Real-world experience of secukinumab dose optimization in moderate-to-severe psoriasis. Retrospective, single-center series of 11-patients. / Experiencia en la práctica clínica tras la optimización de la dosis del secukinumab en la psoriasis moderada-severa. Serie retrospectiva de 11 casos.

Psoriasis is a chronic immune-mediated inflammatory systemic disease that mainly affects skin. Secukinumab is an anti-interleukin-17A agent approved for the treatment of moderate-to-severe psoriasis that has probed efficacy and safety both in clinical trials and in real-world practice. Secukinumab data sheet dose approved in maintenance response phase for adults with psoriasis is 300mg monthly. Recently, dose optimization for biologic therapies in psoriasis has been proposed in order to individualise the treatment looking for better treatment adherence and better cost-effectiveness due to their high costs. In this scenario, we report our real-world experience in dose optimization for patients with moderate-to-severe psoriasis treated with Secukinumab.

Dependence of Europe's most threatened mammals on movement to adapt to climate change.

Current rates of climate change and gloomy climate projections confront managers and conservation planners with the need to integrate climate change into already complex decision-making processes. Predicting and prioritizing climatically stable areas and the areas likely to facilitate adaptive species' range adjustments are important stages in maximizing conservation outcomes and rationalizing future land management. I determined, for the most threatened European terrestrial mammal species, the spatial adaptive trajectories (SATs) of highest expected persistence up to 2080. I devised simple spatial network indices for evaluation of species in those SATs: total persistence; proportion of SATs that offer in situ adaptation (i.e., stable refugia); number of SATs converging in a site; and relationship between SAT convergence and persistence and protected areas, the Natura 2000 and Emerald networks, and areas of low human disturbance. I compared the performance of high-persistence SATs with a scenario in which each species remained in the areas with the best climatic conditions in the baseline period. The 1000 most persistence SATs for each of the 39 species covered one fifth of Europe. The areas with the largest adaptive potential (i.e., high persistence, stability, and SAT convergence) did not always overlap for all the species. Predominantly, these regions were located in southwestern Europe, Central Europe, and Scandinavia, with some occurrences in Eastern Europe. For most species, persistence in the most climatically suitable areas during the baseline period was lower than within SATs, underscoring their reliance on adaptive movements. Importantly, conservation areas (particularly protected areas) covered only minor fractions of species persistence among SATs, and hubs of spatial climate adaptation (i.e., areas of high SAT convergence) were seriously underrepresented in most conservation areas. These results highlight the need to perform analyses on spatial species' dynamics under climate change.

Los mamíferos más amenazados de Europa y su dependencia del movimiento para adaptarse al cambio climático Resumen La tasa actual del cambio climático y las proyecciones climáticas pesimistas confrontan a los gestores y a los planeadores de la conservación con la necesidad de integrar este cambio a la ya de por sí compleja toma de decisiones. La predicción y priorización de áreas con estabilidad climática y áreas con probabilidad de facilitarles ajustes adaptativos de distribución a las especies son etapas importantes para maximizar los resultados de conservación y racionalizar la gestión futura de las tierras. Determiné las trayectorias espaciales adaptativas (TEA) para la mayoría de los mamíferos terrestres más amenazados de Europa con la persistencia esperada más alta hasta el 2080. Diseñé los siguientes índices de redes espaciales simples para la evaluación de especies en aquellas TEA: persistencia total, proporción de TEA que brindan adaptación in situ (refugios estables), número de TEA que convergen en un sitio y relación entre la convergencia de TEA y la persistencia con las áreas protegidas, las redes Natura 2000 y Emerald y las áreas de poca perturbación humana. Comparé el desempeño de las TEA de gran persistencia con un escenario en el que las especies permanecían dentro de las áreas con las mejores condiciones climáticas en el periodo de línea base. Las mil TEA más persistentes para cada una de las 39 especies cubrieron la quinta parte de Europa. Las áreas con el mayor potencial adaptativo (es decir, gran persistencia, estabilidad y convergencia de TEA) no siempre se traslaparon para todas las especies. Estas regiones predominaron en el suroeste de Europa, Europa Central y Escandinavia, con algunas ocurrencias en el este de Europa. Para la mayoría de las especies, la persistencia de las áreas con el mejor clima posible durante el periodo de línea base fue menor que dentro de las TEA, lo que resalta su dependencia por los movimientos adaptativos. Destaca que las áreas de conservación (en particular las áreas protegidas) cubrieron sólo pequeñas fracciones de la persistencia de las especies entre las TEA y los núcleos de adaptación climática (es decir, las áreas de gran convergencia de TEA) contaban con muy poca representación dentro de la mayoría de las áreas de conservación. Estos resultados enfatizan la necesidad de realizar análisis de las dinámicas espaciales de las especies bajo el cambio climático.

