The purpose of this study was to examine group differences in verbal agitation, verbal interaction, bed restraint, pain, analgesic and neuroleptic medication use, and medical comorbidity among agitated nursing home residents who died during a 6-month clinical trial compared with residents of the same gender and similar initial cognitive status who did not die during the trial.
We conducted a two-group secondary data analysis of prospective observational data from 10 nursing homes in Birmingham, Alabama. By means of chart review, resident assessments, surveys of certified nursing assistants, and direct observation of residents' daily behaviors and environment, 32 residents (87.34 +/- 7.29 years) with a Mini-Mental State Examination (MMSE) score = 4.31 (+/-5.54) who died were compared with 32 residents (84 +/- 6.96 years) with a mean MMSE score = 4.28 (+/-5.49) who did not die during the clinical trial.
Residents who died displayed more verbal agitation, less time in verbal interaction with staff, and almost twice as much time restrained in bed during observation time in comparison with residents who did not die during the clinical trial. However, groups did not differ significantly in severity of comorbid illness, functional status, number of painful diagnoses, certified nursing assistants' reports of residents' pain, or opioid or nonopioid analgesic prescription or dosage. Surviving residents were more likely to receive neuroleptic medication than residents who died.
Results suggest that agitated nursing home residents may exhibit a heightened level of verbal agitation, decreased verbal interaction with staff, and increased bed restraint up to 3 months prior to death. Prospective observational studies are needed to identify markers for imminent mortality among nursing home residents.
本研究旨在比较在为期6个月的临床试验期间死亡的躁动不安的疗养院居民与在试验期间未死亡的、性别相同且初始认知状态相似的居民在言语激越、言语互动、床上约束、疼痛、镇痛和抗精神病药物使用以及医疗合并症方面的组间差异。
我们对来自阿拉巴马州伯明翰市10家疗养院的前瞻性观察数据进行了两组二次数据分析。通过病历审查、居民评估、对注册护理助理的调查以及对居民日常行为和环境的直接观察,将32名死亡居民(年龄87.34±7.29岁,简易精神状态检查表(MMSE)评分=4.31(±5.54))与32名在临床试验期间未死亡的居民(年龄84±6.96岁,平均MMSE评分=4.28(±5.49))进行比较。
与在临床试验期间未死亡的居民相比,死亡居民表现出更多的言语激越,与工作人员进行言语互动的时间更少,并且在观察期间被约束在床上的时间几乎是未死亡居民的两倍。然而,两组在合并症严重程度、功能状态、疼痛诊断数量、注册护理助理报告的居民疼痛情况或阿片类或非阿片类镇痛药物的处方或剂量方面没有显著差异。存活居民比死亡居民更有可能接受抗精神病药物治疗。
结果表明,躁动不安的疗养院居民在死亡前3个月可能表现出更高水平的言语激越、与工作人员言语互动减少以及床上约束增加。需要进行前瞻性观察研究以确定疗养院居民即将死亡的标志物。
