Background: The Louisiana Office of Public Health HIV/AIDS Program (OPH HAP) reported that 16,430 people were living with HIV/AIDS (PLWH/A) by December 2008 and 45% of PLWH/A were not in care as indicated by laboratory testing to monitor immune function. Lack of awareness of serostatus, delays in treatment initiation, and disruptions in care contribute to morbidity and mortality, increasing the potential for HIV transmission in the population. Objective/Purpose: Public health information exchanges such as the Louisiana Public Health Information Exchange (LaPHIE) can improve surveillance and linkage into care for PLWH/A. The purpose of this study was to examine whether electronic disease reporting and clinical messaging facilitates rapid identification and linkage into care of newly diagnosed persons, possibly unaware of serostatus, and out-of-care persons. Methods: LaPHIE is a secure bi-directional data exchange linking Louisiana State University Health Care Services Division (LSU HCSD) hospitals and OPH HAP. Evaluation of LaPHIE includes mixed methods (quantitative and qualitative) to measure its impact on access to care as well as public health practice. Cohort data will be used to assess changes in individual and population level HIV/AIDS-related endpoints and utilization effects. Results: Nearly 1100 unduplicated out of care persons could be reached through LaPHIE. Of these ~70% have not accessed care or dropped out of care and ~30% are in need of updated contact information for additional public health follow-up. An estimated 27% are individuals possibly unaware of status and 20% are perinatally exposed children needing follow-up. Qualitative data indicate acceptability in the system's initial rollout phase, with providers and consumers stating a high degree of expectation that the system will improve HIV related healthcare outcomes. Discussion/Conclusions: This study is the first of its kind to examine endpoints using a mixed model approach, preliminarily demonstrating acceptability by providers and consumers as well as positive outcomes.

Learning Objectives:
1. Describe the role of work flow analysis in development of a business case for public health information exchanges. 2. Discuss methodology for evaluation of health information exchanges. 3. Identify opportunities for transforming public health practice through health information exchanges.