Outpatient parenteral antibiotic therapy (OPAT) through elastomeric continuous infusion pumps in a real-life observational study: Characteristics, safety, and efficacy analysis.

INTRODUCTION: This study aimed to present real-life data on the use, efficacy, and safety of administering antibiotic therapy through portable elastomeric pumps (pEP) in the outpatient setting. METHODS: This retrospective observational cohort study was conducted from January 2020 to May 2023 in a large academic hospital in Rome, Italy. All patients receiving antibiotic therapy via pEP were included up to a follow-up period of 90 days after the end of antibiotic therapy. The primary outcome was the treatment response. Secondary endpoints were adverse events attributable to the drug administered, the vascular catheter, or the infection itself. RESULTS: Of the 490 patients referred to our outpatient parenteral antibiotic therapy (OPAT) unit, 94 (19.2%) received antibiotic therapy via pEP and were included in the final analysis. The most frequently treated infections were those involving bone and prosthetics, including spondylodiscitis (n=27; 28.8%). Most infections were due to Pseudomonas aeruginosa (n=55; 48.3%). Cefepime (n=32; 34.0%), piperacillin/tazobactam (n=29; 30.9%), ceftolozane/tazobactam (n=7; 7.5%), and oxacillin (n=7; 7.5%) were the most frequently administered antibiotics. The infection cure rate reached 88.3% (n=83). 12 patients (12.8%) reported adverse events, of which half (6.4%) were drug-related and half (6.4%) were line-related. CONCLUSIONS: OPAT through portable elastomeric infusion pumps proved to be safe and effective. It also contributed to the reduction of healthcare costs, fully respecting the principles of personalized medicine. This strategy has emerged as a promising tool for antibiotic stewardship and infection control.

10 years of prehabilitation: From theory to clinical practice.

In recent years, prehabilitation has generated high expectations as an innovative preoperative strategy to enhance clinical outcomes following surgery. Several studies have demonstrated that multimodal programs are effective in improving patients' health status and cardiopulmonary reserve, allowing them to undergo surgery in better conditions and, consequently, reducing the incidence of postoperative complications. Most publications describe proof-of-concept studies, and literature about their implementation is more limited. The implementation of these programs requires new resources and significant organizational effort. In this paper, we share our experience implementing a multimodal prehabilitation program as a mainstream service at a tertiary hospital. Although there are still many unknowns regarding the optimal selection of patients, as well as the duration and components of the program, this article describes our journey in this field, aiming to provide insight for teams interested in developing a similar project.

Diseño de un panel de indicadores para programas de optimización del uso de antimicrobianos en los Servicios de Urgencias / Design of a panel of indicators for antibiotic stewardship programs in the Emergency Department

