The purpose of this study is to find out if there has been any change in the outpatient visit to tertiary care hospitals after the introduction of the new healthcare program that divides the roles of doctors and pharmacists and the reason for the change if there is any. Two tertiary care hospitals with the largest capacity of 1200 beds and two tertiary care hospitals with the lowest capacity of 600-700 beds were randomly selected. Data of the outpatient visits from March-May 2(xx), before the new healthcare system was adopted, were compared with the data from March-May 2001, after the new policy was adopted. Outpatient visits have decreased 5.8% after the new system. There has been a dramatic decrease, especially, in the department of OB-GYN and Pediatrics of tertiary hospitals. Decrease in re-visits is much higher than the first visits. Female patients decreased more than the male patients. Outpatient visits by economically active patients group aged 25-44 declined much. Tertiary hospitals in Seoul and Kyonggi Province, as well. Outpatient income of tertiary hospitals has dropped up to 14.7% due to the decline in outpatient visits and pharmaceutical income, and resell price system which in turn has caused the hospital financial deficits. While the new program has succeeded in lowering the use of antibiotics and injections, it has the pitfall of prescribing long days and expensive drugs. A full-fledged review of the system should be conducted for the establishment of the new system and I believe this study may be a useful references. Furthermore, more profound and overall studies on the chance in the patients use of hospitals are needed.

Purpose: The purpose of this study is to examine the relationship between the income level and the healthcare utilization by health insurance type in all cancer patients in year 2005. Methods: The target population was cancer patients with health insurance who used healthcare as a diagnosis code (C00-C97) from January 1 to December 31 of 2005. The Korea Central Cancer Registry Center's Cancer Patient Registry Data, the list of cancer patients of the National Health Insurance Corporation, and the claim data of the Health Insurance Review & Assessment Service were used. The I was the wealthiest, followed by II, III, IV. The V was the poorest in this study. For the analysis, the $x^2$-test, ANOVA (and Kruskal-Wallis test), and regression were used. Results: Outpatient and hospitalization medical expenses, and outpatient visit days of cancer patients with self-employed health insurance were highest in I (p<.001, respectively), and the hospitalization days were the highest in II (p<.001, respectively). Outpatient and hospitalization medical expenses, and outpatient visit and hospitalization days of cancer patients with occupational health insurance were the highest in I (p<.001, respectively). Outpatient and hospitalization medical expenses, and outpatient visit and hospitalization days in cancer patients were higher in I compared to V, and higher in II and III, IV compared to V (p<.001, respectively). Conclusion: Supporting plan for cancer patients' outpatient healthcare utilization are necessary. Moreover, we should make specialized strategy for low income cancer patients with self-employed health insurance when we develop quality improvement policy for inpatient service.

The code of the International Classification of Disease(ICD) is seriously questioned on its effectiveness in identifing an independent disease entity from similar conditions at general practitioner's offices. This study has attempted to show individual coding variations in ICD for similar ambulatory care conditions. It has been assumed that a following outpatient visit is regarded as the sane kind of visit owing to the same disease if a visit to the different source of care would be mad within an interval of less than two days. The 'D' health insurance association was selected for this analysis. The 'D' association had 153,298 members and made claims of 642,605 outpatient care in 1990. Out of the total outpatient claims, 8.6%(55,102 claims) were counted as the same disease which could meet the above assumption. Percent of conditions classified as the 10 leading causes of frequent visits which were matched accurately to the subsequent ICD diagnostic code found to be 15.8% on the average. The URI was noted for the highest concurrence rate of 20.4%. This proportion was even decreased to 11.6% on the case of chronic disease. Despite the fact that the assumption underlying the definition of the above same disease is rather rough and inappropriate, this study reveals that the code of ICD currently in use has weaknesses in seperating a certain independent disease from similar conditions at the outpatient setting. Thus, efforts need to be elaborated to meet the need of a new system of classification for conditions and diseases encountering at ambulatory care.

Background: This study was purposed to analyze the effect of spatial accessibility to the psychiatry department in general hospital on the outpatient visit of mental patients. Methods: Data was provided from the Statistics Korea and Statistical Geographic Information Service, National Health Insurance Service, Health Insurance Review and Assessment Service, and Korea Transport Institute in 2015. The study regions were 103 administrative regions such as Si and Gu. The 103 regions had at least one general hospitals with a psychiatry department. The number of outpatient visit of mental patients in regions was used as the dependent variable. Spatial accessibility to mental general hospital was used as the independent variable. Control variables included such as demographic, economic, and health medical factors. This study used network analysis and multi-variate regression analysis. Network analysis by ArcGIS ver. 10.0 (ESRI, Redlands, CA, USA) was used to evaluate the average travel time and travel distance in Korea. Multi-variate regression analysis was conducted by SAS ver. 9.4 (SAS Institute Inc., Cary, NC, USA). Results: Travel distance and time had significant effects on the number of outpatient visits in mental patients in general hospital. Average travel time and travel distance had negative effects on the number of visits. Variables such as (number of total population, percentage of aged population over 65, and number of mental general hospital) had significant effects on the number of visit in mental patients. Conclusion: Health policy makers will need to consider the spatial accessibility to the mental healthcare organization in conducting regional health planning.

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.

