Indicators related to the rational use of medicines and its associated factors / Indicadores relacionados ao uso racional de medicamentos e seus fatores associados

ABSTRACT OBJECTIVE To evaluate indicators related to the rational use of medicines and its associated factors in Basic Health Units. METHOD This is a cross-sectional study carried out in a representative sample of Brazilian cities included in the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). The data were collected by interviews with users, medicine dispensing professionals, and prescribers; and described by prescription, dispensing, and health services indicators. We analyzed the association between human resources characteristics of pharmaceutical services and dispensing indicators. RESULTS At national level, the average number of medicines prescribed was 2.4. Among the users, 5.8% had antibiotic prescription, 74.8% received guidance on how to use the medicines at the pharmacy and, for 45.1% of users, all prescribed medicines were from the national list of essential medicines. All the indicators presented statistically significant differences between the regions of Brazil. The dispensing professionals that reported the presence of a pharmacist in the unit with a working load of 40 hours or more per week presented 1.82 more chance of transmitting information on the way of using the medicines in the dispensing process. CONCLUSION The analysis of prescription, dispensing, and health services indicators in the basic health units showed an unsatisfactory proportion of essential medicines prescription and limitations in the correct identification of the medicine, orientation to the patients on medicines, and availability of therapeutic protocols in the health services.

RESUMO OBJETIVO Avaliar indicadores relacionados ao uso racional de medicamentos e seus fatores associados em unidades básicas de saúde. MÉTODOS Estudo transversal realizado em amostra representativa de municípios do Brasil incluídos na Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015. Os dados foram coletados por meio de entrevista com usuários, profissionais dispensadores de medicamentos e prescritores; e descritos por meio de indicadores de prescrição, dispensação e de serviços de saúde. Realizou-se análise da associação entre características dos recursos humanos dos serviços farmacêuticos e indicadores de dispensação. RESULTADOS Em nível nacional, o número médio de medicamentos prescritos foi de 2,4. A proporção de usuários com prescrição de antibiótico foi de 5,8%, 74,8% dos usuários receberam orientações sobre medicamentos na farmácia e para 45,1% usuários todos os medicamentos prescritos eram da relação nacional de medicamentos essenciais. Todos os indicadores apresentaram variações estatisticamente significantes entre as regiões do Brasil. Os dispensadores que relataram a presença de farmacêutico na unidade com carga horária igual ou superior a 40 horas semanais apresentaram 1,82 mais chance de transmitir orientações sobre o modo de usar dos medicamentos no processo de dispensação. CONCLUSÕES A análise de indicadores de prescrição, dispensação e de serviços de saúde nas unidades básicas de saúde mostrou proporção insatisfatória de prescrição de medicamentos essenciais e limitações na identificação correta do medicamento, orientação aos pacientes sobre medicamentos e de disponibilidade de protocolos terapêuticos nos serviços de saúde.

Medicamentos potencialmente inapropriados para idosos / Potentially inappropriate medications in elderly

OBJETIVO: Comparar PRISCUS com Beers-Fick na detecção de medicamentos potencialmente inapropriados (MPI) para idosos à primeira consulta ambulatorial geriátrica. MÉTODOS: Análise retrospectiva de prontuários por PRISCUS e Beers-Fick adaptados à farmacopeia brasileira, comparando-se o encontro de MPI à primeira consulta ambulatorial geriátrica pelos dois critérios. RESULTADOS: Idade média de 77,4 ± 7,7 anos, 64 mulheres e 36 homens, consumo médio de 3,9 ± 2,5 fármacos. Este estudo encontrou significância estatística no número de mulheres em uso de benzodiazepínicos e de homens quanto a salicilatos. Média de 0,5 ± 0,7 MPI/paciente por Beers-Fick e 0,7 ± 0,8 MPI/paciente pela PRISCUS. Medicamentos de Beers-Fick mais referidos: benzodiazepínicos, metildopa e derivados do ergot. Medicamentos de PRISCUS mais referidos: benzodiazepínicos, anti-hipertensivos e antidepressivos tricíclicos. Não houve significância estatística comparando-se o número de idosos com MPI pelos dois critérios. Constatou-se significância estatística (PRISCUS versus Beers-Fick) no consumo de benzodiazepínicos de longa ação e laxantes. Ambos não incluem fármacos como vitaminas, fitoterápicos e colírios, relatados por percentual da casuística. CONCLUSÃO: Os dois critérios são úteis para a prevenção de MPI em idosos, sendo PRISCUS mais atualizada e abrangente, mas não são completos para a realidade ambulatorial brasileira.

