Costs, length of stay and inpatient complications of early surgical decompression after spinal cord injury in a geriatric cohort.

Debate regarding timing of surgical decompression after spinal cord injury continues. Recent evidence indicates that early decompression improves neurological outcomes. However, little investigation has been performed regarding how it affects one's hospitalization in a geriatric cohort. 8,999 cases of traumatic SCI who underwent surgical decompression (2002-2011, age 65 + years) within the Nationwide Inpatient Sample were included in univariate and multivariate analyses. Univariate analysis shows that early decompression is more cost effective ($88,564.00 vs $107,849.00, p < 0.0005) and is associated with shorter length of stay (LOS) (8.00 ± 16.15 vs 12.00 ± 15.93 days, p < 0.0005) when compared to late decompression. In multivariate analysis, early decompression continued to be associated with a shorter LOS, though cost was no longer statistically different. Early decompression had less odds of surgical site infection, vasopressor use, decubitus ulcers, but higher odds of cardiac complications, acute renal failure, transfusions and hardware complications. Spinal level of SCI did not affect timing of surgery. Vertebral column fracture did not influence cost or length of stay. In summary, the complex mix of results regarding inpatient complications highlight the innumerable variables and complex decision making that involves surgical treatment of SCI, especially within a susceptible geriatric cohort. However, shorter LOS and lower costs associated with early decompression continue to support its uniform implementation after traumatic SCI.
