Neuropsychiatric symptoms (NPS) are highly prevalent in Alzheimer's disease (AD) and are associated with negative outcomes. However, NPS are currently underrecognized at the memory clinic and non-pharmacological interventions are scarcely implemented.
To evaluate the effectiveness of the Describe, Investigate, Create, Evaluate (DICE) method™ to improve the care for NPS in AD at the memory clinic.
We enrolled sixty community-dwelling people with mild cognitive impairment or AD dementia and NPS across six Dutch memory clinics with their caregivers. The first wave underwent care as usual (n = 36) and the second wave underwent the DICE method (n = 24). Outcomes were quality of life (QoL), caregiver burden, NPS severity, NPS-related distress, competence managing NPS, and psychotropic drug use. Reliable change index was calculated to identify responders to the intervention. A cost-effectiveness analysis was performed and semi-structured interviews with a subsample of the intervention group (n = 12).
The DICE method did not improve any outcomes over time compared to care as usual. Half of the participants of the intervention group (52%) were identified as responders and showed more NPS and NPS-related distress at baseline compared to non-responders. Interviews revealed substantial heterogeneity among participants regarding NPS-related distress, caregiver burden, and availability of social support. The intervention did not lead to significant gains in quality-adjusted life years and well-being years nor clear savings in health care and societal costs.
The DICE method showed no benefits at group-level, but individuals with high levels of NPS and NPS-related distress may benefit from this intervention.
神经精神症状(NPS)在阿尔茨海默病(AD)中非常普遍,与不良后果相关。然而,NPS 在记忆诊所中目前未得到充分识别,且很少实施非药物干预。
评估描述、调查、创造、评估(DICE)方法™在改善 AD 记忆诊所 NPS 护理方面的效果。
我们招募了 60 名患有轻度认知障碍或 AD 痴呆症且伴有 NPS 的社区居民及其照顾者,来自六个荷兰记忆诊所。第一波接受常规护理(n=36),第二波接受 DICE 方法(n=24)。结果为生活质量(QoL)、照顾者负担、NPS 严重程度、NPS 相关痛苦、管理 NPS 的能力以及精神药物使用。计算可靠变化指数以确定对干预的反应者。进行了成本效益分析,并对干预组的一个亚样本(n=12)进行了半结构化访谈。
与常规护理相比,DICE 方法在任何时间点都未改善任何结果。干预组的一半参与者(52%)被确定为反应者,与非反应者相比,他们在基线时具有更高的 NPS 和 NPS 相关痛苦。访谈显示,参与者在 NPS 相关痛苦、照顾者负担和社会支持可用性方面存在很大的异质性。该干预措施并未导致在质量调整生命年和幸福年方面获得显著收益,也未明显节省医疗保健和社会成本。
DICE 方法在群体水平上没有显示出益处,但患有高 NPS 和 NPS 相关痛苦的个体可能会从这种干预中受益。
