MÉTODOS: Estudio descriptivo basado en encuestas telefónicas a una muestra aleatoria de pacientes adultos del nivel primario de salud del sistema público español. Respondieron un total de 1 247 pacientes (tasa de respuesta, 75%). El 63% eran mujeres y 29% eran mayores de 70 años. RESULTADOS: Mientras 37 pacientes (3%, IC 95%: 2-4) sufrieron complicaciones asociadas a la medicación en el curso del tratamiento, 241 (19,4%, IC 95%: 17-21) informaron haber cometido algún error con la medicación. Un menor tiempo de consulta (P < 0,01) y una peor valoración de la información proporcionada por el médico (P < 0,01) se asociaron al hecho de que en la dispensación en la farmacia le indicaran al paciente que el tratamiento prescrito no era apropiado. CONCLUSIONES: A los riesgos conocidos de sufrir un evento adverso, fruto de la intervención sanitaria por error del sistema o del profesional, hay que sumar los asociados a los errores de los pacientes en la autoadministración de la medicación. Los pacientes insatisfechos con la información proporcionada por el médico informaron un mayor número de errores.<hr/>OBJECTIVE: Analyze the frequency of medication errors committed and reported by patients. METHODS: Descriptive study based on a telephone survey of a random sample of adult patients from the primary care level of the Spanish public health care system. A total of 1 247 patients responded (75% response rate); 63% were women and 29% were older than 70 years. RESULTS: While 37 patients (3%, 95% CI: 2-4) experienced complications associated with medication in the course of treatment, 241 (19.4%, 95% CI: 17-21) reported having made some mistake with their medication. A shorter consultation time (P < 0.01) and a worse assessment of the information provided by the physician (P < 0.01) were associated with the fact that during pharmacy dispensing the patient was told that the prescribed treatment was not appropriate. CONCLUSIONS: In addition to the known risks of an adverse event due to a health intervention resulting from a system or practitioner error, there are risks associated with patient errors in the self-administration of medication. Patients who were unsatisfied with the information provided by the physician reported a greater number of errors. <![CDATA[<b>Population study of depressive symptoms and risk factors in pregnant and parenting Mexican adolescents</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200002&lng=en&nrm=iso&tlng=en OBJECTIVE: To study the prevalence of, severity of, and risk factors for depressive symptoms in a probabilistic sample of Mexican adolescent mothers. METHODS: A sample of adolescents aged 13-19 years, drawn from a national survey, was interviewed in relation to severity of depressive symptoms [Center for Epidemiological Studies Depression Scale (CES-D) 16-23 and CES-D > 24] and pregnancy or parenting status. RESULTS: Depressive symptoms (CES-D 16-23) ranged from 2.3% in the first postpartum semester to 32.5% in the second trimester of pregnancy; high depressive symptoms (CES-D > 24) ranged from 3.0% in the second postpartum semester to 24.7% in mothers of an infant more than 1 year old. Significant differences between groups were in mothers in the second gestation trimester, who had significantly more symptoms than those who had never been pregnant and those in the first postpartum semester. In those with high symptomatology, no significant differences were observed between groups. A multinomial logistic regression model used to estimate the likelihood of depression found increased risk of depressive symptoms (CES-D 16-23) in those without a partner in the first, second, or third trimester of pregnancy; in the second postpartum semester; and with a child over the age of 1 year. Increased risk of high symptomatology (CES-D > 24) was found in those not in school or with a child over the age of 1 year. CONCLUSIONS: Depressive symptoms entail an enormous burden of disease for the mother and mental health risks to the infant; mothers should therefore be targeted in prevention and intervention actions.<hr/>OBJETIVO: Estudiar la prevalencia, la gravedad y los factores de riesgo de los síntomas depresivos en una muestra probabilística de madres adolescentes de México. MÉTODOS: En una muestra de adolescentes de 13 a 19 años de edad tomadas de una encuesta nacional se efectuaron entrevistas relacionadas con la gravedad de los síntomas depresivos (Center for Epidemiological Studies Depression Scale [CES-D] 16 a 23 y CES-D > 24) y la situación de embarazo o de crianza. RESULTADOS: Los síntomas depresivos (CES-D de 16 a 23) variaron de 2,3% en el primer semestre después del parto a 32,5% en el segundo trimestre del embarazo; los síntomas depresivos graves (CES-D > 24) fueron desde 3,0% en el segundo semestre posparto hasta 24,7% en las madres de un niño mayor de 1 año de edad. Se observaron diferencias significativas