RESUMO

BACKGROUND: The long-standing underrepresentation of women in leadership positions in medicine is well-known, but poorly documented globally. There is some evidence of the gender gap in academia, medical society leadership, or specific problems in some specialties. However, there are no investigations analyzing all medical specialties together and reporting the glass ceiling from a 360º perspective that includes positions in academia, research, professional organizations, and clinical activity. Additionally, the majority of studies have a US perspective, and we wonder if the perspective of a European country might be different. The WOmen in MEDicine in Spain (WOMEDS) project ( https://womeds.es ) aims to describe and characterize, in a systematic and detailed way, the gender bias in the medical profession in Spain in order to monitor its evolution over time and contribute to prioritizing gender policies. METHODS: We retrieved data for the calendar years 2019-2021 from several sources and selected surveys. We built four groups of indicators to describe leadership positions in the medical profession: (i) leadership in healthcare according to specialty and region; (ii) leadership in scientific and professional bodies; (iii) academic career; and (iv) leadership in clinical research activity. As a summary measure, we reported the women ratios, calculated as the percentage of women in specific top positions divided by the percentage of women in the relevant population. RESULTS: We found gender inequity in leadership positions in all four settings. During the observed period, only 27.6% of the heads of departments in hospitals were women compared to 61.1% of women in medical staff. Ten of the 46 medical societies grouped in the Spanish Federation of Medical Societies (FACME) (21.7%) had a women president at some point during the study period, and only 4 annual congresses had ratios of women speakers higher than 1. Women were over-represented in the lower positions and underrepresented in the top academic ones. Only 26% and 27%, respectively, of the heads of departments and deans were women. The applications for public funding for research projects are led by women only in 45% of the cases, and the budget granted to women in public calls was 24.3% lower than that of men. CONCLUSION: In all the areas analyzed, the leadership positions are still mostly occupied by men despite the feminization of medicine in Spain. The severe gender inequity found calls for urgent interventions within a defined time horizon. Such measures must concern all levels, from national or regional regulation to changes in organizational culture or incentives in specific organizations.


RESUMEN EN ESPAÑOL: ANTECEDENTES: La prolongada infrarrepresentación de las mujeres en los puestos de liderazgo en medicina es bien conocida, pero está poco documentada de forma global. Hay evidencia sobre la brecha de género en la universidad, en el liderazgo en sociedades médicas o en determinadas especialidades. Sin embargo, no hay investigaciones que analicen el techo de cristal de cada una de las especialidades médicas desde una perspectiva 360º que incluya el liderazgo en la universidad, en la investigación con fondos públicos, en la representación en sociedades científicas y colegios profesionales y en la actividad clínica. Además, la mayoría de los estudios tienen una perspectiva estadounidense y nos preguntamos si la perspectiva de un país europeo podría ser diferente. El proyecto Mujeres en Medicina en España (WOMEDS) ( https://womeds.es ) tiene como objetivo describir y caracterizar de forma sistemática y detallada sesgo de género en la profesión médica en España, para monitorizar su evolución en el tiempo y contribuir a priorizar las políticas de género. MéTODOS: Construimos cuatro grupos de indicadores sobre liderazgo de mujeres médicos: (i) en la asistencia sanitaria; (ii) en las organizaciones científicas y profesionales; (iii) carrera académica, y; and (iv) l en la investigación basándonos en datos públicos y resultados de encuestas propias s referidas a los años 2019­2021. Como medida de análisis, calculamos los ratios de mujeres, definidos como el porcentaje de mujeres en puestos altos específicos dividido por el porcentaje de mujeres en la población relevante. RESULTADOS: Encontramos un sesgo de género en los cuatro ámbitos. Durante el periodo observado, solo el 27.6% de los jefes de servicio de los hospitales eran mujeres, frente al 61.1% de mujeres en la plantilla. Diez de las 46 sociedades médicas agrupadas en la Federación de Asociaciones Científico Médicas Españolas (FACME) (21.7%) tuvieron una mujer como presidente en algún momento del periodo de estudio y sólo 4 congresos anuales tenían ratios de mujeres ponentes superiores a 1. Las mujeres estaban sobrerepresentadas en los cargos inferiores e infrarrepresentadas en los cargos académicos superiores. Sólo el 26% y el 27%, respectivamente, de los jefes de departamento y decanos eran mujeres. La solicitud de proyectos de investigación con financiación pública fue liderada por mujeres en un 45% de los casos y la financiación media de los proyectos concedidos a las mujeres fue un 24.3% inferior a la de los hombres. CONCLUSIóN: En todos los ámbitos analizados, las posiciones de liderazgo siguen siendo mayoritariamente ocupada por varones a pesar de la feminización de la medicina. Para cambiar esto, será necesario tomar medidas, tanto regulatorias -a nivel nacional y nacional regional como promover cambios en la cultura organizativa o en los incentivos en organizaciones concretas.

