Due to the heterogeneity of existing European sources of observational healthcare data, data source-tailored choices are needed to execute multi-data source, multi-national epidemiological studies. This makes transparent documentation paramount. Inthis proof-of-concept study, a novel standard data derivation procedure was tested in a set of heterogeneous data sources
OBJECTIVE: To determine the incidence of chronic comorbidities among children with type 1 diabetes (T1D) and to compare incidences with a group of children without diabetes. DESIGN: Population-based cohort study. SETTING: Dutch PHARMO database (199-2010). PATIENTS: All patients (<19 years old) with T1D between 1999 and 2009 (T1D cohort) and a group of age- and sex-matched (ratio: 1-4) children without diabetes (reference cohort)
AIM: The aim of the study was to document long term trends in oral antidiabetic drug (OAD) use among children and adolescents in the Netherlands. METHODS: A population-based cohort study was conducted using the Dutch PHARMO Database Network. All paients younger than 20 years old with at least one OAD dispensing were identified
BACKGROUND: Metformin, statin and aspirin use seem associated with decreased mortality in cancer patients, though, without adjusting for one another. Independent associations of these drugs with overall mortality after colorectal cancer (CRC) diagnsis within glucose-lowering drugs (GLDs) users were assessed
AIMS/HYPOTHESIS: Adherence to glucose-lowering drug (GLD) treatment regimens is crucial for metabolic control and improving prognosis. Because a diagnosis of cancer might have an impact on adherence to medication, this study explored changes in adhrence to GLDs following a cancer diagnosis. METHODS: All new users of GLDs between 1998 and 2011 who lived in the Eindhoven Cancer Registry-PHARMO Database Network catchment area were selected
AIMS: Intensive glucose control, often involving insulin treatment, failed to improve cardiovascular outcomes in several clinical trials. Observational studies reported an association between insulin use and cardiovascular disease (CVD) risk. It hatherefore been suggested that insulin adversely affects CVD risk
A population-based cohort study was conducted in the Dutch PHARMO database to investigate prevalence and patterns of anti-infective medication use in children and adolescents with type 1 diabetes (T1D) before and after the onset of this disease. Alpatients <19 years with at least 2 insulin prescriptions (1999 to 2009) were identified (T1D cohort) and compared with an age- and sex-matched (ratio: 1 up to 4) diabetes-free reference group
BACKGROUND: There is a highly variable asymptomatic period of beta cell destruction prior to the clinical presentation of type1 diabetes. It is not well known what triggers type 1 diabetes to become a clinically overt disease. This explorative studaimed to identify the association between disease history/medication use and the clinical manifestation of type 1 diabetes
Background: The use of thiazolidinediones (TZDs) has been associated with increased fracture risks. Our aim was to estimate the risk of fracture with TZDs in three different healthcare registries, using exactly the same study design, and to performan individual patient data meta-analysis of these three studies
BACKGROUND: Relevant safety signals in the EU are regularly communicated in so-called ‘Direct Healthcare Professional Communications’ (DHPCs) or European Medicines Agency (EMA) press releases. Trends of a decrease in the use of rosiglitazone followng regulatory safety warnings have been described in the US