entre los grupos en las madres que se encontra-ban en el segundo trimestre de la gestación, que presentaron significativamente más síntomas que las mujeres que nunca habían estado embarazadas y que las que estaban en el primer semestre posparto. En las mujeres con síntomas graves, no se observaron diferencias significativas entre los grupos. Mediante un modelo de regresión logística polinómico usado para calcular la probabilidad de depresión se detectó un mayor riesgo de padecer síntomas depresivos (CES-D 16 a 23) en las mujeres sin una pareja que se encontraban en el primer, segundo o tercer trimestre del embarazo; en el segundo semestre después del parto; y en las mujeres con un niño mayor de 1 año. En las mujeres que no concurrían a la escuela y en aquellas con un niño mayor de 1 año se encontró un mayor riesgo de presentar síntomas graves (CES-D > 24). CONCLUSIONES: Los síntomas depresivos implican una carga de morbilidad impor-tante para la madre y riesgos para la salud mental del lactante; por lo tanto, las acciones de prevención y de intervención deben dirigirse a las madres. <![CDATA[<b>Registration of work-related diseases, injuries, and complaints in Aruba, Bonaire, and Curaçao</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200003&lng=en&nrm=iso&tlng=en OBJECTIVE: To estimate the incidence of work-related diseases, injuries, and complaints in Aruba, Bonaire, and Curaçao and to identify some next steps in the prevention process. METHODS: All of the three countries' 18 occupational health specialists were asked to participate; 100% agreed to report all work-related diseases, injuries, and complaints in 2004-2008. A standard online notification form was used to register cases in a database maintained by the Netherlands Center for Occupational Diseases (NCOD). The public health service of Curaçao analyzed the data and presented the results to the participating physicians during educational and feedback meetings. RESULTS: During the study period, 1 519 cases were reported: 720 (47.0%) work-related diseases; 515 (34.0%) injuries; and 284 (19.0%) complaints. The mean patient age was 42.4 years (range 16-70 years); 924 (60.8%) were males and 571 (37.6%), females. Most frequently reported were musculoskeletal diseases, injuries, and complaints; mental health disorders; and skin injuries. Analysis showed incidence rates of work-related diseases, injuries, and complaints in Aruba to be 157 new cases per 100 000 employee years; in Bonaire, 53/100 000; and in Curaçao, 437/100 000. CONCLUSIONS: These results suggest that labor protection laws need improvement and that preventive action should be fostered. Further study is needed on working conditions, preventive policy, and the quality of occupational health and safety practices in Aruba, Bonaire, and Curaçao. Funding is imperative for collecting and publishing accurate data, which will keep this problem on the social-political agenda.<hr/>OBJETIVO: Calcular la incidencia de enfermedades, lesiones y síntomas relacionados con el trabajo en Aruba, Bonaire y Curazao e identificar los pasos siguientes en el proceso de prevención. MÉTODOS: Se invitó a participar a los 18 especialistas en salud ocupacional de los tres países; todos aceptaron notificar todas las enfermedades, lesiones y síntomas relacionados con el trabajo entre el 2004 y el 2008. Se usó un formulario estándar de notificación en línea para registrar los casos en una base de datos mantenida por el Centro para las Enfermedades Ocupacionales de los Países Bajos. El servicio de salud pública de Curazao analizó los datos y presentó los resultados a los médicos participantes durante las reuniones educativas y de retroalimentación. RESULTADOS: Durante el período del estudio se notificaron 1 519 casos relacionados con el trabajo: 720 (47,0%) enfermedades, 515 (34,0%) lesiones y 284 (19,0%) síntomas. La edad promedio de los pacientes fue 42,4 años (recorrido, 16-70 años); 924 (60,8%) eran varones y 571 (37,6%), mujeres. Se notificaron con mayor frecuencia las enfermedades, lesiones y síntomas musculoesqueléticos; los trastornos mentales; y las lesiones cutáneas. El análisis mostró tasas de incidencia de enfermedades, lesiones y síntomas relacionados con el trabajo de 157 nuevos casos por 100 000 empleados por año en Aruba, 53/100 000 en Bonaire y 437/100 000 en Curazao. CONCLUSIONES: Estos resultados indican que las leyes de protección laboral deben mejorarse y que deben promoverse las medidas preventivas. Es necesario llevar a cabo otros estudios sobre las condiciones de trabajo, los planes de prevención y la calidad de la salud ocupacional y las prácticas de seguridad en Aruba, Bonaire y Curazao. Se requiere financiamiento para recopilar y publicar datos exactos, a fin de mantener este problema en la agenda política y social. <![CDATA[<b>Health promotion education in the context of primary