- Registration Number
- NCT04809051
- Lead Sponsor
- Carnegie Mellon University
- Brief Summary
This empirical study tests whether transplant center performance data that reflect center donor acceptance rates influence patients and their family members to evaluate centers with high organ decline rates less favorably than centers with low organ decline rates. 400 transplant patients and family members will be recruited from transplant support group social media websites and randomized to one of four different information presentation conditions. Upon viewing a pair of outcome tables corresponding to their condition, the participants are asked to choose which hospital is higher performing (one hospital with a non-selective "accepting" strategy and one hospital with a more selective "cherrypicking" strategy.

Group Intervention Description Condition 3: Combined Transplant SRTR SRTR Information Format Participants randomized to Condition 3 will view only combined transplant survival outcome information (e.g. transplant survival rate not stratified by number and quality of donor hearts accepted at each center) when making a choice between the two hospitals. The "survival following transplant" metric is displayed as a quintile score corresponding to all patients at the center who received transplants. Condition 4: Stratified Transplant SRTR Stratified Transplant Survival Metric Participants randomized to Condition 4 will view only stratified transplant survival outcome information when making a choice between the two hospitals. The "survival following transplant" metric is displayed as a pair of quintile scores corresponding to two distinct groups of transplant patients at the center: those who received optimal donor organs and those who received adequate donor organs. Condition 2: Stratified Transplant Pictograph Stratified Transplant Survival Metric Participants randomized to Condition 2 will view only stratified transplant survival outcome information when making a choice between the two hospitals. The "survival following transplant" metric is displayed as a pair of survival rate pictographs corresponding to two distinct groups of transplant patients at the center: those who received optimal donor organs and those who received adequate donor organs. Condition 4: Stratified Transplant SRTR SRTR Information Format Participants randomized to Condition 4 will view only stratified transplant survival outcome information when making a choice between the two hospitals. The "survival following transplant" metric is displayed as a pair of quintile scores corresponding to two distinct groups of transplant patients at the center: those who received optimal donor organs and those who received adequate donor organs.
- Primary Outcome Measures
Name Time Method Hospital Choice 1 day The outcome variable will be a measure of binary choice between two hospitals: one with a selective donor-heart acceptance strategy and one with a non-selective donor heart acceptance strategy.
Participants will respond to the question "Which Hospital is higher performing? Please click on one of the two tables below to indicate which hospital is the better choice." Participants will choose been two outcome tables featuring the selective and non-selective hospital (counterbalanced, such that each of the two choices is equally likely to be presented at top of the choice scenario in each condition). The number of participants that choose each hospital will be the measured outcome variable used in analyses.
- Secondary Outcome Measures
Name Time Method Mediator of Hospital Choice 1 day On the next page of the survey, participants will respond to three mediator questions: "There are many reasons why one transplant hospital might outperform another. Which reasons were most important in your decision? Please move the slider to indicate how much you considered each of the reasons below (0=reason was not important, 100=reason was extremely important)."
Participants will then move a slider bar (0-100) to indicate the importance of the following three items:
Patients were more likely to receive an excellent donor heart at the hospital I picked.
Patients were less likely to receive a marginal donor heart at the hospital I picked.
Patients were more likely to receive any kind of heart at the hospital I picked.
The third item (more likely to receive any kind of heart) will be the only variable that is included in the planned mediation analysis.