OBJECTIVE: To compare PRISCUS with Beers-Fick in detecting potentially inappropriate medication (PIMs) in elderly at their first outpatient geriatric visit. METHODS: Retrospective medical record analysis by PRISCUS and Beers-Fick adapted to Brazilian pharmacopoeia, comparing the finding of PIMs at the first outpatient geriatric visit by both criteria. RESULTS: Cases had mean age of 77.4 ± 7.7 years (64 females and 36 males), and mean consumption of 3.9 ± 2.5 drugs. This study found statistical significance for the numbers of women using benzodiazepines and men using salicylates. The mean was 0.5 ± 0.7 PIMs/patient by Beers-Fick criteria and 0.7 ± 0.8 PIMs/patient by PRISCUS. Medications most often reported by Beers-Fick criteria were: benzodiazepines, methyldopa and ergot-derived drugs. Medications most often reported by PRISCUS criteria were: benzodiazepines, antihypertensive drugs, and tricyclic antidepressants. No statistical significance was found when the number of elderly patients with PIMs was compared between both criteria. Statistical significance was found (PRISCUS versus Beers-Fick) for the consumption of long acting benzodiazepines and laxatives. Both criteria do not include drugs such as vitamins, herbal medications, and eye drops, reported by a percentage of cases. CONCLUSION: Both criteria are useful to prevent PIMs in the elderly, with PRISCUS being more updated and comprehensive, but they are not complete for the Brazilian outpatient reality.

Utilização de medicamentos por gestantes usuárias do Sistema Único de Saúde no município de Santa Rosa (RS, Brasil) / Prescribed and unprescribed drug use among pregnant patients attended by the Unified Health System in Santa Rosa (State of Rio Grande do Sul, Brazil)

Com o objetivo de descrever o uso de medicamentos prescritos e não prescritos, realizou-se um estudo descritivo em gestantes em pré-natal no Sistema Único de Saúde (SUS) no município de Santa Rosa, Estado do Rio Grande do Sul. Os dados sobre o uso de medicamentos foram coletados através de entrevista estruturada e consulta aos prontuários das gestantes. A prevalência do uso de medicamentos foi de 90 por cento, correspondendo a uma média de uso de 4,1 medicamentos por gestante, dos quais 83,6 por cento foram prescritos e 16,4 por cento foram utilizados por automedicação. Do total de medicamentos, 17,5 por cento estão incluídos na categoria C de risco ao feto. O uso de medicamentos é frequente, e a maioria das gestantes utilizou um ou mais fármacos prescritos ou não prescritos. Esses dados sugerem a necessidade de medidas de intervenção para promover o uso racional de medicamentos durante a gestação.

In order to ascertain the use of prescribed and unprescribed drugs among pregnant patients of the Unified Health System (SUS), a descriptive study comprised of a sample of pregnant women was carried out in the city of Santa Rosa, State of Rio Grande do Sul, Brazil. Data were collected by means of structured interviews and consultation of patient records of pregnant women in the prenatal period. The prevalence of drug use was 90 percent, corresponding to an average of 4.1 drugs per pregnant woman, of which 83.6 percent were prescribed and 16.4 percent were self-medicated. Of this total, 17.5 percent of the drugs were included in fetal risk category C. The use of drugs during pregnancy is frequent and the majority of the pregnant women used one or more prescribed and unprescribed drugs during pregnancy. These data suggest the need for preventive measures to promote rational drug use during pregnancy.

