Background: There has been rising interest in chronic disease management worldwide. Hypertension is one of the major chronic diseases that requires a usual source of care (USC) in primary care. This study was conducted to analyze the current status of having a USC for Korean adults with hypertension.
Methods: We used the 2013 Korea Health Panel data. The study population comprised adults aged 18 years or older with hypertension (n=2,633).Sociodemographic variables by types of USC, usual places by types of medical institution, and primary care attributes by types of usual places were analyzed using bivariate analyses. Multiple logistic regression analyses were performed to define sociodemographic factors associated with having a regular doctor (RD) controlling for health status. Cross-sectional weights were applied to all analyses.
Results: Those having a USC comprised 66.2% (40.0% for RDs). Private local clinics were the most frequent type of usual place (63.3%). Those who responded positively to comprehensiveness and coordination comprised 75.2% and 29.7%, respectively. The longitudinal relationship between RDs and patients was 7.7 (±5.3) years. Compared to those with 6 years or less of education, those with 7–12 years (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.05–1.67) and those with 13 years or more (OR, 1.51; 95% CI, 1.08–2.12) of education were associated with an increased probability of having a RD.
Conclusion: The percentage of Korean adults with hypertension having a RD is very low. Even those having a RD experience poor coordination, healthcare policies to improve coordination, as well as promote having a RD, are necessary for effective hypertension management in Korea.