RESUMO

Obesity has become a major epidemic in the 21st century. It increases the risk of dyslipidemia, hypertension, and type 2 diabetes, which are known cardiometabolic risk factors and components of the metabolic syndrome. Although overt cardiovascular (CV) diseases such as stroke or myocardial infarction are the domain of adulthood, it is evident that the CV continuum begins very early in life. Recognition of risk factors and early stages of CV damage, at a time when these processes are still reversible, and the development of prevention strategies are major pillars in reducing CV morbidity and mortality in the general population. In this review, we will discuss the role of well-known but also novel risk factors linking obesity and increased CV risk from prenatal age to adulthood, including the role of perinatal factors, diet, nutrigenomics, and nutri-epigenetics, hyperuricemia, dyslipidemia, hypertension, and cardiorespiratory fitness. The importance of 'tracking' of these risk factors on adult CV health is highlighted and the economic impact of childhood obesity as well as preventive strategies are discussed.

RESUMO

OBJECTIVE: This study was aimed at evaluating the appropriateness of use and interpretation of rapid antigen detection testing (RADT) and antibiotic prescribing for acute pharyngitis six years after a multifaceted intervention. DESIGN: Before-and-after audit-based study. LOCATION: Primary care centres in eight autonomous Communities. PARTICIPANTS: General practitioners (GP) who had participated in the HAPPY AUDIT intervention study in 2008 and 2009 were invited to participate in a third audit-based study six years later (2015). METHOD: RADTs were provided to the participating practices and the GPs were requested to consecutively register all adults with acute pharyngitis. A registration form specifically designed for this study was used. RESULTS: A total of 121 GPs out of the 210 who participated in the first two audits agreed to participate in the third audit (57.6%). They registered 3394 episodes of pharyngitis in the three registrations. RADTs were used in 51.7% of all the cases immediately after the intervention, and in 49.4% six years later. Antibiotics were prescribed in 21.3% and 36.1%, respectively (P<.001), mainly when tonsillar exudates were present, and in 5.3% and 19.2% of those with negative RADT results (P<.001). On adjustment for covariables, compared to the antibiotic prescription observed just after the intervention, significantly more antibiotics were prescribed six years later (odds ratio: 2.24, 95% confidence interval: 1.73-2.89). CONCLUSIONS: This study shows that that the long-term impact of a multifaceted intervention, focusing on the use and interpretation of RADT in patients with acute pharyngitis, is reducing.

RESUMO

INTRODUCTION: General practitioners (GP) in Spain do not have access to rapid tests and adherence to guidelines is usually suboptimal. The aim of the study is to evaluate the estimated number of antibiotics that could have been saved if GPs had appropriately used these tests and had followed the guidelines. DESIGN: Observational study. SETTING: Primary care centres from eight Autonomous Communities in Spain. PARTICIPANTS: GPs who had not participated in previous studies on rational use of antibiotics. INTERVENTION: GPs registered all the cases of pharyngitis and lower respiratory tract infections (LRTI) during 15 working days in 2015, by means of a 47-item audit. MAIN MEASUREMENTS: Actual GPs' antibiotic prescription and estimated number of antibiotics that could have been saved according to recent guidelines. RESULTS: A total of 126 GPs registered 1012 episodes of pharyngitis and 1928 LRTIs. Antibiotics were given or patients were referred in 497 patients with pharyngitis (49.1%) and 963 patients with LRTI (49.9%). If GPs had appropriately used rapid antigen detection tests and C-reactive protein tests and had strictly followed current guidelines, antibiotics would have been given to 7.6% and 15.1%, respectively, with an estimated saving of 420 antibiotics in patients with sore throat (estimated saving of 84.5%; 95% CI: 81.1-87.4%) and 672 antibiotics in LRTIs (estimated saving of 69.8%,95% CI: 67.1-72.5%). CONCLUSIONS: GP adherence to guidelines and a correct introduction of rapid tests in clinical practice in Spain could result in a considerable saving of unnecessary prescription of antibiotics in pharyngitis and LRTIs.

