지역별 의료서비스 이용의 변이를 파악하고 이를 기반으로 지역주민들이 양질의 의료서비스를 적절하게 이용할 수 있도록 하는 정책 방안에 대한 연구가 필요하다. 이에 본 연구는 2005년 환자조사 자료를 이용하여 우리나라의 병원급 이상 의료기관을 이용한 입원환자의 지역별 의료이용의 변이와 이에 영향을 미치는 요인에 대해 살펴보았다. 지역별 의료이용의 변이에 성, 연령과 같은 지역별 인구구조의 차이에 의한 효과는 직접표준화 방법을 이용하여 보정하였다. 분석결과 시도별, 시군구별 표준화 퇴원율, 표준화 재원일수는 차이가 있었으며, 표준화 퇴원율, 표준화 재원일수에 영향을 미치는 요인은 도시규모, 인구10만명당 병상수로 나타났다.

Purpose. This study is to find the degree of variations and trends of hospital services utilization for hypertensive disease, and have done the comparative analysis of the factors affecting occurring some variations. For this, this study uses the data for patients-survey and health-survey of a regional society by Korea Institute for Heath and Social Affairs in 2008; The regional units are classified into 160 of medium size medical service areas. Methods. I understand the level of variation by using index of Extremal Quotient(EQ) and Coefficient Variation(CV), and analyze critical factors influencing some differences in hospital services utilization by using multi-regression model. Results. The main results are followed:The first, in case of rate of hospital services utilization according to standarization of sex and age by small area, I find the variations of EQ 5.3 and CV 0.3; In Ho-nam, especially, the variation of high rank of 10 of age shows higher distribution. The second, the results analyzing the factors influencing on hospital services utilization by multi regression model are that a number of bed hospitals is significant positive relationship and EQ-5D of health behavior is significant negative one. Conclusions. To increase equity of hospital services utilization for hypertensive disease, this study requests the appropriate supply management of bed hospitals by region, efficient allocation of resources, and revitalization of the health promotion program.

본 연구는 심질환을 대상으로 지역간 입원의료이용의 변이정도와 양상을 파악하고, 변이 발생에 영향을 미치는 요인을 분석한 후 이를 개선하기 위한 정책방안을 도출하기 위해 수행하였다. 2008년도 환자조사와 국민건강보험공단 자료 및 지역사회건강조사 자료를 이용하여 전국을 160개 진료권으로 세분화 한 후 심질환 입원환자의 성 연령 표준화 입원율과 l인당 재원일수를 산출하는 한편, 이에 영향을 미치는 요인을 분석하였다. 연구 결과, 진료권으로 구분한 소규모 지역별로 성 연령 표준화 입원율과 1인당 재원일수에서 변이가 큰 것으로 나타났다. 그리고 지역간 표준화 입원율의 변이에 유의한 영향을 미치는 변수로는 인구만명당 특수의료장비수와 중등도이상 신체활동 실천율로 분석되었고, 표준화 1인당 재원일수의 변이에는 인구만명당 병상수, 특수의료장비수 및 현재흡연율이 통계적으로 유의한 영향을 미치는 변수로 나타났다. 정책적 시사점으로는 심질환자의 지역간 입원의료이용변이가 높은 만큼 지역별 의료자원공급의 효율적인 배분을 포함한 다각적인 정책적 개입과 더불어 환자 측면에서 의료이용을 합리적으로 유도할 수 있도록 제도적 보완책이 강구되어야 할 것이다.

Small area variations in health care utilization have long been studied as an important issue related to boto cost containment and quality assurance. This study was conducted to investigate if variations in hospital services across small geographic areas in Korea existed. The claims data of the fiscal year 1992 obtained from the regional health insurance societies were used for the study. Main findings of the research can be summarized as follows : 1. Extremal Quotients(EQ) of hospital expenditure per capita and hospital days per capita varied among diagnosis types. The EQ ranged from 2.05(cataract) to 41.67(pneumonia) in hospital expenditure per capita and from 1.86(cataract) to 45.89(pneumonia) in hospital days per capita. The diagnosis groups which showed high variation were pneumonia, cephalo-pelvic disproportion, gastritis and duodenitis, fracture of rib, and acute bronchitis. Those which showed low variation were acute appendicitis and cataract. 2. The EQ level of admission rate was different in terms of diagnosis types, ranging from 2.57(catarct) to 44.45(pneumonia). The variations were high in medical disorders such as pneumonia, oephalo-pelvic disproportion, gastritis and duodenitis and acute bronchitis, while relatively low in surgical conditions such as acute appendicitis and cataract. 3. As an indicator of service intensity, the EQ of expenditure per admission ranged from 1.67(acute appendicitis) to 31.27(essential hypertension). The diagnoses which had high variation were essential hypertension, gastric ulcer, whereas those which had low variation were cephalopelvic disproportion and acute appendicitis. With regard to hospital days per admission, the EQ ranged from 1.55(acute appendicitis) to 28.13(gastric ulcer) by diagnosis types. The diagnosis groups with showed high variation were gastric ulcer, essential hypertension, and acute bronchitis, whereas those with low variation were cephalo-pelvic disproportion, intervertebral disc disorders, and acute appendicitis. Both the expenditure and hospital days per admission showed lewwer variations than the expenditure per capita, hospital days per capita and admission rate. 4. Comparing patterns of variation in utilization indices, diagnoses such as essential hypertension, gastric ulcer, fracture of rib showed higher variations in expenditure per admission than in admission rates, whereas diagnoses such as pneumonia, cephalo-pelvic disproportion and gastric ulcer showed higher variations in admission rate than expenditure per admission. These findings suggest that wide variations existed in several diagnoses groups across small areas in Korea. Further research should be performed to investigate factors related to small area variations including provider behavior.
