Factors associated with public and private healthcare utilization for outpatient care among older adults in India: A Wagstaff's decomposition of Anderson's behavioural model

Abstract

In India, an expanding ageing population will become a public health alarm, putting additional pressure on the healthcare system. Therefore, the current study aimed to examine the factors associated with outpatient healthcare choices among older Indian adults. We used data from the first wave of the Longitudinal Ageing Study in India (LASI, 2017–2018). A total of 34,588 individuals (age 45 years and over) who accessed outpatient healthcare services in the last 12 months during the survey were included in this research. A bivariate chi‐square test was used to present the percentage distribution of types of outpatient healthcare utilisation by background characteristics. Multinomial logistic regression and Wagstaff's decomposition analyses were employed to explore the interplay of outpatient healthcare utilisation and allied predisposing, enabling, and need factors and examine these factors' contributions to the wealth‐based inequalities in public, private, and other healthcare utilisation. Outpatient healthcare utilisation varied significantly according to socioeconomic and demographic factors. The findings suggest that consumption quintiles, place of residence, education, and health insurance were significant determinants of private and public healthcare utilisation and contributed to wealth‐based inequalities in healthcare choices. The current study emphasises the need to strengthen and promote public healthcare services.
