Covid-19 infection in cancer patients: the management in a diagnostic unit.

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.

Initial data from an experiment to implement a safe procedure to perform PA erect chest radiographs for COVID-19 patients with a mobile radiographic system in a "clean" zone of the hospital ward.

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.

Managing patient flows in radiation oncology during the COVID-19 pandemic : Reworking existing treatment designs to prevent infections at a German hot spot area University Hospital.

PURPOSE: The described work aimed to avoid cancellations of indispensable treatments by implementing active patient flow management practices and optimizing infrastructure utilization in the radiation oncology department of a large university hospital and regional COVID-19 treatment center close to the first German SARS-CoV­2 hotspot region Heinsberg in order to prevent nosocomial infections in patients and personnel during the pandemic. PATIENTS AND METHODS: The study comprised year-to-date intervention analyses of in- and outpatient key procedures, machine occupancy, and no-show rates in calendar weeks 12 to 19 of 2019 and 2020 to evaluate effects of active patient flow management while monitoring nosocomial COVID-19 infections. RESULTS: Active patient flow management helped to maintain first-visit appointment compliance above 85.5%. A slight appointment reduction of 10.3% daily (p = 0.004) could still significantly increase downstream planning CT scheduling (p = 0.00001) and performance (p = 0.0001), resulting in an absolute 20.1% (p = 0.009) increment of CT performance while avoiding overbooking practices. Daily treatment start was significantly increased by an absolute value of 18.5% (p = 0.026). Hypofractionation and acceleration were significantly increased (p = 0.0043). Integrating strict testing guidelines, a distancing regimen for staff and patients, hygiene regulations, and precise appointment scheduling, no SARS-CoV­2 infection in 164 tested radiation oncology service inpatients was observed. CONCLUSION: In times of reduced medical infrastructure capacities and resources, controlling infrastructural time per patient as well as optimizing facility utilization and personnel workload during treatment evaluation, planning, and irradiation can help to improve appointment compliance and quality management. Avoiding recurrent and preventable exposure to healthcare infrastructure has potential health benefits and might avert cross infections during the pandemic. Active patient flow management in high-risk COVID-19 regions can help Radiation Oncologists to continue and initiate treatments safely, instead of cancelling and deferring indicated therapies.

How we provided appropriate breast imaging practices in the epicentre of the COVID-19 outbreak in Italy.

Italy has one of the highest COVID-19 clinical burdens in the world and Lombardy region accounts for more than half of the deaths of the country. Since COVID-19 is a novel disease, early impactful decisions are often based on experience of referral centres.We report the re-organisation which our institute (IEO, European Institute of Oncology), a cancer referral centre in Lombardy, went through to make our breast-imaging division pandemic-proof. Using personal-protective-equipment and innovative protocols, we provided essential breast-imaging procedures during COVID-19 pandemic without compromising cancer outcomes.The emergency management and infection-control-measures implemented in our division protected both the patients and the staff, making this experience useful for other radiology departments dealing with the pandemic.

Therapeutic Radiographers at the Helm: Moving Towards Radiographer-Led MR-Guided Radiotherapy.

INTRODUCTION: Magnetic resonance-guided adaptive radiotherapy (MRgART) has the potential to improve treatment processes and outcomes for a variety of tumour sites; however, it requires significant clinical resources. Magnetic resonance linear accelerator (MR-linac) treatments require a daily multidisciplinary presence for delivery. To facilitate sustainable MRgART models, agreed protocols facilitating therapeutic radiographer (RTT)-led delivery must be developed to establish a service similar to conventional image-guided radiotherapy (IGRT). This work provides a clinical perspective on the implementation of a protocol-driven 'clinician-lite' MRgART workflow at one institution. METHODS: To identify knowledge, skills, and competence required at each step in the MRgART workflow, an interdisciplinary informal survey and needs assessment were undertaken to identify additional or enhanced skills required for MRgART, over and above those required for conventional cone-beam computed tomography-based IGRT. The MRgART pathway was critically evaluated by relevant professionals to encourage multidisciplinary input and discussion, allowing an iterative development of the RTT-led workflow. Starting with the simplest online adaptation strategy, consisting of a virtual couch shift and online replanning, clear guidelines were established for the delivery of radical prostate radiotherapy with a reduction in staff numbers present. RESULTS: The MRgART-specific skills identified included MRI safety and screening, MR image acquisition, MRI-based anatomy, multimodality image interpretation and registration, and treatment plan evaluation. These skills were developed in RTTs via tutorials, workshops, focussed self-directed reading, teaching of colleagues, and end-to-end workflow testing. After initial treatments and discussions, roles and responsibilities of the three professional groups (clinicians, RTTs, and physicists) have evolved to achieve a 'clinician-lite' workflow for simple radical prostate treatments. DISCUSSION: Through applying a definitive framework and establishing agreed threshold and action levels for action within anticipated treatment scenarios similar to those in cone-beam computed tomography-based IGRT, we have implemented a 'clinician-lite' workflow for simple adaptive treatments on the MR-linac. The responsibility for online plan evaluation and approval now rests with physicists and RTTs to streamline MRgART. Early evaluation of the framework after treatment of 10 patients has required minimal online clinician input (1.5% of 200 fractions delivered). CONCLUSION: A 'clinician-lite' prostate treatment workflow has been successfully introduced on the MR-linac at our institution and will serve as a model for other tumour sites, using more complex adaptive strategies. Early indications are that this framework has the potential to improve patient throughput and efficiency. Further identification and validation of roles and responsibilities such as online contouring, and more interactive online planning, will facilitate RTTs to fully lead in the online workflow as adaptive radiotherapy becomes ever more complex.

