Effect of a new computed tomographic image transfer system on management of referrals to a regional neurosurgical service.

Abstract

A computed tomographic image transfer system ('Image Link') was used to link scanners within the Oxford region, UK, to the regional neurosurgical service. 100 consecutive neurosurgical referrals were examined by this system; 43% of the emergency referrals did not require transfer, 31% were transferred electively, and 26% urgently. Most of the patients defined as potentially hazardous for transfer (10/11) did not require neurosurgical intervention. The delay by the use of the system was negligible and early detection of intracranial haematoma contributed to good outcome in some head injured patients. Overall, 3,170 miles of ambulance journey were avoided. Use of image link has led to substantial improvements in management of neurosurgical emergency referrals, cost-effectiveness of neurosurgical and ambulance facilities, and interhospital communication between doctors.
