Paediatric trauma imaging – how well do we do?
Abstract / Clinical Radiology 69 (2014) S11eS22
S17
Standard, indicator and target: The target was to achieve 100 % compliance to the protocol. Methodology: From November 2013 retrospective data was collected on 100 consecutive patients admitted to Leeds General Infirmary with either isolated head injury or major trauma (when a head trauma CT is mandatory). Results of 1st audit round: Out of 100 patients, 94% had adequate imaging sent to PACS. 4% had 2 mm thickness or greater and 2% had no bony reconstructions. 1st action plan: The data was presented to the on-call Radiographers. Results of 2nd round: Data was collected prospectively from 100 consecutive patients from January 2014 using the same criteria. 94% had 1mm bony reconstructions (or thinner); 1 had 3mm and 5 had no bony reconstructions. 2nd action plan: No improvement was demonstrated. We have now presented our data to the Radiologists to underline the importance of reporting with the appropriate datasets in trauma.
Methodology: A CRIS search was performed identifying 50 consecutive pre-operative CUS between 01/09/12-31/10/13. Clinical requests, saved images and radiologists’ reports were reviewed for indication and compliance with imaging standards. All patients were included. Results of 1st audit round: 84% (standard 100%) of patients had an appropriate indication for CUS. 94% (standard 100%) of scans matched the minimum technical standard. It was also noted that 96% of patients also had a pre-operative renal ultrasound of which only 48% were indicated. 1st action plan: Agreed action plan: 1. Prompt review of local guidelines for pre-operative cranial and renal ultrasound in CHD. 2. Re-distribution of technical imaging standards to radiologists. Re-audit in 1 year after implementation of action plan.

A pain in the neck! Too many normal paediatric cervical spine CTs in trauma?
Authors: Cheng Fang*, Anushka Patchava, Saira Haque Background: Trauma is a leading cause of childhood death. Accurate diagnosis is essential for clinical management. Careful thought must be given prior to exposing children to CT due to significant long term risks. This audit assesses how we image children following major trauma in an emergency setting. Standard, indicator and target: The British Society of Pediatric Radiology imaging protocol for paediatric trauma and NICE guidelines are used as the standards. Plain cervical spine (C-spine) film should be used to exclude bony injury. CT C-spine is only indicted if plain film is abnormal. Thoracic CT is indicated in penetrative chest wall injury or if the chest x-ray shows significant injury. CT abdomen is only indicated if the mechanism of injury is significant or there are clinical concerns such as abdominal tenderness/ distension, bleeding and hypovolaemia. Methodology: Primary imaging requests including CT head, C-spine films, CT C-spine and CT chest, abdomen were audited against the standards in all paediatric traumas (age 0-16 years) for 6 months. Results of 1st audit round: 90 cases were reviewed. All CT head requests were justified. CT C-spines were performed in 5 patients despite normal plain films, which were all normal. 4 of 5 of CT chest requests followed BSPR guidelines. 10 of 11 CT abdomen followed guidelines. 1st action plan: We will raise awareness of a child specific approach to assess paediatric trauma in an emergency setting through regular teaching. Visual aid of paediatric imaging pathways will be made available. Audit of pre-operative cranial ultrasound in congenital heart disease Authors: Andrew Macallister*, David Grier Background: Cranial ultrasound (CUS) is a quick, non-invasive imaging technique used to assess the infant brain. There is a clear technical standard for minimum imaging requirements. It is commonly used in the pre-operative assessment of congenital heart disease (CHD). Certain CHDs are commonly associated with structural or pathological brain abnormalities. Standard, indicator and target: CUS had not previously been audited in our department. We aimed to assess practice against national and local guidelines. 1.100% of pre-operative CUS in CHD should have an indication from the Bristol Royal Children’s Hospital guidelines (local), 2.100% of scans should have at least 5 sagittal and 6 coronal images saved to PACS (National).

Background: CT cervical spines contribute approximately 60x higher dosage to the thyroid than x-rays. NICE guidelines (1) state CT should be reserved where radiographs are inadequate, abnormal, in presence of severe head/multi-region trauma or neurological deficit. Previous local audits demonstrated no abnormal CTs in 1996-7 and 1 in 2002-2003 demonstrating rotatory atlanto- axial subluxation, which was also visible on plain radiography. Are we increasing the number of nonindicated paediatric CTs? Standard, indicator and target: 100% of patients should meet NICE guidelines. Methodology: All CT cervical spines of patients aged <18 years were reviewed. Preceding radiograph findings and indications for CT were analysed. Results of 1st audit round: May 2008 - June 2012 (49 months), 52 CTs performed. 26 (50%) cases met imaging guidelines. 1 abnormality (18 year old motorcycle accident with C7 fractures). 1st action plan: Results presented at local governance meeting with review of diagnostic pitfalls and demonstration of optimal radiographic technique. Commitment to CT reduction was agreed. Results of 2nd round: July 2012 - April 2014 (21 months), 13 CTs performed (8 localized scans to site of pain). 9 (69%) cases met guidelines for imaging. All CTs normal. 50% reduction in CT use. 2nd action plan: Guaranteed next day paediatric MRI cervical spine service in presence of normal plain radiograph instead of CT planned. A reduction in CT can be effected. Practical guidance for DGHs is required, particularly for those outsourcing out of hours work. Knowledge of radiation exposure in common examinations amongst radiology department staff

Authors: Ai-Lee Chang*, Sophie Wood, Dorothy Keane Background: Ionising radiation (Medical Exposure) regulations 2000 and 2006 (IR(ME)R) impose a responsibility on imaging departments to ensure that all exposures to ionising radiation are justified and doses are optimised. Standard, indicator and target: All radiology department staff should have knowledge of relevant radiation doses for commonly performed examinations. 50% awareness of dose estimation per chest x-ray equivalent. Methodology: Questionnaire with 14 questions. Results of 1st audit round: November 2012 Responders 54/70(77%)