RESUMO

This paper provides empirical evidence on the explanatory factors affecting introductory prices of new pharmaceuticals in a heavily regulated and highly subsidized market. We collect a data set consisting of all new chemical entities launched in Spain between 1997 and 2005, and model launch prices following an extended version of previous economic models. We found that, unlike in the US and Sweden, therapeutically "innovative" products are not overpriced relative to "imitative" ones after having controlled for other factors. Price setting is mainly used as a mechanism to adjust for inflation independently of the degree of innovation. The drugs that enter through the centralized EMA approval procedure are overpriced, which may be a consequence of market globalization and international price setting.

RESUMO

BACKGROUND: Excessive use of antibiotics is worldwide the most important reason for development of antimicrobial resistance. As antibiotic resistance may spread across borders, high prevalence countries may serve as a source of bacterial resistance for countries with a low prevalence. Therefore, bacterial resistance is an important issue with a potential serious impact on all countries. Initiatives have been taken to improve the quality of antibiotic prescribing in primary care, but only few studies have been designed to determine the effectiveness of multifaceted strategies across countries with different practice setting. The aim of this study was to evaluate the impact of a multifaceted intervention targeting general practitioners (GPs) and patients in six countries with different health organization and different prevalence of antibiotic resistance. METHODS: GPs from two Nordic countries, two Baltic Countries and two Hispano-American countries registered patients with respiratory tract infections (RTIs) in 2008 and 2009. After first registration they received individual prescriber feedback and they were offered an intervention programme that included training courses, clinical guidelines, posters for waiting rooms, patient brochures and access to point of care tests (Strep A and C-Reactive Protein). Antibiotic prescribing rates were compared before and after the intervention. RESULTS: A total of 440 GPs registered 47011 consultations; 24436 before the intervention (2008) and 22575 after the intervention (2009). After the intervention, the GPs significantly reduced the percentage of consultations resulting in an antibiotic prescription. In patients with lower RTI the GPs in Lithuania reduced the prescribing rate by 42%, in Russia by 25%, in Spain by 25%, and in Argentina by 9%. In patients with upper RTIs, the corresponding reductions in the antibiotic prescribing rates were in Lithania 20%, in Russia 15%, in Spain 9%, and in Argentina 5%. CONCLUSION: A multifaceted intervention programme targeting GPs and patients and focusing on improving diagnostic procedures in patients with RTIs may lead to a marked reduction in antibiotic prescribing. The pragmatic before-after design used may suffer from some limitations and the reduction in antibiotic prescribing could be influenced by factors not related to the intervention.

RESUMO

BACKGROUND: Spain has gone from a surplus to a shortage of medical doctors in very few years. Medium and long-term planning for health professionals has become a high priority for health authorities. METHODS: We created a supply and demand/need simulation model for 43 medical specialties using system dynamics. The model includes demographic, education and labour market variables. Several scenarios were defined. Variables controllable by health planners can be set as parameters to simulate different scenarios. The model calculates the supply and the deficit or surplus. Experts set the ratio of specialists needed per 1000 inhabitants with a Delphi method. RESULTS: In the scenario of the baseline model with moderate population growth, the deficit of medical specialists will grow from 2% at present (2800 specialists) to 14.3% in 2025 (almost 21 000). The specialties with the greatest medium-term shortages are Anesthesiology, Orthopedic and Traumatic Surgery, Pediatric Surgery, Plastic Aesthetic and Reparatory Surgery, Family and Community Medicine, Pediatrics, Radiology, and Urology. CONCLUSIONS: The model suggests the need to increase the number of students admitted to medical school. Training itineraries should be redesigned to facilitate mobility among specialties. In the meantime, the need to make more flexible the supply in the short term is being filled by the immigration of physicians from new members of the European Union and from Latin America.

