Objectives Evaluate objective isolation and loneliness’ impact on Medicare spending and outcomes. Methods We linked Health and Retirement Study data to Medicare claims to analyze objective isolation (scaled composite of social contacts and network) and loneliness (positive response to 3-item loneliness scale) as predictors of subsequent Medicare spending. In multivariable regression adjusting for health and demographics, we determined marginal differences in Medicare expenditures. Secondary outcomes included spending by setting, and mortality. Results Objective isolation predicts greater spending, $1,644(p<0.001) per beneficiary annually, whereas loneliness predicts reduced spending, −$768(p<0.001). Increased spending concentrated in inpatient and nursing-home (SNF) care; despite more healthcare, objectively isolated beneficiaries had 31%(p<0.001) greater risk of death. Loneliness did not predict SNF use nor mortality, but predicted slightly less inpatient and outpatient care. Conclusions Objectively isolated seniors have higher Medicare spending, driven by increased hospitalization and institutionalization, and face greater mortality. Policies supporting social connectedness could reap significant savings.

This category does not sum to 100 percent of participants. Total percentage represents the share of total participants (32) who reported having the chronic condition. The results may not reflect the true range of chronic conditions among the groups, as some participants may have felt uncomfortable disclosing that information in a focus group setting.
