The main source of method discontinuation data comes from the calendar data of the Demographic and Health Surveys (DHS). DHS considers each episode of use contributed by a woman in the calendar to calculate method discontinuation. This means that episodes from women who contribute only one episode of contraceptive use are combined with episodes from women who contribute multiple episodes of use. This paper explores the DHS calculation of episode-based discontinuation and proposes new indicators that focus specifically on the client and puts her as the unit of analysis. First, we attempt to replicate the DHS calculation by applying weighted averages to episodes from women who contributed only one episode and from women who contributed multiple episodes of use. We then calculate three client-centered discontinuation indicators, using the five-year calendar data of the DHS. The methodology is illustrated by using data collected in Bangladesh, Kenya, and Indonesia. Starting with the very first method used and reported in the calendar and following use over 12 months, we develop a client-centered discontinuation indicator. We build on the calculation of the client-centered discontinuation indicator by: (1) excluding switching to result in all contraceptive discontinuation (complete discontinuation); and (2) limiting discontinuation to women still in need of contraception applying the DHS definitions of in need.

使用人口和健康调查日历数据的新的以客户为中心的停药措施

方法停用数据的主要来源来自人口与健康调查 (DHS) 的日历数据。DHS 会考虑日历中女性贡献的每次使用，以计算方法停用。这意味着将仅贡献一次避孕药具使用的女性的发作与贡献多次避孕使用的女性的发作相结合。本文探讨了 DHS 对基于发作的停药的计算，并提出了专门针对客户并将她作为分析单位的新指标。首先，我们尝试通过将加权平均值应用于仅贡献一次使用的女性和贡献多次使用的女性的事件来复制 DHS 计算。然后我们计算三个以客户为中心的停药指标，使用 DHS 的五年日历数据。该方法通过使用在孟加拉国、肯尼亚和印度尼西亚收集的数据来说明。从日历中使用和报告的第一种方法开始，使用超过 12 个月后，我们开发了一个以客户为中心的停药指标。我们以客户为中心的停药指标的计算为基础：(1) 不包括转换导致所有避孕药停药（完全停药）；(2) 根据 DHS 对需要的定义，将停药限制在仍然需要避孕的女性。我们开发了一个以客户为中心的停药指标。我们以客户为中心的停药指标的计算为基础：(1) 不包括转换导致所有避孕药停药（完全停药）；(2) 根据 DHS 对需要的定义，将停药限制在仍然需要避孕的女性。我们开发了一个以客户为中心的停药指标。我们以客户为中心的停药指标的计算为基础：(1) 不包括转换导致所有避孕药停药（完全停药）；(2) 根据 DHS 对需要的定义，将停药限制在仍然需要避孕的女性。
