Purpose : Many studies showed that having a usual source of care improved the efficient access of healthcare service. However in Korea there have been few studies on the usual source of care. So this study aims to find whether having a usual source of care affect the medical utilization and expense. Methodology/Approach : We used the Korean Health Panel data in 2012, 2013 to examine the change of utilization and expenses in ambulatory care affected by having a usual source of care. We selected 1,215 hypertension patients without usual source of care in 2012 and performed linear regression analysis to identify the difference between treatment group(with usual source of care in 2013) and control group(without usual source of care in 2013). Then we performed analysis again separated by the age group. Findings : Among study population, 711(58.5%) reported that they have a usual source of care in 2013. Treatment group reported 1.85 less increase in outpatient visits and 69,234 won less increase in expense than control group with weak significance(visit ${\beta}$ -1.85 p-value 0.0807, expense ${\beta}$ -69,234 p-value 0.0541). People under the age of 65 showed significant change in outpatient visits for tertiary hospital (visit ${\beta}$ -0.78 p-value 0.0154, expense ${\beta}$ -91,462 p-value 0.0168). The analysis which focused outpatient for mild disease showed similar trend. Practical Implications : This study supports the positive effect of having usual source of care which decrease inefficient outpatient utilization. Promoting physician-patient relationships is important for efficiency of healthcare service.

Objective: This study aimed to estimate the impact of having and the type of usual source of care on the health literacy of rural residents. Methods: Using data from the 2021 Korea Health Panel Survey, the regression model was estimated, in which the presence and type of usual source of care, categorized as medical institutions and primary care physicians, were incorporated as explanatory variables. The level of health literacy was used as the dependent variable. Additionally, statistical analysis was conducted to compare how socio-demographic backgrounds and the presence and type of usual source of care are associated with health literacy between urban and rural residents. Results: The effect of usual source of care on the level of health literacy was significant only when the service provider was the public health institution. However, this effect was smaller for rural residents than for urban residents. When the usual source of care was an internal medicine or Korean traditional medicine doctor, the level of health literacy increased than the other types of doctor. Conclusion: To improve rural residents' health literacy, it is necessary to enhance access to public health care service and provide education programs.

Background: This study examined the effect of having a usual source of care on the degree of patient-centered communication among persons with disability. The role of the usual source of care has been emphasized to improve patient experience, especially for patients with complex health conditions. Methods: This study used the 2017-2018 Korean Health Panel data, and the final study observations were 22,475 (20,806 people without disability and 1,669 people with disability). We applied generalized estimating equation model to show the effect of having a usual source of care on patient-centered communication, and subgroup analysis considering the types and severity of disabilities. Results: Persons who have disabilities, compared with ones without it, significantly had more usual sources of care (32.4% vs. 24.6%). By type of disability, persons with mental (51.4%), internal organ (43.8%), visual (37%), and physical disabilities (31.6%) had more usual sources of care than hearing/speech (26.6%), and developmental disabilities (18.6%). The average score of patient-centered communication was higher among who had a usual sources of care (3.2 vs. 2.7), and the regression analysis showed that having a usual sources of care was positively associated with higher patient-centered communication score (𝛽=0.476, p<0.05). However, the positive effects of usual sources of care was not observed among persons with severe hearing/speech, developmental, and mental disabilities. Conclusion: This study showed that role of patient-centered communication was limited in persons with severe hearing/speech disabilities, developmental, and mental disabilities. The education programs and supports are needed to improve communication skills between medical staff and persons with specific types of disabilities.

