Factors Influencing the Intention to Use Primary Care Physicians Among People with Disabilities: Focusing on People with Severe Disabilities

Abstract

This study aimed to identify the factors influencing the intention to use primary care physicians (PCPs) among people with severe disabilities (hereafter "severe disabilities") and to provide evidence for strengthening the PCP program for people with disabilities. Data were drawn from the 2020 National Survey on Persons with Disabilities, and a total of 3,157 individuals with severe disabilities were analyzed. Andersen’s Behavioral Model was used as the theoretical framework. Chi-square tests were performed to assess associations between predisposing, enabling, and need factors and the intention to use a PCP. Multiple logistic regression analysis was conducted to identify significant predictors. The proportion of those intending to use a PCP was 49.6%. Significant predictors included age (predisposing factor); region, healthcare service use, sources of welfare information, experiences of difficulties due to COVID-19, health check-ups, and awareness of the PCP system (enabling factors); and self-rated health status, chronic disease, type of disability, need for assistance in daily living, and depressive symptoms (need factors). Notably, sources of welfare information and awareness of the PCP system emerged as key factors. Direct information from welfare, administrative, or religious organizations was more effective than mass media in promoting intention to use the service. These findings highlight the need for targeted outreach and awareness strategies to reduce regional disparities and enhance the nationwide implementation of the PCP system for people with disabilities.
