Preprint
- preprint Published in RePEc
Abstract
Addresses three cost questions that commonly arise in multinational trials: (1) In countries where investigators plan to collect hospital unit cost estimates for a selected set of diagnoses, how should one estimate unit costs for the remaining diagnoses observed in the trial for which cost data were not collected? (2) For how many hospital diagnoses should estimates be obtained? (3) For how many countries should they be obtained?Keywords
