    Radiology departmental policy compliance with Swedish guidelines regarding post-contrast acute kidney injury for examinations with iodinated contrast media2021In: Radiography, ISSN 1078-8174, E-ISSN 1532-2831, Vol. 27, no 4, p. 1058-1063Article in journal (Refereed)
    Abstract [en]

    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. (C) 2021 The College of Radiographers.

    Poor reliability and reproducibility of 3 different radiographical classification systems for distal ulna fractures2022In: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 93, p. 438-443Article in journal (Refereed)
    Abstract [en]

    Background and purpose - Classification of fractures can be valuable for research purposes but also in clinical work. Especially with rare fractures, such as distal ulna fractures, a treatment algorithm based on a classification can be helpful. We compared 3 different classification systems of distal ulna fractures and investigated their reliability and reproducibility. Patients and methods - patients with 97 fractures of the distal ulna, excluding the ulnar styloid, were included. All fractures were independently classified by 3 observers according to the classification by Biyani, AO/OTA 2007, and AO/OTA 2018. The classification process was repeated after a minimum of 3 weeks. We used Kappa value analysis to determine inter- and intra-rater agreement.

    Results - The inter-rater agreement of the AO/OTA 2007 classification was judged as fair,. 0.40, whereas the agreement of AO/OTA 2018 and Biyani was moderate at. 0.42 and 0.43 respectively. The intra-rater agreement was judged as moderate for all classifications. Interpretation - The differences between the classifications were small and the overall impression was that neither of them was good enough to be of substantial clinical value. The Biyani classification, being developed specifically for distal ulna fractures, was the easiest and most fitting for the fracture patterns seen in our material, but lacking options for fractures of the distal diaphysis. Standard radiographs were considered insufficient for an accurate classification. A better radiographic method combined with a revised classification might improve accuracy, reliability, and reproducibility.
