Unsafe storage of household medicines: results from a cross-sectional study of four-year-olds from the 2004 Pelotas birth cohort (Brazil).

BACKGROUND: Unintentional child poisoning represents a significant public health problem across the globe, placing a substantial burden on health services emergency departments. Around the world, every year, thousands of children die as a result of physical injuries, most of which involve children under 5 years old. Medicines are the main products involved in poisoning, and children under 5 years old are the most vulnerable age group. The objective of this study was to measure the prevalence of unsafe storage of medicines in households with a 4-year-old child. METHODS: We used data from the follow-up of 4-year-old in the 2004 Pelotas Birth Cohort Study in Brazil (N = 3799). "Unsafe storage" was considered present when medicines were stored unlocked and within reach of children (at a height below the eye level of the average adult). Independent variables included maternal and family socioeconomic and demographic characteristics and the child's health care. All information was collected during household interviews with the mothers using a standardized questionnaire. The overall prevalence rate with a 95% confidence interval (95% CI) and the prevalence associated with various independent variables were determined. RESULTS: The storage of medicines in unlocked areas was reported by 80.9% of the mothers, and, within reach of children for 26.5%. The overall prevalence rate of unsafe storage of medicines was 21.4% (20.1-22.7%). The main storage locations used were the kitchen (57.0%) and bedroom (53.3%). CONCLUSIONS: The results indicate that medicines were unsafely stored in a 21.4% number of homes, which can contribute to the vulnerability of children to poisoning from medicines. To minimize this risk, education about the safe storage of medicines should be reinforced by health professionals.

Self-medication among adolescents aged 18 years: the 1993 Pelotas (Brazil) birth cohort study.

PURPOSE: To estimate the point prevalence of self-medication among adolescents aged 18 years and to evaluate the type of drugs used (either over-the-counter or prescription drugs) and socioeconomic, health-related, and behavioral correlates of self-medication. METHODS: This cross-sectional study used data from the 1993 Pelotas (Brazil) Birth Cohort Study. Data were obtained through the administration of a questionnaire to adolescents aged 18 years. The outcome variables were point prevalence of medicine use and self-medication collected by self-report. The independent variables studied were gender, continuous medicine use, socioeconomic status, schooling, self-rated health, body mass index, and physical activity levels. Medicines were classified into therapeutic groups according to the Anatomical Therapeutic Chemical classification system. RESULTS: A total of 4,106 adolescents were interviewed. The point prevalence of medicine use was 41.1% (95% confidence interval [CI] 39.6-42.6), and the proportion of self-medication among medicine users was 65.1% (95% CI 62.8-67.4). The point prevalence of self-medication was 26.7% (95% CI 25.4-28.1), and it was higher among female adolescents, those more educated, and those who rated their health as poor. Out of the drugs used for self-medication (58% of all drugs used), 1,003 (78.7%) were nonprescription drugs and 271 (21.3%) were prescription drugs. The most frequently used drugs for self-medication were analgesics (56.1%), systemic antihistamines (7.4%), and anti-inflammatory and antirheumatic products (7.1%). CONCLUSIONS: A high point prevalence of self-medication was found among adolescents, which is particularly concerning due to high use of prescription drugs for self-medication. Interventions are needed to promote rational use of medicines in this population.

Rational use of medicines: prescribing indicators at different levels of health care

This multicenter study aimed to investigate prescribing patterns of drugs at different levels of health care delivery in university-affiliated outpatient clinics located in eight cities in the South and Midwest of Brazil. All prescriptions collected were analyzed for various items, including WHO prescribing indicators. A total of 2,411 prescriptions were analyzed, and 469 drugs were identified. The number of drugs prescribed per encounter, the frequency of polypharmacy, and the percentage of encounters with at least one injection or antibiotic prescribed were higher in centers providing primary health care services, compared to those where this type of care is not provided. Most drugs (86.1%) were prescribed by generic name. In centers with primary health care services, drug availability was higher, drugs included in the National and Municipal Lists of Essential Medicines were more frequently prescribed, and patients were given more instructions. However, warnings and non-pharmacological measures were less frequently recommended. This study reveals trends in drug prescribing at different levels of health care delivery in university-affiliated outpatient clinics and indicates possible areas for improvement in prescribing practices.

Este estudo multicêntrico teve como objetivo investigar o padrão de prescrição de medicamentos para pacientes ambulatoriais atendidos em serviços de saúde vinculados a universidades com diferentes níveis de atenção, em oito cidades do sul e centro-oeste do Brasil. As prescrições coletadas foram submetidas à análise de diversos itens, incluindo os indicadores de prescrição propostos pela OMS. No total, 2.411 prescrições foram analisadas e 469 medicamentos foram identificados. O número de medicamentos prescritos por consulta, a frequência de polifarmácia e a porcentagem de consultas com pelo menos um medicamento injetável ou um antimicrobiano prescrito foram maiores em centros de saúde que ofereciam cuidados de atenção básica, em comparação com aqueles que não dispunham desse tipo de atendimento. A maioria dos medicamentos foi prescrita pelo nome genérico (86,1%). Em unidades com cuidados de atenção básica, a acessibilidade foi maior, a prescrição de medicamentos presentes nas Listas Nacional e Municipais de Medicamentos Essenciais foi mais frequente e instruções foram fornecidas aos pacientes mais comumente. Entretanto, advertências e medidas não farmacológicas foram indicadas com menor frequência. Este estudo revela tendências de prescrição de medicamentos em serviços de saúde ligados a universidades, com diferentes níveis de atenção, e indica possíveis áreas de melhoria na prática da prescrição.

[Affordability and availability of drugs for treatment of chronic diseases in the public health care system]. / Capacidade aquisitiva e disponibilidade de medicamentos para doenças crônicas no setor público.

