Multi-country study

Antibiotic use varies substantially among adults: a cross-national study from five European Countries in the ARITMO project

PURPOSE: To examine patterns of outpatient and community antibiotic use among adults in five European countries. METHODS: We used healthcare data of 28.8 million adults from six population-based ARITMO project databases to ascertain information onystemic antibiotic use in Denmark (2000-2008), the Netherlands (1999-2010), Italy (2000-2010), the UK (1996-2009), and Germany (2004-2008)

Evaluating performance of electronic healthcare records and spontaneous reporting data in drug safety signal detection

Background Electronic reporting and processing of suspected adverse drug reactions (ADRs) is increasing and has facilitated automated screening procedures. It is crucial for healthcare professionals to understand the nature and proper use of data aailable in pharmacovigilance practice. Objectives To (a) compare performance of EU-ADR [electronic healthcare record (EHR) exemplar] and FAERS [spontaneous reporting system (SRS) exemplar] databases in detecting signals using “positive” and “negative” drug-event reference sets; and (b) evaluate the impact of timing bias on sensitivity thresholds by comparing all data to data restricted to the time before a warning/regulatory action

Risk of upper gastrointestinal bleeding from different drug combinations

BACKGROUND & AIMS: Concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) and low-dose aspirin increases the risk of upper gastrointestinal bleeding (UGIB). Guidelines suggest avoiding certain drug combinations, yet little is known abouthe magnitude of their interactions. We estimated the risk of UGIB during concomitant use of nonselective (ns)NSAIDs, cyclooxygenase -2 selective inhibitors (COX-2 inhibitors), and low-dose aspirin with other drugs

Signal detection of potentially drug-induced acute liver injury in children using a multi-country healthcare database network

BACKGROUND: Data mining in spontaneous reporting databases has shown that drug-induced liver injury is infrequently reported in children. OBJECTIVES: Our objectives were to (i) identify drugs potentially associated with acute liver injury (ALI) inhildren and adolescents using electronic healthcare record (EHR) data; and (ii) to evaluate the significance and novelty of these associations

Replication of the OMOP Experiment in Europe: Evaluating Methods for Risk Identification in Electronic Health Record Databases

BACKGROUND: The Observational Medical Outcomes Partnership (OMOP) has just completed a large scale empirical evaluation of statistical methods and analysis choices for risks identification in longitudinal observational healthcare data. This experimnt drew data from four large US health insurance claims databases and one US electronic health record (EHR) database, but it is unclear to what extend the findings of this study apply to other data sources

Drug-induced acute myocardial infarction: identifying ‘prime suspects’ from electronic healthcare records-based surveillance system

BACKGROUND: Drug-related adverse events remain an important cause of morbidity and mortality and impose huge burden on healthcare costs. Routinely collected electronic healthcare data give a good snapshot of how drugs are being used in ‘real-world’settings. OBJECTIVE: To describe a strategy that identifies potentially drug-induced acute myocardial infarction (AMI) from a large international healthcare data network

Harmonization process for the identification of medical events in eight European healthcare databases: the experience from the EU-ADR project

OBJECTIVE: Data from electronic healthcare records (EHR) can be used to monitor drug safety, but in order to compare and pool data from different EHR databases, the extraction of potential adverse events must be harmonized. In this paper, we descrie the procedure used for harmonizing the extraction from eight European EHR databases of five events of interest deemed to be important in pharmacovigilance: acute myocardial infarction (AMI); acute renal failure (ARF); anaphylactic shock (AS); bullous eruption (BE); and rhabdomyolysis (RHABD)
