Social Isolation and Medicare Spending: Among Older Adults, Objective Social Isolation Increases Expenditures while Loneliness Does Not.

ABSTRACT: 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.

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 heal
