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)
H1N1 laboratory confirmation case details in EDRS (freeform) View Notification From: To: HAWAIIAN ### MORTUARY Subject: NEDSS Status Changed (VSS) Creation date: 02/22/2010 09:00:20 Message: Case NEDSS Influenza Status has been changed to Influenza Test Confirmed as Positive while case has already been Sent to VSS. The new status was modified in NEDSS: No. Confirmation Status Comments: Influenz A/Swine- Positive
