Prevalence of non-communicable chronic diseases: arterial hypertension, diabetes mellitus, and associated risk factors in long-lived elderly people

OBJECTIVE

To identify the prevalence of non-communicable chronic diseases: arterial hypertension, diabetes mellitus, and associated risk factors in long-lived elderly people from three Brazilian regions.

METHODS

This is a multicenter, cross-sectional, and comparative study conducted with elderly people aged 80 years or older.

RESULTS

Higher prevalence of arterial hypertension were observed among those who use polypharmacy (75.7%), among elderly people aged between 80 and 84 years (33.9%), as well as in elderly people who are overweight (78.2%). The prevalence of diabetes was 24% (RP: 0.76; 95% CI: 0.59-0.98) lower among women compared to men and 2.15 times higher among those who use five or more medications (RP: 2.15; 95% CI: 1.63-2.85).

CONCLUSIONS

In our sample, polypharmacy, body weight, and gender determine the prevalence of non-communicable chronic diseases: arterial hypertension and diabetes mellitus in long-lived elderly people.

Irrational use of alendronate sodium by the elderly

Introduction: The effectiveness and safety of alendronate sodium are dependent on patient adherence to very specific guidelines regarding use. This study aims to estimate the rational use of alendronate sodium in the elderly. Methods: This is a cross-sectional study carried out with a structured questionnaire containing form of use and occurrence of adverse events related to alendronate sodium. The patients were recruited in their own homes. Rational use was considered as being the participants who: a) took the tablet in the morning; b) were fasting; c) waited at least 30 minutes before eating; d) ingested with a full glass of water; e) ingested the whole tablet; f) and remained in the orthostatic position for at least 30 minutes after use. Additionally, the odds ratio (OR) was used to analyze the association between the irrational use of alendronate sodium and the independent variables. Results and Discussion: Of the 248 participants in the study, most of the participants administered the medication in the morning (95.2%), with fasting (89.1%), waited at least 30 minutes to eat the first meal of the day (87.9%), and were in the orthostatic position until the time of the first meal (78.6%), but less than half ingested the tablet with a full glass of water (43.6%). Rational use of the medication was observed in only 30.7% of the participants. Regarding possible adverse events, 13.3% of the participants reported some event. Among the most prevalent were dry cough (6.5%), stomach pain (5.2%) and some throat discomfort (4.8%). The irrational use of this medication is associated with age and education level. Conclusion: The prevalence of irrational use of alendronate sodium in the elderly is high, and this use is associated with patients’ sociodemographic factors.

Objectively Measured Physical Activity and Polypharmacy Among Brazilian Community-Dwelling Older Adults

BACKGROUND

Previous observations regarding association between physical activity (PA) and use of medicines among older adults are derived from self-reported PA. This study aimed to evaluate the association between objectively measured PA and polypharmacy among older adults with multimorbidity in Southern Brazil.

METHODS

This study included 875 noninstitutionalized older people, aged ≥60 years. Prescribed medicines used in the 15 days prior to the interview, socioeconomic data, and the presence of comorbidities were self-reported. Accelerometers were used to evaluate PA following the interview.

RESULTS

Prevalence of polypharmacy (≥5 medicines) was 38.3% (95% confidence interval, 35.0-41.5); those belonging to the lowest tertile of PA used more medicines. The authors observed a significant inverse association for polypharmacy between men belonging to the second and third tertiles of PA for objectively measured overall PA and light PA compared with the most inactive tertile. For women, the association between PA and polypharmacy was significant for overall, light, and moderate to vigorous PA only in the third tertile.

CONCLUSIONS

Overall, light and moderate to vigorous PA were inversely associated to polypharmacy and differed by gender. Promotion of PA in older adults may be an effective intervention to reduce the number of medicines used independent of the number of comorbidities.

Polypharmacy, socioeconomic indicators and number of diseases: results from ELSA-Brasil

ABSTRACT: Objective: To estimate the prevalence of polypharmacy, describe the pharmacotherapeutic classes used, and investigate whether polypharmacy is associated with demographic and socioeconomic indicators, regardless of the number of diseases, among participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline (2008-2010). Method: In this analysis, 14,523 adults and elderly (35-74 years) participated. Polypharmacy was characterized as regular use of five or more medicines. The demographic and socioeconomic indicators analyzed were: gender, age, education level, per capita family income, and access to private health insurance. The independent association between demographic and economic indicators and polypharmacy was estimated by binary logistic regression. Results: The prevalence of polypharmacy was 11.7%. The most used drugs were those with action on the cardiovascular system. After adjustments, including by number of diseases, the chances of being on polypharmacy treatment were significantly higher among women, older participants and those with greatest number of diseases. Individuals without health insurance had lower chance to be under polypharmacy, as well as those with lower income. Conclusion: The occurrence of polypharmacy among ELSA-Brasil baseline participants was mainly due to drugs for the treatment of chronic diseases. The relation between polypharmacy and the female gender, as well as its association with old age, are in consonance with the results obtained in other studies. Despite the absence of an association between polypharmacy and education level, the income and health insurance results reinforce the existence of social inequalities regarding drug use.

[Polypharmacy and associated factors in elderly diabetic]

OBJECTIVES

The objective of this study was to evaluate factors related to polypharmacy and the use of potentially inappropriate medications (PIM) in elderly patients with diabetes.

METHODS

We studied 127 elderly diagnosed with type 2 diabetes, 41 males (age = 69.9 ± 6.9 years) and 86 women (age = 71.1 ± 7.7 years). For evaluation of health conditions, medication use, polypharmacy and associated factors, we used the questionnaire adapted from Morais. The drugs were classified according to the Anatomical Therapeutic-Chemical Classification System, and for identification of MPI, we adopted the criteria of Beers-Fick and PRISCUS. For data analysis, we used descriptive statistics and chi-square and Fisher Exact tests.

RESULTS

In this population, 100% of elderly using drugs. The average consumption was 5.8 per individual drug, varying from two to 14, and the prevalence of polypharmacy was 85%. Among the factors studied, only the retirement showed a statistically significant association (p <0.05) with polypharmacy. The most prevalent diseases were hypertension (92.8%), heart problems (70.8%), circulatory (40.8%) and musculoskeletal problems (44.5%). Of drugs used by the elderly, 12 of them were considered potentially inappropriate and 47.2% of the study subjects make use of these medicines regularly.

CONCLUSIONS

Thus, this study urges new thinking pharmaceutical assistance, as a practical view in full perspective and not meant only as purchasing and dispensing drugs.

Polypharmacy among the elderly: a population-based study

Objective:

To investigate polypharmacy among the elderly living in the urban area of Florianopolis, in the state of Santa Catarina, Brazil, estimating the prevalence and associated factors.

Methods:

This is a cross-sectional population-based study with a sample of 1,705 individuals aged 60 years old or older, between 2009 and 2010. The dependent variable was polypharmacy (defined as "use of five or more medications"). The following exploratory variables were utilized: sociodemographic data, use of health services and self-rated health status. Prevalence ratios (PR) were estimated by multivariate analysis using the Poisson regression.

Results:

The mean for the medications used by the elderly population was 3.8 (ranging from 0 to 28). The prevalence of polypharmacy was 32%, with 95% confidence interval (95% CI) 29.8 - 34.3. The characteristics presenting a positive association with polypharmacy were: female gender (PR = 1.27; 95%CI 1.03 - 1.57), increasing age (PR = 1.38; 95% CI 1.08 - 1.77), negative self-rated health status (PR = 1.99; 95% CI 1.59 - 2.48) and medical appointments in the 3 months prior to the interview (PR = 1.89; 95% CI 1.53 - 2.32). The groups of medication most utilized by the elderly individuals in polypharmacy were those indicated for the cardiovascular system, digestive tract and metabolism, as well as the nervous system.

