["We are families too": LGBT experiences and demands for access to Surrogacy in Argentina]. / "También somos familias": experiencias y demandas LGBT por el acceso a la gestación por sustitución en Argentina.

Surrogacy (GS) has been established as a means of access to male homoparenting and, despite not being regulated in Argentina, it is negotiated in a "paralegal" scenario. For some time now, LGBT organizations have proposed regulation based on the argument that GS represents the only option available for a male homosexual couple to have a child with a genetic link, albeit with only one of them, and consecutively acknowledge the family ties of both. By means of ethnographic work carried out within the scope of a postgraduate research project, our objective is to ascertain the experiences of male homosexual couples who seek the legitimacy of GS processes and equal access to the healthcare system. With this in mind, we seek a reflection that articulates the construction of public health policies and the claims of sectors of the LGBT movement, focusing on the meanings of the collective experience, on the ways in which these actors organize their family demands, and on the conceptions and practices that articulate these claims with the production of public policies.

La gestación por sustitución (GS) se ha instalado como una vía de acceso a la homoparentalidad masculina y pese a que en Argentina no está reglamentada, se lleva adelante en un escenario "paralegal". Desde hace tiempo, organizaciones LGBT proponen su regulación bajo el argumento de que la GS representa la única opción que tiene una pareja de varones homosexuales de tener un/a hijo/a con lazo genético, aunque sólo con uno de ellos, y reconocer consecutivamente ambos vínculos filiatorios. A través del trabajo etnográfico realizado en el marco de un proyecto de investigación de posgrado, nuestro objetivo es recuperar las experiencias de parejas gays que buscan la legitimidad de los procesos de GS y el acceso igualitario en el sistema de salud. En ello, apuntamos a una reflexión que articula la construcción de políticas públicas en salud y los reclamos de sectores del movimiento LGBT, poniendo el foco en los sentidos de la experiencia colectiva, en los modos en que estos actores organizan sus demandas familiaristas y en las concepciones y prácticas que articulan esos reclamos con la producción de políticas públicas.

Global relevance of Argentinean rainfed crops in a climatic variability context: A water footprint assessment in Buenos Aires province.

Argentina has a relevant international role as a producer of agricultural commodities. Buenos Aires is the province with the largest cultivated area of cereals and oilseeds of the country. Rainfed crops depend exclusively on green water, meaning a comparative advantage for Buenos Aires province. The green virtual water content in the crops produced in Buenos Aires has implications for water allocation at international level. A great amount of countries depends on the Argentinean rainfed agriculture. Therefore, it is important to understand the effects of climate variations on Argentinean crop production at local level and the role of rainfed crops in regional and international trade. We analysed the temporal and territorial variations of crops green water demand in a climatic variability context and their influence on the water footprint. The green water footprint of the main crops of Buenos Aires was assessed, including soybeans, maize, sunflower, wheat and barley, in different climatic conditions: for the period 2008-2018, which include a dry year, a humid year and an ordinary year. A dataset about the green water footprint at municipality level was provided, and the results were presented on maps for each crop and for the different climatic conditions. The relevance of green water of main crops in the world water-dependent supply chains was shown. This comprehensive green water footprint assessment provides a useful database for researchers, companies and policy makers in Argentina and beyond.

Assessment of the mechanical and physical characteristics of PET bricks with different aggregates.

Construction and demolition waste, along with discarded PET plastic bottles, have evolved into a widespread global resource. However, their current disposal in landfills poses a significant environmental pollution challenge. This research is centered on evaluating the performance of cement mortar composed by larger PET particles in conjunction with sand, construction and demolition waste, and lightweight expanded polystyrene aggregates. The primary objective of this study is to formulate a blend suitable for non-structural elements that can be easily manufactured for social housing construction. This modified blend extends upon the original certified mixture employed at CEVE for brick production, which encompasses cement and 3 mm-long PET particles. The experimental analysis revealed that blend containing 8 mm-long PET particles, in combination with fine aggregates of construction and demolition waste, attained a required mechanical strength of 2 MPa, while preserving the bulk density and hydric properties of the initial PET bricks developed at CEVE in Argentina.

