Abstract

In 2008, the Centers for Disease Control and Prevention awarded contracts to health information exchanges in Indiana, New York and Washington/Idaho to accelerate public health situational awareness. Awardees in each state have disseminated their findings and lessons at professional conferences and in peer-reviewed journals. The dissemination formats ranged from papers, oral presentations, posters, panels and demonstrations at interoperability showcases. With a focus on health information exchange and public health, topics included biosurveillance, electronic laboratory reporting, broadcast messaging, and notifiable disease surveillance. Each presentation is summarized in this bibliography, and the authors affiliated with each site are highlighted.


Introduction

With funding from the Centers for Disease Control and Prevention (CDC) in February 2008, the “Accelerating Public Health Situational Awareness through Health Information Exchanges” project was initiated in three locations: Indiana, New York and Washington/Idaho. This paper is an annotated bibliography of the peer-reviewed and grey literature publications and presentations by the three Health Information Exchanges (HIEs). These HIEs implemented the capability to electronically move clinical information between disparate health care and public health information systems while maintaining the meaning of the information being exchanged. For this project, HIEs have developed real-time, nationwide public health event-monitoring capability to assist with and improve early event detection, public health situational awareness, outbreak management, and countermeasure and response administration. In addition, the HIEs are collaborating on a consortia level to cooperatively develop specifications for and trial implementations of the emerging and interoperable “network of networks” that is the Nationwide Health Information Network (NHIN).

Each HIE represents a wealth of innovative patient- and population-based experience from public health practice, academia, business, and computing and information technology fields. Furthermore, each HIE has contributed to improving the operation of information technology systems and secure exchange of data and information to enhance early detection and a rapid response to and management of public health emergencies. This annotated bibliography represents the material outputs of each HIE’s participation in the accelerating public health situation awareness initiative funded by the CDC.

Painter I, Bugni P, Trebatoski M, Revere D, Karras B, Dobbs D, Lober W. Potential to estimate vaccine uptake in an emerging epidemic using data from a Health Information Exchange. 2010 CSTE Annual Conference, June 2010.

Summary: A report regarding the ability of HIEs to provide real- or near real-time vaccination information during an epidemic when obtaining vaccination uptake information is critical for decision-making about targeted vaccination efforts. Using data obtained through the Northwest Public Health Information Exchange (NWPHIE), the authors reported that sufficient self-reported vaccination data is present in the HIE data to make it usable for vaccination surveillance. In addition, in comparison to other methods for obtaining this data, NWPHIE provides nearly real-time provision of relevant data for surveillance by Washington State Department of Health.

Grannis S, Friedlin J, Overhage JM, Merriwether R. Practical Aspects of an Operational Open Source Notifiable Condition Detection System. 2009 PHIN Annual Conference, August 2009.

Summary: Building on standards for message structure and content (HL7 and LOINC®), the Indiana Network for Patient Care HIE has implemented and maintained an automated notifiable condition reporting system that receives real-time HL7 clinical results from a variety of HIE stakeholders, translates these disparate proprietary codes into LOINC codes, determines whether the results carried by the message indicates a notifiable condition by checking the abnormal flag sometimes contained in the message, or by comparing the test results with criteria in the PHIN notifiable conditions mapping table. This presentation covered expansion of the notifiable condition processor infrastructure to create a modular notifiable condition processor, the--Notifiable Condition Detector (NCD)--which is re-usable by other HIEs and public health stakeholders.

Summary: The authors establish and evaluate a method for measuring the utility of biosurveillance data using Multi-Attribute Utility Theory (MAUT). MAUT is used to assess and rank the risks of a decision-maker’s preferences. In this paper, the authors apply this theory to measure the utility of biosurveillance data using a time-tradeoff exercise. Empirically, the method shows initial promise for evaluating a minimum data set for biosurveillance. The authors suggest that future applications of this approach may prove useful in disease surveillance planning and evaluation.

Lecture Notes in Bioinformatics, vol 5354 (Proceedings of the 2008 International Workshop on Biosurveillance and Biosecurity). Berlin: Springer, pp. 10–21.

Summary: This paper describes support for three public health practice domains—biosurveillance, case reporting, and communication from public health to providers through integrated decision support—in demonstrations of a model HIE. The model HIE implements interoperability through the use Integration Profiles standards that support specific data transfer use cases. These methods were validated for each public health domain in a distributed environment in national showcase demonstrations. The authors believe that this work has implications for the integration of public health functions into any HIE, regardless of architecture and may be extended to strengthen development of the Public Health Grid.

Summary: The value of sharing data among HIEs and public health is demonstrated by improving newborn screening follow-up by identifying infants who may lack screening. This use case requires a robust matching process for linking vital records data with newborn screening results to identify unscreened infants. The Indiana Network for Patient Care has implemented a configurable, generalized probabilistic method to perform the matching using an open-source probabilistic matching tool. The design and implementation of the system is described and results for matching infant data across multiple organizations is presented.