Conclusion:

The pattern of medication use among this elderly population is within the national average. The prevalence of polypharmacy and the characteristics associated with it were similar to those found in other regions of Brazil.

Evaluation of diet quality of the elderly and associated factors

BACKGROUND

Observational studies suggest healthy dietary patterns are associated with risk reduction and better control of various chronic diseases. However, few Brazilian studies have focused on evaluating the quality of the elderly diet and its relationship with diseases. This study aimed to estimate the association between diet quality and socioeconomic factors, health and nutrition of the elderly.

METHODS

This is a cross-sectional population-based study whose target population were non-institutionalized elderly residents in the city of Viçosa, Brazil. Anthropometric, socioeconomic, health conditions, lifestyle and food consumption variables were obtained from a semi-structured questionnaire. The quality of the diet was assessed by the revised Healthy Eating Index classified into tertiles, considering the first tertile as "Poor diet quality," the second as 'Intermediate diet quality' and the third as "Better diet quality." To identify factors independently associated with diet quality model, the works used multinomial logistic regression.

RESULTS

In the results of the multivariate analysis, the factors independently associated with "better diet quality" included female gender, higher education, history of one to five medical visits in the past year, history of diabetes mellitus, dyslipidemia and the use of polypharmacy.

DISCUSSION

Our results show that most seniors need to improve the quality of their diet and those of male gender with no or little education, and those who do not seek medical services constitute the group that needs attention concerning the measures to improve the quality of their diet.

Prevalence of and factors associated with polypharmacy among elderly persons resident in the community

Abstract Objective: to verify the prevalence of and factors associated with polypharmacy among elderly residents of the city of Cuiabá, in the state of Mato Grosso. Method: a cross-sectional study of 573 people aged 60 and over was performed. Polypharmacy was defined as the use of five or more medications. To investigate the association between polypharmacy and sociodemographic variables, health and access to medication, the Mantel Haenszel chi square test was used in bivariate analysis and Poisson regression was used in multivariate analysis. The significance level adopted was 5%. Result: the prevalence of polypharmacy was 10.30%. Statistically significant associations were found between polypharmacy and living with others, describing suffering from circulatory, endocrine, nutritional and digestive tract diseases, and referring to financial difficulties for the purchase of medicines. Conclusion: some social and health condition factors play an important role in the use of multiple medications among the elderly.

Polypharmacy and Polymorbidity in Older Adults in Brazil: a public health challenge

OBJECTIVE

To analyze variations in the prevalence of chronic use of medicines by older adults in Brazil according to its possible association with the most prevalent chronic diseases and demographic and health factors, and to identify risk factors for polypharmacy.

METHODS

A study based on data from the National Survey on Access, Use and Promotion of Rational Use of Medicines (PNAUM), a cross-sectional, population-based survey with probability sampling in Brazilian urban areas. The independent variable was the number of chronic-use medicines taken by older adults, linked to eight chronic diseases investigated. The intervening variables were gender, age group, marital status, level of education, socioeconomic status, Brazilian region, body mass index, smoking, self-perceived health, hospitalization in the previous year and having health insurance, besides the investigated chronic diseases. A multivariable analysis identified risk factors for polypharmacy.

RESULTS

Prevalence of at least one chronic-use medicines among older adults was 93.0%. Of the total number of older adults, 18.0% used at least five medications (polypharmacy). Polypharmacy was higher among the oldest individuals (20.0%), in the South region (25.0%), in those with poor self-perceived health (35.0%), in obese individuals (26.0%), in those with reported health insurance (23.0%) or hospitalization in the previous year (31.0%), and among those who reported any of the investigated diseases, particularly diabetes (36.0%) and heart diseases (43.0%). The variables remaining in the final risk model for polypharmacy were age, region, perceived health, health insurance, hospitalization in the previous year and all investigated diseases except stroke.

CONCLUSIONS

Older adults with specific diseases have risk factors for polypharmacy modifiable by actions aimed at the rational use of medicines. With the current population aging and successful drug access policy, the trend is an increase in drug use by older adults, which should feature as a priority in the planning agenda of the Brazilian Unified Health System (SUS).

OBJETIVO

Analisar as variações da prevalência do uso crônico de medicamentos por idosos no Brasil segundo sua possível associação com as doenças crônicas mais prevalentes, fatores sociodemográficos e de saúde, e identificar fatores de risco para polifarmácia.

MÉTODOS

Estudo com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos, de caráter transversal e amostra probabilística populacional em municípios brasileiros urbanos. A variável independente foi o número de medicamentos de uso crônico por idosos, vinculados às oito doenças crônicas investigadas. As variáveis intervenientes foram sexo, faixa etária, situação conjugal, escolaridade, nível socioeconômico, região do País, índice de massa corporal, hábito de fumar, percepção da própria saúde, internação no último ano e posse de plano de saúde privado, além das doenças crônicas referidas. Uma análise multivariável identificou os fatores de risco para polifarmácia.

RESULTADOS

A prevalência de pelo menos um medicamento de uso crônico entre idosos foi de 93,0%. Do total de idosos, 18,0% utilizavam pelo menos cinco medicamentos (polifarmácia). A polifarmácia foi maior entre os mais idosos (20,0%), na região Sul (25,0%), nos que avaliaram a própria saúde como ruim (35,0%), nos obesos (26,0%), nos que referiram ter plano de saúde (23,0%) ou internação no último ano (31,0%) e entre os que referiram qualquer uma das doenças investigadas, particularmente diabetes (36,0%) e doenças cardíacas (43,0%). No modelo final de risco para polifarmácia permaneceram idade, região, percepção de saúde, posse de plano de saúde, internação no último ano e todas as doenças investigadas exceto acidente vascular cerebral.

CONCLUSÕES

Idosos com doenças específicas têm fatores de risco para polifarmácia modificáveis por ações que visem o uso racional de medicamentos. Com o envelhecimento populacional em curso e a política exitosa de acesso a medicamentos, a tendência é aumentar a utilização de medicamentos por idosos, que deve ser prioridade na agenda de planejamento do Sistema Único de Saúde.

Diabetes em idosos: uso de medicamentos e risco de interação medicamentosa

Resumo Caracterizar o perfil sociodemográfico e de saúde dos idosos segundo diabetes referido, avaliar o conhecimento e a prática quanto às opções de tratamento, bem como descrever o uso de medicamentos e potenciais riscos de interação medicamentosa (IM) neste subgrupo. Estudo transversal com 1.517 idosos de Campinas em 2008. Estimaram-se as prevalências de diabetes e verificaram-se as associações pelo teste de Rao-Scott. As potenciais IM foram avaliadas pela base de dados Micromedex®. A prevalência de diabetes referida pelos idosos foi de 21,7% sem diferença significativa entre os sexos. Verificou-se maior percentual de idosos diabéticos com 70 anos ou mais, com menor escolaridade, renda familiar per capita inferior a 1 salário mínimo e que não realizavam atividade ocupacional. O número médio de medicamentos foi de 3,9 nos 3 dias anteriores. Identificaram-se 413 possíveis interações, sendo que 53,1%, 7,8% e 7,2% dos idosos apresentaram risco de IM moderadas, menores e graves, respectivamente. Ressalta-se a importância da adoção de dieta saudável e prática de atividade física para redução do peso, controle da doença e de complicações. Evidencia-se a necessidade de atenção ao risco potencial das IM e o uso de medicamentos inapropriados ao idoso.

