RESUMO

Introduction: Medications are a fundamental part of the treatment of multiple pathologies. However, despite their benefits, some are considered potentially inappropriate medications for older people given their safety profile. Epidemiological data differences related to potentially inappropriate medications make it difficult to determine their effects on elderly people. Objective: To estimate the prevalence and types of potentially inappropriate medications using the 2019 Beers Criteria® in a cohort of adults older than 65 years. Materials and methods: We performed an observational, multicenter, retrospective, longitudinal study of a four-year follow-up of potentially inappropriate medications in community-dwelling older adults. Results: We followed 820 participants from five cities for four years (2012-2016) and evaluated them in three different moments (m1 = 2012, m2 = 2014, and m3 = 2016). The average age was 69.07 years, and 50.9% were women. The potentially inappropriate medication prevalence in the participants was 40.24%. The potentially inappropriate medications' mean among the studied subjects in the first moment was 1.65 (SD = 0.963), in the second was 1.73 (SD = 1.032), and in the third was 1.62 (SD = 0.915). There were no statistical differences between measurements (Friedman test, value = 0.204). The most frequent potentially inappropriate medications categories were gastrointestinal (39.4%), analgesics (18.8%), delirium-related drugs (15.4%), benzodiazepines (15.2%), and cardiovascular (14.2%). Conclusions: About half of the population of the community-dwelling older adults had prescriptions of potentially inappropriate medications in a sustained manner and without significant variability over time. Mainly potentially inappropriate medications were gastrointestinal and cardiovascular drugs, analgesics, delirium-related drugs, and benzodiazepines.

Las diferencias en los datos epidemiológicos relacionados con los medicamentos potencialmente inapropiados dificultan el establecimiento de sus efectos en adultos mayores. Objetivo. Estimar la prevalencia longitudinal y los tipos de medicamentos potencialmente inapropiados, utilizando los criterios Beers® del 2019 en una cohorte de adultos mayores de 65 años. Materiales y métodos. Se realizó un estudio observacional, multicéntrico, retrospectivo y longitudinal, de cuatro años de seguimiento de los medicamentos potencialmente inapropiados en adultos mayores de la comunidad. Resultados. Se evaluaron 820 participantes de cinco ciudades durante cuatro años (2012 a 2016) en tres momentos (m1: 2012, m2: 2014 y m3; 2016). La edad promedio fue de 69,07 años y el 50,9 % eran mujeres. La prevalencia de medicamentos potencialmente inapropiados en los participantes fue del 40,24 %. El promedio de estos medicamentos entre los sujetos estudiados en el primer momento fue de 1,65 (DE = 0,963), en el segundo fue de 1,73 (DE = 1,032) y en el tercero fue de 1,62 (DE = 0,915). No hubo diferencias estadísticas entre las mediciones (prueba de Friedman, p = 0,204). Las categorías de los medicamentos potencialmente inapropiados más frecuentes fueron: gastrointestinales (39,4 %), analgésicos (18,8 %), relacionados con delirium (15,4 %), benzodiacepinas (15,2 %) y cardiovasculares (14,2 %). Conclusiones. En cerca de la mitad de la población de adultos mayores de la comunidad, se prescribieron medicamentos potencialmente inapropiados de manera sostenida y sin variabilidad importante en el tiempo. Los más recetados fueron aquellos para tratar malestares gastrointestinales y cardiovasculares, analgésicos, para el delirium y benzodiacepinas.

RESUMO

OBJECTIVE: Investigate the association between potentially inappropriate medication (PIM) use and the risk of death among community-dwelling older Brazilian adults. METHODS: Participants from the Health, Well-Being, and Aging Cohort Study (SABE) in São Paulo, Brazil, between 2000 and 2016 were included. The dependent variable was all-cause mortality, measured as the time elapsed until death. The exposure of interest was the use of PIM according to the Beers Criteria 2019 version. All covariates, except for sex and education, were considered time-varying. RESULTS: PIM use was not associated with mortality after adjusting for covariates (HR = 0.99; 95 % CI: 0.88-1.12). There was a significant interaction between PIM use and age (HR = 0.98; 95 % CI: 0.96-0.99). CONCLUSION: The association between PIM use and the risk of death was moderated by age. Future studies should consider the impact of necessary medication omissions when assessing the mortality risk associated with PIM use.

