  • Title: Using natural language processing for identification of pneumonia cases from clinical records of patients with serologically proven influenza.

    Journal: AMIA Annu Symp Proc; 2008 Nov 06; ():1165. PubMed ID: 18998814.
    Abstract:
    The purpose of this study was to determine whether influenza vaccination protects against pneumonia in patients who develop influenza. By parsing a data set of records of 1455 patients with serologically proven influenza using SNOMED CT we found that of the vaccinated patients 19.3% developed pneumonia and of the unvaccinated 20.7%. These data suggest that influenza vaccine does not prevent pneumonias in patients who develop influenza despite immunization with influenza vaccine.
