AB  - OBJECTIVES: To assess the predictive value of claims-based outpatient urticaria 
      diagnosis codes to identify potential vaccine-related adverse events (AEs) when 
      recorded on the same day as influenza vaccination. STUDY DESIGN AND SETTING: 
      Health plan members with outpatient claims for influenza vaccination and 
      urticaria on the same day between October 1, 2002, and December 31, 2007, were 
      eligible for inclusion. Electronic medical records (EMRs) for 50 eligible 
      patients with the most recent visits of interest occurring at a large group 
      practice were sampled for review. RESULTS: EMRs were available and reviewed for 
      42 of 50 patients. An influenza vaccination was confirmed in all reviewed medical 
      charts. Urticaria occurring on the day of influenza vaccination was confirmed for 
      40% of participants (17/42); 3 confirmed urticaria diagnoses were potential AEs 
      and 14 urticaria events occurred before vaccination. Among those with unconfirmed 
      diagnoses, 17 had no evidence of urticaria on physical examination on the day of 
      interest (4 had evidence of a nonurticarial rash and 13 had no evidence of rash 
      on examination) and 8 had insufficient information to make a clinical 
      determination. CONCLUSION: Outpatient diagnosis codes for urticaria found in 
      health insurance claims data are limited in their predictive value to identify 
      same-day vaccine AEs.
