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.

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.

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.

Evidence of association between the use of drugs and community-dwelling older people frailty: a cross-sectional study

ABSTRACT BACKGROUND: The scientific literature has shown that an association between polypharmacy and frailty exists. However, few studies have also considered drug interactions and the use of potentially inappropriate medications. OBJECTIVE: To evaluate the association between the use of drugs and frailty among community-dwelling older people. DESIGN AND SETTING: Cross-sectional study carried out among 580 older people in Uberaba (MG). METHODS: Data were collected at these older people's homes using instruments validated in Brazil. Descriptive, bivariate and binary logistic regression analyses were performed (P < 0.05). RESULTS: Most of these individuals were classified as pre-frail (55.7%), while 13.1% were frail. It was found that 31.7% of them presented polypharmacy, 41.7% had drug interactions and 43.8% were using potentially inappropriate medications. In the initial model, polypharmacy (odds ratio, OR = 1.91; confidence interval, CI = 1.27-2.86) and use of potentially inappropriate medications (OR = 2.45; CI = 1.68-3.57) increased the chance that these older people would be pre-frail or frail. In the final adjusted model, use of potentially inappropriate drugs remained associated with the outcome (OR = 2.26; CI = 1.43-3.57). CONCLUSION: Use of potentially inappropriate medications was the independent variable that explained the occurrence of frailty in a representative sample of community-dwelling older adults.

Prevalência do uso de medicamentos potencialmente inapropriados ao idoso no Brasil: uma revisão sistemática / Prevalencia del uso de medicamentos potencialmente inapropiados para los ancianos en Brasil: una revisión sistemática / Prevalence use of potentially inappropriate drugs for elderly in Brazil: a sistematic review

O envelhecimento está relacionado, via de regra, ao uso de medicamentos. Esta é uma revisão sistemática sobre as prevalências de uso de medicamento potencialmente perigosos em idosos, em estudos brasileiros, utilizando-se o Critério de Beers. A prevalência variou entre 17 e 98,2% em amostras domiciliares, ambulatoriais, hospitalares e em instituições de longa permanência. Dados que demonstram a necessidade de políticas de enfrentamento aos riscos inerentes ao uso de medicamento pelo paciente idoso no Brasil.

The aging is related with use of drugs. This research is a systematic review about use of potentially inappropriate drugs for elderly evaluated by Beers Criteria. The prevalence's range was 17 to 98,2% on home, ambulatory, hospital or nursing home samples. These data demonstrate that governmental politics are necessary to face the risks of drugs using by elderly in Brazil.

Identificação do uso e fatores associados ao consumo de medicamentos potencialmente inapropriados por idosas / Identification of the use and associated factors with the consumption of potentially inappropriate medications by elderly women

Este estudo objetiva identificar o uso de medicamentos potencialmente inapropriados por idosas e os fatores associados. Realizou-se delineamento transversal, retrospectivo e analítico. A amostra foi constituída por mulheres, com idade igual ou superior a 60 anos, em uso de no mínimo um medicamento. Para a definição e identificação dos medicamentos potencialmente inapropriados, foram empregados os critérios de Beers. Participaram do estudo 79 idosas, com idade média de 63,44 ± 2,39 anos, as quais utilizavam um total de 225 medicamentos, dos quais 72 (35,1%) foram classificados como medicamentos potencialmente inapropriados, utilizados por 44 (55,7%) mulheres. O número de medicamentos em uso e o relato de insônia e depressão apresentaram-se associados ao uso de medicamentos inapropriados. Os inibidores da bomba de prótons, benzodiazepínicos e anti-inflamatórios não esteroides foram as classes de medicamentos inapropriados mais frequentes. Os resultados evidenciam que mais da metade das idosas estão em uso de no mínimo um medicamento inapropriado. Nesse contexto, destaca-se a necessidade da divulgação dos critérios de Beers entre os profissionais de saúde como estratégia para a promoção da farmacoterapia segura e eficaz à população idosa.

