Hematopoietic cell transplantation (HCT) practices vary widely among physicians globally. This heterogeneity in decision-making for HCT treatments underscores the need for further clinical trials and evidence-based guidelines.
Area of Science:
- Hematology
- Transplant Medicine
- Clinical Practice Variation
Background:
- Previous research has examined practice variations in hematopoietic cell transplantation (HCT) at institutional and national levels.
- However, individual physician practice variation in HCT remains understudied.
Purpose of the Study:
- To investigate and quantify practice variation among individual transplant physicians in HCT.
- To identify factors influencing medical decision-making in HCT.
Main Methods:
- An international, internet-based survey was administered to adult and pediatric HCT physicians.
- Data on clinical decisions were collected and analyzed using multivariable analyses to identify predictive characteristics of practitioners and transplant centers.
Main Results:
- A significant variation in management approaches was observed across 526 respondents for specific clinical scenarios.
- Pediatric and adult HCT physicians demonstrated differing strategies for chronic myeloid leukemia, graft-versus-host disease, and graft source selection for aplastic anemia.
- Limited consensus existed among adult HCT physicians regarding conditioning regimens (reduced intensity vs. myeloablative).
Conclusions:
- The findings highlight substantial heterogeneity in global HCT practices, suggesting local preferences influence treatment decisions.
- The observed practice variation emphasizes the necessity for clinical trials to resolve controversial areas in HCT.
- In the absence of clinical trials, observational study data may serve as the best available evidence to guide HCT practice.