care</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200004&lng=en&nrm=iso&tlng=en OBJETIVO: Investigar se as práticas educativas realizadas nas unidades básicas de saúde de Belo Horizonte, Estado de Minas Gerais, Brasil, atendem aos princípios da promoção da saúde. MÉTODOS: Este estudo descritivo analisou 33 práticas educativas de promoção da saúde para verificar se eram pautadas por cinco princípios, utilizados como categoria de análise: multicausalidade do processo saúde-doença, intersetorialidade, participação social, sustentabilidade e utilização de métodos dialógicos (participação ativa do sujeito na prática educativa, condução da prática de forma a proporcionar a construção do conhecimento e utilização de diferentes estratégias de ensino). A técnica utilizada foi a observação estruturada. Determinou-se a frequência de cada uma dessas categorias nas práticas avaliadas. RESULTADOS: A multicausalidade do processo saúde-doença foi a categoria mais incorporada às práticas educativas (73,0%), enquanto a intersetorialidade foi a menos incorporada (9,0%). Quanto ao uso de métodos dialógicos, 38,0% das práticas promoveram a participação ativa do sujeito, 6,0% proporcionaram a construção do conhecimento e 40,0% utilizaram diferentes estratégias de ensino. CONCLUSÕES: A maioria das práticas educativas não estava orientada ativamente em direção à promoção da saúde no sentido de fortalecimento da autonomia na gestão dos processos de saúde, da participação social e do emprego de abordagens dialógicas de ensino. Entretanto, observam-se movimentos de ruptura em relação aos modelos de educação hegemônicos na atenção primária.<hr/>OBJECTIVE: To investigate whether the educational initiatives carried out in basic health units in Belo Horizonte, Minas Gerais, Brazil, follows the principles of health promotion. METHODS: This descriptive study examined 33 educational health promotion initiatives to determine whether they were guided by five principles, used as categories of analysis: multicausality of the health-disease process, intersectoriality, social engagement, sustainability, and use of dialogic teaching methods (active participation of subjects in the learning process, planning the activity to generate new knowledge, and use of various teaching strategies). Structured observation was used for data collection. The frequency of each category was evaluated in each initiative. RESULTS: Multicausality was the most frequent category observed (73.0%), and intersectoriality the least frequent (9.0%). Regarding the use of dialogic methods, 38.0% of the initiatives promoted the active engagement of subjects, 6.0% promoted knowledge generation, and 40.0% employed a variety of teaching strategies. CONCLUSIONS: Most educational initiatives were not actively oriented toward health promotion, understood as the strengthening of autonomy and self-management of health processes, social engagement, and employment of dialogic teaching approaches. However, some progress has been made moving away from hegemonic models of education in primary health care. <![CDATA[<b>Predictive factors for repetition of the tuberculin test after a nonreactive test in patients with HIV/AIDS</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200005&lng=en&nrm=iso&tlng=en OBJECTIVE: The outcome of interest was repetition of the tuberculin skin test (TST) and the objectives were to estimate the rate of TST repetition, the probability of no TST repetition after 1 year, and the probability of no TST repetition at the end of the follow-up period in patients whose initial test was nonreactive. The study also set out to analyze factors associated with the time until TST repetition at two HIV/AIDS referral services that carry out the TST on a routine basis in Recife, Pernambuco, Brazil. METHODS: A cohort of HIV-positive patients who initially tested nonreactive on the TST were followed from November 2007 to February 2010. The Kaplan-Meier method was used to estimate the probability of not repeating the TST, and Cox's regression analysis was used to analyze the factors associated with time until repeating the TST. Cox's multivariate analysis was stratified according to each hospital where patients were followed, because this variable did not respect the principle of proportionality of risk. RESULTS: The probability of not repeating the TST for 1 year was 80.0% and at the end of the follow-up period it was 42.0%. The variables that remained associated with TST repetition in the final Cox multivariate model were an age of 40 years or older, body mass index between 18.0 and 24.9, being female, and years of schooling. CONCLUSIONS: This study encountered a very low TST repetition rate after 1 year of follow-up and identified groups of individuals who should be the target of interventions aimed at repeating the TST.