The effect of different levothyroxine administration regimens on thyroid hormone levels: a systematic review, pairwise, and network meta-analysis.

INTRODUCTION: This systematic review aimed to compare the effect of alternative levothyroxine administration regimens on thyroid hormone levels and patient-reported outcomes (PROs) among adults with hypothyroidism. METHODS: We searched PubMed, Embase, CENTRAL, CINAHL, LILACS, SciELO, Scopus, Web of Science, OpenGrey, ProQuest, ClinicalTrials.gov, and ICTRP from inception to May/2023 for randomized controlled trials (RCTs). We assessed the risk of bias with Cochrane Risk of Bias 2.0 tool. We analyzed TSH levels by pairwise and network meta-analyses (NMA). The FT4 levels and PROs were qualitatively assessed. RESULTS: We included 14 RCTs (906 participants) comparing different regimens, as bedtime vs. before breakfast. A total of 12 RCTs were at high risk of bias. Seven RCTs were included in the TSH meta-analysis, where the mean difference (MD) and 95% confidence interval (CI) were as follows: bedtime vs before breakfast (4 RCTs) 0.69 (-1.67-3.04), I2 = 92%, very low certainty evidence; weekly dose vs before breakfast (2 RCTs) 1.68 (0.94-2.41), I2 = 0%, low certainty evidence; and at breakfast vs before breakfast (1 RCT) 0.65 (-1.11-2.41), very low certainty evidence. The NMA showed no evidence of differences in TSH level with different regimens. CONCLUSION: The evidence is insufficient to determine the most effective levothyroxine administration regimen for hypothyroidism. SYSTEMATIC REVIEW REGISTRATION: PROSPERO - CRD42021279375.

Hypertensive Disorders of Pregnancy and Medication Use in the 2015 Pelotas (Brazil) Birth Cohort Study.

Hypertensive disorders of pregnancy account for approximately 22% of all maternal deaths in Latin America and the Caribbean. Pharmacotherapies play an important role in preventing and reducing the occurrence of adverse outcomes. However, the patterns of medications used for treating women with hypertensive disorders of pregnancy (HDP) living in this country is unclear. A population-based birth cohort study including 4262 women was conducted to describe the pattern of use of cardiovascular agents and acetylsalicylic acid between women with and without HDP in the 2015 Pelotas (Brazil) Birth Cohort. The prevalence of maternal and perinatal outcomes in this population was also assessed. HDP were classified according to Ministry of Health recommendations. Medications were defined using the Anatomical Therapeutic Chemical Classification System and the substance name. In this cohort, 1336 (31.3%) of women had HDP. Gestational hypertension was present in 636 (47.6%) women, 409 (30.6%) had chronic hypertension, 191 (14.3%) pre-eclampsia, and 89 (6.7%) pre-eclampsia superimposed on chronic hypertension. Approximately 70% of women with HDP reported not using any cardiovascular medications. Methyldopa in monotherapy was the most frequent treatment (16%), regardless of the type of HDP. Omega-3 was the medication most frequently reported by women without HDP. Preterm delivery, caesarean section, low birth weight, and neonatal intensive care admissions were more prevalent in women with HDP. Patterns of use of methyldopa were in-line with the Brazilian guidelines as the first-line therapy for HDP. However, the large number of women with HDP not using medications to manage HDP requires further investigation.

Medication Use among Pregnant Women from the 2015 Pelotas (Brazil) Birth Cohort Study.

Background: Medication use during pregnancy is a common practice that has been increasing in recent years. The aim of this study is to describe medication use among pregnant women from the 2015 Pelotas (Brazil) Birth Cohort Study. Methods: This paper relies on a population-based cohort study including 4270 women. Participants completed a questionnaire about the antenatal period, including information about medication use. We performed descriptive analyses of the sample and the medications used and adjusted analyses for the use of medications and self-medication. Results: The prevalence of medication use was 92.5% (95% CI 91.7-93.3), excluding iron salts, folic acid, vitamins, and other minerals. The prevalence of self-medication was 27.7% (95% CI 26.3-29.1). In the adjusted analysis, women who had three or more health problems during pregnancy demonstrated higher use of medicines. Self-medication was higher in lower income groups and among smokers and multiparous women (three pregnancies or more). Acetaminophen, scopolamine, and dimenhydrinate were the medications most commonly used. Conclusions: This study describes the pattern of drug use among pregnant women in a population-based cohort study, with a high prevalence of self-medication. Greater awareness of the risks of self-medication during pregnancy is required, focusing on groups more prone to this practice, as well as ensuring qualified multidisciplinary prenatal care.

