Good summary of key success factors in aging in place technologies in the current McKinsey Quarterly.
"In the United States, home care accounts for about 3 percent ($68 billion a year) of national health spending. The market is increasing by about 9 percent annually, solid but hardly booming growth, especially since labor (mainly nurses and aides) accounts for about two-thirds of the expenditure and home-monitoring technology represents a small fraction of it. What’s holding the market back? We observe a daunting array of financial and operational barriers, including the misalignment of incentives between payers and providers, the need to demonstrate a strong clinical value proposition, and the problem of designing attractive, easy-to-use products that facilitate adoption by patients."
They boil them down to financial, effectiveness and accessibility factors:
1. Alignment between payers and providers.
2. Remunerative. (return on investment)
3. Having significant impact.
6. Closed loop. (to verify whether effective actions or treatments actually occurred).
