VistAWeb was also made available broadly, though temporarily, to assist clinical staff with the retrieval of patient information from the sites affected by damage caused by hurricane Katrina. VistAWeb was also expanded for to access patient records from the DoD AHLTA patient record system in 2009. This relied on mapping data from AHLTA via a bidirectional data exchange system to VistA. Due to errors in the bidirectional exchange system, erroneous data was transmitted to the VA, causing this remote viewer function from DoD sites to be closed. The VistAWeb package is distributed in the public domain as a module of the VistA software package under the Freedom of Information Act (FOIA). It is therefore available from the VA FTP site, from the VA software distribution office, and in bundled packages. Its capabilities, therefore, can be achieved by a healthcare institution that installs the VistA electronic health record.