RESUMO

INTRODUCTION: Older patients are more susceptible to medication use, and physiological changes resulting from aging and organic dysfunctions presented by critically ill patients may alter the pharmacokinetic or pharmacodynamic behavior. Thus, critically ill older people present greater vulnerability to the occurrence of pharmacotherapeutic problems. OBJECTIVE: To evaluate pharmacotherapy and the development of potential adverse drug reactions (ADRs) in older patients admitted to an intensive care unit (ICU). METHOD: A cohort study was conducted in an ICU for adults of a Brazilian University Hospital during a 12-month period. The patients' pharmacotherapy was evaluated daily, considering the occurrence of ADRs and drug-drug interactions (DDIs), the use of potentially inappropriate medications (PIMs) for older people, and the pharmacotherapy anticholinergic burden (ACB). A trigger tool was used for active search of ADRs, with subsequent causality evaluation. PIM use was evaluated by means of the Beers criteria and the STOPP/START criteria. The ABC scale was employed to estimate ACB. The Micromedex® and Drugs.com® medication databases were employed to evaluate the DDIs. RESULTS: The sample of this study consisted of 41 patients, with a mean age of 66.8 years old (±5.2). The 22 triggers used assisted in identifying 15 potential ADRs, and 26.8% of the patients developed them. The mean estimated ACB score was 3.0 (±1.8), and the patients used 3.1 (±1.4) and 3.3 (±1.6) PIMs according to the Beers and the STOPP criteria, respectively. A total of 672 DDIs were identified, with a mean of 16.8 (±9.5) DDIs/patient during ICU hospitalization. Our findings show an association between occurrence of ADRs in the ICU and polypharmacy (p=.03) and DDIs (p=.007), corroborating efforts for rational medication use as a preventive strategy. CONCLUSIONS: Using tools to evaluate the pharmacotherapy for older people in intensive care can assist in the recognition and prevention of pharmacotherapeutic problems, with emphasis on the identification of ADRs through the observation of triggers and subsequent causality analysis.

RESUMO

Abstract: This study is a systematic literature review of the association between lists of potentially inappropriate medications (PIM) in clinical practice and health outcomes of older adults followed up in primary health care. For this purpose, the PRISMA protocol was used to systematize the search for articles in the PubMed, Web of Science, Scopus, Cochrane Central, LIVIVO and LILACS databases, in addition to the gray literature. Studies with randomized clinical trials were selected, using explicit criteria (lists) for the identification and management of PIM in prescriptions of older patients in primary care. Of the 2,400 articles found, six were used for data extraction. The interventions resulted in significant reductions in the number of PIM and adverse drug events and, consequently, in potentially inappropriate prescriptions (PIP) in polymedicated older adults. However, there were no significant effects of the interventions on negative clinical outcomes, such as emergency room visits, hospitalizations and death, or on improving the health status of the older adults. The use of PIM lists promotes adequate medication prescriptions for older adults in primary health care, but further studies are needed to determine the impact of reducing PIM on primary clinical outcomes.

Resumo: Este estudo revisou sistematicamente a literatura sobre a associação de listas de medicamentos potencialmente inapropriados (MPI) na prática clínica e desfechos de saúde na população idosa acompanhada na atenção primária à saúde. Para tanto, o protocolo PRISMA foi usado para sistematizar a busca de artigos nas bases de dados PubMed, Web of Science, Scopus, Cochrane Central, LIVIVO e LILACS, além da literatura cinzenta. Foram selecionados estudos com ensaios clínicos randomizados, incluindo a utilização de critérios explícitos (listas) para identificar e manejar MPI em prescrições para idosos atendidos na atenção primária. Dos 2.400 artigos encontrados, seis foram utilizados para extração de dados. As intervenções reduziram significativamente o número de MPI e eventos adversos a medicamentos e, consequentemente, nas prescrições potencialmente inadequadas em idosos polimedicados. No entanto, não houve efeitos significativos das intervenções sobre desfechos clínicos negativos (como visitas a serviços de emergência, hospitalizações e óbito) ou melhora das condições de saúde dos idosos. O uso de listas de MPI pode promover a adequação da prescrição de medicamentos para idosos na atenção primária à saúde, mas mais estudos são necessários para determinar os impactos da redução de MPI em desfechos clínicos primários.

