RESUMEN

BACKGROUND: In breast cancer screening programmes, women may have discussions with a healthcare provider to help them decide whether or not they wish to join the breast cancer screening programme. This process is called shared decision-making (SDM) and involves discussions and decisions based on the evidence and the person's values and preferences. SDM is becoming a recommended approach in clinical guidelines, extending beyond decision aids. However, the overall effect of SDM in women deciding to participate in breast cancer screening remains uncertain. OBJECTIVES: To assess the effect of SDM on women's satisfaction, confidence, and knowledge when deciding whether to participate in breast cancer screening. SEARCH METHODS: We searched the Cochrane Breast Cancer Group's Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform on 8 August 2023. We also screened abstracts from two relevant conferences from 2020 to 2023. SELECTION CRITERIA: We included parallel randomised controlled trials (RCTs) and cluster-RCTs assessing interventions targeting various components of SDM. The focus was on supporting women aged 40 to 75 at average or above-average risk of breast cancer in their decision to participate in breast cancer screening. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion and conducted data extraction, risk of bias assessment, and GRADE assessment of the certainty of the evidence. Review outcomes included satisfaction with the decision-making process, confidence in the decision made, knowledge of all options, adherence to the chosen option, women's involvement in SDM, woman-clinician communication, and mental health. MAIN RESULTS: We identified 19 studies with 64,215 randomised women, mostly with an average to moderate risk of breast cancer. Two studies covered all aspects of SDM; six examined shortened forms of SDM involving communication on risks and personal values; and 11 focused on enhanced communication of risk without other SDM aspects. SDM involving all components compared to control The two eligible studies did not assess satisfaction with the SDM process or confidence in the decision. Based on a single study, SDM showed uncertain effects on participant knowledge regarding the age to start screening (risk ratio (RR) 1.18, 95% confidence interval (CI) 0.61 to 2.28; 133 women; very low certainty evidence) and frequency of testing (RR 0.84, 95% CI 0.68 to 1.04; 133 women; very low certainty evidence). Other review outcomes were not measured. Abbreviated forms of SDM with clarification of values and preferences compared to control Of the six included studies, none evaluated satisfaction with the SDM process. These interventions may reduce conflict in the decision made, based on two measures, Decisional Conflict Scale scores (mean difference (MD) -1.60, 95% CI -4.21 to 0.87; conflict scale from 0 to 100; 4 studies; 1714 women; very low certainty evidence) and the proportion of women with residual conflict compared to control at one to three months' follow-up (rate of women with a conflicted decision, RR 0.75, 95% CI 0.56 to 0.99; 1 study; 1001 women, very low certainty evidence). Knowledge of all options was assessed through knowledge scores and informed choice. The effect of SDM may enhance knowledge (MDs ranged from 0.47 to 1.44 higher scores on a scale from 0 to 10; 5 studies; 2114 women; low certainty evidence) and may lead to higher rates of informed choice (RR 1.24, 95% CI 0.95 to 1.63; 4 studies; 2449 women; low certainty evidence) compared to control at one to three months' follow-up. These interventions may result in little to no difference in anxiety (MD 0.54, 95% -0.96 to 2.14; scale from 20 to 80; 2 studies; 749 women; low certainty evidence) and the number of women with worries about cancer compared to control at four to six weeks' follow-up (RR 0.88, 95% CI 0.73 to 1.06; 1 study, 639 women; low certainty evidence). Other review outcomes were not measured. Enhanced communication about risks without other SDM aspects compared to control Of 11 studies, three did not report relevant outcomes for this review, and none assessed satisfaction with the SDM process. Confidence in the decision made was measured by decisional conflict and anticipated regret of participating in screening or not. These interventions, without addressing values and preferences, may result in lower confidence in the decision compared to regular communication strategies at two weeks' follow-up (MD 2.89, 95% CI -2.35 to 8.14; Decisional Conflict Scale from 0 to 100; 2 studies; 1191 women; low certainty evidence). They may result in higher anticipated regret if participating in screening (MD 0.28, 95% CI 0.15 to 0.41) and lower anticipated regret if not participating in screening (MD -0.28, 95% CI -0.42 to -0.14). These interventions increase knowledge (MD 1.14, 95% CI 0.61 to 1.62; scale from 0 to 10; 4 studies; 2510 women; high certainty evidence), while it is unclear if there is a higher rate of informed choice compared to regular communication strategies at two to four weeks' follow-up (RR 1.27, 95% CI 0.83 to 1.92; 2 studies; 1805 women; low certainty evidence). These interventions result in little to no difference in anxiety (MD 0.33, 95% CI -1.55 to 0.99; scale from 20 to 80) and depression (MD 0.02, 95% CI -0.41 to 0.45; scale from 0 to 21; 2 studies; 1193 women; high certainty evidence) and lower cancer worry compared to control (MD -0.17, 95% CI -0.26 to -0.08; scale from 1 to 4; 1 study; 838 women; high certainty evidence). Other review outcomes were not measured. AUTHORS' CONCLUSIONS: Studies using abbreviated forms of SDM and other forms of enhanced communications indicated improvements in knowledge and reduced decisional conflict. However, uncertainty remains about the effect of SDM on supporting women's decisions. Most studies did not evaluate outcomes considered important for this review topic, and those that did measured different concepts. High-quality randomised trials are needed to evaluate SDM in diverse cultural settings with a focus on outcomes such as women's satisfaction with choices aligned to their values.

