研究问题
Retrospective cohort study using linked administrative medical and long-term care insurance claims.；Longer initial claims-based rehabilitation continuity during the postoperative 6 months was associated with a lower incidence of subsequent nonfatal worsening (adjusted subdistribution hazard ratio per month, 0.961; 95% CI, 0.941-0.982).；Longer initial claims-based rehabilitation continuity was associated with lower incidence of nonfatal worsening but should be interpreted as a claims-based association, not evidence of a causal effect or mortality-inclusive benefit.
方法
Retrospective cohort study using linked administrative medical and long-term care insurance claims.；The day-180 landmark cohort included 6556 patients who survived to day 180 and were not certified as care-need level 5 before surgery or at the landmark.
核心结论
To describe 3-year transitions of care-need level after hip fracture surgery and identify factors associated with subsequent nonfatal worsening among day-180 survivors.；Longer initial claims-based rehabilitation continuity during the postoperative 6 months was associated with a lower incidence of subsequent nonfatal worsening (adjusted subdistribution hazard ratio per month, 0.961; 95% CI, 0.941-0.982).；Associations of higher Hospital Frailty Risk Score and preoperative care-need levels with worsening varied over time.；Longer initial claims-based rehabilitation continuity was associated with lower incidence of nonfatal worsening but should be interpreted as a claims-based association, not evidence of a causal effect or mortality-inclusive benefit.
局限
Longer initial claims-based rehabilitation continuity was associated with lower incidence of nonfatal worsening but should be interpreted as a claims-based association, not evidence of a causal effect or mortality-inclusive benefit.
对本项目的价值
人群纵向证据，可用于假说生成与终点选择：功能结局（衰弱 / 肌少症）是临床转化最可及的终点，适合作为一期终点候选。 ｜ 价值分 1.6/5（★★☆☆☆）

本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