Resumen: Este estudio realizó una revisión sistemática en la literatura sobre la asociación de listas de medicamentos potencialmente inapropiados (MPI) en la práctica clínica y los resultados de salud en la población de edad avanzada monitoreada en atención primaria de salud. Para ello, se utilizó el protocolo PRISMA para sistematizar la búsqueda de artículos en las bases de datos PubMed, Web of Science, Scopus, Cochrane Central, LIVIVO y LILACS, además de la literatura gris. Se seleccionaron estudios con ensayos clínicos aleatorizados, incluyendo el uso de criterios explícitos (listas) para identificar y manejar MPI en prescripciones para adultos mayores atendidos en atención primaria. De los 2.400 artículos encontrados, seis se utilizaron para la recolección de datos. Las intervenciones tuvieron una significativa disminución en la cantidad de MPI y eventos adversos de medicamentos y, en consecuencia, en prescripciones potencialmente inapropiadas en adultos mayores polimedicados. Sin embargo, no hubo efectos significativos de las intervenciones en los resultados clínicos negativos (como consultas a servicios de urgencias, hospitalizaciones o muerte) o mejora en las condiciones de salud de los adultos mayores. El uso de listas de MPI puede promover una adecuada prescripción de medicamentos a los adultos mayores en la atención primaria de salud, si bien se necesitan más estudios para determinar los impactos de la reducción de MPI en los resultados clínicos primarios.

RESUMO

ABSTRACT BACKGROUND: The epidemiology of potentially inappropriate medications (PIMs) in critical care units remains limited, especially in terms of the factors associated with their use. OBJECTIVE: To estimate the incidence and factors associated with PIMs use in intensive care units. DESIGN AND SETTING: Historical cohort study was conducted in a high-complexity hospital in Brazil. METHODS: A retrospective chart review was conducted on 314 patients aged ≥ 60 years who were admitted to intensive care units (ICUs) at a high-complexity hospital in Brazil. The dates were extracted from a "Patient Safety Project" database. A Chi-square test, Student's t-test, and multivariable logistic regression analyses were performed to assess which factors were associated with PIMs. The statistical significance was set at 5%. RESULTS: According to Beers' criteria, 12.8% of the identified drugs were considered inappropriate for the elderly population. The incidence rate of PIMs use was 45.8%. The most frequently used PIMs were metoclopramide, insulin, antipsychotics, non-steroidal anti-inflammatory drugs, and benzodiazepines. Factors associated with PIMs use were the number of medications (odds ratio [OR] = 1.17), length of hospital stay (OR = 1.07), and excessive potential drug interactions (OR = 2.43). CONCLUSIONS: Approximately half of the older adults in ICUs received PIM. Patients taking PIMs had a longer length of stay in the ICU, higher numbers of medications, and higher numbers of potential drug interactions. In ICUs, the use of explicit methods combined with clinical judgment can contribute to the safety and quality of medication prescriptions.

