Long-Term Care medicines formularies: any reasons for pharmacists' concern?

Abstract This study aimed to characterize and compare medicines formularies (MFs) used in Long-Term Care (LTC) facilities in Portugal, and to identify the prevalence of Potentially Inappropriate Medicines (PIMs). A systematic contact with LTC facilities was undertaken in December 2021. MFs were systematized according to the Anatomical Therapeutical Chemical classification system (ATC), followed by descriptive content analysis. A structured comparison between MFs developed by public organizations and private LTC facilities was performed. After duplicate removal and exclusion of medicines not for systemic use, two explicit criteria - the Algorithm of medication review in frail older people and the EU(7)-PIM list - were employed for PIMs identification. Five MFs were obtained and assessed. The three MFs developed by private institutions covered 23% of the national LTC facilities and approximately 34% of the national total of beds. Heterogeneity was particularly high for the Alimentary tract and metabolism, Blood and blood-forming organs, Musculoskeletal system, and Respiratory system ATC groups. A PIM prevalence of 29,4% was identified. Medicines distribution between the MFs suggests the need to develop national guidelines towards harmonizing medicines usage in LTC. The prevalence of PIMs found highlights the importance of a particular optimized use of this health technology in aged sub-populations

Potentially inappropriate prescribing among older patients and associated factors: comparison of two versions of STOPP/START criteria

Abstract The study aimed to estimate and compare the prevalence and type of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) between the STOPP/START original (v1) and updated version (v2) among older patients in various settings, as well as associated factors. The study included 440 patients attending a community pharmacy, 200 outpatients and 140 nursing home users. An increase in the prevalence of STOPP v2 (57.9%) compared to v1 (56.2%) was not statistically significant in the total sample and within each setting (p>0.05). A decrease in the prevalence of START v1 (55.8%) to v2 (41.2%) was statistically significant (p<0.001) in the total sample and within each setting (p<0.05). Drug indication (32.9%) and fall-risk medications (32.2%) were most commonly identified for STOPP v2, while cardiovascular system criteria (30.5%) were the most frequently detected for START v2. The number of medications was the strongest predictor for both STOPP v1 and v2, with odds ratio values of 1.35 and 1.34, respectively. Patients' characteristics associated with the occurrence of STOPP and START criteria were identified. According to both STOPP/START versions, the results indicate a substantial rate of potentially inappropriate prescribing among elderly patients. The prevalence of PIMs was slightly higher with the updated version, while the prevalence of PPOs was significantly lower

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.

Avaliação de medicamentos potencialmente inapropriados e da polifarmácia em pacientes idosos em um hospital universitário / Evaluation of potentially inappropriate medications and polypharmacy in elderly patients at a university hospital

Introdução: O Brasil, assim como outros países, vem alterando seu perfil demográfico elevando o número de pessoas idosas, o que repercute em mudanças não só para sociedade, mas também para saúde pública. Este grupo de pacientes é mais vulnerável devido à fisiologia inerente ao envelhecimento, logo se tornam mais propensos ao uso de medicamentos que podem causar outros problemas de saúde. Essa probabilidade de risco é uma preocupação atual e levou a criação de métodos que norteiam os prescritores para adequarem suas terapêuticas neste grupo de pacientes. Um destes métodos é o critério de Beers, que é atualizado periodicamente trazendo uma lista de medicamentos potencialmente inapropriados (MPIs) para idosos. Objetivo: Avaliar a prescrição de pacientes idosos internados no Hospital Universitário da Universidade Federal de Juiz de Fora (HU-UFJF/Ebserh) quanto à prevalência do uso de MPI e polifarmácia, no período de julho a agosto de 2019. Material e Métodos: Estudo observacional descritivo e retrospectivo, cujos dados foram coletados de prontuários pacientes idosos com idade igual ou superior a 65 anos para obtenção dos resultados que foram avaliados estatisticamente. Resultados: Foram avaliados 187 prontuários, e observada prevalência de 80,2% da prescrição de MPIs, sendo os mais prevalentes omeprazol e benzodiazepínicos. A maioria dos pacientes tiveram polifarmácia (95,7%). Conclusão: Os resultados convergem com base no critério de Beers, para necessidade de adequar a terapia de pacientes idosos. É necessário também avaliar os benefícios e alternativas quanto aos MPIs mais prevalentes, além de realizar estudos observacionais sobre possíveis efeitos adversos que possam ser consequência do uso desses medicamentos, com objetivo de aperfeiçoar a terapia farmacológica e aprimorar a farmacoeconomia, melhorando assim a qualidade de vida dos pacientes idosos.

