752 Routine In-Hospital Radiographs Following Anterior Cervical Discectomy and Fusion Surgery: Neither Necessary nor Cost-Effective?

Abstract

Abstract Aim To evaluate whether a post-operative radiograph of the cervical spine before discharge is either clinically justified or cost-effective in patients who have undergone an ACDF, despite having satisfactory intra-operative imaging. Method A retrospective review of 101 ACDF patients from a single neurosurgical centre. 78 had an in-hospital post-operative radiograph, 23 did not. In 95 of these, it was documented that there was ‘satisfactory intra-operative imaging’. All patients had intra-operative imaging of completed instrumentation. Any post-operative complications were noted, and the length of hospital stay (LOS) recorded. Study parameters also included: levels operated on, whether or not a plate was used with a cage, additional costings to the hospital. Results There was one post-operative complication relating to the metalwork in the 101 patients. However, the decision to perform this x-ray was based purely on the deteriorating post-operative clinical picture. In the cohort that had POXR’s, the average length of stay was 66.7 hours. Without POXR, it was 21 hours. The additional cost to the trust of performing the in-hospital radiographs was calculated to be £71,523 per year. Conclusions In patients who undergo ACDF surgery with an uneventful post-operative course and satisfactory intra-operative imaging, in-hospital post-operative radiographs serve no clinical purpose and delay discharge. This gives additional cost to the trust, unnecessary radiation exposure and occupies potential bedspace.