Technique, radiation safety and image quality for chest X-ray imaging through glass and in mobile settings during the COVID-19 pandemic.

The COVID-19 pandemic in 2020 has led to preparations within our hospital for an expected surge of patients. This included developing a technique to perform mobile chest X-ray imaging through glass, allowing the X-ray unit to remain outside of the patient's room, effectively reducing the cleaning time associated with disinfecting equipment. The technique also reduced the infection risk of radiographers. We assessed the attenuation of different types of glass in the hospital and the technique parameters required to account for the glass filtration and additional source to image distance (SID). Radiation measurements were undertaken in a simulated set-up to determine the appropriate position for staff inside and outside the room to ensure occupational doses were kept as low as reasonably achievable. Image quality was scored and technical parameter information collated. The alternative to imaging through glass is the standard portable chest X-ray within the room. The radiation safety requirements for this standard technique were also assessed. Image quality was found to be acceptable or borderline in 90% of the images taken through glass and the average patient dose was 0.02 millisieverts (mSv) per image. The majority (67%) of images were acquired at 110 kV, with an average 5.5 mAs and with SID ranging from 180 to 300 cm. With staff positioned at greater than 1 m from the patient and at more than 1 m laterally from the tube head outside the room to minimise scatter exposure, air kerma values did not exceed 0.5 microgray (µGy) per image. This method has been implemented successfully.

Policies and Guidelines for COVID-19 Preparedness: Experiences from the University of Washington.

The coronavirus disease 2019 (COVID-19) pandemic initially manifested in the United States in the greater Seattle area and has rapidly progressed across the nation in the past 2 months, with the United States having the highest number of cases in the world. Radiology departments play a critical role in policy and guideline development both for the department and for the institutions, specifically in planning diagnostic screening, triage, and management of patients. In addition, radiology workflows, volumes, and access must be optimized in preparation for the expected surges in the number of patients with COVID-19. In this article, the authors discuss the processes that have been implemented at the University of Washington in managing the COVID-19 pandemic as well in preparing for patient surges, which may provide important guidance for other radiology departments who are in the early stages of preparation and management.

Radiation Therapy During the COVID-19 Pandemic: Experience from Beijing, China.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is now a global pandemic. It is unclear to radiotherapy practitioners how to carry out radiotherapy during the epidemic. PATIENTS AND METHODS: After the outbreak of COVID-19, our Institute established measures for the prevention and control of COVID-19, and continues to treat patients according to these measures. The Radiotherapy Department has been divided into a clean zone and a semi-contaminated zone, and corresponding personal protective equipment is used in these zones. The temperature of patients and their escorts, and history of fever are assessed daily. Special procedures are performed during radiotherapy setup and intracavitary brachytherapy. RESULTS: Over a period of 2 months, 655 patients were treated in the Department. Sixteen patients with fever were identified and no patient undergoing radiotherapy or medical staff have been infected with COVID-19. CONCLUSION: Our protective measures were found to be effective and can be used as a reference in places where COVID-19 situations are not markedly serious.

COVID-19 in the radiology department: What radiographers need to know.

OBJECTIVES: The aim is to review current literature related to the diagnosis, management, and follow-up of suspected and confirmed Covid-19 cases. KEY FINDINGS: Medical Imaging plays an important auxiliary role in the diagnosis of Covid-19 patients, mainly those most seriously affected. Practice differs widely among different countries, mainly due to the variability of access to resources (viral testing and imaging equipment, specialised staff, protective equipment). It has been now well-documented that chest radiographs should be the first-line imaging tool and chest CT should only be reserved for critically ill patients, or when chest radiograph and clinical presentation may be inconclusive. CONCLUSION: As radiographers work on the frontline, they should be aware of the potential risks associated with Covid-19 and engage in optimal strategies to reduce these. Their role in vetting, conducting and often reporting the imaging examinations is vital, as well as their contribution in patient safety and care. Medical Imaging should be limited to critically ill patients, and where it may have an impact on the patient management plan. IMPLICATIONS FOR PRACTICE: At the time of publication, this review offers the most up-to-date recommendations for clinical practitioners in radiology departments, including radiographers. Radiography practice has to significantly adjust to these new requirements to support optimal and safe imaging practices for the diagnosis of Covid-19. The adoption of low dose CT, rigorous infection control protocols and optimal use of personal protective equipment may reduce the potential risks of radiation exposure and infection, respectively, within Radiology departments.