Use of Medications by Breastfeeding Women in the 2015 Pelotas (Brazil) Birth Cohort Study.

Background: This study describes medication use by women up to 3 months postpartum and evaluates the association between medication use by women who were still breastfeeding at 3 months postpartum and weaning at 6 and 12 months. Methods: Population-based cohort, including women who breastfed (n = 3988). Medications were classified according to Hale's lactation risk categories and Brazilian Ministry of Health criteria. Duration of breastfeeding was analysed using Cox regression models and Kaplan-Meier curves, including only women who were still breastfeeding at three months postpartum. Results: Medication use with some risk for lactation was frequent (79.6% regarding Hale's risk categories and 12.3% regarding Brazilian Ministry of Health criteria). We did not find statistically significant differences for weaning at 6 or 12 months between the group who did not use medication or used only compatible medications and the group who used medications with some risk for lactation, according to both criteria. Conclusions: Our study found no association between weaning rates across the different breastfeeding safety categories of medications in women who were still breastfeeding at three months postpartum. Therefore, women who took medications and stopped breastfeeding in the first three months postpartum because of adverse side-effects associated with medications could not be addressed in this analysis.

Users' preferences and perceptions of the comprehensibility and readability of medication labels.

OBJECTIVE: To evaluate the labeling preferences of medication users and characterize their perceptions of the comprehensibility and readability of medication labels. METHODS: We conducted a population-based cross-sectional study of medication users aged 18 years or older in 10 Brazilian capital cities. Perceptions of the comprehensibility and readability of medication labels in relation to sociodemographic characteristics were evaluated by Poisson regression models with robust variance. Labeling preferences were assessed through questions addressing possible improvements and through the use of digitally simulated packages. RESULTS: Of 6,255 medication users interviewed, more than half found it difficult or very difficult to read (50.8%) and/or understand (52.0%) medication labels. Difficulties were more pronounced for participants aged 40 years or older, with lower levels of education, and non-whites. Increasing the font size (93.7%), describing the indications for use (95.9%) and contraindications (95.6%) on the label, and highlighting the expiration date (96.3%) were the most widely accepted improvements. In the evaluation of simulated packages, users preferred factors that improved readability, such as increased font size, use of graphic elements and color to highlight the concentration of the active ingredient, and contrast between the font color and background. The new simulated package design, with increased font size, color to highlight the concentration and contrast between the font color and background, was preferred over the standard design by 77.0% of participants. CONCLUSION: Based on users' perceptions, increased font size and use of graphic elements and color to emphasize critical information, such as expiration date and concentration, are factors that contribute to making medication labels clearer to users. Pharmaceutical industries and policy makers should consider these items when developing labels and defining policies on this issue.

Use of generic medicines by the Brazilian population: an evaluation of PNAUM 2014.

