The value of using health insurance claim database is continuously rising in healthcare research. In studies where comorbidities act as a confounder, comorbidity adjustment holds importance. Yet researchers are faced with a myriad of options without sufficient information on how to appropriately adj...

임상적 견해 혹은 통계적 검정결과에 따라 유의한 질환만을 선택적으로 보정하는 방법의 제한점은? | 일반적으로 동반질환 보정방법은 기존에 발표된 연구결과를 근거로 임상적 견해 혹은 통계적 검정결과에 따라 유의한 질환만을 선택적으로 보정하는 방법(ad hoc selection)과 동반질환 측정도구를 사용하는 방법이 있다[2]. 전자는 동반질환에 대한 서로 다른 견해 또는 통계적 접근방법으로 연구들 간의 비교가능성이 낮다는 제한점이 있다[3]. 동반질환 보정에 대한 관심이 높아짐에 따라 Charlson 동반질환지수(Charlson comorbidity index, CCI)와 Elixhauser의 동반질환(Elixhauser’s comorbidity measure, ECM) 과 같이 동반질환을 종합적으로 평가하고, 다양한 질환에 적용할수 있는 측정도구를 사용한 연구들이 보고되었다. | |
중증도 보정이란? | 건강보험청구자료를 자료원으로 하는 연구들은 대부분 관찰 연구로, 이들 연구에서는 선택 편향과 교란요인을 최소화하기 위한 중증도 보정은 필수과정이다[1]. 중증도 보정은 관심결과에 영향을 주는 요인들을 통제하는 과정으로, 건강보험청구자료에는 연령, 성별, 수술 여부, 동반질환 등과 같은 후보 보정요인들이 포함되어 있다. 특히 동반질환은 주진단과는 관련이 없으나 합병증과 사망, 재원일수, 진료비 등을 증가시킨다는 점에서 중요한 중증도 보정변수이다. | |
건강보험청구자료와 같은 행정자료가 다양한 보건의료 연구에서 활용되고 있는 이유는? | 보건의료 연구에서 건강보험청구자료의 가치가 높아지고 있다. 건강보험청구자료와 같은 행정자료는 실제 보건의료 환경을 반영하고, 장기간 추적이 가능하다는 점에서 성과(outcome) 연구, 역학 연구, 약물감시 등 다양한 연구에서 활용되고 있다. 특히 국내에서 공공 데이터 개방정책이 확대됨에 따라 건강보험청구자료를 사용한 연구들이활성화되고 있다. |
