Eventos adversos em serviços de urgência e emergência: uma revisão integrativa de literatura / Adverse effects in urgency and emergency services: an integrative literature review / Eventos adversos en servicios de urgencias y emergencia: una revisión integradora de la literatura

O artigo tem o objetivo de analisar a produção científica disponível na literatura sobre os eventos adversos em serviços de urgência e emergência. Assim, realizou-se uma revisão integrativa por meio de levantamento bibliográfico em agosto de 2022, com busca nas seguintes bases de dados eletrônicas: Índice Bibliográfico Español en Ciencias de la Salud (Ibecs), Base de Dados em Enfermagem (BDENF) via Biblioteca Virtual da Saúde (BVS), Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), Medical Literature Analysis and Retrieval System Online (Medline) via PubMed e Web of Science via Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes). A busca resultou na amostra final de dez artigos, que foram descritos com base em quatro eixos temáticos, conforme tipo de serviço e desenvolvimento do estudo. Os assuntos mais abordados nas produções foram: terapia medicamentosa, incidentes relacionados à organização do serviço, falhas nas prescrições, prescrições verbais, incidentes com previsão e provisão de materiais e abastecimento. A análise das produções expõe o maior número de artigos da Espanha, do Brasil e dos Estados Unidos, com ênfase nos assuntos relacionados a eventos adversos em ambientes de urgência e emergência intra-hospitalares, demonstrando que as pesquisas sobre segurança do paciente em serviços de urgência e emergência são incipientes, assim como são escassos os estudos no Brasil voltados para as unidades de pronto atendimento.

The article aims to analyze the scientific production available in the literature on adverse events in urgency and emergency services. Thus, an integrative review was carried out with a bibliographic survey, in August 2022, with a search in the electronical databases: Spanish Bibliographic Index in Health Sciences (IBECS), Database in Nursing (BDENF) via Virtual Health Library (BVS), Latin American and Caribbean Literature in Health Sciences (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE) via PubMed and Web of Science via Portal de Periódicos da Coordination for the Improvement of Higher Education (CAPES). The search resulted in a final sample of ten articles, which were described based on four thematic axes, in accordance with the type of study development and service. The subjects most discussed in the productions were: drug therapy, incidents related to the organization of the service, failures in prescriptions, verbal prescriptions, incidents with prediction, and provision of materials and supplies. The analysis of the productions exposes the larger number of articles from Spain, Brazil, and the United States, with emphasis on subjects related to adverse events in in-hospital urgent and emergency environments, demonstrating that research on patient safety in urgency and emergency services are incipient, as well the few studies in Brazil directed to emergency care units.

Assessment and comparison of anticholinergic exposure in older adults at a Basic Health Unit in Porto Alegre / Avaliação e comparação da exposição anticolinérgica em idosos de uma Unidade Básica de Saúde de Porto Alegre

Objectives: To estimate the anticholinergic burden in geriatric patients using two scales and to assess the degree of agreement between them. Methods: Data from an observational study conducted in a primary health care service were used. Anticholinergic burden was assessed using the Belgian Scale Muscarinic Acetylcholinergic Receptor ANTagonist Exposure Scale and the Brazilian Scale of Medicines with Anticholinergic Activity. The cumulative anticholinergic burden score was classified using a categorical approach: Brazilian scale (0: none; 1 ­ 2: low; ≥ 3: high) and Belgian scale (0: none; 0.5 ­ 1.5: low; ≥ 2: high). The degree of agreement between the two instruments was obtained through Cohen's kappa coefficient. Results: A total of 374 older people were included, most of them female and aged between 60 and 69 years. At least one potentially inappropriate drug with anticholinergic activity was used by 60.70% of patients according to the Brazilian scale and 32.89% by the Belgian scale. On average, 20.85% were under high anticholinergic exposure. Overall, on both scales, the most commonly recurrent medications were those indicated for the treatment of psychiatric disorders. Agreement between the scales was moderate (Kappa = 0.43). Conclusions: A high percentage of older adults was exposed to drugs with an anticholinergic burden, posing risks to health and quality of life. Consensus is needed on how anticholinergic burden is calculated by these scores, as well as standardization of the list of included drugs.

Objetivos: Estimar a carga anticolinérgica em idosos com base em duas escalas e avaliar o grau de concordância entre estas. Metodologia: Foram utilizados dados de um estudo observacional realizado em um serviço de atenção primária. A carga anticolinérgica foi avaliada pela escala belga Muscarinic Acetylcholinergic Receptor ANTagonist Exposure Scale e da Escala Brasileira de Medicamentos com Atividade Anticolinérgica. A pontuação da carga anticolinérgica cumulativa foi classificada utilizando uma abordagem categórica: escala brasileira (0: nenhuma, 1 ­ 2: baixa, ≥ 3: alta) e escala belga (0: nenhuma, 0,5 ­ 1,5: baixa, ≥ 2: alta). O grau de concordância entre as duas ferramentas foi obtido por meio do coeficiente Capa de Cohen. Resultados: Foram incluídos 374 idosos, a maioria do sexo feminino e com idade entre 60 a 69 anos. O uso de pelo menos um medicamento potencialmente inapropriado com atividade anticolinérgica foi verificado em 60,70% dos idosos com a aplicação da escala brasileira e em 32,89% com a escala belga. Em média, 20.85% estavam sob alta exposição anticolinérgica. De modo geral, os medicamentos mais recorrentes, para ambas as escalas, foram os indicados para o tratamento de transtornos psiquiátricos. A concordância entre as escalas foi moderada (Capa = 0,43). Conclusão: Um percentual elevado de idosos estava exposto a medicamentos com carga anticolinérgica, representando riscos para a saúde e a qualidade de vida. É necessário um consenso sobre como calcular a carga anticolinérgica nos diferentes escores, bem como a padronização da lista de medicamentos incluídos.