RESUMEN

Introduction: We aimed to develop a decision aid to support shared-decision making between physicians and women with average breast cancer risk when deciding whether to participate in breast cancer screening. Methods: We included women at average risk of breast cancer and physicians involved in supporting the decision of breast cancer screening from an Academic Hospital in Buenos Aires, Argentina. We followed the International Patient Decision Aid Standards to develop our decision aid. Guided by a steering group and a multidisciplinary consultancy group including a patient advocate, we reviewed the evidence about breast cancer screening and previous decision aids, explored the patients' information needs on this topic from the patients' and physicians' perspective using semi-structured interviews, and we alpha-tested the prototype to determine its usability, comprehensibility and applicability. Results: We developed the first prototype of a web-based decision aid to use during the clinical encounter with women aged 40 to 69 with average breast cancer risk. After a meeting with our consultancy group, we developed a second prototype that underwent alpha-testing. Physicians and patients agreed that the tool was clear, useful and applicable during a clinical encounter. We refined our final prototype according to their feedback. Conclusion: We developed the first decision aid in our region and language on this topic, developed with end-users' input and informed by the best available evidence. We expect this decision aid to help women and physicians make shared decisions during the clinical encounter when talking about breast cancer screening.

RESUMEN

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. Futuras investigaciones permitirán comprender los motivos que impulsan esta práctica y ayudarán a diseñar intervenciones para disminuir estos cuidados de bajo valor. (AU)

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)

RESUMEN

Introducción: durante la pandemia de COVID-19 hubo un auge sin precedentes de la telemedicina, probablemente por la forzada adopción de tecnología ante las medidas restrictivas. El presente estudio se propuso comparar la interacción y la comunicación entre médicos de cabecera (MC) y pacientes, antes y durante el período de pandemia, en términos de consultas ambulatorias programadas y mensajes del Portal de Salud. Materiales y métodos: corte transversal con muestreo consecutivo de turnos programados y mensajes, ocurridos entre las semanas epidemiológicas (SE) 10 y 23, de 2019 y 2020, respectivamente. Se incluyeron 147 médicos del Servicio de Medicina Familiar y Comunitaria, y una cápita de 73 427 pacientes afiliados al Plan de Salud del Hospital Italiano de Buenos Aires. Se realizó análisis cuantitativo y cualitativo. Resultados: hubo una reducción del 70% de las consultas presenciales (de 76 375 en 2019 a 23 200 en 2020) y un aumento concomitante de teleconsultas (de 255 en la SE13 a 1089 en la SE23). En simultáneo, los mensajes aumentaron sustancialmente (de 28 601 en 2019 a 84 916 en 2020), con un inicio abrupto al comienzo del confinamiento, y una tendencia decreciente a lo largo del tiempo. Antes de la pandemia, el contenido estuvo relacionado con órdenes electrónicas de estudios complementarios, control de resultados, recetas de medicación crónica y/o interconsultas a especialistas, mientras que los dominios más frecuentes durante la pandemia fueron necesidades informativas epidemiológicas, como medidas preventivas para COVID-19, vacuna antineumocócica, vacuna antigripal, casos o sospechas, resultados de hisopados, entre otras. Conclusión: el auge de las tecnologías de la comunicación e información durante la pandemia permitió dar continuidad a los procesos asistenciales en salud pese al distanciamiento físico. Hubo mayor utilización de mensajería por necesidades informativas de los pacientes, y la relación médico-paciente se ha modificado. (AU)

