RESUMEN
OBJECTIVE: To assess regional and national mortality and years of life lost (YLL) related to adverse drug events in Brazil. METHODS: This is an ecological study in which death records from 2009 to 2018 from the Mortality Information System were analyzed. Codes from the International Classification of Diseases 10th revision (ICD-10) that indicated drugs as the cause of death were identified. The number of deaths and the YLL due to adverse drug events were obtained. Crude, age- and gender-specific, and age-adjusted mortality rates and YLL rates per 100,000 inhabitants were formed by year, age group, gender, and Brazilian Federative Unit. Rate ratios were calculated by comparing rates from 2009 to 2018. A joinpoint regression model was applied for temporal analysis. RESULTS: For the selected ICD-10 codes, a total of 95,231 deaths and 2,843,413 YLL were recorded. Mortality rates from adverse drug events increased by a mean of 2.5% per year, and YLL rates increased by 3.7%. Increases in rates were observed in almost all age groups for both genders. Variations in rates were found between Federative Units, with the highest age-adjusted mortality and YLL rates occurring in the Distrito Federal. CONCLUSIONS: The numbers and rates of deaths and YLL increased during the study period, and variations in rates of deaths and YLL were observed between Brazilian Federative Units. Information on multiple causes of death from death certificates can be useful for quantifying adverse drug events and analyzing them geographically, by age and by gender.

INTRODUCTION: Potential drug interactions exert a significant impact on patient safety, especially within intricate onco-hematological treatments, potentially resulting in toxicity or treatment failures. Despite the availability of databases for potential drug interaction investigation, persistent heterogeneity in concordance rates and classifications exists. The additional variability in database agreement poses further complexity, notably in critical contexts like onco-hematology. AIM: To analyze the concordance of two databases for researching potential drug interaction in prescriptions for hematological patients at a University Hospital in the Midwest region of Brazil. METHOD: Cross-sectional study developed in a Brazilian hospital. The search for potential drug interaction was conducted in Micromedex® and UpToDate®. The variables were: the presence of potential drug interaction, severity, mechanism, management, and documentation. Data was analyzed in terms of frequency (absolute and relative), Cohen's kappa, and Fleiss kappa. RESULTS: The presence of potential drug interaction, showed a lack of concordance between the databases (k = -0.115 [95% CI: 0.361-0.532], p = 0.003). Regarding the mechanism, a strong agreement was observed (k = 0.805, p < 0.001 [95% CI: 0.550-0.941]). The management concordance showed a fair agreement, 46.8% (k = 0.22, p < 0.001 [95% CI: 0.099-0.341]). Stratifying the categories, significant concordance was observed in "Adjustment of dose + Monitoring" (k = 0.302, p = 0.018) and "Monitoring" (k = 0.417, p = 0.001), while other categories did not reach statistical significance. CONCLUSION: Our study emphasizes the variability in potential drug interaction research, revealing disparities in severity classification, management recommendations, and documentation practices across databases.

OBJECTIVE: To describe the frequency and characteristics of hospitalizations for/with adverse drug events in the Brazilian unified health system routine data. METHODS: Nationwide retrospective study using data obtained from a period of ten years from the Brazil Hospital Information System (SIH-SUS), an administrative database that registers hospitalizations in the unified health system. We selected hospitalizations with primary and/or secondary diagnosis related to adverse drug events according to a list of validated International Classification Disease 10th edition (ICD-10) codes. These events were described according to year, age group, sex, length of hospital stay, mortality, hospital costs, Brazilian geographical region, and category of ICD-10 codes. Crude hospitalization rates of adverse drug events per 100,000 inhabitants were obtained and Joinpoint Regression was used to analyze temporal changes in these rates along the years. The most frequent ICD-10 codes were also identified. RESULTS: Over ten years, 603,663 hospitalizations in Brazil were found in the database, out of which 2.5% of the patients died. Though 2009 had the highest prevalence of hospitalization per 100,000 inhabitants (32.57), no significant annual change in rates was found for the entire period. All age groups and sexes presented a jointpoint in temporal series; however, only women had a significative increase trend. The most frequent codes were from the chapter of mental and behavioral disorders (F19.2, F19.0, and F19.5 codes). CONCLUSIONS: The database methodology can be useful to estimate frequencies of adverse drug events and perform characterization nationwide and to help monitor morbidity along the years.

