Anti-dementia drugs: what is the evidence in advanced stages?

Dementia is a major public health concern due to its increasing prevalence, substantial caregiver burden, and high financial costs. Currently, the anti-dementia drugs aim only at a symptomatic effect. The subject of prescribing these drugs in advanced stages is a matter of considerable debate, with different countries making distinct recommendations. In this review article, we analyzed the evidence regarding cognitive and functional outcomes, adverse events, health-related costs, and caregiver burden in patients with advanced Alzheimer disease (AD) and mixed dementia. We included 35 studies. Most studies are heterogeneous, focus exclusively on AD, and show small benefits in terms of cognitive and functional scales. The overall evidence seems to suggest a benefit in introducing or maintaining anti-dementia drugs in patients with advanced dementia, but clinical meaningfulness is difficult to ascertain. The issue of costs and caregiver burden is significantly underexplored in this field but also seems to favor treatment continuation, despite a reduced overall effect. The decision of introducing or withdrawing anti-dementia drugs in advanced stages of dementia should be individualized. Future studies with homogeneous designs and outcomes are warranted.

Drug prescription appropriateness in hospitalized older patients: 15-year results and lessons from a countrywide register.

The global increase of aging with the related increase of multiple noncommunicable diseases is inevitably accompanied by the associated issue of multimorbidity and polypharmacy. The latter is not without peculiar consequences on health, because it has been shown to be associated with drug-related adverse events, mainly due to poor prescription appropriateness and drug-drug interactions. To contribute to tackle this gigantic problem, a registry of drug dispensation in hospitalized older patient has been initiated in Italy in 2008. Through the last 15 years, data on nearly 11,000 older people have been accrued during their hospital stay in internal medicine and geriatric wards. This review article summarizes the main findings obtained, and how these data contribute to tackle the issue of appropriateness of drug prescription and the need of deprescribing in hospitalized older people affected by the most common noncommunicable diseases.

Deprescribing: An umbrella review.

This umbrella review examined systematic reviews of deprescribing studies by characteristics of intervention, population, medicine, and setting. Clinical and humanistic outcomes, barriers and facilitators, and tools for deprescribing are presented. The Medline database was used. The search was limited to systematic reviews and meta-analyses published in English up to April 2022. Reviews reporting deprescribing were included, while those where depre-scribing was not planned and supervised by a healthcare professional were excluded. A total of 94 systematic reviews (23 meta--analyses) were included. Most explored clinical or humanistic outcomes (70/94, 74 %); less explored attitudes, facilitators, or barriers to deprescribing (17/94, 18 %); few focused on tools (8/94, 8.5 %). Reviews assessing clinical or humanistic outcomes were divided into two groups: reviews with deprescribing intervention trials (39/70, 56 %; 16 reviewing specific deprescribing interventions and 23 broad medication optimisation interventions), and reviews with medication cessation trials (31/70, 44 %). Deprescribing was feasible and resulted in a reduction of inappropriate medications in reviews with deprescribing intervention trials. Complex broad medication optimisation interventions were shown to reduce hospitalisation, falls, and mortality rates. In reviews of medication cessation trials, a higher frequency of adverse drug withdrawal events underscores the importance of prioritizing patient safety and exercising caution when stopping medicines, particularly in patients with clear and appropriate indications.

Prescriber Acceptability of a Direct-to-Patient Intervention for Benzodiazepine Receptor Agonist Deprescribing and Behavioural Management of Insomnia in Older Adults.

Behavioural treatments are recommended first-line for insomnia, but long-term benzodiazepine receptor agonist (BZRA) use remains common and engaging patients in a deprescribing consultation is challenging. Few deprescribing interventions directly target patients. Prescribers' support of patient-targeted interventions may facilitate their uptake. Recently assessed in the Your Answers When Needing Sleep in New Brunswick (YAWNS NB) study, Sleepwell (mysleepwell.ca) was developed as a direct-to-patient behaviour change intervention promoting BZRA deprescribing and non-pharmacological insomnia management. BZRA prescribers of YAWNS NB participants were invited to complete an online survey assessing the acceptability of Sleepwell as a direct-to-patient intervention. The survey was developed using the seven construct components of the theoretical framework of acceptability (TFA) framework. Respondents (40/250, 17.2%) indicated high acceptability, with positive responses per TFA construct averaging 32.3/40 (80.7%). Perceived as an ethical, credible, and useful tool, Sleepwell also promoted prescriber-patient BZRA deprescribing engagements (11/19, 58%). Prescribers were accepting of Sleepwell and supported its application as a direct-to-patient intervention.