A Cross-National Comparison of Biosimilars Pricing in Argentina, Australia, Brazil, and Italy.

BACKGROUND: Biosimilar medicines are defined as biological products highly similar to an already licensed biological product (RP). The market entry of biosimilars is expected to reduce the costs of biological treatments. OBJECTIVE: This study aims to evaluate the range of differences between the prices of biosimilars and the corresponding RP for biologicals approved in four countries. METHOD: This is a cross-national comparison of pricing of biosimilars in Argentina, Australia, Brazil, and Italy. The study examined online price databases provided by the national authorities of the investigated countries. Biosimilar price difference was calculated by subtracting the unit price of the biosimilar by the unit price of the RP, and then dividing it by the unit price of the RP. The results were presented as percentage. RESULTS: Brazil had the highest median price reduction (- 36.3%) in biosimilars price, followed by Italy (- 20.0%) and Argentina (- 18.6%). All the biosimilars in Italy were priced below the RP presenting a minimum reduction of 6.3%, while in Australia, most of the prices of biosimilars were equal to the RP. In Argentina, one infliximab-biosimilar displayed price above the RP (40.7%) while the lower priced brand had a reduction of 14.4%. Brazil had four biosimilars with prices above the respective RP, including isophane insulin (1), insulin glargine (1) and somatropin (2). CONCLUSION: The study revealed a marked dispersion in the price's differences between biosimilars and RP across the studied countries. Governments should evaluate whether their policies have been successful in improving affordability of biological therapies.

Assessment of Mayaro virus vector competence of the mosquito Aedes aegypti (Linnaeus, 1762) populations in Argentine using dose-response assays.

Mayaro virus (MAYV; Alphavirus: Togaviridae) is an emerging pathogen in Latin America, causing fever and polyarthritis. Sporadic outbreaks of MAYV have occurred in the region, with reported human cases being imported to Europe and North America. Although primarily a risk for those residing in the Amazon basin's tropical forests, recent reports highlight that urbanization would increase the risk of MAYV transmission in Latin America. Urban emergence depends on human susceptibility and the ability of mosquitos like Aedes aegypti  (Linnaeus, 1762) (Diptera: Culicidae) to transmit MAYV. Despite the absence of active MAYV transmission in Argentine, the risk of introduction is substantial due to human movement and the presence of Ae. aegypti in the region. This study aimed to evaluate the susceptibility of different Argentine Ae. aegypti populations to MAYV genotype L (MAYV-L) using dose-response assays and determine barriers to virus infection, dissemination and transmission. Immature mosquito stages were collected in Buenos Aires, Córdoba and Rosario cities. Female Ae. aegypti (F2) were orally infected by feeding on five concentrations of MAYV-L, ranging from 1.0 to 6.0 log10 PFU/mL. Abdomens, legs and saliva were analysed using viral plaque assays. Results revealed that MAYV-L between infection and dissemination were associated with viral doses rather than the population origin. Infection rates varied between 3% and 65%, with a 50% infectious dose >5.5 log10 PFU/mL. Dissemination occurred at 39%, with a 50% dissemination dose of ~6.0 log10 PFU/mL. Dissemination among infected mosquitoes ranged from 60% to 86%, and transmission from disseminated mosquitoes ranged from 11% to 20%. Argentine Ae. aegypti populations exhibited a need for higher viral doses of MAYV-L than those typically found in humans to become infected. In addition, only a small proportion of infected mosquitoes were capable of transmitting the virus. Understanding MAYV transmission in urban areas is crucial for public health interventions.

Income, stress, and sex ratios over 1895-2010.

The medical literature has shown that populations under high stress have a lower sex ratio at birth (i.e. number of males for every 100 females). In this paper, I examine the relationship between income, as a source of economic stress, and the sex ratio at a subnational level for the 1895-2010 period. For this, I use census microdata from Argentina -a developing country that experienced rapid growth at the end of the 19th century and stagnated in recent decades- and I estimate from a two-way fixed effects model that exploits the wide temporal and geographic variability in income. The results show that as per capita income increases, the sex ratio at birth also increases. In particular, for every US$ 1,000 increase in per capita income, the sex ratio increases between 0.3 and 0.6 points. These findings make it possible to quantify the lost boys (i.e. those boys who were not born due to high economic stress on their parents) and constitute a call for attention in favor of the implementation of prenatal care policies -especially in periods of stagnation or income decline- to maintain a more balanced sex ratio.

