational and active support, as the dependent variables indicated that SHG participation rate was a positive factor for each type. Participation rate in each type was positively correlated to “ex-post assessment of the SHG,” and/or insured persons. The primary factor affecting SHG completion rates was the SHG participation rate. It is also important, however, that insurers encourage participation of subscribers, especially dependents, in SHG.
