Establishing a High-Risk Neuroblastoma Cohort Using the Pediatric Health Information System Database

摘要

International Classification of Diseases, 9th Revision (ICD-9) code(s) for neuroblastoma do not exist, preventing identification of these patients in administrative databases. To overcome this challenge, a three-step algorithm, using ICD-9 codes, exclusion criteria, and manual review of chemotherapy billing data, was utilized to assemble a high-risk neuroblastoma cohort (n=952) from the Pediatric Health Information System (PHIS) Database and validated at a single institution [sensitivity 89.1%; positive predictive value (PPV) 96.1%]. This cohort provides a data source for future comparative effectiveness and clinical epidemiology studies in high-risk neuroblastoma patients. Pediatr Blood Cancer 2014;61:1129-1131.
