The scope for radiology to contribute to the NHS net zero target: findings from a survey of radiology staff in the UK

To assess attitudes towards the climate emergency among radiology staff and to identify current practices that may contribute towards the National Health Service (NHS) net zero target. An online survey of radiology staff was conducted assessing current attitudes to the climate emergency. Further questions focused on staff travel, home working, virtual conferences, and recycling. Two hundred and forty-two responses were received from all staff groups within radiology. There were high levels of concern about the climate emergency among radiology staff. Active travel accounts for a relatively small proportion of commuting related to provision of radiology services. Some energy-saving measures are implemented commonly in radiology departments but these are likely to account for only a small proportion of energy use within a department. There is significant scope for reducing the carbon footprint of radiology services by reducing travel, both for work and for radiology education. We discuss the potential for large savings related to energy-saving measures.

Staff eye lens dose in interventional radiology and cardiology in Finland

PurposeThe aim of this study was to investigate the eye lens and whole-body radiation doses to interventional radiology and cardiology staff in two Finnish hospitals. MethodsSimultaneous measurements of personal dose equivalent quantities Hp(3) and Hp(10) were conducted in clinical conditions during different radiological and cardiological interventional procedures. In order to study the feasibility to estimate eye lens dose with Hp(10) measured over the protective apron or thyroid shield, the ratio between measured Hp(3) and Hp(10) was investigated. Results and conclusionsApplying the obtained ratio on Hp(10) records from national dose register showed that only a small number of interventional radiologists and cardiologists in Finland may exceed eye lens equivalent dose levels of 20 mSv per year or 100 mSv in five consecutive years, but likely do not exceed 50 mSv in a single year. For the most Finnish interventionalists, the eye lens dose is well below 10 mSv per year. Nurses and radiographers assisting in interventions are, on average, less exposed than interventionalists, and will not exceed 20 mSv per year. Based on our results, Hp(10) measured over the protective apron or thyroid shield provides a conservative estimate of the eye lens dose for interventional radiologists and cardiologists, provided that appropriate protective glasses are used.

A web-based cross-sectional study assessing the impact of COVID-19 on the mental health of radiology staff in Saudi Arabia.

The 2019 novel coronavirus pandemic has not only created massive public health issues, it has also produced excessive psychological disorders in healthcare professionals, including radiology staff. The aim of this study is to assess the risk perception and mental health of radiology staff in Saudi Arabia during the COVID-19 pandemic. The researcher asked radiology staff to complete an online Google Forms questionnaire, between June 10, 2020 and June 17, 2020, which contained demographic data and self-designed questions related to anxiety, insomnia, depressive symptoms, and mental health services during the pandemic. A total of 168 radiology staff participated in the study. The results indicated that 53.05% and 57.14% of the participants were experiencing mild to severe symptoms of anxiety and depression, respectively. Moreover, 47.02% of the participants were experiencing insomnia symptoms. Among all the participants, only 16.61% had received psychological materials from their hospital during the pandemic, while 22.02% had accessed online psychological assistance techniques. The health of roughly one-third (30.95%) of the participants was worse than it had been before the pandemic. COVID-19 is a source of mental health disorders for healthcare professionals, particularly radiology staff. The findings of this study indicate that more than 70% of radiology staff in Saudi Arabia are concerned about insufficient protective measures and the risk of infection. In addition, a large percentage of them have experienced mental health disorders, such as anxiety, insomnia, and depression. Regular mental healthcare services are required to decrease the negative impact of the pandemic and enhance the overall mental health of the radiology staff.

Determining the Effect of the Picture Archiving and Communication System (PACS) on Different Dimensions of Users' Work.

The impact of the picture archiving and communication system (PACS) on healthcare costs, information access, image quality, and user workflow has been well studied. However, there is insufficient evidence on the effect of this system on different dimensions of the users' work. The objective of this study was to evaluate the impact of the PACS on different dimensions of users' work (external communication, service quality, user intention to use the PACS, daily routine, and complaints on users) and to compare the opinions of different groups of users about the PACS. This study was performed on the PACS users (n = 72) at Kerman University of Medical Sciences, including radiologists, radiology staff, ward heads, and physicians. Data were collected using a questionnaire consisting of two parts: demographic information of the participants and 5-point Likert scale questions concerning the five dimensions of users' work. Data were analyzed using descriptive statistics, ANOVA, and Pearson's correlation coefficient statistical tests. The mean of scores given by the PACS users was 4.31 ± 0.86 for external communication, 4.18 ± 0.96 for user intention to use the PACS, 3.91 ± 0.7 for service quality, 3.16 ± 0.56 for daily routine, and 3.08 ± 1.05 for complaints on users. Radiologists and radiology staff had a more positive opinion about the PACS than other clinicians such as physicians (P < 0.01, CI = 95%). Factors such as user age (P < 0.01, CI = 95%), job (P < 0.001, CI = 95%), work experience (P < 0.001, CI = 95%), and PACS training method (P=0.037, CI = 95%) were related to the impact of the PACS on different dimensions of users' work. This study showed that the PACS has a positive effect on different dimensions of users' work, especially on external communication, user intention to use the system, and service quality. It is recommended to implement PACSs in medical centers to support users' work and to maintain and strengthen the capabilities and functions of radiology departments.

