Abstract
Objective: Opioid-induced adrenal insufficiency (OIAI) is reported in up to 29% of chronic opioid users through suppression of the hypothalamus-pituitary-adrenal axis. Unrecognized adrenal insufficiency leads to increased morbidity and potentially death; thus, healthcare provider (HCP) awareness of OIAI is crucial. The aim of the present study was to assess the knowledge and current practices of HCPs regarding OIAI and to identify factors associated with decreased awareness. Methods: We carried out a cross-sectional, anonymous survey of HCPs in internal medicine specialties that prescribe or care for patients taking chronic opioids. Results: Of 91 (30%) participants who completed the survey, 51 (56%) were men and 52 (57%) were in training. Most responders were general internal medicine providers (n = 33, 36%), followed by endocrinologists (n = 13, 14%) and various other specialties (n = 45, 49%). While 61 (67%) of respondents prescribed opioids, only 17 (19%) were comfortable in their knowledge of opioid side effects. Among nonendocrine providers, 53 (68%) identified adrenal insufficiency as a known opioid-induced endocrinopathy. Compared to other providers, endocrinologists were more likely to recognize opioid-related endocrinopathies (69% versus 24%, P = .01) and to identify the correct symptoms for OIAI (38% versus 9%, P <.001). One in four nonendocrine providers reported discomfort in managing glucocorticoid replacement therapy. The majority (60%) of providers indicated that online resources and continuing medical education lectures would improve knowledge of OIAI. Conclusion: Our study identified several deficiencies in HCP knowledge of opioid-induced endocrine effects, especially in nonendocrine providers. As many symptoms of OIAI overlap with those of underlying conditions, OIAI could be potentially missed, highlighting the need to further educate providers about opioid-induced endocrinopathies. Abbreviations: ACTH = adrenocorticotropic hormone; AI = adrenal insufficiency; CME = continuing medical education; HCP = healthcare professional; OIAI = opioid-induced adrenal insufficiency.