[Drug prescriptions of patients treated in a geriatric outpatient ward of a university hospital: a descriptive cross-sectional study]

The scope of this study was to evaluate drug prescriptions for elderly patients in the geriatric outpatient ward of a hospital. A cross-sectional descriptive study was conducted in a university hospital, with the application of a questionnaire. Patients aged >60 years were interviewed about their drug prescriptions and a total of 208 patients were interviewed. The average number of drugs used per person was 3.8 and the drugs most used were for the cardiovascular system (37%). 406 potential interactions were identified in 140 patients (67.3%), and duplicate therapy was found in two prescriptions. The potentially inappropriate drug most used for the elderly was nifedipine (2.4%). Data from this study support the relevance of the issue of drug use among the elderly, thus reinforcing the importance of the evaluation of the process of the prescription of drugs for this population.

"Positive to Negative" Dix-Hallpike test and Benign Paroxysmal Positional Vertigo recurrence in elderly undergoing Canalith Repositioning Maneuver and Vestibular Rehabilitation

Introduction Benign Paroxysmal Positional Vertigo is the most common cause of dizziness in elderly people. Recent studies have shown that the elderly present higher Benign Paroxysmal Positional Vertigo recurrence and that vertiginous symptomatology remission varies according to comorbidities and the therapeutic techniques applied.

Objective To assess the short-term effectiveness of Vestibular Rehabilitation in addition to Canalith Repositioning Maneuver on positive to negative Dix-Hallpike test, on recurrence and number of maneuvers to achieve a negative test in elderly patients with chronic Benign Paroxysmal Positional Vertigo.

Methods In this randomized controlled trial, 7 older adults (median age: 69 years, range 65–78) underwent Canalith Repositioning Maneuver and Vestibular Rehabilitation for thirteen weeks. Seven older adults (median age: 73 years, range 65–76) in the control group received only Canalith Repositioning Maneuver. The participants were assessed at baseline (T0), one (T1), five (T5), nine (T9), and thirteen weeks (T13). We assessed the differences between the groups by Mann-Whitney and Fisher exact tests, and used the Friedman and Wilcoxon tests to determine the intragroup differences.

Results No significant differences were found between groups for the positive to negative Dix-Hallpike test, recurrence, and number of maneuvers to achieve a negative test. The number of maneuvers to achieve negative Dix-Hallpike test was lower in intragroup comparisons in the experimental group.

Conclusion The findings suggest that additional Vestibular Rehabilitation did not influence the positive to negative Dix-Hallpike test, recurrence, or number of maneuvers to achieve a negative test in elderly patients with chronic Benign Paroxysmal Positional Vertigo.

Medication regimen complexity in adults and the elderly in a primary healthcare setting: determination of high and low complexities

Background:

The complexity of a medication regimen is related to the multiple characteristics of the prescribed regimen and can negatively influence the health outcomes of patients.

Objective:

To propose cut-off points in the complexity of pharmacotherapy to distinguish between patients with low and high complexities seen in a primary health care (PHC) setting to enable prioritization of patient management.

Methods:

This is a cross-sectional study, which included 517 adult and elderly patients, analyzing different cut-off points to define the strata of low and high pharmacotherapy complexities based on percentiles of the population evaluated. Data collection began with the solicitation of prescriptions, followed by a questionnaire that was administered by an interviewer. The complexity of a medication regimen was estimated from the Medication Regimen Complexity Index (MRCI). High complexity pharmacotherapy scores were analyzed from patient profiles, the use of health services, and pharmacotherapy. The criteria for subject inclusion in the sample population were as follows: inhabitant of the area covered by the municipality, 18 years or older, and being prescribed at least one drug during the collection period. Exclusion criteria at the time of collection were the use of any medication whose prescription was not available. All medications were accessed through the Primary Healthcare Service (PHS).

Results:

The median total pharmacotherapy complexity score was 8.5. High MRCI scores were correlated with age, medications taken with in the Brazilian PHS, having at least one potential drug-related problem, receiving up to eight years of schooling, number of medications and polypharmacy (five or more medicines), number of medical conditions, number of medical appointments, and number of cardiovascular diseases and endocrine metabolic diseases. We suggest different complexity tracks according to age (e.g., adult or elderly) that consider the pharmacotherapy and population coverage characteristics as high complexity limits. For the elderly patients, the tracks were as follows: MRCI≥25.4, MRCI≥20.9, MRCI≥17.5, MRCI≥15.7, MRCI≥14.0, and MRCI≥13.0. For adult patients, the limits of high complexity were MRCI≥25.1; MRCI ≥ 23.8; MRCI≥21.0; MRCI≥17.0; MRCI≥16.5; and MRCI≥15.5.

Conclusion:

The medication regimen complexity is associated with the patient’s illness profile and problems with the use of drugs; therefore, the proposed scores can be useful in prioritizing patients for clinical care by pharmacists and other health professionals.

Uso de anti-inflamatórios e analgésicos por uma população de idosos atendida na Estratégia Saúde da Família

ResumoEste estudo objetivou analisar a prevalência do uso de anti-inflamatórios e analgésicos em idosos da Estratégia Saúde da Família de Porto Alegre-RS, bem como investigar fatores associados: dados sociodemográficos e de saúde; uso contínuo ou se necessário da medicação; indicação médica ou automedicação. A coleta de dados ocorreu entre março de 2011 e dezembro de 2012. Os agentes de saúde comunitários aplicaram um questionário com dados sociodemográficos, de saúde e uso de medicamentos. Foram estudados os anti-inflamatórios não esteroidais, glicocorticoides, analgésicos não opioides e opioides de uso oral. Foram incluídos 758 idosos e o uso de anti-inflamatórios e analgésicos era feito por 28,8%. O paracetamol e o ibuprofeno foram os mais utilizados. No que diz respeito à autopercepção de saúde, quanto pior a saúde relatada, maior o uso da terapêutica (p<0,001). A doença hepática e artrose/artrite/reumatismo mostraram estar associadas ao uso de anti-inflamatórios e analgésicos (p<0,001). A prevalência de uso de anti-inflamatórios e analgésicos foi considerada moderada quando comparada a estudos prévios (28,8%). Além disso, a maioria dos idosos fazia uso desses medicamentos quando era preciso, provavelmente porque sentia dores leves a moderadas, não sendo necessário o uso contínuo da medicação ou também por sofrer com os efeitos adversos desses medicamentos, optando por usá-los esporadicamente.

Fatores associados a não adesão medicamentosa entre idosos de um ambulatório filantrópico do Espírito Santo

OBJETIVOS: Estimar a frequência da não adesão ao tratamento medicamentoso entre idosos acompanhados ambulatorialmente, bem como analisar seus fatores associados. METODOLOGIA: Foi conduzido estudo transversal com 263 idosos atendidos no ambulatório de especialidades médicas de um hospital filantrópico, localizado no município de Vitória-ES. Foi realizada entrevista utilizando roteiro estruturado em três blocos que contemplavam questões sociodemográficas, condições de saúde e estilo de vida e medicamentos em uso. Para verificar a não adesão ao tratamento medicamentoso, foi aplicado o instrumento de Medida de Adesão Terapêutica (MAT). Os dados foram analisados por meio do teste Qui-quadrado para variáveis categóricas. Foram consideradas significativas as variáveis com valor de p<0,05 no modelo final de regressão múltipla de Poisson. RESULTADOS: Os resultados mostraram uma frequência de não adesão ao tratamento medicamentoso de 26,7% da amostra. A não adesão ao tratamento medicamentoso nessa população se mostrou positivamente associada à ausência de vínculo empregatício anterior a aposentadoria (RP=1,12; p<0,010); presença de declínio cognitivo (RP=1,13; p<0,010) e hábitos alimentares inadequados (RP=1,12; p<0,005). CONCLUSÃO: Com o estudo, foi possível identificar os fatores associados à não adesão medicamentosa nos idosos investigados e assim contribuir para o conhecimento do perfil sociodemográfico, condições de saúde e estilo de vida e características relacionadas à utilização de medicamentos por parte dessa população.

