The trustworthiness and transparency in clinical practice guidelines versus the ongoing damaging power of direct and indirect conflict of interest

With the increasing costs of health care, clinical practice guidelines (CPGs) have gained a crucial role in standardizing care, protecting health resources, and assuring their accurate distribution by improving health outcomes. Influencing the outcome of a guideline (by one of the authors, members of the specialty board, or an influential member of the specialty) could result in inappropriate expense to the health care system and profits to investors of the medications/tests/devices that were recommended. CPGs are statements based on a systematic review of the existing scientific evidence, developed by knowledgeable experts, that have the potential to reduce inappropriate practice variation, enhance research, and improve health care quality and safety.(1) (C) 2020 Elsevier Inc.