Introduction: during the COVID-19 pandemic, there was an unprecedented boom in telemedicine, probably due to the forced adoption of technology in the face of restrictive measures. This study aimed to compare the interaction and communication between general practitioners and patients before and during the pandemic based on scheduled outpatient consultations and Health Portal messages. Materials and methods: Cross-sectional study with a consecutive sampling of scheduled appointments and messages, occurring between epidemiological weeks (EW) 10 and 23 of 2019 and 2020, respectively. We included 147 physicians from the Family and Community Medicine Service and a capita of 73427 patients affiliated with the Hospital Italiano de Buenos Aires health plan. We conducted a quantitative and qualitative analysis. Results: there was a 70% reduction in face-to-face consultations (from 76375 in 2019 to 23200 in 2020) and a concomitant increase in teleconsultations (from 255 in EW13 to 1089 in EW23). Concurrently, messages increased substantially (from 28601 in 2019 to 84916 in 2020), with an abrupt onset at the beginning of confinement and a decreasing trend over time. Before the pandemic, the content involved electronic orders for complementary studies, outcome monitoring, chronic medication prescriptions, or expert consultations. The most frequent domains during the pandemic were epidemiological information needs, such as preventive measures for COVID-19, pneumococcal vaccine, influenza vaccine, cases or suspicions, and swab results, among others. Conclusion: the rise of communication and information technologies during the pandemic allowed the continuity of healthcare processes despite the physical distance. There was increased use of messaging for patients' information needs, and the doctor-patient relationship has changed. (AU)

RESUMEN

Las guías de práctica clínica han contribuido a resolver un problema al sintetizar la evidencia y ponerla al alcance del profesional sanitario, pero su desarrollo e implementación creciente en los últimos años ha dado lugar a nuevos inconvenientes que aún no han sido resueltos. En este artículo editorial, la autora repasa cuestiones no tenidas en cuenta por las guías de práctica clínica, incluso aquellas consideradas de buena calidad de acuerdo a los estándares actuales, y reflexiona en especial sobre el uso del tiempo de los médicos en la consulta, aspecto desatendido que atenta contra la sustentabilidad del modelo actual de cuidado propuesto por estas recomendaciones. (AU)

Clinical practice guidelines have contributed to solving a problem by synthesizing the evidence and making it available to healthcare professionals, but their development and increasing implementation in recent years has given rise to new problems that have not yet been resolved. In this editorial article, the author reviews issues not taken into account by clinical practice guidelines, even those considered to be of good quality according to current standards, and reflects inparticular on the use of physicians' time in the consultation, a neglected aspect that undermines the sustainability of the current care model proposed by these recommendations.

RESUMEN

OBJECTIVES: To quantitatively document the degree of compliance of institutional messages broadcast on social networks with the recommendations of the National Cancer Institute (INC) in Argentina during October 2019, in the context of breast cancer prevention campaigns, and to qualitatively analyze the pictorial and textual elements that make up their dissemination pieces. MATERIALS AND METHODS: Quantitative and qualitative analysis of 171 dissemination pieces issued during October 2019 by 54 institutions, based on the evaluation of their compliance with INC recommendations, the description of the main discordant recommendations (quantitative analysis) and the qualitative analysis of 30 pieces. RESULTS: None of the issued messages mentioned potential screening harms. Only the messages of the National Ministry of Health complied completely with the INC recommendations, while the remaining ones recommended mammograms at younger ages or at shorter intervals. Breast self-examination was the most frequent recommendation among those who didn't comply. The images of female bodies linked to common stereotypes of sex and beauty, and paternalistic discourses appealing to fear and guilt were predominant. CONCLUSIONS: The messages broadcasted in the analyzed diffusion pieces did not comply with the INC recommendations, despite the fact that the latter are supported by scientific evidence. On the other hand, the messages reinforce sex and beauty stereotypes, guilt and the medical-hegemonic model.

OBJETIVOS.: Documentar cuantitativamente el grado de concordancia con las recomendaciones del Instituto Nacional del Cáncer (INC) de los mensajes institucionales emitidos en redes sociales de Argentina durante octubre de 2019, en el contexto de las campañas de prevención del cáncer mamario, y analizar cualitativamente los elementos icónicos y textuales que conforman sus piezas de difusión. MATERIALES Y MÉTODOS.: Análisis cuantitativo y cualitativo de 171 piezas de difusión emitidas durante octubre de 2019 por 54 instituciones, a partir de la evaluación de su concordancia con las recomendaciones del INC, la descripción de las principales recomendaciones discordantes (análisis cuantitativo) y el análisis cualitativo de 30 piezas. RESULTADOS.: Ninguno de los mensajes emitidos mencionó potenciales daños del tamizaje. Solamente los del Ministerio de Salud de la Nación fueron totalmente concordantes con las recomendaciones del INC, mientras que los restantes recomendaban realizar mamografías a edades más tempranas o a intervalos más breves. El autoexamen mamario fue la recomendación más frecuente entre las discordantes. Predominaron las imágenes de cuerpos femeninos vinculadas con los estereotipos predominantes de género y belleza, y los discursos paternalistas que apelan al miedo y a la culpa. CONCLUSIONES.: Los mensajes emitidos en las piezas de difusión analizadas no fueron concordantes con las recomendaciones del INC, a pesar de que estas últimas están respaldadas por evidencia científica. Por otro lado, los mensajes refuerzan los estereotipos de género y belleza, la culpa y el modelo médico-hegemónico.