Objetivo: desarrollar un panel de indicadores para monitorizar la actividad de los programas de optimización del uso de antimicrobianos en los servicios de urgencias. Métodos: un grupo multidisciplinar formado por expertos en el manejo de la infección en urgencias y en la implantación de programas de optimización de uso de antimicrobianos (PROA) evaluó una propuesta de indicadores utilizando una metodología Delphi modificada. En una primera ronda, cada uno de los expertos clasificó la relevancia de cada indicador propuesto en 2 dimensiones (repercusión asistencial y facilidad de implantación) y 2 atributos (nivel de priorización y periodicidad de medida). La segunda ronda se realizó a partir del cuestionario modificado de acuerdo con las sugerencias planteadas y nuevos indicadores sugeridos por los participantes. Los expertos efectuaron modificaciones en el orden de priorización y calificaron los nuevos indicadores propuestos de la misma manera que en la primera ronda. Resultados: se propusieron un total de 61 potenciales indicadores divididos en 4 grupos: indicadores de consumo, microbiológicos, de proceso y de resultado. Tras el análisis de las puntuaciones y los comentarios realizados en la primera ronda, 31 indicadores fueron clasificados como de alta prioridad, 25 de prioridad intermedia y 5 de baja prioridad. Además se generaron 19 nuevos indicadores. Tras la segunda ronda, se mantuvieron los 61 indicadores inicialmente propuestos y adicionalmente se incorporaron 18 nuevos: 11 como de alta prioridad, 3 como de intermedia y 4 como de baja prioridad. Conclusiones: los expertos consensuaron un panel de indicadores PROA adaptado a los servicios de urgencias priorizados por nivel de relevancia como un elemento de ayuda para el desarrollo de estos programas, que contribuirá a monitorizar la adecuación del uso de antimicrobianos en estas unidades.(AU)

Objective: To develop a panel of indicators to monitor antimicrobial stewardship programs activity in the emergency department. Methods: A multidisciplinary group consisting of experts in the management of infection in emergency departments and the implementation of antimicrobial stewardship programs (ASP) evaluated a proposal of indicators using a modified Delphi methodology. In the first round, each expert classified the relevance of each proposed indicators in two dimensions (healthcare impact and ease of implementation) and two attributes (prioritization level and frequency). The second round was conducted based on the modified questionnaire according to the suggestions raised and new indicators suggested.

Programas de optimización del uso de antimicrobianos en los servicios de urgencias españoles: Estudio PROA-URG / Antibiotic stewardship programs in the Spanish emergency services: PROA-URG Study

Introducción: Los programas de optimización de antimicrobianos (PROA) son herramientas clave en la adecuación de estos fármacos. La información disponible sobre la aplicación e indicadores para monitorizar estos programas en urgencias es limitada. El objetivo del estudio es conocer el grado de implantación de programas PROA en los servicios de urgencias, así como el uso de antimicrobianos en estas unidades. Material y métodos. Estudio multicéntrico retrospectivo. Se envió una invitación a todos los participantes del grupo de trabajo de farmacéuticos de urgencias REDFASTER-SEFH. Se utilizó un cuestionario de 21 ítems, contestado por un equipo formado por especialistas en los servicios de farmacia hospitalaria, urgencias, enfermedades infecciosas y microbiología. Resultados. 18 hospitales completaron la encuesta. Catorce (77,8%) disponían de un responsable PROA en la unidad. El valor de DDD por 1000 ingresos osciló entre 36,5 y 400,5 (mediana 100,4 [RIQ:57,2-157,3]). El grupo de carbapenémicos y macrólidos presentó una amplia variabilidad. Únicamente seis (33,3%) hospitales disponían de informe anual de resistencias específico para urocultivos y hemocultivos en urgencias. El porcentaje de multirresistentes en urocultivos fue del 12,5% y en hemocultivos del 12,2%. El porcentaje de adecuación en bacteremia de acuerdo con el resultado del hemocultivo fue del 81,0% (RIQ:74,6-85,0%), y en infección urinaria del 78,0% (RIQ:71,5-88,0%). Conclusiones. Pese a la existencia de responsables PROA, actividades formativas y guías de tratamiento en urgencias, la información sobre el uso de antimicrobianos y el perfil de resistencias en estas unidades es limitado. Futuras actividades han de ir encaminadas a mejorar la información sobre los resultados PROA propios para estas unidades. (AU)

