This study showcases the implementation of an automated system for reporting and validating influenza and pneumonia deaths using laboratory confirmation. The system operates within the Hawaii Electronic Death Registration System (EDRS) and ensures timely and accurate reporting through electronic notifications to relevant health authorities. With improved efficiency and accuracy, this system enhances mortality surveillance capabilities, aids in disease outbreak detection, and protects decedent privacy.

Automated Influenza and PneumoniaReporting in anElectronicDeathRegistrationSystem validated with Laboratory ConfirmationAlvin T. Onaka, Ph.D. Hawaii Department of HealthOffice of Health Status Monitoring
Influenza Deaths • CDC Case Definition Influenza listed anywhere on the death certificate (Part I or Part II) • Exclusions Haemophilus influenzae Parainfluenzae virus
Pneumonia Deaths • CDC Case Definition Pneumonia listed anywhere on the death certificate (Part I or Part II) • Exclusions Aspiration pneumonia Pneumonitis Pneumococcal meningitis
Case Definitions (continued) • If both pneumonia and influenza are listed, count as influenza
Weekly Mortality Reporting • Previous Procedure • Deaths due to Influenza or Pneumonia manually counted by DOH staff • No timely means of lab confirmation from other DOH branch that electronically reports lab data (ELR)
Worksheet turned in to DOH and enters info. into system. DOH manually identifies Influenza & Pneumonia Weekly mortality report manually run from data system Funeral Director gives death worksheet to certifier to complete Previous Mortality Reporting Procedure
Weekly Mortality Reporting • New Methodology • New automated method of identifying Influenza or Pneumonia cases via the Hawaii Electronic Death Registration System (EDRS) • New electronic laboratory confirmation between EDRS and ELR
EDRS At scheduled times, mortality reports automatically sent via email to Disease Outbreak Control Division & Vital Statistics Internet Internet Certifier enters COD in EDRS NEDSS Later, Influenza/ Pneumonia lab results matched & results confirmed Current Weekly/Daily Mortality Reporting Procedure
Automated Mortality Reports • Adjustable interval for either hourly, daily or weekly automated reporting • In addition to Pneumonia and Influenza case identification, custom reports are possible for future disease outbreaks (i.e. Syndromic Surveillance)
Automated Mortality Reports • Every automated email notification includes: • 1. Summary report in PDF format pattered after CDC’s weekly mortality report
Automated Mortality Reports (continued) • Every automated email notification includes: • 2. Excel spreadsheet showing Pneumonia and Influenza indicators, a unique case ID of decedent and the full literal COD text as entered by the certifier
Excel Spreadsheet Influenza & Pneumonia Indicators Full literal text of COD by certifier Unique decedent ID
Automated Mortality Reports (continued) • Spreadsheet allows review of Influenza & Pneumonia status & pertinent certifier information for all deaths • With full COD available, trained reviewers can ignore computer triggered flags and request record review of possible Influenza cases missed by computer • Decedent privacy protected since DOH reviewers only see a Case ID
Influenza & Pneumonia Indicators Full literal text of COD by certifier Unique decedent ID Excel Spreadsheet–example 2
Increasing Accuracy for Mortality Reporting and COD in general • Incorporation of spell checker from NCHS’s SuperMICAR • Spell checker reviews COD field and opens up a spell check box for certifier to accept or change possible misspelled word(s)
H1N1 Influenza Mortality Surveillance • CDC Interim H1N1 Flu Surveillance Recommendation • For vital statistics offices, CDC requests daily reporting
H1N1 Influenza Mortality Surveillance • May 3, 2009 Daily Report
Lessons Learned from H1N1 Surveillance • Medical Examiners and Coroners often certify record with “deferred – pending lab results”. • The current automated reporting system will miss these Influenza cases
Lessons Learned (continued) • Drop to paper cases include backdated certification information • Automated reporting system will also miss these cases
+ DOH-DOCD receives all lab results electronically with an Electronic Laboratory Reporting System (ELRS) Physicians in hospital or clinic suspects respiratory disease and orders lab test DOH-DOCD identifies and investigates positive Influenza lab results How Hawaii’s Influenza Cases are First Identified
EDRS Internet Internet Certifier enters COD with key terms such as Influenza, H1N1, {other} in EDRS DOH-DOCD staff receive automated EDRS email or for ‘Drop to Paper’ a direct email from Vital Stats staff via manual email DOH-Vital Stats staff enters COD for ‘Drop to Paper’ certification and identifies Influenza case before EDRS How Hawaii’s Influenza Cases are First Identified (continued)
Hawaii’s Confirmed H1N1 Influenza Death Cases • 13 confirmed cases occurred in about a 1 year time period. • About 24% cases first identified by the automatic email mortality reporting system • About 38% cases first identified by Vital Statistics staff who entered in COD that was completed non-electronically • About 38% cases first identified by Disease Outbreak Control Division (DOCD) staff from their Electronic Laboratory Reporting system (ELRS)