Objective: This study was to explore the association between having a usual source of care and adherence to medicines in patient with chronic diseases. Methods: The 2012 Korea Health Panel was used as a data source. We analyzed 4,418 respondents that were diagnosed with chronic diseases and utilized health care services. Non-adherence to medication, a dependent variable, was defined as "not taking the medicines that were prescribed for treating chronic disease" or "not following the direction for medication". Whether having a usual source of care or not was used as a key independent variable, which was defined as having a regular site or a regular doctor for medical test, treatment, and consultation. Sex, age, education level, marital status, income, the type of health insurance, the number of chronic disease and CCI (Charlson Comorbidity Index) were included as covariates in the analysis. We conducted a multivariate logistic regression. Results: Totally, 30 percent of respondents reported to experience non-adherence to medication. Having a usual source of care was significantly associated with lower non-adherence to medication regardless its type, which is a regular doctor (OR=0.61, 95% CI=0.53-0.70) or a regular site (OR=0.67, 95% CI=0.58-0.78). Furthermore, having a usual source of care was associated with both of medication persistence (OR=0.66, 95% CI=0.54-0.81) and compliance (OR=0.65, 95% CI=0.56-0.76). Conclusion: Our results showed the possibility that usual source of care is able to conduct a positive role in improving adherence to medication with better management of chronic disease.

Purpose: The purpose of the study was to investigate and compare the usual source of healthcare and frequent visits to emergency departments. Methods: The study subjects were 7,252 individuals with chronic diseases who filled out the questionnaire of the 2013 Korea Health Panel Survey. Data were analyzed using chi-square test and logistic regression. Results: Compared to having a public health center or clinic as a usual source of healthcare, it is 1.341 times more likely for a chronic disease patient to visit an emergency department if the hospital is her/his usual source of healthcare, while it is 1.656 times more likely for the patient to visit a general/tertiary hospital. Conclusion: It is important to investigate visits at the emergency department requiring primary care for diseases.

Background: This study was conducted to analyze the impact of having a usual source of care on health behaviors of the middle aged and the elderly, in order to investigate the potential effect of enhancing primary health care in a Korean context. Methods: This study constructed a balanced panel of middle-aged and elderly samples using the Korea Health Panel 2016-2018, and fixed-effect models were used to analyze the data. Results: Among three sets of dependent variables (physical activity, smoking, drinking), statistically significant results were found only in physical activity. Subgroup analysis showed that this effect was not observed in the late elderly (aged 75 and older) and those without chronic diseases. Conclusion: Results of the study implied that enhancing primary health care among middle age and the elderly may have an effect on improving health behaviors. Moving forward to person-centered primary health care from disease-focused primary health care should be considered in high-risk groups such as the middle aged and the elderly with chronic diseases.

Background: Population aging is a serious problem in Korea. And we have experienced a rapid increase in the health expenditures of the elderly. The purpose of this paper is to analyze the effect of having a usual source of care (USC) for the elderly. Methods: This study used the Korea Health Panel Survey data of 2012, 2013, 2016, 2017, and 2018. The sample was the person who answered the USC questions among the elderly. The panel logit model was used to analyze the determinants of having USC and the panel simultaneous equation model was used to analyze the effect of having USC among the elderly on the medical expenses, medical utilization, and subjective health status. Results: The estimation result shows that age, income, marriage, and so forth turn out to be the factors of having USC. Having the clinic level USC is estimated to reduce the health care utilization and the health expenditure and to improve the subjective health status. Conclusion: It is expected that the result of our analysis will provide evidence for encouraging having USC.

Background: Concentration of patients to large hospitals is serious problem in Korea. The purpose of this paper is to propose appropriate policy direction to relieve concentration of patients to large hospitals. It is focused on evaluation of the possibility of family doctor system as a policy alternative to relieve concentration of patients to large hospital by empirically analyzing the effect of usual source of care (USC) on large hospitals medical care use. Methods: Korea Health Panel conducted 2009, 2012, 2013 by KIHASA (Korea Institute for Health and Social Affairs) and NHIS (National Health Insurance Service) was used for analysis. For dependent variables, first, the ratio of the amount of using large hospital to total amount of using medical care, and second, the amount of using large hospital are estimated. Independent variables are having an USC and type of USC. Panel analysis was done with above variables. Results: Main results are as follows. First, having an USC increases using large hospital. Second, having a domestic clinic type USC decreases using large hospital and ratio of using large hospital. Third, the effect of domestic clinic type USC is greater in older group, less income group, worse health status group, not having private insurance group, and having chronic disease group. Conclusion: These results show that family doctor program can be a policy alternative to relieve concentration of patients to large hospital. Nonetheless, primary care system in Korea is unsatisfied. It is recommended to reinforce primary care system and family doctor system to relieve concentration of patients to large hospitals.
