Background High rates of provider burnout and turnover, as well as staffing shortages, are creating crises within radiology departments. Identifying ways to support health care workers, such as the Positively Energizing Leadership program, is important during these ongoing crises. Purpose To identify the relationship between leadership behaviors and workplace climate and health care worker outcomes (ie, burnout, intent to leave, and engagement) and to determine whether the positive leadership program could improve workplace climate and health care worker outcomes. Materials and Methods This prospective study involved two parts. First, a web-based survey was administered to faculty and staff in a breast imaging unit of a large academic medical center in February 2021 to identify relationships between leadership behaviors and workplace climate and health care worker outcomes. Second, a web-based survey was administered in February 2023, following the implementation of a positive leadership program, to determine improvement in engagement and reduction of burnout and intent to leave since 2021. Multiple regression, the Sobel test, Pearson correlation, and the t test were used, with a conservative significance level of P < .001. Results The sample consisted of 88 respondents (response rate, 95%) in 2021 and 85 respondents (response rate, 92%) in 2023. Leadership communication was associated with a positive workplace climate (ß = 0.76, P < .001) and a positive workplace climate was associated with improved engagement (ß = 0.53, P < .001), reduction in burnout (ß = -0.42, P < .001), and reduction in intent to leave (ß = -0.49, P < .001). Following a 2-year positive leadership program, improved perceptions were observed for leadership communication (pretest mean, 4.59 ± 1.51 [SD]; posttest mean, 5.80 ± 1.01; t = 5.97, P < .001), workplace climate (pretest mean, 5.09 ± 1.43; posttest mean, 5.77 ± 1.11; t = 3.35, P < .001), and engagement (pretest mean, 5.27 ± 1.20, posttest mean, 5.68 ± 0.96; t = 2.50, P < .01), with a reduction in burnout (pretest mean, 2.69 ± 0.94; posttest mean, 2.18 ± 0.74; t = 3.50, P < .001) and intent to leave (pretest mean, 3.12 ± 2.23; posttest mean, 2.56 ± 1.84; t = 1.78, P < .05). Conclusion After implementation of a positive leadership program in a radiology department breast imaging unit, burnout and intention to leave decreased among health care workers, while engagement increased. © RSNA, 2024 See also the editorial by Thrall in this issue.

Overnight radiology (ONR) is necessary for providing timely patient care but poses unique professional and personal challenges to the radiologists. Maintaining a sustainable, long-term overnight radiology program hinges on the retention of radiologists who grasp the institutional workflow and can adeptly navigate inherent disruptions while consistently delivering high-quality patient care. Design of radiology shifts can significantly impact the performance and well-being of radiologists, with downstream implications for patient care and risk management. We provide a narrative review of literature to make recommendations for optimally designing ONR shifts, with a focus on professional and personal challenges pertinent to overnight radiologists and system-based risk mitigation strategies.

INTRODUCTION: New Zealand's shortage of medical imaging technicians has intensified due to factors like illness, the pandemic, and an ageing workforce. Addressing staff retention issues requires attention to intrinsic factors like workplace satisfaction and work-life balance. Self-rostering has proven effective in healthcare by enhancing work-life balance, job satisfaction, and retention, but it has not been implemented widely in radiology. This study aimed to explore the perceptions, benefits, and challenges of implementing AI-generated self-rostering in a radiology department through simulated trials. METHODS: This study simulated an AI-generated roster in a regional New Zealand radiology department, engaging 23 staff members. A mixed-methods approach included surveys and discussion groups. Community-based participatory action methodology guided discussion groups and informed modifications. RESULTS: The AI-generated self-rostering method demonstrated success by meeting a high percentage of shift preferences while fulfilling service demands. Participants perceived potential benefits in work-life balance and autonomy, though uncertainties persisted regarding implementation and fairness. Despite staff reservations, we found that an AI-generated self-rostering system may be fairer than manual self-rostering, while saving radiology staff time and cost. CONCLUSION: AI-generated self-rostering offers an innovative solution to an old problem. This self-rostering system provides a fair way for staff to have a say in the shifts they do, which increases feelings of work-life balance and autonomy. In this simulation, AI-generated self-rostering was well received, and most staff were receptive to moving to pilot the programme. IMPLICATIONS FOR PRACTICE: Self-rostering could be a potential solution to staff retention issues in radiology; we recommend a pilot study is implemented. When switching to self-rostering, departments should consider implementing one-on-one support systems to assist staff with entering preferences. Education is essential to encourage staff understanding and cooperation.

