A proactive phone intervention for older adults to address loneliness identified by a health plan.

Social isolation and loneliness are associated with poor health and higher health care costs among older adults. Our objective was to determine if older adults identified as at risk for loneliness by a Medicare Advantage health plan could benefit from a proactive telephone support program. We conducted a mixed-methods pilot efficacy study of outbound calls from an established community-based telephone program to support older adults identified as at risk for loneliness.