PURPOSE: Adverse drug events are related to negative outcomes in healthcare, including hospitalization, increased duration of hospital stay and death. The aim of this study was to conduct a systematic review to evaluate hospitalizations and deaths related to adverse drug events worldwide, reported in studies with national coverage. METHODS: The protocol was registered in PROSPERO (CRD42020157008). We performed a systematic search on Medline, Embase, CINAHL, LILACS, and the Cochrane Library (until March 2020) using pre-specified terms. We included published studies that reported data on hospitalizations and/or deaths related to adverse drug events from a national perspective and the use of secondary data as a source of information. Two reviewers independently extracted and synthesized data. The quality of the studies was assessed using an adapted version of the Joanna Briggs Institute critical appraisal checklist for prevalence studies. Narrative summaries of findings were undertaken. RESULTS: Among 59,336 citations, 62 studies were included for data extraction and synthesis. Among these studies, 41 studies included the outcome of hospitalization, 16 included the death outcome, and five included both outcomes. Administrative databases regarding discharges and registries of vital statistics were the most common sources of information. The relative frequency of hospitalizations ranged from 0.03% to 7.3%, and from 9.7 to 383.0/100,000 population, whereas mortality rate ranged from 0.1 to 7.88/100,000 population. CONCLUSION: Our study highlights information about adverse drug events using large administrative databases in a national scenario and provides an overview of databases and methods implemented to detect adverse drug events.

OBJECTIVE: To describe the frequency and characteristics of adverse drug events in pediatric inpatients in a Brazilian tertiary teaching hospital. METHODS: A cross-sectional study was conducted by retrospective and manual chart review of 240 pediatric admissions to identify adverse drug events using 17 triggers. When triggers were detected in the chart, reviewers investigated the chart in depth to decide whether an event occurred. Consensus about the occurrence of the event was obtained in meeting with a healthcare team. Events were classified by harm category and drugs were classified according to the Anatomical Therapeutic Chemical Classification. Patients who had suffered were compared to those who had not experienced events using the chi-squared test and the Mann-Whitney U test. RESULTS: A total of 62 adverse events were found, and 18.8% of the patients had at least one event. Adverse events rates were 25.83 per 100 admissions, 20.27 per 1000 patient-days, 25.94 per 1000 drugs, and 2.12 per 1000 drug doses. All events found were classified as temporary harm, and cardiovascular drugs were most frequently related to events. Groups of patients with and without event were segregated (p<0.05) by the length of stay, number of drugs, and drug doses. CONCLUSION: The use of triggers demonstrated its utility in a pediatric setting by identifying harm. Adverse events rates were found to be higher than those of previous studies, but the harm rate was lower than other studies. This study enables the measurement of adverse events in order to define strategies to mitigate or reduce harm.

Background Prescription evaluation by pharmacists has potential to improve pharmacotherapy management. It requires the use of robust methods to identify drug-related problems (DRP), which are important issues in pharmacotherapy. Objective To evaluate the applicability and reliability of Grupo de Investigação em Cuidados Farmacêuticos (GIGUF) method for prescription analysis, identification and classification of drug-related problems in inpatients prescriptions. Setting Department of Medical Clinic of a tertiary and teaching Brazilian hospital. Method An observational and retrospective study of identification and classification of drug-related problems. GIGUF method was used to evaluate prescriptions of hematological patients hospitalized between August and October 2015. The problems were categorized using GICUF-method classification. Three pharmacists performed inter-rater agreement analysis of the method using Kappa. Differences in prevalence of DRP was calculated by age, sex, pharmacotherapy complexity, length of stay and number of drugs. Main outcome measure (a) frequency and characteristics and (b) inter-rater agreement in identification and classification of the drug-related problems. Results A total of 211 problems were identified and 'inadequate dosing' was the most common problem. There was an association between the occurence of a drug-reklated problem and complexity of pharmacotherapy (p = 0.001) and number of drugs used (p = 0.010). The overall inter-rater agreement was moderate (k = 0.44 IC 95% 0.34-0.55) and the problem 'not suitable drug' (k = 0.55 IC 95% 0.44-0.66) had greater inter-rater agreement. Conclusion The method "Evaluation Drug Use Process" was useful for prescription analysis since it made the identification and classification of DRPs possible. The method demonstrated a moderate inter-rater agreement, and can contribute to pharmacotherapy management by hospital pharmacists.