RESUMO

The present financial crisis will affect primary cancer prevention through several avenues: personal lifestyle choices, exposure to environmental risk factors, decisions made in the private sector and public policy on cancer prevention. Whilst it is clearly problematic to reach solid conclusions on a direct connection between economic crises and cancer mortality, we can identify trends that provide guidance for further action. For some lifestyle choices such as smoking or diet, we argue that public policy may channel existing tendencies during times of crisis for clear added value. In other areas, including research and health system investments, we will make the case that the resources not used now for cancer prevention efforts will lead to increased costs (both financial and human) down the road. Policy makers face a clear choice: they can follow a cost contention strategy, which may reduce expenditure in the short-term only to increase it in the long-term, or they can use the financial crisis as an opportunity to make difficult choices in terms of health service rationalisation, whilst at the same time strengthening evidence-based prevention policies. In short, we argue that despite the scarcity of funds and the governmental priorities on economic recovery, cancer prevention is more relevant now than ever.

RESUMO

'Welfare' is a vague term, the meaning of which depends on ideology, values and judgements. Material resources are just means to enhance people's well-being, but growth of Gross Domestic Product is still the standard measure of a society's success. Fortunately, recent advances in measuring social performance include health, education and other social outcomes. Because 'what we measure affects what we do', it is hoped that social policies will change, and that a contribution will be made by Health in All Policies and associated health impact assessment methodology. The task consists of designing transversal policies that consider health and other welfare goals, the short-term and long-term implications and intergenerational redistributions of resources. Cross-sectoral policies are required for efficiency and fairness. Unless inefficiencies in current healthcare systems are reduced, welfare states will fail to consolidate and overall economic well-being could be in serious trouble. In this essay, some policy solutions are sketched. An independent agency, the National Institute for Welfare Enhancement, is proposed for long-term fair and efficient social policies in which health plays a central role.

RESUMO

BACKGROUND: Excessive and inappropriate use of antibiotics is considered to be the most important reason for development of bacterial resistance to antibiotics. As antibiotic resistance may spread across borders, high prevalence countries may serve as a source of bacterial resistance for countries with a low prevalence. Therefore, bacterial resistance is an important issue with a potential serious impact on all countries. The majority of respiratory tract infections (RTIs) are treated in general practice. Most infections are caused by virus and antibiotics are therefore unlikely to have any clinical benefit. Several intervention initiatives have been taken to reduce the inappropriate use of antibiotics in primary health care, but the effectiveness of these interventions is only modest. Only few studies have been designed to determine the effectiveness of multifaceted strategies in countries with different practice setting. The aim of this study is to evaluate the impact of a multifaceted intervention targeting general practitioners (GPs) and patients in six countries with different prevalence of antibiotic resistance: Two Nordic countries (Denmark and Sweden), two Baltic Countries (Lithuania and Kaliningrad-Russia) and two Hispano-American countries (Spain and Argentina). METHODS/DESIGN: HAPPY AUDIT was initiated in 2008 and the project is still ongoing. The project includes 15 partners from 9 countries. GPs participating in HAPPY AUDIT will be audited by the Audit Project Odense (APO) method. The APO method will be used at a multinational level involving GPs from six countries with different cultural background and different organisation of primary health care. Research on the effect of the intervention will be performed by analysing audit registrations carried out before and after the intervention. The intervention includes training courses on management of RTIs, dissemination of clinical guidelines with recommendations for diagnosis and treatment, posters for the waiting room, brochures to patients and implementation of point of care tests (Strep A and CRP) to be used in the GPs'surgeries. To ensure public awareness of the risk of resistant bacteria, media campaigns targeting both professionals and the public will be developed and the results will be published and widely disseminated at a Working Conference hosted by the World Association of Family Doctors (WONCA-Europe) at the end of the project period. DISCUSSION: HAPPY AUDIT is an EU-financed project with the aim of contributing to the battle against antibiotic resistance through quality improvement of GPs' diagnosis and treatment of RTIs through development of intervention programmes targeting GPs, parents of young children and healthy adults. It is hypothesized that the use of multifaceted strategies combining active intervention by GPs will be effective in reducing prescribing of unnecessary antibiotics for RTIs and improving the use of appropriate antibiotics in suspected bacterial infections.

