Objective: This study assessed home health care use associated with Alzheimer's Disease and related dementias (ADRD) in US community dwelling older adults, including workforce, intensity, and cost outcomes.
Materials and methods: Medical Expenditure Panel Survey (2010-2018) household and home care event files were used to identify adults ≥ 65 years with ADRD. Outcomes included home health care provider type, intensity of care use, and annual direct home care cost. All analyses applied person weights for national estimates.
Results: Among the 20,443 eligible older adults, 4.2% (n = 843) reported ADRD. Among all professional and non-professional health care workers, nurse practitioners (NPs, 38.5%) and home health care aids (35.6%) were most used. Comparing ADRD vs non-ADRD: the annual per-person average number of days in home care was 110 vs. 64 (p<0.001) and home care costs accounted for 30.8% vs. 7.5% of total health care costs. After adjusting for participants' characteristics, those with ADRD were more likely to use home health care (OR = 4.32, 95% CI=3.29 - 5.68) and showed 229% (95% CI = 175% - 297%) higher associated costs than controls (p<0.001).
Conclusion: The study provides insight into the home care workforce. Of the professional workforce NPs were most often used and home care aides dominated the non-professional workforce. As expected, ADRD increased the likelihood and intensity of home health care utilization and associated direct home care costs significantly.
