[Long-term benzodiazepine use in women at a daycare center for older people]

EPIDEMIA DE DROGAS PSIQUIÁTRICAS: TIPOLOGIAS DE USO NA SOCIEDADE DO CANSAÇO

Resumo: Este artigo tem por objetivo analisar o fenômeno da epidemia de uso de drogas psiquiátricas a partir da perspectiva do consumo cada vez mais disseminado e sua relação com a criação de subjetividades sociais que se constituem pela medicalização. Foram considerados dois diferentes contextos de uso que não necessariamente estão vinculados a diagnósticos. Em uma extremidade do fenômeno, identifica-se o consumo voltado para melhoria de desempenho em atividades competitivas de mercado, utilizando drogas como metilfenidato com a perspectiva de ultrapassar o desenvolvimento usual das práticas sociais e produtivas. Em outra extremidade, populações vulnerabilizadas que utilizam os psicotrópicos com o intuito de suportar experiências cotidianas de sofrimento que seriam intoleráveis de outra forma. A análise, apresentada na forma de ensaio, indicou um processo de uso acentuado de drogas psiquiátricas relacionado aos ideais de produtividade e desempenho ditados pelo padrão normativo da subjetividade neoliberal, o qual atinge particularmente as mulheres.

Assessment of dependence and anxiety among benzodiazepine users in a provincial municipality in Rio Grande do Sul, Brazil

INTRODUCTION

Benzodiazepines are among the most prescribed drugs for anxiety and one of the most used drug classes in the world and have a high potential for addiction. The objective of this study was to assess levels of dependence and anxiety among users of these drugs in the public health system.

METHODS

This was a cross-sectional, descriptive and quantitative study. Benzodiazepine users treated on the public health system were selected. Anxiety levels were assessed with the Hamilton Anxiety Scale and dependency with the Benzodiazepine Dependence Self-Report Questionnaire.

RESULTS

Benzodiazepine use was higher among women and in older age groups. Duration of benzodiazepine use was greater than 1 year for all respondents. The dependence assessment indicated that more than half of users were dependent on taking benzodiazepines and most had a severe degree of anxiety.

CONCLUSION

This study found evidence of prolonged and inappropriate use of benzodiazepines. It is necessary to educate users about the risks of these drugs and to develop strategies to rationalize use of these drugs by working with prescribers and dispensers.

Clinical and epidemiological analysis of hospitalizations of elderly due to poisoning and adverse effects of medications, Brazil from 2004 to 2008

The elderly are more susceptible to adverse drugs effects due to a variety of factors, such as excessive and concomitant use of several drugs, administration errors, physiological changes in the body that alter the pharmacodynamics and pharmacokinetics. In order to determine the main therapeutic classes involved in hospital admissions of elderly people due to intoxication and adverse drug effects, as well as major health problems related to these events, 9,793 hospitalizations of people aged 60 or over registered in the Hospital Information System of the Unified Health System (SIH-SUS) in the period of 2004 to 2008 were analyzed. Unspecified drugs, systemic antibiotics, psychotropics, psychoactives, antiepileptics, sedatives, hypnotics and antiparkinsonians accounted for 57% of the total of admissions analyzed. Injuries and falls were the main health problems related to intoxication and adverse drug effects. Hospitalizations due to injuries were associated with analgesic, antipyretic and antirheumatic non-opioid. Falls were associated with systemic antibiotics, contradicting studies which point out psychotropic drugs as the main drug involved in these events. The results reflect the growing trend of problems associated with drug use by elderly people. It was verified that the consumption profile alone is not sufficient to explain the concentration of cases of the major therapeutic classes. We suggest the adoption of more effective programs of pharmacovigilance, capable of intervening at different stages of drug use: prescribing, dispensing, marketing, administration and compliance.

Benzodiazepine use among adults residing in the urban settlements of Karachi, Pakistan: a cross sectional study

BACKGROUND

There are hardly any studies carried out in Pakistan on the usage of benzodiazepines at the level of community. This research was aimed to determine the frequency of benzodiazepine use, along with its associations with socio-demographic and clinical characteristics among community dwelling adults, residing in two urban settlements of Karachi, Pakistan.

METHODS

We performed a cross sectional study from August 2008 to December 2009, in 2 areas of Karachi, namely Garden and Sultanabad. We followed the systematic sampling strategy to randomly select the households, with an adult of either sex and of age 18 years or more. Data collection was carried out through interview, using a pre-tested questionnaire, with items on socio-demographic position, medical history and benzodiazepine use. Student's t-test and χ2 test was employed to determine the associations between socio-demographic and clinical characteristics, and their relationship with benzodiazepine use was determined using applied logistic regression.

