OBJECTIVES: Although there has been considerable discussion about the social safety net, few studies related to effect of duration of continuous receipt of Medical Aid on healthcare utilisation have been conducted. Therefore, we investigate whether the duration of receiving Medical Aid affected medical care utilisation. SETTING: Data were collected from the Korean Welfare Panel Study conducted from 2008 to 2012. PARTICIPANTS: We included 11,783 samples. INTERVENTIONS: Estimating changes in their healthcare utilisation during specific time intervals (1, 2 and ≥3 years) after they switched from National Health Insurance to Medical Aid. PRIMARY AND SECONDARY OUTCOME MEASURES: Number of outpatient visits. RESULTS: The number of outpatient visits per year was 0.0.051-fold higher (p value: 0.434) among those who were Medical Aid beneficiaries for a continuous period of 1 year, 0.0.267-fold higher (p value: 0.000) among those who were beneficiaries for a continuous period of 2 years, and 0.0.562-fold higher (p value:<0.0001) among those who were beneficiaries for a continuous period of 3 years than it was among those who were beneficiaries of National Health Insurance. CONCLUSIONS: Our results reflect an association between the number of consecutive years of receiving Medical Aid and number of outpatient visits. Since duration of dependence is correlated with reduced exit rates, limits on length of benefits should be considered to strengthen the incentive to return to work.
