Show moreBackgroundOver the past decades, opioid prescriptions have increased in the Netherlands. The Dutch general practitioners’ guideline on pain was recently updated and now aims to reduce opioid prescriptions and high-risk opioid use for non-cancer pain. The guideline, however, lacks practical measures for implementation.ObjectiveThis study aims to determine practical components for a tool that should assist Dutch primary care prescribers and implements the recently updated guideline to reduce opioid prescriptions and high-risk use.MethodsA modified Delphi approach was used. The practical components for the tool were identified based on systematic reviews, qualitative studies, and Dutch primary care guidelines. Suggested components were divided into Part A, containing components designed to reduce opioid initiation and stimulate short-term use, and Part B, containing components designed to reduce opioid use among patients on long-term opioid treatment. During three rounds, a multidisciplinary panel of 21 experts assessed the content, usability, and feasibility of these components by adding, deleting, and adapting components until consensus was reached on the outlines of an opioid reduction tool.ResultsThe resulting Part A consisted of six components, namely education, opioid decision tree, risk assessment, agreements on dosage and duration of use, guidance and follow-up, and interdisciplinary collaboration. The resulting Part B consisted of five components, namely education, patient identification, risk assessment, motivation, and tapering.ConclusionsIn this pragmatic Delphi study, components for an opioid reduction tool for Dutch primary care-givers are identified. These components need further development, and the final tool should be tested in an implementation study. Show less

Show moreContext: The increased use of opioids has resulted in an unprecedented opioid epidemic. Chronic opioid use causes hypogonadism, but its frequency, as well as the effects of opioids on other hypothalamo-pituitary-end organ hormone axes, remains unclear.Objective: The aim of this systematic review and meta-analysis was to assess the effects of opioid use on pituitary function.Methods: Eight electronic databases were searched for articles published up to May 8, 2018. Fixed or random effects meta-analysis was performed to estimate pooled proportions with 95% confidence intervals (CI). This study is reported following the PRISMA and MOOSE guidelines.Data synthesis: 52 studies (22 low risk of bias) were included describing 18 428 subjects, consisting of patients with chronic pain (n = 21 studies) or on maintenance treatment for opioid addiction (n = 9) and healthy volunteers (n = 4). The most frequently used opioid was methadone (n = 13 studies), followed by morphine (n = 12). Prevalence of hypogonadism was 63% (95% CI: 55%-70%, 15 studies, 3250 patients, 99.5% males). Prevalence of hypocortisolism relying on dynamic and nondynamic testing was 15% (95% CI: 6%-28%, 5 studies, 205 patients, 57.5% males) and including only studies using the insulin tolerance tests 24% (95% CI 16%-33%, 2 studies, n = 97 patients). In 5 out of 7 studies, hyperprolactinemia was present. No clear effects on the somatotropic and hypothalamo-pituitary-thyroid axes were described.Conclusions: Hypogonadism occurs in more than half of male opioid users, and hypocortisolism in approximately one-fifth of all patients. Periodical evaluation of at least the gonadal and adrenal axes is therefore advisable. Show less