Radiotherapy during COVID-19 pandemic. How to create a No fly zone: a Northern Italy experience.

BACKGROUND: SARS-CoV-2 pandemic represents a troubling health emergency but also a main challenge for the clinical governance of the system. Discontinuation of radiation treatments is not desirable and potentially life-threatening. On the other hand, accesses to hospital expose cancer patients to an increased risk of COVID-19 infection. We report our extended protocol, draft to manage clinical activities in our radiotherapy department, by minimizing contagion risks. METHODS: We used telephonic screening to assess the need for patient admission. A telephonic triage was performed to identify the presence of COVID-19 infection risk factors or symptoms. New treatments were stratified according to priority codes. A reserved entrance to radiotherapy department was assured for patients and staff. Surgical disposable mask was required for patients and caregivers. The activities were distributed during the whole workday, avoiding overlap to reduce aggregation. RESULTS: From 1st February 2020 to 31 March 2020, we reported an increase in the number of first medical examinations and treatments, compared to the same period of the previous year. Outpatients first medical examinations have been spread over the 12 working hours. No COVID-19 cases were detected. CONCLUSION: During COVID-19 pandemic, we introduced procedures that allowed us to ensure the continuity in oncological cares, with limited risks of infection for patients and staff.

How to work together between nuclear medicine and radiotherapy departments?

Among the available imaging techniques, functional imaging provided by nuclear medicine departments represents a tool of choice for the oncoradiotherapist for targeting tumour activity, with positron emission tomography as the main modality. Before, during or after radiotherapy, functional imaging helps guide the oncoradiotherapist in making decisions and in the strategic choice of pathology management. Setting up a working group to ensure perfect coordination at all levels is the first step. Key points for a common and coordinated management between the two departments are the definition of an organizational logistic, training of personnel at every levels, standardization of nomenclatures, the choice of adapted and common equipment, implementation of regulatory controls, and research/clinical routine continuum. The availability of functional examinations dedicated to radiotherapy in clinical routine is possible and requires a convergence of teams and a pooling of tools and techniques.

Reducing Errors in Radiology Specimen Labeling Through Use of a Two-person Check.

Improper specimen labeling of biopsy samples can cause substantial harm to patients through diagnostic delays, administration of inappropriate treatments, and can result in a loss of trust in the healthcare system. Specimen labeling errors are considered a relevant safety metric in our department and tracked on a rolling basis. One imaging section was noted to have nearly completely eliminated these errors through implementation of a 2-person check prior to submission to pathology. The purpose of this intervention was to identify the causes of continued specimen labeling errors in radiology and to standardize the specimen labeling workflow across the department of radiology to include the best practice identified in breast imaging utilizing a 2-person check. Preintervention, 31 specimen labeling errors were reported by the procedural staff over a period of 149 weeks resulting in an error rate of 0.21 errors per week. Postintervention, 3 specimen labeling errors occurred in the next 46 weeks resulting in a rate of 0.07 errors per week, a 68.8% decrease in the specimen labeling error rate. This quality improvement project highlights the process flaws which contribute to medical errors and demonstrates a potential pathway to try and reduce these errors and patient harm without significant investment in capital or new technology.

Turning around cancer: Oncology imaging and implications for emergency department radiology workflow.

PURPOSE: Oncologic imaging in the emergency department (ED) is frequently encountered, including non-acute scans known as "metastatic workups" or "staging" (referred to as "cancer staging computed tomography (CT) exams"). This study examines the impact of oncologic staging CT exams on ED imaging turnaround time (TAT), defined as the time from the end of the CT exam to a final signed radiologist report, as well as order to scan completion time. METHODS: A retrospective review was conducted of all adult patients presenting to an urban, quaternary academic medical center ED from February 2016 to September 2017, who had CT imaging ordered, performed, and interpreted in the ED imaging department. CT exams containing institution-specific cancer descriptors were included. After excluding all acute exams, cancer staging CT exams were compared to a matched cohort of non-oncologic ED CT exams to evaluate median TAT and order to scan completion time using a log transformed multivariable linear regression. RESULTS: Adjusting for age and CT body part, cancer staging CT exams were associated with an independently statistically significant increased median log TAT compared to non-oncologic ED CT exams (114.5 min [IQR 112] versus 69 min [IQR 67], respectively, p < .0001) and an independently statistically significant increased median log initial order to scan completion time (166 min [IQR: 89] vs 119 min [IQR: 93], p < .0001). CONCLUSION: Oncology patients receiving non-acute metastatic workup scans in the ED have a significantly longer TAT compared to non-oncologic ED CT exams as well as longer order to scan completion times.

