Abstract

Purpose: As the National Health Insurance Service (NHIS) began to cover home oxygen therapy (HOT) services from 2006, it is expected that the new services have contributed to overall positive outcome of patients with chronic obstructive pulmonary disease (COPD). We examined whether the usage of HOT has helped slow down the progression of COPD. Methods: We examined hospital claim data (N=10,798) of COPD inpatients who were treated in 2007~2012. We performed ${\chi}^2$ tests to analyze the differences in the changes to respiratory impairment grades. Multiple logistic regression analysis was used to identify factors that are associated with the use of HOT. Finally, a generalized linear mixed model was used to examine association between the HOT treatment and changes to respiratory impairment grades. Results: A total of 2,490 patients had grade 1 respiratory impairment, and patients with grades 2 or 3 totaled 8,308. The OR for use of HOT was lower in grade 3 patients than others (OR: 0.33, 95% CI: 0.30~0.37). The maintenance/mitigation in all grades, those who used HOT had a higher OR than non-users (OR: 1.41, 95% CI: 1.23~1.61). Conclusion: HOT was effective in maintaining or mitigating the respiratory impairment in COPD patients.

목적: 2006년부터 가정산소치료 서비스에 대해 보장을 시작함에 따라, 기준에 부합하는 사람들은 가정산소 서비스이용에 대해 20%의 본인부담만을 지출하게 되었다. 이 같은 제도의 도입은 환자의 가정산소치료 서비스에 대한 부담을 경감시키게 됨에 따라 주요 이용자인 만성 폐쇄성 폐질환 환자들에게 긍정적인 효과를 미쳤을 것으로 예상된다. 하지만, 제도 도입 후 가정산소치료 서비스 제도의 효과에 대한 연구가 많지 않았고, 실증적 근거자료 또한 부족한 실정이다. 따라서, 본 연구는 제도 도입 후, 가정산소치료 서비스가 만성 폐쇄성 폐질환 환자들의 상태에 긍정적 영향을 미쳤는지를 알아보고자 한다. 방법: 만성폐쇄성 폐질환으로 2007년부터 2012년까지 병원을 방문한 사람(N=10,798)의 청구데이터를 분석에 이용하였으며, 가정산소치료 서비스 제도 적용의 기준인 호흡기장애등급에 따라 분포의 차이를 설명하기 위해 ${\chi}^2$ test을 하였다. 또한, 가정산소치료 서비스 이용에 대한 요인을 알아보고자 Multiple Logistic Regression Analysis을 하였으며, 가정산소치료 서비스 이용이 호흡기장애등급의 변화에 어떠한 영향을 주었는지 알아보고자 Generalized Linear Mixed Model 분석을 하였다. 결과: 분석대상 중 호흡기장애등급 1등급에 속하는 대상은 2,490명이었으며, 2/3등급에 속하는 대상은 8,308명이었다. 가정산소치료 서비스 이용에 대해서는 호흡기 장애등급 3등급이 1 또는 2등급에 비해 적게 이용하였다(OR: 0.33, 95% CI: 0.30~0.37). 또한, 가정산소치료를 이용함에 따라 환자의 상태의 변화에 대해 분석한 결과, 가정산소치료 이용자는 미이용자에 비해 상태의 완화 또는 유지에 대해 높은 값을 보였다(OR: 1.41, 95% CI: 1.23~1.61). 결론: 가정산소치료 서비스 이용은 만성 폐쇄성 폐질환 환자의 상태 악화방지에 대해서 긍정적인 영향을 준다.