Testes de equilíbrio e mobilidade funcional na predição e prevenção de riscos de quedas em idosos

INTRODUÇÃO: A prevenção da ocorrência de quedas em idosos é um desafio para os profissionais da área da saúde. Um dos aspectos mais relevantes para tal prevenção é a detecção precoce de fatores de risco para quedas. Dentre estes, destaca-se o declínio do equilíbrio e da mobilidade funcional. OBJETIVOS: Avaliar a ocorrência de quedas e seus fatores associados e identificar os pontos de corte de testes de equilíbrio e mobilidade funcional mais adequados para identificar idosos ativos na comunidade com risco de quedas. METODOLOGIA: Estudo transversal composto por 127 idosos ativos na comunidade de Itabira-MG, avaliados quanto às características clínicas e sociodemográficas e ao equilíbrio e mobilidade funcional testes sentado para de pé, semi-tandem, step teste e velocidade da marcha de seis metros. RESULTADOS: A prevalência de quedas no ano anterior foi 25,2%, sendo 8,6% para quedas recorrentes. A ocorrência de quedas apresentou associação apenas com a variável "gênero", sendo maior a chance de cair entre as mulheres. Os pontos de corte para os testes sentado para de pé, step teste e velocidade da marcha foram 8,5 segundos, 7,5 segundos e 0,98 m/s, respectivamente. CONCLUSÃO: Os resultados demonstraram ser importante adequar os pontos de corte dos testes de equilíbrio e mobilidade ao perfil da população avaliada. Sem essa adequação, os testes têm sua sensibilidade e especificidade comprometidas na identificação de idosos com risco de cair.

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

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

Uso de medicamentos potencialmente inapropriados por idosos do Município de São Paulo, Brasil: Estudo SABE

Alguns medicamentos são considerados impróprios para o idoso, devido a alterações na farmacocinética e farmacodinâmica, por falta de eficácia terapêutica ou por um risco aumentado de efeitos adversos superando seus benefícios. Verificou-se a prevalência do uso de medicamentos potencialmente inapropriados, segundo os critérios de Beers, por idosos do Município de São Paulo, Brasil, participantes do Estudo SABE. Trata-se de um estudo transversal, de base populacional, cuja amostra de 1.254 indivíduos com 60 anos ou mais representava a população idosa do município no ano de 2006. Verificou-se a prevalência de 28% de uso de medicamentos potencialmente inapropriados. No modelo de regressão logística múltipla, as variáveis associadas ao uso foram uso de cinco medicamentos ou mais (p = 0,001), presença de duas ou mais doenças (p = 0,011) e sexo feminino (p = 0,007). Identificou-se o uso de 36 medicamentos potencialmente inapropriados, a maioria de venda sob prescrição. São necessários critérios específicos para a população brasileira e ampla divulgação da farmacologia clínica do idoso. Protocolos ou softwares para prescrição também podem auxiliar a prescrição racional para esse grupo.

Epidemiology of medication use among the elderly in an urban area of Northeastern Brazil

OBJECTIVE

To analyze medication use and associated factors among the elderly.

METHODS

A population-based cross-sectional study was carried out with a sample of 400 elderly people aged over 60 living in the urban area covered by the Family Health Strategy program in Recife, Northeastern Brazil in 2009. Individuals were selected by systematic random sampling and household data were collected. Demographic, socio-economic, lifestyle factors including nutrition practices and health variables were evaluated. Medication use was the independent variable. Univariate and multivariate statistical analysis were performed.

RESULTS

The prevalence of medication use was 85.5%. Polypharmacy (> 5 drugs) occurred in 11% of cases. Of the 951 drugs reported, 98.2% were prescribed by doctors and 21.6% were considered unsafe for the elderly. The most commonly prescribed groups were: cardiovascular drugs (42.9%), central nervous system agents (20.2%) and drugs with an effect on the digestive tract and metabolism (17.3%). The use of polypharmacy was associated with education (p = 0.008), self-reported health (p = 0.012), self-reported chronic disease (p = 0.000) and the number of doctor appointments per year (0.000).

CONCLUSIONS

The results of this study indicate a high proportion of medication use among the elderly, including of those considered unsuitable, and inequality among groups of elderly individuals regarding the use of medication, when education, number of doctor appointments and self-reported health are considered.

Perfil dos medicamentos prescritos para idosos em uma Unidade Básica de Saúde do município de Ijuí-RS

Buscou-se identificar os medicamentos utilizados pelos idosos atendidos numa Unidade Básica de Saúde do município de Ijuí-RS e entre estes, os medicamentos potencialmente inapropriados para esta faixa etária, além de verificar as potenciais interações envolvendo esses medicamentos. Realizou-se estudo transversal e documental, a partir de 429 prescrições aviadas de janeiro a novembro de 2010, para 286 idosos. A maioria dos idosos era formada por mulheres (67,13%) e a idade média foi de 71,59±7,77 anos; prevaleceu a faixa etária de 60 a 79 anos. Foram dispensadas 87 especialidades farmacêuticas distintas, totalizando 1.336 medicamentos, sendo em média 4,67±2,52 medicamentos prescritos por idoso, variando de um a 15 medicamentos/idoso. Verificou-se polifarmácia em 135 idosos (47,20%). Os medicamentos mais prescritos atuam no sistema cardiovascular, no aparelho digestivo e metabolismo e no sangue e órgão hematopoiéticos. Do total de especialidades farmacêuticas, 14 (16,09%) foram considerados medicamentos potencialmente inapropriados, de acordo com os critérios de Beers, que foram prescritos a 62 (21,68%) idosos. Estão expostos a interações medicamentosas 40 (56,34%) idosos que receberam medicamentos potencialmente inapropriados, dos quais 27 (67,50%) estão expostos a duas ou mais interações. Verificaram-se polimedicação e uso de medicamentos potencialmente inapropriados entre os idosos em estudo, mas estas podem estar sendo necessárias, pois foram identificados medicamentos indicados para as doenças crônicas prevalentes nessa faixa etária. Diante disso, sugere-se o uso dos critérios de Beers na avaliação da farmacoterapia em idosos, destacando-se ainda a necessidade de incorporar o uso de terapias não farmacológicas, a fim de favorecer a redução no consumo de medicamentos.

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.

Polypharmacy among the elderly in the city of São Paulo, Brazil - SABE Study

Polypharmacy for the elderly and associated factors were assessed. A cross-sectional study was conducted using data from the SABE Study (Health, Well-being and Aging), 2006. 1,115 individuals representing 422,377 elderly aged 65 or more, living in São Paulo City, were interviewed. Polypharmacy was defined as the use of five or more medications. A multivariate regression logistics was used. Polypharmacy prevalence was 36%. Female (OR = 1.7; IC 95%: 1.0; 2.9), age over 75 years (OR = 1.9; CI 95%: 1.3; 2.7), higher income (OR = 1.8; CI 95%: 1.2; 2.8), working (OR = 1.8; CI 95%: 1.1; 2.9), regular self assessed health (OR = 1.6; CI 95%: 1.1; 2.3) or poor (OR = 2.6; CI 95%: 1.4; 4.9), hypertension (OR = 2.0; CI 95%: 1.4; 2.9), diabetes (OR = 4.1; CI 95%: 2.2; 7.5), rheumatic diseases (OR = 2.3; CI 95%: 1.5; 3.6) and cardiac problems (OR = 2.9; CI 95%: 1.9; 4.5) were associated positively with polypharmacy. Using only the public health system (OR = 0.5, 95% CI: 0.3; 0.7) was inversely associated with polypharmacy. Medicines for the cardiovascular system and for the alimentary tract and metabolism were the most used. The knowledge of factors associated with polypharmacy, such as those identified in this study, may be useful to alert health professionals about the importance of identifying and monitoring the elderly groups most vulnerable to polypharmacy.