Introduction. The assessment of physical fitness (PF), is useful strategy to know the current status of schoolchildren. Our primary objective was to measure the current health status and PF levels of schoolchildren in San Luis and to develop PF reference tables. Population and methods. Schoolchildren aged 9 to 12 years (boys and girls) were assessed based on 2 health indicators: body mass index and blood pressure. PF was measured using the ALPHA-Fitness test battery. Blood pressure, body mass, height, foot and hand length, standing long jump, 30 m sprint, 4 × 10 m agility test, and 20 m shuttle run test were assessed. The body mass index (BMI) and biological maturation were estimated. Results. A total of 15 548 schoolchildren were assessed. Average systolic blood pressure was 101 ± 10 mmHg and diastolic blood pressure, 66 ± 7 mmHg; BMI: 20.2 ± 4.3 kg/m2. Average PF was, in the cardiorespiratory component, VO2 max.: 39.87 ± 3.2 mL/kg/min and speed reached during the 20 m shuttle run test: 8.9 ± 0.6 km/h; in the musculoskeletal component, standing long jump: 120.6 ± 23.9 cm, 30 m sprint: 6.56 ± 0.85 s, 4 × 10 m agility test: 15.17 ± 1.82 s. The performance was better in the boys group (p < 0.001). Conclusion. Blood pressure was normal. Fifty percent of the sample was overweight or obese as per their BMI. Both boys and girls showed low PF levels. PF reference tables for schoolchildren from San Luis were developed for the first time.

Cost of illness due to respiratory syncytial virus acute lower respiratory tract infection among infants hospitalized in Argentina.

BACKGROUND: Information is scarce regarding the economic burden of respiratory syncytial virus (RSV) disease in low-resource settings. This study aimed to estimate the cost per episode of hospital admissions due to RSV severe disease in Argentina. METHODS: This is a prospective cohort study that collected information regarding 256 infants under 12 months of age with acute lower respiratory tract infection (ALRTI) due to RSV in two public hospitals of Buenos Aires between 2014 and 2016. Information on healthcare resource use was collected from the patient's report and its associated costs were estimated based on the financial database and account records of the hospitals. We estimated the total cost per hospitalization due to RSV using the health system perspective. The costs were estimated in US dollars as of December 2022 (1 US dollar = 170 Argentine pesos). RESULTS: The mean costs per RSV hospitalization in infants was US$587.79 (95% confidence interval [CI] $535.24 - $640.33). The mean costs associated with pediatric intensive care unit (PICU) admission more than doubled from those at regular pediatric wards ($1,556.81 [95% CI $512.21 - $2,601.40] versus $556.53 [95% CI $514.59 - $598.48]). CONCLUSIONS: This study shows the direct economic impact of acute severe RSV infection on the public health system in Argentina. The estimates obtained from this study could be used to inform cost-effectiveness analyses of new preventive RSV interventions being developed.

Off-premises demand elasticities for pure alcohol in five Latin American countries: The case of Argentina, Chile, Costa Rica, Honduras, and Uruguay.