Epidemiological Study on the Prevalence of Staphylococcus aureus PVL Gene Among Healthy Community in Al- Karkh and Al -Rusaffa Districts Baghdad, Iraq

Five hundred nasal swabs were taken from normal medical staff and public in the city of Baghdad. Several identification parameters were used to recognize the bacterial isolates. S. aureus isolations form nasal swabs were identified using morphology and VITECK 2 system. Polymerase chain reaction (PCR) was employed to determine PVL (Panton–Valentine leukocidin ) gene in S. aureus. The data showed no significant evidence on the relationship between PVL gene presence and gender and age of the studied groups. There was no relation between the prevalence of PVL gene in the age groups of 21-30 years (p=0.328) and 31-40 years (p=0.682).&#x0D; The results showed that 38.4% and 37.5% S. aureus isolates were isolated from nurses working at Baghdad Teaching Hospital and AL-Yarmouk Teaching Hospital, respectively, while, doctors, pharmacists, and radiology staff were negative (0.00%).&#x0D; There was no significant difference between hospital staff and community in AL-Karkh (p=0.838) and in AL-Rusafa (p=0.118).

Impact of the incorrect use of lead drapes on staff and patient doses in interventional radiology

To evaluate the usefulness of commercially available scatter reduction drapes in mitigating staff exposure in interventional radiology and the potential harmful effects of drape malpositioning in terms of exposure levels to both patients and staff. An anthropomorphic phantom was irradiated on an angiography device under three scenarios: no drape and correct and incorrect drape positioning. Different levels of incorrect drape positioning relative to the field-of-view (FOV) were evaluated: slight, mild and severe. Real-time dosimeter systems (positioned on the operator’s eye, chest and thyroid) were used to evaluate accumulative doses and dose rates. Different obstruction levels were evaluated and compared to the observer’s perception. Additionally, patient exposure was evaluated for all scenarios using a dose area product (DAP). Up to a mild obstruction, by using the drape a dose reduction of up to 86% was obtained while a severe obstruction produced a 1000% increase in exposure, respectively for all dosimeter positions compared to the use of no drape. A similar order of magnitude was observed for patient exposure. Good agreement was obtained for the observer perception of the FOV obstruction up to 25% of the FOV; for larger obstructions, an overestimate of the obstruction was observed. Patient lead drapes can reduce staff doses in interventional radiology procedures even when mildly malpositioned and obscuring the FOV. Special attention to protective drape positioning is necessary, since the severe obstruction of the FOV results in a large increase in both operator and patient exposure.

The prophylactic roles of dietary antioxidants for medical radiology workers: A mini-review

Antioxidants play a very crucial naturally role in our bodies. Still, unfortunately, that is not enough. We need to compensate for the shortage we face by increasing the dietary antioxidants as exogenous sources, especially when there is an exogenous factor-induced oxidative stress as with the medical radiology staff because how much ionizing radiation they are exposed to exceeds the primitive dose limit by the International Commission on Radiological Protection (ICRP). Thus, a suitable uptake of minerals, vitamins, and Combinations of dietary antioxidants through the daily diet and balanced it remains the promising approach without exceeding the uptakes doses that could reverse the positive effects of this approach. This review focuses on the present knowledge about dietary antioxidant sources, mechanisms, effects of the cell components. It critically investigates studies examining the effects of dietary antioxidant supplementation and its role among medical radiology workers.

Effect of training on resident inter-reader agreement with American College of Radiology Thyroid Imaging Reporting and Data System.

