A population-based analysis of time to surgery and travel distances for brachial plexus surgery.
Since the published brachial plexus injuries (BPI) experience is largely from individual centers, the authors used a population-based approach to evaluate the delivery of care for patients with BPI. They found that nearly one third of patients underwent BPI surgery more than 1 year after the injury, with patients initially treated at smaller hospitals at risk for undergoing delayed BPI surgery. These findings can inform efforts to expedite timely referral of patients with BPI to experienced centers.

Chiari malformation type I surgery in pediatric patients. part 1: validation of an ICD-9-CM code search algorithm.
The researchers sought to validate two ICD-9-CM code algorithms using hospital billing data to identify pediatric patients undergoing Chiari malformation Type I (CM-I) decompression surgery. They found that an ICD-9-CM algorithm requiring a primary diagnosis of CM-I has excellent positive predictive value and very good sensitivity for identifying CM-I decompression surgery in pediatric patients. They concluded that these results establish a basis for utilizing administrative billing data to assess pediatric CM-I treatment outcomes.

Long-term reduction of health care costs and utilization after epilepsy surgery.
This study assessed long-term direct medical costs, health care utilization, and mortality following resective surgery in persons with uncontrolled epilepsy. It found that the mean direct medical cost difference between the surgical group and control group was $6,806 after risk-set matching. The incidence rate ratio of inpatient, emergency room, and outpatient utilization was lower among the surgical group in both unadjusted and adjusted analyses.