Quality and safety innovations in the Radiology Department during the COVID-19 pandemic: a Latin American experience / Inovações de qualidade e segurança no Departamento de Radiologia durante a pandemia pela COVID-19: uma experiência Latino-Americano

Change management for radiation therapists - transitioning to the new Royal Adelaide Hospital.

One of the largest change operations to take place in South Australia was the moving of the Royal Adelaide Hospital (RAH) to its new site in 2017. Change can influence workplace effectiveness and staff satisfaction and morale. Understanding the stages of change, staff experience and carefully managing the process is important. This paper aims to describe the successful move of the radiation therapy department at the RAH to its new site, focusing on the staff experience and management strategies to ensure the success of the move. A four-stage model of change was used to guide understand, manage and reflect upon the transition of the RAH radiation therapy department to a new site. Key change events and management strategies are described and aligned with the four stages of change. The move to the new site was a great success with a transition period working across two sites enabling a slower ramp up of activity at the new site supporting staff and patients in adjusting to the new environment. The four-stage model of change assisted in the smooth implementation of a transition plan for radiation oncology. At the RAH, innovation and development are encouraged, along with management having a comprehensive understanding of organisational change enabling the radiation oncology department to successfully navigate rapid change.

Overcoming Human Barriers to Safety Event Reporting in Radiology.

In high-reliability industries that are dedicated to ensuring safety, safety event reporting is the cornerstone of improvement. However, human factors can interfere with consistent reporting. Common human factors that are barriers to safety event reporting include liability concerns; time constraints; physician autonomy; self-regulation; collegiality; the lack of listening, language training, and/or feedback regarding reported events; unclear responsibilities within safety teams; and a high reporting threshold. Other barriers include fears of challenging authority, being disrespected, retribution, and the creation of a difficult work environment. These factors are reviewed in the health care setting, and the countermeasures that need to be introduced at the frontline employee, leadership employee (physicians and managers), and departmental and organizational levels to create a culture of safety in which all employees feel comfortable raising safety concerns are discussed. ©RSNA, 2019.

A New and Inclusive Intake Form for Diagnostic Imaging Departments.

INTRODUCTION: The gender landscape is changing. For professionals in health care, particularly diagnostic imaging (DI), we need better communication tools to obtain personal information from this gender diverse community. We need more specific information from patients because we are performing examinations in which radiation is involved. It is our professional duty to protect a patient's reproductive organs whenever possible, but we must know where those organs are located. In addition, we must determine if a patient could be pregnant or not. Compliance to the professional duty must also extend to transgender and nonbinary patients. Transgender patients do not express or identify the same as their sex assigned at birth; therefore, we may shield inappropriately and expose their reproductive organs unintentionally. Nonbinary patients do not identify as either male or female, and therefore, their expression does not indicate reproductive organ location. METHOD: There are currently no specific forms in DI that ask the questions we need to know to protect the public from unnecessary radiation exposure to reproductive organs. In developing the new form, we began looking at current practices in DI departments to better understand where the communication gap was and what important information would be required in the new form. RESULT: The authors have created a new intake form that accommodates all patients-regardless of age or gender. The result is the SIGE (Sex, Identity, Gender, Expression) form. DISSCUSSION: The SIGE form is inclusive and asks the necessary questions medical radiation technologists need to know in a respectful and professional manner so that we can shield gonadal tissue from ionizing radiation. In addition, the intention of the form is to help the gender diverse community to feel safe and respected in our department.

[Implementation of innovations in healthcare: radiotherapy as an example]. / Implementatie van innovaties in de zorg.

The implementation of innovations is considered necessary in healthcare, both for improving patient outcomes and services and to reduce costs. Two problems can occur during the implementation process: innovations that have not been properly evaluated in terms of patient outcomes or cost-effectiveness can sometimes spread quickly, whereas innovations that have shown to lead to significant improvements in a research study setting may struggle to find their way into clinical practice. Problems may also arise when organizational innovations are implemented that are not evidence-based: an example would be the implementation of a new ICT system that affects the patient's environment negatively upon introduction. In this article, the problems surrounding innovation implementation in medical care are described in general and in more concrete terms, we describe how Dutch radiotherapy centres perform in this area. Based on the findings, a systematic plan is described that can help to innovate more effectively and efficiently to the benefit of clinical practice in all disciplines.
