Parameter | Description | Value/Distribution | Study Design to Provide Further Information |
---|---|---|---|
Effect of albumin on mortality | Posterior distribution generated by Bayesian evidence synthesis model | RCT including albumin and control arm | |
Effect of saline on mortality | Posterior distribution generated by Bayesian evidence synthesis model | RCT including saline and control arm | |
Effect of gelofusine on mortality | Posterior distribution generated by Bayesian evidence synthesis model | RCT including gelofusine and control arm | |
dS | Change to NS risk in “saved” patients | Posterior distribution generated by Bayesian evidence synthesis model | RCT including fluid resuscitation arm(s) and control arm |
Fluid cost (per patient) | $1 (saline), $35 (albumin), $12.50 (gelofusine) | ||
Additional in-patient costs associated with survival | $60 (based on 5 d at $12/d) | ||
Log-odds of death without fluid resuscitation | Normal with implied median probability of death 25%, 95% CI 15%–40% | Cohort study with short-term follow-up | |
Probability of NS without fluid resuscitation | Beta (1,9) (mean 10%, 95% CI 0.6%–28.5%) | Cohort study with 28-d follow-up | |
Probability that NS will still be present at 6 mo conditional on NS observed at 28 d | Beta (1,1) | Cohort study with 6-mo follow-up | |
Long-term discounted costs of NS | $20 000 | ||
QALY loss per fatality | Normal with CHAR1 = 20 and s = 5 | Cohort study on survivors without NS: long-term follow-up | |
QALY loss per case of NS | Truncated normal with CHAR1 = 5, s = 3.16, lower limit = 0 | Cohort study on those with NS: long-term follow-up |
Note: CI = confidence interval; NS = neurological sequelae; QALY = quality-adjusted life-year; RCT = randomized controlled trial.
