The Effect of Hospital Transfer on Patient Outcomes After Rehabilitation for Spinal Injury

OBJECTIVE: Spine fractures, including associated spinal cord injury, account for 3%-6% of all skeletal fractures annually in the United States. Patients who undergo interhospital transfer after injury may have a greater likelihood of nonroutine disposition, longer hospital stay, and higher cost. We evaluated the effects of patient transfer on functional outcomes after spine trauma. METHODS: Patients were treated after acute traumatic spine injury at a rehabilitation hospital in 2011-2017. Compared patients were those directly admitted to the tertiary hospital or transferred from a community hospital. RESULTS: A total of 188 patients (mean age 46.1 +/- 18.6 years, 77.1% men) were evaluated, including 130 (69.1%) directly admitted and 58 (30.9%) transferred patients. The most common levels of injury were at C5 (19.1%) and C6 (12.2%), and most injuries were American Spinal Injury Association injury severity score grade D (33.2%) or grade A (32.1%). No statistical difference in age, injury pattern, timing from injury to surgery, or rehabilitation length of stay was seen between admitted and transferred patients. A significant improvement in ambulation distances was seen at discharge for directly admitted compared with transferred patients (447.7 +/- 724.9 vs. 159.9 +/- 359.5 feet; P = 0.005). However, no significant difference primary outcomes, namely American Spinal Injury Association injury severity score distribution (P = 0.2) or Functional Independence Measures (Delta 30.9 +/- 15.9 vs. 30.1 +/- 17.1; P = 0.7), were seen between admitted and transferred patients at time of rehabilitation discharge. CONCLUSIONS: Interhospital transfer status did not diminish time to rehabilitation after injury or reduce functional recovery, suggesting early surgical treatment in community settings may have merit prior to transfer.