Resumo Objetivo Analisar o perfil farmacoterapêutico dos idosos atendidos em um Centro de Referência em Atenção à Saúde da Pessoa Idosa quanto ao uso de medicamentos potencialmente inapropriados (MPI) por meio de três critérios de rastreamento e determinar fatores associados à prescrição de MPI. Método Estudo transversal com dados obtidos por revisão retrospectiva dos prontuários de idosos, atendidos entre 2017 e 2018 por médico geriatra. Para identificar os MPI, utilizaram-se os Critérios de Beers, o Screening Tool of Older Persons' Potentially Inappropriate Prescriptions (STOPP) e o Consenso Brasileiro de Medicamentos Potencialmente Inapropriados para Idosos. Características relacionadas ao perfil sociodemográfico (idade e sexo), de hábitos de vida (tabagismo e consumo de álcool), clínico (doenças) e farmacoterapêutico (medicamentos e Índice de Complexidade da Farmacoterapia - ICFT) foram avaliadas. Resultados Foram analisados 406 prontuários e identificados 3.059 medicamentos prescritos, dos quais 32,1% são MPI segundo Critérios STOPP, 14,4% pelo Consenso Brasileiro e 11,7% pelos Critérios de Beers. No total, 81,1% dos idosos apresentaram ao menos um MPI. Regressão de Poisson demonstrou associação entre a prescrição de MPI com polifarmácia, maior número de sinais e sintomas e maior valor de ICFT em ao menos um dos critérios. A força de concordância entre os critérios de MPI foi moderada. Conclusões A maioria dos prontuários analisados possuíam ao menos um MPI prescrito, sendo que os Critérios STOPP identificaram uma maior quantidade de MPI. Estratégias devem ser implementadas para melhorar a farmacoterapia dos idosos com atenção para os que apresentam fatores associados a MPI em seu perfil.
Abstract Objective To analyze the pharmacotherapeutic profile of the old people assisted at a Reference Center in Health Care for Old People regarding the use of potentially inappropriate medications (PIM) using three screening criteria and to determine factors associated with the prescription of PIM. Method Cross-sectional study with data obtained by retrospective review of the medical records of the old people, attended between 2017 and 2018 by a geriatric doctor. To identify the PIM, the Beers Criteria, the Screening Tool of Older Persons' Potentially Inappropriate Prescriptions (STOPP) and the Brazilian Consensus on Potentially Inappropriate Medications for Old People were used. Characteristics related to the sociodemographic profile (age and sex), lifestyle (smoking and alcohol consumption), clinical (diseases) and pharmacotherapeutic (medications and Medication Regimen Complexity Index - MRCI) were evaluated. Results 406 medical records were analyzed and 3,059 prescription medications were identified, of which 32.1% are PIM according to STOPP Criteria, 14.4% by the Brazilian Consensus and 11.7% by the Beers Criteria. In total, 81.1% of the old people had at least one PIM. Poisson regression demonstrated an association between the prescription of PIM with polypharmacy, a greater number of signs and symptoms and a higher MRCI value in at least one of the criteria. The strength of agreement between the PIM criteria was moderate. Conclusions Most of the analyzed medical records had at least one prescribed PIM, and the STOPP Criteria identified a greater amount of PIM. Strategies must be implemented to improve the pharmacotherapy of old people with attention to those who have factors associated with PIM in their profile.
RESUMEN
Abstract Objective: To describe the process of translation, adaptation, and validation of the Brazilian Portuguese version of the Pediatric Trigger Toolkit: Measuring Adverse Drug Events in the Children's Hospital. Methods: The validation process for the research instrument was carried out in five steps: (I) translation from English into Brazilian Portuguese by two independent translators; (II) synthesis of the translated versions; (III) adaptation of the triggers to the Brazilian context using a modified Delphi method carried out in two rounds; (IV) application of the research instrument in the review of 240 hospitalizations during 2014; and (V) back-translation from Brazilian Portuguese to English. Results: The translation step resulted in two versions, which were then synthesized to obtain equivalence within the Brazilian cultural context. The process of adapting the research instrument allowed the inclusion and adaptation of some triggers, as well as the exclusion of others, based on the consensus reached among experts during the Delphi step. The positive predictive value of the research instrument was 13.51%, and the antihistamine trigger presented the highest positive predictive value. Conclusion: The research instrument can be used to track the occurrence of adverse drug events in pediatric patients in Brazilian hospitals. Despite the adjustments made, triggers that were not identified or that had low positive predictive value can suggest the need for additional changes. However, more studies are needed before modifying or removing a trigger.
Resumo Objetivo: Descrever o processo de tradução, adaptação e validação para o português do Pediatric Trigger Toolkit: Measuring Adverse Drug Events in the Children's Hospital. Métodos: O processo de validação do instrumento de pesquisa foi realizado em 5 etapas: (I) tradução do inglês para o português por dois tradutores independentes; (II) síntese das versões traduzidas; (III) adaptação dos rastreadores para realidade brasileira por meio do método Delphi modificado, em duas rodadas; (IV) aplicação do instrumento de pesquisa na revisão de 240 internações de 2014; e (V) retrotradução do português para o inglês. Resultados: A etapa de tradução resultou em duas versões traduzidas, que foram sintetizadas de forma a obter equivalência ao contexto cultural brasileiro. O processo de adaptação do instrumento de pesquisa possibilitou a inclusão e adaptação dos rastreadores, bem como a exclusão de rastreadores segundo consenso obtido entre os especialistas na etapa Delphi. O valor preditivo positivo do instrumento de pesquisa foi de 13,51% e o rastreador anti-histamínico foi o que apresentou maior valor preditivo positivo. Conclusão: O instrumento de pesquisa pode ser utilizado para rastrear a ocorrência de eventos adversos a medicamentos em pacientes pediátricos nos hospitais brasileiros. Apesar das adaptações realizadas, rastreadores que não foram identificados ou com baixo valor preditivo positivo podem indicar, ainda, a necessidade de modificações. Entretanto, mais estudos são necessários antes de modificar ou excluir algum rastreador.

