However, an increase in off-label TRT supplementation is occurring in men despite lack of efficacy and safety data. Furthermore, the associations between TRT and comorbid diseases such as cardiovascular disease, diabetes and prostate cancer (CaP), have not been well characterized in this population. METHODS All prescriptions for TRT between 1997 and 2013 were identified from the longitudinal British Columbian (pharmacy) PharmaNet database. Descriptive statistics were used to examine demographic and utilization information of men with TRT prescriptions using the longitudinal inpatient (discharge abstract database) DAD and outpatient (medical services plan) MSP databases. This was completed in accordance with UBC ethics protocols. RESULTS 40,878 patients prescribed TRT within the study period of 16 years were evaluated. The majority of TRT were prescribed by general practitioners (92.0%) with few prescriptions by urologists (7.6%), internists (4.7%) and endocrinologists (4.1%),. The number of prescriptions per year increased 7-fold over the 16-year period, specifically in men aged 51-61 (from 2,205 to 16,066) and 61-71 (from 2,025 to 14,541). 74% of men received more than one TRT prescription and most (76%) changed the route of TRT administration over the course of their treatment. Injections were the most common route of administration, followed by capsules, then gels. The mean duration of TRT use was 518 days (SD +/- 821 days). Men prescribed TRTs had a baseline prevalence of CaP in 1.1%, diabetes in 36.9%, myocardial infarctions in 9.9%, and arterial embolism or thrombosis in 0.2% of men. CONCLUSIONS We have characterized the longitudinal TRT patterns in a population of 40,878 TRT users. Despite the lack of efficacy and safety data there were annual increases in the prescription numbers. The most popular route of administration was injections. TRT use occurred in many men with baseline cardiovascular disease and CaP. Future work will aim to investigate TRT use in relation to pre, intra, and post-treatment serum TRT levels, cardiovascular events, diabetes and prostate diagnoses. © 2016FiguresReferencesRelatedDetails Volume 195Issue 4SApril 2016Page: e504 Advertisement Copyright & Permissions© 2016MetricsAuthor Information Jennifer Locke More articles by this author Ryan Flannigan More articles by this author Hao Luo More articles by this author Mahyar Etminan More articles by this author Ted Hoyda More articles by this author S.
