Use of electronic health records in disaster response: the experience of Department of Veterans Affairs after Hurricane Katrina.

Abstract

We describe electronic health data use by the Department of Veterans Affairs (VA) in the month after Katrina, including supporting technologies, the extent and nature of information accessed, and lessons learned. We conducted a retrospective study using cross-sectional panels of data collected sequentially over time. By September 30, 2005, clinical data were accessed electronically for at least 38% (14941 of 39910) of patients cared for prior to Hurricane Katrina by New Orleans-area VA medical facilities. Approximately 1000 patients per day had data accessed during the month following Hurricane Katrina, a rate approximately two thirds of pre-Katrina values. Health care data were transmitted to more than 200 sites in 48 states and to at least 2300 users. The VA electronic health records supported continuity of care for evacuated veterans after Katrina. Our findings suggest that pharmacy and laboratory computerization alone will not be sufficient for future disaster support systems.