RESULTS

The overall percentage of benzodiazepine consumption was estimated to be 14%. There were significantly more benzodiazepine users in the peri-urban Sultanabad community to the urban community of Garden (p-value = 0.001). The mean age (± SD) for users was 51.3 (± 15.6) years compared to 37.1 (± 14.4) years among non-users. Bromazepam was the most widely used benzodiazepine (29%); followed by diazepam, with a median duration on primary use being 144 weeks (IQR = 48-240). The adjusted logistic regression model revealed that increasing age, location, female sex, unemployment and psychiatric consultation were associated with increased likelihood of benzodiazepine use.

CONCLUSION

We believe the unregulated over-the-counter sales of benzodiazepines and social conditions might be playing a role in this high consumption of benzodiazepines in the community.

A population based study on health conditions associated with the use of benzodiazepines among older adults (The Bambuí Health and Aging Study)

The aim of this study was to assess the health conditions and use of health services among elderly users of benzodiazepines. The study was carried out in the city of Bambuí in Minas Gerais State, Brazil. Of 1,742 inhabitants aged over 60, 1,419 participated in the study. Information about benzodiazepine and the use of other medications was obtained by means of interviews and checking medication packaging. After adjustments for confounding variables, benzodiazepine remained significantly associated with poorer self reported health (prevalence ratio = 1.94 and 2.04 for reasonable and bad/very bad health, respectively), common mental disorders (1.33), myocardial infarction (1.42), number of doctor visits in the previous 12 months (1.90 and 2.24 for 2-3 and 4+ visits, respectively) and concomitant use of other medications (1.84 and 1.83 for 2-4 and 5+ medications). The results showed that the factors associated with the use of benzodiazepine were similar to those observed in the elderly in higher income countries. The concomitant use of benzodiazepines and two or more medications was highly prevalent (59.5%), characterizing a situation of risk, which deserves attention as a public health problem.

Medicalização de mulheres idosas e interação com consumo de calmantes

Investigamos neste estudo a interação entre gênero, envelhecimento e consumo particularizado de calmantes (benzodiazepínicos), procurando entender como, dentro do processo de medicalização da sociedade, essa interação interfere nos modos de utilizar e nas concepções sobre os calmantes e como são (re)significados pelas consumidoras. No estudo, foram realizadas entrevistas semi-estruturadas com 18 mulheres idosas, que a partir de uma análise qualitativa foram interpretadas, à luz dos enfoques teóricos de gênero, transição de idades e medicalização. Essas mulheres eram pertencentes a classes populares da cidade de Ribeirão Preto-SP, pacientes psiquiátricas do serviço público ambulatorial do Núcleo de Saúde Mental, vinculado ao Centro de Saúde Escola da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (FMRP-USP). Observamos que o consumo de calmantes é intensificado entre as mulheres idosas, que passam a tratar conflitos e questões cotidianas por meio do uso de medicamentos. As mulheres idosas, com experiência de freqüência dos serviços de saúde, entre eles os psiquiátricos, durante vários anos, conseguem incorporar conhecimentos e experiências sobre o uso dos calmantes, promovendo a sua difusão no meio social.

Habilidades cognitivas e uso de benzodiazepínicos em idosas institucionalizadas

OBJETIVO: O objetivo desta pesquisa foi verificar as habilidades cognitivas em idosas usuárias de benzodiazepínicos e as idosas não-usuárias deste tipo de medicação. Participaram do estudo 123 idosas institucionalizadas. MÉTODO: O delineamento foi de um estudo quantitativo e de um transversal. Os instrumentos utilizados foram: ficha de dados sociodemográficos, breve entrevista internacional de neuropsiquiatria modificada, mini-exame do estado mental, escala de depressão geriátrica, span de números, teste de fluência verbal (categoria animal) e teste de evocação seletiva livre e com pistas (Buschke). RESULTADOS: A idade variou entre 60 e 101 anos, com a média de 79,73 anos (DP = 9,56). Não houve diferença em relação à idade ou aos anos em que residência na instituição asilar (p = 0,846). O tempo mínimo foi de 1 ano e o máximo, de 26 anos, a média ficou em 4,02 anos (DP = 4,38). O tempo médio de estudo foi de 5,98 anos (DP = 4,17), 80,5% sabem ler e 79,7% sabem escrever. CONCLUSÃO: Não foram encontradas associações significativas entre as habilidades cognitivas em idosas usuárias de benzodiazepínicos e as não-usuárias.

