A 9-Year Investigation of Healthcare Industry Payments to Pulmonologists in the United States.

Rationale: The healthcare industry sometimes makes payments to physicians for nonresearch and research purposes in the United States. Objectives: We aimed to evaluate the trends in nonresearch and research industry payments to pulmonologists since the inception of the Open Payments database in 2013. Methods: Using the Open Payments database between August 2013 and December 2021, this population-based observational cohort study examined nonresearch and research payments made by the healthcare industry to pulmonologists registered in the National Plan and Provider Enumeration System in the United States. We performed descriptive analyses on payment data and generalized estimating equations for payment trends. Results: Of 12,488 active pulmonologists, 11,074 (88.7%) accepted a total of 2,246,412 payments totaling $1,053,344,669. Total payments were $253,405,965 (24.1%) in nonresearch, $17,382,904 (1.7%) in direct research, and $782,555,800 (74.3%) in associated research payments between 2013 and 2021. Median per-physician payments (interquartile range) were $2,342 ($496 to $8,299) for nonresearch, $4,688 ($1,435 to $21,803) for direct research, and $95,927 ($20,300 to $344,995) for associated research payments. The top 1%, 5%, and 10% of pulmonologists accepted 37.3%, 71.9%, and 83.7% of the total nonresearch payments. The per-physician nonresearch payments increased by 2.9% (95% confidence interval [CI], 1.2 to 4.7; P  = 0.001) annually between 2014 and 2019 and decreased by 50.2% (95% CI, -55.3 to -44.6; P  < 0.001) in 2020, whereas there was no yearly change in research payments. Conclusions: Nearly 90% of pulmonologists received nonresearch and research payments from the healthcare industry in the United States. Nonresearch payments have been increasing since the inception of the Open Payments database.