RESUMO

BACKGROUND: Potentially inappropriate medication use is prevalent among older adults in primary care, leading to increased morbidity, adverse drug reactions, hospitalizations, and mortality. This study aimed to develop and validate a tool for identifying PIMs in older adults within the primary care setting. The tool is composed of a list of criteria and was created based on consensus among experts from three Spanish-speaking countries, including two from Latin America. METHODS: A literature review was conducted to identify existing tools, and prescription patterns were evaluated in a cohort of 36,111 older adults. An electronic Delphi method, consisting of two rounds, was used to reach a formal expert consensus. The panel included 18 experts from Spain, Colombia, and Argentina. The content validity index, validity of each content item, and Kappa Fleiss statistical measure were used to establish reliability. RESULTS: Round one did not yield a consensus, but a definitive consensus was reached in round two. The resulting tool consisted of a list of 5 general recommendations per disease, along with 33 criteria related to potential problems, recommendations, and alternative therapeutic options. The overall content validity of the tool was 0.87, with a Kappa value of 0.69 (95% CI 0.64-0.73; Substantial). CONCLUSIONS: The developed criteria provide a novel list that allows for a comprehensive approach to pharmacotherapy in older adults, intending to reduce inappropriate medication use, ineffective treatments, prophylactic therapies, and treatments with an unfavorable risk-benefit ratio for the given condition. Further studies are necessary to evaluate the impact of these criteria on health outcomes.

RESUMO

OBJECTIVE: To compare information on the risks of potentially inappropriate medications (PIMs) for older adults in the Beers criteria with data in the package inserts made available by the Brazilian Health Regulatory Agency. METHODS: This is an observational, cross-sectional study that compared information on the package inserts of 33 brand-name drugs in the Brazilian market with specific recommendations for older adults contemplated in the Beers criteria, categorizing them into: complete, incomplete, absent, or discrepant. RESULTS: Among the analyzed package inserts, 21.21% did not present a specific section dedicated to the use of these drugs by older adults and data were scattered throughout the text; 63.64% were classified as incomplete; 33.33% lacked data; and 3.03% had discrepant information. CONCLUSION: The analyzed package inserts presented incomplete data or lacked information characterizing the drugs as PIMs for older adults. This study demonstrated that some package inserts of drugs used in Brazil are not satisfactory, warranting higher caution in the medical community when prescribing these medications and guiding patients

OBJETIVO: Comparar as informações sobre os riscos de medicamentos potencialmente inapropriados (MPIs) para idosos contidas nos critérios Beers com as informações presentes nas bulas para profissionais de saúde disponibilizadas pela Agência Nacional de Vigilância Sanitária no Brasil. METODOLOGIA: Estudo observacional e transversal que comparou informações das bulas para profissionais de saúde de 33 medicamentos de referência no mercado brasileiro com recomendações específicas para idosos contempladas nos critérios Beers e que foram categorizadas em: completas, incompletas, ausentes ou discrepantes. RESULTADOS: Dentre as bulas dos MPIs analisadas, 21,21% não apresentam seção específica destinada ao uso desses medicamentos por idosos, nas quais as informações estão dispersas pelo texto; 63,64% delas foram classificadas como incompletas; 33,33% tinham informações ausentes; e 3,03% com informações discrepantes. CONCLUSÃO: As bulas analisadas apresentaram dados incompletos ou não apresentam qualquer informação que caracterizasse o medicamento como MPI para idosos. Este estudo demonstra que algumas bulas de medicamentos utilizados no Brasil não estão satisfatórias, sugerindo maior cautela à comunidade médica na prescrição e na orientação aos seus pacientes

RESUMO

ABSTRACT Objective: to identify the prevalence and associations of polypharmacy and potentially inappropriate medication use among older adults with hypertension treated in primary care. Methods: a cross-sectional study carried out with older adults with hypertension treated at a Family Health Strategy unit. Data collection included analysis of medical records, interviews and multidimensional assessment of older adults. Socio-demographic information and clinical variables were collected. Statistical analysis was performed by multiple logistic regression. Results: polypharmacy prevalence was 38.09%, and potentially inappropriate medication (PIM), 28.57%. There was a significant association between polypharmacy and PIM use, altered sleep and ethnicity. PIM use was associated with polypharmacy, worse family functioning, and absence of a caregiver. Cognitive decline reduces the prevalence of these medications. Conclusions: polypharmacy and PIM use among older adults with hypertension represent a problem in this population, especially among the most vulnerable.

