Effectiveness of Safety Warnings in Atypical Antipsychotic Drugs

Studies conducted to obtain drug authorization are often of short duration and based on small sample sizes in selected populations. Policies on drug safety rely on the validity of the methods used to achieve rapid and effective communication of new information. No formal evaluation has ever been made of the Spanish communications system, although indirect data have raised questions about its effectiveness.To evaluate the impact of two safety warnings issued by the Spanish Drug Agency, and of a later prior authorization requirement involving the use of atypical antipsychotic drugs in the elderly.The study was based on a time-series analysis constructed with data corresponding to monthly invo…

La prescripción farmacéutica en atención primaria. Informe SESPAS 2012

ResumenEn 2010, el Sistema Nacional de Salud (SNS) facturó 958 millones de recetas. Dada la masiva exposición de la población a los medicamentos, los riesgos asociados a su consumo adquieren una enorme relevancia desde la perspectiva de salud pública. Pacientes sobremedicados en situaciones de bajo riesgo e inframedicados en situaciones de indicación demostrada, deficientemente informados, polimedicados, automedicados y un porcentaje no despreciable que sufre efectos adversos evitables, es en buena parte la fotografía de la prescripción en atención primaria que puede mejorarse. Sorprendentemente, la mayor parte de las estrategias farmacéuticas en el SNS no se han orientado al control de est…

Burden of disease assessment with summary measures of population health for the Region of Valencia, Spain: a population-based study

Abstract Background and objective An important input to decision-making and health planning is a consistent and comparative description of the population health status. The purpose of this study was to describe the burden of disease in the Region of Valencia (Spain). Material and methods Disability-adjusted life years (DALYs) were calculated and divided into years of life lost (YLLs) and years lived with disability (YLDs). Using death registry data and Valencian population estimates in 2008, we calculated the number of deaths and YLLs. YLDs were based on age- and sex-specific data for countries of the EURO-A subregional level (which includes the Region of Valencia) from the Global Burden of…

Control of arterial hypertension in Spain

Hypertension is a leading global risk factor for the burden of cardiovascular disease. Data about changes in hypertension control are important to set intervention priorities. We conducted a systematic review and meta-analysis of epidemiological studies to determine the control of hypertension in Spain over the past decade.A search of PubMed/MEDLINE, SCOPUS and IME was performed for epidemiological studies conducted in Spain (since 2000) with data on control rates for hypertension. The primary outcome was the prevalence of uncontrolled hypertension defined as the percentage of patients having SBP at least 140 mmHg and/or DBP at least 90 mmHg. For populations at risk (e.g. patients with diab…

Association of Vitamin K and Non-Vitamin K Oral Anticoagulant Use and Cancer Incidence in Atrial Fibrillation Patients

The association between the use of vitamin K antagonists (VKAs) and cancer risk reduction remains unclear. We aimed to assess the association between the use of VKAs or direct oral anticoagulants (DOACs) and the incidence of cancer in a large cohort of patients with atrial fibrillation (AF) by means of a population-based, propensity-weighted cohort study using population-wide databases including patients diagnosed with nonvalvular AF (NVAF) followed for up of 5 years (median 2.94 years). We created two cohorts based on the initiation therapy (VKA or DOAC). Initiation with VKA or DOAC was defined as filling a prescription with no previous exposure in the preceding 12 months. Cancer diagnoses…
