How to Effectively Validate an HL7 Syndromic Surveillance Interface

Current local, state, and national initiatives related to meaningful use and the modernization of electronic health records, and the growing availability of electronic information exchanges, have become important drivers to establishing syndromic surveillance systems. Effective implementation of electronic syndromic surveillance interfaces requires approaches that ensure the receipt of quality, timely, and reliable information.

Evaluation of Hepatitis C Surveillance in Washington State

Hepatitis C is a nationally notifiable viral infection that occurs as a result of parenteral contact with infected body fluids. An estimated 3.5 million persons are currently infected with HCV.1 Infection status is divided into acute (short-term, onset within 6 month of exposure) and chronic (long-term). For most people (75-85%), acute HCV infection leads to chronic infection.2 Those with chronic infection remain relatively asymptomatic until the infection becomes severe enough to be recognized or the infected individual is screened for infection with hepatitis C.

Evaluation of Legionellosis Surveillance in Michigan Focusing on Diagnostic Testing

In Michigan, both presentations of legionellosis, Pontiac Fever (PF) and Legionnaires’ Disease (LD), are reportable through the Michigan Disease Surveillance System (MDSS), a web-based electronic database. Legionella pneumophila serogroup 1 is responsible for 5090% of cases.1,2 Several diagnostic tests are available with varying sensitivities and specificities. Urinary Antigen testing (UAg) is the most commonly used test but only reliably detects L. pneumophila-1.

A Suggestion to Improve Timely Feedback of Infectious Disease Surveillance Data at a Provincial Level in South Korea

In South Korea, the NNDSS is organized at three levels: local, provincial, and central. At the local level, physicians report the cased to the Public Health Center (PHC) and PHC conduct control measures. At the provincial level, the PHC reports the cases to the Department of Health (DOH) of the province and DOH obliged to report the cases to the Korea Centers for Disease Control and Prevention (KCDC) and feedback of the surveillance data to PHC and physicians.

Evaluation of the Measles Case-Based Surveillance System in Kaduna State (2010-2012)

In Africa, approximately 13 million cases of measles and 650,000 deaths occur annually, with sub-Saharan Africa having the highest morbidity and mortality (1). Measles infection is endemic in Nigeria and has been documented to occur all year round despite high measles routine and supplemental immunisation coverage (2,3). The frequent outbreaks of Measles in Kaduna State prompted the need for the reevaluation of the Measles case-based surveillance system.

A Timeliness Study of Disease Surveillance Data Post ELR Implementation in Houston

Since 2009, Houston Health Department (HHD) uses an electronic disease surveillance system (Maven) to receive ELRs from reporting facilities in the Houston jurisdiction. Currently, two large hospital systems, a blood bank, two large commercial labs, and two public health labs are sending ELRs to Maven. The overall percentage of disease reports received via ELR was over 50%. We hypothesize that the implementation of ELR has improved the timeliness and completeness of disease surveillance.

Evaluation of Vaccine Preventable Diseases (Measles and Diphtheria) Surveillance System - Delhi, India, 2013

The vaccine preventable diseases (VPDs) of measles and diphtheria in India were responsible for 47% of global measles mortality and 20% of global diphtheria mortality in 2010. We evaluated the VPD surveillance system of Delhi, focusing on measles and diphtheria.


The specific objective was to evaluate the VPD surveillance system of Delhi, focusing on measles and diphtheria.

A Tool to Improve Communicable Disease Surveillance Data

NYS (excluding NYC) has a very robust Communicable Disease Electronic Surveillance System (CDESS). This system provides disease specific modules, as well as a tracking system for contacts, and a perinatal infant tracking system. This system provides an easy way for users to quickly download a file with all of their data.

Preliminary Look into the ICD9/10 Transition Impact on Public Health Surveillance

On October 1, 2015, the number of ICD codes will expand from 14,000 in version 9 to 68,000 in version 10. The new code set will increase the specificity of reporting, allowing more information to be conveyed in a single code. It is anticipated that the conversion will have a significant impact on public health surveillance by enhancing the capture of reportable diseases, injuries, and conditions of public health importance that have traditionally been the target of syndromic surveillance monitoring.
