RESUMO
BACKGROUND: Dementia is the seventh leading cause of global mortality, with cases increasing. Psychosocial interventions might help prevent dementia and improve quality of life. Although it is cost-effective for non-clinically trained staff to deliver these, concerns are raised and little is known about the resulting impact on staff, especially for remote interventions. AIMS: To explore how non-clinically trained facilitators experienced delivering remote, one-to-one and group-based psychosocial interventions with older adults with memory loss and their family carers, under training and supervision. METHOD: We conducted a secondary thematic analysis of interviews with non-clinically trained facilitators, employed by universities, the National Health Service and third-sector organisations, who facilitated either of two manualised interventions: the APPLE-Tree group dementia prevention for people with mild memory loss or the NIDUS-Family one-to-one dyadic intervention for people living with dementia and their family carers. RESULTS: The overarching theme of building confidence in developing therapeutic relationships was explained with subthemes that described the roles of positioning expertise (subtheme 1), developing clinical skills (subtheme 2), peer support (subtheme 3) in enabling this process and remote delivery as a potential barrier to it (subtheme 4). CONCLUSIONS: Non-clinically trained facilitators can have positive experiences delivering remote psychosocial interventions with older adults. Differences in life experience could compound initial fears of being 'in at the deep end' and 'exposed' as lacking expertise. Fears were allayed by experiencing positive therapeutic relationships and outcomes, and by growing confidence. For this to happen, appropriate training and supervision is needed, alongside accounting for the challenges of remote delivery.
RESUMO
Up to 40% of dementias may be preventable via risk factor modification. This inference has motivated the development of lifestyle interventions for reducing cognitive decline. Typically delivered to older adults face-to-face, the COVID-19 pandemic has necessitated their adaptation for remote delivery. We systematically reviewed randomized controlled trials of remotely delivered lifestyle interventions (≥4 weeks duration and delivered >50% remotely), for adults aged ≥ 60 without dementia, examining effects on objective cognitive measures. Comparators were active (face-to-face or remote) or passive. Ten studies (n = 2967) comprising multidomain (k = 4), physical activity (k = 3) or psychosocial (k = 3) remote interventions were included. Data were synthesized using robust variance estimation meta-analysis. The pooled estimate comparing the effect of remote interventions versus comparators on cognition was not significant (g=-0.02; 95%CI [-0.14, 0.09]; p = .66); subgroup analyses by type of intervention or comparator also yielded non-significant effects. Most studies had low risk of bias. Current evidence to support remote lifestyle interventions is limited. Included studies were conducted pre-pandemic, and evaluated individual, rather than group interventions. Future studies may exploit the greater digital connectivity of older people since the pandemic. Group formats, more frequently efficacious than individual interventions in face-to-face dementia prevention trials, may be a rational approach for future remote trials.