<hr/>OBJETIVO: El resultado principal de interés fue la repetición de la prueba de la tuberculina (PT) y los objetivos fueron calcular la tasa de repetición de la PT, la probabilidad de no repetir la PT después de un año y la probabilidad de no repetir la PT al final del período de seguimiento en los pacientes cuya prueba inicial fue no reactiva. En el estudio también se analizaron los factores asociados con el tiempo hasta la repetición de la PT en dos servicios de referencia de infección por el VIH/sida que llevan a cabo la PT de manera sistemática en Recife, Pernambuco, Brasil. MÉTODOS: Entre noviembre del 2007 y febrero del 2010 se siguió a una cohorte de pacientes seropositivos para el VIH con una PT inicialmente no reactiva. Para calcular la probabilidad de no repetir la PT se empleó el método de Kaplan-Meier, y para analizar los factores asociados con el tiempo hasta la repetición de la PT se usó el análisis de regresión de Cox. El análisis multifactorial de Cox se estratificó conforme a cada hospital donde se seguía a los pacientes, dado que esta variable no respetaba el principio de proporcionalidad del riesgo. RESULTADOS: La probabilidad de no repetir la PT durante un año fue de 80,0% y hacia el final del período de seguimiento fue de 42,0%. Las variables asociadas con la repetición de la PT en el modelo multifactorial de Cox final fueron una edad de 40 años o más, un índice de masa corporal de 18,0 a 24,9, el sexo femenino y los años de escolaridad. CONCLUSIONES: En este estudio se encontró una tasa de repetición de la PT muy baja después de un año de seguimiento y se identificó a los grupos de individuos que deben ser los destinatarios de las intervenciones dirigidas a repetir la prueba de la tuberculina. <![CDATA[<b>Preliminary reliability and validity of the spanish generalized expectancies for negative mood regulation scale</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200006&lng=en&nrm=iso&tlng=en OBJECTIVE: This article introduces a Spanish version of the Generalized Expectancies for Negative Mood Regulation Scale (NMR-S) and tests the reliability and the validity of the new questionnaire. METHODS: A sample of 360 students from Chile completed the NMR-S along with instruments measuring depressive symptoms, social desirability, coping, and emotion regulation. RESULTS: A factor analysis indicated that the NMR-S has a one-dimensional structure. The reliability of the new instrument was α = 0.89. The concurrent validity of the NMR-S was supported by correlations with measures of coping, emotion regulation, and depressive symptoms. Furthermore, the NMR-S predicted depressive symptoms when controlling for emotion regulation and coping. CONCLUSIONS: The findings are the first evidence to support the reliability and validity of the NMR-S.<hr/>OBJETIVO: En este artículo se presenta la versión en español de la Escala de Expectativas Generalizadas para la Regulación del Animo Negativo (NMR-S) y se evalúa la confiabilidad y la validez del nuevo cuestionario. MÉTODOS: Una muestra de 360 estudiantes de Chile completó la NMR-S junto con instrumentos dirigidos a medir síntomas depresivos, deseabilidad social, afrontamiento y regulación emocional. RESULTADOS: Un análisis factorial indicó que la NMR-S tiene una estructura unidimensional. La confiabilidad del nuevo instrumento fue de α = 0,89. La validez concurrente de la NMR-S fue avalada a través de su correlación con las mediciones de afrontamiento, regulación emocional y síntomas depresivos. Asimismo, la NMR-S predijo los síntomas depresivos cuando se controló por la regulación emocional y el afrontamiento. CONCLUSIONES: Los datos presentados son la primera evidencia para avalar la confiabilidad y la validez de la NMR-S. <![CDATA[<b>Racial inequity in oral health in Brazil</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200007&lng=en&nrm=iso&tlng=en OBJETIVO: Identificar iniquidades raciais em saúde bucal entre grupos de pessoas adultas autodeclaradas como brancas, pretas ou pardas no Brasil. MÉTODOS: Foram utilizados dados secundários obtidos da base de dados da pesquisa nacional sobre a condição de saúde bucal da população brasileira (SB Brasil 2002-2003). Inicialmente, foi realizado um estudo transversal para comparar as variáveis de desfecho cárie, perda dental, dor de origem dentária e necessidade de prótese por grupo de raça/cor para uma amostra de 12 811 adultos de ambos os sexos, na faixa etária de 35 a 44 anos. Na segunda etapa, realizou-se um estudo ecológico com dados agregados por estado brasileiro para contextualizar as iniquidades raciais para uma população de 6 918 negros, agregando pretos e pardos, analisando a correlação entre os desfechos em saúde bucal estudados na primeira fase e os indicadores de desenvolvimento humano e concentração de renda. RESULTADOS: Diferenças significativas foram observadas entre os grupos de raça/cor para todos os desfechos de saúde bucal analisados (P < 0,01). Foram encontradas correlações entre desfechos em saúde bucal e indicadores ligados ao perfil de desenvolvimento humano, renda média familiar e desigualdade de renda por estado brasileiro para o grupo de negros. CONCLUSÕES: Os resultados evidenciaram iniquidades raciais em saúde bucal no Brasil em todos os indicadores analisados (cárie, perda dentária, dor e necessidade de prótese), com maior vulnerabilidade da população negra (pretos e pardos) em relação aos brancos. Fatores contextuais relacionados ao perfil de desenvolvimento humano, à distribuição de renda e ao acesso a políticas de cuidado em saúde parecem ter papel essencial na caracterização da vulnerabilidade de grupos populacionais a agravos em saúde bucal.