RESUMO

Resumo Objetivos Neste estudo prospectivo, avaliamos o impacto do uso de medicamentos potencialmente inapropriados prescritos antes da internação (PIM-ph) na mortalidade de idosos. Métodos Foram incluídos 318 pacientes com idade ≥ 65 anos que procuraram atendimento de emergência e foram internados por qualquer motivo clínico. As informações sobre os indicadores clínicos e sociais foram obtidas por meio de entrevistas estruturadas, 24 a 48 horas após a internação. Os medicamentos usados por esses pacientes foram registrados e o uso de PIM-ph foi identificado pela análise brasileira baseada em consenso de uso de PIM. A análise considerou a influência de todo conjunto de PIM-ph, bem como de alguns PIM-ph específicos. O impacto do uso de PIM-ph na sobrevida de idosos hospitalizados foi determinado por meio da análise multivariada de regressão de Cox. Resultados A prevalência de PIM-ph foi 49,7% (n = 158). Um total de 85 (26,7%) pacientes faleceram durante a internação ou até 30 dias após a alta. Dezoito classes farmacológicas de uso de PIM-ph foram identificadas. O uso de PIM-ph, benzodiazepínico (IC: 1.055-3.365, p= 0.032), digoxina (IC: 1.623-7.048, p=0.001) e diuréticos de alça (IC: 1.000-3.455, p=0.05) aumentou o risco relativo de mortalidade independente de sexo, idade, causas clínicas de hospitalização, risco de fragilidade, suporte social, presença de sintomas de confusão, polifarmácia e evolução intra-hospitalar de complicações geriátricas. Conclusão O uso de PIM-ph (Benzodiazepínicos, digoxina e diuréticos de alça) pode contribuir para o risco de mortalidade em idosos hospitalizados. Esses resultados podem ser relevantes no manejo e cuidado terapêutico de pacientes hospitalizados.

Abstract Objectives We aimed to evaluate the impact of potentially inappropriate medications prescribed prior to hospitalization (PIM-ph) on the mortality Methods We included 318 patients, aged ≥65 who sought emergency care and were hospitalized for any clinical reasons. Information on patients' clinical and social indicators was obtained via structured interviews conducted 24 to 48 hours after hospitalization. All medications used by older adults prior to hospitalization were recorded, and PIM-ph were identified using the Brazilian PIM Consensus. The study considered the influence of the entire set of PIM-ph and specific PIM-ph used by these patients. The impact of PIM-ph use during hospitalization and after 30 days of this event was statistically determined by multivariable Cox proportional hazard regression analysis, which included sex, age, and other clinical and functional indicators as intervening variables. Results The prevalence of PIM-ph use was 49.7% (n=158). A total of 85 (26.7%) patients died during hospitalization or within 30 days after discharge. Eighteen pharmacological classes of PIM-ph use were identified. The use of total PIM-ph, benzodiazepines (IC: 1.055-3.365, p= 0.032), digoxin(IC: 1.623-7.048, p=0.001), and loop diuretics (IC: 1.000-3.455, p=0.05) increased the relative risk of mortality independent of sex, age, clinical causes of hospitalization, frailty risk, social support, presence of confusion symptoms, polypharmacy, and in-hospital evolution of geriatric complications. Conclusion PIM-ph use, especially benzodiazepines, digoxin, and loop diuretics, could contribute to mortality risk in hospitalized older adults. These results could be relevant in the management and therapeutic care of hospitalized patients.

