Updates to the Implementation Guide for Syndromic Surveillance

In 2011, the CDC released the PHIN Implementation Guide (IG) for Syndromic Surveillance v.1 under the Public Health Information Network. In the intervening years, new technological advancements, EHR capabilities as well as epidemiological and Meaningful Use requirements have led to the periodic update and revision of the IG through informal and semi-structured solicitation and collection of comments from across public health, governmental, academic, and EHR vendor stakeholders.

HL7 balloting process for the Implementation Guide for Syndromic Surveillance

Syndromic surveillance seeks to systematically leverage health-related data in near "real-time" to understand the health of communities at the local, state, and federal level. The product of this process provides statistical insight on disease trends and healthcare utilization behaviors at the community level which can be used to support essential surveillance functions in governmental public health authorities (PHAs).

Ensuring confidentiality and safety of cancer registry data in Kumasi, Ghana

Cancer registration involves collecting information on patients with cancer. Population-based cancer registries in particular are useful in estimating the disease burden and to inform the institution of prevention and control measures. Collecting personal information on patients with cancer requires strict adherence to principles of confidentiality to ensure the safety of the collected data. Failure may have legal and medical implications. The Kumasi Cancer Registry was established as a population-based cancer Registry in 2012.

PHIN Message Quality Framework (MQF)

The PHIN Message Quality Framework (MQF) is a web application that assists public health practitioners with preparing and communicating quality standard electronic messages as defined by the applicable messaging, vocabulary, and programmatic standards. This framework allows users to upload HL7 2.3.1 and 2.5.1 messages for Meaningful Use message validation for Electronic Laboratory Reporting, Immunization, and Syndromic Surveillance.

Comparison of Air Passenger Travel Volume Data Sources for Biosurveillance

The National Biosurveillance Integration Center (NBIC) has the responsibility to integrate, analyze, and share the nation’s biosurveillance information provided from capabilities distributed across public and private sectors. The integration of information enables early warning and shared situational awareness of biological events to inform critical decisions directing response and recovery efforts.

HIT Conformance Testing: Advancing Syndromic Surveillance System Interoperability

Speed, reliability, and uniformity of data collection enable syndromic surveillance (SyS) systems to provide public health authorities (PHAs) with timely information about community health threats and trends. Increasingly, healthcare information technology (HIT) is being used to accelerate and automate data collection for more real-time surveillance, reducing irregularity in how SyS data are packaged and sent by healthcare providers.

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.