OBJECTIVE: To assess the affordability by workers of drugs used for treatment of chronic diseases, as well as the availability of the reference, similar, or generic forms of these drugs in the public health care system. METHODS: We employed the methodology recommended by the World Health Organization (WHO) and Health Action International (HAI) for the standardized collection of information on selling prices in the private sector and availability in the public health care system of drugs in six cities in the state of Rio Grande do Sul, Brazil. Data were collected from November 2008 to January 2009. Affordability was estimated as the number of salary days required for a worker receiving the national minimum wage to buy, in a private pharmacy, the amount of medication required for one month of treatment. Availability was assessed by the presence of these drugs in public health care system facilities. RESULTS: Twenty-two public facilities and 30 private pharmacies were studied. Of 21 drugs used for the treatment of seven chronic disorders, only nine were available free of charge in the six cities. Mean availability ranged from 83.3% (São Leopoldo) to 97.6% (Caxias do Sul). Affordability ranged from 0.4 to 10.5 salary days for reference drugs, 0.2 to 8.4 salary days for similar drugs, and 0.3 to 3.8 salary days for generic drugs. CONCLUSIONS: The overall availability of the drugs surveyed was higher than the 80% recommended by WHO. However, some treatments were not available, or had limited availability in the public system. Concerning affordability, the number of salary days required to buy these drugs may affect the continuation of drug treatments for chronic diseases.

Capacidade aquisitiva e disponibilidade de medicamentos para doenças crônicas no setor público / Affordability and availability of drugs for treatment of chronic diseases in the public health care system

OBJETIVO: Avaliar a capacidade aquisitiva do trabalhador para pagar medicamentos utilizados no tratamento de doenças crônicas e a disponibilidade desses medicamentos na forma de referência, similar ou genérica para fornecimento gratuito no setor público. MÉTODOS: Utilizou-se metodologia preconizada pela Organização Mundial da Saúde (OMS) e Health Action International (HAI) para coleta padronizada de informações sobre preços de venda no setor privado e disponibilidade no setor público de medicamentos em seis cidades do Rio Grande do Sul, Brasil. A coleta de dados ocorreu de novembro de 2008 a janeiro de 2009. A capacidade aquisitiva foi estimada como o número de dias do salário que um trabalhador com rendimento de 1 salário mínimo nacional necessita trabalhar para adquirir, em uma farmácia privada, a quantidade necessária de medicamento para 1 mês de tratamento. A disponibilidade foi avaliada verificando-se a presença dos medicamentos nas farmácias do setor público. RESULTADOS: A pesquisa incluiu 22 estabelecimentos públicos e 30 farmácias privadas. Dos 21 medicamentos utilizados no tratamento de sete doenças crônicas, apenas nove eram disponibilizados gratuitamente nos seis municípios pesquisados. O percentual médio da disponibilidade variou de 83,3 por cento (São Leopoldo) a 97,6 por cento (Caxias do Sul). A capacidade aquisitiva variou de 0,4 a 10,5 dias de salário para medicamentos de referência; de 0,2 a 8,4 dias de salário para medicamentos similares; e de 0,3 a 3,8 dias de salário para medicamentos genéricos. CONCLUSÕES: A disponibilidade geral dos medicamentos pesquisados foi superior aos 80 por cento recomendados pela OMS; porém, alguns tratamentos não estavam disponíveis, ou apresentaram uma disponibilidade limitada no setor público. A capacidade aquisitiva dos trabalhadores nos municípios estudados indicou um comprometimento de dias do salário que pode afetar a continuidade dos tratamentos com medicamentos para doenças crônicas.

Use of medicines with unknown fetal risk among parturient women from the 2004 Pelotas Birth Cohort (Brazil).

BACKGROUND: To estimate the exposure to medicines with unknown fetal risk during pregnancy and to analyze the maternal characteristics associated with it. METHODS: A questionnaire was administered to 4,189 mothers of children belonging to the 2004 Pelotas (Brazil) birth cohort study about use of any medicine during gestation. We evaluated the associations between use of medicines with unknown fetal risk and the independent variables through logistic regression models. Unknown fetal risk was defined as medicines in which studies in animals have revealed adverse effects on the fetus, and no controlled studies in women, or studies in women and animals, are available. RESULTS: Out of the 4,189 women, 52.5% used at least one medicine from unknown fetal risk. Use of these medicines was associated with white skin color, high schooling, high income, six or more antenatal care consultations, hospital admission during pregnancy, and morbidity during gestation. CONCLUSION: The use of unknown fetal risk medicines is high, suggesting that their use must be addressed with caution with the aim of restricting their use to cases in which the benefits are greater than the potential risks.

Household expenditures for medicines and the role of free medicines in the Brazilian public health system.

OBJECTIVES: We sought to investigate, across different socioeconomic groups, the proportion of household medicine expenses that were paid by households and the proportion paid by the Brazilian national health system. METHODS: We carried out a survey in Porto Alegre, Brazil, that included 2988 individuals of all ages. We defined 2 expenditure variables: "out-of-pocket medicines value" (the sum of retail prices of all medicines used by family members within the previous 15 days and paid for out of pocket) and "free medicines value" (a similar definition for medicines obtained without charge). RESULTS: In 2003, the Brazilian national health system provided, free of charge, 78% of the monetary value of medicines reported (79% in the bottom wealth quintile and 32% in the top 2 quintiles). The mean out-of-pocket expense for medicines was 6 times greater among the top wealth quintiles compared with those in lower quintiles, but free medicines constituted a 3-times-greater proportion of potential expenditures for medicines among the bottom quintile than among the top 2 quintiles. CONCLUSIONS: Free provision of medicines seems to be saving substantial amounts of medicine expenditures for poor people in Brazil.
