在服务点提供的健康行为干预包括那些将干预协议与现有护理系统结合在一起的干预措施（例如，临床护理、社会工作或个案管理）。虽然在许多方面是有益的，但这种“托管”干预研究可能无法留住那些特别停止使用托管服务的参与者。鉴于最近的做法使用总流失百分比作为方法缺陷的指标，针对难以接触到的人群的托管干预措施可能被排除在有效干预措施简编或研究综合的考虑之外，因为高流失率实际上可能是服务使用的自然流动的次要因素，或者与差异流失或内部设计缺陷无关。需要更好的方法来描述严格性。(Am J公共卫生。2009;99：1567-1575. doi：10.2105/AJPH.2008.134767）
Health behavior interventions delivered at point of service include those that yoke an intervention protocol with existing systems of care (e.g., clinical care, social work, or case management). Though beneficial in a number of ways, such "hosted" intervention studies may be unable to retain participants that specifically discontinue their use of the hosting service. In light of recent practices that use percent total attrition as indicative of methodological flaws, hosted interventions targeting hard-to-reach populations may be excluded from consideration in effective intervention compendiums or research synthesis because of high attrition rates that may in fact be secondary to the natural flow of service use or unrelated to differential attrition or internal design flaws. Better methods to characterize rigor are needed. (Am J Public Health. 2009;99: 1567-1575. doi:10.2105/AJPH.2008.134767)
