Consistent with fear-avoidance models of falling and pain, past research has demonstrated that, among adults living in the community, excessive fear of falling and fear of pain result in activity restriction and predict functional outcomes including falls (possibly because self-imposed activity restriction, due to fear of pain or falling, can lead to muscular decline and deconditioning). Among seniors with dementia, who rely on others for their care, decisions concerning activity restrictions are made by caregivers. As such, caregivers' fear about the possibility of care recipient falls and pain is important to examine.
In this investigation of patients with dementia, our goal was to conduct a longitudinal investigation of the relationship between professional caregivers' fears (about the possibility that care recipients will experience falls and pain) with long-term care (LTC) resident functional ability and falls.
For the purposes of our 3-month longitudinal study, nurses' and special care aides' fears that specific residents might experience pain and falls were examined. Resident functional ability was assessed, based on an established and well-validated caregiver-administered questionnaire, both before and after the 3-month period. Falls and fall-related injuries sustained by residents were recorded.
After controlling for physical risk factors for falling and functional ability at the beginning of the study, caregiver fears that residents might experience pain or falls were found to be predictive of restraint/restriction use. In turn, the use of restraints/restrictions was found to be predictive of future functional ability of residents with dementia (after controlling for functional ability at the beginning of the study) and injurious falls (after controlling for physical risk factors for falling).
This is the first study to apply a modified fear-avoidance model of falls and pain to seniors with dementia who reside in LTC facilities. Our results demonstrate the importance of considering caregiver fears concerning falls and pain, when developing programs designed to optimize the use of physical restrictions (to prevent falls and minimize functional decline) in LTC facilities.
与跌倒和疼痛的恐惧回避模型一致,过去的研究表明,在社区生活的成年人中,对跌倒的过度恐惧和对疼痛的恐惧会导致活动受限,并预测包括跌倒在内的功能结局(可能是因为由于害怕疼痛或跌倒而自我施加的活动限制会导致肌肉衰退和身体机能下降)。在依赖他人照顾的老年痴呆症患者中,关于活动限制的决定由照顾者做出。因此,研究照顾者对受照顾者跌倒和疼痛可能性的恐惧很重要。
在这项对老年痴呆症患者的调查中,我们的目标是对专业照顾者的恐惧(关于受照顾者会跌倒和疼痛的可能性)与长期护理(LTC)机构居民的功能能力和跌倒之间的关系进行纵向调查。
在我们为期3个月的纵向研究中,考察了护士和特殊护理助手对特定居民可能经历疼痛和跌倒的恐惧。基于一份既定且经过充分验证的由照顾者管理的问卷,在3个月期间前后对居民的功能能力进行了评估。记录居民发生的跌倒及与跌倒相关的伤害。
在控制了研究开始时的跌倒身体风险因素和功能能力后,发现照顾者对居民可能经历疼痛或跌倒的恐惧可预测约束/限制措施的使用。反过来,发现约束/限制措施的使用可预测老年痴呆症患者未来的功能能力(在控制了研究开始时的功能能力后)和跌倒致伤情况(在控制了跌倒的身体风险因素后)。
这是第一项将改良的跌倒和疼痛恐惧回避模型应用于居住在长期护理机构的老年痴呆症患者的研究。我们的结果表明,在制定旨在优化长期护理机构中身体限制措施(以预防跌倒并尽量减少功能衰退)使用的方案时,考虑照顾者对跌倒和疼痛的恐惧很重要。