BACKGROUND AND AIMS: There is ample evidence from high-income countries that fiscal policies such as alcohol taxes can affect the consumption of alcohol by increasing alcohol prices. In the case of Latin American countries, much less is known about how sensitive alcohol demand is to alcohol price changes. This study aims to expand the evidence base on the sensitivity of off-premises pure alcohol demand to price and expenditure increases in five Latin American countries: Argentina, Chile, Costa Rica, Honduras, and Uruguay, which have different socioeconomic profiles and alcohol consumption patterns. DESIGN AND SETTING: Cross-sectional study MEASUREMENTS: The price and expenditure elasticities were estimated using an Almost Ideal Demand System (AIDS). Own price and expenditure elasticities for off-premises pure alcohol were estimated using representative household surveys, which collect data on households' expenses to construct the consumer basket of goods and services used to calculate the consumer price index (CPI) for the country. FINDINGS: Own price elasticities of off-premises pure alcohol for all countries were negative, inelastic, and significant at 1 %. They were -0.418 for Argentina; -0.656 for Chile; and for Costa Rica, Honduras, and Uruguay, they were equal to -0.608, -0.509, and -0.32, respectively. Expenditure elasticities were positive and significant at 1 %, except for Costa Rica, which was significant at 10 %. They were equal to 0.865 in Argentina; 0.943 in Chile; 1.182 in Costa Rica; 0.874 in Honduras; and 0.857 in Uruguay. Elasticities for Costa Rica should be interpreted cautiously, as there is insufficient geographical price variability to identify the demand correctly. CONCLUSIONS: Results were consistent with previous literature for countries from other regions. Governments should expand this study to measure total demand elasticities to improve the design of alcohol tax policies.

Impact of Lung Cancer on Health-Related Quality of Life, Financial Toxicity, and Household Economics in Patients From the Public and the Private Healthcare Sector in Argentina.

OBJECTIVES: Non-small cell lung cancer (NSCLC) is Argentina's first cause of cancer death. Most patients have an advanced stage at diagnosis, with poor expected survival. This study aimed to characterize the health-related quality of life (HRQOL) and economic impact of patients treated in the private healthcare sector and compare it with that of the public sector. METHODS: We undertook an observational cross-sectional study that extended a previous study to a referral private center in Argentina. Outcomes included the EuroQol EQ-5D-3L (to assess HRQOL), Comprehensive Score for Financial Toxicity (financial toxicity instrument), Work Productivity and Activity Impairment - General Health (to assess productivity loss), and out-of-pocket expenses in adults diagnosed of NSCLC. RESULTS: We included 30 consecutive patients from a private healthcare center (July 2021 to March 2022), totaling 131 patients (n = 101 from previous public study). The whole sample had low quality of life and relevant economic impact. Patients in the private healthcare sector showed lower disease severity and higher educational level and household income. In addition, private healthcare system patients showed higher utility (0.77 vs 0.73; P < .05) and lower impairment of daily activities (41% vs 59%; P = .01). Private health system patients also showed lower financial toxicity as measured by the Comprehensive Score for Financial Toxicity score (23.9 vs 20.14; P < .05) but showed no differences when financial toxicity was assessed as a dichotomic variable. CONCLUSIONS: Although patients with NSCLC treated in a private healthcare center in Argentina showed a relevant HRQOL and economic impact, this impact was smaller than the one observed in publicly funded hospitals.

Budget impact analysis of venetoclax for the management of acute myeloid leukemia from the perspective of the social security and the private sector in Argentina.

OBJECTIVE: This study aimed to estimate the budget impact of the incorporation of venetoclax for the treatment of patients with Acute Myeloid Leukemia (AML) over 75 years of age or those with comorbidities and contraindications for the use of intensive chemotherapy, from the perspective of the social security and the private third-party payers in Argentina. METHODS: A budget impact model was adapted to estimate the cost difference between the current scenario (azacitidine, decitabine and low doses of cytarabine) and the new scenario (incorporation of venetoclax) for a third-party payer over a time horizon of three years. Input parameters were obtained from a literature review, validated or complemented by expert opinion using a modified Panel Delphi approach. All direct medical costs were estimated by the micro-costing approach and were expressed in US dollars (USD) as of September 2020 (1 USD = 76.18 Argentine pesos). RESULTS: For a third-party payer with a cohort of 1,000,000 individuals covered, incorporating venetoclax was associated with an average budget impact per-member per-month (PMPM) of $0.11 USD for the social security sector and $0.07 USD for the private sector. The duration of treatment with venetoclax was the most influential parameter in the budget impact results. CONCLUSION: The introduction of venetoclax was associated with a positive and slight budget impact. These findings are informative to support policy decisions aimed to expand the current treatment landscape of AML.

[Geographic variability, health inequities and lethality due to COVID-19 in Bariloche, Río Negro, 2020-2021]. / Variabilidad geográfica, inequidades en salud y letalidad por COVID-19 en Bariloche, Río Negro, 2020-2021.

