“…Medical radiologists themselves underestimate the radiation doses associated with a CT scan by 50-500 times [14] use ionizing radiation [15]. Such faulty knowledge is transferred directly onto patients when they discuss the reasons for having a medical imaging test and its related risks with medical specialists [16][17][18][19][20]. Nonetheless, no one knows the real level of awareness and perception of the risk arising from ionizing radiation in patients receiving diagnostic radiological procedures.…”

A B S T R A C TIntroduction: The European Directive 2013/59/EURATOM requires patient radiation dose information to be included in the medical report of radiological procedures. To provide effective communication to the patient, it is necessary to first assess the patient's level of knowledge regarding medical exposure. The goal of this work is to survey patients' current knowledge level of both medical exposure to ionizing radiation and professional disciplines and communication means used by patients to garner information. Material and Methods: A questionnaire was designed comprised of thirteen questions: 737 patients participated in the survey. The data were analysed based on population age, education, and number of radiological procedures received in the three years prior to survey. Results: A majority of respondents (56.4%) did not know which modality uses ionizing radiation. 74.7% had never discussed with healthcare professionals the risk concerning their medical radiological procedures. 70.1% were not aware of the professionals that have expertise to discuss the use of ionizing radiation for medical purposes, and 84.7% believe it is important to have the radiation dose information stated in the medical report. Conclusion: Patients agree with new regulations that it is important to know the radiation level related to the medical exposure, but there is little awareness in terms of which modalities use X-Rays and the professionals and channels that can help them to better understand the exposure information. To plan effective communication, it is essential to devise methods and adequate resources for key professionals (medical physicists, radiologists, referring physicians) to convey correct and effective information.

“…Numerosos trabajos han demostrado el gran incremento de los estudios radiológicos diagnósticos en paí-ses desarrollados, en particular la TC (63 millones de estudios anuales en Estados Unidos), que representa el 60% de la radiación artificial, debiéndose este hecho a múltiples causas: aumento de la disponibilidad de tomó-grafos, demanda de estudios por los propios pacientes, medicina defensiva, repetición de estudios por falta de información, entre otros (5)(6)(7)(8) (figura 2). A pesar de las crecientes preocupaciones con respecto a la exposición a la radiación médica, todavía hay una conciencia limitada acerca de los riesgos de cáncer inducido (9) . Una encuesta realizada en Estados Unidos entre los médicos de emergencia e imagenólogos encontró que el 75% de los mismos subestimó los riesgos de la radiación por la TC.…”

ResumenIntroducción: el uso creciente de la tomografía computada produce un aumento de la dosis colectiva con el potencial riesgo de las radiaciones ionizantes. El objetivo del trabajo fue determinar la frecuencia de estudios tomográficos repetidos y estimar la dosis de radiación acumulada en el período 2014/2017 de una muestra de pacientes asistida durante julio/agosto de 2017 en el Hospital de Clínicas.Método: se incluyeron pacientes que en julio/agosto de 2017 concurrieron al Departamento de Imagenología del Hospital de Clínicas, a quienes su médico tratante indicó la realización de una tomografía computada. Se trató de un estudio descriptivo, longitudinal, retrospectivo. Se completó una planilla con datos demográficos y del procedimiento. Se realizó la búsque-da de estudios tomográficos previos en el sistema de archivo de imágenes médicas y registro de informes de los últimos tres años.Resultados: en la muestra se incluyeron 110 pacientes; 59 (54,1%) se hicieron más de una tomografía, siendo abdomen y pelvis las regiones más estudiadas. Siete pacientes (6,4%) superaron el umbral de dosis de 100 mSv y 16 (14,5%) recibieron dosis entre 50 y 100 mSv. A su vez, 23 pacientes (20,9%) se hicieron más de cuatro tomografías, es decir, en promedio más de una al año.Conclusiones: la tomografía computada es una herramienta beneficiosa para el diagnóstico siempre y cuando se use racionalmente haciendo un balance entre riesgo/beneficio. Se debe tomar conciencia de los riesgos vinculados a la dosis acumulada en múltiples estudios tomográficos.

“…6 However, many providers have little understanding of the carcinogenic risks of imaging examinations, or how to communicate those risks. 6 Usage of CT clearly has its benefits. In the emergency department (ED), increased accessibility and use of multidetector CT has greatly improved patient outcomes through improved diagnostic accuracy, which results not only in more appropriate treatment but also more conservative management, such as in cases where patients present with traumatic injuries or other acute conditions.…”

Communicating radiation risk to patients and referring physicians in the emergency department setting

Heightened awareness about the radiation risks associated with CT imaging has increased patients' wishes to be informed of these risks, and has motivated efforts to reduce radiation dose and eliminate unnecessary imaging. However, many ordering providers, including emergency physicians, are ill prepared to have an informed discussion with patients about the cancer risks related to medical imaging. Radiologists, who generally have greater training in radiation biology and the risks of radiation, often do not have a face-to-face relationship with the patients who are being imaged. A collaborative approach between emergency physicians and radiologists is suggested to help explain these risks to patients who may have concerns about getting medical imaging.
