Sarcopenia is prevalent in 20-50% of geriatric rehabilitation inpatients, but it is often undiagnosed.
The aim of the study is to evaluate the feasibility of bioelectric impedance analysis (BIA) to measure muscle mass in routine clinical care in a cohort of geriatric rehabilitation inpatients.
REStORing Health of acutely unwell adulTs (RESORT) is an observational, longitudinal inception cohort of geriatric rehabilitation inpatients. BIA was implemented at admission and discharge as routine care performed by nursing staff. BIA feasibility was defined as completion rate (low ≤ 25%, moderate > 25- ≤ 50%, good > 50- ≤ 75%, excellent > 75%), reasons for non-completion and need for remeasurement. Clinical characteristics associated with BIA completion and remeasurements were assessed.
Patients (n = 1890, 56% females) had a median age of 83.4 years (interquartile range: [77.6-88.4]). Of the total cohort, 5.7% had a contraindication (pacemaker/other electronic medical device) for BIA at admission and 4.5% at discharge. BIA was completed in 77.1% of patients eligible for BIA at admission and 63.2% at discharge indicating good feasibility; remeasurement was required in 7.4 and 6.9%, respectively; 5.9% had a medical reason preventing BIA completion at admission and 3.7% at discharge. Refusal and technical issues occurred in 1.6 and 0.7% at admission and 2.1 and 1.8% at discharge. Reason for non-completion was unknown/missing in 14.7% at admission and 28.6% at discharge. Worse functional and physical performance was associated with BIA non-completion and remeasurement.
BIA in routine clinical care in geriatric rehabilitation inpatients is feasible; completion rates may be enhanced further by reviewing barriers and enablers.
肌肉减少症在20%至50%的老年康复住院患者中普遍存在，但往往未被诊断出来。
本研究的目的是评估生物电阻抗分析（BIA）在一组老年康复住院患者的常规临床护理中测量肌肉质量的可行性。
急性不适成人健康恢复（RESORT）是一项针对老年康复住院患者的观察性纵向起始队列研究。BIA在入院时和出院时作为护理人员进行的常规护理实施。BIA的可行性定义为完成率（低≤25%，中等>25%至≤50%，良好>50%至≤75%，优秀>75%）、未完成的原因和重新测量的需求。评估与BIA完成和重新测量相关的临床特征。
患者（n = 1890，56%为女性）的中位年龄为83.4岁（四分位间距：[77.6 - 88.4]）。在整个队列中，5.7%的患者在入院时因BIA有禁忌症（起搏器/其他电子医疗设备），4.5%在出院时存在该情况。符合BIA条件的患者中，77.1%在入院时完成了BIA，63.2%在出院时完成，表明可行性良好；分别有7.4%和6.9%的患者需要重新测量；5.9%的患者在入院时有医学原因导致无法完成BIA，3.7%在出院时存在该情况。入院时拒绝和技术问题发生率分别为1.6%和0.7%，出院时为2.1%和1.8%。入院时14.7%、出院时28.6%未完成的原因不明/缺失。功能和身体表现较差与BIA未完成和重新测量有关。
在老年康复住院患者的常规临床护理中进行BIA是可行的；通过审查障碍因素和促进因素，完成率可能会进一步提高。
