Most professional medical societies sponsor clinical practice guidelines (CPGs) relevant to their clinical specialty. Previous studies report that physicians selected to serve as CPG authors have considerable industry relationships.1,2 In the field of neurosurgery, where evidence suggests that industry-funded neurosurgery trials are more likely to produce favorable results than non–industry-funded trials,3 the extent of financial conflict of interest (FCOI) among guideline authors remains unknown. In this investigation, we examined payments from medical device and pharmaceutical companies compiled in the Open Payments Database (OPD) to physician-authors of the Congress of Neurological Surgery’s (CNS) internally produced and endorsed CPGs a year before and after the CPG publication date. We also identified the portion of undisclosed payments made to authors for medications and devices relevant to CPGs.
