PURPOSE: Mortality data within the Sentinel Death Tables remain generally uncharacterized. Assessment of mortality data within Sentinel will help inform its utility for medical product safety studies. METHODS: To determine if Sentinel contains sufficient all-cause and cause-specific mortality events to power postmarketing safety studies. We calculated crude rates of all-cause mortality and suicide and proportional mortality from suicide from 2004 to 2012 in seven Sentinel data partners...

PURPOSE: Oral use is the primary route of administration among non-medical prescription opioid users. While progression to non-oral routes and shifts to stronger opioids have been previously studied as ways to cope with tolerance, the prevalence and patterns of those who cope by increasing the number of pills/tablets ingested at one time (ie, multi-pill use) has not been assessed. METHODS: A subset (N = 231) of treatment-seeking opioid users from a national opioid surveillance system, participating in the Researchers and Participants Interacting Directly (RAPID) Program, completed an online survey centered on multi-pill use...

PURPOSE: Claims databases offer large populations for research, but lack clinical details. We aimed to develop predictive models to identify estrogen receptor positive (ER+) and human epidermal growth factor negative (HER2-) early breast cancer (ESBC) and advanced stage breast cancer (ASBC) in a claims database. METHODS: Female breast cancer cases in Anthem's Cancer Care Quality Program served as the gold standard validation sample. Predictive models were developed from clinical knowledge and empirically from claims data using logistic and lasso regression...

PURPOSE: Heart failure (HF) is a common, serious, and still poorly known illness, which might benefit from studies in claims databases. However, to provide reliable estimates, HF patients must be adequately identified. This validation study aimed to estimate the diagnostic accuracy of the International Classification of Diseases, Tenth Revision (ICD-10) codes I50.x, heart failure, in the French hospital discharge diagnoses database. METHODS: This study was performed in two university hospitals, comparing recorded discharge diagnoses and electronic health records (EHRs)...

PURPOSE: Fentanyl transdermal system (FTS) is intended only for patients with prior opioid tolerance. The purpose of this study is to identify the proportion of new FTS users who had evidence of prior opioid tolerance, by dosage strength, in FDA's Sentinel System. METHODS: We identified new FTS episodes (183-day washout) from 2009 through 2013. Members were <65 years and enrolled in medical and pharmacy coverage for 183 days prior to initial FTS dispensing (index)...

PURPOSE: Comparative outcomes of treatment with antiplatelet drugs in patients with acute coronary syndrome (ACS) and co-morbid diabetes mellitus (DM) are not well studied. METHODS: We performed a cohort study using US commercial claims data (2009-2015) and conducted the following pairwise comparisons in ACS patients with DM: prasugrel vs clopidogrel, ticagrelor vs clopidogrel, and prasugrel vs ticagrelor. Outcomes of interest included (1) a composite effectiveness endpoint including myocardial infarction, ischemic stroke, or inpatient mortality; (2) a composite safety endpoint including major bleeding events requiring hospitalization; and (3) pneumonia hospitalizations as a negative control endpoint...

PURPOSE: To describe how often patients with depression initiating antidepressants receive their depression diagnosis and prescriptions from the same provider and, when simultaneously initiating benzodiazepines, how often both prescriptions come from the same provider. METHODS: Using a US healthcare claims database, we created a cohort of adults (18-64 years) with a depression diagnosis who initiated antidepressants. We examined concordance by provider specialty and provider identifier between (a) the first antidepressant prescription fill and most proximal depression diagnosis, and (b) the initial antidepressant and benzodiazepine prescription fills among simultaneous benzodiazepine and antidepressant initiators...

PURPOSE: In 2012, the Committee for Medicinal Products for Human Use (CHMP) restricted prescription of trimetazidine (TMZ) to "add-on therapy for patients with stable angina pectoris who are inadequately controlled by or intolerant to first-line therapies." TMZ was no longer indicated for ophthalmology and otolaryngology. Risk minimization measure (RMM) was communicated to physicians. The survey presented here evaluated effectiveness of the RMM and assessed physicians knowledge and compliance with RMM...

PURPOSE: Many outcomes derived from electronic health records (EHR) not only are imperfect but also may suffer from exposure-dependent differential misclassification due to variability in the quality and availability of EHR data across exposure groups. The objective of this study was to quantify the inflation of type I error rates that can result from differential outcome misclassification. METHODS: We used data on gold-standard and EHR-derived second breast cancers in a cohort of women with a prior breast cancer diagnosis from 1993 to 2006 enrolled in Kaiser Permanente Washington...

PURPOSE: The purpose of the study is to determine whether initiatives to improve the safety of opioid prescribing decreased injuries in people using chronic opioid therapy (COT). METHODS: We conducted an interrupted time series analysis using data from Group Health (GH), an integrated health care delivery system in the United States. In 2007, GH implemented initiatives which substantially reduced daily opioid dose and increased patient monitoring. Among GH members age 18 or older receiving COT between 2006 and 2014, we compared injury rates for patients in GH's integrated group practice (IGP; exposed to the initiatives) vs patients cared for by contracted providers (not exposed)...

PURPOSE: Data mining has been introduced as one of the most useful methods for signal detection by spontaneous reports, but data mining is not always effective in detecting all safety issues. To investigate appropriate situations in which data mining is effective in routine signal detection activities, we analyzed the characteristics of signals that the US Food and Drug Administration (FDA) identified from the FDA Adverse Event Reporting System (FAERS). METHODS: Among the signals that the FDA identified from the FAERS between 2008 1Q and 2014 4Q, we selected 233 signals to evaluate in this study...

PURPOSE: Accurate capture of medication use is important for high quality research. For epidemiologic studies, medication histories are the most common measure of exposure when trying to identify associations between medications and outcomes. Concomitant medications can alter the efficacy or safety of study drugs in clinical trials. However, there are few studies evaluating the accuracy and efficiency of methods to collect these histories. The objective of this study is to compare the accuracy of medication histories collected by structured interview to histories captured using a tablet-based application...
