Self-medication in older European adults: Prevalence and predictive factors

BACKGROUND/OBJECTIVES

Self-medication, despite some benefits, carries many risks, especially when practiced by older adults who are polymedicated. Information addressing the prevalence and associated factors of self-medication in older age in a European context is scarce and sometimes contradictory. This paper aims to estimate the prevalence of self-medication among older adults across Europe and to identify its predictive factors.

DESIGN

Cross-sectional study.

SETTING

Micro-data from the European Health Interview Survey (2006-2009) was used.

PARTICIPANTS

The sample comprised 31,672 community-dwelling individuals aged 65 and over living in private households in 14 European countries.

MEASUREMENTS

The analyses explored the use, over the last two weeks, of any medicines, supplements, or vitamins that were not prescribed by a doctor.

RESULTS

The mean self-medication prevalence was 26.3 %, being the highest in Poland (49.4 %) and the lowest in Spain (7.8 %). Greater odds of self-medication were found for women and for participants who were younger, divorced, or presented a higher educational degree. The presence of long-standing illness and physical pain or not using prescribed medication also significantly increased the possibility of self-medication. A wide variation in the odds of self-medication between countries was also observed (up to 8 times more for Poland, compared to Spain).

CONCLUSION

Self-medication is a prevalent problem among older Europeans, and even though some think it is risk-free, dangers tend to be greater with advancing age. This study will help identify the groups most likely to have this behavior so that we can focus on targeted educative and preventive initiatives.

Self-medication practices in riverside communities in the Brazilian Amazon Rainforest

OBJECTIVES

to analyze the practice of self-medication and the associated factors in the riverside population of the Middle Solimões river region - Amazon rainforest.

METHODS

a cross-sectional population-based study conducted between April and July 2015, through interviews at home.

RESULTS

the prevalence of self-medication among the riverside population was 76.3%. Analgesics and antibacterials were the main therapeutic classes used in self-medication. Self-medication proved to be associated with the male gender, young people, not having sought the health service in the last month, longer commuting from the community to the urban area and the habit of consuming allopathic medicines on their own.

CONCLUSIONS

self-medication among the riverside population of Coari - Amazon may reflect the need to seek self-care by people, with the use of allopathic medicines without prescription, mainly due to the restricted access to health services.

Trends of drug-related poisoning cases attended to at a poison control center

INTRODUCTION

Drug-related poisonings have a high impact on morbidity and mortality, representing the first cause of intoxication in Brazil.

OBJECTIVE

To describe the trends of cases of drug-related poisonings attended to by a poison control center.

METHOD

A quantitative approach (cross-sectional trend study) with data analysis of cases of drug-related poisonings attended to at the Poison Control Center of University Hospital of the State University of Londrina. Data were collected from service notification records for the period 1985 to 2014. For statistical analysis, a simple linear regression model was used.

RESULTS

Of the 36,707 cases attended to by the service, 22.5% (n = 8,608) were drug-related poisonings. There was an increase in the proportion of cases for both sexes (R2 = 0.195, p = 0.014) and males (R2 = 0.403, p < 0.001). There was a trend towards a higher proportion of cases involving the analgesic, anti-inflammatory and immunosuppressive drug classes (R2 = 0.521, p = 0.018), antidepressants (R2 = 0.923, p < 0.001) and antipsychotics (R2 = 0.869; p < 0.001). Antibiotics showed a trend toward a lower proportion of cases (R2 = 0.773, p = 0.001).

CONCLUSIONS

There was a trend for a higher proportion of cases of drug-related poisonings in males. Also, there was an increased trend towards cases involving analgesics/anti-inflammatories/immunosuppressants, antidepressants and antipsychotics.

Self-medication among participants of an Open University of the Third Age and associated factors

Abstract Objective: to identify the prevalence of self-medication, the therapeutic classes used without medical prescription, the symptoms treated with such medication and associated factors among participants of an Open University of the Third Age (OU3A). Method: a cross-sectional, descriptive and analytical study was carried out, the sample of which was composed of 138 OU3A attendees. To estimate the association between the variables, prevalence ratios (PR), confidence intervals (95% CI), the chi-squared test and Fisher's exact test were used. Results: the majority were aged 60-69 years (61.6%), were female (75.4%), had a health plan (63%) and claimed to self-medicate (59.4%, 95% CI, 0-64.8). The most frequently mentioned therapeutic classes were analgesics (31.9%), muscle relaxants (13.8%), anti-inflammatories (13.0%) and first-generation antihistamines (7.2%). The most commonly reported self-medication symptoms were muscle and joint pain (21.0%), headaches (10.1%) and colds and flu (8.7%). There was a significant association (p = 0.049) among those who self-medicated more frequently and anti-inflammatory use (PR = 1.46, 95% CI = 1.10-1.99). The complaint of muscular and articular pain exhibited a significant association with the diagnosis of arthrosis (p = 0.003, RP = 3.75, 95% CI = 2.07-6.76) and hypothyroidism (p = 0.002, RP = 2.77 ; 95% CI = 1.50-5.10). Conclusion: the most frequently mentioned reasons for self-medicating were previous experience using the drug and the certainty that it is safe. Most of the above medications are potentially inappropriate for the elderly. However, the elderly consider them safe and are unaware of the risks to which they expose them. They may also be unaware that pain treated by self-medication may be related to pre-existing diseases, which require the appropriate professional and treatment.