RESUMO

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

RESUMO

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

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

RESUMO

Background: The use of potentially inappropriate medications (PIM) by the elderly is commonly studied, but studies evaluating the use of PIM by frail elderly covered by prepaid health plans are still lacking. Objective: To identify the prevalence of use and the factors associated with the use of PIM by the elderly patients with high and moderate risk of clinical-functional vulnerability, according to the Beers criteria 2019. Methods: A cross-sectional study was developed with elderly people from a private health plan in Vitória-ES, Brazil. Socioeconomic, demographic and clinical data were collected through a digital platform and a structured questionnaire through an interview, from October 2018 to June 2019. The association between the use of PIM and independent variables was verified by univariate logistic regression with their respective confidence intervals (CI) 95%. The Multiple Model included the variables with P ≤ .20. Results: 332 elderly patients were interviewed (mean age 81.5 years, gender 237 female, 95 male). A 65% prevalence of PIM use was identified. In the multiple logistic regression model, the variables associated with the use of PIM were self-medication (P = .004), high risk of clinical-functional vulnerability (P = .022), use of psychotropic medications (P = .000001), musculoskeletal medications (P = .04) and alimentary tract medications (P = .03). Physical exercises were considered a protection factor (P = .02). Conclusion: The high prevalence of PIM use indicates the need for improvement in elderly private health care, to increase pharmacotherapy safety for this population.

RESUMO

BACKGROUND: Much of the knowledge on the use of potentially inappropriate medications (PIM) in older adults is derived from cross-sectional studies, with little known about the risk factors over time. AIM: Longitudinal analysis was applied to estimate the occurrence and risk factors of PIM use among older adults in a 10-year follow-up. METHOD: Longitudinal study with 418 older adult residents of a capital city of Central-West Brazil. The PIM were classified according to the Beers criteria 2019. The usage rate was calculated at baseline (2008) and at the 10-year follow-up moment (2018). Analysis of predictors (sociodemographic, self-rated health, hospitalization, number of comorbidities, polypharmacy, diabetes, hypertension, hypercholesterolemia and nutritional status) was performed using Generalized Estimating Equation (GEE) models. RESULTS: Mean age at baseline was 70.6 years (SD 7.1) and 76% were women; 221 older adults took part in the follow up. The rate of PIM use was 50.4% at baseline and 57.5% at the 10-year follow-up. Multiple analysis showed that PIM use in the cohort was statistically higher in the older adults with a history of hospitalization (RRadj 1.20; 95% CI 1.01-1.40), with three or more diseases (RRadj 1.41; 95% CI 1.14-1.74), with polypharmacy (RRadj 1.81; 95% CI 1.47-2.24) and with diabetes mellitus (RRadj 1.24; 95% CI 1.05-1.47). CONCLUSION: A high level of potentially inappropriate medication use was observed, reaching 50% of the older adults, with a 7% increase in the prevalence over the 10-year follow-up period. Hospitalization, multimorbidities, polypharmacy and diabetes mellitus were associated with the use of these medications. Interventions for surveillance of the deprescribing process need to be encouraged to avoid potential harm caused by the use of medications.

RESUMO

Resumo Introdução Idosos institucionalizados possuem maiores riscos para a prescrição de cinco ou mais medicamentos, ou polifarmácia, e, por consequência, de eventos adversos, por apresentarem problemas de saúde limitantes, fragilidade e baixa funcionalidade. Esse risco é ainda maior quanto maior o declínio cognitivo. Objetivo Determinar a prevalência de declínio cognitivo (DC) e a relação com o uso de medicamentos em idosos institucionalizados. Método Estudo transversal descritivo realizado por análise de prontuários dos idosos institucionalizados portadores ou não de DC, conforme resultados de testes validados. Foram levantados os medicamentos utilizados e os medicamentos potencialmente inadequados (MPI) por meio dos Critérios de Beers (2015). Resultados Foram avaliados 88 idosos, com idade média de 77,6 (9,2) anos. A prevalência de DC foi de 75%, sendo maior no sexo feminino (82,5%, p = 0,01) e em idosos acima de 80 anos (85%, p = 0,04). Antieméticos e inibidores de bomba de prótons foram significativamente mais utilizados nos idosos com DC. A prevalência de polifarmácia foi de 69,3%, e 71 idosos (80,68%) utilizavam pelo menos um MPI, com maior prevalência do uso de MPI na faixa etária de 60 a 79 anos (p = 0,004). Os idosos que utilizavam pelo menos um MPI também usavam maior número de medicamentos (p = 0,014). Conclusão A presença de DC teve relação com a maior utilização de antieméticos e inibidores de bomba de prótons, mas não com o maior uso de MPI. Além disso, foi observada elevada prevalência de polifarmácia e MPI em prescrições dos idosos institucionalizados.