Uso ambulatorio de medicamentos potencialmente inapropiados en adultos mayores usuarios de la RAP Metropolitana de ASSE durante 2019 / Potentially inappropriate medication use in older adults assisted as outpatients in ASSE's Metropolitan RAP (Primary Health Care) during 2019 / Uso ambulatorial de medicamentos potencialmente inapropriados em idosos usuários da RAPE Metropolitana da ASSE durante 2019

Introducción: los adultos mayores son una población de riesgo para el desarrollo de reacciones adversas a los medicamentos. Los medicamentos potencialmente inapropiados son aquellos que representan mayores riesgos que beneficios en este grupo etario. Se cuenta con herramientas de apoyo a la prescripción en geriatría que permiten identificar a estos medicamentos y mediante la aplicación de estudios de utilización de medicamentos, podemos describir o analizar el uso de los mismos en una población. Objetivos: reconocer disponibilidad de medicamentos potencialmente inapropiados para adultos mayores en la RAP metropolitana de ASSE durante 2019 y establecer un diagnóstico de situación de consumo de los mismos durante ese año. Método: se realizó un análisis del vademécum institucional mediante la aplicación de los Criterios de Beers 2019 y dos escalas de riesgo anticolinérgico para identificar medicamentos potencialmente inapropiados. Posteriormente se realizó un estudio de utilización de los medicamentos identificados, mediante datos de dispensación de farmacia entre el 1 de enero y 31 de diciembre de 2019. El consumo se expresó en Dosis Diarias Definidas por cada 1000 adultos mayores-año (DHD). Resultados: se identificaron 16 medicamentos potencialmente inapropiados, de los cuales los más usados fueron clonazepam (DHD 69), quetiapina (65,6), alprazolam (DHD 43,7), flunitrazepam (DHD 42,7) y zolpidem (DHD 36,4). Conclusiones: la aplicación de herramientas explícitas facilita la identificación de medicamentos potencialmente inapropiados para adultos mayores y se evidenció un consumo elevado de los mismos durante el año 2019 a expensas de derivados benzodiazepínicos y quetiapina.

Introduction: older adults are at higher risk for developing adverse drug reactions. Potentially inappropriate medications are drugs that have more risks than benefits in this age group. There are a number of tools to support the prescription of medication in geriatrics that allow the identification of these medications, and by applying studies developed on the use of medications we may describe or analyze their impact on a given population. Objectives: to recognize availability of potentially inappropriate medications in older adults in ASSE's Metropolitan RAP during 2019 and to draw conclusions about the current situation in terms of the consumption of this kind of medications. Method: an institutional analysis of medications available in each healthcare provided was conducted through the application of Beers Criteria 2019, and two anticholinergic risk scales were used to identify potentially inappropriate medications. Subsequently, the use of the medications identified was studied by applying pharmacy dispensing data between January 1 and December 31, 2019. Consumption was expressed in defined daily doses every 1000 adults per year (DHD). Results: 16 potentially inappropriate medications were identified, the most widely used of which were clonazepam (DHD 69), quetiapine (65.6), alprazolam (DHD 43.7), flunitrazepam (DHD 42.7) and zolpidem (DHD 36.4). Conclusions: Applying explicit tools makes it easier to identify potentially inappropriate medications for older adults. An increased consumption of these kinds of drugs was noticed during 2019, as a result of benzodiazepine derivatives and quetiapine.

Introdução: os idosos são uma população de risco para o desenvolvimento de reações adversas a medicamentos. Medicamentos potencialmente inapropriados são aqueles que apresentam maiores riscos do que benefícios nessa faixa etária. Existem ferramentas de apoio à prescrição em geriatria que permitem identificar esses medicamentos e, por meio da aplicação de estudos de utilização de medicamentos, descrever ou analisar seu uso em uma população. Objetivos: reconhecer a disponibilidade de medicamentos potencialmente inapropriados para idosos na RAP metropolitana da ASSE durante o ano de 2019 e estabelecer um diagnóstico de consumo durante esse ano. Método: o formulário institucional foi analisado utilizando os Critérios de Beers 2019 e duas escalas de risco anticolinérgico para identificar medicamentos potencialmente inapropriados. Posteriormente, foi realizado um estudo de consumo dos medicamentos identificados, através dos dados de dispensação da farmácia entre 1 de janeiro e 31 de dezembro de 2019. O consumo foi expresso em Doses Diárias Definidas por 1000 idosos-ano (DHD). Resultados: foram identificados 16 medicamentos potencialmente inapropriados, sendo clonazepam (DHD 69), quetiapina (65,6), alprazolam (DHD 43,7), flunitrazepam (DHD 42,7) e zolpidem (DHD 36,4) os mais utilizados Conclusões: a aplicação de ferramentas explícitas facilita a identificação de medicamentos potencialmente inapropriados para idosos; foi observado um alto consumo dos mesmos em detrimento dos derivados benzodiazepínicos e da quetiapina durante o período do estudo.

Indicación y prescripción de macrólidos en una población colombiana / Study of the indications for macrolide prescriptions in a Colombian population

Introducción. El uso inadecuado de antibióticos se asocia con aumento de la resistencia antimicrobiana, mayores costos de atención médica, más efectos adversos y peores resultados clínicos. Objetivo. Determinar los patrones de prescripción y las indicaciones aprobadas y no aprobadas para macrólidos en un grupo de pacientes en Colombia. Materiales y métodos. Se hizo un estudio de corte transversal sobre las indicaciones de uso de macrólidos en pacientes ambulatorios a partir de una base de datos de dispensación de medicamentos de 8,5 millones, aproximadamente, de personas afiliadas al sistema de salud de Colombia. Se consideraron variables sociodemográficas, farmacológicas y clínicas. Resultados. Se encontraron 9.344 pacientes que habían recibido prescripción de macrólidos; su mediana de edad era de 40,1 años (rango intercuartílico: 27,1-53,3 años) y el 58,3 % correspondía a mujeres. El macrólido más prescrito fue la azitromicina (38,8 %) y los usos más frecuentes fueron el tratamiento de la infección por Helicobacter pylori (15,9 %) y la neumonía (15,8 %). El 31,3 % de las prescripciones correspondía a indicaciones no aprobadas, destacándose el resfriado común (7,8 %), la Covid-19 (4,0 %) y la bronquitis aguda (3,5 %). La residencia en la región Caribe (OR=1,17; IC95% 1,05-1,31), las prescripciones odontológicas (OR=2,75; IC95% 1,91-3,96), las comorbilidades respiratorias crónicas (OR=1,30; IC95% 1,08-1,56), y la prescripción de eritromicina (OR=3,66; IC95% 3,24-4,14) o azitromicina (OR=2,15; IC95% 1,92 2,41), se asociaron con una mayor probabilidad de recibir macrólidos para indicaciones no aprobadas, en tanto que tener entre 18 y 64 años (OR=0,81; IC95% 0,71-0,93), 65 o más años (OR=0,77; IC95% 0,63-0,94) y residir en Bogotá-Cundinamarca (OR=0,74; IC95% 0,65 0,85) reducían dicho riesgo. Conclusiones. La mayoría de los pacientes recibieron macrólidos para infecciones del sistema respiratorio; la eritromicina y la azitromicina se prescribieron en indicaciones no aprobadas en menores de 18 años y en quienes presentaban enfermedades respiratorias crónicas.