Climate change adversely affects the well-being of humans and the entire planet. A planetary health framework recognizes that sustaining a healthy planet is essential to achieving individual, community, and global health. Radiology contributes to the climate crisis by generating greenhouse gas (GHG) emissions during the production and use of medical imaging equipment and supplies. To promote planetary health, strategies that mitigate and adapt to climate change in radiology are needed. Mitigation strategies to reduce GHG emissions include switching to renewable energy sources, refurbishing rather than replacing imaging scanners, and powering down unused scanners. Radiology departments must also build resiliency to the now unavoidable impacts of the climate crisis. Adaptation strategies include education, upgrading building infrastructure, and developing departmental sustainability dashboards to track progress in achieving sustainability goals. Shifting practices to catalyze these necessary changes in radiology requires a coordinated approach. This includes partnering with key stakeholders, providing effective communication, and prioritizing high-impact interventions. This article reviews the intersection of planetary health and radiology. Its goals are to emphasize why we should care about sustainability, showcase actions we can take to mitigate our impact, and prepare us to adapt to the effects of climate change. © RSNA, 2024 Supplemental material is available for this article.

Human factors engineering involves the study and development of methods aimed at enhancing performance, improving safety, and optimizing user satisfaction. The focus of human factors engineering encompasses the design of work environments and an understanding of human mental processes to prevent errors. In this review, we summarize the history, applications, and impacts of human factors engineering on the healthcare field. To illustrate these applications and impacts, we provide several examples of how successful integration of a human factors engineer in our pediatric radiology department has positively impacted various projects. The successful integration of human factors engineering expertise has contributed to projects including improving response times for portable radiography requests, deploying COVID-19 response resources, informing the redesign of scheduling workflows, and implementation of a virtual ergonomics program for remote workers. In sum, the integration of human factors engineering insight into our department has resulted in tangible benefits and has also positioned us as proactive contributors to broader hospital-wide improvements.

INTRODUCTION: Hip fracture is a serious affliction that requires fast care and an X-ray examination, which are provided by an ambulance and a visit to the radiology department, respectively. If a well-functioning mobile X-ray service could be developed, by examining the patient in their own home, both the work strain of hospital workers and patient suffering could be reduced. The purpose of this study was to determine if the mobile X-ray service could be a supplement to the fast-track process that is utilised by the ambulance service. The study also examines other department's opinion of this implementation. METHODS: A mixed method was used where data from a Swedish hospital's local RIS/PACS was collected from 706 patients for quantitative analysis, and six personnel working at the hospital were interviewed to obtain qualitative data. RESULTS: The quantitative data demonstrates that the actual mobile X-ray service cannot act in such an acute manner as an ambulance service due to the staffing problems that the hospital is faced with, but with optimal staffing, radiographs with mobile X-ray service could be performed within an acute timeframe. The qualitative data shows that there is a strong wish for the mobile X-ray service to expand and be more active, but this requires a better staffing situation in the radiology department and better communication possibilities between other departments. CONCLUSION: The mobile X-ray service is desirable in the investigated region, and it could benefit both the emergency ward and the ambulance service, and it could function as infection control for geriatric patients, but more radiographers on staff is required if the service should be functional as a complement to the hip-"fast track". More studies on the subject are required. IMPLICATION FOR PRACTICE: A wide generalisation of the results is not applicable in this study, as mobile X-ray and the "hip fast track" is not a widespread service throughout Sweden. This means that this study only suggests trends, which needs to be studied further.

There are approximately 200 academic radiology departments in the United States. While academic medical centers vary widely depending on their size, complexity, medical school affiliation, research portfolio, and geographic location, they are united by their 3 core missions: patient care, education and training, and scholarship. Despite inherent differences, the current challenges faced by all academic radiology departments have common threads; potential solutions and future adaptations will need to be tailored and individualized-one size will not fit all. In this article, we provide an overview based on our experiences at 4 academic centers across the United States, from relatively small to very large size, and discuss creative and innovative ways to adapt, including community expansion, hybrid models of faculty in-person vs teleradiology (traditional vs non-traditional schedule), work-life integration, recruitment and retention, mentorship, among others.

