Radiographers' confidence in handling iodine based contrast media hypersensitivity reactions.

INTRODUCTION: Adverse reactions to iodinated contrast media, which is used during computed tomography (CT) examinations, are rare. As a result, radiographers have limited experience handling those situations and may feel uncertainty and a lack of confidence. The aim of this study was to investigate radiographers' confidence in handling hypersensitivity reactions to contrast media during CT examinations. METHODS: A survey in the form of a questionnaire was conducted to gather both quantitative and qualitative data. There were 31 clinics that participated in this study, of which four were university hospitals, 17 were medium-sized hospitals and 10 were small hospitals. In total, the questionnaires were distributed to 700 radiographers. The questionnaire contained 12 questions and was distributed via email with a link to the questionnaire. RESULTS: Two hundred-ninety radiographers participated in the survey. 72% of the respondents answered in the middle of the four-point scale (2-3) in response to the statement "I feel confident in handling hypersensitivity reactions". 65% answered that they did not have routines for training regularly regarding hypersensitivity reactions. Qualitative data showed that many of the respondents wished to receive education and training regularly. CONCLUSIONS: The confidence of radiographers regarding the management of hypersensitivity reactions was deficient and most of the respondents wished they felt more confident. IMPLICATION FOR PRACTICE: To increase radiographers' confidence in handling hypersensitivity reactions, it is recommended that the radiology clinics review their routines and the possibility to implement regular training.

Radiology departmental policy compliance with Swedish guidelines regarding post-contrast acute kidney injury for examinations with iodinated contrast media.

INTRODUCTION: Guidelines concerning intravenous iodinated contrast media (CM) during computed tomography (CT) examinations are important to follow to minimize the risk for post-contrast acute kidney injury (PC-AKI). The purpose of this study was to investigate the radiology departmental policy compliance with Swedish guidelines concerning PC-AKI. METHODS: In February 2020, an electronic survey was distributed to the responsible radiographer at 41 radiology departments in all university hospitals and medium-sized hospitals in Sweden. The questions focused on routines around renal functional tests, individualized contrast administration and handling of patients with diabetes mellitus taking metformin. RESULTS: The response rate was 83%. Seventy-six percent (n = 26) of radiology departments calculated estimated glomerular filtration rate (eGFR) from serum creatinine prior to CM administration, but only 24% (n = 8) followed the recommendation to calculate eGFR from both serum creatinine and cystatin C. For acute/inpatients, 55% (n = 18) followed the recommendation that renal functional tests should be performed within 12 h before CM administration. For elective patients, 97% (n = 33) followed the recommendation to have eGFR newer than three months which is acceptable for patients with no history of disease that may have affected renal function. Approximately 80% of the radiology departments followed the recommendation that CM dose always should be individually adjusted to patient eGFR. Seventy-six percent (n = 26) followed the recommendation to continue with metformin at eGFR ≥ 45 ml/min. CONCLUSION: Compliance with the national guidelines was high regarding routines around renal functional tests, dose adjustment of CM and metformin discontinuation. Improvements can be made in using both cystatin C and serum creatinine for eGFR calculations as well as ensuring renal function tests within 12 h for acute/inpatients with acute disease that may affect renal function. IMPLICATIONS FOR PRACTICE: This study raises awareness of the importance of adhering to guidelines in healthcare. To have knowledge about the current level of compliance regarding PCI-AKI is important to maintain and develop effective clinical implementation of guidelines. The variation in practice seen in this study emphasizes the need of more effective implementation strategies to ensure adherence with best practice.

Radiographers' perception on task shifting to nurses and assistant nurses within the radiography profession.

INTRODUCTION: The radiography profession is challenged by greater responsibilities and shortage of educated radiographers. Implementation of task shifting is one strategy to deal with the current situation in health care. The aim of this studiy was to evaluate radiographers' perception of assistant nurses and nurses carrying out tasks that traditionally were undertaken within the radiography profession in a Swedish context. METHODS: An electronic questionnaire was distributed to radiographers at eleven hospitals in Sweden. The questionnaire included background questions and questions about radiographers' perception about task shifting to nurses and assistant nurses. The respondents rated their agreement level regarding task shifting on a five-point Likert scale. Data was statistically evaluated in SPSS using Mann Whitney U test. RESULTS: Sixty-five radiographers participated in the study. Most radiographers responded negatively to task shifting to nurses (72%) or assistant nurses (65%). Most radiographers disagree that nurses should perform mammography screening or work within interventional radiography, while the attitude towards nurses calculating glomerular filtration rate was more positive. A majority disagree regarding assistant nurses performing conventional radiographs, informing the patient about contrast media administration or inserting peripheral intravenous catheters, while there was a positive attitude towards assistant nurses preparing patients for examinations. The attitude towards task shifting was not influenced by age, however radiographers with less working experience were more positive to task shifting in general. CONCLUSION: A majority of the radiographers had a negative attitude towards task shifting to nurses and assistant nurses. The radiographers were more positive to hand over tasks related to patient care and administrative tasks than technical related tasks within the profession. IMPLICATIONS FOR PRACTICE: Knowledge about radiographers' perception on task shifting within the profession is essential when planning and implementing strategies for task shifting in the clinical settings.

Shear wave elastography plaque characterization with mechanical testing validation: a phantom study.

Determining plaque vulnerability is critical when selecting the most suitable treatment for patients with atherosclerotic plaque. Currently, clinical non-invasive ultrasound-based methods for plaque characterization are limited to visual assessment of plaque morphology and new quantitative methods are needed. In this study, shear wave elastography (SWE) was used to characterize hard and soft plaque mimicking inclusions in six common carotid artery phantoms by using phase velocity analysis in static and dynamic environments. The results were validated with mechanical tensile testing. In the static environment, SWE measured a mean shear modulus of 5.8 ± 0.3 kPa and 106.2 ± 17.2 kPa versus 3.3 ± 0.5 Pa and 98.3 ± 3.4 kPa measured by mechanical testing in the soft and hard plaques respectively. Furthermore, it was possible to measure the plaques' shear moduli throughout a simulated cardiac cycle. The results show good agreement between SWE and mechanical testing and indicate the possibility for in vivo arterial plaque characterization using SWE.