Introduction: The inappropriate use of antibiotics is associated with a greater risk for antimicrobial resistance, high health care costs, adverse events, and worse clinical outcomes. Objective: To determine the prescription patterns and approved and nonapproved indications for macrolides in a group of patients from Colombia. Materials and methods: This was a cross-sectional study on the indications for the use of macrolides in outpatients registered in a drug-dispensing database of approximately 8.5 million people affiliated with the Colombian health system. Sociodemographic, pharmacological, and clinical variables were considered. Results: A total of 9.344 patients had received a macrolide prescription; their median age was 40.1 years (interquartile range: 27.1-53.3 years) and 58.3% were women. The most commonly prescribed macrolide was azithromycin (38.8%) most frequently for Helicobacter pylori infection (15.9%) and pneumonia treatment (15.8%). A total of 31.3% of the prescriptions were used for unapproved indications: common cold (7.8%), COVID-19 (4.0%), and acute bronchitis (3.5%). Residence in the Caribbean region (OR=1.17; 95%CI 1.05-1.31), dental prescriptions (OR=2.75; 95%CI 1.91-3.96), presence of chronic respiratory comorbidities (OR=1.30; 95%CI 1.08-1.56), and prescription of erythromycin (OR=3.66; 95%CI 3.24-4.14) or azithromycin (OR=2.15; 95%CI 1,92-2.41) were associated with a higher probability of macrolide use for unapproved indications while being 18-64 years old (OR=0.81; 95%CI 0.71-0.93) or 65 years or older (OR=0.77; 95%CI 0.63-0.94) and residing in Bogotá-Cundinamarca (OR=0.74; 95%CI 0.65-0.85) were associated with reduced risk. Conclusions: Most patients received macrolides for respiratory tract infections; erythromycin and azithromycin were used for unapproved indications in people under 18 years of age and those with chronic respiratory diseases.

Análise da utilização de inibidores de bomba de prótons em pacientes internados em um hospital universitário do interior de São Paulo / Analysis of the use of proton pump inhibitors in patients admitted to a university hospital in interior of São Paulo

Introdução: A crença de que o uso de Inibidores de Bomba de Prótons (IBPs) apresenta baixo risco de toxicidade, resultou em um aumento significativo na sua prescrição em nível mundial, esse fator juntamente com a baixa divulgação de orientações, têm contribuído para o aumento das indicações desnecessárias de inibidores de bomba de prótons em nível hospitalar, principalmente para profilaxia. Objetivo: Analisar a utilização dos inibidores de bomba de prótons em pacientes internados nas enfermarias de clínica médica de um Hospital Universitário, visando avaliar suas indicações, tempo de uso, efeitos adversos e impacto financeiro gerado pelo uso inadequado. Métodos: Foram analisados prontuários de pacientes que estiveram internados nas enfermarias de clínica médica do Hospital Municipal Universitário de Taubaté (HMUT) durante os meses de maio a julho de 2020. As indicações adequadas do uso de inibidores de bomba de prótons foram baseadas em diretrizes internacionais do American Journal of Gastroenterology e do American Society of Health-System Pharmacy. Resultados: Identificamos que 297 pacientes (79,6%) usaram inibidores de bomba de prótons em algum momento da internação. O uso desse medicamento foi adequadamente prescrito em 49,8% dos casos. Foi encontrado maior prevalência de pneumonia e diarreia nos pacientes que fizeram uso de inibidores de bomba de prótons a longo prazo. O custo anual associado as prescrições indevidas foram de R$24.736,40. Conclusão: Observamos alta prevalência de indicações incorretas dos inibidores de bomba de prótons em ambiente hospitalar, ocasionando gasto desnecessário e possíveis complicações. Faz-se necessário, portanto, elaboração de novos protocolos e maior rigidez nas indicações desses medicamentos no Hospital Municipal Universitário de Taubaté.

Introduction: The belief that the use of Proton Pump Inhibitors (PPIs) presents a low risk of toxicity, resulted in a significant increase in its prescription worldwide, this factor combined with the low disclosure of guidelines, have contributed to the increase in unnecessary indications of at the hospital level, especially for prophylaxis. Objective: To analyze the use of proton pump inhibitors in patients hospitalized in the medical clinic wards of a University Hospital, in order to evaluate their indications, time of use, adverse effects and financial impact generated by inadequate use. Methods: Medical records of patients who were admitted at the Municipal University Hospital of Taubaté during the months of May to July 2020 were analyzed. The appropriate indications for the use of proton pump inhibitors were based on the international guidelines of the American Journal of Gastroenterology and the American Society of Health-System Pharmacy. Results: We identified that 297 patients (79.6%) used proton pump inhibitors at some point in hospitalization. The use of this drug was adequately prescribed in 49.8% of the cases. A higher prevalence of pneumonia and diarrhea was found in patients who used proton pump inhibitors in the long term. The annual cost associated with undue prescriptions was R$24,736.40. Conclusion: We observed a high prevalence of incorrect indications of proton pump inhibitors s in the hospital environment, causing unnecessary expenses and possible complications. It is necessary, therefore, the elaboration of new protocols and greater rigidity in the indications of these drugs at the Municipal University Hospital of Taubaté.

Conhecimento dos prescritores sobre medicamentos potencialmente inapropriados para idosos em uma Unidade Básica de Saúde / Prescribers' knowledge of potentially inappropriate medications in older adults in a Primary Care Unit

Introdução: O conhecimento dos prescritores sobre medicamentos potencialmente inapropriados (MPI) pode reduzir o risco de resultados adversos à saúde em idosos, uma vez que esses medicamentos podem trazer mais risco do que benefício a esses pacientes. O objetivo deste estudo é obter informações sobre o conhecimento dos prescritores em relação aos cuidados na prescrição de medicamentos para idosos e analisar o conhecimento destes em relação a critérios explícitos de classificação de MPI.Métodos: Trata-se de um estudo exploratório e observacional, de delineamento transversal, desenvolvido com a aplicação de questionário on-line respondido de forma anônima por prescritores de uma unidade básica de saúde.Resultados: Dos 20 profissionais que responderam ao questionário, 9 eram professores, 7 médicos residentes e 4 médicos contratados. Em relação aos idosos, 70% dos prescritores percebem boa adesão ao tratamento e 40% maior frequência de reações adversas a medicamentos, quando comparados à população em geral. Somente 30% dos profissionais relataram conhecimento sobre algum critério de classificação de MPI, e 25% destes já utilizou/utiliza algum dos critérios na prática clínica. Porém, os prescritores citaram as classes mais presentes no Critério de Beers para MPI como candidatas à desprescrição e ajuste de dose.Conclusão: O conhecimento e aplicação de critérios de classificação de MPI na prática clínica é ainda incipiente, mesmo em Unidade vinculada a Hospital Universitário.