Introduction: Brazil, like other countries, has been changing its demographic profile, increasing the number of elderly people, which reflects in changes not only for society, but also for public health. This group of patients is more vulnerable due to the inherent physiology of aging, so they become more likely to use medications that can cause other health problems. This risk probability is a current concern and has led to the creation of methods that guide prescribers to adapt their therapies in this group of patients. One of these methods is the Beers criterion, which is periodically updated with a list of potentially inappropriate medications (PIM) for the elderly. Objective: To evaluate the prescription of elderly patients hospitalized at the University Hospital of Juiz de Fora (HU-UFJF/Ebserh) regarding the prevalence of the use of PIM and polypharmacy, from July to August 2019. Material and Methods: Descriptive and retrospective observational study, whose data were collected from medical records of elderly patients aged 65 years or older to obtain the results that were statistically evaluated. Results: A total of 187 medical records were evaluated, and a prevalence of 80.2% of the prescription of PIMs was observed, the most prevalent being omeprazol and benzodiazepines. Most patients had polypharmacy (95.7%). Conclusion: The results converge, based on the Beers criterion, for the need to suit the therapy of elderly patients. It is also necessary to evaluate the benefits and alternatives regarding the most prevalent PIMs, in addition to conducting observational studies on possible adverse effects that may be a consequence of the use of these medications, aiming to refine pharmacological therapy and improve pharmacoeconomics, thus improving quality of life of elderly patients.

Polifarmácia, automedicação e uso de medicamentos potencialmente inapropriados: causa de intoxicações em idosos / Polypharmacy, automedication, and the use of potentially inappropriate medications: cause of intoxications in the elderly

Introdução: É fato que os idosos compreendem um grupo etário que cresce exponencialmente no Brasil. Inevitavelmente, a alta demanda da maioria dessa população por medicamentos e serviços de saúde acarreta impacto nas políticas de saúde pública no que tange o esforço necessário para garantir o uso racional de medicamentos, evitar iatrogenia e melhorar a qualidade de vida dos idosos. Medicamentos potencialmente inadequados são aqueles que devem ser evitados em idosos, em que o risco de eventos adversos supera o benefício. Métodos: O estudo, de caráter descritivo e retrospectivo e partindo da pesquisa e análise de dados secundários em saúde, objetivou ampliar o conhecimento sobre o impacto do uso de medicamentos pela população idosa, através da coleta de informações sobre as intoxicações por uso de medicamentos disponíveis no site do DATASUS (departamento de informática do Sistema Único de Saúde). Resultados: Em cerca de dez anos relacionados ao período estudado, entre 2010 a 2020, houveram 2.946 internações de idosos causadas por intoxicações farmacológicas, sendo relevante em número de casos as classes dos anticonvulsivantes, sedativos, hipnóticos, antiparkinsonianos. A região com maior número de casos foi a Sudeste. Há diferenças significativas na probabilidade de intoxicação em idosos, sendo maior nos casos de exposição a álcool, a fármacos analgésicos, antipiréticos e antirreumáticos, e a fármacos com ação no sistema nervoso central. Conclusão: Os resultados encontrados advêm da tendência crescente dos problemas associados ao uso de medicamentos por idosos, tornando-se clara a importância de estratégias efetivas de farmacovigilância voltadas a saúde dessa população.

Introduction: It is a fact that the elderly comprise an exponentially growing age group in Brazil. Inevitably, the high demand of most of this population for medicines and health services impacts public health policies in terms of the effort required to ensure the rational use of medicines, avoid iatrogenesis and improve the quality of life of the elderly. Potentially inappropriate drugs are those that should be avoided in the elderly, where the risk of adverse events outweighs the benefit. Methods: The study, of descriptive and retrospective nature and based on the research and analysis of secondary health data, aimed to broaden knowledge about the impact of the use of medicines by the elderly population, by collecting information on intoxications due to the use of medicines available on the DATASUS (departamento de informática do Sistema Único de Saúde) website. Results: In about ten years related to the studied period, from 2010 to 2020, there were 2,946 hospitalizations of the elderly caused by pharmacological intoxications, being relevant in number of cases the classes of anticonvulsants, sedatives, hypnotics, and antiparkinsonian drugs. The region with the highest number of cases was the Southeast. There are significant differences in the probability of intoxication in the elderly, being greater in cases of exposure to alcohol, analgesic, antipyretic and anti-rheumatic drugs and drugs with action on the central nervous system. Conclusion: The results found show a growing trend of problems associated with the use of medicines by the elderly, making clear the importance of effective pharmacovigilance strategies aimed at the health of this population.

