Variation between economic evaluations in baseline parameter estimates*
| Baseline parameters | No. times identified as key parameter | No. different estimates | Minimum estimate | Maximum estimate | Median estimate |
|---|---|---|---|---|---|
| Epidemiologic | |||||
| Incidence of CR-BSI | 6/8 | 8/8 | 3.1% | 8.0% | 5.3% |
| Effectiveness of the intervention | 6/8 | Will vary according to intervention | |||
| Attributable mortality | 2/7 | 5/7 | 5% | 15% | 14% |
| Incidence of localized insertion site infection | 0/5 | 4/5 | 5% | 50% | 20% |
| Cost | |||||
| Cost of CR-BSI | 6/8 | 6/8 | US $2,820 | US $13,000 | US $10,531 |
| Cost of localized insertion site infection | 0/5 | 3/5 | US $195 | US $435 | US $280 |
| Cost of intervention | 2/8 | Will vary according to intervention | |||
| Cost of other complications | 1/3 | Will vary according to complications considered | |||
*All cost estimates adjusted to 2005 US dollars. Values for parameters are the baseline estimate used in the model (the same patterns of variation were observed with the ranges used for sensitivity analysis). CR-BSI, catheter-related bloodstream infections.