Introduction: Knowledge of potentially inappropriate medications (PIMs) may reduce the risk of adverse health outcomes in older patients, given that PIMs may be more harmful than beneficial to this population. To investigate prescribers' knowledge of appropriate drug prescription in older adults and evaluate their knowledge of explicit criteria for PIM classification.Methods: We conducted a cross-sectional, exploratory, observational study. We developed an online questionnaire, which was anonymously answered by prescribers from a primary care unit.Results: A total of 20 prescribers answered the questionnaire, of whom 9 were professors, 7 were medical residents, and 4 were physicians. In older patients, 70% of prescribers reported good adherence to treatment and 40% reported a higher rate of adverse drug reactions compared with the general population. Only 30% of prescribers reported some knowledge of the criteria for PIM classification, and 25% of them had already used/use some of the criteria in clinical practice. However, the most prevalent drug classes in the Beers Criteria for PIM were mentioned by prescribers as potentially requiring deprescription and dose adjustment.Conclusion: Knowledge and application of the PIM classification in clinical practice is still incipient, even in a primary care unit affiliated with a teaching hospital.

Potential medication incompatibilities in pediatric oncology prescriptions

Introduction: Pediatric oncology patients have a limited number of venous access routes and need a large number of drugs during hospitalization. This study evaluates potential medication incompatibilities (MI) in pediatric oncology prescriptions and identifies possible factors associated with the risk of their occurrence. Methods: This cross-sectional study evaluated prescriptions from a tertiary universitary hospital from December 2014 to December 2015. The association between variables and the risk of potential incompatibilities between drugs was determined by Student's t-test and Pearson's chi-square, considering p < 0.05 significant. The odds ratio was calculated considering a 95% confidence interval for each drug. Results: 385 prescriptions were evaluated. The mean age of 124 patients was 9.22 years old (SD = ± 5.10), and 50.65% were male. The most frequent diagnosis and reason for hospitalization were leukemia (27.30%) and chemotherapy (36.10%). The totally implantable catheter was the most commonly used venous access (61.30%). In 87.5% of prescriptions, there was the possibility of MI, and 2108 incompatibilities were found, considering 300 different combinations between two drugs. Age, diagnosis, reason for hospitalization, and type of venous access were risk factors for potential incompatibilities (p < 0.05). The following drugs present higher risk of potential incompatibilities: leucovorin, sodium bicarbonate, cefepime, diphenhydramine, dimenhydrinate, hydrocortisone, and ondansetron, with a significant odds ratio. Conclusion: The possibility of MI in prescriptions for pediatric oncology patients is frequent. Thus, the identification of risk factors may contribute to patient safety and to the rational use of drugs.

Avaliação do manejo médico no atendimento de cefaleia na sala de urgência e emergência do Hospital Regional de Barbacena - MG / Evaluation of medical management in the treatment of headache in the urgency and emergency room of the Hospital Regional de Barbacena - MG

Introdução: O manejo da cefaleia nas salas de urgência e emergência deve ser baseada em uma anamnese detalhada para que o diagnóstico e tratamento sejam adequados, entretanto não é o que se encontra nos atendimentos. Objetivo: Avaliar o manejo do atendimento das cefaleias em uma sala de Urgência e Emergência. Métodos: Estudo de corte transversal retrospectivo, realizado através da análise de dados de 1317 prontuários eletrônicos de pacientes com queixa de cefaleia que procuraram o serviço de emergência do Hospital Regional de Barbacena durante o período de 01 de janeiro de 2017 a 30 de junho de 2019. Os diagnósticos relatados nos prontuários foram classificados de acordo com os critérios da Classificação Internacional das Cefaleias (ICHD-3). Os dados foram submetidos à análise estatísticas, pelo teste de qui-quadrado. Considerou-se diferenças estatisticamente significativas aquelas cujo valor p≤0,05. Resultados: Do total de prontuários, três foram excluídos, sendo analisados 1314. Entre os prontuários analisados, 73,21% apresentaram diagnósticos iniciais eram cefaleia, 16,67% migrânea e 10,12% cefaleia do tipo tensão. Já no diagnóstico final, cefaleia correspondeu a 59,67%, migrânea a 17,95% e cefaleia do tipo tensão a 8,52%. Em relação ao tratamento, foi receitado opioides para 43,99% dos pacientes e para o restante foram prescritos medicamentos não opioides. Conclusão: O trabalho sugeriu falha no manejo da cefaleia nas salas de urgência e emergência, provavelmente pela limitação do conhecimento dos profissionais de saúde acerca da dor de cabeça. O que acarretou no grande número de diagnósticos inespecíficos e inadequada abordagem terapêutica.

Introduction: Detailed clinical evaluation should be the basis for the proper management of headaches in emergency rooms, in order to allow adequate diagnosis and treatment. However, this is not usually observed on clinical rounds. Objective: To evaluate the management of headache consultations in an emergency rooms. Methods: This is a cross-section study was performed analyzing data from 1,317 electronic medical records of patients with headache complaints who sought treatment at the Barbacena City Regional Hospital's between January 1, 2017, and June 20, 2019. Medical records were classified according to the International Classification of Headache Disorders (ICHD-3). The data collected were statistically analyzed using chi-square tests. The study considered a p-value≤0.05 to define statistically significant differences. Results: Three medical records were excluded and 1,314 were analyzed. Among the medical records analyzed, 73.21% of initial diagnoses were classified as headache, 16.67% as migraine, and 10.12% as tension-type headache. Headache corresponded to 59.76% of final diagnoses, migraine to 17.95%, and tension-type headache to 8.52%. Regarding the treatment, 43.99% of patients were prescribed opioids for the remaining were prescribed nonopioid medications. Conclusion: The study suggests that the management of headaches is inadequate in emergency rooms, probably due to limited knowledge of health professionals about headache. This resulted in a large number of nonspecific diagnoses and inadequate therapeutic approaches.