INTRODUCTION: The objective of this study was to analyze the geographic variability and the relationship between social determinants of health and COVID-19 lethality in Bariloche. METHODS: A database from the National Epidemiological Surveillance System was used to analyze COVID-19 positive cases from January 2020 to December 2021. The data were geocoded and incorporated into a geographic information system (GIS). A three-step analytical framework was applied to measure health inequity, using socioeconomic indicators and access to services. A multivariate analysis was conducted to predict fatality. RESULTS: A total of 25 020 COVID-19 cases were diagnosed in Bariloche during the study period. The fatality rate was 2.1%. Significant variability in socioeconomic indicators was observed among different territorial delegations of the city. DISCUSSION: The results showed health inequities and an association between social determinants and COVID-19 lethality in Bariloche. Individuals living in areas with higher socioeconomic vulnerability had a higher risk of mortality. These findings highlight the importance of addressing health inequities in a pandemic response.

Introducción: El objetivo de este estudio fue examinar cómo la variabilidad geográfica y los determinantes sociales de la salud influyen en la tasa de letalidad por COVID-19 en Bariloche. Métodos: Se utilizó una base de datos del Sistema Nacional de Vigilancia Epidemiológica para analizar los casos positivos de COVID-19 desde enero de 2020 hasta diciembre de 2021. Los datos se geo-codificaron y se incorporaron en un sistema de información geográfica (SIG). Se aplicó un marco de análisis en tres pasos para medir la inequidad en salud, utilizando indicadores socioeconómicos y de acceso a servicios. Se realizó un análisis multivariado para predecir la letalidad. Resultados: Se diagnosticaron un total de 25 020 casos de COVID-19 en Bariloche durante el período de estudio. La letalidad fue del 2.1%. Se observó una variabilidad significativa en indicadores socioeconómicos entre las diferentes delegaciones territoriales de la ciudad. Discusión: Los resultados mostraron inequidades en salud y una asociación entre determinantes sociales y letalidad por COVID-19 en Bariloche. Las personas que vivían en áreas con mayor vulnerabilidad socioeconómica presentaron un mayor riesgo de mortalidad. Estos hallazgos resaltan la importancia de abordar las inequidades en salud en la respuesta a una pandemia.

Integrated water quality assessment of two Rivers Basins from a semiarid region of Argentina.

The Tunuyán and Mendoza River Basins (Province of Mendoza, Argentina) have been selected as a representative semiarid region to test the applicability of an integrated water quality evaluation. To detect spatio-temporal variations of anthropic contamination, physicochemical and bacteriological parameters, as well as three ecotoxicological assays, were assessed in reference sites for 3 years. Bioassays based on the nematode Caenorhabditis elegans, the vascular plant Lactuca sativa, and the algae Pseudokirchneriella subcapitata were performed and toxicological categories were established. Our results showed that water quality, as well as water toxicity, deteriorates as both river systems run through urban areas. Interestingly, monitoring sites with good physicochemical and bacteriological qualities but with toxicity were identified, illustrating that traditional water quality studies do not predict potential toxic effects on living organisms. In addition, a multivariate statistical analysis was performed to detect clusters of monitoring sites according to the water quality status. In the context of climate change, this study provides information to support that integrated water monitoring is an essential tool to ensure sustainable water management and to guarantee economic growth, human health, food security, and environmental protection.

Endoscopic scoring system utilization for inflammatory bowel disease activity assessment: A multicenter real-world study from Argentina.

