Sedative use and incidence of falls and hip fractures among older adults in an outpatient geriatric clinic / Perfil de uso de sedativos e ocorrência de quedas e fratura de fêmur entre idosos em um ambulatório de geriatria

OBJECTIVE: To investigate the use of sedatives by older adults attending a private outpatient geriatric clinic in Belo Horizonte (MG), Brazil, and its association with falls and hip fractures. METHODS: Using a longitudinal design, the prevalence of benzodiazepine and nonbenzodiazepine ("z-drugs") intake by older adults was described and their association with the incidence of falls and fractures (30 days after the initial visit) was evaluated through logistic regression. RESULTS: A total of 7821 older adults were included in the study, most of them women (72.50%), with a mean age of 77.5 years and a mean Clinical-Functional Vulnerability Index (IVCF-20) score of 16.5. The overall prevalence of sedative use (any sedative) was 6.19%, with 4.48% benzodiazepines and 1.98% z-drugs. The most widely used sedatives were clonazepam (29.04%), zolpidem (28.65%), and alprazolam (23.44%). Falls were reported for 182 patients (2.33%), with a higher incidence among users of any sedatives (4.34; p = 0.002; OR = 1.94, adjusted for sex, age, and IVCF-20) and benzodiazepines (5.14%; p < 0.001; OR = 2.28) than among non-users (2.19%). Hip fractures occurred in 33 patients (0.42%), and again were more frequent among users of sedatives (1.03%; p = 0.032; OR = 2.57) and benzodiazepines (1.43%; p = 0.003; OR = 3.45) than among non-users (0.38%). CONCLUSIONS: The use of sedatives, especially benzodiazepines, is associated with an increased incidence of falls and hip fractures in older adults

METODOLOGIA: Trata-se de estudo longitudinal, no qual foi descrita a prevalência de uso de benzodiazepínicos e drogas Z entre idosos (60 anos ou mais) e avaliada sua associação com a incidência de queda e fratura (30 dias após consulta inicial) por meio de regressão logística. RESULTADOS: Foram incluídos no estudo 7821 idosos, com maioria feminina (72,50%), idade média de 77,5 anos e Índice de Vulnerabilidade Clínico Funcional (IVCF-20) médio de 16,5 pontos. A prevalência de uso de sedativos em geral foi de 6,19%, sendo 4,48% de benzodiazepínicos e 1,98% de drogas Z. Os medicamentos sedativos mais utilizados foram clonazepam (29,04%), zolpidem (28,65%) e alprazolam (23,44%). Relatou-se queda para 182 idosos (2,33%), com incidência maior entre usuários de sedativos (4,34; p = 0,002; OR = 1,94 ajustada por sexo, idade e IVCF-20) e de benzodiazepínicos (5,14%; p < 0,001; OR = 2,28) do que entre não usuários (2,19%). Identificou-se fratura de fêmur em 33 idosos (0,42%), sendo mais frequente entre usuários de sedativos (1,03%; p = 0,032; OR = 2,57) e de benzodiazepínicos (1,43%; p = 0,003; OR = 3,45) do que entre não usuários (0,38%). CONCLUSÃO: Concluiu-se que a incidência de quedas e fraturas de fêmur em idosos possui associação com o uso de medicamentos sedativos, em especial os benzodiazepínicos

Barriers and enablers to deprescribing benzodiazepines in older adults: elaborating an instrument and validating its content / Facilitadores e dificultadores do processo de desprescrição de benzodiazepínicos em idosos: elaboração de um instrumento e validação de seu conteúdo