Criterios de Beers para identificar el consumo de medicación potencialmente inapropiada: adaptación para su aplicación en Argentina / Beers criteria to identify the consumption of potentially inappropriate medication: adaptation for its application inArgentina

Introducción. Los Criterios de Beers son los más utilizados para evaluar el uso de medicación potencialmente inapropiada en grandes poblaciones, pero no contemplan algunos medicamentos de uso frecuente fuera de los EE.UU. Objetivo. Realizar una adaptación al contexto de Argentina de los Criterios de Beers publicados en 2019. Métodos. Fue elaborada una lista preliminar de medicación potencialmente inapropiada adaptada a la comercialización local, que luego fue consensuada por un panel de expertos (método Delphi). Resultados. De los 112 medicamentos originales listados en la tabla dos de los Criterios de Beers (en forma individual o como grupo), fueron excluidos 36 por no estar disponibles el país y fueron sumados 23 que no se comercializan en los EE.UU. pero sí en Argentina. Luego de dos rondas y de consensuar la suma a esta lista de dos grupos farmacológicos(antimigrañosos y vasodilatadores periféricos), fue acordado el agregado de picosulfato, bisacodilo, senósidos y cáscara sagrada como medicación potencialmente inapropiada en el grupo de agentes contra el estreñimiento, la fluoxetina entre los inhibidores selectivos de la recaptación de serotonina y el Ginkgo biloba como droga contra la demencia. También hubo consenso en advertir el riesgo de hipotensión ortostática asociado a la tamsulosina, en aconsejar la consideración de la carga anticolinérgica total del esquema terapéutico administrado y en recomendar al paracetamol como primera línea de tratamiento del dolor, asociado o no a opioides. Conclusiones. Contar con una versión de los Criterios de Beers 2019 adaptada al contexto de Argentina contribuirá al desarrollo y monitoreo de intervenciones para prevenir y reducir el consumo de medicación potencialmente inapropiada. (AU)

Introduction.The Beers Criteria is the most widely used criteria to assess the use of potentially inappropriate medication in large populations, but they do not include some medications that are frequently used outside the United States. Objective.To make an adaptation of the Beers Criteria published in 2019 to the context of Argentina. Methods. A preliminary list of potentially inappropriate medication adapted to local market and practice was designed, which was then agreed upon by a panel of experts (Delphi method). Results. Of the 112 original drugs in the table 2 of the Beers Criteria (individually or as a group), 36 were excluded because they were not available in Argentina and 23 locally marketed drugs but not in the US were included. After two rounds and agreeing to add two additional pharmacological groups to this list (antimigraine and peripheral vasodilators), it was decided to add picosulfate, bisacodyl, sennosides and cascara sagrada as potentially inappropriate medication in the group of anti-constipation agents, fluoxetine among. the selective serotonin reup take inhibitors and Ginkgo biloba as an anti-dementia drug. There was also consensus in warning about the risk of orthostatic hypotension associated with tamsulosin,in advising consideration of the total anticholinergic load of the therapeutic regimen administered, and in recommending paracetamol as the first line of pain treatment, associated or not with opioids. Conclusions. Having a version of the Beers Criteria 2019 adapted to the Argentine context will contribute to the development and monitoring of interventions to prevent and reduce the consumption of potentially inappropriate medication.

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.

Las benzodiacepinas fue el grupo más prescrito inadecuadamente. Los antiagregantes plaquetarios y las estatinas son los medicamentos indicados no prescritos. Conclusiones: Los ancianos polimedicados del medio residencial tienen prescripciones de grupos/fármacos de uso frecuente que se relacionan con errores de prescripción, que expone polifarmacia inadecuada y complejidad farmacoterapéutica con posible amenaza a la calidad de vida del geronte institucionalizado(AU)

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)

Medicamentos potencialmente inapropriados prescritos para idosos atendidos na Atenção Primária / Potentially Inappropriate Medications Prescribed for Assisted Elderly in Primary Care

O objetivo do presente estudo foi determinar o perfil dos medicamentos prescritos para pacientes idosos em atenção primária, buscando a ocorrência de medicamentos potencialmente inapropriados (MPI), segundo critérios de Beers e fatores associados. O método consistiu em estudo observacional retrospectivo no período de setembro a outubro de 2015, cujos critérios de inclusão foram prescrições de medicamentos de uso contínuo para pacientes com idade igual ou superior a 60 anos. Foram analisadas prescrições de 820 pacientes. A presença de MPI ocorreu em 35,4% das prescrições. Estas apresentaram maior ocorrência para o gênero feminino OR: 1,33 (0,97 - 1,80), pacientes com idade igual ou superior a 80 anos OR: 2,36 (1,62 - 3,43) e uso concomitante de 5 ou mais medicamentos OR: 4,74 (3,47 - 6,45). A glibenclamida foi o MPI mais prescrito para os idosos (36,6%), seguido do clonazepam (22,7%) e do ácido acetilsalicílico (10,2%). Assim, faz-se necessária a revisão periódica das listas de medicamentos padronizados, nessas unidades assistenciais, considerando o consenso brasileiro de medicamentos potencialmente inapropriados para os idosos, bem como investigações sistemáticas, a fim de detectar precocemente e evitar a ocorrência de prescrição de MPI nos grupos de maior vulnerabilidade para que se possa melhorar a qualidade da assistência ofertada.

