BACKGROUND/OBJECTIVES: The impact of pain on the physical performance of patients in aged care rehabilitation is not known. The study sought to assess 1) the prevalence of pain in older people being discharged from inpatient rehabilitation; 2) the association between self-reported pain and physical performance in people being discharged from inpatient rehabilitation; and 3) the association between self-reported pain and physical performance in this population, after adjusting for potential confounding factors.
This was an observational cross-sectional study of 420 older people at two inpatient aged care rehabilitation units. Physical performance was assessed using the Lower Limb Summary Performance Score. Pain was assessed with questions about the extent to which participants were troubled by pain, the duration of symptoms, and the impact of chronic pain on everyday activity. Depression and the number of comorbidities were assessed by questionnaire and medical file audit. Cognition was assessed with the Mini-Mental State Examination.
Thirty percent of participants reported chronic pain (pain lasting more than 3 months), and 17% reported that this pain interfered with daily activities to a moderate or greater extent. Chronic pain (P=0.013) and chronic pain affecting daily activities (P<0.001) were associated with a poorer Lower Limb Summary Performance Score. The relationship between chronic pain affecting daily activities and Lower Limb Summary Performance Score remained significant (P=0.001) after adjusting for depression, age, comorbidities, and Mini-Mental State Examination score. This model explained 10% of the variability in physical performance.
One-third of participants reported chronic pain, and close to one-fifth reported that this pain interfered with daily activities. Chronic pain was associated with impaired physical performance, and this relationship persisted after adjusting for likely confounding factors.
背景/目的：疼痛对老年护理康复患者身体机能的影响尚不清楚。本研究旨在评估：1）住院康复出院的老年人中疼痛的患病率；2）住院康复出院患者自我报告的疼痛与身体机能之间的关联；3）在调整潜在混杂因素后，该人群中自我报告的疼痛与身体机能之间的关联。
这是一项对两个住院老年护理康复单元的420名老年人进行的观察性横断面研究。使用下肢综合表现评分评估身体机能。通过询问参与者受疼痛困扰的程度、症状持续时间以及慢性疼痛对日常活动的影响来评估疼痛。通过问卷调查和病历审核评估抑郁和合并症的数量。使用简易精神状态检查表评估认知能力。
30%的参与者报告有慢性疼痛（疼痛持续超过3个月），17%的参与者报告这种疼痛在一定程度上或更大程度上干扰了日常活动。慢性疼痛（P=0.013）和影响日常活动的慢性疼痛（P<0.001）与较差的下肢综合表现评分相关。在调整抑郁、年龄、合并症和简易精神状态检查表评分后，影响日常活动的慢性疼痛与下肢综合表现评分之间的关系仍然显著（P=0.001）。该模型解释了身体机能变异性的10%。
三分之一的参与者报告有慢性疼痛，近五分之一的参与者报告这种疼痛干扰了日常活动。慢性疼痛与身体机能受损相关，在调整可能的混杂因素后，这种关系仍然存在。