BACKGROUNDThe American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) was introduced to standardize the ultrasound characterization of thyroid nodules. Studies have shown that ACR-TIRADS reduces unnecessary biopsies and improves consistency of imaging recommendations. Despite its widespread adoption, there are few studies to date assessing the inter-reader agreement amongst radiology trainees with limited ultrasound experience. We hypothesize that in PGY-4 radiology residents with no prior exposure to ACR TI-RADS, a statistically significant improvement in inter-reader reliability can be achieved with a one hour training session.AIMTo evaluate the inter-reader agreement of radiology residents in using ACR TI-RADS before and after training.METHODSA single center retrospective cohort study evaluating 50 thyroid nodules in 40 patients of varying TI-RADS levels was performed. Reference standard TI-RADS scores were established through a consensus panel of three fellowship-trained staff radiologists with between 1 and 14 years of clinical experience each. Three PGY-4 radiology residents (trainees) were selected as blinded readers for this study. Each trainee had between 4 to 5 mo of designated ultrasound training. No trainee had received specialized TI-RADS training prior to this study. Each of the readers independently reviewed the 50 testing cases and assigned a TI-RADS score to each case before and after TI-RADS training performed 6 wk apart. Fleiss kappa was used to measure the pooled inter-reader agreement. The relative diagnostic performance of readers, pre- and post-training, when compared against the reference standard.RESULTSThere were 33 females and 7 males with a mean age of 56.6 ± 13.6 years. The mean nodule size was 19 ± 14 mm (range from 5 to 63 mm). A statistically significant superior inter-reader agreement was found on the post-training assessment compared to the pre-training assessment for the following variables: 1. “Shape” (k of 0.09 [slight] pre-training vs 0.67 [substantial] post-training, P < 0.001), 2. “Echogenic foci” (k of 0.28 [fair] pre-training vs 0.45 [moderate] post-training, P = 0.004), 3. ‘TI-RADS level’ (k of 0.14 [slight] pre-training vs 0.36 [fair] post-training, P < 0.001) and 4. ‘Recommendations’ (k of 0.36 [fair] pre-training vs 0.50 [moderate] post-training, P = 0.02). No significant differences between the pre- and post-training assessments were found for the variables 'composition', 'echogenicity' and 'margins'. There was a general trend towards improved pooled sensitivity with TI-RADS levels 1 to 4 for the post-training assessment while the pooled specificity was relatively high (76.6%-96.8%) for all TI-RADS level.CONCLUSIONStatistically significant improvement in inter-reader agreement in the assigning TI-RADS level and recommendations after training is observed. Our study supports the use of dedicated ACR TI-RADS training in radiology residents.

Learning to See: Using Mixed or Methods to Model Radiology Staff Workload and Support Decision Making in CT

Demand for Computer Tomography (CT) is growing year on year and the population of Ireland is increasingly aging and ailing. Anecdotally, radiology staff reported increasing levels of workload associated with the patient profile. In this paper, we propose a framework combining discrete event simulation (DES) modeling and soft systems methodologies (SSM) for use in healthcare which captures the staff experience and metrics to evidence workload. The framework was applied in a single-scanner CT department, which completes circa 6000 examinations per year. The scanner case load consists of unscheduled work [inpatient (IP) and emergency department (ED)] and scheduled work [outpatient (OP) and general practitioner (GP)]. The three stage framework is supported by qualitative and quantitative methods and uses DES as a decision support tool. Firstly, workflow mapping and system dynamics are used to conceptualize the problem situation and instigate a preliminary data analysis. Secondly, SSM tools are used to identify components for a DES model and service improvement scenarios. Lastly, the DES model results are used to inform decision-making and identify a satisficing solution. Data from the DES model provided evidence of the differing workload (captured in staff time) for the IP and OP cohorts. For non-contrast examinations, inpatient workload is 2.5 times greater than outpatient. Average IP process delays of 11.9 min were demonstrated compared to less than 1 min for OP. The findings recommend that OP and IP diagnostic imaging be provided separately, for efficiency, workload management and infection control reasons.