OBJECTIVE: To elaborate and validate an instrument on barriers and enablers to deprescribing benzodiazepines in the patient's perspective. METHODS: This study was conducted in 3 stages: (1) a methodological stage, (2) a semi-structured pilot interview with 25 older adults undergoing clonazepam deprescribing, and (3) content validation with the Delphi technique. Content validation was performed by 50 specialists with degrees and/or experience with primary health care and/or health care of older adults, such as physicians, pharmacists, and nurses. For evaluating the obtained results, we analyzed the concordance of evaluations with the coefficient of content validity (CCV). We considered values equal to or higher than 0.8 as acceptable levels of concordance. RESULTS: The instrument was considered validated in the first round of evaluation, where all items obtained a CCV of more than 0.8 in the specialists' assessment. Nevertheless, they proposed improvements that were incorporated to the final version of the questionnaire. CONCLUSION: The instrument represents an important tool to be used by health care professionals for optimizing benzodiazepine deprescribing, with suitable levels of clarity and validity.

RESULTADOS: O instrumento foi considerado validado na primeira rodada de avaliação, em que todos os itens avaliados obtiveram CVC superior a 0,8 na avaliação dos especialistas. Entretanto, estes propuseram sugestões de melhorias que foram incorporadas na versão final do questionário. CONCLUSÃO: O instrumento apresenta-se como uma importante ferramenta a ser utilizada pelos profissionais de saúde para a otimização do processo de desprescrição de benzodiazepínicos, possuindo índice de clareza e de validade adequados.

Pattern evolution of antidepressants and benzodiazepines use in a cohort

ABSTRACT OBJECTIVE In recent decades there has been an increase in the use of antidepressants (AD) and a decrease in the use of benzodiazepines (BDZ). Prevalence, cumulative incidence, and factors associated with the incidence of AD and BDZ use in a Brazilian population were estimated in this article. METHODS Data were collected with a self-administered questionnaire in a cohort of employees from a university in Rio de Janeiro. The prevalence of the use of AD and BDZ was calculated for 1999 (4,030), 2001 (3,574), 2006-07 (3,058), and 2012 (2,933). The cumulative incidences of the use of AD and BDZ between 1999 and 2007 were estimated by the Poisson models with robust variance estimates. RESULTS In 1999, the prevalence of the use of AD and BDZ were 1.4% (95%CI: 1.1-1.8) and 4.7% (95%CI: 4.1-5.4), respectively; in 2012, they were 5.4% (95%CI: 5.5-6.2) and 6.8% (95%CI: 6.0-7.8). The incidence of use, between 1999 and 2007, was 4.9% (95%CI: 4.2-5.7) for AD and 8.3% (95%CI: 7.3-9.3) for BDZ. The incidences of AD and BDZ use were higher among women and participants with a positive General Health Questionnaire. CONCLUSION In this population, the increase in the use of AD was not accompanied by a decrease in the use of BDZ, showing the prescriptions for psychotropic medication do not follow the currently recommended guidelines for treatment of common mental health disorders.

Prevalence of and pathways to benzodiazepine use in Brazil: the role of depression, sleep, and sedentary lifestyle

Objective: This study aimed to determine the prevalence of benzodiazepine (BZD) use in Brazil and to investigate the direct and indirect effects of alcohol consumption, sedentary lifestyle (SL), depressive symptoms (DS), and sleep dissatisfaction (SD) on BZD use. Methods: The Second Brazilian Alcohol and Drugs Survey (II BNADS) used stratified cluster probabilistic sampling to select 4,607 individuals aged 14 years and older from the Brazilian household population. Results: The lifetime and 12-month prevalence of BZD use was 9.8 and 6.1%, respectively. Older participants (age 40 and older) and women had higher rates. Alcohol use disorder, DS, and SD were significantly more prevalent in BZD users. The parallel multiple mediator model showed a positive direct effect of alcohol consumption on BZD use, with significant positive indirect effects of SL, SD, and DS as simultaneous mediators leading to higher BZD intake. Other statistically significant indirect pathways were DS alone, SD alone, and all of the above except SL. Conclusion: The prevalence of BZD use in Brazil is high compared to that of other countries. Knowledge of the main risk factors and pathways to consumption can guide prevention initiatives and underlie the development of better tailored and effective treatment strategies.

