During the 2009 H1N1 influenza pandemic, the Washington State Department of Health (DOH) temporarily made lab-confirmed influenza hospitalizations reportable. Reporting of influenza hospitalizations is resource intensive for hospitals and local health jurisdictions. As a result, electronic sources of influenza hospitalization data are being explored. A Regional Health Information Exchange (HIE) in Washington currently sends DOH ICD9 coded discharge diagnoses and microbiology laboratory orders and results for all patients admitted to 17 hospitals throughout Washington, including four of the five hospitals in Spokane County. The HIE hospitalization and laboratory data may be a valuable replacement for mandatory notifiable condition reporting to monitor the basic epidemiology and severity of influenza in Washington.

Objective

To evaluate the sensitivity, positive predictive value (PPV), timeliness, completeness, and representativeness of lab-confirmed influenza hospitalization data from a health information exchange with respect to traditional notifiable condition reporting.

During summer 2012, Washington State Department of Health (WA DOH) surveyed ILINet providers and found that more than half either utilize their electronic medical record system (EMRS) to gather and report weekly ILINet data, or intend to implement queries to do so in the future. There are a variety of EMRS being used state-wide, and providers that currently utilize these systems to report ILINet data apply a wide range of methods to query their data. There exists great interest in the evaluation of ambulatory care data within the context of Meaningful Use and little research is published in this area. WA DOH sought to evaluate electronic data from WA outpatient clinic networks in order to determine if a syndromic ILI definition previously validated for emergency department (ED) data accurately identified ILI visits in electronic ambulatory care data.

Objective:

To determine if a syndromic influenza-like illness (ILI) definition previously validated for emergency department (ED) data accurately identified ILI visits in electronic ambulatory care data.
