Research design and methods

Five databases were searched from inception to March 21, 2025, using keyword groups related to social isolation/loneliness, older adults, and healthcare utilization (primary care, emergency visits, inpatient care, and outpatient care). Methodological quality was assessed using the Newcastle-Ottawa Scale. Random-effects models were employed to pool effect sizes (incidence rate ratios [IRRs], odds ratios [ORs]).