OBJECTIVE: To analyze the existence of differences in the use of generic medicines in Brazil according to demographic and socioeconomic variables and acquisition sources of the medicines. METHODS: Population-based cross-sectional study, conducted with data from the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines). Data collection took place between September, 2013 and February, 2014 in homes of Brazilian cities (urban area). The use of medicines has been investigated in relation to the treatment of chronic diseases and, in the case of acute events, regarding use over the previous 15 days. Generics were identified by visualization of packaging presented by the users of the medicines. The independent variables used were sex, age, education level, economic class, and region of the Country. The statistical significance of differences between the groups was evaluated by Pearson's Chi-squared test, considering a 5% significance level. RESULTS: The prevalence of generic medicines use was 45.5% (95%CI 43.7-47.3). There was no difference considering education level. The prevalence was higher in females (47.0%; 95%CI 44.9-49.0) than in males (43.1%; 95%CI 40.5-45.8), and were higher with increasing age. Generic medicines were more used in the economic class C (47.0%; 95%CI 44.9-49.1) and in the South (50.6%; 95%CI 46.6-54.6) and Southeast (49.9%; 95%CI 46.8-53.0) regions. Generics accounted for 37.3% of the medicines provided by the Brazilian Unified Health System. CONCLUSIONS: Currently, there is a choice of purchase or free provision by the Brazilian Unified Health System, characterized by quality assurance and reduced price regarding branded medicines considered as reference. In the private market, a considerable part of the population is choosing generic medicines thanks to the availability of this option for virtually all medicines most used by the population. OBJETIVO: Analisar se há diferença no uso de medicamentos genéricos no Brasil segundo variáveis demográficas, socioeconômicas e fontes de obtenção dos medicamentos. MÉTODOS: Estudo transversal de base populacional, conduzido com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), com coleta de dados entre setembro de 2013 e fevereiro de 2014 em residências de municípios brasileiros urbanos. O uso dos medicamentos foi investigado em relação ao tratamento de doenças crônicas e, no caso de eventos agudos, quanto ao uso nos últimos 15 dias. Os genéricos foram identificados por visualização das embalagens apresentadas pelos usuários dos medicamentos. As variáveis independentes utilizadas foram sexo, idade, escolaridade, classe econômica e região do País. A avaliação da significância estatística das diferenças entre os grupos foi analisada pelo teste Qui-quadrado de Pearson, considerando nível de significância de 5%. RESULTADOS: A prevalência de uso de genéricos foi de 45,5% (IC95% 43,7-47,3). Não houve diferença por escolaridade, as prevalências foram maiores no sexo feminino (47,0%; IC95% 44,9-49,0) em relação ao masculino (43,1%; IC95% 40,5-45,8) e foram crescentes com o aumento da idade. Maiores usos de genéricos foram encontrados na classe econômica C (47,0%; IC95% 44,9-49,1) e nas regiões Sul (50,6%; IC95% 46,6-54,6) e Sudeste (49,9%; IC95% 46,8-53,0). Observou-se ainda que os genéricos representaram 37,3% dos medicamentos disponibilizados pelo Sistema Único de Saúde . CONCLUSÕES: Pode-se concluir que hoje existe uma alternativa de compra ou fornecimento gratuito pelo Sistema Único de Saúde, caracterizada por garantia de qualidade e preço reduzido em relação aos medicamentos de marca comercial considerados como referência. No mercado privado, boa parte da população está optando pelo uso de medicamentos genéricos, graças à disponibilidade dessa opção para praticamente todos os medicamentos mais utilizados pela população.

Distribution of genes related to antimicrobial resistance in different oral environments: a systematic review.

INTRODUCTION: The oral cavity is the main source of microorganisms for odontogenic infections. It is important to perform an extensive analysis regarding the reports on the presence of bacteria that carry resistance genes to antimicrobial agents. The aim of the study was to verify the reports on the distribution of genes associated with resistance to antibiotics prescribed in dentistry in different human oral sites. METHODS: A systematic review was conducted in electronic databases and gray literature to analyze clinical studies that detected genes of bacterial resistance to antibiotics in saliva, supragingival biofilm, and endodontic infections. Data regarding the research group, geographic location, sample source, number of subjects, methods for sample analysis, the targeted gene groups, and the detection rates were collected. Descriptive data analysis was performed. RESULTS: Preliminary analysis was performed in 152 titles; 50 abstracts were reviewed, and 29 full texts were obtained. Nine articles matched the inclusion criteria (saliva = 2, supragingival biofilm = 1, and endodontic infections = 6). The presence of 33 different targeted genes was evaluated. The most frequently investigated groups of genes were tetracycline and lactamics (tetM, tetQ, tetW, and cfxA). There was a wide range for the detection rates of each resistance gene among studies and for each specific gene group. CONCLUSIONS: This systematic review highlights the presence of resistance genes to antimicrobial agents in saliva, dental biofilm, and endodontic infections, especially for tetracycline and lactamics. There is a lack of reports on the presence of genes and resulting outcomes obtained through the therapeutic approaches for infection control.

Information on adverse events in randomised clinical trials assessing drug interventions published in four medical journals with high impact factors.

BACKGROUND: The impact of the extension of the Consolidated Standards of Reporting Trials (CONSORT) statement, which was published in 2004 and aimed to improve the quality of the safety information presented in clinical trials, remains uncertain. OBJECTIVE: To assess the incorporation of the CONSORT statement extension's recommendations in randomised clinical trials (RCTs) evaluating drug therapies published in high-impact medical journals. METHODS: Using Medline, 122 RCTs published in 2009 were selected from BMJ, JAMA, Lancet, and NEJM. A structured form was used to identify the harms information reported in the RCTs, following the recommendations of the CONSORT statement extension. RESULTS: The most frequently met CONSORT recommendation was the mention of harms in the title or abstract of the paper (72.1% of the papers analysed); the least-met recommendation was the reporting of how the harms information was collected (10.7%). The studies that focused on harms presented better information on safety, but only 10.8% met all recommendations in the CONSORT statement. CONCLUSION: The adverse event information was insufficient for the RCTs published in four high-impact medical journals five years after the publication of the extension of the CONSORT statement.