<hr/>OBJECTIVE: To identify racial inequities in oral health between groups of adults selfdeclared as white, black, or mixed in Brazil. METHODS: Secondary data were obtained from the national oral health survey of the Brazilian population (SB-Brasil 2002-2003) database. Initially, a cross-sectional study was conducted to compare the following outcome variables: caries, tooth loss, pain of dental origin, and need for prostheses according to race/color in a sample of 12 811 adults of both sexes, aged 35 to 44 years. In the second stage, an ecologic study was carried out with data aggregated by Brazilian state to contextualize racial inequity in a population of 6 918 black individuals (black and mixed). For that, the oral health outcomes studied in the first stage were correlated with human development and income distribution indicators. RESULTS: Significant differences were observed between the race/color groups for all oral health outcomes examined (P < 0.01). Correlations were found between oral health outcomes and indicators related to the human development profile, average family income, and income inequality by state for the group of Brazilian blacks. CONCLUSIONS:The results show racial inequity in oral health in Brazil for all the indicators analyzed (caries, tooth loss, pain, and need for prostheses), with greater vulnerability among the black population compared to whites. Contextual factors related to the human development profile, income distribution, and access to health care policies appear to play a key role in describing the vulnerability of populations to oral health problems. <![CDATA[<b>Diarrheal disease caused by rotavirus in epidemic outbreaks</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200008&lng=en&nrm=iso&tlng=en OBJETIVO: Determinar el perfil epidemiológico de los brotes de enfermedad diarreica aguda por rotavirus (RV) ocurridos en pacientes pediátricos, mediante una revisión crítica de la literatura publicada entre 2000 y 2010. MÉTODOS: Se realizó una búsqueda de artículos publicados desde enero de 2000 hasta abril de 2010, recogidos por las bases de datos Artemisa, EBSCO, Embase, Imbiomed, Lilacs, Ovid, PubMed y Science Direct. En los estudios que cumplieron con los criterios de inclusión, se identificaron posibles factores de confusión y se atribuyeron riesgos de sesgo con base en el número de ítems considerados inadecuados en cada caso. Se describieron las características epidemiológicas y microbiológicas de los brotes. RESULTADOS: Solo 14 (10,8%) de los 129 títulos identificados formaron parte de la muestra, los cuales sumaron 91 092 casos de diarrea aguda notificados. En 5 250 de estos casos se realizó la búsqueda de RV, la cual arrojó 1 711 (32,5%) aislamientos positivos. Se observó que el RV del grupo A fue el agente causal en 100% de los brotes, mientras que el genotipo G9 fue documentado en 50% de los artículos. CONCLUSIONES: El RV, principalmente el serotipo G9, fue uno de los principales agentes responsables de los brotes de EDA en la última década. Un cuidadoso estudio de brote puede aportar información valiosa para el control y la prevención de la enfermedad por RV.<hr/>OBJECTIVE: Determine the epidemiological profile of outbreaks of acute diarrheal disease caused by rotavirus (RV) occurring in pediatric patients, based on a critical review of the literature published between 2000 and 2010. METHODS: A search was carried out for articles published from January 2000 to April 2010, collected by the Artemisa, EBSCO, Embase, Imbiomed, Lilacs, Ovid, PubMed, and Science Direct databases. In the studies that met the inclusion criteria, possible confounding factors were identified and risks of bias were attributed based on the number of items considered inadequate in each case. The epidemiological and microbiological characteristics of the outbreaks were described. RESULTS: The sample was comprised of only 14 (10.8%) of the 129 titles identified, which accounted for 91 092 reported cases of acute diarrhea. In 5 250 of these cases, a search for rotavirus was conducted, yielding 1 711 (32.5%) positive isolations. It was observed that the RV from Group A was the causative agent in 100% of the outbreaks, while genotype G9 was documented