[Factors associated with low adherence to medication in older adults]

OBJECTIVE

To assess factors associated with low adherence to pharmacotherapy in older adults.

METHODS

Cross-sectional population-based study, with a representative sample of 1,593 individuals aged 60 or older, living in the urban area of Bagé, RS, Southern Brazil, in 2008. A multiple stage sampling model was used. The data were collected through individual household interviews. The analyses of the association between low adherence regarding pharmacotherapy, measured using the Brief Medication Questionnaire (BMQ), and demographic, socioeconomic, behavioral, health, assistance and prescription factors were carried out applying Poisson regression model to assess crude and adjusted prevalence ratios, their respective 95% confidence intervals and p-value (Wald test).

RESULTS

Around 78.0% of individuals reported have taken at least one medication in the seven days prior to the interview. Of these, approximately one third (28.7%) were considered to have low adherence to the treatment. The factors significantly associated to low adherence to treatment were: age (65 to 74 years old), not having health insurance, having to purchase (totally or partially) their own medicines, having three or more morbidities, having functional disabilities and using three or more medicines.

CONCLUSIONS

The increased use of medicines by older adults, because of the high prevalence of non-communicable diseases in this group, and the access to the treatment need to be considered by health care professionals regarding fostering adherence to treatment, which increases therapeutic solutions and quality of life among older people.

Prevalence and costs of hospitalizations for poisoning and accidental intoxication in Brazilian elderly

A cross-sectional study of secondary data/information obtained from the Hospital Information System (HIS) spanning the years 2008 - 2009 was performed. The distribution of the main hospital admissions by gender, age, color/race, region and federal unit of residence, average expenditure and average length of hospital stay, year of hospitalization and mortality rates (MR) were studied. The data collected were tabulated by TabNet and keyed into Microsoft Excel 2007. It was verified that elderly males (54.3%), from 60 to 69 years old (50.6%), nonwhites (36.3%) and residents of Southeast and North regions of the country had the highest rates of hospitalization. Seniors were hospitalized for an average of 4.8 days, and the major causes were exposure to alcohol (43.7%) and to drugs (33.9%). Expenses related to hospital admissions were, on average, R$ 529,817.70. The highest mortality rates were recorded among females (MR = 4.34), in elderly, 80 years or older (MR = 10.16) and Caucasians (MR = 3.95), where pharmacological substances with action on the Autonomic Nervous System were the leading cause of death. There are demographic differences in morbi-mortality of these elderly since, although men and younger elderly were the main victims, women and elderly of advanced age have greater mortality. The leading causes of hospitalization were alcohol and drugs.

Potentially inappropriate medication use among institutionalized elderly individuals in southeastern Brazil

In recent decades, the elderly population in Brazil has grown rapidly, as has concern for the health of this population. Institutionalization in nursing homes has appeared as an alternative form of health care for frail elderly that live alone. The present study evaluated the pharmacotherapy and inappropriate drug prescriptions for institutionalized elderly patients living in long-term institutions in southeastern Brazil. This research was conducted at five institutions with a total sample of 151 individuals aged at least 60 years. Databases were used to identify drug interactions, defined daily dose and inappropriate prescriptions. The prevalence of drug intake among the elderly was 95.36%, and there were an average of 3.31 ± 1.80 drug prescriptions per individual. Based on Beers criteria, the prevalence of inappropriate prescriptions was 25.83%. In addition, 70.2% of prescriptions were prescribed at a higher dosage than the defined daily dose (ATC/WHO). Potential drug interactions were identified for 54.11% of prescriptions; 81.42% of these were of moderate severity. The main inappropriate drugs were prescribed for cardiovascular and nervous system problems. Institutionalized elderly individuals presented a high consumption and misuse of medications, requiring professional intervention to monitor prescriptions and improve the quality of service for this population.

[Use of medicines by individuals with hypertension and diabetes in municipalities covered by the Pharmacy Network in Minas Gerais State, Brazil]

This article analyzes the use of medicines by individuals with hypertension and/or diabetes mellitus who received their medication through a public network of pharmacies, with a particular emphasis on gender differences. During the first two months of 2010, individuals with hypertension and/or diabetes were interviewed in half of the 64 municipalities (counties) participating in the Minas Gerais Pharmacy Network. Mean age of the 4,777 interviewees was 60.9 years, which may have contributed to the high mean number of medicines used (4.0 among women and 3.5 among men). The most frequently used drugs were those acting on the cardiovascular system (56.3%), alimentary tract and metabolism (14.9%), and nervous system (13.8%), consistent with the sample's epidemiological profile. Women and more elderly individuals tended to use more medicines. The findings show high expenditures on medicines by the interviewees and suggest the design of educational activities targeting rational use of medication.

[Evaluation of pharmacotherapy prescribed to institutionalized elderly]

Cross-sectional study, quantitative, descriptive and exploratory research, which aimed to evaluate the profile and quality of pharmacotherapy prescribed to elderly residents in long-stay institutions located in Londrina-PR. The population consisted of 203 elderly patients with predominantly female, mean aged 76.4 years. It was found that 97.0% of the population used one drug. One hundred and fifty one different active ingredients were prescribed, with an average of 5.3 per elderly. From all of the individuals surveyed, 59.9% were subjected to polypharmacy. It was identified 359 possible drug interactions, and 58.1% of the elderly were exposed to these events. It was found that was prescribed at least one drug of improper category to 58.1% of the elderly who were using drugs.

[The characterization of elderly medication users living in long-term care facilities]

The objectives of this study were to characterize the elderly living in a long-term care facility in terms of their medication use and verify the existence of polypharmacy. This descriptive quantitative study was performed using a database from the research: The profile of the elderly living in a long-term care institution for the aged: a proposal for nursing/health action. A total of 39 elderly individuals who used medications were selected. It was found that most were women, aged between 80-89 years, who were literate and widowed. Circulatory system diseases were the most frequent. The elderly used a mean of 3.7 medications, and 30.8% took multiple medications. The most commonly used medications were for the cardiovascular system. It was found that some individuals used medications considered inappropriate for the elderly population. We hope to sensitize health professionals to promote a rational and careful use of medications among institutionalized elderly individuals.

Perfil socioeconômico, epidemiológico e farmacoterapêutico de idosos institucionalizados de Brasília, Brasil

O objetivo deste estudo é descrever o perfil socioeconômico, epidemiológico e farmacoterapêutico de 154 idosos de cinco Instituições de Longa Permanência de Brasília por meio de questionário adaptado do Método Dáder e complementado com informações dos prontuários. A amostra é caracterizada por indivíduos solteiros e viúvos, em sua maioria homens, com idade média de 74,6 anos, sedentários, com estado cognitivo preservado, baixa renda mensal e baixo nível de escolaridade. O grupo consome de quatro a cinco medicamentos e é acometido, principalmente, por distúrbios psiquiátricos e cardiovasculares. Os medicamentos mais utilizados são os cardiovasculares e os psicofármacos. A adesão à farmacoterapia é comprometida pela falta de conhecimento sobre a prescrição médica atual, dificuldade de acesso e recusa em tomar os medicamentos prescritos. Resultados sugerem que tal perfil influencia a qualidade e a eficácia da terapêutica medicamentosa indicando a necessidade de implementação de um acompanhamento farmacoterapeutico a esses idosos bem como de políticas públicas de saúde mais focadas nas particularidades dessa população a fim de proporcionar melhoria da qualidade de vida e redução dos custos com assistência à saúde.