Introduction: Antimicrobial stewardship programs (ASP) have become a key tool in the adaptation of these drugs to the health system. The information available on the application and indicators used in these programs in emergency departments is scarce. The objective of this study is to know theextent of ASP implementation in the emergency departments, as well as the use of antimicrobials in these units. Material and methods. Multicenter retrospective study. An invitation was sent to all participants of the REDFASTER-SEFH emergency pharmacist working group. A questionnaire was used consisting of 21 items, answered by a team made up of a pharmacist, emergency room specialist, infectious disease specialist and microbiologist. Results. Eighteen hospitals completed the survey. Fourteen (77.8%) had an ASP manager. The DDD value per 1000 admissions ranged between 36.5 and 400.5 (median: 100.4 [IQR:57.2-157.3]). Both carbapenem and macrolide group presented wide variability in use. Six (33.3%) hospitals had an annual report on the specific resistance profile for urine and blood cultures. The percentage of multi-drug resistant strains in urine cultures was 12.5% and in blood cultures 12.2%. The percentage of adequacy in the bacteremia treatment was 81.0% (IQR:74.6-85.0%), while in urinary tract infections was 78.0% (IQR:71.5-88.0). Conclusions: Despite the existence of ASP members in emergency services, as well as the training activity and local guidelines is common. knowledge of the use of antimicrobials and resistances is limited. Future activities must be aimed at improving information about the ASP results in these units. (AU)

Resumen ejecutivo del documento de consenso sobre el manejo de la anemia perioperatoria en España / Executive summary of the consensus document on the management of perioperative anemia in Spain

La anemia perioperatoria constituye un factor independiente de riesgo de morbimortalidad posoperatoria. Sin embargo, persisten barreras conceptuales, logísticas y administrativas que dificultan la implementación generalizada de protocolos para su manejo. El coordinador del proyecto convocó a un grupo multidisciplinar de ocho profesionales para elaborar un documento de consenso sobre el manejo de la anemia perioperatoria, con base a en serie puntos claves (PCs) relativos a su prevalencia, consecuencias, diagnóstico y tratamiento. Estos PCs fueron evaluados utilizando una escala Likert de 5 puntos, desde «totalmente en desacuerdo [1]» a «totalmente de acuerdo [5]». Cada PC se consideró consensuado si recibía una puntuación de 4 o 5 por al menos siete participantes (> 75%). A partir de los 36 PCs consensuados, se construyeron algoritmos diagnóstico-terapéuticos que pueden facilitar la implementación de programas de identificación precoz y manejo adecuado de la anemia perioperatoria, adaptados a las características de las instituciones hospitalarias de nuestro país.(AU)

Perioperative anemia is an independent risk factor for postoperative morbidity and mortality. However, conceptual, logistical and administrative barriers persist that hinder the widespread implementation of protocols for their management. The project coordinator convened a multidisciplinary group of 9 experienced professionals to develop perioperative anemia management algorithms, based on a series of key points (KPs) related to its prevalence, consequences, diagnosis and treatment. These KPs were assessed using a 5-point Likert scale, from “strongly disagree [1]” to “strongly agree [5]”. For each KP, consensus was reached when receiving a score of 4 or 5 from at least 7 participants (>75%). Based on the 36 KPs agreed upon, diagnostic-therapeutic algorithms were developed that we believe can facilitate the implementation of programs for early identification and adequate management of perioperative anemia, adapted to the characteristics of the different institutions in our country.(AU)

Rapid diagnostic tests for dengue would reduce hospitalizations, healthcare costs and antibiotic prescriptions in Spain: A cost-effectiveness analysis / Los tests de diagnóstico rápido para dengue reducirían las hospitalizaciones, los costes sanitarios y la prescripción de antibióticos en España: un análisis de coste-efectividad