The objective of the present study was to determine the profile of medications prescribed for elderly patients in primary care, seeking the occurrence of Potentially Inappropriate Medications (MPI), according to Beers' criteria and associated factors. The method consisted of a retrospective observational study from September to October in 2015 whose inclusion criteria were prescriptions of continuous medication for patients aged 60 years or older. The prescriptions of 820 patients were analyzed. The presence of MPI occurred in 35.4% of the prescriptions. These had the highest occurrence for the female gender OR: 1.33 (0.97 -1.80), patients aged 80 years and over OR: 2.36 (1.62 - 3.43) and concomitant use of 5 or more drugs OR: 4.74 (3.47-6.45). Glibenclamide was the most prescribed MPI for the elderly (36.6%), followed by clonazepam (22.7%) and acetylsalicylic acid (10.2%) of the prescriptions. Thus, it is necessary to periodically review the lists of standardized drugs in these assistential units, considering the Brazilian consensus on the list of inappropriate drugs for the elderly. As well as systematic investigations, in order to detect early and to prevent the occurrence of MPI prescription in the groups of greater vulnerability so that the quality of the offered assistance can be improved.

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.

Prevalence and impact of potentially inappropriate medication on community-dwelling older adults / Prevalencia e impacto de la medicación potencialmente inapropiada en ancianos que viven en comunidad

Abstract | Introduction: Potentially inappropriate medication is associated with adverse health and functional outcomes, as well as increased health care costs. Objective: To estimate the prevalence and types of potentially inappropriate medication according to the Beers criteria in community-dwelling older persons and to identify the major clinical and functional consequences of potentially inappropriate medication during two years of following. Materials and methods: We conducted a longitudinal, descriptive, and observational study that included 400 65-year or older community-dwelling people (48% women) selected by simple random sampling in 2012. In 2014, 372 people were re-evaluated and classified into two groups based on the presence or absence of potentially inappropriate medication through the follow-up period. Results: In total, 31% had polypharmacy (5-9 medications) and 1,8% had excessive polypharmacy (10 or more medications). The mean of the number of medications was higher in the potentially inappropriate medication group (3 vs. 5.78; p<0.001) and 21.9% still had the potentially inappropriate medication status during the follow-up; of them, 75% had one potentially inappropriate medication and 23% two. The presence of potentially inappropriate medication was more frequent among frail and depressed male individuals with a bad health self-assessment and comorbidities, especially diabetes mellitus and chronic obstructive pulmonary disease. In the group with sustained potentially inappropriate medication, we found a worsening health self-assessment, increased frailty, a higher incidence of recurrent falls and prevalence of depression, as well as a higher hospital admission rate, ambulatory medical consultation, and more prescribed medications. We did not find an impact on functional capacity. Conclusions: We validated the negative effects of potentially inappropriate medication in the long run for the health of older people and, therefore, potentially inappropriate medications should be monitored in primary care services to avoid greater risks.

Resumen | Introducción. La medicación potencialmente inapropiada se asocia con consecuencias clínicas, geriátricas, funcionales y farmacoeconómicas negativas. Objetivo. Estimar la prevalencia y los tipos de medicación potencialmente inapropiada según los criterios de Beers en ancianos que viven en comunidad y determinar las principales consecuencias clínicas y funcionales a lo largo de dos años de seguimiento. Materiales y métodos. Se hizo un estudio descriptivo, observacional y longitudinal que incluyó 400 mayores de 65 años (48 % mujeres) residentes en la comunidad seleccionados mediante muestreo aleatorio simple en el 2012. En el seguimiento del 2014 se reevaluaron 372 de ellos y se clasificaron en dos grupos: quienes a lo largo de los dos años siguieron tomando medicación potencialmente inapropiada y quienes no. Resultados. El 31 % de los ancianos estaban polimedicados, (5 a 9 medicamentos) y 1,8 % polimedicados de forma excesiva (10 o más medicamentos). El promedio de consumo de medicamentos era mayor en el grupo de medicación potencialmente inapropiada (3 Vs. 5,78; p<0,001), y el 21,9 % siguieron recibiendo medicación poitencialmente inapropiada durante el seguimiento; de ellos, el 75 % recibía un medicamento de este tipo y el 23 %, dos. El uso de dicha medicación fue más frecuente en hombres frágiles con una mala percepción de la propia salud, depresión y un mayor número de comorbilidades, especialmente diabetes mellitus y enfermedad-pulmonar-obstructiva-crónica. En el grupo que siguió recibiendo medicación potencialmente inapropiada la percepción de la propia salud empeoró, con un incremento de la fragilidad, las caídas recurrentes y la depresión, así como en los ingresos hospitalarios y las consultas médicas y mayor cantidad de medicamentos formulados. No se evidenció un impacto en la capacidad funcional. Conclusiones. Se corroboran los efectos negativos a largo plazo de la medicación potencialmente inapropiada en la salud de los ancianos, por lo cual se la debe monitorizar en la atención primaria para evitar mayores riesgos.

