  • Changes in glucose-lowering drug use before and after cancer diagnosis in patients with diabetes.Abstract

    AIM: This study explores the changes in glucose-lowering drug (GLD) use before and after cancer diagnosis among patients with diabetes. METHODS: New GLD users (1998-2011) living in the Dutch ECR-PHARMO catchment area were selected from the PHARMO Dtabase Network (n=52,228). Those with a primary cancer diagnosis were considered cases (n=3281) and matched with eligible controls (n=12,891) without cancer during follow-up

  • Factors Associated with Type 2 Diabetes Mellitus Treatment Choice Across Four European Countries.Abstract

    PURPOSE: The aim of this analysis was to identify factors associated with the choice of type 2 diabetes mellitus (T2DM) therapy at the time of intensification of antidiabetic treatment across 4 European countries. METHODS: Antidiabetic drug prescrition/dispensing records and patients’ characteristics were obtained from the electronic health care records of patients with T2DM from the Netherlands (NL), Italy, and Spain (ES) (all, 2007-2011); and the United Kingdom (UK; 2008-2012)

  • Thrombotic risk minimization for Diane-35 and generics.Abstract

    BACKGROUND: This study aimed to evaluate the effect of risk minimization measures on cyproterone acetate/ethinylestradiol (CPA/EE) use in the Netherlands. Potential indications of use and concomitant pharmacy dispensing of other hormonal contraceptves (HC) were assessed among new users in 2011, 2012, and 2014

  • Decrease in Switches to ‘Unsafe’ Proton Pump Inhibitors After Communications About Interactions with Clopidogrel.Abstract

    BACKGROUND: In 2009 and 2010 medicines regulatory agencies published official safety statements regarding the concomitant use of proton pump inhibitors and clopidogrel. We wanted to investigate a change in prescription behaviour in prevalent gastrorotective drug users (2008-2011). METHODS: Data on drug use were retrieved from the Out-patient Pharmacy Database of the PHARMO Database Network

  • Psychiatric medication use before and after the onset of type 1 diabetes in children and adolescents: A population-based cohort study.Abstract

    BACKGROUND: Several studies showed a bidirectional association between type 2 diabetes and psychiatric disorders in adults. Because there is limited information on the association between type 1 diabetes (T1D) and psychiatric disorders (including pychiatric medication use) in children and adolescents, we assessed frequency of use of these medications before and after the onset of T1D

  • Type 2 Diabetes Mellitus Treatment Patterns Across Europe: A Population-Based Multi-Database Study.Abstract

    PURPOSE: The aim of this study was to determine the similarities and differences of type 2 diabetes mellitus (T2DM) treatment patterns in daily practice in 5 European countries and whether these reflect differences in guidelines. METHODS: Prescriptons for drugs used in diabetes treatment during a 5-year study period were obtained from electronic databases

  • Use of Lipid-Modifying Therapy and LDL-C Goal Attainment in a High-Cardiovascular-Risk Population in the Netherlands.Abstract

    PURPOSE: This study investigates lipid-modifying therapy (LMT) and LDL-C goal attainment in a real-world, high-cardiovascular-risk population in the Netherlands. METHODS: From the PHARMO Database Network, patients aged >/=18 years with an LDL-C meaurement in 2012 (index date) were selected and hierarchically classified into the following mutually exclusive high-cardiovascular-risk categories: familial hypercholesterolemia (FH), recent acute coronary syndrome (ACS), coronary heart disease, ischemicstroke, peripheral arterial disease, and diabetes mellitus