Background: Current gold standard diagnostic techniques for dengue are expensive and time-consuming. Rapid diagnostic tests (RDTs) have been proposed as alternatives, although data about their potential impact in non-endemic areas is scarce. Methods: We performed a cost-effectiveness analysis comparing the costs of dengue RDTs to the current standard of care for the management of febrile returning travelers in Spain. Effectiveness was measured in terms of potential averted hospital admissions and reduction of empirical antibiotics, based on 2015–2020 dengue admissions at Hospital Clinic Barcelona (Spain). Results: Dengue RDTs were associated with 53.6% (95% CI: 33.9–72.5) reduction of hospital admissions and were estimated to save 289.08–389.31€ per traveler tested. Moreover, RDTs would have avoided the use of antibiotics in 46.4% (95% CI: 27.5–66.1) of dengue patients. Discussion: Implementation of dengue RDTs for the management of febrile travelers is a cost-saving strategy that would lead to a reduction of half of dengue admissions and a reduction of inappropriate antibiotics in Spain.(AU)

Introducción: El actual gold standard para el diagnóstico de dengue se basa en técnicas caras y que requieren tiempo. Los tests de diagnóstico rápido (TDR) se han propuesto como una posible alternativa, aunque los datos sobre su posible impacto en áreas no endémicas son escasos. Métodos: Realizamos un análisis de coste-efectividad comparando los costes del uso de TDR para dengue con el manejo habitual de viajeros con fiebre en España. Para medir la efectividad se estimaron las hospitalizaciones potencialmente evitables y la reducción de antibióticos empíricos de acuerdo con las hospitalizaciones por dengue entre 2015-2020 en el Hospital Clínic Barcelona (España). Resultados: El uso de TDR para dengue se asoció con una reducción de 53.6% (IC 95%: 33.9–72.5) de las hospitalizaciones y un ahorro de 289.08-389.31€ por viajero testado. Además, el uso de TDR hubiese evitado el tratamiento de antibióticos en 46.4% (IC 95%: 27.5–66.1) de los casos de dengue. Discusión: La implementación de TDR de dengue para el manejo de viajeros con fiebre es una medida de reducción de gastos que disminuiría a la mitad los ingresos hospitalarios por dengue y supondría una reducción del uso inapropiado de antibióticos en España.(AU)

Anticipating anthropogenic threats in acquiring new protected areas.

Biodiversity continues to decline despite protected area expansion and global conservation commitments. Biodiversity losses occur in existing protected areas, yet common methods used to select protected areas ignore postimplementation threats that reduce effectiveness. We developed a conservation planning framework that considers the ongoing anthropogenic threats within protected areas when selecting sites and the value of planning for costly threat-mitigating activities (i.e., enforcement) at the time of siting decisions. We applied the framework to a set of landscapes that contained the range of possible correlations between species richness and threat. Accounting for threats and implementing enforcement activities increased benefits from protected areas without increasing budgets. Threat information was valuable in conserving more species per spending level even without enforcement, especially on landscapes with randomly distributed threats. Benefits from including threat information and enforcement were greatest when human threats peaked in areas of high species richness and were lowest where human threats were negatively associated with species richness. Because acquiring information on threats and using threat-mitigating activities are costly, our findings can guide decision-makers regarding the settings in which to pursue these planning steps.

Anticipación de las amenazas antropogénicas durante la adquisición de áreas protegidas nuevas Resumen La biodiversidad sigue declinando a pesar de la expansión de áreas protegidas y los compromisos mundiales con la conservación. La pérdida de la biodiversidad ocurre en las áreas protegidas existentes, y todavía los métodos comunes usados para seleccionar las áreas protegidas ignoran las amenazas posteriores a la implementación, las cuales reducen la efectividad. Desarrollamos un marco de planeación de la conservación que considera las amenazas antropogénicas actuales dentro de las áreas protegidas durante la selección de sitios y el valor de la planeación de actividades mitigantes costosas, como la aplicación, al momento de decidir. Aplicamos nuestro marco a un conjunto de paisajes que comprende el rango de correlaciones posibles entre las amenazas y la riqueza de especies. Si consideramos las amenazas y la implementación de actividades de aplicación, los beneficios de las áreas protegidas incrementan sin incrementar el presupuesto. La información sobre las amenazas fue importante para la conservación de especies por nivel de gasto incluso sin la aplicación, especialmente en paisajes con amenazas distribuidas de forma azarosa. Los beneficios de incluir la información sobre las amenazas y la aplicación fueron mayores cuando las amenazas humanas llegaron a su tope en áreas con gran riqueza de especies y alcanzaron su punto más bajo cuando las amenazas humanas estaban asociadas negativamente con la riqueza de especies. Ya que es costoso adquirir información sobre las amenazas y mitigar las amenazas con actividades, nuestros descubrimientos pueden informar a los tomadores de decisiones con respecto al entorno para seguir los pasos de la planeación.

