a community health worker program to support rural older adults

Conditions: Frail Elderly; Cognitive Impairment; Mobility Limitation; Depressive Symptoms

Summary: this study will investigate an intervention delivered by community health workers for older adults with signs of cognitive impairment, mobility loss, and depression in the rural primary care setting.

the population of the united states is aging rapidly, and the populations of vermont (vt), new hampshire (nh), and maine (me) are among the oldest in the nation. there is a need to develop and disseminate interventions to prevent functional decline in older adults, defined as difficulty completing daily activities independently. cognitive impairment, depressive symptoms, and mobility loss are three common syndromes identified in primary care that contribute to functional decline in older adults. evidence-based interventions can address early stages of these three conditions; however older adults in rural communities may have particular difficulty accessing interventions due to limited health and social services. community health workers (chws) offer a potential strategy to address gaps in care and deliver interventions to vulnerable older adults in rural communities. the overarching goal of this study is to conduct a pilot investigation of a chw-delivered intervention to slow progression of functional decline among at-risk older adults. using qualitative and quantitative methods, this pilot study will: 1) evaluate whether a multicomponent intervention delivered by chws for rural older adults at risk for functional decline is feasible to deliver and acceptable to older adults and their primary care teams; and 2) explore the effectiveness of combined tai ji quan: moving for better balance (tjqmbb), behavioral activation (ba), and resource navigation in slowing functional decline among older adults with co-occurring early impairments in cognition, mood, and mobility. older adults who are at high risk for functional decline will be recruited from partnering primary care sites (two intervention sites in vt and me, and one comparison site in nh) based on results from the medicare annual wellness visit (awv), which incorporates screening for cognitive impairment, depression, and falls risk, as well as provider referral and chart review. chws will be trained to deliver a 6-month intervention incorporating two evidence-based interventions that target cognition, depressive symptoms, and mobility (tjqmbb and behavioral activation), and resource navigation to address unmet social needs that may create barriers. feasibility, acceptability, and potential effectiveness will be assessed through a combination of qualitative interviews, standardized questionnaires, physical measurements, and surveys.
