我们提出了一种方法，用于定义和经验验证发作的酗酒治疗从卫生保健utilization records.Study Design AND SETTTINGThe study包括利用记录从86,207例患者参加了一个大型的管理行为护理公司谁有至少一个酗酒的遭遇在1991年和1998年之间。治疗事件被定义为在没有遭遇的“明确区域”之前与行为护理公司进行酒精中毒治疗的最低数量。统计程序，选择一个子集的发作定义从一些候选人的定义和方法，用于评估收敛和标准的有效性的定义presented. PROTESTThe患者的百分比至少有一个发作的酗酒治疗从43%到77%不等，结果是更敏感的最低数量的遭遇所需的长度比明确的区域。标准有效性并未揭示任何明确的“获胜”定义;当需要2到3次接触时，阳性预测能力增加得最快。结论酗酒治疗事件的最可靠定义需要3到4次接触，明确的区域为3到4个月。
OBJECTIVEWe propose a method for defining and empirically validating episodes of alcoholism treatment from health care utilization records.STUDY DESIGN AND SETTINGThe study includes utilization records from 86,207 patients enrolled in a large managed behavioral care company who had at least one alcoholism encounter between 1991 and 1998. Treatment episodes are defined as a minimum number of alcoholism treatment encounters with the behavioral care company prior to a “clear zone” of no encounters. Statistical procedures to select a subset of episode definitions from a number of candidate definitions and methods for assessing the convergent and criterion validity of the definitions are presented.RESULTSThe percentage of patients having at least one episode of alcoholism treatment varies from 43% to 77%, with the results being more sensitive to the minimum number of encounters required than the length of the clear zone. Criterion validity does not reveal any clear “winning” definitions; positive predictive ability increases most rapidly when going from 2 to 3 encounters required.CONCLUSIONThe most robust definitions of an alcoholism treatment episode entail 3 to 4 encounters with a clear zone of 3 to 4 months.
