Annual Per-Patient Cost-Utility Ratios Associated With ATSM Relative to Usual Care
| Cost-Utility Ratio, $ per QALY Gaineda | ||
|---|---|---|
| Model | Analysis | Sensitivity Analysisb |
| ATSM=Automated telephone self-management support; QALY=quality-adjusted life-year. | ||
| Notes: Cost savings were not evaluated; QALYs were estimated from scores on the 12-Item Short Form Health Survey. | ||
| a This ratio was calculated as (cost of ATSM)/(QALY for ATSM – QALY for usual care). | ||
| b This analysis tested a 10% variation in the estimated QALY gain of 0.012 associated with ATSM in both directions: a 10% decrease to 0.0108 and a 10% increase to 0.0132. | ||
| Model A (start-up+ongoing costs) | 65,167 | With 10% decrease in QALY gain: 72,407 With 10% increase in QALY gain: 59,242 |
| Model B (ongoing costs only) | 32,333 | With 10% decrease in QALY gain: 35,926 With 10% increase in QALY gain: 29,402 |