Purpose: this study investigates the effect of private health insurance on healthcare utilization. Methodology: For the analysis, we employed the three level nested two part model. Findings: the private health insurance adoption was associated with higher health care utilization. In particular, indemnity and fixed insurances adoption was associated with higher probability of outpatient visit, the number of outpatient visit and outpatient cost. While indemnity insurance adoption was associated with higher inpatient admission probability and inpatient days, fixed insurance adoption was associated only with higher inpatient admission probability. Practical Implications: indemnity and fixed insurance adoption were related with the adverse selection as well as moral hazard.

Background: Regular doctor visits are vital for hypertension patients, especially for who have never received hypertension medication or non-pharmacologic therapy. This study purposed to study factors affecting outpatient visits for patients diagnosed with hypertension. Methods: This study included 59,009 respondents with hypertension over 30 from 2019 Community Health Survey data. Outpatient visits were defined by having hypertension treatments such as medication or non-pharmacologic therapy. Logistic regression was used to examine the factors affecting outpatient visits using SAS ver. 9.3. Results: 57,081(96.73%) patients with hypertension were identified as those having a outpatient visit for hypertension treatments, whereas 1,928(3.27%) patients did not have visits. Patient's characteristics such as gender, age, periods of hypertension, education level, perception of the blood pressure, hypertension management education, place of living, body mass index, depression and diabetes were found to have statistically significant relationship with the outpatient visits. Practical Implications: There is a need to select patients with high blood pressure who are unlikely to visit for hypertension treatments based on the study results. For those, establishing a personalized management plan such as health education and counseling programs will be helpful for the successful implementation of national chronic disease management program.

Purpose: The aim of this study is to evaluate the efficiency of the outpatient clinics in a hospital, using DEA. Methods: Data were collected using an activity-based costing system, medical information system, and annual reports of customer satisfaction management team of a general hospital in a city. The input variables were the number of doctors, the number of nurses, and the number of staffs. The output variables were the number of treatment times, the number of outpatient clinic patients, the total profits from outpatient clinic, the patient's satisfaction score, and the number of re-visit appointments. EMS Window version 3.1 was used to measure the efficiency score and benchmarking analysis. Results: The average efficiency score of 24 outpatient clinics was about 82.01%. Thirteen outpatient clinics had 100% efficiency score among them. The lowest efficiency score was 57.56%. Conclusion: According to these results, we found that, generally, outpatient clinics were operated very efficiently. However, some outpatient clinics had low efficiency and they needed specialized outcome improvement strategies. To increase the efficiency of inefficient outpatient clinics, we will recommend using results of DEA, as a benchmark point of the most efficient outpatient clinics.

Limited studies examined Medical Aid recipients' perception for amount of medical use. This study aimed to identify self-perception(optimal, under and overutilization) for amount, and real amount of medical use, and to determine factors associated with the perception. Subjects were 2,489 Medical Aid recipients among top 2% overusers in 2005. 200 case managers(CM) managing them conducted survey. CM interviewed them using 2005 medical claiming data from the Health Insurance Review & Assessment Service and structured questionnaire. Despite of overusers, perception of overutilization was only 26.9% and 23.6% in Class I and Class II, and that of underutilization was 21.4% and 18.7% respectively. In Class I, monthly total outpatient cost per capita of overutilization perception in 2006 was 206 thousand won higher than 150 thousand won of optimal utilization. Amounts of outpatient visit-days and prescribed cases of overutilization perception were higher than those of optimal and underutilization(p <0.0001). In Class II, overutilization perception had more prescribed cases(p 0.004). After adjustment of confounding factors including age and sex, the associated factors(odds ratio) with overutilization perception were hypertension(1.25), arthritis(1.32), depression(1.66), visit of multi medical institutions(3.09), and those of the underutilization were female(1.34), disabled(1.27), no family support(1.49), living in medium and small city(1.48), experience of unabled-visit to medical institution(2.54), frequent visit-recommendation from physician (1.36). In conclusion, education and consult are needed for subjects to improve the reasonable decision of medical use, and the self-care ability to manage diseases and symptoms. We suggest reinforcing the alternative service in community instead of costly medical institution.

Background: Issues concerning with the classification accuracy of Korean Outpatient Groups (KOPGs) have been raised by providers and researchers. The KOPG is an outpatient classification system used to measure casemix of outpatient visits and to adjust provider risk in charges by the Health Insurance Review & Assessment Service in managing insurance payments. The objective of this study were to refine KOPGs to improve the classification accuracy and to evaluate the refinement. Methods: We refined the rules used to classify visits with multiple procedures, newly defined chemotherapy drug groups, and modified the medical visit indicators through reviews of other classification systems, data analyses, and consultations with experts. We assessed the improvement by measuring % of variation in case charges reduced by KOPGs and the refined system, Enhanced KOPGs (EKOPGs). We used claims data submitted by providers to the HIRA during the year 2012 in both refinement and evaluation. Results: EKOPGs explicitly allowed additional payments for multiple procedures with exceptions of packaging of routine ancillary services and consolidation of related significant procedures, and discounts ranging from 30% to 70% were defined in additional payments. Thirteen chemotherapy drug KOPGs were added and medical visit indicators were streamlined to include codes for consultation fees for outpatient visits. The % of variance reduction achieved by EKOPGs was 48% for all patients whereas the figure was 40% for KOPGs, and the improvement was larger in data from tertiary and general hospitals than in data from clinics. Conclusion: A significant improvement in the performance of the KOPG was achieved by refining payments for visits with multiple procedures, defining groups for visits with chemotherapy, and revising medical visit indicators.