¿Cómo afrontar un paciente con dependencia a benzodiacepinas en atención primaria? Estrategias para la deshabituación / How to face a patient with benzodiazepine dependence in primary health care? Strategies for withdrawal

Las benzodiacepinas son fármacos ampliamente utilizados en atención primaria de salud. Su uso prolongado se ha convertido en un problema relevante dadas las consecuencias médicas que ocasionan, especialmente en adultos mayores. Entre otras, estas son: dependencia, deterioro cognitivo y riesgo de caídas. Además, los médicos que trabajan en atención primaria cuentan con pocas herramientas para ayudar al paciente en su deshabituación. Se realizó una búsqueda y revisión de la mejor evidencia disponible sobre estrategias prácticas para el médico no especialista en adicciones, para evitar la dependencia al momento de la prescripción inicial y en el paciente con uso prolongado y probablemente dependiente. Se encontraron 10 revisiones sistemáticas relevantes que mostraron evidencia a favor del uso de estrategias multifacéticas en la prescripción, disminución progresiva, cartas y consejería estandarizadas, farmacoterapia y psicoterapia cognitiva conductual. Una estrategia sencilla, eficaz y duradera para prescribir benzodiacepinas es informar al paciente de la necesidad de reducir su consumo, dándole por escrito la pauta de retirada, señalando sus posibles efectos y su solución. Debido a la evidencia disponible, se propone un modelo integrado y escalonado para el manejo del paciente usuario de benzodiacepinas, desde su prescripción hasta su descontinuación.

Benzodiazepines are widely used in primary health care, and their prolonged use is an important problem given the medical consequences particularly in older adults, such as dependence, cognitive impairment, and risk of falls, among others. Primary care doctors generally have few tools to help with managing withdrawal from benzodiazepines. We conducted a review of the best available evidence on practical strategies to avoid dependence at the time of the initial prescription, and to help the patient with prolonged and probably dependent use. We found ten relevant systematic reviews showing evidence in favor of the use of multifaceted prescription strategies, gradual dose reduction, standardized letters, standardized counseling, pharmacotherapy and cognitive behavioral psychotherapy. For benzodiazepine withdrawal, a simple strategy that can be effective and long-lasting is to inform patients of the need to reduce consumption, giving them in writing the withdrawal guideline, indicating the possible effects of withdrawal and its solution. Given the available evidence, an integrated and step-by-step model is proposed for the management of the benzodiazepine user, from prescription to withdrawal.

Meta-analysis on the efficacy and tolerability of the augmentation of antidepressants with atypical antipsychotics in patients with major depressive disorder

We assessed the efficacy and tolerability of the augmentation of antidepressants (ATDs) with atypical antipsychotics (AAPs) to treat patients with major depressive disorder. A retrograde study to identify relevant patient data included databases of PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Database of Abstracts of Reviews of Effects. Data from 17 trials, involving 3807 participants, were identified. The remission rate (RR) and overall response rate (ORR) of adjunctive treatment with AAPs were significantly higher than placebo treatment: RR=1.90 (95%CI=1.61-2.23, z=7.74, P<0.00001) and ORR=1.68 (95%CI=1.45-1.94, z=7.07, P<0.00001). We found that the short-term (4 weeks) treatment [ORR=1.70 (95%CI=0.98-2.95, Z=1.89, P=0.06)] was significantly different from the long-term (6-12 weeks) treatment [ORR=1.68 (95%CI=1.45-1.94, z=7.07, P<0.00001)]. No significant difference in ORR was observed between groups with or without sedative drugs. The discontinuation rate due to adverse effects was higher for adjunctive treatment with AAPs: ORR=3.32 (95%CI=2.35-4.70, z=6.78, P<0.00001). These results demonstrate that the augmentation of ATDs with AAPs (olanzapine, quetiapine, aripiprazole, and risperidone) was more effective than a placebo in improving response and remission rates, although associated with a higher discontinuation rate due to adverse effects.