The use of medication and associated factors among adults living in Campinas, São Paulo, Brazil: differences between men and women

The objective of this study was to verify factors associated with the use of medication by adults, with emphasis on the differences between men and women. It was a population-based, cross-sectional study with cluster sampling conducted in two stages in Campinas in the state of São Paulo in 2008. Among the 2,413 individuals aged 20 or older, the prevalence of use of at least one drug in the three days before the research was 45.4% (95% CI: 41.3 - 49.4) in men and 64.6% (95% CI: 59.8 - 69.2) in women. For adult men over 40 years old who were not working, former smokers, with one or more chronic diseases, with two or more health problems and who sought health care or a health professional in the two weeks preceding the research showed higher prevalence of medication use. Among women, a higher prevalence of use was observed in females over 40, obese, former smokers, who reported a short sleep pattern, with one or more chronic diseases and two or more health problems, and who reported seeking a health care service or professional in the past 15 days. The findings showed some differences in the determinants of drug use in relation to gender, revealing the greater importance of health-related behavior among women.

Uma abordagem sobre o uso de medicamentos nos livros didáticos de biologia como estratégia de promoção de saúde

O uso inadequado de medicamentos constitui uma grande ameaça à saúde pública e os medicamentos ocupam a primeira posição dentre os agentes causadores de intoxicação no Brasil, à frente de venenos para roedores e insetos, drogas ilícitas, agrotóxicos, produtos de limpeza e alimentos estragados. Os Parâmetros Curriculares Nacionais do Ensino Médio (PCN+) dão grande ênfase à saúde, uma vez que encontramos o tema Medicamentos mencionado repetidas vezes em seus conteúdos. O objetivo da pesquisa foi estudar as abordagens sobre o uso de medicamentos nos livros didáticos. Foram analisados onze livros didáticos de biologia, sendo seis constituídos de volumes únicos e cinco com três volumes cada, num total de vinte e um volumes. O uso racional de medicamentos deve ser considerado um tópico importante da promoção da saúde que atinge todos os setores da sociedade, devendo ser enfatizado na educação básica. Diante disso, e com base nos presentes resultados, sugerimos que os livros didáticos analisados sejam adequados às novas legislações e que os conteúdos o URM, atendendo assim as recomendações dos PCN+. Para tanto, os livros poderiam tratar de forma concisa os temas: automedicação, adesão ao tratamento medicamentoso, propagandas e reportagens sobre medicamentos entre outros.

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.

[Self-medication among university students: the influence of the field of study]

The scope of this paper was to investigate the influence of a university student's field of study upon self-medication. A cross-sectional study was conducted through the administration of questionnaires on the profile of the respondents, self-medication and other healthcare-related issues. In all, 342 students from different fields of study were interviewed, 81 of which were from the health area. Of the respondents, 37% reported self-medicating in the last fortnight. The most common health problems for self-medication in this period were general pain (90.4%) and analgesics and antipyretics were the most common form of medication. It was observed that being female (p=0.049), as well as the fact of having health insurance (p=0.036), were significantly associated with self-medication and that studying in the health area was not associated with self-medication (0.139). However, it was found that the influence of advertising (p<0.001), old prescriptions (p=0.041), pharmacists or pharmacy employees (p=0.005), as well as friends, neighbors and relatives (p=0.003) were more significant among university students who were not within the health area, though the influence of acquired knowledge (p<0.001) is more significant among students in the health area.

[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.

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.