OBJECTIVE: This study aims to develop and evaluate a semi-automated workflow using natural language processing (NLP) for sharing positive patient feedback with radiology staff, assessing its efficiency and impact on radiology staff morale. METHODS: The HIPAA-compliant, institutional review board-waived implementation study was conducted from April 2022 to June 2023 and introduced a Patient Praises program to distribute positive patient feedback to radiology staff collected from patient surveys. The study transitioned from an initial manual workflow to a hybrid process using an NLP model trained on 1,034 annotated comments and validated on 260 holdout reports. The times to generate Patient Praises e-mails were compared between manual and hybrid workflows. Impact of Patient Praises on radiology staff was measured using a four-question Likert scale survey and an open text feedback box. Kruskal-Wallis test and post hoc Dunn's test were performed to evaluate differences in time for different workflows. RESULTS: From April 2022 to June 2023, the radiology department received 10,643 patient surveys. Of those surveys, 95.6% contained positive comments, with 9.6% (n = 978) shared as Patient Praises to staff. After implementation of the hybrid workflow in March 2023, 45.8% of Patient Praises were sent through the hybrid workflow and 54.2% were sent manually. Time efficiency analysis on 30-case subsets revealed that the hybrid workflow without edits was the most efficient, taking a median of 0.7 min per case. A high proportion of staff found the praises made them feel appreciated (94%) and valued (90%) responding with a 5/5 agreement on 5-point Likert scale responses. CONCLUSION: A hybrid workflow incorporating NLP significantly improves time efficiency for the Patient Praises program while increasing feelings of acknowledgment and value among staff.

Protection of patients against hospital-acquired infections is of major importance. Disinfection of magnetic resonance imaging suites is, due to their unique properties and environment particularly, difficult to implement. We developed an OPTI-JET CS MD 2ZE aerosolizator for disinfection of a magnetic resonance imaging suite using the electrolyzed oxidizing water biocide Steriplant©N. The disinfection of the magnetic resonance imaging suite with this system reduced from the number of colony formed unit/m3 air by 87% and 96% in 6 and 15 min of disinfection, respectively. It is well known that exposure of personnel or patients to aerosols may represent risk to the respiratory system; therefore, the aim of this study was to assess potential cytotoxicity and genotoxicity of Steriplant©N aerosolization toward human alveolar cells A459 in vitro. The A459 cells were exposed to aerosol containing different concentrations (50% and 100% v/v) of Steripalnt©N for 6 min in a chamber that had been constructed to simulate the conditions in the magnetic resonance imaging suite. The cytotoxicity was evaluated by measuring iodide uptake, and the genotoxicity was determined by measuring formation of phosphorylated H2AX histones, a marker for deoxyribonucleic acid double-strand breaks, immediately after the aerosolization and after 1, 4, and 24 h postincubation. The results demonstrated that aerosolization with Steriplant©N at conditions reflecting aerosolization in a magnetic resonance imaging suite is not cytotoxic and does not exhibit genotoxic potential in vitro.

The radiology department was categorized as a "high risk area" during the severe acute respiratory syndrome (SARS) outbreak in 2003 and is similarly considered a "high risk area" during the current coronavirus (COVID-19) pandemic. The purpose of infection control is to isolate patients with suspected or confirmed COVID-19 from uninfected people by utilizing separate equipment, spaces, and healthcare workers. Infection control measures should be prioritized to prevent the nosocomial spread of infection. We established a COVID-19 infection control team in our radiology department. The team's responsibilities include triaging patients with confirmed or suspected COVID-19, performing imaging and reporting, using dedicated equipment, disinfecting the equipment and the immediate environment, and staff scheduling.