Consumo de benzodiazepinas en pacientes geriátricos del Consultorio 12, Policlínico Campo Florido / Benzodiazepine consumption of third age patients from the Campo Florido 12 consulting room

Se realizó una investigación descriptiva de corte transversal, en el Consultorio 12 perteneciente al área de salud del Policlínico Docente de Campo Florido del municipio Habana del Este, en el segundo semestre de 2007, con el objetivo de examinar el consumo de benzodiazepinas en pacientes de la tercera edad. Los principales resultados mostraron que fueron las mujeres las que más consumieron estos medicamentos, los ancianos más consumidores están en el grupo de edades de 60-64 años, siendo el diazepam, además, el más utilizado; en cuanto a la prescripción, los hombres siguieron en mayor medida las indicaciones médicas, lo que no se comportó igual en las féminas. Las indicaciones que predominaron fueron la ansiedad y el insomnio. Se concluye que la prescripción de psicofármacos en la población anciana constituye una práctica clínica habitual que merece atención

A cross-sectional and descriptive research was conducted in the 12 Consulting Room from the health area of "Campo Florido" Polyclinic from Habana del Este Municipality during the second semester of 2007 to examine the benzodiazepines consumption in third age patients. The main results demonstrated that there was predominance in female sex in the use of these drugs, elderlies with a great consumption aged 60-64, where the Diazepam was the more used; as regards the prescription, men followed in a greater measure the medical indications but not in females. Symptoms predominating were anxiety and sleeplessness. We conclude that psychotropic drugs in elderly population are a usual clinical practice deserving attention

O papel de mulheres idosas consumidoras de calmantes alopáticos na popularização do uso destes medicamentos / The role of elderly female consumers of allopathic tranquilizers in the popularization of the use of these medicines / El papel de mujeres adultas mayores consumidoras de calmantes alopáticos en la popularización del uso de estes medicamentos

O consumo de calmantes alopáticos (benzodiazepínicos) possui dimensão social e cultural, e não está restrito a uma relação entre médico e paciente. Objetivamos mostrar, portanto, que o consumo de calmantes é particularizado de acordo com os contextos social e cultural em que seus consumidores estão envolvidos. Buscamos então, utilizando abordagem qualitativa com entrevistas semi-estruturadas, as concepções sobre calmantes alopáticos de 18 mulheres idosas, pacientes psiquiátricas do Núcleo de Saúde Mental do Centro Saúde Escola da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (FMRP-USP), da cidade de Ribeirão Preto-SP, Brasil, consumidoras de benzodiazepínicos há mais de um ano. Concluímos que o consumo de calmantes está envolvido em uma rede de relações sociais, enredando vizinhos, parentes e amigos. As mulheres entrevistadas mostraram ter autonomia e conhecimento sobre o uso dos calmantes, sentindo-se capazes de utilizar, indicar, oferecer, emprestar, ou não, esses medicamentos, de acordo com suas concepções.

The consumption of allopathic tranquilizers (benzodiazepines) has social and cultural dimensions, not being restricted to a relation between physician and patient. Therefore, we aimed to show that the consumption of tranquilizers is particularized according to the social and cultural contexts their consumers are involved in. Using a qualitative approach with semistructured interviews, we search for conceptions about allopathic tranquilizers in 18 elderly women, psychiatric patients attended to in the Mental Health Centre of the Health Teaching Centre at the, University of São Paulo at Ribeirão Preto Medical School, (FMRP-USP), in the city of Ribeirão Preto (SP), Brazil, who were consumers of benzodiazepines for more than one year. We concluded that the consumption of tranquilizers is entangled in a network of social relations, including neighbors, relatives and friends. The interviewed women showed to have autonomy, feeling able to use, indicate, offer and lend, or not, these medicines, according to their conceptions.
