Anaphylaxis is a potentially fatal systemic adverse drug reaction (ADR). It is an unpredictable and mostly dose-independent event that occurs suddenly following exposure to the causative drug. Our objective was to characterize a case series of anaphylactic reactions reported to the Portuguese Pharmacovigilance authority during the past decade. Patients’(More)
BACKGROUND Spontaneous adverse drug reaction (ADR) reporting has been described as an efficient method to detect drug safety signals. However, under-reporting is a major issue undermining the effectiveness of spontaneous reports. Among hospitalized patients, ADRs are a particularly serious problem because these patients are often treated with more than one(More)
BACKGROUND Spontaneous reporting of adverse drug reactions (ADRs) is the method most widely used by pharmacovigilance systems, with the principal limitation being the physician's underreporting. OBJECTIVE This study sought to evaluate the results of workshop and telephone-interview interventions designed to improve the quantity and relevance of ADR(More)
OBJECTIVE Reporting of adverse drug reactions (ADRs) may differ between countries. METHODS In a retrospective descriptive study we analysed the potential causative drugs and clinical situations related to spontaneously reported ADRs over 10 years to a regional pharmacovigilance centre in Portugal. KEY FINDINGS We collected 3165 cases (36% of all(More)
OBJECTIVE To evaluate the results of an intervention to improve the number and relevance of reports of adverse drug reactions. METHODS A cluster-randomized controlled trial was conducted with pharmacists working in Northern Portugal, in 2007. After randomization, 364 individuals were placed into the intervention group (261 in telephone interviews and 103(More)
In Portugal, the National Pharmacovigilance System (NPS) was created in 1992, completing during this year 20 years of existence. Having been established in a centralized manner, it soon became aware that its geographic decentralization would bring advantages in terms of proximity of the System to health professionals as well as the involvement of the(More)
BACKGROUND Adverse drug reactions (ADRs) are a well-recognized public health problem and a major cause of death and hospitalization in developed countries. The safety of a new drug cannot be established until it has been on the market for several years. Keeping drug reactions under surveillance through pharmacovigilance systems is indispensable. However,(More)
OBJECTIVE Adverse drug reactions (ADR) are a public health problem. They cause significant morbidity, mortality and health costs. Less is known about pediatric ADR. Our goal was to characterize a pediatric case series of ADR reported to the Portuguese Pharmacovigilance System (PPS) during the past 10 years. RESEARCH DESIGN AND METHODS Retrospective(More)
OBJECTIVE To describe different approaches to promote adverse drug reaction reporting among health care professionals, determining their cost-effectiveness. METHODS We analyzed and compared several approaches taken by the Northern Pharmacovigilance Centre (Portugal) to promote adverse drug reaction reporting. Approaches were compared regarding the number(More)