Estimating staffing requirements using workload indicators of staffing need at Braun District Hospital in Morobe Province, Papua New Guinea

BackgroundPapua New Guinea has seen some improvements in health indicators over the past years, but the pace of improvements is not as robust as expected. The Health Services Plan for Braun District Hospital redevelopment identified the importance of reflecting the hospital’s role in the broader health system, particularly in upgrading the services to service a bigger population. In August 2020, the hospital was upgraded from a health centre—level 3 to a district hospital level 4. The need for assessing human resources for health requirements for this level of care was thus necessary.MethodsThe National Department of Health approved the use of the workload indicators of staffing need as the best tool to support in estimating staff requirements for the newly upgraded hospital. The focus was on clinical and non-clinical staff. Using already developed workload components and activity standards by the expert working groups for level 4 facilities, we visited the facility and collected data through interviews with the Lutheran Health Services representative, hospital management and staff. The technical task force reviewed daily registers, monthly reports and the data in the electronic national health information systems. The information collected was analysed using the workload indicators of staffing need software and interpreted.ResultsThere were staffing shortages among the clinical staff like the medical officers, nursing officers, health extension officers, pharmacists, radiology staff unit and in the laboratory staff. Shortages among the non-clinical staff were recorded by the cashiers, security officers, drivers and boat skippers. The results showed that the facility lacks a medical laboratory technologist, pharmacists and a medical imaging technologist. The community health workers in this facility are utilized in all the areas where shortages are registered to multitask.ConclusionThe results from this WISN study provide evidence for basing staffing decisions on. The WISN results from Braun District Hospital show that the facility requires a total of 33 inpatient nurses against the existing 21 inpatient nurses thus giving a staff gap of − 12 and a WISN ratio of 0.67. It is thus recommended that the hospital management prioritizes recruitment of nurses or if no resources, reassign one of the outpatient nurses to alleviate the pressure among the inpatient nurses or the extra theatre nurses to offer some services in the inpatient wards. WISN results can help managers make decisions such as change of health facility status from a health centre to a district hospital.

Radiologist Knowledge of Artificial Intelligence on Diagnostic radiology: A survey-based study

Background &amp; Aims: Artificial intelligence (AI) has lately made significant advancements in perception, enabling machines to represent complicated facts, many clinical procedures were automated using AI, transforming radiology from a perceptually subjective trade to a mathematically calculable area. The radiologists participating in the residency program don't know how to employ artificial intelligence in clinical settings or how it fits into diagnostic radiology. So, this study is an attempt to determine the knowledge of AI among radiologists. Material and Methods: A online survey was done using google forms circulated through Whatsapp groups of radiologists for the assessment of knowledge regarding AI among them. The questionnaire consists of ten questions related to AI usefulness and knowledge of AI in diagnostic radiology. Data was transformed into an excel sheet and analyzed using descriptive and inferential statistics by SPSS software Result: The knowledge of AI was better among respondents and senior consultant radiologists had good knowledge regarding artificial intelligence and junior residents were lacking in some areas. Conclusions: The level of AI expertise among radiology staff members seriously influences their readiness to learn, apply, and modify this technology in clinical settings.

Machine learning and deep learning-based Natural Language Processing for auto-vetting the appropriateness of Lumbar Spine Magnetic Resonance Imaging Referrals

Manual vetting of radiology referrals is an essential daily task to ensure the appropriateness of the received referrals. Such tasks require sufficient clinical experience and may challenge the radiology staff. With the emerging of artificial intelligence (AI) technology and advancement in natural language processing NLP, most of the available machine learning-based NLP models targeted research cohort building and healthcare quality. Other healthcare management tasks such as auto-vetting radiology referrals have not been adequately encoded. Furthermore, challenges, including class imbalance and lack of direct comparison with humans, are yet to be investigated sufficiently. In this study, a set of machine learning and deep learning models were developed for auto-vetting of lumbar spine magnetic resonance imaging LSMRI referrals as indicated or not indicated for scanning using referrals from two hospitals. The impact of applying one of the text augmentation techniques on the models' performance has been investigated. In addition, the performance of four different feature extraction techniques has been critically analyzed. Moreover, a comparison has been conducted between the developed models with two expert radiologists who were not involved in establishing the gold standard labels using an unseen dataset. The results show that the models’ performances significantly improved with the augmented data, with an increase in F1 scores ranging from 1% to 8%. Support vector machine with bag of words achieved the highest AUC reaching 0.99. Convolutional neural network model achieved the second-highest model with AUC = 0.97. All models outperformed the two expert radiologists when comparisons were conducted on the unseen dataset.

