title: Safety and resource utilization of anterior cervical discectomy and fusion.
abstract: Degenerative cervical spondylosis (DCS) is part of the aging process and is the most common reason for degenerative changes with the spinal column. Anterior cervical discectomy and fusion (ACDF) is a major option for operative management of DCS in our institution. This retrospective study investigated the frequency of postoperative complications and resource utilization in 145 patients who underwent ACDF procedures from January 2009 to December 2011. Patients with degenerative changes that involved cervical intervertebral levels C1-C2, spinal injury of traumatic origin, spinal tumors, or previous cervical fusion were excluded. Patients were then further classified into two groups: (1) level 1 or 2 disease (Group M) and (2) level 3 or 4 disease (Group S). Measures of mortality, complications after surgery as well as immediate reoperation for any reason were evaluated. Operation time, length of hospital stay, and hospitalization cost were defined as resource utilization. Ninety seven patients met the inclusion criteria and were further reviewed to characterize the sample better. There were no hematomas, airway complications or deaths, except in one patient who developed postoperative hemorrhage that required immediate surgical intervention, and resolved without any neurological deficit or casualty. Resource utilization indicated that the average operation time for Group S was significantly higher than for Group M (4.31±1.25 vs. 2.88±0.90 hours, p<0.0001). There were no significant differences in length of hospital stay and hospitalization cost between the two groups (p=0.265 and p=0.649). Our results indicate that neurosurgical intervention is safe for patients with DSC. Postoperative complication rates associated with these procedures are low. When surgery is considered appropriate for patients with multilevel diseases, these data suggest that ACDF is a safe surgical option.