Impact of Glucagon-Like Peptide 1 Agonist Deprescription in Type 2 Diabetes in a Real-World Setting: A Propensity Score Matched Cohort Study.

INTRODUCTION: Glucagon-like peptide 1 receptor agonists (GLP-1) elicit substantial reductions in glycemia and body weight in people with type 2 diabetes (T2D) and obesity, but existing data suggest the therapy must be continued indefinitely to maintain clinical improvements. Given the high cost and poor real-world persistence of GLP-1, an effective therapy that enables deprescription with sustained clinical improvements would be beneficial. Thus, the purpose of this real-world study was to assess the effect of GLP-1 deprescription on glycemia and body weight following co-therapy with carbohydrate restricted nutrition therapy (CRNT) supported via telemedicine in a continuous remote care model. METHODS: A retrospective, propensity score matched cohort study among patients with T2D at a telemedicine clinic was conducted. Patients in whom GLP-1 were deprescribed (DeRx; n = 154) were matched 1:1 with patients in whom GLP-1 were continued (Rx). HbA1c and body weight at enrollment in clinic (pre-CRNT), at date of deprescription or index date (derx/ID), and at 6 and 12 months (m) post-derx/ID were utilized in this study. RESULTS: No regression in weight was observed following deprescription with > 70% maintaining ≥ 5% weight loss 12 m post-derx/ID. HbA1c rose 6 m and 12 m post-derx/ID in both DeRx and Rx cohorts, but most patients maintained HbA1c < 6.5%. HbA1c and body weight measured 6 m and 12 m following derx/ID did not significantly differ between cohorts and were improved at derx/ID and at follow-up intervals compared to pre-CRNT. CONCLUSION: These results demonstrate the potential for an alternate therapy, such as CRNT supported via telemedicine, to enable maintenance of weight loss and glycemia below therapeutic targets following discontinuation of GLP-1 therapy.

Reducing the drug burden of sedative and anticholinergic medications in older adults: a scoping review of explicit decision criteria.

OBJECTIVES: To describe the extent, characteristics, and knowledge gaps regarding explicit decision criteria for deprescribing drugs with anticholinergic or sedative properties (Ach/Sed) in older adults. DESIGN: Scoping review. SETTING AND PARTICIPANTS: Original studies, clinical trial protocols, grey literature, and Summaries of Product Characteristics. METHODS: Searches targeting explicit decision criteria for deprescribing Ach/Sed were performed across MEDLINE, EMBASE, CINAHL, and Web of Science, including trial registries (clinicaltrials.gov, ICTRP, EU-CTR, ANZCTR) for pertinent articles, study protocols. Additionally, to encompass non-traditional or 'grey literature' sources, Google searches and relevant agency websites were explored, alongside the summary of product characteristics for Ach/Sed. RESULTS: The initial literature search identified 8,192 unique data sources. After review, 188 original articles or books, 79 internet sources, and 127 SmPCs were included. Examining these sources for explicit criteria for 154 Ach/Sed, overall, 1,271 explicit criteria guidance for identifying clinical scenarios warranting deprescription of Ach/Sed across 145/154 Ach/Sed were identified. These criteria were identified mainly from qualitative research and Summaries of Product Characteristics. Additionally, 455 criteria-based recommendations suggesting approaches for tapering implementation across 76/154 Ach/Sed were identified, mostly from sources classified as expert opinions. Significant heterogeneity was found across the approaches for tapering Ach/Sed. CONCLUSIONS: This scoping review provides a comprehensive overview of the literature providing guidance for clinical scenarios where Ach/Sed should be deprescribed and highlights the existing knowledge gaps regarding comprehensive guidance on tapering these drugs which warranties future research and development.

Impact of palliative care at end-of-life Covid-19 patients - a small-scale pioneering experience.

