Immobilisation in Australian paediatric medical imaging: A pilot study

Abstract

AimsThe primary aim of this study is to document the use of paediatric immobilisation techniques in medical imaging. Secondary aims are to investigate differences between current practice of paediatric and non-paediatric facilities and radiographer gender and to investigate immobilisation protocols. MethodsA SurveyMonkey link was distributed through the Australian Society of Medical Imaging and Radiation Therapy (ASMIRT) newsletter. Radiographer members of ASMIRT were invited to participate. Frequency percentage analysis was undertaken; as the 'frequency of immobilisation' response was on a Likert scale and the ages categorical, a Fisher's exact test could determine dependency. ResultsThe use of paediatric immobilisation techniques was determined to be related to age. The most commonly used technique in general X-ray was “other people”; in computed tomography, Velcro, verbal reminders and distraction techniques; and in magnetic resonance imaging, sedation and Velcro. A comparison of immobilisation techniques demonstrated that Velcro use in X-ray was dependent on facility (p = 0.017) with paediatric facilities using it up to 17 years. Immobilisation frequency was dependent in 13–17 years (p = 0.035) with paediatric facilities rarely immobilising and non-paediatric facilities never. No dependencies resulted upon comparing genders. Immobilisation frequency was not dependent between protocols or current practice. ConclusionThe use of paediatric immobilisation technique is related to age with “other people”, sedation, Velcro, verbal reminders and distraction techniques being regularly used. The dependency of Velcro use and immobilisation frequency in 13–17 years is for unknown reasons and further investigation is required. A larger study should be carried out to validate these findings.