Utilização de medicamentos entre crianças de zero a seis anos: um estudo de base populacional no sul do Brasil / Drug use among children between zero and six years old: a population baseline study in the south of Brazil

O objetivo do artigo é estimar a prevalência de utilização de medicamentos em crianças de zero a seis anos, analisando as características sociodemográficas associadas, e avaliar a adequação dos medicamentos quanto às indicações em pediatria e às restrições por faixa etária. Estudo transversal de amostra constituída por crianças de seis anos ou menos residentes em uma cidade no sul do Brasil, através de amostragem por conglomerados. Aplicou-se questionário padronizado sobre o uso de medicamentos nos 15 dias anteriores à entrevista. Foi realizada análise descritiva e avaliada a associação entre o uso de medicamentos e fatores sociodemográficos, além da análise da adequação dos medicamentos mais prevalentes. Das 687 crianças avaliadas, 52% utilizaram pelo menos um medicamento no período estudado. Não foram encontradas associações entre o uso de medicamentos e características sociodemográficas, à exceção da renda per capita mensal. O medicamento mais utilizado foi o paracetamol (17,1%), seguido da amoxicilina (9,5%) e da dipirona (8,4%). Entre os dez medicamentos mais utilizados, seis apresentaram restrições de faixa etária em pediatria. Os resultados indicam uso expressivo de medicamentos, incluindo os com restrições de faixa etária, particularmente em crianças menores de dois anos.

The scope of this article was to estimate the prevalence of medication use in children between zero and six years old, analyzing the associated socio-demographic characteristics, and evaluating the adequacy of the medication with respect to pediatric recommendations and restrictions per age group. A cross-sectional study was conducted by means of cluster sampling on a sample comprised of children aged six or under, residents of a city in the south of Brazil. A standardized questionnaire about medication use 15 days prior to the interview was applied. A descriptive analysis was carried out, and the association between medication use and socio-demographic factors was evaluated, as well as the analysis of the pediatric adequacy of the most prevalent medication. Of the 687 children evaluated, 52% used at least one drug in the period. Associations between medication use and socio-demographic characteristics were not found, with the exception of per capita monthly income. The most prevalent medication was paracetamol (17.1%), followed by amoxicillin (9.5%) and dipyrone (8.4%). Among the ten drugs most used in children, six had pediatric restrictions for the age group. The results indicate significant use of medication, including medication with age restrictions, particularly for children under two years of age.

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.

Uso alternado de antipiréticos para tratamento da febre em crianças: revisão sistemática de ensaios clínicos randomizados / Alternating antipyretics in the treatment of fever in children: a systematic review of randomized clinical trials

OBJETIVO: Sumarizar as evidências existentes sobre a eficácia da terapia alternada com antipiréticos no manejo da febre em crianças comparada com monoterapia. FONTES DE DADOS: MEDLINE, EMBASE, Cochrane Library, LILACS, SciELO, IBECS, Web of Science, Clinical Trials, Google Scholar e referências dos artigos encontrados. Foram incluídos na revisão ensaios clínicos randomizados, publicados até dezembro de 2011, em que um dos braços fosse terapia alternada com antipiréticos para tratamento de febre em crianças menores de 12 anos, atendidas em nível ambulatorial. A seleção e extração dos dados foram realizadas independentemente por dois revisores. A qualidade dos estudos foi avaliada de acordo com os itens do CONSORT. SÍNTESE DOS DADOS: Os estudos selecionados apresentaram grande heterogeneidade em relação aos participantes, temperatura para diagnóstico de febre, intervenções (doses e intervalos entre doses) e desfechos avaliados. Os grupos de tratamento variaram de 38 a 464 crianças. Os estudos compararam paracetamol e ibuprofeno alternados com paracetamol e/ou ibuprofeno. Em apenas um estudo foram utilizadas doses diferentes de 15 mg/kg para paracetamol e 10 mg/kg para ibuprofeno, mas os intervalos entre doses variaram consideravelmente. Em nenhum estudo foi avaliado o uso alternado com dipirona ou ácido acetilsalicílico. De modo geral, os artigos apontaram para uma tendência a menor média de temperatura nos grupos de terapia alternada. Poucos efeitos adversos foram relatados. CONCLUSÃO: Embora haja uma tendência na redução das médias de temperatura com antipiréticos alternados em relação aos antipiréticos isolados, não existe evidência suficiente para afirmar que essa prática é mais eficaz que a monoterapia.