Automedicação em adultos de baixa renda no município de São Paulo

OBJETIVO: Estimar a proporção de automedicação em adultos de baixa renda e identificar fatores associados. MÉTODOS: Foram utilizados dados de inquérito populacional realizado no município de São Paulo em 2005, cujo plano amostral incluiu dois domínios, favela e não favela, com amostragem por conglomerados em dois estágios, totalizando 3.226 indivíduos elegíveis. Além de características sociodemográficas e econômicas, foram analisados: uso de medicamentos nos 15 dias anteriores à entrevista, tipo de acesso (gratuito, comprado ou outra) aos medicamentos e os tipos de morbidades (crônicas ou agudas) tratadas, em análise de regressão logística múltipla. RESULTADOS: A proporção de automedicação foi de 27% a 32%. Automedicação esteve fortemente associada à morbidade aguda, ao acesso ao medicamento por compra, à idade menor que 47 anos e medicamentos do grupo terapêutico que atuam no sistema nervoso central. O grupo que atua no sistema nervoso central foi o mais utilizado na automedicação. CONCLUSÕES: O acesso gratuito aos medicamentos mostrou-se fator de proteção para a automedicação. A distribuição de medicamentos e o atendimento adequado devem ser considerados para orientação e redução dos riscos que o uso irracional de medicamentos pode gerar à saúde.

Dengue in an elderly patient

Although elderly populations are more exposed to the risk of getting dengue, the clinical peculiarities of this disease in this age range are not well known. This report is about an 80-year-old woman with dengue complications, self-medicated with salicylate. Literature indicates a more severe clinical condition, high hospitalization rate and significant mortality. This is caused by previous infections by other serotypes of this arbovirus, presence of chronic diseases, immunosenescence and high drug consumption, especially salicylates and the like. Analyses are required in a public health perspective in order to help health professionals that care for patients with dengue in this age range.

[Medication leaflets used by elderly with hypertension: adequacy of information for sanitary regulation and possible implications for health]

The medication leaflets represent the main source of written information supplied to the patients, in special to the elderly. This study aimed to analyze the content of the leaflets of drugs often prescribed for elderly people with hypertension, as well as their adequacy to the sanitary regulations and possible health implications. A descriptive study was conducted in two stages: A, in July 2002, and B, in July 2007. In each stage were analyzed 34 medication leaflets of seven antihypertensive drugs of the National Essential Drugs List (2006). Among the 68 leaflets analyzed, most did not contain all the information required by Portaria nº 110/1997 (89.5%) in the stage A and the RDC nº 140/2003 (100%) in B. In 100% of the leaflets, the legislation had not been fulfilled. Some important topics as way of administration, how to use and overdose had been absent in 76% of the leaflets, the lack of this information has an impact in the security of the antihypertensive users. Based on these data, it was possible to evidence inadequate contents of the medication leaflets. So, it is necessary greater surveillance by Anvisa, to ensure the rational use of medicines and the reduction of the risks to the elderly health.

Self-medication among nursing workers from public hospitals

This study describes the prevalence of self-medication and associated factors among nursing workers. This epidemiological sectional study included 1,509 working nurses from two public hospitals in Rio de Janeiro, Brazil. The medications were identified and classified according to the Anatomical Therapeutic Chemical Index. The self-medication prevalence was 24.2% and the most reported anatomical group treated was the nervous system, while the therapeutic group included analgesics. Self-medication was more prevalent among young people, individuals with minor psychiatric disturbances, non-hypertensive individuals, those who did not exercise, those who reported a disease or injury in the last 15 days, with the highest number of self-diagnosed diseases, nurses, professionals with temporary work contracts and those highly involved with their work. Self-medication is a frequent practice among the nursing team members and is associated with factors that should be taken into account when planning strategies aimed at improving workers' health conditions.

A descriptive review of the methodologies used in household surveys on medicine utilization

Background

Studies carried out in the community enable researchers to understand access to medicines, affordability, and barriers to use from the consumer's point of view, and may stimulate the development of adequate medicines policies. The aim of the present article was to describe methodological and analytical aspects of quantitative studies on medicine utilization carried out at the household level.

Methods

Systematic review of original papers with data collected in studies in which the household was a sampling unit, published between 1995 and 2008. The electronic review was carried out in Medline/Pubmed, Scielo and Lilacs. The reference lists of the papers identified were examined, as well as other publications by their authors. Studies on the utilization of specific pharmacological groups, or those including only respondents with a given disease were excluded.

Results

Out of 4852 papers initially identified in the literature search, 61 fulfilled our inclusion criteria. Most studies were carried out in Europe and North America and used a cross-sectional approach. More than 80% used face-to-face interviews for data collection, and the most frequently used recall period for assessing medicine utilization was 14–15 days. In 59% of the studies, interviewers were trained to request the packaging of the medicines reported by the subjects; medical prescriptions were requested less frequently (15% of the studies).

Conclusion

These data will be useful for updating researchers on what methods their peers are currently using. Such information may help overcome challenges in the planning and analyses of future studies. Moreover, this publication may contribute to the improvement of the quality of medicine use data obtained in household surveys.
