Object Recent attempts to control health care costs focus on reducing or eliminating payments for complications, hospital-acquired conditions, and provider preventable conditions, with payment restrictions applied uniformly. A patient's preexisting comorbidities likely influence the perioperative complication incidence. This relationship has not previously been examined in pediatric neurosurgery. Methods The authors conducted a retrospective assessment of prospectively collected relevant patient comorbidities and morbidity and mortality events at a large pediatric neurosurgical unit over a 5-year period. The authors examined the impact of specific comorbidities and the cumulative effect of multiple comorbidities on complication incidence. Results A total of 1990 patients underwent 3195 procedures at the authors' institution during the 5-year study period. Overall, 396 complications were analyzed; 298 patients (15.0%) experienced at least one complication. One or more comorbidities were present in 45.9% of patients. Renal comorbidities were clearly associated with the increased incidence of complications (p = 0.02), and they were specifically associated with infection (p = 0.006). Neurological comorbidities had a borderline association with complications (p = 0.05), and they were specifically associated with death (p = 0.037). A patient's having more comorbidities did not correlate with an increased risk of a perioperative complication (p = 0.8275). Conclusions The complication incidence in pediatric neurosurgery is variable and may be influenced by the type of neurosurgical procedure and patient-related factors. While patient-related factors beyond the control of the provider can significantly impact complications and hospital-acquired conditions in pediatric neurosurgery, an increasing number of comorbidities do not correlate with an increased risk of complications per patient.