Assessment of Level of Awareness Towards Radiation Protection Among the Staff Working at Angiography Suite at Public Hospitals

Introduction Several challenges with radiation protection and safety culture in radiology departments needs to be addressed as few studies done in this aspect in our country. Especially with regard to the awareness about radiation protection, hazards, dosimetry usage and measurement. Objective The objective of this study is to find knowledge about radiation exposure hazard and practices among various auxiliary staff working in radiation units. Material and Methods Cross-sectional study done by using stratified random sampling method. A questionnaire made to check the awareness level of the radiological staff regarding radiation protection working in angiography suite. The questionnaire had two parts with various questions about radiation protection measures and safety related knowledge for staff and patient. Data collected from angiography suite of three public sector hospitals of Lahore, Pakistan. All the data entered in statistical package for the social science (SSPS) version 16 and analyzed for statistically significant outcomes. Results Total of 67 staff members were included in this study from three different public sector hospitals, 55.2% were males 44.77% were females. Twenty-nine (29) persons belonged to the age group of 20-30-years. Twenty (20) doctors, 21 nurses, 12 radiographers and 14 paramedical staff were included. 89.55% staff members were aware of radiation hazard. 55.22% had training on radiation protection and 44.77%. 56.71% were aware of dosimeter. Only 16% were aware of as low as reasonably achievable (ALARA). Conclusion The radiological staff members were partially aware about radiation hazards and radiation safety. They were lacking from training and workshops. Essential steps required to develop nationwide strategies for improving the situation and maintaining a safe working environment.

Role of CXR and HRCT in diagnosing COVID-19, a descriptive cross-sectional study, at a tertiary care hospital in Pakistan

ABSTRACT &#x0D; Objectives: Objectives of this study are to do the analysis of chest X-ray and High-resolution CT scan findings in patients who are clinical suspects of COVID-19 infection. The other objective is to classify the radiological findings in mild, moderate or severe diseases according to BSTI criteria for chest X-ray and CTSS for high-resolution CT scan.&#x0D; Methods: This is a cross-sectional descriptive study. A group of 50 patients who were clinically suspected cases of COVID-19 infection, presented to Corona flu filter clinic of Holy Family Hospital (HFH) or admitted to corona isolation wards were included. The time duration of the study was from 15 May 2020 to 15 June 2020. Patients labelled as clinically suspected cases were having positive contact with confirmed positive (based upon positive PCR) patients. Recent travel history from the area having an outbreak. They were having clinical signs/symptoms of fever, cough, and shortness of breath, lethargy and loss of sense of smell or taste. CXR and HRCT was the investigation of choice for all the 50 patients. I also did PCR to make a correlation with the other two tests. All radiological findings were analyzed based upon Fleischner society glossary of terms for thoracic imaging. Two radiologists then assessed CXRs findings based upon BSTI criteria. They marked those CXR findings as low, moderate and high probability for COVID-19 infection. HRCT findings were analyzed using CT-SS, and researchers labelled outcomes as mild, moderate and severe disease. &#x0D; Results: Out of 50 patients, 33(66%) were males, and 17(34%) were females. Mean age was 51 with ages ranging from 30-72 years. Presenting complaints were fever in 42(84%) patients, cough in 37(74%), lethargy in 33(66%), shortness of breath in 41(82%) and loss of sense of smell and taste in 21(42%) patients. Out of these 50, 32(72%) were having positive PCR for COVID-19 infection. On CXR 5(10%) patients showed classic findings which were highly probable for COVID-19. 19(38%) patients showed intermediate results for COVID-19, 7(14%) patients had a low probability of COVID-19 infection on CXRS. Out of 50, 19(38%), patients showed normal CXR with no evidence of COVID-19 infection. We did HRCT of the same patients on the same day; it showed 21(42%)patients with mild disease,23(46%)patients with moderate disease and 6(12%)patients with the severe disease according to CTSI.HRCT of 3(6%)patients was ok with no evidence of illness in bilateral lungs. &#x0D; &#x0D; Conclusion: The role of radiology is crucial in the diagnosis of this viral illness. CXR, with its ability to detect changes of COVID-19 in lungs, should be used as a first-line imaging modality in clinically suspected patients. Moreover, it should also be used for follow up of patients with COVID-19. HRCT is very sensitive in the diagnosis of COVID-19 infection in its milder forms. Due to lack of its widespread availability in countries with inadequate medical facilities, it was not the primary imaging tool/screening tool. Due to risk of infection to radiological staff as well as non-covid-19 patients due to surface contact, due to reduced infection control issues, due to increased burden of ionizing radiations in patients. All these factors limit the role of HRCT as a primary imaging modality for COVID-19 infection

Technical feasibility and efficacy of a standard needle magnetization system for ultrasound needle guidance in thyroid nodule-targeting punctures: a phantom study.