Acompanhamento farmacoterapêutico em pacientes dislipidêmicos de um lar de idosos da cidade de Novo Hamburgo-RS

INTRODUÇÃO: A partir do último século, observou-se aumento na expectativa de vida e na incidência de patologia na população idosa, principalmente doenças crônicas. OBJETIVO: Avaliar o efeito do acompanhamento farmacoterapêutico (AF) em pacientes dislipidêmicos de um lar de idosos da cidade de Novo Hamburgo, RS. METODOLOGIA: Trata-se de estudo quantitativo, observacional com delineamento longitudinal retrospectivo, que avaliou 50 pacientes idosos residentes de um lar geriátrico (80,2 ± 7,64 anos, 32 mulheres). Foi avaliado o perfil lipídico desses pacientes (colesterol total, triglicerídeos, HDL e LDL) antes e após AF de um ano. A análise dos resultados ocorreu por meio de estatística descritiva e teste t Student ou U de Mann Whitney para amostras pareadas. RESULTADOS: 56% dos pacientes apresentaram alteração no perfil lipídico no início do estudo e, 30% ao final, ocorrendo significativa melhora após o AF. Além disso, os níveis de colesterol total apresentaram diminuição favorável após um ano de acompanhamento (206 ± 53 vs. 180 ± 43 mg/dL; P = 0,009). A maioria dos pacientes que apresentou diagnóstico de dislipidemia utilizava medicamentos há pelo menos três meses para o tratamento dessa patologia (estatinas e fibratos). A maioria desses pacientes utilizava os medicamentos de forma correta. CONCLUSÃO: Conclui-se que os pacientes tiveram melhora no seu perfil lipídico após um ano de acompanhamento.

Consumo de medicamentos por idosos, Goiânia, Brasil

OBJETIVO: Analisar o padrão de consumo de medicamentos entre idosos e sua associação com aspectos socioeconômicos e autopercepção de saúde. MÉTODOS: Estudo de base populacional e delineamento transversal com 934 idosos de Goiânia, GO, Brasil, entre dezembro de 2009 e abril de 2010. Os dados foram coletados por meio de questionário. As variáveis estudadas foram: número de medicamentos consumidos, sexo, estado civil, escolaridade, tipo de moradia, idade, renda e autopercepção de saúde. Os medicamentos foram classificados segundo o Anatomical Therapeutic and Chemical Classification. Os medicamentos impróprios para idosos foram identificados segundo o Critério de Beers-Fick. Os testes utilizados foram Qui-quadrado (X²) e exato de Fisher e p foi considerado significativo quando < 0,05. RESULTADOS: Os idosos consumiam 2.846 medicamentos (3,63 medicamentos/idoso). Os mais usuais atuavam no aparelho cardiovascular (38,6%). A prevalência de polifarmácia foi de 26,4% e da automedicação de 35,7%. Os medicamentos mais ingeridos por automedicação foram os analgésicos (30,8%); 24,6% dos idosos consumia medicamento considerado impróprio. Mulheres, viúvos, idosos com 80 anos ou mais e com pior autopercepção de saúde praticavam mais a polifarmácia. A maior prática da automedicação esteve associada com menor escolaridade e pior autopercepção de saúde. CONCLUSÕES: O padrão do consumo de medicamentos por idosos foi semelhante ao encontrado em idosos de outras regiões do Brasil. O número de medicamentos usados, a prevalência das práticas da polifarmácia e automedicação e consumo de medicamentos impróprios estiveram dentro da média nacional.

Potentially inappropriate medications among elderly Brazilian outpatients

CONTEXT AND OBJECTIVES In Brazil, few studies have investigated the prevalence of potentially inappropriate medications (PIMs) among elderly outpatients. This study aimed to determine the prevalence of PIMs prescribed for elderly outpatients, identify the PIMs most commonly involved, and investigate whether age, sex and number of medications are related to prescription of such medications. DESIGN AND SETTING Observational descriptive study developed in the Geriatrics Service of the Central Institute of Hospital das Clínicas (HC), Faculdade de Medicina da Universidade de São Paulo (FMUSP), São Paulo, Brazil. METHODS Prescriptions issued to 1,270 elderly patients (≥ 60 years) were gathered from a database. These prescriptions had been written by geriatricians at a tertiary-level university hospital in São Paulo, Brazil, between February and May 2008. The prescriptions were divided according to sex and age group (60-69, 70-79 and ≥ 80). The Beers criteria were used to evaluate PIMs. RESULTS Most of the sample comprised women (77%) and the mean age was 80.1 years. The mean prevalence of PIM prescriptions was 26.9%. Female sex and number of medications prescribed were associated with prescription of PIMs. The chance of having a PIM prescription was lower among patients ≥ 70 years. CONCLUSION The greater prevalence of PIMs was correlated with female sex. The chance of having a PIM prescription was lower among patients ≥ 70 years and became greater with increasing numbers of medications prescribed (≥ 7).

[Self-medication in the elderly population of Campinas, São Paulo State, Brazil: prevalence and associated factors]

The aim of this study was to evaluate the prevalence and causative factors associated with self-medication in the elderly and identify the main drugs consumed without prescription. A cross-sectional population-based study with stratified clustered two-stage sampling was performed in Campinas, São Paulo, Brazil in 2008 and 2009. Of the 1,515 elderly studied, 80.4% reported using at least one drug during the three days preceding the survey. Of these, 91.1% reported the use of prescription drugs only and the remainder (8.9%) reported simultaneous use of prescribed and non prescribed drugs. After adjustment, a negative association between age ≥ 80 years, hypertension, chronic diseases, use of health services, dental consultations and adherence to a medical plan,and self-medication was found, whereas a positive association was found with per capita income. Dipyrone, acetylsalicylic acid, diclofenac, Ginkgo biloba, paracetamol and homeopathic medicines were among the most used non-prescribed drugs. Pharmaceutical assistance should be provided as a priority to the elderly, to avoid the misuse of medicines and ensure access to the correct drugs.

Uso de medicamentos por idosos de instituições de longa permanência, Brasília-DF, Brasil

O objetivo deste estudo é descrever a utilização de medicamentos por 154 idosos de cinco instituições de longa permanência de Brasília-DF, Brasil, por meio de questionário adaptado do Método Dáder. A amostra é caracterizada em sua maioria por homens, com idade de 74,6 anos, com cognição preservada, baixa renda mensal e baixo nível de escolaridade; em uso de quatro a cinco medicamentos. A adesão à farmacoterapia é comprometida pela falta de conhecimento sobre a prescrição médica, dificuldade de acesso e recusa em tomar os medicamentos. Resultados sugerem a necessidade de investimento na capacitação de recursos humanos e em pesquisas na área a fim de proporcionar melhoria da qualidade de vida e redução dos custos com assistência à saúde.

Riscos da interação droga-nutriente em idosos de instituição de longa permanência

O objetivo do estudo foi verificar riscos da interação droga-nutriente nos idosos residentes em Instituição de Longa Permanência. Trata-se de estudo descritivo, de abordagem quantitativa, realizado em 73 idosos. A coleta dos dados ocorreu em 2008, através da análise dos prontuários, história dietética e avaliação do IMC. Os dados evidenciaram que os medicamentos mais utilizados foram do sistema nervoso e cardiovascular, totalizando 66% das prescrições. Entre 375 medicamentos prescritos, 166 fazem algum tipo de interação, 32,0% diminuem o efeito de absorção do fármaco quando há utilização de cafeína e 14,3% diminuem absorção de vitamina B12. A utilização de diversos medicamentos de uso contínuo pode acarretar prejuízo na absorção de nutrientes, aumentando o risco de desnutrição em idosos. Torna-se indispensável a ação da equipe de saúde, através da avaliação criteriosa dos medicamentos administrados, dietoterapia e a interação entre os mesmos, para beneficiar idosos com melhor aproveitamento da terapêutica e melhoria das condições nutricionais.