BACKGROUND: In March 2020, the outbreak caused by the SARS-CoV-2 virus was declared a pandemic, resulting in numerous fatalities worldwide. To effectively combat the virus, it would be beneficial to involve professionals who specialize in symptom control for advanced illnesses, working closely with other specialties throughout the illness process. This approach can help manage a range of symptoms, from mild to severe and potentially life-threatening. No studies have been conducted in Portugal to analyse the intervention of Palliative Medicine at the end of life of Covid-19 patients and how it differs from other specialties. This knowledge could help determine the importance of including it in the care of people with advanced Covid-19. OBJECTIVES: The objective of this study is to examine potential differences in the care provided to patients with Covid-19 during their Last Hours and Days of Life (LHDOL) between those who received care from Palliative Medicine doctors and those who did not. METHODS: This is a retrospective cohort study spanning three months (Dec 2020 to Feb 2021), the duration of the Support Unit especially created to deal with Covid-19 patients. The database included clinical files from 181 patients admitted to the Support Unit, 27 of which died from Covid-19. RESULTS: Statistically significant differences were identified in the care provided. Specifically, fewer drugs were administered at the time of death, including drugs for dyspnoea, pain and agitation, suspension of futile devices and use of palliative sedation to control refractory symptoms. CONCLUSIONS: End-of-life care and symptomatic control differ when there's regular follow-up by Palliative Medicine, which may translate less symptomatic suffering and promote a dignified and humane end of life.

Chronic benzodiazepine usage among older people: prevalence, indications, and treatment modifications in patients admitted to an acute geriatric unit.

AIM: To investigate the prevalence and indications of benzodiazepines (BZD) usage among patients admitted to an acute geriatric unit and assess changes in prescriptions. METHODS: BZD indications were documented reviewing clinical records, with appropriateness assessed based on the STOPP-START criteria. Changes in BZD prescriptions were recorded at discharge and 3 months later. RESULTS: Among the 366 patients included (mean age: 92.8 years, 68% females), 91 (24.9%) were on BZD upon admission, being inappropriate in 93.4%. At discharge, BZD discontinuation was observed in 40.7% and dose reduction initiated in 57.4%. Among patients discharged without prescriptions, 10.8% resumed their use at 3 months. Of those discharged with BZD tapering, 74.1% were still on them 3 months later. CONCLUSIONS: The majority of patients employing BZD lacked a medical indication. Admission to a geriatric ward resulted in successful discontinuation or dose reduction for most patients but was not maintained in the outpatient setting.

Barriers and Enablers for Deprescribing Glucose-Lowering Treatment in Older Adults: A Systematic Review.

OBJECTIVES: Overtreatment with glucose-lowering treatment (GLT) is frequent and a source of high morbidity and mortality in older adults with type 2 diabetes mellitus (T2DM). This study aimed to identify and synthesize barriers and enablers for deprescribing GLT in older adults (≥65 years) with T2DM. DESIGN: Systematic review of qualitative and mixed-methods studies. SETTING AND PARTICIPANTS: Older adults with T2DM, any participants [patients, health care providers (HCPs), caregivers], any settings. METHODS: Two researchers (and a referred third researcher at all stages) independently screened original articles reporting qualitative and mixed-methods studies exploring barriers and enablers for deprescribing GLT in older adults published during 2010-2023, identified from MEDLINE, Embase, CINAHL, and gray literature. Quality of the included studies was assessed with the Mixed-Methods Appraisal Tool. Verbatim statements on barriers and enablers were extracted, and determinants of behaviors were identified with the Theoretical Domains Framework (TDF) version 2, and related intervention functions (targets for future interventions) were proposed according to the Behavior Change Wheel (BCW). RESULTS: We identified only 4 studies from 2 countries (United States and the Netherlands), all recently published (2019-2023), that primarily reported barriers to GLT deprescribing from interviews or focus groups of patients or HCPs practicing outpatient medicine. Knowledge, fear, poor communication, inertia, and trust with HCPs were the main determinants of behaviors that influenced deprescribing, and education, training, persuasion and environmental restructuring were the main intervention functions for proposing future interventions. Studies did not cover financial aspects, physician characteristics, or caregiver and family viewpoints. CONCLUSIONS AND IMPLICATIONS: The use of a behavioral theory and a validated implementation framework provided a comprehensive approach to identifying barriers and enablers for deprescribing GLT in older adults (≥65 years) with T2DM. The behavioral determinants identified may be useful in tailoring interventions to improve the implementation of GLT deprescribing in older adults in ambulatory settings.

