Sixty percent of US physicians serving as panel and task force members for the American Psychiatric Association's official manual of psychiatric disorders received payments from industry totalling $14.24m, finds a study published by The BMJ. Because of the enormous influence of diagnostic and treatment guidelines, the researchers say their findings "raise questions about the editorial independence of this diagnostic manual." Often referred to as the 'bible' of psychiatric disorders, the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, text revision (DSM-5-TR) is the latest edition of the guide that doctors use to diagnose and treat patients. It is thus critical that authors of this psychiatric taxonomy should be free of industry ties. But until the development of Open Payments ... it wasn't possible to determine the amount of monies received by authors of diagnostic and clinical practice guidelines. Their analysis included 92 physicians based in the US who served as members of either a panel (86) or task force (6) on the DSM-5-TR from 2016-19. Of these 92 individuals, 55 (60%) received payments from industry. Collectively, these panel members received a total of $14.24m (£11.21m; €12.96m). The most common types of payment were for food and beverages (91%), followed by travel (69%) and consulting (69%). The greatest proportion of compensation by category of payment was for research funding (70%). To ensure unbiased, evidence based mental health practice, there should be a rebuttable presumption of prohibiting financial conflicts of interest among the panel and task force members.