in 50% of the articles. CONCLUSIONS: Rotavirus, mainly serotype G9, was one of the principal agents responsible for outbreaks of acute diarrheal disease over the past decade. A careful outbreak study can contribute valuable information for RV disease control and prevention. <![CDATA[<b>Atraumatic restorative treatment</b>: <b>a dental alternative well-received by children</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200009&lng=en&nrm=iso&tlng=en El presente estudio se propuso comparar la práctica restaurativa atraumática (PRAT) con el método tradicional (MT) rotacional, con el objetivo de determinar en ambos casos el tiempo total del procedimiento, el costo, la presencia de dolor y el comportamiento en pacientes pediátricos de Perú. De los 30 niños y niñas seleccionados para el estudio, la mitad fueron sometidos a la PRAT y restauración con cemento de ionómero de vidrio y la otra mitad fueron tratados con el MT y restauración con amalgama. Los parámetros de análisis fueron los tiempos necesarios para remover el tejido cariado y el procedimiento operatorio total, el costo total del procedimiento, la manifestación de dolor y el comportamiento del paciente durante el tratamiento. Se hallaron diferencias significativas entre ambas técnicas en todos los parámetros, excepto en el comportamiento del paciente. Si bien la remoción del tejido cariado con el MT fue más rápida, el procedimiento completo fue más rápido en la PRAT, que además resultó significativamente menos costosa y menos dolorosa que el MT. Los resultados indicaron que la PRAT es una muy buena alternativa por su bajo costo y aceptación por parte de los niños.<hr/>The purpose of this study is to compare atraumatic restorative treatment (ART) with the conventional rotational restorative method (CM) to determine in both cases the total time required for the procedure, the cost, the presence of pain, and the behavior of pediatric patients in Peru. Of the 30 children selected for the study, half received ART and restoration with glass ionomer cement and the other half, CM and restoration with amalgam. The study parameters were the times required to remove the decayed tissue and to complete the entire procedure, the total cost of the procedure, the presence of pain, and the patient's behavior during treatment. Significant differences were found between the two techniques in all parameters, except for the patient's behavior. Although removing the decayed tissue was faster with the CM, the entire procedure was faster with ART, which, moreover, was significantly less expensive and less painful than the CM. The results indicated that ART is a very good alternative due to its low cost and acceptance by the children. <![CDATA[<b>Share of health care ­activities in the Brazilian ­economy</b>: <b>information on Health Accounts from 2000 to 2007</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200010&lng=en&nrm=iso&tlng=en OBJETIVO: Descrever a participação das atividades de saúde na economia brasileira entre 2000 e 2007 em termos de valor adicionado e geração de postos de trabalho. MÉTODOS: Foram utilizados dados secundários do Instituto Brasileiro de Geografia e Estatística para os anos de 2000 a 2007. Foram analisadas as seguintes atividades: saúde pública, produção de serviços de saúde e serviços sociais privados, planos de saúde, indústria farmacêutica, indústria de equipamentos médicos e comércio de produtos farmacêuticos. Foi calculada a participação de cada atividade no total da economia e no setor saúde, a participação percentual dos componentes do valor adicionado na ótica da renda para as atividades de saúde e o crescimento real do valor adicionado por atividade de saúde. Para complementar as análises, foram levantados os rendimentos médios do trabalho e o número de postos de trabalho por atividade. RESULTADOS: A participação do setor saúde na economia variou de 5,2 a 5,8%. Cresceu a participação da saúde pública (de 1,7 para 2,0%) e caiu a dos serviços de saúde privados (de 2,4 para 2,2%). O crescimento médio anual do setor (3,5%) foi próximo ao da economia (3,4%). A participação do comércio de produtos farmacêuticos no setor aumentou de 9,1 para 13,2%. As atividades com maior crescimento acumulado foram: fabricação de aparelhos médico-hospitalares (42,7%), saúde pública (39,4%) e planos e seguros de saúde (35,8%). A saúde representou 4,1% dos postos de trabalho da economia em 2000 e 4,4% em 2007, com 1 milhão de novos postos. Os rendimentos do trabalho representaram 6,7% do total da economia em 2000 e 7,5% em 2007. CONCLUSÕES: O setor saúde tem uma participação importante na economia brasileira, embora essa participação ainda seja inferior àquela observada em países de alta renda. O aumento da participação dos serviços públicos no valor adicionado setorial, o crescimento das margens de comercialização dos produtos farmacêuticos e o crescimento real inferior à média setorial da indústria farmacêutica devem ser monitorados.