RESUMO

BACKGROUND: Studies conducted to obtain drug authorization are often of short duration and based on small sample sizes in selected populations. Policies on drug safety rely on the validity of the methods used to achieve rapid and effective communication of new information. No formal evaluation has ever been made of the Spanish communications system, although indirect data have raised questions about its effectiveness. OBJECTIVE: To evaluate the impact of two safety warnings issued by the Spanish Drug Agency, and of a later prior authorization requirement involving the use of atypical antipsychotic drugs in the elderly. METHODS: The study was based on a time-series analysis constructed with data corresponding to monthly invoicing from 2000 to 2006 for olanzapine and risperidone in the Region of Valencia, Spain. Because the safety warnings and the prior authorization policy applied exclusively to prescriptions of these drugs for elderly patients with dementia, we investigated whether these interventions were successful and therefore changed prescription patterns for pensioners receiving low-strength formulations (the available proxy for elderly subjects with dementia), without altering patterns for those receiving the highest-strength formulations (typically used in schizophrenic patients) or for prescriptions for non-pensioners (any strength formulations). These two latter groups were therefore established as the control groups. RESULTS: Defined daily doses (DDDs) for olanzapine in low-strength pharmaceutical forms showed a clear levelling off after the first warning, while that for risperidone showed less pronounced decline. The prior authorization policy had a dramatic effect on the consumption of risperidone, but not on that of olanzapine. DDDs for low-strength formulations between the 12 months prior to the first warning and the 12 months following the prior authorization showed a substantial reduction (22% for risperidone and 33% for olanzapine). In the high-strength forms and in non-pensioners the upward trends in DDDs remained unaltered after both interventions. CONCLUSION: The safety warnings concerning atypical antipsychotic drugs were effective in reducing the prescribing of risperidone and olanzapine in low-strength doses in pensioner prescriptions, and the implementation of a prior authorization policy had a dramatic effect on the prescribing of risperidone.

RESUMO

BACKGROUND: The importance of Small Area Variation Analysis for policy-making contrasts with the scarcity of work on the validity of the statistics used in these studies. Our study aims at 1) determining whether variation in utilization rates between health areas is higher than would be expected by chance, 2) estimating the statistical power of the variation statistics; and 3) evaluating the ability of different statistics to compare the variability among different procedures regardless of their rates. METHODS: Parametric bootstrap techniques were used to derive the empirical distribution for each statistic under the hypothesis of homogeneity across areas. Non-parametric procedures were used to analyze the empirical distribution for the observed statistics and compare the results in six situations (low/medium/high utilization rates and low/high variability). A small scale simulation study was conducted to assess the capacity of each statistic to discriminate between different scenarios with different degrees of variation. RESULTS: Bootstrap techniques proved to be good at quantifying the difference between the null hypothesis and the variation observed in each situation, and to construct reliable tests and confidence intervals for each of the variation statistics analyzed. Although the good performance of Systematic Component of Variation (SCV), Empirical Bayes (EB) statistic shows better behaviour under the null hypothesis, it is able to detect variability if present, it is not influenced by the procedure rate and it is best able to discriminate between different degrees of heterogeneity. CONCLUSION: The EB statistics seems to be a good alternative to more conventional statistics used in small-area variation analysis in health service research because of its robustness.

RESUMO

This paper contributes to the empirical knowledge of determinants of smoking initiation in adolescents. The instrument we used was a structural equation model, which is a powerful tool to analyze causal relationships in nonexperimental studies. We used a school-based sample of 1198 teenagers from Spain. We measured the attitude of the adolescents towards tobacco. Attitudes and smoking status are related. Attitudes become more favorable to smoking, as experimentation with cigarettes progresses and pupils become older. Teenagers who have tried at least one cigarette are on average more favorable to smoking than those who had never smoked. The study's limitations were noted.