RESUMEN

Argentina is an upper-middle income country located in South America with an estimated population of 46.2 million inhabitants. There is no unified research agenda or government initiatives encouraging the implementation and research of Shared Decision-Making (SDM). Our working group at the Family and Community Medicine Division of the Hospital Italiano de Buenos Aires is the leading centre for research and implementation of SDM in the country. The implementation strategy is articulated in undergraduate, postgraduate and continuous medical education. However, it is challenged by the professionals' perception that they are already doing it or lack time during consultations. We have advanced research to understand how to adapt tools to measure and implement SDM in our settings. Still, we face additional challenges related to funding, accessing diverse populations beyond the reach of our institution and incorporating patients in the co-production of research. While most of our efforts arise from the voluntary work of our healthcare professionals, we believe this is a strength since SDM research and implementation are then directly linked to patient care.

RESUMEN

Introduction: Last years, food insecurity is a raising problem in Argentina and is a key indicator of population health. The principal aim of this study was to determine food insecurity prevalence in a population of Buenos Aires suburbs, considering as secondary objectives: 1) to evaluate associated variables with food insecurity; 2) to perform provisional statistical validation of the Food Insecurity Experience Scale (FIES). Methods: It was conducted a descriptive, cross-sectional research study was conducted. Check the FIES survey in people over 15 years of age in the Barrio Santa María in Bajo Boulogne, San Isidro district, Buenos Aires. A probabilistic sampling was carried out. The data will be analyzed following the Rasch model proposed by the Food and Agriculture Organization of the United Nations. Results: 222 people were interviewed, finding a prevalence of moderate / severe food insecurity of 47.29% and severe of 6.57%. We found an independent association with a female head of household OR 2.22; (95%CI 1.27 to 3.87) and having more than 4 cohabitants in the home OR 2.24; (95%CI 1.25 to 4.02). The provisional validation of the FIES survey was carried out in our sample through the testing of the Rasch model assumptions. Conclusion: food insecurity is a problem present in our population. It was carried out the validation of an instrument to measure it, easy to apply and that allows valid comparisons between local and international measurements.

Introducción: La inseguridad alimentaria es una problemática en aumento en los últimos años en Argentina y resulta un indicador clave del estado de salud de la población. Este estudio se propuso determinar su prevalencia en una población del conurbano bonaerense planteándose como objetivos secundarios: 1) evaluar variables que se asocien con la inseguridad alimentaria; 2) realizar la validación estadística provisional de la Escala de la Inseguridad Alimentaria basada en la Experiencia (FIES). Materiales y métodos: Se realizó un estudio de investigación descriptivo, de corte transversal. Se utilizó la encuesta FIES en personas mayores de 15 años del Barrio Santa María en el Bajo Boulogne, partido de San Isidro, provincia de Buenos Aires. Se realizó un muestreo probabilístico. Se analizaron los datos siguiendo el modelo Rasch propuesto por la Organización de las Naciones Unidas para la Alimentación y la Agricultura. Resultados: Se entrevistaron 222 personas hallando una prevalencia de inseguridad alimentaria moderada/severa de 47,29% y severa de 6,57%. Se observó una asociación independiente con una jefatura de hogar femenina OR 2,22; (IC95% 1,27 a 3,87) y con tener más de 4 convivientes en el hogar OR 2,24; (IC95% 1,25 a 4,02). Se realizó la validación provisional de la encuesta FIES en nuestra muestra a través del testeo de las asunciones del modelo Rasch. Conclusión: la inseguridad alimentaria es un problema presente en nuestra población. Se realizó la validación de un instrumento para medirla, de sencilla aplicación y que permite realizar comparaciones válidas entre mediciones locales e internacionales.