Effectiveness, safety and implementation results of the strategies aimed at the safe prescription of medications in university hospitals in adult patients. Systematic review / Efectividad, seguridad y resultados de implementación de estrategias dirigidas al proceso de prescripción segura de medicamentos en hospitales universitarios en pacientes adultos. Revisión sistemática

Abstract Introduction A broad range of practices aimed at improving the effectives and safety of this process have been documented over the past few years. Objective To establish the effectiveness, safety and results of the implementation of these strategies in adult patients in university hospitals. Methodology A review of systematic reviews was conducted, in addition to a database search in the Cochrane Library of Systematic Reviews, Embase, Epistemonikos, LILACS and gray literature. Any strategy aimed at reducing prescription-associated risks was included as intervention. This review followed the protocol registered in the International Prospective Registry of Systematic Reviews (PROSPERO): CRD42020165143. Results 7,637 studies were identified, upon deleting duplicate references. After excluding records based on titles and abstracts, 111 full texts were assessed for eligibility. Fifteen studies were included in the review. Several interventions grouped into 5 strategies addressed to the prescription process were identified; the use of computerized medical order entry systems (CPOE), whether integrated or not with computerized decision support systems (CDSS), was the most effective approach. Conclusions The beneficial effects of the interventions intended to the prescription process in terms of efficacy were identified; however, safety and implementation results were not thoroughly assessed. The heterogeneity of the studies and the low quality of the reviews, preclude a meta-analysis.

Resumen Introducción En los últimos años se han documentado gran variedad de prácticas dirigidas a mejorar la efectividad y la seguridad de este proceso. Objetivo Establecer la efectividad, seguridad y resultados de implementación de estas estrategias en pacientes adultos en hospitales universitarios. Metodología Se realizó una revisión de revisiones sistemáticas. Igualmente, la búsqueda en las bases de datos de la Biblioteca Cochrane de Revisiones Sistemáticas, Medline, Embase, Epistemonikos, LILACS y literatura gris. Se incluyó como intervención cualquier estrategia dirigida a reducir el riesgo asociado a un error de prescripción. Esta revisión siguió el protocolo registrado en el Registro Prospectivo Internacional de Revisiones Sistemáticas (PROSPERO): CRD42020165143. Resultados Se identificaron 7.637 estudios después de eliminar las referencias duplicadas. Después de la exclusión de registros basados en títulos y resúmenes, se evaluaron 111 textos completos para elegibilidad. Se incluyeron quince estudios en la revisión. Se identificaron varias intervenciones agrupadas en 5 estrategias dirigidas al proceso de prescripción, de las cuales el uso de sistemas computarizados de entrada de órdenes médicas (CPOE) integrados o no a sistemas de soporte de decisión computarizados (CDSS) la estrategia más eficaz. Conclusiones Se identificaron efectos benéficos de las intervenciones dirigidas al proceso de prescripción en términos de eficacia; sin embargo, la seguridad y los resultados de implementación no fueron ampliamente evaluados. La heterogeneidad de los estudios y la baja calidad de las revisiones impiden la realización de un metaanálisis.

Prescrição de medicamentos potencialmente inapropriados para idosos segundo os Critérios de Beers: revisão sistemática / Prescribing potentially inappropriate medications for the elderly according to Beers Criteria: systematic review

Resumo Objetivou-se realizar uma revisão sistemática para identificar e avaliar a prevalência da prescrição de medicamentos potencialmente inapropriados (MPI), segundo os Critérios de Beers, em idosos hospitalizados com ≥65 anos. Foram consultadas cinco bases de dados: BVS, Cochrane Library, CINAHL, MEDLINE e Web of Science. Foram identificados 19 artigos, selecionados a partir de critérios de elegibilidade. A média de idade foi 78,2 anos e o critério mais utilizado para a identificação dos MPI para idosos foi o de Beers 2015 (57,9%). Um total de 221.879 idosos recebeu prescrição inapropriada, a prevalência média foi de 65.0%, com destaque para o sistema gastrointestinal (15,3%) e os inibidores da bomba de prótons (27,7%) como a principal classe de medicamento prescrita. Conclui-se que os Critérios de Beers possibilitaram a identificação da alta prevalência na prescrição dos MPI. Os resultados desta revisão poderão auxiliar na tomada de decisão dos profissionais de saúde, no intuito de se evitar a administração dos MPI e propor melhores práticas que garantam a segurança do idoso hospitalizado.

Abstract The study aimed to perform a systematic review to identify and evaluate the prevalence of potentially inappropriate medicines (PIM) prescriptions for the elderly, according to Beers Criteria, in hospitalized elderly individuals aged 65 years or older. Five databases consulted: VHL; Cochrane Library; CINAHL; MEDLINE and Web of Science. Nineteen articles identified, selected based on eligibility criteria. The mean age was 78.2 years and the most used criterion for the identification of PIM for the elderly was Beers 2015 (57.9%). A total of 221,879 elderly received a prescription for PIM, the mean prevalence was 65.0%, for the gastrointestinal system (15.3%) and proton-pump inhibitors (27.7%) highlighted as the main class of medicine prescribed. It concluded that the Beers Criteria have made it possible to identify the high prevalence in the prescription of PIM. The results of this review may help in the decision making of health professionals, to avoid the administration of PIM and to propose best practices to ensure the safety of the elderly hospitalized.

Introduction: Reviewing the prescription represents an opportunity to correct errors and to optimize pharmacotherapy in vulnerable groups. Objectives: To analyze the pharmacotherapeutic complexity that occurs in the polymedicated patients living in the residential environment. Material and Methods: Descriptive, retrospective and cross-sectional study of therapeutic scheme with indication-prescription elements. Universe: 117 medical records of polymedicated patients aged 60 years and over who reside in nursing homes. Period: June-July 2020. Scenario: all nursing homes in Cienfuegos, Cuba. Dependent variable: pharmacotherapeutic complexity defined by the presence of three or more indicators of the quality of life measured by the exhaustive geriatric assessment, the Cumulative Illness Rating Scale for Geriatrics (CIRS-G) and the STOPP/START criteria. Independent variables: age, sex, disease related to increased drug use, validity, comorbidity, type of prescription, inappropriate medications. Source: individual medical history. Results: Pharmacotherapeutic complexity in polymedicated elderly was identified in 76.9 percent of those inappropriately prescribed, multimorbid (OR = 17.3; 95 percent CI: 16-18.6), functionally dependent (OR = 9.9; 95 percent: 6.8 -13) and elderly people ≥75 years (OR = 5.1; 95 percent CI: 4-6.2). Benzodiazepines were the most inappropriately prescribed group. Antiplatelet agents and statins are the indicated non-prescription drugs. Conclusions: Polymedicated elderly patients living in the residential environment follow prescriptions of frequently used groups/drugs which are related to prescription errors with exposure to inadequate polypharmacy and pharmacotherapeutic complexity with a possible threat to the quality of life of the institutionalized elderly people(AU)

