Abstract

The purpose of this study was to examine the incidence rates of pressure ulcers depending on the types of healthcare organizations and to determine whether the characteristics of patients and facilities influence on the incidence of pressure ulcers in long term facilities. We analyzed data on 796,857 patients of the 2009 National Patient Sample which was extracted from to claims for medical fees to Health Insurance Review & Assesment Service(HIRA). A total of 3.2% of patients(n=25,339) had at least 1 pressure ulcer during their hospitalization. The pressure ulcer rates were highest in long term care facilities(8.2%, n=11,895) following general hospital(2.7%, n=8,052), hospital(1.7%, n= 5,059). According to logistic regression analysis, urinary incontinence (Odds ratio(OR)=2.462, 95% confidence interval(CI)=2.038-2.974), hypertension(OR=1.456, CI=1.400-1.515), peripheral vessel diseases (OR=1.357, CI=1.200-1.534) were significant predictors of pressure ulcers. As the number of diagnoses, age, and the number of doctors per 100 beds increased, the incidence of pressure ulcers increased. In addition, more number of beds was associated with fewer pressure ulcers.

본 연구는 2009년 한 해 동안 건강보험심사평가원의 요양급여 전체 청구자료를 통계적으로 표본 추출 한 환자표본자료를 이용하여 의료기관 종류 별 욕창 발생현황과 이중 요양병원 환자의 욕창 발생에 영향을 주는 요인을 규명하기 위해 시도되었다. 전체 의료기관 입원환자의 3.2%(n=25,339)에서 욕창이 발생하였다. 의료기관 종별로는 요양병원 입원환자의 8.2%(n=11,895)에서 욕창이 발생하여 종합병원(2.7%, n=8,052), 일반병원(1.7%, n=5,059) 보다 상대적으로 높은 비율을 보였다. 요양병원 입원환자(n=144,523)의 욕창발생에 영향을 주는 요인을 분석한 결과 의학적 진단 중 요실금을 가진 환자 군이 가지지 않은 군에 비해 욕창 발생이 2.46배 유의하게 높게 나타났다(Odds ratio(OR)=2.462, 95% confidence interval(CI)=2.038-2.974). 더하여, 고혈압질환(OR=1.456, CI=1.400-1.515), 말초혈관 질환(OR=1.357, CI=1.200-1.534)군 순으로 욕창 발생에 영향을 미쳤다. 진단 수(OR=1.193, CI=1.187-1.199)와 나이(OR=1.011, CI=1.009-1.012) 및 100침상 당 의사 수(OR=1.063, CI=1.035-1.091)가 증가할수록, 의료기관의 전체 침상수(OR=.889, CI =.869-.909)가 적을수록 욕창발생은 유의하게 높은 것으로 나타났다.