PurposeThe aim of this study was to assess the feasibility and efficacy of an ultrasound needle guidance system (NGS) based on standard needle magnetization in a phantom study of thyroid nodule (TN)-targeting punctures.MethodsSix trainees and a staff radiologist performed TN-targeting punctures with or without the NGS in phantom models (group 1, experience <50 cases; group 2, experience ≥50 cases and <100 cases; group 3, experience ≥100 cases of TN-targeting punctures). The feasibility, technical success rate, number of punctures, and procedure time were recorded.ResultsThe feasibility of NGS was 98.6% (138/140). In group 1, the technical success rate increased from 60.0%±8.2% to 80.0%±8.2% when the NGS was used (P=0.046), with a reduction in the number of punctures from 2.2 to 1.2 (P=0.005). In group 2, the rate changed from 95.0%±5.8% to 100.0%±0.0% with the NGS (P=0.157), with a minimal decrease in the number of punctures from 1.1 to 1.0 (P=0.157). The procedure time significantly decreased in both groups (P=0.041 and P=0.010, respectively) when the NGS was used. In group 3, there were no significant differences in the technical success rate and the number of punctures according to whether the NGS was used (P=0.317 and P=0.317, respectively).ConclusionNGS using standard needle magnetization is technically feasible and has potential to improve the efficacy of TN-targeting punctures for less-experienced operators, especially beginners, according to the findings of this phantom study.

Distance From Critical Pelvic Structures: Radiographic Comparison of High Submuscular and Space of Retzius IPP Reservoir Placement Techniques

ObjectiveTo evaluate the distance from critical pelvic structures (CPS, defined as bladder and iliac vessels) among inflatable penile prosthesis (IPP) reservoirs placed into the space of Retzius (SOR) and high submuscular (HSM) locations using cross-sectional imaging. IPP reservoir placement into the HSM location has been proposed as a strategy to prevent injury due to greater distance from CPS. MethodsOur institutional database was retrospectively reviewed to identify men who underwent IPP insertion between 2007 and 2020 and had available cross-sectional abdominopelvic imaging after the time of surgery. Patients were grouped based on reservoir placement technique (SOR vs. HSM). Staff radiologists blinded to placement technique evaluated reservoir position to determine the shortest distance between CPS and the reservoir and if a mass effect was present on CPS. Variables were analyzed using chi-squared, Fisher's exact, and student's T-tests as indicated. ResultsAmong 1,010 IPP cases performed during the study interval, 139 (13%) were imaged. Compared with SOR reservoirs (n = 32), HSM reservoirs (n =107) were significantly less likely to induce a mass effect on the bladder (72 vs. 9%, P = <.01) or iliac vessels (34 vs. 4%, P = <.01) and were located roughly 5 times further from the bladder (10 ± 22 vs. 49 ± 36 mm, P = <.01) and iliac vessels (5 ± 9 vs. 23 ± 26 mm, P = <.01). ConclusionThis study radiographically confirms that IPP reservoirs are located significantly further away from CPS following HSM placement compared to SOR placement.

Collar Badge Lens Dose Equivalent Values among United States Physicians Performing Fluoroscopically Guided Interventional Procedures

PurposeTo describe the range of occupational badge dose readings and annualized dose records among physicians performing fluoroscopically guided interventional (FGI) procedures using job title information provided by the same 3 major medical institutions in 2009, 2012, and 2015. Materials and MethodsThe Radiation Safety Office of selected hospitals was contacted to request assistance with identifying physicians in a large commercial dosimetry database. All entries judged to be uninformative of occupational doses to FGI procedure staff were excluded. Monthly and annualized doses were described with univariate statistics and box-and-whisker plots. ResultsThe dosimetry data set of interventional radiology staff contained 169 annual dose records from 77 different physicians and 698 annual dose records from 455 nonphysicians. The median annualized lens dose equivalent values among physicians (11.9 mSv; interquartile range [IQR], 6.9–20.0 mSv) was nearly 3-fold higher than those among nonphysician medical staff assisting with FGI procedures (4.0 mSv; IQR, 1.8–6.7 mSv) (P < .001). During the study period, without eye protection, 25% (23 of 93) of the physician annualized lens dose equivalent values may have exceeded 20 mSv; for nonphysician medical staff, this value may have been exceeded 3.5% (6 of 173) of the time. However, these values did not account for eye protection. ConclusionsThe findings from this study highlight the importance of mitigating occupational dose to the eyes of medical staff, particularly physicians, performing or assisting with FGI procedures. Training on radiation protection principles, the use of personal protective equipment, and patient radiation dose management can all help ensure that the occupational radiation dose is adequately controlled.
