目前台灣有4 所提供藥物濫用者戒治處遇服務的獨立機構，為了強化國內戒治成效，在95 年1 月1 日同時成立台中、新店及高雄戒治所，此種新成立機構強調整合醫療、社工及心理諮商服務以便強化戒治成效，為瞭解新成立戒治所成效，本篇研究報告於民國97 年5 月針對新成立台中戒治所及未成立前的台中監獄戒治分監的再犯率進行分析比較，依照法務部統計，在毒品戒治成立開始至93 年6 月底，其失敗率為42.8％，本研究嘗試利用存活分析驗證是否在成立新戒治所前後再犯率有所不同，研究結果發現新成立戒治所有相對較低的再犯機率，此研究結果可作為當前戒治分監受戒治人是否要移送至新成立戒治所的參考。

Currently, there are four new drug treatment institutions for convicted drug offenders in Taiwan. To enhance the efficiency of the Taiwanese drug treatment system, three (Taicheng, Shin-tien, and Kaoshuang Drug Treatment Center) of four institutions were transformed into independent treatment institutions on January 1,2006. These new institutions focus on greater integration among medical care, social work, and psychological counseling in order to increase the effectiveness of drug treatment. To better understand the effectiveness of these new institutions, comparison
of recidivism rates was made between one group of Taichung Drug Treatment Center and a previous cohort in May 2008. According to the official report, recidivism rates from the beginning of the drug treatment program to the end in June, 2004 reveals a failure rate of 42.8%. This study is an attempt to test whether there is a significant difference in recidivism rates between new institutions and the traditional drug
treatment style through survival analysis. Findings from this study reveal that the new form of treatment program has a relatively lower recidivism probability. It is considered a stepping-stone to determining whether remaining drug treatment branches need to be transformed into independent drug treatment institutions or whether inmates at those branches need to be transferred into these independent institutions.
