AN ON-SITE, EASILY ACCESSIBLE MRI SCANNER IS AN ESSENTIAL REQUIREMENT FOR ANY HOSPITAL PROVIDING ACUTE TRAUMA FACILITIES

Abstract

Purpose of study: This study assessed the current availability of “out of hours” MRI scans for patients who present with symptoms suggestive of cauda equina syndrome to trauma units across the United Kingdom (UK).

Methods: 98 trauma units in 212 hospitals across the UK were identified. Senior house officers and registrars were questioned about the availability of emergency MRI scans after 5pm and midnight and at weekends. All units responded to the survey.

Results: 88 of 98 units had an on-site MRI scanner. In 32 hospitals, an MRI scan could be obtained after 5pm. In only 27 hospitals was this possible after midnight. In 58 units (65%) of cases, consultant to consultant contact was required to arrange the scan. 67 units found it “very difficult” or “impossible” to obtain an MRI scan at the weekend producing a potential delay of 64 hours from presentation at 5pm on a Friday night to 9am on a Monday morning.

Conclusions: The availability of urgent MRI scans in cases of suspected cauda equina syndrome currently represents a “postcode lottery” across the UK. This may mean that patients requiring urgent surgical decompression face a significant delay in diagnosis. Delayed or missed cases of cauda equina syndrome have huge personal, social and economic impact. On-site MRI facilities, which are available 24 hours a day for such cases are recommended in all units receiving an acute trauma on call.
