Alcohol intoxication and its effects on traumatic spinal cord injury outcomes.

There are sparse data regarding the impact of alcohol on in-hospital complications associated with traumatic spinal cord injuries (TSCIs). We set out to quantify the impact of alcohol on TSCI outcomes and its influence on health care cost and utilization. The National Trauma Data Bank (NTDB) Research Data Set version 7.2 (2000-2006) was utilized to gather data between 2007 and 2009. We extracted cases of TSCI (International Classification of Diseases, Ninth Revision, Clinical Modification codes 806.xx) without concurrent traumatic brain injury. Outcomes of interest were mortality, length of stay (LOS), intensive care unit (ICU) days, ventilator days, and complications. Continuous outcomes such as LOS, ICU days, and ventilator days were analyzed using linear regression. Risk-adjusted analysis of risk factors for mortality and complication rates were performed using multiple logistic regression. Of the 10,611 persons identified in the NTDB, alcohol was present in approximately one fifth of all cases (20.76%). A majority of TSCI patients were young (mean age, 39 years) Caucasian (65.07%) males (75.93%). Blunt injury was the most common mechanism of injury. The presence of alcohol did not significantly affect mortality or neurological complications. Alcohol in the blood was associated with extended LOS, longer ICU stays, more days spent ventilated, and increased risk of all-type complications. Further, there was a statistically significant association with the presence alcohol and increased risk for pulmonary, pneumonia, deep vein thrombosis and pulmonary embolism, urinary tract infection, and ulcer/skin complications. Alcohol intoxication is associated with increased in-hospital morbidity. The significant association with in-hospital complications increases health resource utilization after spinal cord injury.
