Orthopaedic trauma studies that collect long-term outcomes are expensive and maintaining high rates of follow-up can be challenging. Knowing what factors influence completion of follow-up could allow interventions to improve this. We aimed to assess which factors influence completion of follow-up in the 12 months following surgery in prospective orthopaedic trauma research.
Prospective Cohort Study.
Level 1 Trauma Center, Vancouver, Canada.
Eight hundred seventy patients recruited to 4 prospective studies investigating the outcomes of operatively treated lower extremity fractures.
Completion of follow-up defined as completion of all outcome measures at all time points up to 12 months following injury.
Univariate analysis and subsequent analysis by building a reductive multivariate regression model allowed for estimation of the influence of factors in completion of follow-up.Eight hundred seventy patients with complete data had previously been recruited and were included in the analysis. Seven hundred seven patients (81.2%) completed follow-up to 12 months. Factors associated with completion of follow up included higher physical component score of SF-36 at baseline, not being on social assistance at the time of injury, being married and having a higher level of educational attainment.
Our study has demonstrated several important factors identifiable at baseline which are associated with a failure to complete follow-up. Although these factors are not modifiable themselves, we advocate that researchers designing studies should plan for additional follow-up resources and interventions for at risk patients.

收集长期结果的骨科创伤研究成本高昂，维持高随访率具有挑战性。了解哪些因素会影响随访的完成情况，有助于采取干预措施加以改善。我们旨在评估在前瞻性骨科创伤研究中，哪些因素会影响术后12个月内随访的完成情况。
前瞻性队列研究。
加拿大温哥华一级创伤中心。
870名患者参与了4项前瞻性研究，这些研究旨在调查手术治疗下肢骨折的结果。
随访完成情况定义为在受伤后12个月内的所有时间点完成所有结局指标。
单因素分析以及随后通过构建简化多元回归模型进行的分析，有助于评估各因素对随访完成情况的影响。870名拥有完整数据的患者此前已被招募并纳入分析。707名患者（81.2%）完成了12个月的随访。与随访完成相关的因素包括基线时SF-36身体成分得分较高、受伤时未领取社会救助、已婚以及受教育程度较高。
我们的研究表明，在基线时可识别出几个与随访未完成相关的重要因素。尽管这些因素本身无法改变，但我们建议研究设计者应为有风险的患者规划额外的随访资源和干预措施。