<hr/>OBJECTIVE: To describe the share of health care activities in the Brazilian economy between 2000 and 2007 in terms of economic value added and creation of jobs. METHODS: Secondary data from the Brazilian Institute of Geography and Statistics (IBGE) for the years 2000 to 2007 were employed. The following health care activities were analyzed: public health, production of private health services and private social services, health insurance, the pharmaceutical industry, medical equipment manufacturing, and medical and pharmaceutical product sales. The share of each activity in the total economy and in the health care sector was calculated, as well as the percentage share of value-added components from the perspective of income for health care ­activities and the real growth in value added by health care activity. To complement the analysis, the average income of workers and the number of jobs per activity were ­established. RESULTS>: The participation of the health care sector in the economy ranged from 5.2% to 5.8%. The share of public health increased from 1.7% to 2.0%, and that of private healthcare services fell from 2.4% to 2.2%. The average annual growth of 3.5% for the sector was close to the 3.4% annual growth recorded for the economy. The share of medical and pharmaceutical product commerce in the sector increased from 9.1% to 13.2%. The activities with the highest accumulated growth were: manufacture of medical/hospital devices (42.7%), public health (39.4%), and health insurance (35.8%). Health care represented 4.1% of jobs in the economy in 2000 vs. 4.4% in 2007, with 1 million new jobs. Income from labor represented 6.7% of the total economy in 2000 and 7.5% in 2007. CONCLUSIONS: The health care sector has an important stake in the Brazilian economy, although this share is still lower than that observed in high-income countries. The rising share of public services in the sector’s added value, the relative growth of medical and pharmaceutical product sales margins, and a real growth below the average for the pharmaceutical industry should be monitored. <![CDATA[<b>Health</b>: <b>an adaptive complex system</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200011&lng=en&nrm=iso&tlng=en Este artículo destaca la enorme distancia existente entre el pensamiento complejo de índole intelectual, difundido en nuestro medio, y el pensamiento complejo de índole experimental, que ha permitido lograr los desarrollos científico-tecnológicos que han cambiado radicalmente el mundo. Invita a considerar como sistemas complejos adaptativos entidades tales como la vida, el ser humano, la sociedad global y todo aquello que se llama salud, para lo cual resulta prioritario adoptar un enfoque diferente que amplíe su conocimiento. Al reconocer esta racionalidad, se sustentan las principales características y propiedades emergentes de la salud como sistema complejo adaptativo, siguiendo un modelo de prestación de cuidados y servicios. Finalmente, se plantean algunas preguntas de investigación pertinentes desde esta perspectiva, y se expresan una serie de apreciaciones que se espera sirvan para comprender todo lo que como individuos y como especie hemos llegado a ser. Se propone en este trabajo que la salud y la prestación de servicios de asistencia sanitaria se consideren como sistemas complejos adaptativos.<hr/>This article points out the enormous gap that exists between complex thinking of an intellectual nature currently present in our environment, and complex experimental thinking that has facilitated the scientific and technological advances that have radically changed the world. The article suggests that life, human beings, global society, and all that constitutes health be considered as adaptive complex systems. This idea, in turn, prioritizes the adoption of a different approach that seeks to expand understanding. When this rationale is recognized, the principal characteristics and emerging properties of health as an adaptive complex system are sustained, following a care and services delivery model. Finally, some pertinent questions from this perspective are put forward in terms of research, and a series of appraisals are expressed that will hopefully serve to help us understand all that we have become as individuals and as a species. The article proposes that the delivery of health care services be regarded as an adaptive complex system. <![CDATA[<b>Social class and health in Latin America</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200012&lng=en&nrm=iso&tlng=en Se repasan los principales conceptos de clase social, ocupación y estratificación social, y su contribución al análisis de los determinantes sociales de la salud (DSS), y se revisan los estudios empíricos desarrollados en América Latina que utilicen las relaciones de empleo como DSS. La