BACKGROUND: COVID-19 infection is particularly aggressive in frail patients, as cancer patients. Therefore, the more suitable management of the oncological patient requires a multidisciplinary assessment, to identify which patients should be treated, as inpatients or outpatients, and which treatments can be procrastinated. CONCLUSIONS: The role of radiologist is crucial, and, all cancer patients who need an imaging evaluation will need to be studied, using the most appropriate imaging tools related to the clinical question and paying a special attention to preserve public health. Guidelines are necessary in the correct organization of a radiology unit to manage patients with suspected or confirmed COVID-19 infection, and whenever possible, a satellite radiography center with dedicated equipment should be used to decrease the transmission risk.

AIM: To assess, via a survey of UK radiological departments, if the COVID-19 pandemic led to a change in radiological reporting undertaken in a home environment with appropriate IT support. MATERIALS AND METHODS: All imaging departments in the UK were contacted and asked about the provision of home reporting and IT support before and after the first wave of the pandemic. RESULTS: One hundred and thirty-seven of the 217 departments contacted replied, producing a response rate of 61%. There was a 147% increase in the provision of remote access viewing and reporting platforms during the pandemic. Although 578 consultants had access to a viewing platform pre-pandemic, this had increased to 1,431 during the course of the first wave. CONCLUSION: This survey represents work undertaken by UK NHS Trusts in co-ordinating and providing increased home-reporting facilities to UK radiologists during the first wave of this global pandemic. The impact of these facilities has been shown to allow more than just the provision of reporting of both elective and emergency imaging and provides additional flexibility in how UK radiologists can help support and provide services. This is a good start, but there are potential problems that now need to be overcome.

OBJECTIVE: To study the impact of 24/7/365 attending radiologist coverage on the turnaround time (TAT) of trauma and nontrauma cases in an emergency and trauma radiology department. PATIENTS AND METHODS: This was a retrospective chart review in which TAT of patients coming to the emergency department between 2 periods: (1) December 1, 2012, to September 30, 2013, and (2) January 1, 2017, to January 30, 2018, and whose reports were read by an attending emergency and trauma radiologist was noted. RESULTS: The 24/7/365 radiology coverage was associated with a significant reduction in TAT of computed tomography reports, and the time reduction was comparable between trauma and nontrauma cases. In adjusted models, the extension of radiology coverage was associated with an average of 7.83 hours reduction in overall TAT (95% confidence interval [CI]: 7.44-8.22) for reports related to trauma, in which 2.73 hours were due to reduction in completion to transcription time (TC; 95% CI: 2.53-2.93), and 5.10 hours were due to reduction in transcription to finalization time (TF; 95% CI: 4.75-5.44). For reports related to nontrauma cases, 24/7/365 coverage was associated with an average of 6.07 hours reduction in overall TAT (95% CI: 3.54-8.59), 2.91 hours reduction in TC (95% CI: 1.55-4.26), and 3.16 hours reduction in TF (95% CI: 0.90-5.42). CONCLUSION: Our pilot study demonstrates that the implementation of on-site 24/7/365 attending emergency radiology coverage at a tertiary care center was associated with a reduced TAT for trauma and nontrauma patients imaging studies. Although the magnitude and precision of estimates were slightly higher for trauma cases as compared to nontrauma cases. Trauma examinations stand to benefit the most from 24/7/365 attending level radiology coverage.

The coronavirus 2019 (COVID-19) outbreak poses a serious public health risk. To date, the disease has affected almost all countries in the world. The enormous scale of the outbreak and the relative lack of knowledge and information regarding a new virus, as well as the unpredictability of events, make it challenging for leadership teams to respond. This paper shares how we have reconfigured our radiology leadership team into a smaller disease outbreak task force (DOTF) to respond and coordinate all related efforts during this ongoing COVID-19 pandemic. The DOTF format is modelled after the military with domain groups looking at manpower, intelligence, operations, and logistics matters on a daily basis so that timely decisions can be made and action plans executed promptly. In managing the DOTF, discipline, flexibility, and teamwork are key principles, and these are built upon a strong foundation of focus on infection prevention and control, and patient and staff safety as well as staff well-being. The DOTF has positioned us well to confront the many challenges to date. We believe it will also help us navigate the complex issues that will arise with future surges in cases and in formulating strategies to manage exit from the present and future lockdowns. KEY POINTS: • In a pandemic, regular and directed meetings by a smaller leadership core group are required, for prompt decision making and execution of action plans. • The military format, with domain groups to look at manpower, intelligence, operations, and logistics matters, is useful in managing a pandemic. • Discipline, flexibility, and teamwork with strong focus on infection prevention and control, and patient and staff safety as well as staff well-being are key principles for leadership teams managing a pandemic.