Potentially inappropriate medications, drug-drug interactions, and prescribing practices in elderly patients: a cross-sectional study

SUMMARY OBJECTIVE: To evaluate potentially inappropriate medications, potential drug-drug interactions, and prescribing practices in elderly ambulatory patients. METHODS: We carried out a cross-sectional study on 275 elderly patients attending different outpatient departments. We used the Screening Tool for Older Person's Prescriptions criteria version two to identify potentially inappropriate medications, IBM Micromedex, to categorize potential drug-drug interactions as major and moderate. World Health Organization prescribing indicators were used to evaluate prescribing practices. RESULTS: The prevalence of potentially inappropriate medications in 275 prescriptions was 21.9%. Diclofenac was the most common inappropriate drug (n=23). Metoprolol is the second most inappropriate drug (n=12). Amlodipine and clopidogrel, aspirin and furosemide, and aspirin and spironolactone together accounted for 71.42% of major interactions (n=15). Atorvastatin and clopidogrel was the most common moderate drug-drug interaction in our study (n=24). The average number of drugs per encounter, the percentage of drugs with a generic name, and the percentage of drugs from the essential drugs list must be improved. CONCLUSION: There is a need to provide awareness through education about the explicit criteria to identify potentially inappropriate medications and prescribing indicators that aid in rational prescribing in the elderly.

Prescrição de medicamentos potencialmente inapropriados para idosos: um estudo na Atenção Primária à Saúde / Prescription of potentially inappropriate medications for the elderly: a study in Primary Health Care

Resumo Os idosos são vulneráveis aos riscos do uso de medicamentos, principalmente daqueles considerados potencialmente inapropriados (MPI) em que os riscos superam os benefícios. O estudo buscou avaliar os MPI prescritos na Atenção Primária à Saúde (APS) e seus fatores associados. Realizou-se um estudo transversal, analítico, de março a dezembro de 2019, na APS em Campina Grande, Paraíba, através de entrevistas com 458 idosos. As variáveis independentes abrangeram características socioeconômicas, condição de saúde e utilização de medicamentos e o desfecho foi medicamento classificado como MPI pelo Consenso Brasileiro de Medicamentos Potencialmente Inapropriados. Verificou-se a prescrição de pelo menos um MPI para 44,8% dos idosos e a maioria de atuação no Sistema Nervoso Central (54,4%). No modelo ajustado, depressão (RP=2,01; IC95% 1,59-2,55), utilizar outros medicamentos além dos prescritos (RP=1,36; IC95% 1,08-1,72) e polifarmácia (RP=1,80; IC95% 1,40-2,33) permaneceram como fator associado e autorreferir ser portador de hipertensão arterial sistêmica tornou-se fator de proteção (RP=0,65; IC95% 0,49-0,87). Evidencia-se necessidade de ações que qualifiquem o uso de medicamentos por idosos, de modo a garantir acesso aliado à segurança.

Abstract The elderly population is vulnerable to the risks of the use of medications, especially those considered potentially inappropriate medications (PIMs), in which the risks outweigh the benefits. The study sought to evaluate the PIMs prescribed in Primary Health Care (PHC) and associated factors. A cross-sectional, analytical study was carried out from March to December 2019 in PHC in Campina Grande, Paraíba, through interviews with 458 elderly individuals. The independent variables included socioeconomic characteristics, health status and the use of medications, and the outcome was classified as PIM by the Brazilian Consensus on Potentially Inappropriate Medications. There was a prescription of at least one PIM for 44.8% of the elderly and the majority affecting the Central Nervous System (54.4%). In the adjusted model, depression (PR=2.01; 95%CI 1.59-2.55), using other medications in addition to those prescribed (PR=1.36; 95%CI 1.08-1.72) and polypharmacy (PR=1.80; 95%CI 1.40-2.33) remained an associated factor, and self-reporting systemic arterial hypertension became a protective factor (PR=0.65; 95%CI 0.49-0.87). This reveals the need for actions to monitor closely the use of PIMs by the elderly to ensure access in conjunction with safety.

Physician and patient-related factors associated with inappropriate prescribing to older patients within primary care: a cross-sectional study in Brazil

ABSTRACT BACKGROUND: Physician and patient-related characteristics can influence prescription of medications to older patients within primary healthcare. Use of Brazilian criteria may indicate the real prevalence of prescription of potentially inappropriate medications to this population. OBJECTIVES: To evaluate prescription of potentially inappropriate medications to older patients within primary care and identify patient-related and prescribing physician-related factors. DESIGN AND SETTING: This cross-sectional study was conducted in 22 public primary care facilities in Brazil, among older people (≥ 60 years) who were waiting for medical consultations. METHODS: Interviews were conducted before and after the medical consultations. If the patient received a medical prescription at the consultation, all the drugs prescribed and the physician's medical council registration number were recorded. Prevalence ratios were estimated to ascertain the magnitude of prescription of potentially inappropriate medications, along with patient and physician-related factors associated with such prescription. RESULTS: In total, 417 older patients were included; 45.3% had received ≥ 1 potentially inappropriate medication, and 86.8% out of 53 physicians involved had prescribed ≥ 1 potentially inappropriate medication. The strongest patient-related factor associated with higher prevalence of prescription of potentially inappropriate medications was polypharmacy. Among physician-related factors, the number of patients attended, number of prescriptions and length of medical practice < 10 years were positively associated with prescription of potentially inappropriate medications. CONCLUSIONS: High prevalence of prescription of potentially inappropriate medications was observed. Physician-related characteristics can influence prescription of medications to older people within primary healthcare. This suggests that there is a need for interventions among all physicians, especially younger physicians.