Nurse knowledge about potentially inappropriate medications for elderly

Due to the consequences of changes in fertility and mortality rates, there is an increase in population aging. In this context, the use of potentially inappropriate medications in this population makes nurses important agents in the identification of adverse reactions, requiring their knowledge about these drugs and their effects. The study aimed to verify nurses knowledge about the 2015 AGS BeersCriteria, regarding the potentially inappropriate medications for the elderly, and their adverse effects. It is a cross-sectional, descriptive, and analytical study with a quantitative and qualitative approach performed in a teaching hospital in the Triângulo Mineiro, Minas Gerais. Of the 80 professionals, 74.1% reported attending the elderly frequently, and only 3.8% had a specialization course in elderly health. Only 13.8% reported knowing the Beers Criteria. And 69% believe that adverse drug reactions can be confused as a new symptom and because of this, new drugs can be inserted into the therapeutic plan. Three categories emerged: The importance of assertive knowledge about PIMs, The nurse as a fundamental character in ADR, and Knowledge as a reinforcer of care. There is evidence of the need to train nurses to better identify adverse drug reactions so that they can act on these events avoiding the worsening of the individual.

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.

Análise do perfil e da frequência de erros de dispensação de medicamentos em um hospital de médio porte nos anos de 2009 a 2019 / Analysis of the profile and frequency of medication dispensing errors in a medium-sized hospital in the years 2009 to 2019

Objetivo: avaliar o perfil e a frequência de erros de dispensação de medicamentos entre os anos de 2009 e 2019 em um hospital de médio porte. Métodos: neste trabalho descritivo documental de abordagem quantitativa, os medicamentos envolvidos em erros de dispensação foram classificados de acordo com Anatomical Therapeutic Chemical (ATC) e medicamentos potencialmente perigosos. E os erros foram categorizados segundo guia da Política Nacional de Segurança do Paciente (PNSP). Resultados: os resultados demonstraram que os erros aumentaram no decorrer dos anos, apresentando 28 erros/mês no primeiro ano e 58,6 erros/mês no último, e que os tipos de erros mais frequentes são de omissão do envio (n=1532; 39,0%) e dispensação com dose ou quantidade errada (n=827; 21,0%). A classe de medicamento prescrita mais envolvida em erros foi a de agentes anti-infecciosos de uso sistêmico (n=806; 20,5%). Entre os medicamentos potencialmente perigosos, os de ação no sistema nervoso (n=271; 32,8%) foram os mais dispensados de forma errada, tendo, também, como principal tipo de erro, a omissão, e seu principal representante foi o diazepam (n=84; 31,0%). Conclusões: a quantidade de erros de dispensação (mais de um por dia, em média) evidencia a importância do profissional farmacêutico como potencializador para transformar esse cenário, tanto no âmbito gerencial ao propor barreiras de segurança, quanto clínico, ao acompanhar o processo de uso dos medicamentos.

Objetctive: to evaluate the profile and frequency of medication dispensing errors between the years of 2009 to 2019 in a medium-sized hospital. Methods: In this descriptive documentary work of quantitative approach, the drugs involved in dispensing errors were classified according to the Anatomical Therapeutic Chemical (ATC) and potentially dangerous drugs. The errors were categorized according to the guidelines of the National Policy for Patient Safety (NPPS). Results: The results showed that errors increased over the years, presenting 28 errors/month in the first year and 58.6 errors/month in the last, and that the most frequent types of errors are shipment omission (n = 1532; 39.0%) and dispensing with wrong dose or amount (n = 827; 21.0%). The medication class prescribed most involved in errors was anti-infective agents for systemic use (n = 806; 20.5%). Among the potentially dangerous drugs, those with action on the nervous system (n = 271; 32.8%) were the most misdispensed, also having omission as the main type of error, and its main representative was diazepam (n = 84; 31.0%). Conclusions: The amount of dispensing errors (more than one per day, on average) highlights the importance of the professional pharmacist as a potential generator to transform this scenario, both managerially, by proposing safety barriers, and clinically, by monitoring the process of medication use.