Bastidores da prescrição de inibidores de bomba de prótons: uma pesquisa internacional sobre práticas e conhecimentos médicos / Behind the proton pump inhibitor prescription: an international survey on physician practices and knowledge

ABSTRACT Background: Proton pump inhibitors (PPIs) are widely prescribed worldwide, often resulting in their overuse. Consequently, it is essential to identify the likely causes of this overuse to facilitate their appropriate prescription. Objective: This study aims to assess physician prescribing patterns, their knowledge of PPIs, and factors affecting their knowledge. Methods: An online survey was conducted among Latin American and Spanish physicians, collecting the following data: professional information, patterns of PPI usage, familiarity with published evidence, and the management approach in three hypothetical case-scenarios. Participant knowledge was categorized as sufficient or insufficient based on the results of the case scenarios. Subsequently, subgroup analysis was performed based on physician training level, years in practice, specialty, and time since the last PPI literature review. Results: A total of 371 physicians participated in the survey. Thirty-eight percent frequently prescribe PPIs, primarily for prophylactic purposes (57.9%). Eighty percent were unfamiliar with PPI deprescribing strategies, and 54.4% rarely reviewed the ongoing indication of patients taking a PPI. Sixty-four percent demonstrated sufficient knowledge in the case-scenarios. A significant association was observed between specialty type (medical vs surgical: 69.4% vs 46.8%, P<0.001), the timing of the PPI indication literature review (<5 years vs >5 years: 71.4% vs 58.7%, P=0.010), and sufficient knowledge. Conclusion: While most participants prescribed PPIs regularly and for prophylaxis purposes, the majority were unfamiliar with deprescribing strategies and rarely reviewed ongoing indications. Sufficient knowledge is correlated with recent literature reviews and medical specialty affiliation.

RESUMO Contexto: Os inibidores da bomba de prótons (IBPs) são amplamente prescritos em todo o mundo, muitas vezes resultando em seu uso excessivo. Consequentemente, é essencial identificar as prováveis causas desse uso excessivo para facilitar sua prescrição adequada. Objetivo: Este estudo tem como objetivo avaliar o padrão de prescrição dos médicos, seu conhecimento sobre IBPs e fatores que afetam seu conhecimento. Métodos: Uma pesquisa on-line foi conduzida entre médicos latino-americanos e espanhóis, coletando os seguintes dados: informações profissionais, padrões de uso de IBP, familiaridade com evidências publicadas e abordagem de manejo em três casos-cenários hipotéticos. O conhecimento dos participantes foi categorizado em suficiente ou insuficiente com base nos resultados dos cenários de caso. Posteriormente, a análise de subgrupos foi realizada com base no nível de formação do médico, anos de prática, especialidade e tempo desde a última revisão da literatura dos IBPs. Resultados: Um total de 371 médicos participaram da pesquisa. Trinta e oito por cento prescrevem frequentemente IBP, principalmente para fins profiláticos (57,9%). Oitenta por cento não estavam familiarizados com as estratégias de prescrição de IBP, e 54,4% raramente revisaram a indicação contínua de pacientes em uso de IBP. Sessenta e quatro por cento demonstraram conhecimento suficiente nos cenários-caso. Observou-se associação significativa entre o tipo de especialidade (médica vs cirúrgica: 69,4% vs 46,8%, P<0,001), o momento da revisão da literatura de indicação do IBP (<5 anos vs >5 anos: 71,4% vs 58,7%, P=0,010) e conhecimento suficiente. Conclusão: Embora a maioria dos participantes prescrevesse IBPs regularmente e para fins de profilaxia, no entanto, não estava familiarizada com estratégias de prescrição e raramente revisava as indicações em andamento. O conhecimento suficiente está correlacionado com revisões recentes da literatura e afiliação à especialidade médica.

The Risk of Drug Interactions in Older Primary Care Patients after Hospital Discharge: The Role of Drug Reconciliation.

