- •We sought to determine parameter estimates made in cost-effectiveness analyses (CEAs) in prostate cancer and identified 508 model estimates.
- •We noted substantial heterogeneity in parameter estimates made across CEAs.
- •To assess the impact of this heterogeneity, we constructed a Markov cohort model using the parameters we identified from our systematic review, which demonstrated 3 separate acceptability determinations.
- •Such variation suggests that the parameter estimates underlying individual CEAs must be considered carefully before altering clinical management decisions or health policy.