Potential prescribing omissions according to START criteria at the time of hospital discharge

The purpose of this study is to describe the frequency of potential drug prescribing omissions (PPOs) for elderly patients at the time of hospital discharge and to compare the frequency PPOs among different medical specialities. This cross-sectional study examined data from elderly patients when they were admitted for >24 h to a northeastern Brazil teaching hospital during June-December 2016. Were included in the study 227 patients, of whom 36.9% had at least one PPO. The highest number of PPOs was identified among those with at least 5 prescribed drugs. In total, 153 PPOs were identified at hospital discharge. In most cases (78.4%), patients were not evaluated by the specialist physician.The most commonly identified PPOs on discharge were: the omission of statin therapy in cases of diabetes mellitus plus one or more cardiovascular-associated factor; calcium and vitamin D supplements in patients with known osteoporosis; and angiotensin converting enzyme inhibitors in cases of chronic heart failure. The results of this study suggest that the frequency of prescribing omissions PPOs during patient discharge was high. This can be avoided by the careful evaluation by prescribers with experience in certain specialties where several prescribed omissions would be common.

Medicamentos potecialmente inapropriados para idosos: da seleção à prescrição na atenção primária à saúde / Potentially inappropriate medications for the elderly: from selection to prescription in primary health care

O envelhecimento populacional é uma realidade crescente e os idosos apresentam a necessidade de utilização de medicamentos, muitas vezes expondo-os a riscos. Os medicamentos potencialmente inapropriados (MPI) para idosos são aqueles em que os riscos superam os benefícios. Os medicamentos essenciais devem atender as necessidades prioritárias de saúde de uma população e a prescrição de medicamentos é considerada um dos aspectos determinantes para o uso. O objetivo do estudo foi analisar os medicamentos potencialmente inapropriados para idosos, desde a seleção de medicamentos essenciais à prescrição na Atenção Primária à Saúde (APS). Foi realizado um estudo descritivo e analítico com abordagem qualitativa e quantitativa, de março a dezembro de 2019, na APS em Campina Grande, PB. A pesquisa foi desenvolvida através da triangulação de métodos: 1) pesquisa documental, que analisou os medicamentos das Relação Nacional de Medicamentos Essenciais (RENAME nas edições 2010 e 2020 de acordo com as listas AGS/Beers e as Listas de Medicamentos Essenciais (LME) da Organização Mundial de Saúde vigentes à época; 2) estudo transversal, realizado através de entrevistas com 458 idosos usuários de 71 unidades básicas de saúde. As variáveis independentes abrangeram características demográficas e socioeconômicas, condição de saúde e utilização de medicamentos e a variável dependente foi o medicamento prescrito ser classificado como inapropriado pelo Consenso Brasileiro de Medicamentos Potencialmente Inapropriado. Foi feita análise descritiva dos dados e regressão de Poisson; e, 3) estudo de caso, realizado através de entrevistas com 10 prescritores da APS para conhecer a percepção desses profissionais sobre a prática prescritiva para idosos. Foram prescritos 1449 medicamentos e 244 MPI (16,8%), dos quais 91,6% e 70,5% estavam elencados na RENAME, respectivamente. A maioria dos MPI atuavam no Sistema Nervoso Central (54,4%) e trato alimentar e metabolismo (20,1%). Entre os principais MPI, observou-se ausência de alternativas terapêuticas mais seguras disponíveis na RENAME. No estudo transversal, identificou-se uma prevalência de prescrição de pelo menos um MPI em 44,8% (IC95% 40,2-49,3) dos idosos. 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 ao uso de MPI e autorreferir ser portador de hipertensão arterial sistêmica tornou-se fator de proteção (RP=0,65; IC95% 0,49-0,87). Na análise qualitativa, emergiram duas categorias: 1) Abordagem dos prescritores no atendimento aos idosos na APS; e, 2) Uso de medicamentos por idosos: o olhar dos prescritores. Os médicos relataram promover atividades de prevenção, porém enfatizaram o tratamento das doenças crônicas prevalentes entre idosos. Também destacaram a polifarmácia e consideraram inadequada a utilização de benzodiazepínicos. Constatou-se desconhecimento dos médicos sobre as listas de medicamentos inapropriados. A medicalização dos idosos e a disponibilidade de medicamentos essenciais foram descritos como desafios. O estudo identificou uma alta ocorrência de prescrição de medicamentos potencialmente inapropriados para idosos na Atenção Primária à Saúde em conformidade com a lista nacional de medicamentos essenciais e escassez de alternativas terapêuticas mais seguras para idosos. Evidencia-se necessidade de ações que busquem qualificar o acesso a medicamentos por idosos como a elaboração de uma lista de medicamentos específica ou a inserção de alternativas terapêuticas mais seguras para idosos na RENAME, juntamente com a capacitação dos profissionais prescritores e o acompanhamento dos idosos. Diante do envelhecimento da população brasileira, faz-se pertinente garantir acesso a medicamentos aliado à segurança dos idosos (AU).

