Abstrakt: Object: Cerebrospinal fluid shunts are the mainstay of the treatment of hydrocephalus. In past studies, outcomes of shunt surgery have been analyzed based on follow-up of 1 year or longer. The goal of the current study is to characterize 30-day shunt outcomes, to identify clinical risk factors for shunt infection and failure, and to develop statistical models that might be used for risk stratification.
Methods: Data for 2012 were obtained from the National Surgical Quality Improvement Program-Pediatrics (NSQIP-P) of the American College of Surgeons. Files with index surgical procedures for insertion or revision of a CSF shunt composed the study set. Returns to the operating room within 30 days for shunt infection and for shunt failure without infection were the study end points. Associations with a large number of potential clinical risk factors were analyzed on a univariate basis. Logistic regression was used for multivariate analysis.
Results: There were 1790 index surgical procedures analyzed. The overall rates of shunt infection and shunt failure without infection were 2.0% and 11.5%, respectively. Male sex, steroid use in the preceding 30 days, and nutritional support at the time of surgery were risk factors for shunt infection. Cardiac disease was a risk factor for shunt failure without infection, and initial shunt insertion, admission during the second quarter, and neuromuscular disease appeared to be protective. There was a weak association of increasing age with shunt failure without infection. Models based on these factors accounted for no more than 6% of observed variance. Construction of stable statistical models with internal validity for risk adjustment proved impossible.
Conclusions: The precision of the NSQIP-P dataset has allowed identification of risk factors for shunt infection and for shunt failure without infection that have not been documented previously. Thirty-day shunt outcomes may be useful quality metrics, possibly even without risk adjustment. Whether important variation in 30-day outcomes exists among institutions or among neurosurgeons is yet unknown.
