在减肥手术后的观察性纵向研究中保留参与者是困难的，但也是关键的，因为留存率影响结果的解释和概括性。让参与者参与这类研究的策略通常不会公布。为了审查LABS保留策略并提供24个月的保留数据，LABS联盟监测了一项观察性队列研究，该研究在美国10个中心（LABS-2）纳入了2458名减肥手术前入组的成人。为了最大限度地提高数据完整性，研究者制定了保留策略，包括灵活的时间安排、电话协议、提醒信、缩短访视选项、酬金、差旅报销、提供研究进展报告、实验室结果、时事通讯、研究网站和保留调查。寻找参与者的策略包括经常更新联系信息，发送挂号信，以及搜索医疗和公共记录。在12个月和24个月时，2426和2405名参与者保持活跃，已知的生命状态分别为98.7%和97.3%，体重分别为95.2%和92.2%。24个月时有148例失访（6.2%），主要原因是无法联系受试者。在24个月时，只有15名（0.6%）活跃参与者错过了所有随访访视。虽然在6个月时无法找到或联系到42名参与者，但在12个月时获得了其中23名（54.7%）的数据，在12个月时无法找到或联系到的52名参与者中，在24个月时获得了18名（34.6%）的数据。纵向研究提供了评估减肥手术长期效果的能力。在实验室实现的保留上级许多已发表的报告，但需要大量的努力和资源。本报告确定了有用的保留策略。需要进一步研究，以确定具体的保留战略的效力和成本效益。
Retaining participants in observational longitudinal studies following bariatric surgery is difficult yet critical because the retention rate affects interpretation and generalizability of results. Strategies for keeping participants involved in such studies are not commonly published. To review LABS retention strategies and present the 24-month retention data The LABS Consortium monitors an observational cohort study of 2458 adults enrolled prior to bariatric surgery at 10 centers within the United States (LABS-2). To maximize data completeness, the investigators developed retention strategies including flexible scheduling, a call protocol, reminder letters, abbreviated visit options, honoraria, travel reimbursement, providing research progress reports, laboratory results, newsletters, study website, and retention surveys. Strategies for locating participants included frequent updates of contact information, sending registered letters, and searching medical and public records. At 12 and 24 months, 2426 and 2405 participants remained active, with vital status known for 98.7% and 97.3% and weight obtained for 95.2% and 92.2% respectively. There were 148 missed visits (6.2%) at 24 months primarily because of inability to contact the participant. Only 15 (0.6%) active participants at 24-months missed all follow-up visits. Though 42 participants could not be located or contacted at 6 months, data were obtained for 23 (54.7%) of them at 12 months, and of the 52 participants who could not be located or contacted at 12 months; data were obtained for 18 (34.6%) at 24 months. Longitudinal studies provide the ability to evaluate long-term effects of bariatric surgical procedures. The retention achieved in LABS is superior to many published reports but requires extensive effort and resources. This report identifies useful retention strategies. Further research is needed to identify the efficacy and cost effectiveness of specific retention strategies.