Population aging is a growing reality, and the elderly need medications, which often expose them to risks. Potentially inappropriate medications (PIMs) in the elderly are those in which risks outweigh benefits. Essential medications must meet health needs of a population, and medication prescription is one determinant for its use. This study aimed to analyze PIM in the elderly from the selection of essential drugs to prescription in primary health care (PHC). A descriptive and analytical study with quali-quantitative approach was conducted in PHC in Campina Grande (PB) between March and December 2019. The study was developed triangulating methods: 1) documentary research, which analyzed medicines of the National Essential Medicines List (RENAME) in 2010 and 2020 editions according to AGS/Beers criteria and essential medicines lists (EML) of the World Health Organization; 2) crosssectional study, conducted using interviews with 458 elderly users of 71 basic health units. Independent variables were demographic and socioeconomic characteristics, health condition, and use of medication, whereas the dependent variable was prescribed medication classified as inappropriate by the Brazilian Consensus on Potentially Inappropriate Medications. Descriptive data analysis and Poisson regression were performed; and 3) case study, using interviews conducted with 10 PHC prescribers to observe perception of these professionals regarding prescription for the elderly. One thousand four hundred and forty-nine medications and 244 PIM (16.8%) were prescribed; of these, 91.6% and 70.5% were listed in RENAME, respectively. Most PIM acted in the central nervous system (54.4%) and gastrointestinal tract and metabolism (20.1%). RENAME lacked safer therapeutic alternatives for main PIMs. In the cross-sectional study, at least one PIM was prescribed for 44.8% (95%CI 40.2 ˗ 49.3) of the elderly. In the adjusted model, depression (PR=2.01; 95%CI 1.59 ˗ 2.55), use of medication other than those prescribed (PR=1.36; 95%CI 1.08 ˗ 1.72), and polypharmacy (PR = 1.80; 95%CI 1.40 ˗ 2.33) were associated with PIM, whereas self-reported hypertension was a protective factor (PR=0.65; 95%CI 0.49 ˗ 0.87). Two categories emerged in the qualitative analysis: 1) approach of prescribers to assist the elderly in PHC and 2) use of medication by the elderly: view of prescribers. Doctors reported preventive activities but emphasized treatment of prevalent chronic diseases among the elderly. They also highlighted polypharmacy and considered benzodiazepines to be inappropriate. Doctors lacked knowledge about inappropriate medication lists. Medicalization of the elderly and availability of essential medication were described as challenges. PIMs were highly prescribed for the elderly in PHC according to the RENAME and safer therapeutic alternatives were absent. Actions to qualify access of the elderly to medication are needed, such as elaborating a specific list of medication, inserting safer therapeutic alternatives for the elderly in RENAME, training prescribers, and monitoring the elderly. Access to medication and safety of the elderly must be guaranteed because of aging of the Brazilian population (AU).

Criterios STOPP-START y la prescripción inapropiada del anciano / STOPP/START criteria and inappropriate prescription in the elderly

Introducción: El envejecimiento no solo promueve daños moleculares y celulares con deterioro progresivo de las funciones del cuerpo, sino que este proceso trasciende a los tratamientos y predispone a las prescripciones potencialmente inapropiadas y a la polifarmacia. Esta situación complejiza la atención del anciano con mayor utilización de servicios sanitarios y gastos en medicamentos. Objetivo: Identificar posibles prescripciones potencialmente inapropiadas y estimar la influencia de factores biomédicos en la polifarmacia de los ancianos hospitalizados. Material y Métodos: Investigación cuasi-experimental estudio antes-después, que acopió información de variables biomédicas de las historias clínicas de 200 pacientes hospitalizados en el Centro de Investigaciones sobre Longevidad, Envejecimiento y Salud, se utilizaron los criterios STOPP-START para identificar prescripciones potencialmente inapropiadas; se realizaron pruebas para estadística descriptiva e inferencial (α=0,05). Resultados: Se identificaron al ingreso 349 prescripciones inapropiadas STOPP y 357 prescripciones inapropiadas START, la sección correspondiente al sistema nervioso central aportó el 24,8 por ciento de las prescripciones inapropiadas STOPP y el sistema cardiovascular reveló el 59,9 por ciento de las prescripciones inapropiadas START. La polifarmacia estuvo presente en el 43,0 por ciento de los ancianos y la comorbilidad fue la variable que mostró mayor fuerza de asociación con la polifarmacia (OR =8,65; IC-95 por ciento: 4,51-16,59), seguido por la presencia de dos o más prescripciones inapropiadas según los criterios STOPP. Conclusiones: Los criterios STOPP-START identifican prescripciones inapropiadas en el contexto sanitario cubano, todo lo cual impacta de forma negativa en la polifarmacia de los ancianos. El sistema nervioso central y el sistema cardiovascular mostraron el mayor número de prescripciones potencialmente inapropiadas(AU)