Background Drug-related problems are mostly preventable or predictable circumstances that may impact on health outcomes. Clinical pharmacy activities such as medication therapy management can identify and solve these problems, with potential to improve medication safety and effectiveness. Objective To evaluate ability of medication therapy management service to detect drug-related problems and prevent adverse drug events. This study also aimed to assess the risk factors for drugrelated problem occurrence. Setting Medical intensive care unit of a public tertiary hospital in Brazil. Methods Patients were evaluated by a clinical pharmacist, who provided medication therapy management service. Detected drug-related problems were categorized according to the Pharmaceutical Care Network Europe methodology and analyzed in multinomial regression to identify risk factors. Main outcome measure Potential risk factors for drug-related problem occurrence. Results The proposed medication therapy management service allowed detection of 170 drug-related problems that had potential to reach patients causing harm and other 50 unavoidable adverse events. Drug-related problems identified were more often associated with antibacterial use, caused by improper combinations or inadequate drug dosage. These problems required interventions that were accepted by the multidisciplinary team, resulting in more than 85% adherence and total problem solving. Main risk factors identified were previous diagnosis of kidney injury (OR = 8.38), use of midazolam (OR = 7.96), furosemide (OR = 5.87) and vancomycin (OR = 4.82). Conclusion Medication therapy management proved to be an effective method not only for drug-related problem detection, but also for adverse drug event prevention, contributing to improve patient safety.