Prevalence and sociodemographic characteristics associated with benzodiazepines use among community dwelling older adults: the Bambuí Health and Aging Study (BHAS)

OBJECTIVES: To assess the prevalence and sociodemographic characteristics associated with benzodiazepine use among community-dwelling older adults. METHOD: 1606 subjects, aged > 60 years, corresponding to 92% of the residents of Bambuí city, participated in this study. The information about medication use was obtained by means of a standard interview and the review of medication packaging. Substances were classified using the Anatomical Therapeutic Chemical Index. RESULTS: The prevalence of benzodiazepine current use was 21.7% (26.7% among females and 14.0% among males). From these, 68.7% had been taking the medication for over one year, 31.3% for over five years and 53.2% were using long half-life benzodiazepines. The medication most frequently used was bromazepam (35.6%), followed by diazepam (22.5%), clonazepam (12.6%) and lorazepam (7.8%). After adjustment for confounders, female gender (RP = 1.93; CI95% = 1.51-2.46) was the only sociodemographic characteristic found to be independently associated with substance consumption. CONCLUSIONS: The prevalence of benzodiazepine use in the study population was high, but within the variation observed in developed countries. Chronic use of benzodiazepines and long half-life medications predominated.

Automedicação em idosos na cidade de Salgueiro-PE

OBJETIVOS: identificar os determinantes associados ao perfil da automedicação na população de idosos de 60 anos e mais, no município de Salgueiro/Pernambuco/Brasil. MÉTODO: Estudo de corte transversal realizado na zona urbana no município de Salgueiro - PE. Entre 01/05 a 10/06/2004, foram aplicados questionários em uma amostra de 355 indivíduos da população de 60 anos e mais. Os dados foram processados e analisados no EPIINFO 6.04 após digitação em dupla entrada e validação. RESULTADOS: 44,9% dos entrevistados encontravam-se na faixa etária de 60-70 anos, 247 (69,8%) eram do sexo feminino, 188 (53,1%) eram analfabetos e 145 (40,7%) tinham o primeiro grau incompleto, sendo 276 (77,7%) aposentados. Entre os que faziam uso de medicamentos sem receita médica houve predomínio de analgésicos (30%) e antipiréticos (29%). Entre os motivos mais freqüentes apresentados, e que levavam os indivíduos a tomar remédios por conta própria, a dor tem o maior índice (38,3%), seguida de febre (24,4%), diarréia (8,0%), pressão alta (8,0%) e tosse (5,2%). Houve associação entre a ausência de atividade física e automedicação (x² =14,44, p=0,001). CONCLUSÃO: existe grande prevalência da automedicação neste grupo, sendo os analgésicos e os antipiréticos os mais utilizados; a dor é o sintoma que mais leva à automedicação; os idosos sedentários se automedicam mais que os praticantes de atividade física.

[Prevalence, associated factors, and misuse of medication in the elderly: a review]

Most elderly people use at least one medication, and about one-third use more than five drugs simultaneously. Many patients have no access to the drugs they most need, and others use unnecessary or dangerous drugs. The mean number of drugs used by the elderly, as quoted in different studies, varies from 2 to 5. Significant predictors for such misuse of medication are older age, female gender, precarious health conditions, and depression. Cardiovascular drugs, anti-rheumatics, and analgesics are the most frequently consumed therapeutic classes. Multiple use, prescription of contraindicated drugs, redundant use, and inadequate training of the health care team are associated with adverse drug effects and interactions. Better quality of prescriptions and research on drug use can bring benefits to people aged 60 years or older.

[A literature review on pharmacists' interventions in the use of medication by elderly patients]

The total proportional geriatric population in Brazil is projected to increase from 9.05% in 1999 to approximately 13% in 2020. Non-communicable diseases are common in this age group, and medication is used frequently. Inadequate prescription and improper use of drugs can produce undesirable outcomes, leading to avoidable hospitalization and increasing health care costs. The objective of this paper was to conduct a literature review of pharmacists' interventions and their influence on use of medication by elderly patients, based on five databases from 1970 to 1999. The sample consisted of 76 studies, of which 15 were analyzed and discussed. Research on this subject is scarce, and limited to developed countries. In general, the interventions presented favorable outcomes. Most actions were limited to counseling patients and their physicians, and there was a lack of interventions to adjust the medication to the user.