Asociación entre polifarmacia y prescripción inapropiada según la clase social en adultos mayores de Bucaramanga / Association between polypharmacy and inappropriate prescription according to social class in older adults in Bucaramanga

Resumen Introducción: La polifarmacia y la prescripción inapropiada (PI) se han visto relacionadas con múltiples variables, incluidas las de aspecto socioeconómico, sin embargo, la evidencia en esta asociación es escasa y heterogénea. Objetivo: Evaluar la asociación entre la polifarmacia y la prescripción inapropiada de medicamentos en adultos mayores de 60 años según su clase social. Material y métodos: Estudio piloto de diseño descriptivo, corte transversal realizada en la ciudad de Bucaramanga-Colombia, con una muestra de 135 adultos mayores de 60 años. Se realizó una encuesta donde se registraron datos sociodemográficos, estado de salud en el último mes, comorbilidades, medicamentos de uso crónico y escalas de funcionalidad. Resultados: No se encontró asociación estadísticamente significativa entre prescripción inapropiada y polifarmacia con la clase social y el nivel educativo (P=0,639). Sin embargo, el tener una filiación al sistema de seguridad social de tipo subsidiado estuvo significativamente asociada a la infra prescripción (P<0,029). La presencia de ingresos mensuales estuvo asociada con la presencia de polifarmacia (P<0,029) y prescripción inadecuada (P<0,033). Conclusiones: Existe una asociación entre algunas variables socioeconómicas, el número de médicos tratantes y algunas especialidades médicas con presentar polifarmacia y prescripción inapropiada de medicamentos.

Abstract Introduction: Polypharmacy and inappropriate prescribing have been related to multiple variables, including sociodemographic, however the evidence is limited and heterogeneous. Objective: To evaluate the association between polypharmacy and inappropriate prescribing in adults over 60 years old according to their social class. Material and methods: A pilot cross-sectional population-based study in the city of Bucaramanga, Colombia, with a sample of 135 adults over 60 years old. A survey was conducted where sociodemographics, health status in the last month, comorbidities, drugs of chronic use and functionality according to scales were registered. Results: No statistical association was found between inappropriate prescribing and Polypharmacy amongst social class and education level (P=0.639). Nevertheless, having an affiliation with a subsidized social security system was significantly associated with infra prescription (P <0.029). The existence of monthly income was associated with the presence of polypharmacy (P <0.029) and inadequate prescribing (P <0.033). Conclusions: There exists an association between some socioeconomic variables, the number of practicing physicians and some medical specialties with polypharmacy and inadequate prescription of drugs.

Criterios de medicación potencialmente inapropiada para el anciano: una propuesta cubana / Medication approaches potentially inappropriate for the elderly: a Cuban proposal

Introducción: El impacto de la prescripción inapropiada de fármacos en el anciano ha llevado al desarrollo de métodos para su reducción en varias partes del mundo. Objetivo: Diseñar y validar los criterios de medicación potencialmente inapropiada en el anciano, adaptados al entorno sociosanitario de Cuba. Métodos: Se realizó una investigación cualitativa, en la cual los criterios fueron validados por medio de la metodología Delphi, por un comité de expertos (especialistas en medicina geriátrica y clínica de diferentes zonas geográficas del país), y se les calculó la consistencia interna mediante el coeficiente alfa de Cronbach. Resultados: Los criterios quedaron estructurados en tres listas: 1) medicación potencialmente inapropiada, medicamento indicado no prescripto, cuando no existe contraindicación para su uso; 2) medicación potencialmente inapropiada independiente del diagnóstico o la condición clínica; 3) medicación potencialmente inapropiada dependiente del diagnóstico o la condición clínica. Conclusiones: Se demostró la validez del contenido y la adecuada consistencia interna de los criterios diseñados para la identificación de medicación potencialmente inapropiada en el anciano.

Introduction: The impact of inappropriate prescription of medication in the elderly has led to the development of methods for its reduction in several parts of the world. Objective: To design and validate the medication approaches potentially inappropriate in the elderly, adapted to the socio-sanitary environment of Cuba. Methods: A qualitative investigation was carried out, in which the approaches were validated by means of the Delphi methodology, by an experts committee (specialists in geriatrics medicine and clinic from different geographical areas of the country), and the internal consistency was calculated by means of the alpha coefficient of Cronbach. Results: The approaches were structured in three lists: 1) potentially inappropriate medication, advised medication non prescribed, when contraindication doesn't exist for its use; 2) medication potentially inappropriate, independent from the diagnosis or clinical condition; 3) potentially inappropriate medication, depending on the diagnosis or clinical condition. Conclusions: The validity of the content and the appropriate internal consistency of the designed approaches for the medication identification potentially inappropriate in the elderly were demonstrated.

Potentially inappropriate prescribing in older adults in Mexico / Prescripción potencialmente inapropiada en adultos mayores en México

ABSTRACT OBJECTIVE To identify and quantify potentially inappropriate prescribing (prescripción potencialmente inapropiada, PPI) and other drug prescribing problems in public health care services in a population-based study at the three existing levels of complexity in Mexico. METHODS Descriptive analysis of the Study on Satisfaction of Users of the Social Protection System in Health 2014-2016, prescription and drug supply section, to obtain the prevalence of PPI in older adults (≥ 65 years), based on Beers, STOPP, Prescrire and BSP listings using AM (older adults) prescription indicators, one for each listing. RESULTS Most older adults (67%) were prescribed at least one medication, with a mean of 2.7 medications per prescription. The PPI prevalence was 74% according to the BSP criteria, 67% according to the STOPP listing, 59% with the Beer criteria, and 20% with Prescrire. The most frequent PPI prescriptions were NSAIDs, vasodilators and sulfonylureas. CONCLUSIONS The use of PPIs in AM is high in Mexico. The higher prevalence found in this study may reflect the use of a source with population representativeness. The partial use and adaptations of the criteria make difficult comparing the studies; however, the STOPP criteria are the ones with the highest prevalence, as they cover a greater number of drugs and their use is more common in the first level of care.

