RESUMO
@#The increasing of Independent National Health Insurance (NHI) membership is one of the indicators to achieve Universal Health Coverage. One of the challenges in extending such coverage is reaching it out to the informal sector. This study was aimed to analyze the determinants of Independent NHI ownership in Indonesia. This study used cross-sectional design, and the data were derived from Indonesian Family Live Survey (IFLS) 2014. 6,888 individuals aged ≥40 years were the sample of this study. To analyze the data, chi-square analysis and logistic regression were used. Based on the analysis, the proportion of respondent with Independent NHI is 16.6%. The ownership of independent NHI is influenced by the following factors: age 40-55 (PR=1.72 95%CI 1.41-2.09, p-value <0.001), Sumatra Island (PR=7.67 95%CI 5.55-10.59 p-value<0.001), very rich (PR = 2.26 95%CI 1.85-2.75 p-value <0.001), history of chronic disease (PR=1.33 95%CI 1.15-1.53 p-value<0.001), junior high school (PR = 2.21 95%CI 1.92-2.55 p-value<0.001), and urban (PR=1.79 95%CI 1.57-2.04 p-value <0.001). Region is the most dominant variable related to NHI ownership (p-value <0.001; Exp B= 7.03; 95% CI: 5.06-9.77). Independent NHI membership has not been maximal, yet. To increase this participation, the Social Security Administrator should approach each region with low NHI membership through promotion, socialization, and education about registration and the benefits of independent NHI.