Drug utilization patterns in pregnant women: a case study at the Mount Hope Women's Hospital in Trinidad, West Indies / Patrones de utilización de medicamentos en las mujeres embarazadas: un caso de estudio en el Hospital de Mujeres Mount Hope en Trinidad, West Indies

OBJECTIVE: To explore drug (prescription, over-the-counter and herbal) utilization in pregnant women attending a public sector tertiary healthcare institution. METHODS: This was a cross-sectional case study in women attending antenatal clinics at the Mount Hope Women's Hospital. Women (506) who consecutively presented for routine care at the antenatal clinic were interviewed on the medication they took. Descriptive statistics and logistic regression for predictors of drug use were done using SPSS 16. RESULTS: There were 200 (39.5%) primigravidae, 306 (60.5%) multigravidae and 299 (59%) women were in the third trimester of pregnancy. Most women (69.8%) were between 20-35 years of age. Women took an average of 1.32, 1.22 and 0.94 prescribed drugs in each trimester, respectively. Multivitamins (59.8%) and iron/folic acid (54.2%) were the most frequently prescribed drugs. Regardless of trimester, only 20% of women took supplemental calcium. Very few women (2.4%) took herbal medications. Paracetamol was the most common over-the-counter (OTC) medication in all trimesters. Women with secondary level education were most likely to use OTC iron/folic acid (p = 0.02), paracetamol and histamine2 receptor antagonists [H2RAs] (p = 0.001). More primigravidae took non-steroidal anti-inflammatory drugs (p = 0.02) and more women in the first trimester used antiemetics (p = 0.001). Age group (p = 0.048), marital status (p = 0.001) and the trimester of pregnancy (p = 0.001) were predictors of drug utilization. CONCLUSION: Overall, women in tertiary healthcare institutions took medication as prescribed particularly multivitamins and iron/folic acid. More women with higher education took OTC paracetamol, iron/folic acid and vitamin supplements. Herbal supplements were rarely used. Research on drug utilization in primary care facilities is recommended.

OBJETIVO: Explorar el uso de los medicamentos (con prescripción, sin receta médica, herbarios) en mujeres embarazadas que asisten a una institución terciaria de atención a la salud pública dentro del sector público. MÉTODOS: Se trató de un estudio transversal de mujeres que asisten a las clínicas prenatales en el Hospital de Mujeres Mount Hope. Las mujeres (506) que consecutivamente se presentaron para cuidados de rutina en la clínica prenatal, fueron entrevistadas acerca de la medicación que tomaban. Se hicieron estadísticas descriptivas y se hizo una regresión logística para los predictores del uso del medicamento usando SPSS 16. RESULTADOS: Había 200 (39.5%) primerizas, 306 (60.5%) multíparas, y 299 (59%) embarazadas en su tercer trimestre. La mayoría de las mujeres (69.8%) tenían entre 20-35 años de edad. Las mujeres tomaban un promedio de 1.32, 1.22 y 0.94 medicamentos prescritos en cada trimestre, respectivamente. Las multivitaminas (59.8%) y el hierro/ácido fólico (54.2%) fueron los medicamentos más frecuentemente prescritos. Con independencia del trimestre, sólo 20% de las mujeres tomaron suplemento de calcio. Muy pocas mujeres (2.4%) tomaban medicaciones herbarias. El paracetamol fue el medicamento sin receta más común en todos los trimestres. Las mujeres con nivel de educación secundaria presentaban una mayor probabilidad de usar hierro/ácido fólico (p = 0.02), el paracetamol y los antagonistas de los receptores de la histamina-2- [H2RAs] (p = 0.001). Un mayor número de primerizas tomaron medicamentos anti-inflamatorios no esteroideos (p = 0.02) y más mujeres en el primer trimestre usaron anti-eméticos (p = 0.001). El grupo etario (p = 0.048), el estado matrimonial (p = 0.001) y el trimestre de embarazo (p = 0.001) fueron predictores de la utilización de medicamentos. CONCLUSIÓN: En general, las mujeres en las instituciones terciarias de atención a la salud tomaron la medicación como fue prescrita, en particular las multivitaminas y el hierro/ácido fólico. Más mujeres con mayor escolaridad tomaron medicamentos sin recetas: paracetamol, hierro/ácido fólico y suplementos de vitamina. Raramente se usaron suplementos herbarios. Se recomienda la investigación del uso de medicamentos en centros de atención primaria.

