Rapid access imaging for occult fractured neck of femur

Summary We completed a full audit cycle to assess waiting times for inpatients with suspected occult femoral neck fracture to get MRI scan, identify the causes of delay and implement the changes to reduce the waiting times. We have proved that inpatient MRI waiting times can significantly be reduced by a targeted approach. Introduction The timely management of hip fractures is now underpinned by NICE Guidance, June 2011. This includes a statement that magnetic resonance imaging (MRI) should be offered if occult femoral neck fracture is suspected and that MRI should be made available within 24 hours. We completed a full audit cycle: (1) analyse the time taken for inpatient MRI to be performed for suspected occult femoral neck fractures, (2) identify correctable reasons for delay, (3) develop and implement changes and (4) re-audit. Methods Data was collected from the computerised radiology information system on consecutive patients between 01/04/2010 and 31/03/2012. This data was presented at a number of directorate audit meetings. Following the development and implementation of targeted improvements, a prospective re-audit was carried out between 01/08/2012 and 31/07/2013. Results After the initial audit, various reasons of delay were identified. The correctable causes for delay were (1) duty radiologist not directly contacted by clinician to request urgent scan, (2) slow vetting and protocoling of electronic requests, (3) resistance to weekend scanning and (4) delay in completing MRI safety questionnaire. After implementing strategies to address these remediable causes of delay, the re-audit demonstrated a 16 % improvement in patients scanned within 24 h. The mean waiting time to get an MRI was 2,025.4 min (SD 2,406.4) for the baseline audit and 1,374 min (SD 1,635.7) for the re-audit. Mean difference is 651.4 min (95 % CI 85.21, 1,217.5; p = 0.0243). Conclusion MRI is a useful and sensitive tool to investigate occult femoral neck fracture. Inpatient MRI waiting times can significantly be reduced by a targeted approach which embodies improved team working.