INTRODUCTION: Drug-drug interactions (DDIs) represent an important clinical problem, particularly in older patients, due to polytherapy, comorbidity, and physiological changes in pharmacodynamic and pharmacokinetic pathways. In this study, we investigated the association between drugs prescribed after discharge from the hospital or clinic and the risk of DDIs with drugs used daily by each patient. METHODS: We performed an observational, retrospective, multicenter study on the medical records of outpatients referred to general practitioners. DDIs were measured using the drug interaction probability scale. Potential drug interactions were evaluated by clinical pharmacologists (physicians) and neurologists. Collected data were analyzed using the Statistical Package for the Social Sciences. RESULTS: During the study, we evaluated 1772 medical records. We recorded the development of DDIs in 10.3% of patients; 11.6% of these patients required hospitalization. Logistic regression showed an association among DDIs, sex, and the number of drugs used (p = 0.023). CONCLUSIONS: This observational real-life study shows that the risk of DDIs is common in older patients. Physicians must pay more attention after hospital discharge, evaluating the treatment to reduce the risk of DDIs.

Deprescripción en personas mayores: es el momento de pasar a la acción / Deprescription in old people: It's time to take action

El uso de fármacos conlleva innegables beneficios en las personas mayores, pero no está exento de efectos indeseables. La deprescripción es el proceso de revisión sistemática de la medicación con el objetivo de lograr la mejor relación riesgo-beneficio en base a la mejor evidencia disponible. Este proceso es especialmente importante en mayores polimedicados, sobretratados, frágiles, con enfermedades terminales y en el final de la vida.La deprescripción debe hacerse de forma escalonada, estableciendo un seguimiento estrecho por si aparecen problemas tras la retirada. En la toma de decisiones es muy importante contar con la opinión del paciente y de los cuidadores, valorando los objetivos del tratamiento según la situación clínica, funcional y social del enfermo.Existen múltiples herramientas para facilitar a los clínicos la tarea de seleccionar qué fármacos deprescribir (criterios Beers, STOPP-START…). Los grupos farmacológicos más susceptibles de intervención son: antihipertensivos, antidiabéticos, estatinas, benzodiacepinas, antidepresivos, anticolinérgicos, anticolinesterásicos y neurolépticos.(AU)

The use of drugs has undeniable benefits to the elderly, but it is not exempt from undesirable effects. Deprescription is the process of systematic medication review with the target of achieving the best risk-benefit ratio based on the best available evidence. This process is especially important for polymedicated elderly patients as well as those overtreated, frail, terminally ill and at the end of life.The deprescription must be done in stages, establishing a close follow-up in case problems appear after withdrawal. In the decision-making process, it is very important to consider the patient and caregivers opinion, assessing the objectives of the treatment according to the clinical, functional and social situation of the patient.There are multiple tools to make it easier for clinicians to select which drugs to deprescribe (Beers criteria, STOPP-START…). The most susceptible to intervention pharmacological groups are: antihypertensives, antidiabetics, statins, benzodiazepines, antidepressants, anticholinergics, anticholinesterase agents, and neuroleptics.(AU)

Polifarmacia en paciente VIH mayor de 50 años / Polypharmacy in HIV patient older than 50 years

Introducción: Los pacientes con virus de la inmunodeficiencia humana (VIH) han aumentado su esperanza de vida, convirtiéndose así el VIH en una enfermedad crónica gracias al tratamiento antirretroviral (TAR), que aunque no sea capaz de erradicar el virus, mantiene la carga viral suprimida e incrementa el número de linfocitos-CD4. Consecuentemente, ha aumentado el número de comorbilidades en esta población, y con ello su polifarmacia.Objetivo: Analizar la medicación TAR y no-TAR de pacientes VIH ≥50 años, determinando el grado de polifarmacia y las interacciones potenciales relevantes.Material y métodos: Estudio retrospectivo, observacional, unicéntrico, analítico, transversal. Se incluyeron los pacientes VIH ≥50 años que acudieron al Servicio de Farmacia para recogida de medicación: 7-enero al 3-febrero, 2019. Se recogieron las variables: edad, sexo, estratificación según la Estrategia de Atención Farmacéutica al Paciente Crónico de Jimena®, TAR y medicación no-TAR.Resultados: Se incluyeron un total de 114 pacientes ≥50 años, el 96,97% tenía medicación concomitante, destacando fármacos para el sistema cardiovascular y para el sistema nervioso central (SNC). Se identificaron 99 interacciones potenciales significativas TAR/no-TAR en 66 pacientes, ocurriendo principalmente con los fármacos para el SNC. Los TAR principalmente implicados fueron los inhibidores de la transcriptasa inversa no análogos de nucleósidos, inhibidores de la proteasa potenciados e inhibidores de la integrasa potenciados (INI/p).Conclusiones: El médico prescriptor del TAR debe tener en cuenta la polifarmacia de estos pacientes, intentar desprescribir medicación innecesaria en la medida de lo posible y buscar alternativas con menor repercusión, como puede ser el uso de INI en el contexto del TAR. (AU)

