Hypothesis
Is the Advancing Better Living for Elders (ABLE) intervention cost-effective for functionally vulnerable older adults?
Conclusion
The ABLE intervention is cost-effective, with an incremental cost-effectiveness ratio of $13,179 to $14,800 per additional year of life.
Supporting Evidence
- The ABLE intervention reduced functional difficulties and mortality in older adults.
- The cost for the ABLE intervention was $942 per participant.
- Probabilistic sensitivity analyses indicated the cost-effectiveness of ABLE under various scenarios.
Takeaway
This study looks at a program that helps older people stay at home and found that it can be worth the money spent because it helps them live longer.
Methodology
The study used a cost-effectiveness analysis based on a randomized trial comparing the ABLE intervention to a control group.
Potential Biases
The cost estimates may overestimate the actual costs due to the retrospective nature of the analysis.
Limitations
The study did not capture quality-adjusted life years (QALYs) and was conducted post hoc, which may limit the accuracy of cost estimates.
Participant Demographics
Participants were 70 years or older, cognitively intact, and living at home with functional difficulties.