BACKGROUND: The frequency and patterns of use of scores for the assessment of endoscopic activity in inflammatory bowel disease patients are not known. AIM: To describe the prevalence of adequate use of endoscopic scores in IBD patients who underwent colonoscopy in a real-life setting. MATERIALS AND METHODS: A multicenter observational study comprising six community hospitals in Argentina was undertaken. Patients with a diagnosis of Crohn's disease or ulcerative colitis who underwent colonoscopy for endoscopic activity assessment between 2018 and 2022 were included. Colonoscopy reports of included subjects were manually reviewed to determine the proportion of colonoscopies that included an endoscopic score report. We determined the proportion of colonoscopy reports that included all of the IBD colonoscopy report quality elements proposed by BRIDGe group. Endoscopist's specialty, years of experience as well as expertise in IBD were assessed. RESULTS: A total of 1556 patients were included for analysis (31.94% patients with Crohn's disease). Mean age was 45.94±15.46. Endoscopic score reporting was found in 58.41% of colonoscopies. Most frequently used scores were Mayo endoscopic score (90.56%) and SES-CD (56.03%) for ulcerative colitis and Crohn's disease, respectively. In addition, 79.11% of endoscopic reports failed to comply with all recommendations on endoscopic reporting for inflammatory bowel disease. CONCLUSIONS: A significant proportion of endoscopic reports of inflammatory bowel disease patients do not include the description of an endoscopic score to assess mucosal inflammatory activity in a real-world setting. This is also associated with a lack of compliance in recommended criteria for proper endoscopic reporting.

Gender differences in trajectories of health-related quality of life from childhood to adolescence in a 7-year follow-up study in a urban socially disadvantaged sample from Argentina.

PURPOSE: The transition from childhood to adolescence is a period of developmental changes, with social influences. Few previous studies have analyzed changes in health-related quality of life (HRQoL) during childhood and adolescence based on longitudinal studies in high-income countries. This study aimed to describe the evolution of HRQoL scores by gender in a school sample over a 7-year period in Argentina. METHODS: Prospective cohort of children attending fourth grade in public schools. HRQoL was measured using the KIDSCREEN-52 questionnaire. Trajectories of HRQoL were estimated for girls and boys through multilevel models, adjusted by socioeconomic status (SES). RESULTS: The study began in 2014 with a sample of 494 school children, reaching an 85.6% response rate in 2016, 31.4% in 2018, and 41.9% in 2021. Most of the predicted scores are negatively associated with linear age or/and quadratic age, suggesting a decrease in scores over the 7-year follow-up. Interactions between gender and age denote an increase in the differences in scores between girls and boys over time in favor of the latter. For the Index, Physical Well-being, Psychological Well-being, Autonomy, Parent relations, Social support and peers and Financial resources, individuals with medium or high SES have significantly higher scores than those with low SES. CONCLUSIONS: HRQoL scores decrease during the transition period from childhood to adolescence, with girls showing the greatest decrease. There were also socioeconomic inequalities in the evolution of HRQoL in a context characterized by social segregation and economic crisis, possibly aggravated by the COVID-19 pandemic.

Use of life cycle assessment for estimating impacts of waste-to-energy technologies in solid waste management systems: the case of Buenos Aires, Argentina.

Analysing municipal solid waste (MSW) management scenarios is relevant for planning future policies and actions toward a circular economy. Life cycle assessment (LCA) is appropriate for evaluating technologies of MSW treatment and their environmental impacts. However, in developing countries, advanced assessments are difficult to introduce due to the lack of technical knowledge, data and financial support. This research aims to assess the main potentialities of the introduction of waste-to-energy (WtE) systems in a developing Argentinean urban area considering the existing regulations about MSW recycling goals. The study was conducted with WRATE software and the proposed scenarios were current management, grate incineration of raw MSW and incineration of solid recovered fuel (SRF). In addition, a sensitivity analysis on the energy matrix was included. It was found that the production of SRF allows increasing the energy generation from waste by 200% and reducing the environmental impact of about 10% regarding the current MSW management system. Acidification Potential and Abiotic Depletion Potential were sensitive to changes in electricity mix. Results showed that if MSW reduction goals are achieved, changes in MSW composition will affect the performance of WtE plants and, in some cases, they will be not technically feasible. The outcomes of this study can be of interest for developing countries stakeholders and practitioners interested in LCA and sustainable MSW management.

Por primera vez, se elaboraron tablas de referencia de CF en escolares sanluiseños.