OBJECTIVE: To summarize the existing evidence on the efficacy of therapy with alternating antipyretics compared to monotherapy in the management of fever in children. SOURCES: MEDLINE, EMBASE, Cochrane Library, LILACS, SciELO, IBECS, Web of Science, Clinical Trials, Google Scholar and references of the articles found. The review included randomized clinical trials published until December 2011, in which one of the arms was the alternating antipyretics therapy to treat fever in children younger than 12 years, treated on an outpatient basis. Data selection and extraction were performed independently by two reviewers. The quality of the studies was assessed according to CONSORT items. SUMMARY OF THE FINDINGS: The selected studies showed great heterogeneity of participants, temperature for fever diagnosis, interventions (dose and dosing intervals) and assessed outcomes. The treatment groups ranged from 38 to 464 children. The studies compared paracetamol and ibuprofen alternated with paracetamol and/or ibuprofen. Only one study used different doses from the 15 mg/kg for paracetamol and 10 mg/kg for ibuprofen, but the dosing intervals varied considerably. The alternate use with dipyrone or acetylsalicylic acid was not assessed by any of the studies. Overall, the articles pointed to a tendency of lower mean temperatures in groups with alternating therapy. Few adverse effects were reported. CONCLUSION: Although there was a tendency towards the reduction of mean temperatures with alternating antipyretics compared to the use of one antipyretic alone, there is not enough evidence to say that alternating antipyretic therapy is more effective than monotherapy.

[Quality of prenatal care: traditional primary care and Family Health Strategy units in a city in southern Brazil]. / Qualidade do processo da assistência pré-natal: unidades básicas de saúde e unidades de Estratégia Saúde da Família em município no Sul do Brasil.

Prenatal care in traditional primary care units (UBS) and Family Health Strategy units (ESF) was evaluated by a cross-sectional study from July 2009 to February 2010 in Santa Maria, Rio Grande do Sul State, Brazil. Seven hundred and ninety-five postpartum women who had received prenatal care in either of the two types of units were interviewed. Four quality levels were used: level 1 (Kessner index modified by Takeda); level 2, which adds clinical obstetric procedures to level 1; level 3, which adds laboratory tests to level 1; and level 4, which includes all the above parameters. Prenatal care in the Family Health Strategy was superior to that of traditional primary care at all levels, with statistically significant differences in levels 1 and 2. Pregnant women received more guidance and prenatal care was superior in the Family Health Strategy. The study favored the Family Health Strategy, but improvement is still needed in the performance of procedures and laboratory tests in order to enhance prenatal care and strengthen primary care.

Qualidade do processo da assistência pré-natal: unidades básicas de saúde e unidades de Estratégia Saúde da Família em município no Sul do Brasil / Quality of prenatal care: traditional primary care and Family Health Strategy units in a city in southern Brazil

O processo da atenção pré-natal em unidades básicas de saúde tradicionais (UBS) e unidades de Estratégia Saúde da Família (ESF) foi avaliado em Santa Maria, Rio Grande do Sul, Brasil. Foram entrevistadas 795 puérperas que realizaram pré-natal nas UBS ou ESF. Utilizou-se quatro níveis de qualidade: nível 1 (índice de Kessner modificado por Takeda); nível 2, que adiciona ao nível 1 procedimentos clinico-obstétricos; nível 3, que acrescenta ao nível 1 exames laboratoriais; e nível 4, que considera todos os parâmetros anteriores. A atenção pré-natal realizada na ESF foi superior a das UBS em todos os níveis, com diferenças estatisticamente significativas nos níveis 1 e 2. As gestantes da ESF receberam mais orientações. A atenção pré-natal foi favorável à ESF, devendo ser melhorada em relação aos procedimentos e exames, a fim de aprimorar a assistência pré-natal e fortalecer a atenção primária à saúde.

[Use of medication by the elderly in urban and rural areas in southern Brazil: a population-based study]. / Uso de medicamentos entre idosos residentes em áreas urbanas e rurais de município no Sul do Brasil: um estudo de base populacional.

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.