RESUMEN OBJETIVO Identificar y cuantificar la prescripción potencialmente inapropiada (PPI) y otros problemas en la prescripción de medicamentos en los servicios públicos de atención médica en un estudio poblacional en los tres niveles de complejidad existentes en México. MÉTODOS Análisis descriptivo del Estudio de Satisfacción de Usuarios del Sistema de Protección Social en Salud 2014-2016, sección de prescripción y surtimiento de medicamentos, para obtener la prevalencia de PPI en adultos mayores (≥ 65 años) con base en listados Beers, STOPP, Prescrire y BSP mediante indicadores de prescripción en AM, uno por cada listado. RESULTADOS Al 67% de los AM se les prescribió al menos un medicamento, con una media de 2.7 medicamentos por receta. La prevalencia de PPI fue del 74% según los criterios BSP, del 67% según el listado STOPP, del 59% con los criterios Beer y del 20% con Prescrire. Las prescripciones PPI más frecuentes fueron los AINES, vasodilatadores y las sulfonilureas. CONCLUSIONES El uso de PPI en AM es alto en México. La mayor prevalencia encontrada en este estudio puede ser reflejo de la utilización de una fuente con representatividad poblacional. La utilización parcial y adaptaciones de los criterios dificultan la comparabilidad entre estudios, sin embargo, los criterios STOPP son los que más altas prevalencias han presentado debido a que abarca un mayor número de medicamentos y su uso más habitual en el primer nivel de atención.

Potentially inappropriate medication use in older adults: prevalence and physician knowledge / Medicamentos potencialmente inapropriados para idosos: prevalência de uso e conhecimento médico

OBJECTIVE: To analyze the frequency, profile, and additional variables associated with the prescription of potentially inappropriate medications (PIM) to older adults in primary care, and evaluate physicians' knowledge about these medications. METHODS: A cross-sectional study was conducted based on data from patient records for the period of January 2014 to December 2017 in a city located in the state of Minas Gerais. The frequency of PIM use was evaluated based on the 2019 Beers-Fick criteria. Physician knowledge was evaluated using a validated questionnaire as a primary data source. RESULTS: In a sample of 423 older adults, 75.89% (n = 321) used at least one PIM, the most common of which were medications used to treat central nervous system disorders (48.00%; n = 203). Most participants were female (62.41%; n = 264) and 70 years or older (69.50%; n = 294). When presented with clinical cases illustrating common situations in the management of older patients, 53.33% of physicians (n = 8) answered four or five questions correctly out of a possible seven; 13.33% (n = 2) answered six questions correctly; and 33.33% (n = 5) obtained three correct answers or fewer. CONCLUSIONS: These findings showed a high frequency of PIM use among older adults treated in Primary Health Care settings, with medications used in the treatment of central nervous system disorders. Our results highlight the importance of continuing education for health professionals and improved assessments of the medication available in the Unified Health System (Sistema Único de Saúde; SUS) for use in older adults, especially those taking multiple medications.

OBJETIVOS: Analisar a frequência, o perfil e os fatores associados à prescrição de medicamentos potencialmente inapropriados (MPI) aos idosos na Atenção Primária à Saúde, além de avaliar o conhecimento dos médicos sobre esses medicamentos. METODOLOGIA: Trata-se de um estudo transversal, cujas informações foram coletadas de prontuários dos pacientes, referentes ao período de janeiro de 2014 a dezembro de 2017, em um município localizado no estado de Minas Gerais. Para análise da frequência de uso de MPI, utilizou-se o critério Beers-Fick de 2019. Para avaliação do conhecimento médico, utilizou-se uma fonte primária de informação, um questionário validado. RESULTADOS: Dos 423 idosos, 75,89% (n=321) utilizavam pelo menos um MPI e a classe mais utilizada foi do sistema nervoso central (48,00%; n=203). Houve maior prevalência no sexo feminino (62,41%; n=264) e em idosos com idade ≥70 anos (69,50%; n=294). Em relação aos casos clínicos apresentados para avaliar o conhecimento dos médicos referentes às situações comuns no cuidado à saúde do idoso, 53,33% (n=8) acertaram quatro ou cinco questões das sete existentes, enquanto 13,33% (n=2) responderam corretamente a seis perguntas e 33,33% (n=5) obtiveram três ou menos acertos. CONCLUSÕES: Os resultados evidenciaram alta taxa de prescrição de MPI entre os idosos da Atenção Primária à Saúde, destacando-se os medicamentos que são destinados ao tratamento de doenças do sistema nervoso central. Ressalta-se a importância da educação continuada desses profissionais de saúde e a melhor avaliação de medicamentos incorporados ao Sistema Único de Saúde (SUS) e destinados à população geriátrica, sobretudo o idoso polimedicado.

Los médicos y la industria farmacéutica: impacto sobre actitudes y hábitos de prescripción / Physicians and the pharmaceutical industry: impact on prescription attitudes and habits

Resumen Introducción: La relación médico-industria farmacéutica (IF) se ha identificado como un problema ético por favorecer conflictos de interés derivados de los beneficios que reciben los médicos y que pueden afectar su juicio clínico. Objetivo: Identificar la frecuencia de participación de médicos en actividades financiadas por la IF, las actitudes de estos profesionales hacia los representantes de la IF, su conducta prescriptiva y la asociación de sus características y del trabajo con la participación en actividades financiadas por la IF. Método: Encuesta transversal a médicos internistas y cardiólogos. El cuestionario incluyó características de los médicos y centro de trabajo, participación en actividades financiadas por la IF, actitudes hacia los representantes y conducta de prescripción. Resultados: Se analizaron 455 cuestionarios, 78.5 % de los encuestados tuvo conocimiento de la relación médico-IF, la mayoría respondió reunirse con representantes de la IF, 30 % indicó haber recibido subsidios financieros y 10 % consideró que los obsequios afectan su prescripción. Tener conocimiento previo de la relación médico-IF se asoció con menor participación en actividades educativas financiadas por por la IF. Conclusión: Las prácticas y preferencias hacia la IF muestran la necesidad de diseñar estrategias para evitar la prescripción inapropiada.

Abstract Introduction: The physician-pharmaceutical industry relationship has been identified as an ethical problem, due to conflicts of interest motivated by the benefits that doctors receive and that can affect their clinical judgment. Objective: To identify the frequency of physicians participation in activities financed by the pharmaceutical industry (PI), their attitudes towards PI representatives (PIRs), their prescriptive behavior and the association between their characteristics and their workplace with their participation in activities financed by the PI. Method: Cross-sectional survey to internists and cardiologists. The questionnaire included characteristics of the doctors and their workplace, participation in activities financed by the PI, attitudes towards PIRs, and prescription behavior. Results: 455 questionnaires were analyzed; 78.5 % of surveyed subjects were aware of the physician-PI relationship, the majority acknowledged meeting with PIRs, 30 % indicated having received financial subsidies and 10 % considered that gifts affect their prescription. Having prior knowledge of the physician-PI relationship was associated with less participation in PI-financed educational activities. Conclusion: Practices and preferences towards the PI show the need to design strategies to avoid inappropriate prescription.
