Key result
Early postoperative blood transfusion is linked to a ~1.8-point lower 3-day Cumulated Ambulation Score.
Why the study?
Factors influencing the three-day postoperative Cumulated Ambulation Score in older adults with proximal hip fractures were not well understood.
Observational (n=299)
No
Pre-injury physical function and perioperative general condition, such as blood transfusion and surgical procedure, significantly affect early postoperative mobility in older adults with hip fractures.
Associated factors may inform risk stratification after hip fracture; hypothesis-generating and requires prospective confirmation before practice change.
〔目的〕高齢大腿骨近位部骨折患者における術後3日間の Cumulated Ambulation Score（3-day CAS）に影響する因子を明らかにする．〔対象と方法〕対象は，大腿骨近位部骨折患者299例とした．重回帰分析を用いて3-day CASに影響する因子を分析した．〔結果〕術後3日間の輸血の有無，術式，入院前の運動項目Functional Independence Measureが検出された．〔結語〕3-day CASの得点には，受傷前の身体機能や周術期の全身状態が反映されていた．

Toriyama et al. (2025) conducted an observational in Proximal hip fractures (n=299). Blood transfusion during the first 3 postoperative days vs. No blood transfusion was evaluated on 3-day postoperative Cumulated Ambulation Score (3-day CAS) (MD -1.83, 95% CI -2.42 to -1.24, p=<0.01). Blood transfusion during the first 3 postoperative days (MD -1.83), surgery type, and pre-admission motor FIM score were independently associated with the 3-day postoperative Cumulated Ambulation Score.