This study's objective is to identify the use of potentially inappropriate medications by elderly women and associated factors. 125Estud. interdiscipl. envelhec., Porto Alegre, v. 23, n. 3, p. 111-128, 2018. A R T I G O S A cross-sectional retrospective and analytical design was carried out. The sample consisted of women aged over 60 years in use of at least one medication. For definition and identification of potentially inappropriate medications, the Beers criteria were used. The study included 79 elderly women, whose mean age was 63.44 ± 2.39 years and whom used a total of 225 medications, of which 72 (35.1%) were classified as potentially inappropriate medications, used by 44 (55.7%) women. The number of medications in use, the reporting of insomnia and depression were associated to the use of inappropriate medications. Proton pump inhibitors, benzodiazepines, and non-steroidal anti- -inflammatory drugs were the most common classes of inappropriate medications. The results evidenced that more than half of the elderly women are using at least one inappropriate medication. In this context, it's important to bring to attention the need to disseminate the Beers criteria among health professionals as a strategy for the promotion of safe and effective pharmacotherapy to the elderly population.

Uso inapropiado de medicamentos en adultos mayores: resultados de la Encuesta Nacional de Salud 2010 / Inappropriate medication use among Chilean older people

Background: Inappropriate medication use in older people is an important source of adverse events and complications. Aim: To determine the frequency of inappropriate medication use in the general population. Material and Methods: As part of the 2010 Chilean National Health Survey, 1,048 persons aged 65 years or more were interviewed about medication use. The information obtained was analyzed using standardized Beer’s criteria, adapted for the Chilean population, to define inappropriate medication use. A logistic regression model was performed to define risk factors for inappropriate medication use. Results: Ten percent of subjects had a high risk of inappropriate medication use. The most common medications used were chlorphenamine, amitriptyline, diazepam, chlorpromazine, chlordiazepoxide and piroxicam. The risk factors detected were female gender, polypharmacy and a bad health self-perception. Conclusions: Inappropriate medication use is common among Chilean older people and should be discouraged.

Potentially inappropriate medication use in institutionalized older adults according to the Beers Criteria

The need for specific care, coupled with new family arrangements, has contributed to the increasing institutionalization of elderly members. The purpose of this study was to evaluate drug use by institutionalized older adults according to Beers Criteria. This prospective, longitudinal study was conducted in the three non-profit long-stay geriatric care institutions of Campo Grande, in the Central-West region of Brazil. All subjects aged 60 years and above on November 2011 were included and followed until November 2012. Eighteen subjects were excluded and the final sample consisted of 133 individuals aged 60 to 113 years. Overall, 212 medications were used at geriatric care institution A, 532 at B, and 1329 at C. Thirty-four drugs were inappropriately prescribed 89 times at geriatric care institution A (41.98%), 49 prescribed 177 times at B (33.27%), and 91 prescribed 461 times at C (34.68%). Statistical differences in the inappropriate drug use were found between genders (p=0.007). The most commonly used potentially inappropriate medication were first-generation antihistamines (15.34%). There was a high frequency in the use of potentially inappropriate medications which can initiate marked side effects and may compromise the fragile health of institutionalized elderly. Thus, adopting the Beers Criteria in prescribing medication contributes to minimize adverse reactions and drug interactions.

A exigência de cuidados específicos, aliada aos novos arranjos familiares, tem contribuído para a crescente institucionalização dos idosos. O objetivo do presente trabalho foi avaliar o uso de medicamentos por idosos institucionalizados utilizando os Critérios de Beers. Este estudo longitudinal prospectivo foi realizado nas três instituições de longa permanência para idosos de Campo Grande, Centro-Oeste do Brasil. Todos os sujeitos com 60 anos ou mais foram incluídos em Novembro de 2011 e acompanhados até Novembro de 2012. Dezoito idosos foram excluídos, sendo a amostra final composta por 133 sujeitos com idade entre 60 e 113 anos. O total de medicamentos utilizados foi 212 na instituição A, 532 na B e 1329 na C. Foram identificados 34 medicamentos inapropriados, prescritos 89 vezes na instituição A (41.98%), 49 prescritos 177 vezes na B (67.29%) e 90 prescritos 460 vezes na C (34.61%). Este estudo demonstrou diferença estatística na utilização de medicamentos inapropriados entre os gêneros (p=0.007). Os anti-histamínicos de 1ª geração foram os medicamentos potencialmente inapropriados para idosos mais utilizados (15.34%). Houve elevada frequência no uso de MPI, os quais podem desencadear efeitos colaterais acentuados e comprometer mais a saúde fragilizada do idoso institucionalizado. Ainda, a adoção dos Critérios de Beers na prescrição contribui para minimizar as reações adversas e interações medicamentosas.
