ABSTRACT
BACKGROUND:
The behavioural and psychological symptoms of dementia (BPSD) have significant negative effects on the health of both patients with dementia and their caregivers. However, the reported effectiveness of non-pharmacological interventions targeting caregivers of patients with dementia for BPSD is inconsistent.METHODS:
We systematically searched the databases PubMed, PsycINFO, CINAHL, Embase, Cochrane Library and four Chinese databases from 2010 through April 2021. The Standardised mean difference (SMD) was calculated using random-effects models. Risk of bias in individual studies was assessed using Cochrane Collaboration's tool, and the certainty of evidence was assessed using the five GRADE criteria.RESULTS:
Thirty-one randomised controlled trials (RCTs) involving 3501 dyads were included. The meta-analysis indicated that non-pharmacological interventions showed small but significant effects on both BPSD in patients with dementia (SMD = -0.14; 95% CI, -0.22 to -0.06; P = 0.001) and caregiver reactions to BPSD (SMD = -0.16; 95% CI, -0.25 to -0.07; P = 0.001). The effect sizes of BPSD in patients at follow-up (SMD = -0.24; 95% CI, -0.38 to -0.09; P = 0.002) were larger than those at post-test. Tailored interventions were associated with more substantial reductions in BPSD in patients (SMD = -0.24; 95% CI, -0.37 to -0.11; P < 0.001) than standardised interventions (SMD = -0.07; 95% CI, -0.18 to 0.04; P = 0.218).CONCLUSIONS:
Non-pharmacological interventions targeting caregivers have the potential to reduce BPSD in patients with dementia and improve caregiver negative reactions to BPSD. Moreover, tailored interventions seemed to be more effective in reducing BPSD, and more significant improvements in BPSD may be observed in long-term follow-up.Palavras-chave
