Disability and Health Care Expenditures among Medicare Beneficiaries

Explore the correlation between disability trends and health care costs among aging Medicare beneficiaries. Analyze spending variations based on disability status over time using a simulation model. Evaluate implications of shifting to lower disability groups for cost reduction and growth. Examine spending scenarios under disability reduction and prevention strategies.

  1. Disability and Health Care Expenditures among Medicare Beneficiaries Michael Chernew Dana Goldman Baoping Shang Feng Pan Sept. 26, 2005

  2. The Population is Aging • The number of individuals older than 65 is projected to grow rapidly • 135% between 2000 and 2050 • The number of individuals older than 85 is projected to grow rapidly • 350% between 2000 and 2050

  3. Pessimistic View • Disability rates increase with age • 0.47 among those 65-69, • 0.61 among those 75-89, • 0.82 among those 85-90. • Costs will rise due to aging and disability

  4. Optimistic view • The level of disability for any given age group has been declining over time • Controlling for age, the probability of having disability fell by 0.38% per year • The effects of aging on disability may be offset by the decline in age specific disability rates • Waidmann & Liu (2000) • Declining age specific disability rates will ameliorate disability related cost pressures

  5. Key Question • How have spending trends varied by disability status?

  6. Analysis • Estimate the relationship between disability and spending over time • Use a micro-simulation model to forecast the effects of changing disability on spending • Allow differential cost trends • Vary disability trends • Account for effects of disability on spending and longevity

  7. Adjusted Spending Growth, 1992 - 2000

  8. Implications • Shifts to low disabiity groups (non-disabled, iADL only, 1 or 2 ADL) • Reduce costs • Increase cost growth

  9. Disability scenarios • Scenario A: Reduce the prevalence among community dwelling elderly in each disability state by about 20%. • Scenario B: Prevent disability from getting worse.

  10. Per Beneficiary Spending under Different Scenarios