Introduction: Aging not only promotes molecular and cellular damage with progressive deterioration of body functions, but this process transcends treatments and predisposes to potentially inappropriate prescriptions and polypharmacy. This situation complicates the care of the elderly with greater use of health services and drug expenses. Objective: To identify possible potentially inappropriate prescriptions and estimate the influence of biomedical factors on polypharmacy in hospitalized elderly people. Material and Methods: Quasi-experimental before-after study which collected information on biomedical variables from the medical records of 200 hospitalized patients at the Longevity, Aging and Health Research Center. The STOPP/START criteria were used to identify potentially inappropriate prescriptions. Descriptive and inferential statistical tests were performed (α = 0.05). Results: A total of 349 inappropriate STOPP prescriptions and 357 inappropriate START prescriptions were identified upon admission. The section corresponding to the central nervous system contributed 24.8 percent of the inappropriate STOPP prescriptions and the cardiovascular system revealed 59.9 percent of the inappropriate START prescriptions. Polypharmacy was present in 43.0 percent of the elderly and comorbidity was the variable that showed the greatest strength of association with polypharmacy (OR = 8.65; 95 percent CI: 4.51-16.59), followed by the presence of two or more inappropriate prescriptions according to the STOPP criteria. Conclusions: The STOPP/START criteria identify inappropriate prescriptions in the Cuban healthcare context which has a negative impact on polypharmacy in the elderly. The central nervous system and the cardiovascular system showed the highest number of potentially inappropriate prescriptions(AU)

Cloroquina e hidroxicloroquina: medicamentos potencialmente inapropriados a idosos? / Chloroquine and hydroxychloroquine: potentially inappropriate medications for older adults?

INTRODUÇÃO: Medicamentos potencialmente inapropriados a idosos (MPII) provocam mais efeitos adversos do que benefícios. Os critérios de Beers (CB) da American Geriatrics Society 2019 (CB2019) consideraram cinco situações clínicas como MPII. A análise de medicamentos por essas situações pode auxiliar na prescrição a idosos? Procurando exemplo prático dessa questão, optou-se por análise de fármacos atualmente questionados quanto ao seu uso seguro em idosos. OBJETIVO: Verificar se cloroquina e hidroxicloroquina se enquadram como MPII e se essa análise é aplicável clinicamente. METODOLOGIA: Sistematizou-se o objetivo pelas cinco situações clínicas definidas como MPII pelos CB2019. RESULTADOS: Ambos os fármacos preenchem respectivamente quatro (cloroquina) e cinco (hidroxicloroquina) dessas situações clínicas. Esta análise permitiu a provável definição de MPII para esses medicamentos de forma simples, por intermédio de breve análise de literatura acessível. CONCLUSÃO: Cloroquina e hidroxicloroquina podem ser considerados MPII. Espera-se replicar essa análise para outros medicamentos e reduzir iatrogenias em idosos.

INTRODUCTION: Potentially inappropriate medications (PIMs) for older adults cause more adverse effects than benefits. The 2019 American Geriatrics Society Beers Criteria (2019BC) considered five clinical situations as PIM use in older adults. Can drug analysis, according to these situations, assist in the act of making prescriptions for older people? Seeking a practical example for this question, we assessed drugs currently questioned as to their safe use among older people. OBJECTIVE: To check if chloroquine and hydroxychloroquine fit the PIM criteria for older adults and whether this analysis is clinically applicable. METHODS: We systematized the objective based on the five clinical situations defined as PIM use in older adults by the 2019BC. RESULTS: Chloroquine and hydroxychloroquine fulfill, respectively, four and five of these clinical situations. This evaluation allowed the likely definition of these drugs as PIMs for older adults in a simple way, based on a brief analysis of the available literature. CONCLUSION: Chloroquine and hydroxychloroquine may be considered PIMs for older adults. We expect that this analysis can be replicated with other drugs and reduce iatrogenesis in older people.
