Table 5 Summary of study objectives
Aim | Articles, n[references] |
To determine whether a specific surgical procedure was cost-effective in a certain disease or dependent on certain characteristics of the cohort in which it was performed | 14[21-26,28,31-33,41,54,55,58] |
To determine whether increasing the pool of organs through various strategies was cost-effective | 26[8-11,13-18,20,34,36-41,46-52,57] |
To compare either two surgical procedures, a surgical procedure vs standard treatment, bridging treatment while on the waitlist, or an alternative treatment in order to determine which had better outcomes in terms of cost-effectiveness | 8[27,35,42-45,53,56] |
