Abstract

In this study, we propose a new order selection method for clinical pathway development in acute appendectomy. This method is based on the lift concept which is popular in association rule discovery and, starting from the orders with more frequencies, sequentially removes the negatively associated orders which have lift values somewhat less than one. The orders in acute appendectomy we consider in this study are test and medical treatment items respectively, and since there are different order patterns before, during, and after operation, three different order selections are made for each. The selection results are somewhat different from those selected only by the order of more frequencies. Specifically, the selection results of two methods are different in 1 or 2 orders for medical treatment items and in maximum 5 orders for test items, respectively.

이 논문에서는 맹장염 수술에서 임상경로 개발을 위한 새로운 처방 선택 방법을 제안하였다. 처방 선택 방법은 연관성 규칙발견에서 흔히 사용되는 향상도에 근거하고 있으며 구체적으로 빈도가 높은 처방부터 출발하여 이것과의 향상도가 1에 못 미치는 음의 연관성 처방들을 순차적으로 제거하는 방법이다. 이 연구에서 관심을 두는 맹장염 수술 처방은 치료와 검사 항목이며, 치료와 검사 항목이 수술 전, 수술 중, 수술 후에 다른 행태를 보이기 때문에 세 가지로 구분하여 처방 선택 방법을 적용하였다. 이 처방 선택의 결과는 단순 빈도순에 의한 처방 선택의 결과와 약간의 차이를 보였다. 구체적으로 치료 항목에서는 1-2개 정도의 처방 선택이 달라졌으며, 검사 항목에서는 5개까지 처방 선택이 달라졌다.