Abstract Background Institutionalized elderly are at greater risk of prescribing five or more medications and consequently of higher occurence of adverse events, as they have limiting health problems, frailty and low functionality. This risk is even greater if they also have cognitive decline. Objective To determine the prevalence of cognitive disorders (CDs) and its association with the medication used by the institutionalized elderly population of the interior of Minas Gerais, Brazil. Method Descriptive cross-sectional study for analysis of medical records of institutionalized elderly with or without CDs, according to validated tests. The medicine used and the potentially inappropriate medications (PIMs) were determined as per the Beers criteria (2015). Results Eighty eight elderly people, with mean age of 77.6 (9.2) years, were included. CD prevalence was 75% higher in females (82.5%, p = 0.01) and in older age groups, with 80 years and above (85%, p = 0.04). Antiemetics and proton pump inhibitors were significantly more used by the elderly with CDs. The prevalence of polypharmacy was 69.3%, 71 elderlies (80.7%) used at least one PIM, and a higher prevalence of PIM use was observed in elderly people of 60 to 79 years old (p = 0.004). The elderly who used at least one PIM was also observed to use a higher number of medications (p = 0.014). Conclusion CDs was found to be related to the higher use of antiemetics and proton pump inhibitors, but not to the use of PIMs in regards to the institutionalized elderlies. Furthermore, a high prevalence of polypharmacy and PIMs were detected in the prescriptions of the institutionalized elderly subjects.

RESUMO

SUMMARY OBJECTIVE: This study aimed to assess the prevalence of potentially inappropriate medication prescription in hospitalized elderly patients according to the 2019 American Geriatrics Society Beers Criteria. METHODS: This study is a prospective analysis of electronic medical records of elderly patients admitted to the Department of Medicine, Hospital Central da Irmandade da Santa Casa de Misericórdia de São Paulo, between 1 September 2020 and 30 April 2021. RESULTS: A total of 142 patients (85 women and 57 men) with a mean age of 74.5±7.3 years (65-99 years) were assessed. Of these, 108 (76.1%) were elderly (age ≥65 years and <80 years) and 34 (23.9%) long-lived (age ≥80 years). The average length of stay found in the sample was 25.3±28.7 days (between 2 and 235 days), and 102 out of the 140 patients assessed remained in the hospital for up to 29 days. Sixteen drugs considered potentially inappropriate medication were found in the patients' prescriptions, with at least one potentially inappropriate medication having been prescribed to 141 (99.3%) patients. Elderly patients had a mean of 2.57±0.94 potentially inappropriate medication prescribed versus 2.56±0.89 among long-lived patients. The most prescribed potentially inappropriate medication were as follows: regular human insulin as required (85.2%), and omeprazole (73.9%) and metoclopramide as required (61.3%). CONCLUSION: The study sample showed significant percentages of potentially inappropriate medication prescriptions for the elderly admitted to the hospital.

RESUMO

The high prevalence of PIMs in elderly is a major healthcare concern and indicates the need for medication monitoring systems. Most PIM CDSS have shown positive effects respecting PIM prescription but these results were more consistently in hospital settings compared with ambulatory care. We describe the post-implementation evaluation of a PIM CDSS for general practitioners (GP) in the ambulatory setting and explore GP interactions with the PIM alerts. The CDSS generated 3218 unique alerts and involved 2863 elderly patients. Benzodiazepines was the drug with the most alerts triggered. Only 129 (4 %) were opened by GP during patient appointments. We need to develop an understanding of how alerts should be designed and display information to support the workflow of general practitioners. Pos-implementation evaluations are the key of CDSS improvements.

