Evaluation of non-research and research industry payments to pediatric hematologist/oncologists in the United States between 2013 and 2021.

Financial interactions between healthcare industry and pediatric hematologist/oncologists (PHOs) could be conflicts of interest. Nevertheless, little is known about financial relationships between healthcare industry and PHOs. This cross-sectional analysis of the Open Payments Database examined general and research payments to PHOs from healthcare industry in the United States between 2013 and 2021. Payments to the PHOs were analyzed descriptively. Trends in payments were assessed using generalized estimating equation models. Of 2784 PHOs, 2142 (76.9%) PHOs received payments totaling $187.3 million from the healthcare industry between 2013 and 2021. Approximately, $46.3 million (24.8%) were general payments and $137.7 million (73.5%) were funding for research where PHOs served as principal investigators (associated research funding). Both general payments and associated research funding considerably increased between 2014 and 2019. The number of PHOs receiving general payments and associated research funding annually increased by 2.2% (95% CI: 1.2-3.3%, p  < .001) and 5.0% (95% CI: 3.3-6.8%, p  < .001) between 2014 and 2019, respectively.