[Use of medication by the elderly in urban and rural areas in southern Brazil: a population-based study]

The study aimed to measure use of medication and polypharmacy among the elderly in Carlos Barbosa, Rio Grande do Sul State, Brazil, and to compare socio-demographic, economic, and health characteristics in relation to area of residence (urban versus rural) in a random sample of 811 persons 60 year of age or older. Interviews were used to collect data on socio-demographic characteristics, chronic illnesses, and self-reported use of medications. The association between area of residence and medication or polypharmacy was adjusted for confounders using Poisson regression with robust variance. Prevalence rates for use of medication and polypharmacy were higher among older persons living in the urban area. Living in the urban area was positively and independently associated with use of medication (PR = 1.10; 95%CI: 1.02-1.20) and polypharmacy (PR = 1.83; 95%CI: 1.27-2.65) in this group of elderly in southern Brazil.

Utilização de medicamentos por idosos brasileiros, de acordo com a faixa etária: um inquérito postal

O objetivo deste estudo foi avaliar fatores associados ao uso de medicamentos por idosos. Foi realizado um inquérito postal nacional, com 3 mil idosos, selecionados com base no cadastro do Instituto Nacional do Seguro Social. Foram estimadas a prevalência e a média de medicamentos utilizados nos 15 dias anteriores à pesquisa, segundo faixas etárias. A prevalência de uso de medicamentos foi de 83%, sendo de 87,3% no grupo de 70 anos ou mais, e de 78,8% no de 60-69 anos (p < 0,05). Os idosos com 70 anos ou mais usaram em média 4,4 medicamentos, os mais jovens 3,3. Os medicamentos mais utilizados pertenciam ao sistema cardiovascular. Idade de 70 ou mais anos, sexo feminino, pior percepção de saúde, interrupção de atividades habituais, mais de 6 consultas médicas no último ano, filiação a plano de saúde e relato de 4 ou mais doenças estavam associados ao uso de medicamentos (p < 0,05) entre os participantes. Os resultados ampliam o conhecimento a respeito da utilização de medicamentos pelos idosos brasileiros, evidenciando a necessidade de aprimoramento da assistência farmacêutica voltada para esse subgrupo da população.

Potentially inappropriate medication use in a city of Southeast Brazil

Potentially inappropriate medication use by the Diamantina (Minas Gerais State) population was investigated by analyzing medicine consumption, self-medication, polypharmacy and drug interactions of medicines prescribed among those interviewed. Level of knowledge about rational drug use and its relationship to socio-economic variables was also evaluated using a semi-structured questionnaire. This survey was based on stratified sampling of 423 individuals selected randomly. The prevalence of prescription drug consumption was 42.32% (n=179) and cardiovascular drugs were the most prescribed. Drug interactions were found in 45.81% (n=82) of prescriptions and 92.68% (n=76) of these interactions were moderate, with co-administration of cardiovascular drugs occurring in more than half of the cases. The inappropriate use of medication, according to Beers criteria, occurred in 44.73% of prescriptions to the elderly. The prevalence of self-medication was 63.34% (n=268) while 21.99% (n=91) of individuals administered medications to their children without formal prescriptions, where this practice was associated to analgesic/antipyretic consumption. The population showed a high prevalence of inappropriate use of drugs across all strata of society, representing an issue requiring effective actions to promote rational use of medicines.

Atuação da Estratégia Saúde da Família e do Núcleo de Apoio à Saúde da Família no uso racional de medicamentos em Rio Fortuna, em Santa Catarina

A atenção farmacêutica tem sido foco de grande preocupação principalmente no que diz respeito ao uso correto de medicamentos, automedicação, intoxicações, interações medicamentosas e efeitos adversos danosos à população. O presente trabalho teve como objetivo geral avaliar o uso racional de medicamentos junto à população de abrangência das equipes de saúde da família do município de Rio Fortuna, em Santa Catarina. Os objetivos específicos foram: informar a população sobre o problema do uso e abuso de medicamentos; avaliar a aceitação do debate sobre o tema; identificar polifarmácia domiciliar e o risco de abuso ou intoxicação medicamentosa, bem como servir de educação permanente em saúde aos trabalhadores do setor, e recolher medicamentos ociosos. Este é um estudo descritivo, transversal, quantiqualitativo, com dados coletados em inquérito domiciliar realizado por Agentes Comunitários de Saúde, além da realização de metodologia de educação permanente em saúde por meio de palestras e orientações do uso racional de medicamentos aplicados tanto para a equipe de saúde quanto à população. Foram realizadas 1.054 visitas a domicílios, sendo identificadas 185 famílias de risco quanto à presença de polifarmácia domiciliar. A média do consumo de medicamentos na população geral foi de dois a três comprimidos/habitante/dia, enquanto que, nas famílias em que havia polifarmácias, o consumo passou de nove a dez comprimidos por morador, por dia. Foram realizadas também 13 palestras educativas, ao final das quais aplicou-se questionário avaliativo da importância deste trabalho, no qual 98% dos participantes acharam importante a sua realização, 94% manifestaram que se sentiram mais informados a respeito do uso racional de medicamentos e 50% já praticaram a automedicação. Por meio deste trabalho, pode ter-se a percepção real da necessidade que a população tem do tratamento medicamentoso, muitas vezes sem orientação profissional e o limitado conhecimento dos riscos da automedicação e dos perigos das interações medicamentosas. Além disso, percebe-se que a atuação multiprofissional na atenção em saúde é essencial para o constante aprimoramento do cuidado da saúde e o entendimento de que a educação permanente em saúde, tanto dos profissionais quanto da população e da gestão setorial, pode promover grandes mudanças no paradigma assistencial.

Medicamentos prescritos aos idosos em uma capital do Sul do Brasil e a Relação Municipal de Medicamentos

O objetivo deste trabalho foi descrever os medicamentos prescritos aos idosos residentes na zona urbana do Município de Florianópolis, Santa Catarina, Brasil, nos 30 dias anteriores à entrevista e, a partir disto, comparar com a Relação Municipal de Medicamentos (REMUME). Foi realizado um estudo transversal populacional de base domiciliar, no qual os 1.705 idosos entrevistados relataram ter utilizado o total de 5.458 medicamentos prescritos e dentro dos critérios da pesquisa, que corresponderam a 374 princípios ativos diferentes. Os medicamentos mais utilizados foram os indicados para o sistema cardiovascular, sendo a classe farmacológica dos redutores de colesterol e triglicerídeos os mais prevalentes, apesar de não haver nenhum exemplar desta classe de medicamentos selecionado na REMUME. Embora haja algumas faltas, a REMUME coincide com a maior proporção dos medicamentos prescritos no Município de Florianópolis. A principal diferença entre as prescrições é que as oriundas do SUS estão em maior conformidade com a REMUME.

Perfil de uso de medicamentos por idosos assistidos pelo Programa de Atenção ao Idoso (P.A.I.) da UNIJUÍ

O processo de envelhecimento é caracterizado por várias modificações no organismo, que podem causar alterações no efeito de certos medicamentos, tornando-os inapropriados para idosos por falta de eficácia terapêutica ou por apresentarem efeitos adversos superiores aos benefícios. O objetivo do estudo foi identificar os medicamentos utilizados pelos idosos assistidos pelo Programa de Atenção ao Idoso (P.A.I.) e investigar o uso de medicamentos potencialmente inapropriados nessa população. Realizou-se estudo quantitativo e descritivo, com coleta de dados secundários, a partir de prontuários/cadastros dos idosos atendidos pelo P.A.I. (Projeto de Extensão Universitária da UNIJUÍ). Entre os idosos cadastrados, 16 receberam e/ou estão recebendo acompanhamento farmacoterapêutico pela equipe da farmácia, sendo 11 mulheres, com idade média de 75,2 ± 7,5 anos. Cada idoso recebe em média 7,3 ± 3,3 medicamentos. A polifarmácia foi verificada em 15 idosos. Entre os 117 medicamentos em uso, considerando-se repetições, 13 são inapropriados para idosos, destacando-se diazepam e fluoxetina, cada um utilizado por três idosos. Verifica-se que é imprescindível reduzir o uso de medicamentos inapropriados para melhorar a qualidade de vida dos idosos. É necessária a colaboração do prescritor e do profissional farmacêutico, que é responsável por avaliar a prescrição, identificar riscos relacionados à terapêutica e intervir através da comunicação com o prescritor responsável, fornecendo informações e sugestões que facilitem a utilização de serviços de saúde.