RESUMEN

Estimar la frecuencia de cuadro de vías aéreas superiores (CVAS) como motivo de consulta no programada, describir el proceso de atención y explorar la variación tras la implementación de una nueva estrategia de gestión para la atención, así como el efecto en los indicadores de calidad y seguridad de atención. Cohorte retrospectiva que incluyó consultas por CVAS entre 01/01/2015 y 31/12/2016 de Demanda Espontánea (consultas de baja complejidad de la Central de Emergencia de Adultos), en el Hospital Italiano de Buenos Aires. La prevalencia global del período 2015-2016 resultó 12,01% (21.581/179.597). La intervención múltiple, resultó efectiva en términos de disminución de estudios complementarios (19% antes y 17% después con p=0,001), disminución de laboratorios (9% antes y 8% después con p=0,009), y reducción del tiempo de atención (media de 51 minutos antes y 42 minutos después, con p=0,001). No hubo diferencias significativas en la incidencia acumulada de reconsultas a los 7 días (12,72% antes y 13,11% después con p=0,400) ni en la tasa de internaciones a los 7 días (0,42% antes y 0,38% después con p=0,651) desde la consulta índice (primer consulta en guardia). En un sistema sobresaturado, se requiere fortalecer los sistemas de atención primaria que conforman la puerta de entrada de la salud para garantizar la correcta utilización de los recursos disponibles, la solicitud de estudios apropiados y la indicación correcta de antibióticos. Muchas lecciones aprendidas facilitaron la organización y la reestructuración necesarias durante la pandemia COVID-19 (AU)

To estimate upper respiratory tract infection (URTI) frequency as a reason for unscheduled consultation, to describe the care process and to explore the variation after the implementation of a new management strategy for care, as well as the effect on quality and security indicators of care. Retrospective cohort which included consecutive consultations by URTI between 01/01/2015 and 12/31/2016 for ambulatory clinic (low complexity consultations at the Emergency Department), at the Hospital Italiano de Buenos Aires. The prevalence for the period 2015-2016 was 12.01% (21,581/179,597). The multiple intervention was effective in terms of reduction of complementary studies (19% before and 17% after; p =0.001), reduction of laboratories (9% before and 8% after; p=0.009), and reduction of attention time (mean of 51 minutes before and 42 minutes after; p=0.001). During the follow up, there were no significant differences in the cumulative incidence of reconsultations at 7 days (12.72% before and 13.11% after; p=0.400) or in the rate of hospitalizations at 7 days (0.42% before and 0.38% after; p=0.651) from the index consultation. In an overcrowded system, it is necessary to strengthen the primary care systems that make up the gateway to health to guarantee the correct use of available resources, the request for appropriate studies and the correct indication of antibiotics. Many lessons learned facilitated the organization and restructuring of the Emergency Department needed during the COVID-19 pandemic (AU)

RESUMEN

INTRODUCCIÓN la Toma de Decisiones Compartidas (TDC) es un proceso mediante el cual el equipo de salud y el paciente trabajan juntos para tomar decisiones, basados en la mejor evidencia clínica y en las preferencias del paciente. en 2019 nuestro grupo de trabajo desarrolló una herramienta de ayuda para la toma de decisiones (hatd) para el tamizaje de cáncer de mama con mamografía. fue diseñada para usar durante la consulta médica, para mujeres de 40 a 69 años con riesgo promedio de cáncer de mama (http://decidirmamografia.com.ar/). OBJETIVOS evaluar la experiencia de uso de esta hatd, específicamente en la toma de decisiones informadas, tdc, conocimiento de beneficios y riesgos del tamizaje, conflicto decisional e intenciones de realizarse mamografía. RESULTADOS la media de edad fue de 56 años. Luego del uso de la herramienta, 12 de 27 pacientes (44%) lograron tomar una decisión informada, vs. una sola paciente (3%) que logró este objetivo antes del uso de la HATD, con una diferencia absoluta del 41% (I95%: 19 a 63, p=0.0010). Un 55% de las mujeres logró un conocimiento adecuado, vs un 7% antes del uso de la herramienta (DA 48%, IC 95%: 26 a 71; p=0.0002). Menos mujeres expresaron una actitud positiva hacia el tamizaje 37 vs 88% antes de la HATD (DA 51%; IC 95%: 74 a 29 p=0.0001); y menos mujeres tuvieron la intención de hacerse una mamografía (48 vs 74% antes de la HATD; DA: 26%; IC 95%: 0 a 52 p=0.0654). Sólo una paciente reportó un conflicto decisional alto, y el 80% de las pacientes consideró que había logrado la TDC. DISCUSIÓN la implementación de nuestra HATD demostró que un mayor número de mujeres logró tomar decisiones informadas, basadas en un adecuado conocimiento acerca de los beneficios y riesgos del tamizaje de cáncer de mama, y teniendo en cuenta sus propios valores y preferencias.