Background: Human immunodeficiency virus (HIV) in patients have increased their life expectancy, making HIV a chronic illness, thanks to the antiretroviral treatment (ART), which, despite the fact it is not able to eradicate the HIV, it keeps the viral load supressed and increases the number of CD4 lymphocytes. Consequently, the number of comorbidities in this population has increased so, its polypharmacy as well.Objective: To analyze the ART and non-ART medication of HIV patients ≥50 years old, determining the degree of polypharmacy and relevant interactions.Material and methods: Observational retrospective study, mono-site, analytical and transversal. HIV patients ≥50 years old who went to the Pharmacy Service for collecting medication from January 7th untill February 3rd, 2019. The following variables were selected: age, sex, stratification according to the Strategy of Pharmaceutical Care to the Patient Chronic of Jimena®, ART and non-ART medication.Results: A total of 114 patients ≥50 years old were included, 96.97% had concomitant medication, highlighting drugs for the cardiovascular system and for the central nervous system. 99 significant interactions ART/non-ART were identified in 66 patients, occurring mainly with drugs for the central nervous system. The ARTs mainly involved were the non-nucleoside reverse transcriptase inhibitors, boosted protease inhibitors and boosted integrase inhibitors (INI).Conclusions: Prescribe physicians of ARTs must take into account to the polypharmacy of the patients, try to deprescribe unnecessary medication as much as possible and find alternatives with less repercussion, such as the use of Inhibitors of the Integrase, in the context of ART.

Protocolo del estudioEstrategia de deprescripción deestatinas y ezetimiba en prevenciónprimaria en mayores de 75 años: análisis de los resultados en salud / Study protocol: A strategy for deprescribing statins and ezetimibe in primary prevention of cardiovascular disease in patients older than 75 years: health outcomes analysis

FUNDAMENTOS: l balance beneficio-riesgo de estatinas y ezetimiba como prevención primaria de la enfermedad cardiovascular (ECV) resulta controvertido en pacientes de edad avanzada, debido a las dudas sobre su efectividad y las certezas sobre efectos adversos. El objetivo de este estudio fue analizar los resultados en salud de una estrategia de deprescripción de estatinas y ezetimiba en prevención primaria de ECV en pacientes mayores de 75 años. MÉTODOS: Se realizó un estudio ambispectivo de cohortes para evaluar los resultados en salud obtenidos tras la implementación de una estrategia poblacional de deprescripción de estatinas y ezetimiba en pacientes con edad igual o mayor a 75 años que tomaban estos fármacos como prevención primaria de ECV. Para evitar posibles sesgos debidos a la asignación no aleatoria de los pacientes a los distintos grupos, se calculará un índice de propensión para cada paciente utilizando una regresión logística, en la que la variable de resultado será la deprescripción o no de estatinas o ezetimiba. Se analizará el tiempo hasta el ingreso hospitalario o la muerte por cualquier causa y otras variables relacionadas con resultados en salud. Se compararán los grupos con y sin deprescripción de estatina o ezetimiba mediante un análisis de supervivencia utilizando un modelo de riesgos proporcionales de Cox para estimar el hazard ratio. CONCLUSIONES: Se espera obtener información sobre los resultados en salud de la estrategia de deprescripción de estatinas y ezetimiba en prevención primaria en mayores de 75 años que informarán sobre la conveniencia de continuarla.(AU)