Nutritional status and epidemiological profile of elderly people

We intended to identify and evaluate the association between the socio-demographic and epidemiological characteristics of elderly people with their nutritional characteristics. This is a transversal study PMTI (from the Portuguese name of "Programa Municipal da Terceira Idade"), conducted at Viçosa, MG, Brazil. We analyzed 93 records of elderly people registered since 2006 and who underwent nutritional care. After having analyzed the questionnaire, we performed the descriptive and association analyses in the Epi Info (version 6.04) and Minitab softwares. Of the 93 analyzed records, most elderly people were women (80.4%), with an average of 72 years of age, of which 13.0% were long-lived people. The mean body mass index (BMI) was 27.4 kg/m(2), and 50.5% were overweight. We have found 26.8% elderly patients with hypertension, and 31.6% took antihypertensives. Elderly patients who were overweight are 4.54 times more likely to have arterial hypertension (odds ratio (OR)=4.54; 95% confidence interval (CI)=1.2-2.45). Only 7.5% smoked, 30.1% were alcoholics and 60.2% made physical activities. Inadequacies were found regarding the servings of fruits, dairy products, vegetables and sugars consumed. However, the servings of cereals, leguminous, meat and fat consumed were appropriate. This study showed that the nutritional diagnosis and the epidemiological and socio-demographic studies are critical tools to understand this population group, in addition to being important to the planning of health actions.

Intervenção interdisciplinar enquanto estratégia para o Uso Racional de Medicamentos em idosos

A presente pesquisa avaliou a efetividade de intervenções interdisciplinares, envolvendo médicos, farmacêuticos e nutricionistas, destinadas à promoção do Uso Racional dos Medicamentos. Trata-se de um estudo de caráter prospectivo e analítico, com uma população de mulheres idosas, onde a efetividade da intervenção foi avaliada de acordo com indicadores de Uso Racional dos Medicamentos preconizados pela Organização Mundial de Saúde. As análises estatísticas foram realizadas utilizando-se do teste t ou one-way ANOVA para variáveis discretas, e o teste de qui-quadrado para avaliação categórica das variáveis. Após a intervenção, houve uma redução média no consumo de medicamentos em relação às consultas da pré-intervenção (p=0,001). Os medicamentos utilizados na terapêutica cardiovascular foram os mais consumidos, o que se encontra em consonância com as doenças autoreferidas pelas idosas. Foi possível verificar que a intervenção interdisciplinar em idosas pôde contribuir para melhoria dos indicadores de Uso Racional dos Medicamentos, em especial os de prescrição.

Avaliação do nível de fragilidade em idosos participantes de um grupo de convivência

A Síndrome da Fragilidade é uma condição frequente em idosos e pode ser precursora de incapacidade e quedas. Os objetivos deste estudo foram avaliar o nível de fragilidade em idosos de um Grupo de Convivência (GC) e a relação entre fragilidade, incapacidade e quedas. Participaram do estudo 64 idosos, avaliados de acordo com o Fenótipo de Fragilidade, que é composto pelos indicadores: perda de peso não intencional, auto-relato de fadiga, diminuição da força de preensão, baixo nível de atividade física e redução da velocidade da marcha. Foi considerado frágil o idoso que apresentasse três ou mais critérios, pré-frágil quem apresentasse um ou dois e não-frágil nenhum. Foram utilizadas a escala de Atividades Instrumentais de Vida Diária (AIVD), a escala de Atividades Básicas de Vida Diária (ABVD) e questões sobre história de quedas e medo de cair. O teste Mann-Whitney U e o coeficiente de Spearman foram utilizados (a=0,05). Em relação ao nível de fragilidade, foram encontrados 21 idosos não-frágeis, 42 pré-frágeis e um frágil. Os idosos pré-frágeis apresentaram maior necessidade de assistência em ABVD (p=0,046) e AIVD (p=0,011), maior ocorrência de quedas (p=0,004) e medo de cair (p=0,007) que os não-frágeis. Foram encontradas associações significativas e fracas entre estas variáveis e o nível de fragilidade. Os resultados demonstram a importância de intervenções preventivas em idosos pré-frágeis e sugere que fragilidade e incapacidade são entidades distintas em idosos deste GC.

Beers-Fick criteria and drugs available through the Farmácia Dose Certa program

CONTEXT AND OBJECTIVE

Farmácia Dose Certa is a program available in the State of São Paulo that is a national reference for providing drugs free of charge to the population. Elderly people receiving care deserve special attention regarding drugs that are appropriate for their age group. The objective was to assess the drugs in the program considered to be inappropriate for the elderly.

DESIGN AND SETTING

Descriptive study evaluating free drug distribution in the State of São Paulo, Brazil.

METHODS

Following the criteria proposed by Beers and Fick (drugs or drug classes that should be avoided among elderly people, independent of the diagnosis or clinical condition, because of the high risk of side effects and because other, safer drugs are available), the drugs in the Farmácia Dose Certa program that might be inappropriate for elderly people and the levels of evidence for each drug included were assessed.

RESULTS

Among the available drugs, 10 (25.6%) were included within the Beers-Fick criteria. The drugs selected were: amitriptyline, cimetidine, diazepam, digoxin, fluoxetine, methyldopa, nifedipine, promethazine, thioridazine and ferrous sulfate.

CONCLUSION

The list of drugs available within the Farmácia Dose Certa program may be considered appropriate for the general population, but not completely for the elderly population. Adjusting this list to the pharmacological aspects of aging will reduce the risks of drug interactions, falls, mental confusion and excessive sedation that result from drugs that are considered inappropriate for consumption by elderly people.

Gender differences, polypharmacy, and potential pharmacological interactions in the elderly

OBJECTIVE

This study aims to analyze pharmacological interactions among drugs taken by elderly patients and their age and gender differences in a population from Porto Alegre, Brazil.

METHODS

We retrospectively analyzed the database provided by the Institute of Geriatric and Gerontology, Porto Alegre, Brazil. The database was composed of 438 elderly and includes information about the patients' disease, therapy regimens, utilized drugs. All drugs reported by the elderly patients were classified using the Anatomical Therapeutic and Chemical Classification System. The drug-drug interactions and their severity were assessed using the Micromedex® Healthcare Series.

RESULTS

Of the 438 elderly patients in the data base, 376 (85.8%) used pharmacotherapy, 274 were female, and 90.4% of females used drugs. The average number of drugs used by each individual younger than 80 years was 3.2±2.6. Women younger than 80 years old used more drugs than men in the same age group whereas men older than 80 years increased their use of drugs in relation to other age groups. Therefore, 32.6% of men and 49.2% of women described at least one interaction, and 8.1% of men and 10.6% of women described four or more potential drug-drug interactions. Two-thirds of drug-drug interactions were moderate in both genders, and most of them involved angiotensin-converting enzyme inhibitor, non-steroidal anti-inflammatory, loop and thiazide diuretics, and β-blockers.

CONCLUSION

Elderly patients should be closely monitored, based on drug class, gender, age group and nutritional status.
