Syndromic Surveillance Case Definition Development Using Recursive Partitioning Techniques for Highly Dimensional Databases
Content Type: Abstract
Seasonal influenza accounts for a high proportion of outpatient morbidity during the winter months. However, influenza case counts are greatly underestimated due to frequently undiagnosed influenza. Electronic medical record (EMR… read more… following database tables: age, vital signs, reason for visit, procedures (CPT), and diagnoses (ICD-9). 10-fold … rate, 51 CPT codes, 46 ICD-9 codes, and 41 ‘reasons for visit’ were identified for the final model analysis.