BACKGROUND: The benefit-risk balance of statins and ezetimibe as primary prevention of cardiovascular disease is controversial in elderly patients due to the doubts about their effectiveness and certainty about adverse effects. The aim of this paper was to analyze health outcomes of a statin and ezetimibe deprescription strategy in patients aged 75 or older treated with these drugs for primary prevention of cardiovascular disease. METHODS: An observational ambispective cohort study was made to evaluate health outcomes after the implementation of a strategy for deprescribing statins and ezetimibe in patients aged 75 or older who take these drugs for primary prevention of cardiovascular disease. To avoid the risk of bias due to non-random assignment of patients to different groups, a propensity score will be calculated for each patient using logistic regression. The outcome of interest will be the deprescription or not of statins or ezetimibe. Time to hospital admission or death from any cause and other variables related to health outcomes will be analysed. Groups with and without statin or ezetimibe deprescription will be compared by survival analysis using Cox regression to estimate the hazard ratio. CONCLUSIONS: It is expected to obtain health outcomes of the strategy of deprescribing statins and ezetimibe in primary prevention in patients aged 75 or older. They will provide information on the advisability of continuing the strategy.(AU)

Deprescripción de medicamentos en pacientes adultos mayores: una revisión de la literatura / Deprescribing medications for elderly patients: a narrative review

Dado el envejecimiento poblacional que vive Chile, se hace cada vez más importante evaluar la seguridad y uso de medicamentos en adultos mayores. Una de las estrategias propuestas a nivel internacional es la deprescripción, que consiste en la disminución o eliminación de fármacos utilizados como tratamiento habitual. Para ello se diseñó esta revisión narrativa que pretendeofrecer un análisis de la literatura de la deprescripción de medicamentos en adultos mayores, con el fin de promover su práctica. Se realizó una búsqueda de artículos publicados entre los años 2003 al 2021, en bases de datos como Science Direct, MEDLINE, TripdataBase y Web of Science, seleccionando aquellos con mayor nivel de evidencia. Según la revisión la deprescripción, en general, se define como un proceso de retirada de la medicación inapropiada, bajo la supervisión de un profesional; siendo su principal causa la presencia de polifarmacia, y la prescripción de medicamentos potencialmente inapropiados. Los principales fármacos deprescritos con éxito (sin necesidad de ser reincorporados) corresponden a benzodiazepinas, antipsicóticos atípicos, corticoides, antidepresivos tricíclicos, estatinas e inhibidores de la bomba de protones. En conclusión: la deprescripción es un proceso poco estudiado, especialmente a nivel local; sin embargo, existe suficiente evidencia que avala la disminución los problemas de salud, en especial los referidos a la seguridad de la farmacoterapia en los adultos mayores.

It is becoming increasingly important to evaluate the safety and use of medications in older people in Chile, given the ageing of its population. Deprescription, which is defined as the reduction or elimination of drugs used by a given patient, is one of the strategies, proposed at the international level, to improve the safety of the pharmacotherapy. For this reason, this narrative review was designed, which aims to offer an analysis of the literature on medication deprescription in older adults, to promote its practice. For this, a search of articles published between 2003 and 2021 was performed in databases such as Science Direct, MEDLINE, TripdataBase, and Web of Science. The articles with the highest level of evidence were selected. It was found that deprescription, in general, is defined as a process of withdrawal of inappropriate drugs under the supervision of a healthcare professional; its leading cause is the presence of polypharmacy and the prescription of potentially problematic medications. The main medicines successfully deprescribed (without reincorporation) were benzodiazepines, atypical antipsychotics, corticosteroids, tricyclic antidepressants, statins, and proton pump inhibitors. In conclusion: deprescription is a poorly studied process, especially at the local level; however, there is sufficient evidence to support the reduction in health problems, especially those related to the safety of pharmacotherapy in the elderly.

Uso práctico de inhibidores de bomba de protones / Practical use of proton pump inhibitors / Uso prático de inibidores da bomba de prótons

Los inhibidores de la bomba de protones (IBP) se encuentran entre los medicamentos más utilizados en el mundo por su bajo costo, extensa prescripción y efectividad. Sin embargo, su uso a largo plazo no es inocuo y aún hay vacíos en el conocimiento del empleo adecuado de estos medicamentos. Por lo tanto, en esta revisión se expone, además de sus propiedades generales, sus verdaderas indicaciones, el uso recomendado a largo plazo y las estrategias para lograr la deprescripción, con el fin de evitar el uso indiscriminado.

Proton pump inhibitors (PPIs) are among the most widely used drugs in the world, due to their low cost, extensive prescription and effectiveness. However, its long-term use is not safe and there are still certain gaps in the knowledge of the proper use of these drugs. Therefore, this review aims to expose their general properties as well as their true indications, the appropriate long-term use and strategies to achieve adequate deprescription of these drugs, seeking to avoid indiscriminate use.

