Analysis of a neurosurgical directed acute spinal cord compression pathway at Michigan Medicine, a tertiary referral hospital.

e18285 Background: Spinal cord compression (SCC) is considered an oncologic emergency that is likely to severely impair patients’ quality of life if immediate action is not taken. Clinicians need a high suspicion to diagnose SCC, as the presenting symptoms are variable and nonspecific. To expedite the diagnosis and treatment of SCC, we instituted an emergent spine MRI imaging pathway that was led by the neurosurgeons and involved close collaboration with medical oncology and radiation oncology. Methods: The charts of all patients from July 2015 to June 2018 who underwent the “MR Spine Cord Compression Acute” imaging pathway at Michigan Medicine were reviewed. Electronic time stamps provided the time of the initial order, the time to scan completion, the time to scan reading, and the time to definitive intervention. The charts were reviewed for the initial neurosurgical physical exam, a presentation consistent with recent trauma, a previous diagnosis of malignancy, and a previous diagnosis of bone metastases. The type and timing of therapy, and survival following the imaging protocol were assessed. Results: 319 unique MRI exams were done over the three-year span, 155 of the patients had cancer, and 75 patients had SCC. The time from ordering of exam to performance is 2.91 hours (0 to 25.45), from performance to read 8.31 hours (0 to 75.25 hours). Time from MRI to intervention was 63.14 hours (0 to 432 hours) based on complex decision making around surgical vs. radiation vs. medical therapy. For the majority of patients who were diagnosed with SCC, the cause was secondary to tumor growth from contiguous spinal metastasis, and most had previously identified bone metastases. Degenerative disc extrusion was the most common cause of benign SCC. Conclusions: A neurosurgical directed standard imaging protocol is effective at rapidly diagnosing SCC. Malignant SCC is predominately treated surgically, but complex multi-disciplinary patient centered decision-making involving neurosurgery, radiation oncology, and medical oncology is frequently necessary to arrive at the appropriate treatment.
