A European multicentre drug utilisation study of the impact of regulatory measures on prescribing of codeine for pain in children.

ABSTRACT: PURPOSE:In June 2013, following recommendations from the World Health Organization (WHO) and Food and Drug Administration (FDA), the European Medicines Agency agreed updates to the codeine product information regarding use for pain in children younger than 12 years and children undergoing tonsillectomy or adenoidectomy (TA) for obstructive sleep apnoea. This study was conducted to (a) assess effectiveness of these measures on codeine prescribing in the "real-world" setting and (b) test feasibility of a study using a common protocol by regulators with access to databases. METHODS:The study was performed using BIFAP (Spain), CPRD (UK), and IMS® Disease Analyzer (France and Germany) databases. Prescribers included general practitioners (GPs) (France and UK), GPs and paediatricians together (Spain), and GPs, paediatricians, and ear, nose, and throat (ENT) specialists separately (Germany). Between January 2010 and June 2015, prevalence of codeine prescribing was obtained every 6 months, and a time series analysis (joinpoint) was performed. Codeine prescribing within ±30 days of TA was also identified. Furthermore, doses, durations, and prior prescribing of other analgesics were investigated. RESULTS:Over the 5-year period, codeine prescribing decreased in children younger than 12 years (by 84% in France and Spain, 44% in GP practices in Germany, and 33% in the United Kingdom). The temporal pattern was compatible with the regulatory intervention in France and the United Kingdom, whereas a decrease throughout the study period was seen in Germany and Spain. Decreased prescribing associated with TA was suggested in ENT practices in Germany. CONCLUSIONS:Codeine prescribing for children decreased in line with introduced regulatory measures. Multidatabase studies assessing impact of measures by EU regulators are feasible.

Project description:IntroductionConcerns over serious respiratory depression in children led to two European Union (EU) referral procedures (in 2013 and 2015) to review the benefit-risk balance of codeine in this population when used for pain relief, cough or cold. Consequently, codeine should no longer be used in children aged < 12 years and restrictions were introduced for treatment in children ≥ 12 years.ObjectiveThis multinational collaborative study aimed to assess the effectiveness of these risk minimisation measures by evaluating changes in prescribing of codeine and alternative treatments.MethodChildren under 12 and 12-18 years old were followed between 2010 and 2017 to analyse quarterly trends in prescribing of codeine and alternative treatments in electronic health records from France, Germany, Norway, Spain and the United Kingdom using interrupted time series analysis.ResultsOverall prescribing of codeine in children decreased in all five countries, reaching near zero prevalence in children under 12 years of age. This was accompanied by an increase in use of other opioid analgesics in France (from 0.15 to 0.56 prevalence per 100 person-years immediately after the first referral), Norway (from 0.0006 to 0.0013 at the end of the study), the United Kingdom (from 0.018 to 0.05 at the end of the study), and an increase in non-opioid analgesics in Norway (from 0.045 to 0.075 at the end of the study) after the referral on pain relief indication. The referral on cough/cold indication led to a decrease in use of opioid and non-opioid antitussives in children aged < 12 years in France (from 10 to 7 and 20 to 16, respectively) and had no impact in other countries. Overall prescribing trends for codeine and alternatives were similar across both age groups within each country.ConclusionThe decrease in use of codeine shows that healthcare professionals followed the adopted measures and switched prescribing practices for pain management in children aged < 18 years towards opioid or non-opioid analgesics depending on national clinical and reimbursement settings. Whist the magnitude of the first referral on pain differed between countries, the second referral on cough/cold had only a minimal impact on the use of codeine and antitussives.

Project description:Children constitute 6-10% of all patients attending the emergency department (ED) by emergency medical services (EMS). However, discordant EMS use in children occurs in 37-61% with fever as an important risk factor. We aimed to describe EMS utilisation among febrile children attending European EDs. This study is part of an observational multicentre study assessing management and outcome in febrile children up to 18 years (MOFICHE) attending twelve EDs in eight European countries. Discordant EMS use was defined as the absence of markers of urgency including intermediate/high triage urgency, advanced diagnostics, treatment, and admission in children transferred by EMS. Multivariable logistic regression analyses were performed for the association between (1) EMS use and markers of urgency, and (2) patient characteristics and discordant EMS use after adjusting all analyses for the covariates age, gender, visiting hours, presenting symptoms, and ED setting. A total of 5464 (15%, range 0.1-42%) children attended the ED by EMS. Markers of urgency were more frequently present in the EMS group compared with the non-EMS group. Discordant EMS use occurred in 1601 children (29%, range 1-59%). Age and gender were not associated with discordant EMS use, whereas neurological symptoms were associated with less discordant EMS use (aOR 0.2, 95%CI 0.1-0.2), and attendance out of office hours was associated with more discordant EMS use (aOR 1.6, 95%CI 1.4-1.9). Settings with higher percentage of self-referrals to the ED had more discordant EMS use (p < 0.05). Conclusion: There is large practice variation in EMS use in febrile children attending European EDs. Markers of urgency were more frequently present in children in the EMS group. However, discordant EMS use occurred in 29%. Further research is needed on non-medical factors influencing discordant EMS use in febrile children across Europe, so that pre-emptive strategies can be implemented. What is Known: •Children constitute around 6-10% of all patients attending the emergency department by emergency medical services. •Discordant EMS use occurs in 37-61% of all children, with fever as most common presenting symptom for discordant EMS use in children. What is New: •There is large practice variation in EMS use among febrile children across Europe with discordance EMS use occurring in 29% (range 1-59%), which was associated with attendance during out of office hours and with settings with higher percentage of self-referrals to the ED. •Future research is needed focusing on non-medical factors (socioeconomic status, parental preferences and past experience, healthcare systems, referral pathways, out of hours services provision) that influence discordant EMS use in febrile children across Europe.

Project description:BackgroundThe epidemic of nonmedical use of prescription opioids has been fueled by the availability of legitimately prescribed unconsumed opioids. The aim of this study was to better understand the contribution of prescriptions written for pediatric patients to this problem by quantifying how much opioid is dispensed and consumed to manage pain after hospital discharge, and whether leftover opioid is appropriately disposed of. Our secondary aim was to explore the association of patient factors with opioid dispensing, consumption, and medication remaining on completion of therapy.MethodsUsing a scripted 10-minute interview, parents of 343 pediatric inpatients (98% postoperative) treated at a university children's hospital were questioned within 48 hours and 10 to 14 days after discharge to determine amount of opioid prescribed and consumed, duration of treatment, and disposition of unconsumed opioid. Multivariable linear regression was used to examine predictors of opioid prescribing, consumption, and doses remaining.ResultsMedian number of opioid doses dispensed was 43 (interquartile range, 30-85 doses), and median duration of therapy was 4 days (interquartile range, 1-8 days). Children who underwent orthopedic or Nuss surgery consumed 25.42 (95% confidence interval, 19.16-31.68) more doses than those who underwent other types of surgery (P < .001), and number of doses consumed was positively associated with higher discharge pain scores (P = .032). Overall, 58% (95% confidence interval, 54%-63%) of doses dispensed were not consumed, and the strongest predictor of number of doses remaining was doses dispensed (P < .001). Nineteen percent of families were informed how to dispose of leftover opioid, but only 4% (8 of 211) did so.ConclusionsPediatric providers frequently prescribed more opioid than needed to treat pain. This unconsumed opioid may contribute to the epidemic of nonmedical use of prescription opioids. Our findings underscore the need for further research to develop evidence-based opioid prescribing guidelines for physicians treating acute pain in children.