Sobreuso de ecografía transvaginal en un hospital universitario privado de Argentina: estudio de corte transversal / Transvaginal ultrasound overuse in a private university hospital in Argentina: a cross-sectional study

Introducción. Si bien contamos con recomendaciones basadas en la evidencia en contra de realizar tamizaje de cáncer ovárico con ecografía transvaginal debido a que aumenta el riesgo de resultados falsamente positivos y de cascadas diagnósticas, sin disminuir la mortalidad por esta enfermedad, su solicitud en mujeres sanas es frecuente. Sin embargo, no conocemos la magnitud de la implementación de esta práctica, que constituye un cuidado de bajo valor. Objetivo. Documentar el sobreuso de ecografías transvaginales realizadas en forma ambulatoria en un hospital universitario privado de Argentina. Métodos. Estudio de corte transversal de una muestra aleatoria de ecografías realizadas en forma ambulatoria durante 2017 y 2018. Mediante revisión manual de las historias clínicas, la solicitud de cada ecografía fue clasificada como apropiada cuando algún problema clínico justificaba su realización, o inapropiada cuando había sido realizada con fines de control de salud o por una condición clínica sin indicación de seguimiento ecográfico. Resultados. De un total de 1.997 ecografías analizadas, realizadas a 1.954 mujeres adultas (edad promedio 50 años),1.345 (67,4 %; intervalo de confianza [IC] 95 % 65,2 a 69,4) habían sido solicitadas en el contexto de un control de saludo sin un problema asociado en la historia clínica y otras 54 (8,3 %; IC 95 % 6,3 a 10,7), por condiciones de salud para las que no hay recomendaciones de realizar seguimiento ecográfico. Conclusiones. Esta investigación documentó una alta proporción de sobre utilización de la ecografías transvaginales en nuestra institución.

Background. Although we have evidence-based recommendations against screening for ovarian cancer with transvaginalultrasound because it increases the risk of false positive results and diagnostic cascades without reducing mortality from this disease, its request in healthy women is frequent. However, we do not know the magnitude of the implementation of this practice, which constitutes low-value care. Objective. To document the overuse of transvaginal ultrasounds performed on an outpatient basis in a private university hospital in Argentina. Methods. Cross-sectional study of a random sample of outpatient ultrasounds performed during 2017 and 2018. Through a manual review of the medical records, the request for each ultrasound was classified as appropriate when a clinical problem justified its performance or inappropriate when it was carried out for health control purposes or for a clinical condition that had no indication for ultrasound follow-up. Results. Of a total of 1997 ultrasounds analyzed, performed on 1954 adult women (average age 50 years), 1,345 (67.4 %;95 % confidence interval [CI] 65.2 to 69.4) had been requested in the context of a health check-up or without a documented problem in the medical history that would support its performance, and another 54 (8.3 %; 95 % CI 6.3 to 10.7), for health conditions for which there are no treatment recommendations to perform ultrasound follow-up. Conclusions. This research documented a high proportion of overuse of transvaginal ultrasound in our institution. Future research will allow us to understand the reasons that drive this practice and will help design interventions to reduce thislow-value care. (AU)

Impacto sanitario económico de dos modelos de provisión de prótesis desde un sistema público de salud / Financial and health impact of two models of providing prostheses in a public health system

[RESUMEN]. Objetivo. Comparar los resultados sanitarios y económicos de dos sistemas de adquisición de prótesis: un sistema tradicional en el cual la compra se inicia al solicitar el insumo versus un modelo de insumos en existencia denominado Banco de Prótesis. Métodos. Estudio descriptivo-analítico, en usuarios del Ministerio de Salud de la provincia de Buenos Aires, Argentina. Los pacientes pertenecían a dos grupos de estudio 1) prótesis provistas por vía tradicional del Sistema Informático para Adquisición y Contrataciones Hospitalarias (SIPACH); 2) prótesis provistas por Banco de Prótesis (BDP). Se limitó el análisis a prótesis endovasculares del tipo stent coronario y prótesis de cadera. Se utilizaron bases de datos oficiales gubernamentales. El periodo de estudio comprendió del 01/01/2018 hasta el 31/10/2022. Las variables analizadas fueron: edad, sexo, diagnóstico, hospital, tipo de implante o prótesis; fecha solicitud; fecha adquisición; precio unitario, costos directos e indirectos; costos promedio de la internación diaria, costo-efectividad e impacto presupuestario. Resultados. Se analizaron 4 106 solicitudes. En el sistema tradicional, 13,5% de los pacientes no consiguieron sus prótesis, hubo 50 días más de demora que con BDP, y los costos totales fueron superiores en SIPACH (stent coronarios +463%, prótesis de cadera +133%). El BDP ahorró US$ 3,2 millones anuales y evitó 22 muertes con la provisión temprana de prótesis endovasculares. Conclusiones. El BDP demostró superioridad al modelo tradicional de provisión de prótesis tanto en términos sanitarios, por lograr mayor acceso, acortar tiempos de espera y evitar muertes; como económicos, por reducir significativamente los precios unitarios y globales, logrando un notable ahorro en los presupuestos asignados.