RESUMO

OBJECTIVE: To map explicit screening tools to identify potentially inappropriate medication (PIMs), and the characteristics and limitations of these tools. Including PIMs-interactions, therapeutic alternatives and the clinical management of PIMs. METHODS: A systematic scoping review was conducted in PubMed and Scopus (until May 2021). The number of PIMs listed as essential drugs was identified in Model List of Essential Medicines by the World Health Organization (WHO) and National List of Essential Medicines (Brazil). In addition to reporting the therapeutic alternatives and clinical management proposed by explicit screening tools to identify PIMs, we suggested our own alternatives for the PIMs most frequently reported. RESULTS: Fifty-eight tools reported 614 PIMs and 747 PIMs-interactions. Limited overlap between the tools was observed: 123 (69.1%) of 178 therapeutic alternatives proposed by the tools were considered inappropriate by other tools, and 222 (36.1%) of the 614 PIMs identified were named as being inappropriate only once. Only 21 tools were developed by a Delphi panel technique associated with systematic review. The PIMs listed as essential medication in Brazil and by the WHO were 30.6% and 23.3% of the total reported, respectively. For the most-cited PIMs, such as non-steroidal anti-inflammatory drugs, tricyclic antidepressants and benzodiazepines, we suggested the use of non-opioid and opioid analgesics; agomelatine, bupropion or moclobemide; and melatonin, respectively. CONCLUSIONS: The next stages in the development of explicit screening tools to identify PIMs include achieving more consensus between them and improving their applicability across countries. Further, it is recommended that tools include PIMs risks and advice on therapeutic alternatives.

RESUMO

ABSTRACT Objective To examine associations between potentially inappropriate medication, use and the risk of falls, unplanned hospitalization and death in older patients receiving initial care in a geriatric day hospital due to acute conditions. Methods Cohort study with older adults referred to a geriatric day hospital from 2014 to 2017 due to acute conditions. Patients were submitted to comprehensive geriatric assessment. Use of medications was analyzed according to Beers Criteria 2019. Outcome assessment was based on monthly follow-up telephone calls made over the course of one year. Results In this sample, 40.6% of patients had been prescribed at least one potentially inappropriate medication, particularly proton pump inhibitors (66.5%). Over the course of follow-up, 44.7% of patients receiving potentially inappropriate medications sustained at least one fall (p=0.0043) and 70% visited the emergency department (p=0.0452). These outcomes were more common among patients using two or more of drugs. Use of potentially inappropriate medication was associated with a 64% increase in the odds of unplanned hospitalization and a two-fold increase in risk of death. Conclusion Associations between potentially inappropriate medication use and unfavorable outcomes such as falls and unplanned hospitalizations within one year of admission to a geriatric day hospital support the application of Beers Criteria and emphasize the importance of periodic prescription review, deprescription and rational use of these drugs whenever possible.

RESUMO

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.

RESUMO

SUMMARY OBJECTIVE: This study aimed to evaluate the relationship between hospital admission potentially inappropriate medications use (PIM) and in-hospital mortality of COVID-19, considering other possible factors related to mortality. METHODS: The Turkish inappropriate medication use in the elderly (TIME) criteria were used to define PIM. The primary outcome of this study was in-hospital mortality. RESULTS: We included 201 older adults (mean age 73.1±9.4, 48.9% females). The in-hospital mortality rate and prevalence of PIM were 18.9% (n=38) and 96% (n=193), respectively. The most common PIM according to TIME to START was insufficient vitamin D and/or calcium intake per day. Proton-pump inhibitor use for multiple drug indications was the most prevalent PIM based on TIME to STOP findings. Mortality was related to PIM in univariate analysis (p=0.005) but not in multivariate analysis (p=0.599). Older age (hazards ratio (HR): 1.08; 95% confidence interval (CI): 1.02-1.13; p=0.005) and higher Nutritional Risk Screening 2002 (NRS-2002) scores were correlated with in-hospital mortality (HR: 1.29; 95%CI 1.00-1.65; p=0.042). CONCLUSION: Mortality was not associated with PIM. Older age and malnutrition were related to in-hospital mortality in COVID-19.
