Article Abstract
Objective: To describe challenges and solutions for calculating longitudinal daily opioid dose in morphine milligram equivalents from electronic health record prescriptions for a clinical trial of voluntary opioid reduction in patients with chronic non-cancer pain.
Materials And Methods: Researchers obtained opioid prescriptions for 525 participants from the National Patient-Centered Clinical Research Network datamart at three health systems. Daily opioid dose was calculated using dose conversions and summing across prescriptions after applying assumptions, reviewing suspect prescribing patterns, and removing spurious prescriptions.
Results: Out of 16 071 extracted prescriptions, 1207 (8%) were unusable, and 14 864 (92%) were analyzed.
Discussion: Numerous challenges were identified related to incomplete data, inaccurate refill dates, and overlapping or duplicate prescriptions.
Conclusion: Using electronic prescription data to calculate daily doses of opioid consumption is challenging and requires significant cleaning prior to use in research. This paper recommends steps to review and clean electronic opioid prescription data.

Department of Neurology, Gulhane Medical Faculty, University of Health Sciences, Ankara, Türkiye.
Introduction: Lambert-Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the neuromuscular junction, with limited large-scale epidemiological data. In this study, we aimed to determine the epidemiological profile of LEMS in Türkiye, and to assess associated malignancies, mortality, and prescription rates of pyridostigmine and amifampridine.
Methods: We identified LEMS cases through a retrospective review of clinical records for individuals with a G73.
Pharmacist Peer-Led Teaching Enhances Medical Undergraduate Prescribing: A Mixed-Methods Study.
Clin Teach

Warwick Medical School, Coventry, UK.
Background: Prescribing is a high-stakes clinical task where newly qualified doctors frequently report low confidence, with national data highlighting persistent error rates. Medical schools face logistical and staffing barriers in delivering high-quality, simulation-based prescribing education. Peer-led, interprofessional teaching, particularly by pharmacists, may offer a scalable solution in this context.

Aims: Our study described incidence and prevalence trends of type 1 diabetes in children and youth under 20 years of age from 1997 to 2023 in the Canadian province of British Columbia (BC) and assessed for a 4-, 5-, or 6-year cyclicity or increase in incidence during the COVID-19 pandemic.
Methods: Using linked population-level databases and a validated case-finding and diabetes differentiating algorithm, we identified children with type 1 diabetes diagnosed between 1997 and 2023. Data sources included hospital admissions, outpatient physician visits, and dispensed prescriptions.