Design of a panel of indicators for antibiotic stewardship programs in the Emergency Department. / Diseño de un panel de indicadores para programas de optimización del uso de antimicrobianos en los Servicios de Urgencias.

OBJECTIVE: To develop a panel of indicators to monitor antimicrobial stewardship programs activity in the emergency department. METHODS: A multidisciplinary group consisting of experts in the management of infection in emergency departments and the implementation of antimicrobial stewardship programs (ASP) evaluated a proposal of indicators using a modified Delphi methodology. In the first round, each expert classified the relevance of each proposed indicators in two dimensions (healthcare impact and ease of implementation) and two attributes (prioritization level and frequency). The second round was conducted based on the modified questionnaire according to the suggestions raised and new indicators suggested. Experts modified the prioritization order and rated the new indicators in the same manner as in the first round. RESULTS: 61 potential indicators divided into four groups were proposed: consumption indicators, microbiological indicators, process indicators, and outcome indicators. After analyzing the scores and comments from the first round, 31 indicators were classified as high priority, 25 as intermediate priority, and 5 as low priority. Moreover, 18 new indicators were generated. Following the second round, all 61 initially proposed indicators were retained, and 18 new indicators were incorporated: 11 classified as high priority, 3 as intermediate priority, and 4 as low priority. CONCLUSIONS: The experts agreed on a panel of ASP indicators adapted to the emergency services prioritized by level of relevance. This is as a helpful tool for the development of these programs and will contribute to monitoring the appropriateness of the use of antimicrobials in these units.

Optimización de la exploración eco Doppler mediante la manipulación de los controles del equipo (knobology); segunda parte / Doppler ultrasound exploration optimization by manipulating the controls of the equipment: knobology; part two

La ecografía Doppler es una modalidad diagnóstica que depende de un operador indispensable por disponibilidad, eficacia, coste y no invasividad. Además de conocimientos anatómicos y clínicos, exige un mínimo conocimiento de sus principios físicos y tecnológicos. Este artículo intenta repasar y esquematizar cómo ajustar las principales aplicaciones del equipo en la exploración Doppler mediante los botones y los controles (knobology). Complementa a la primera parte ya editada, en la que se explicaban los ajustes en la exploración en modo B. Realizar una exploración con una postura adecuada, que evite lesiones en el explorador (ergonomía), permite también aumentar nuestro rendimiento laboral. Conocer, entrenar y ajustar las funciones del eco Doppler de forma ordenada teniendo en cuenta al paciente y el estudio indicado hará que nuestras exploraciones sean más sencillas, rápidas, seguras y precisas.(AU)

Doppler ultrasound is an operator-dependent diagnostic modality, essential due to availability, efficacy, costs and non-invasive test. In addition to anatomical and clinical knowledge, it requires a minimum knowledge of its physical and technological principles. This article attempts to review and outline how to adjust the main applications of the equipment in Doppler scanning, using the buttons and controls (knobology). It complements the first part already edited, where the adjustments in the exploration in B mode were explained.Carrying out an examination with a suitable posture, which avoids injuries to the explorer (ergonomics), also allows us to increase our work performance. Knowing, training and adjusting the echo Doppler functions in an orderly manner, considering the patient and the indicated study, will make our examinations easier, faster, safer and more precise.(AU)

Niveles de referencia diagnósticos en equipos de radiografía dental en Bogotá, Colombia