Uso de medicamentos entre idosos residentes em áreas urbanas e rurais de município no Sul do Brasil: um estudo de base populacional / Use of medication by the elderly in urban and rural areas in southern Brazil: a population-based study

O objetivo foi verificar a prevalência de uso de medicamentos e de polifarmácia entre idosos de Carlos Barbosa, Rio Grande do Sul, Brasil, e comparar as características sociodemográficas e de saúde associadas ao uso, segundo o local de moradia. Foi avaliada uma amostra aleatória de 811 idosos com 60 anos ou mais, moradores na área urbana ou rural. Dados sociodemográficos, doenças crônicas, qualidade de vida e medicamentos autorreferidos foram coletados em entrevistas presenciais. Associação entre local de moradia e uso de medicamentos ou polifarmácia, ajustada para potenciais confundidores, foi avaliada por regressão de Poisson com ajuste robusto da variância. A prevalência de uso de medicamentos e de polifarmácia foi maior entre os idosos urbanos. Morar na área urbana apresentou associação positiva e independente com uso de medicamentos (RP = 1,10; IC95 por cento: 1,02-1,20) e polifarmácia (RP = 1,83; IC95 por cento: 1,27-2,65). Morar na área urbana está associado à maior prevalência de uso de medicamentos e de polifarmácia entre idosos.

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 percentCI: 1.02-1.20) and polypharmacy (PR = 1.83; 95 percentCI: 1.27-2.65) in this group of elderly in southern Brazil.

Elaboração e avaliação de material educativo impresso para auxiliar na adesão medicamentosa de pacientes pediátricos pós-alta hospitalar / Development and evaluation of printed educational material to improve the medication compliance of pediatric patients after hospital discharge

O uso frequente de medicamentos off-label ou não licenciados na área da pediatria é um problema mundial que ocorre devido à indisponibilidade de formas farmacêuticas adequadas com dosagens apropriadas para a administração em crianças. Durante a internação, tal dificuldade pode ser contornada a partir da derivação de formas farmacêuticas sólidas, originando as chamadas preparações líquidas extemporâneas. Porém, para garantir o uso dos medicamentos após a alta hospitalar mesmo quando a família não pode pagar a manipulação destes, faz-se necessária uma orientação adequada de como realizar a derivação em casa pelo próprio cuidador do paciente. Objetivos: elaborar e avaliar um material educativo impresso (MEI) para auxiliar na preparação de medicamentos extemporâneos pós-alta hospitalar em pediatria. Métodos: Foi elaborada uma primeira versão de MEI e avaliada por 26 profissionais da saúde por meio do instrumento EVALPEM (Evaluation of Printed Education Materials) modificado. A partir das contribuições dos profissionais foi elaborada uma segunda versão avaliada por 5 cuidadores de crianças utilizando-se o questionário adaptado de Doak. Resultados: a primeira versão do MEI foi bem aceita pela maioria dos profissionais, onde 80,8% dos participantes consideraram as informações como sendo de qualidade e 87,5% concordaram totalmente com o domínio, legibilidade e características de impressão. A segunda versão obteve 89,1% no domínio compreensão, 90,6% em autoeficácia e 100% em atratividade, aceitação cultural e persuasão. Conclusões: o MEI demonstrou ser uma ferramenta importante para orientar o preparo

The frequent use of non-licensed or off-label drugs in pediatrics is a world problem that occurs due to the unavailability of appropriate pharmaceutical forms with proper doses to administration in children. During hospitalization, this difficulty can be avoided with the derivation of solid pharmaceutical forms, originating the so-called extemporaneous liquid preparations. Nevertheless, to guarantee the use of medication after hospital discharge – especially when the family cannot pay for its manipulation –, it is necessary to provide appropriate guidance to caregivers on how to prepare the derivation at home. Aim: to create and evaluate printed educational material (PEM) to help in the preparation of extemporaneous formulations after hospital discharge in pediatrics. Methods: a first version of the PEM was created and evaluated by 26 health workers, using the instrument EVALPEM (Evaluation of Printed Education Materials) modified. From the contribution of these professionals, a new version was developed and evaluated by five children caregivers, using an adaptation of the Doak questionnaire. Results: The first version of the PEM was well-accepted by most of the professionals, as 80.8% of them completely agreed about the quality of the information and 87.5% totally agreed about the legibility and printing features. The second version received 89.1% of approval in the field understanding, 90.6% in self-effectiveness, and 100% in atractiveness, cultural acceptance, and persuasion. Conclusions: The PEM proved to be an important tool to guide the correct preparation and administration of extemporaneous formulations by the caregivers of pediatric patients
