Adverse drug reactions and nonadherence to treatment are important causes of morbidity and cost to the health service. Much of this resource is spent to treat preventable cases of DRM, which represents a great waste of resources.
ObjectiveTo characterise the prescription of non-formulary drugs to children and neonates at a Brazilian teaching hospital and identify adverse drug reactions (ADRs), drug interactions, and prescription of potentially hazardous medicines.MethodsA prospective exploratory study was carried out between January and May 2011 at the general paediatric wards and paediatric oncology, paediatric intensive care, and neonatal care units of the study hospital. Non-formulary drugs were categorised as approved, off-label, or not approved for use in children according to Brazilian compendia. Electronic health records were actively searched for ADRs and the possibility of moderate to severe interactions between non-formulary drugs and other medicines was determined with the Micromedex® database.ResultsOverall, 109 children or neonates received non-formulary drugs. Of these drugs, 54% were approved for use in children, 12.2% were used off-label, and 33.8% were not approved for use in children. Non-formulary drugs accounted for 13.4% of total prescriptions; 5.3% of drugs had a potential for interactions and five were possibly associated with ADRs.ConclusionsPrescription of non-formulary drugs not approved for use in children was common at the study hospital. Studies such as this provide information on the use of medicines for special indications and permit assessment of the relevance of hospital formularies for the paediatric population.
This article aims to investigate the morbidities related to medications, their risk factors and causes detected in patients who seek the Hospital Emergency Service of a University in the South of Brazil. Data collection was based on application of a questionnaire to patients of a minimum age of 18 years, that signing the Term of Free and Informed Consent (TFIC), during the period from October 2013 to March 2014, and analysis of electronic record charts. Cases were evaluated by pharmacists and a doctor to define whether it was a case of medication related morbidity (MRM) and to establish its possible causes. Avoidability of MRM was verified based on criteria previously established in the literature. In total 535 patients were interviewed, and the frequency of MRM was 14.6%, Approximately 45% of MRMs were related to safety in the use of medications, and approximately 50% presented user-related questions as the possible cause. Hospitalization was required in 44.8% of MRM cases; 62.7% of cases were considered avoidable. Presence of chronic disease and use of potentially dangerous medication and low therapeutic index were considered independent factors associated with development of MRM, according to statistical analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