Introducción: Las radiografías dentales son una de las exposiciones médicas más frecuentes a la radiación ionizante. El uso de radiación ionizante está asociado a un riesgo probable de desencadenar efectos biológicos adversos y posibles daños a la salud del paciente. Para evitar que los pacientes reciban dosis innecesariamente altas durante estas exposiciones, la Comisión Internacional de Protección Radiológica recomienda la utilización de los niveles de referencia para diagnóstico, como una herramienta efectiva de ayuda a la optimización de la protección radiológica de los pacientes. Objetivo: Estimar los niveles de referencia para diagnóstico en radiografía dental intraoral y panorámica en la ciudad de Bogotá, D. C. Metodología: Se evaluaron los parámetros de exposición radiográficos de los equipos y la calidad de imagen en 68 equipos de radiografía dental periapical y 23 equipos de radiografía panorámica. Se estimaron las magnitudes dosimétricas de kerma incidente en aire (Kai) en equipos intraorales para la radiografía de un maxilar molar de un adulto y el producto kerma aire-área (PKA) en equipos de radiografía panorámica en un examen de un adulto estándar. Resultados: El tercer cuartil de la distribución de kerma incidente en aire para radiografía intraoral fue de 3,3 mGy y del producto kerma aire-área para radiografía panorámica fue de 103,9 mGycm2. En la distribución de frecuencias de kerma incidente en aire para radiografía intraoral, el porcentaje más alto de equipos estuvo en el rango de 2,0-3,0 mGy. En la distribución de frecuencias del producto kerma aire-área para los equipos de radiografía panorámica, el porcentaje más alto de equipos estuvo en el rango de 60 a 80 mGycm2. Discusión: Las instituciones consideradas para establecer los Niveles de Referencia para Diagnóstico en este estudio contaron con una adecuada calidad de la imagen evaluada con un maniquí dental, pero las variaciones en las dosis de radiación entre instituciones señalan la necesidad de implementar herramientas que contribuyan a la optimización de las prácticas. Conclusiones: Se recomienda usar los valores de los niveles de referencia para diagnóstico encontrados en esta investigación para optimizar la protección radiológica en las exposiciones radiológicas dentales, y se espera que este estudio sirva de base para nuevas investigaciones en las demás ciudades del país.

Introduction: Dental X-rays are one of the most frequent medical exposures to ionizing radiation. The use of ionizing radiation is associated with a probable risk of triggering adverse biological effects and possible damage to the patient's health. To prevent patients from receiving unnecessarily high doses during these exposures, the International Commission on Radiological Protection recommends the use of diagnostic reference levels as an effective tool to help optimize radiological protection for patients. Objective: To estimate diagnostic reference levels in intraoral and panoramic dental radiography in the city of Bogotá, D.C. Methodology: In 68 periapical dental radiography equipment and 23 panoramic radiography equipment, the radiographic exposure parameters of the equipment and image quality were evaluated. The dosimetric magnitudes of incident air kerma (Ka,i) in intraoral equipment for the radiography of a maxillary molar of an adult and the air kerma-area product (PKA) in panoramic radiography equipment in a standard adult examination were estimated. Results: The third quartile of the incident air kerma distribution for intraoral radiography was 3,3 mGy and the air kerma-area product for panoramic radiography was 103,9 mGycm2. In the frequency distribution of incident air kerma for intraoral radiography, the highest percentage of equipment was in the range of 2,0-3,0 mGy, and in the frequency distribution of the air kerma-area product for equipment of panoramic radiography, the highest percentage of the equipment was in the range of 60 to 80 mGy cm2. Discussion: The institutions considered to establish the diagnostic reference levels in this study had an adequate quality of the image evaluated with a dental phantom, but the variations in radiation doses between institutions indicate the need to implement tools that contribute to the optimization of the practices. Conclusions: It is recommended to use the values of the diagnostic reference levels found in this research to optimize radiological protection in dental radiological exposures, and it is expected that this study will serve as a basis for further research in other cities of the country.
