Volunteer Programs Supporting People With Dementia/Delirium in Hospital: Systematic Review and Meta-Analysis

Volunteer-delivered programs to assist people with dementia and/or delirium in-hospital can provide person-centered one-on-one support in addition to usual care. These programs could mitigate hospital resource demands; however, their effectiveness is unknown. This review evaluated literature of volunteer programs in acute hospital settings for people living with dementia and/or delirium.

Four databases were searched. Studies that reported patient or program outcomes were included (i.e., delirium incidence, length of stay, number of falls, satisfaction). Risk of bias was completed. Meta-analysis was performed where 2 or more studies measured the same outcome. Narrative synthesis was performed on the qualitative results.

Eleven studies were included in the review, with varied design, participant groups and outcomes measured. Risk of bias averaged 71%. Volunteer-delivered programs addressed delirium risk factors, for example, hydration/nutrition, mobility, use of sensory aids. Eight patients and 6 program outcomes were captured, but only 3 patient outcomes could be pooled. Meta-analyses demonstrated a reduction in delirium incidence (rate ratio = 0.65; 95% confidence interval [CI] 0.47, 0.90) but no reduction in length of stay (mean difference -1.09; 95% CI -0.58, 2.77) or number of falls (rate ratio = 0.67; 95% CI 0.19, 2.35). Narrative synthesis identified benefits to patients (e.g., less loneliness), volunteers (sense of meaning), and staff (timesaving, safety).

Volunteer-delivered programs for inpatients with dementia and/or delirium may provide benefits for patients, volunteers, and staff. However, studies conducted with more robust designs are required to determine overall effectiveness on program outcomes. Further high-quality research appropriate for this vulnerable population is required to identify volunteer program effectiveness.