revisión se ha enfocado en los estudios sobre la relación entre salud y clase social basados en las perspectivas neoweberiana o neomarxista. La búsqueda en la Biblioteca Virtual en Salud de BIREME y en la base de datos SciELO permitió localizar 28 artículos de esas características. Esta relativa escasez contrasta con la abundancia de trabajos con tales enfoques realizados en Europa y en los Estados Unidos, con una larga tradición en el análisis de los DSS. En tal sentido, las implicaciones políticas y programáticas de la investigación sobre clase social y relaciones de empleo son diferentes y complementarias de los estudios de gradientes de salud asociados a los ingresos y la educación. La globalización en las relaciones de empleo exige nuevos conceptos para explicar y medir los mecanismos de acción de los DSS trascendiendo lo estrictamente laboral; en particular, la relevancia en la realidad latinoamericana actual del impacto del trabajo informal sobre la salud.<hr/>This paper reviews the principal concepts of social class, occupation, and social stratification, and their contribution to the analysis of the social determinants of health (SDH), and reviews empirical studies conducted in Latin America that use employment relations as an SDH. The review focuses on studies of the relationship between health and social class based on neo-Weberian or neo-Marxist perspectives. A search of the BIREME Virtual Health Library and the SciELO database found 28 articles meeting these characteristics. This relative dearth contrasts with the profusion of papers that use these approaches written in Europe and in the United States, with a long tradition in the analysis of SDH. In this regard, the political and programmatic implications of research on social class and employment relations are different from and complementary to studies of health gradients associated with income and education. Globalization of employment relations requires the development of new concepts to explain and measure the mechanisms of action of the SDH going beyond what is strictly labor related; in particular, the importance in the current Latin American reality of the impact of informal work on health. <![CDATA[<b>Hospitals safe from disasters</b>: <b>a reflection on architecture and biosafety</b>]]> http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S1020-49892012000200013&lng=en&nrm=iso&tlng=en Um dos maiores desafios da sociedade atual é o enfrentamento das adversidades causadas pelos desastres. Os estabelecimentos de saúde, principalmente os hospitais, são considerados essenciais nessas situações. Este trabalho discute os princípios da arquitetura do hospital seguro frente aos desastres, como propõem a Organização Mundial da Saúde e a Organização Pan-Americana da Saúde. Projetar um hospital seguro exige ações multidisciplinares, com envolvimento de administradores, arquitetos, engenheiros, médicos e enfermeiros. O planejamento de cada hospital pressupõe uma análise de riscos e aspectos de segurança específicos. Também é importante agregar a biossegurança ao conceito de hospital seguro. O equilíbrio entre aspectos arquitetônicos e biossegurança permite a compreensão dos riscos associados ao trabalho, facilitando o dimensionamento de espaços para suportar as ações de resposta frente às emergências. Em suma, a programação de um hospital seguro requer uma síntese de conhecimentos que relacionam diversos saberes, entre eles os da biossegurança e da arquitetura hospitalar. Esses princípios devem embasar as indagações sobre o hospital seguro e o planejamento de projetos arquitetônicos com foco na manutenção das instalações em capacidade máxima mesmo diante de situações adversas.<hr/>One of the biggest challenges in today’s society is facing adversity caused by disasters. Health facilities, especially hospitals, are considered essential in these situations. This article discusses the principles of architectural design of hospitals safe from disasters, as proposed by the World Health Organization and the Pan American Health Organization. Designing a safe hospital requires multidisciplinary efforts, involving administrators, architects, engineers, physicians, and nurses. The planning of each hospital demands the analysis of specific risks and safety concerns. The concept of biosafety should also be addressed in planning safe hospitals. The balance between architectural aspects and biosafety provides an understanding of work-associated risks, facilitating the adequate planning of spaces to support response actions to emergencies. In short, the planning of a safe hospital requires the synthesis of various types of expertise, including those relating to biosafety and architecture. These principles should support the appraisal of safe hospitals and architectural planning with a focus on preparing facilities to function at full capacity even in the face of adverse situations.
