Comment on Keeney et al.'s "Delphi Analysis of Relevant Comparators in a Cost-Effectiveness Model of Prostate Cancer Screening"

Keeney et al. recently published a Delphi analysis on identifying strategies for simulation in a cost-effectiveness analysis (CEA) of prostate cancer screening [1]. The research usefully elucidates the screening strategies experts consider the priority for assessment. This commentary addresses three points, the first two relate specifically to Keeney et al. regarding: (1) the questions asked of experts and (2) the sample of experts consulted. The third relates to the more general issue of how best to specify strategies in cancer screening CEAs.
