"Assessing the Incremental Health Care Utilization and Expenditures Associated With Serious Psychological Distress by Living Arrangements Among Older Adults." Journal of Applied Gerontology, February 26, 2025. https://doi.org/10.1177/07334648251323022.https://doi.org/10.1177/07334648251323022http://hdl.handle.net/11603/37926Older adults suffering from serious psychological distress (SPD) have higher health care utilization and expenditures. However, it is unknown whether living alone might further amplify differences in health care usage and costs among older adults with SPD. Using pooled data from 2007-2019 Medical Expenditure Panel Survey, we estimated the incremental care expenditures and utilization associated with SPD among older adults living alone and living with others. The results show that in both living arrangements, having SPD is associated with increases in emergency department visits, hospital admissions, and prescription fill-ups, which leads to higher total prescription expenditures. However, the incremental differences of SPD-related incremental usage and expenditures between older adults living alone and living with others were similar. Our findings call for targeted community programs for older adults that go beyond eliminating physical loneliness, and innovative care coordination strategies that prioritize mental health and preventative care among older adults.12 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