INTRODUCTION: Modifications to common radiographic techniques have resulted from the challenges presented by the COVID-19 pandemic. Reports exist regarding the potential benefits of undertaking mobile radiography through side room windows. The aim of this study was to evaluate the impact on image quality and exposure factors when undertaking such examinations. METHODS: A phantom based study was undertaken using a digital X-ray room. Control acquisitions, using a commercially available image quality test tool, were performed using standard mobile chest radiography acquisition factors. Image quality (physical and visual), incidence surface air kerma (ISAK), Exposure Index (EI) and Deviation Index (DI) were recorded. Image quality and radiation dose were further assessed for two additional (experimental) scenarios, where a side room window was located immediately adjacent to the exit port of the light beam diaphragm. The goal of experimental scenario one was to modify exposure factors to maintain the control ISAK. The goal of experimental scenario two was to modify exposure factors to maintain the control EI and DI. Dose and image quality data were compared between the three scenarios. RESULTS: To maintain the pre-window (control) ISAK (76 µGy), tube output needed a three-fold increase (90 kV/4 mAs versus 90 kV/11.25 mAs). To maintain EI/DI a more modest increase in tube output was required (90 kV/8 mAs/ISAK 54 µGy). Physical and visual assessments of spatial resolution and signal-to-noise ratio were indifferent between the three scenarios. There was a slight statistically significant reduction in contrast-to-noise ratio when imaging through the glass window (2.3 versus 1.4 and 1.2; P = 0.005). CONCLUSION: Undertaking mobile X-ray examinations through side room windows is potentially feasible but does require an increase in tube output and is likely to be limited by minor reductions in image quality. IMPLICATIONS FOR PRACTICE: Mobile examinations performed through side room windows should only be used in limited circumstances and future clinical evaluation of this technique is warranted.

INTRODUCTION: With the current Covid-19 pandemic, general wards have been converted into cohort wards for Covid-19 patients who are stable and ambulant. A 2-radiographer mobile radiography team is required to perform bedside Chest X-rays (CXR) for these patients. Hospital guidelines require both radiographers to be in full Personal Protective Equipment (PPE) throughout the image acquisition process and the mobile radiographic unit needs to be disinfected twice after each case. This affects the efficiency of the procedure and an increase usage of limited PPE resources. This study aims to explore the feasibility of performing mobile chest radiography with the mobile radiographic unit in a "clean" zone of the hospital ward. METHODS: An anthropomorphic body phantom was used during the test. With the mobile radiographic unit placed in a "clean" zone, the phantom and the mobile radiographic unit was segregated by the room door with a clear glass panel. The test was carried out with the room door open and closed. Integrated radiation level and patient dose were measured. A consultant radiologist was invited to review and score all the images acquired using a Barco Medical Grade workstation. The Absolute Visual Grading Analysis (VGA) scoring system was used to score these images. RESULTS: A VGA score of 4 was given to all the 40 test images, suggesting that there is no significant differences in the image quality of the images acquired using the 2 different methods. Radiation exposure received by the patient at the highest kV setting through the glass is comparable to the regular CXR on patient without glass panel at 90 kV, suggesting that there is no significant increase in patient dose. CONCLUSION: The result suggests that acquiring CXR with the X-ray beam attenuating through a glass panel is a safe and feasible way of performing CXR for COVID-19 patients in the newly converted COVID wards. This will allow the mobile radiographic unit as well as one radiographer to be completely segregated from the patient. IMPLICATIONS FOR PRACTICE: This new method of acquiring CXR in an isolation facility set up requires a 2-Radiographer mobile radiography team, and is applicable only for patients who are generally well and not presented with any mobility issues. It is also important to note that a clear glass panel must be present in the barriers set up for segregation between the "clean" zone and patient zone in order to use this new method of acquiring CXR.