[ABSTRACT]. Objective. Compare the health outcomes and financial outcomes of two systems for the procurement of prostheses: the traditional system, in which procurement is initiated when a product is requested; and the "Prosthesis Bank" model, based on a current inventory of supplies. Methods. Descriptive-analytical study of users of Ministry of Health services in the province of Buenos Aires, Argentina. The patients belonged to two study groups: 1) prostheses were provided through the traditional computerized system for hospital procurement and contracting, known as SIPACH; and 2) prostheses were provided by the Prosthesis Bank. The study was limited to endovascular prostheses (coronary stents) and hip prostheses. Official government databases were used. The study period was from 01/01/2018 to 31/10/2022. The variables analyzed were: age, sex, diagnosis, hospital, type of implant or prosthesis, date of request, date received, unit price, direct and indirect costs, average cost of daily hospitalization, cost-effectiveness, and budgetary impact. Results. A total of 4 106 applications were analyzed. In the traditional system: 13.5% of patients did not get their prostheses; it took 50 days longer than with the Prosthesis Bank; and total costs were higher in SIPACH (coronary stent, +463%; hip prosthesis, +133%). The Prosthesis Bank saved USD 3.2 million annually and prevented 22 deaths through early provision of endovascular prostheses. Conclusions. The Prosthesis Bank proved to be superior to the traditional model for providing prostheses, both in terms of health—by achieving better access, shortening waiting times, and avoiding deaths—and financially— by significantly reducing unit and overall prices, achieving significant savings in allocated budgets.

[RESUMO]. Objetivo. Comparar os resultados econômicos e sanitários de dois sistemas de aquisição de próteses: um sistema tradicional, no qual a compra é iniciada mediante solicitação, e um modelo em estoque chamado Banco de Próteses (BDP). Métodos. Estudo descritivo-analítico com usuários do Ministério da Saúde da província de Buenos Aires, Argentina. Os pacientes pertenciam a dois grupos de estudo: 1) próteses fornecidas pelo método tradicional do Sistema Informatizado de Aquisição e Contratações Hospitalares (SIPACH); e 2) próteses fornecidas pelo BDP. A análise se restringiu a próteses endovasculares do tipo stent coronariano e próteses de quadril. Foram utilizados bases de dados oficiais do governo. O período do estudo foi de 01/01/2018 a 31/10/2022. As variáveis analisadas foram: idade, sexo, diagnóstico, hospital, tipo de implante ou prótese; data de solicitação; data de aquisição; preço unitário, custos diretos e indiretos; custo médio diário de internação, relação custo-efetividade e impacto orçamentário. Resultados. Foram analisadas 4 106 solicitações. No sistema tradicional, 13,5% dos pacientes não recebe- ram as próteses e houve 50 dias a mais de espera do que pelo BDP. Além disso, os custos totais foram maiores no SIPACH (+463% no caso dos stents coronários e +133% para as próteses de quadril). O BDP economizou US$ 3,2 milhões ao ano e evitou 22 mortes com o fornecimento precoce de próteses endovasculares. Conclusões. O BDP demonstrou superioridade em relação ao modelo tradicional de fornecimento de próteses, tanto em termos sanitários, ao oferecer maior acesso, diminuir o tempo de espera e evitar mortes, quanto em termos econômicos, ao reduzir significativamente os preços unitários e totais, gerando economias significativas nos orçamentos alocados.