Os inibidores da bomba de prótons (IBP) se encontram entre os medicamentos mais utilizados no mundo pelo seu baixo custo, extensa prescrição e efetividade. Embora, seu uso a longo prazo não é inócuo e ainda há vazios no conhecimento do uso adequado destes medicamentos. Por tanto, nesta revisão se expõe, além das suas propriedades gerais, suas verdadeiras indicações, o uso recomendado ao longo prazo e as estratégias para conseguir a deprescrição, com o fim de evitar o uso indiscriminado.

¿Conlleva la desprescripción de condroprotectores en pacientes con artrosis un incremento del consumo de analgésicos? Estudio observacional retrospectivo / Does the deprescription of chondroprotectors in patients with osteoarthritis lead to an increase in the consumption of analgesics? Observational retrospective study

Objetivo: El objetivo del estudio es evaluar si la desprescripción de medicamentos considerados de bajo valor intrínseco como los condroprotectores o SYSADOA, conlleva un empeoramiento sintomáti-co de la artrosis, incrementándose el consumo de analgésicos.Material y métodos: Siguiendo la práctica clínica habitual se retiró el tratamiento con SYSADOA a pa-cientes de un Centro de Atención Primaria (pobla-ción asignada: 34.382 habitantes, 17% mayores de 65 años) en base a la evidencia científica publicada y a la recomendación de la administración sanitaria de reducir los tratamientos con medicamentos de bajo valor intrínseco. Mediante un estudio obser-vacional post-intervención se analizaron diferen-cias de consumo de analgésicos y AINEs entre un periodo anterior a la retirada y el mismo periodo post-retirada.Resultados: Se analizaron 354 pacientes (68,4% mujeres, media de edad 66,2 años). No se encon-traron diferencias estadísticamente significativas en el consumo de analgesia total en el periodo de 6 meses post-retirada (media de 3,97 envases) com-parado con el periodo de 6 meses previo (media de 4,04 envases). Al estratificar por código ATC, edad y género, únicamente se encontraron diferencias en el consumo de otros analgésicos y antipiréticos teniendo en cuenta el sexo.Conclusión: Se concluye que, considerar con el paciente la desprescripción de SYSADOA a criterio del médico, es seguro y no conlleva un aumento del consumo de analgésicos (otros analgésicos y anti-piréticos, AINE, opioides menores, opioides mayo-res) sugiriendo que no implica un empeoramiento de la enfermedad artrósica. La desprescripción de SYSADOA, además, puede contribuir a reducir la po-limedicación sin alterar la situación clínica y evitar posibles riesgos de efectos adversos o interaccio-nes potenciales (AU)

Objective: The objective of this study is to assess if the deprescription of medications that are consid-ered low intrinsic value medications such as the chondroprotectors or SYSADOA entails a symptom-atic worsening of the arthrosis and consequently an increase of the consumption of analgesics.Material and Methods: Following the usual clinical practise, the SYSADOA treatment was withdrawn to the patients from a Primary Health Care Centre (assigned population: 34,382 inhabitants, 17% up to 65 years old) according to the published scientific proof and the recommendation of the health ad-ministration consisting of reducing the treatments with low intrinsic value medications. Differences in consumption of analgesics and AINEs between a previous period before the withdrawn and the same period post-withdrawn were studied through an observational post-intervention study.Results: 354 patients were analysed (68,4% wom-en, average age 66,2 years). There were not found significant differences from a statistical point of view in the total consumption of analgesia in the 6 months period post-withdrawn (average of 3,97 packagings) compared to the previous period of 6 months (average of 4,04 packagings). When stratifying by ATC code, age and gender, there were only found differences in the consumption of other analgesics and antipyretics taking into account the sex.Conclusion: It is concluded that considering togeth-er with the patient the deprescription of SYSADOA according to doctor’s criteria is safe and does not involve an increase of analgesics consumption (other analgesics, antipyretics, AINEs, major and minor opiods) suggesting that it does not suppose a worsening of the arthrosis disease. Besides, the deprescription of SYSADOA may contribute to re-duce polymedication without disrupting the clinical situation and avoid possible risks of adverse effects or potential interactions