Epidemiology of drug abuse treatment in South Africa

Background. The aim of the study was to explore the epidemiology of drug abuse treatment in South Africa. Methods. Treatment demand statistics were analysed from South African National Council on Alcoholism and Drug Dependence and the South African Community Epidemiology Network on Drug Use records; and a rapid situation assessment was conducted. Twenty-one key informant interviews were conducted in all 9 provinces among provincial substance abuse co-ordinators, and one manager per treatment centre from a sample of treatment centres. Three focus groups were conducted and 46 self-administered questionnaires were distributed among inpatients at 2 selected treatment centres in Free State and North West provinces. Qualitative data were analysed using grounded theory, and quantitative data analysed using SPSS. Results.Treatment records show that the most frequent substance of abuse was alcohol (51), followed by cannabis (21), crack/cocaine (9.6), heroin/opiates (7.9), methamphetamine (Tik) (4.5), prescription/over-thecounter drugs (2.0), and cannabis/mandrax (1.7). More substance abusers were male, of lower education, white or black, than were female, more highly educated; coloured and Indian/Asian. Key informant interviews showed that females are the 'hidden' substance abusers and tend not to be identified in research statistics and at treatment centres. Poverty, unemployment, lack of recreational facilities, being surrounded by substance abusers; and long work shifts were also mentioned as factors contributing to substance abuse. The age of initiation of substance abuse using non-drugs such as glue was 9 years old; alcohol 10 - 12 years old, dagga 11 -12 years old, poly-drug use (alcohol, tobacco and dagga) 14 years old, and harder drugs such as cocaine and heroin at 16 - 17 years old, as reported by key informants. Family care and support, improved socio-economic conditions and increased law enforcement would help to discourage substance abuse. Conclusion. Prevention interventions and policies in South Africa should focus on reducing substance abuse by targeting the 'at risk populations' identified in this study

Caracterização dos medicamentos prescritos aos idosos na Estratégia Saúde da Família / Characterization of drugs prescribed to the elderly in the Family Health Strategy

Considering that the elderly are heavy consumers of medications, with significant consequences for their living conditions, the current study was intended to analyze the characteristics of such drug prescription, using the indicators proposed by the World Health Organization (WHO), and to characterize the drug classes prescribed to them in four units under the Family Health Strategy (FHS) in Marília, São Paulo State, Brazil. One family health unit (FHU) was selected by region of the city, and 100 patient charts were checked in FHU-A; 86 in B, 99 in C, and 97 in D. According to WHO drug prescription criteria, the results were similar to the recommended patterns except for drug prescription by generic name. In addition, there were significant differences between the family health units. The most frequently prescribed drug classes were for cardiovascular disorders. The health professionals showed a concern for adjusting drug prescription to rational-use criteria. However, there is a need for understanding the differences in prescription between units and a search for consensus, aimed at rational drug use.

Considerando que os idosos são grandes consumidores de medicamentos, com conseqüências significativas em sua condição de vida, propomos para o presente estudo analisar as características da prescrição de medicamentos, utilizando os indicadores propostos pela Organização Mundial da Saúde (OMS) e caracterizar as classes medicamentosas prescritas a eles, em quatro unidades da Estratégia Saúde da Família (ESF) de Marília, São Paulo, Brasil. Foi sorteada uma unidade de saúde da família (USF) por região da cidade e verificaram-se 100 prontuários na USF A; 86 na B, 99 na C e 97 na D. Quanto aos indicadores de prescrição de medicamentos da OMS, os resultados apresentam semelhanças com os padrões recomendados, exceto quanto à prescrição de medicamentos pelo nome genérico. Além disso, há diferenças significativas entre as unidades. As classes medicamentosas mais prescritas são aquelas destinadas aos problemas do sistema cardiocirculatório. Revela-se preocupação dos profissionais em adequar a prescrição de medicamentos a critérios de uso racional. Há, no entanto, necessidade de compreensão das diferenças de prescrição entre as unidades e busca de consenso, visando ao uso racional de medicamentos.
