AHLTA is the electronic medical record (EMR) system used by medical providers of the U.S. Department of Defense (DoD) since its initial implementation in January 2004. It is a services-wide medical and dental information management system. (According to the DoD, “AHLTA” was never an acronym, but is rather the system’s only name.) AHLTA is a "next generation" system following the Composite Health Care System (CHCS), upon which it builds. It is a clinical documentation engine for the military physicians who write progress notes, put in orders, document procedures performed, and it provides the basis of the medical coding of information into an Oracle database. Additionally, it provides secure online access to all Military Health System (MHS) beneficiaries records for nurses, corpsmen, medics, technicians, clerks and various office managers. The system links the U.S. military’s 481 medical treatment facilities (MTFs), including those deployed abroad, to the EMR, ultimately supporting 9.2 million MHS beneficiaries. It is the first system to allow for the central storage of standardized EHR data that is available for worldwide sharing of patient information. Since 2010, however, multiple improvements have been made to the base software correcting defects and adding new software modules. The latest 3.3.8 version of AHLTA includes the ability to support ICD-10 and all prior versions of AHLTA have been phased out. ==History== The development of AHLTA is directly related to a Presidential Directive issued in 1997. The Directive focused on and reinforced the need for a centralized, longitudinal patient record for military personnel accessible across the DoD enterprise. AHLTA, previously known as the Composite Health Care System II, was developed by the Clinical Information Technology Program Office (CITPO), an acquisitions office for centrally managed MHS clinical information technology systems supporting the U.S. military. (In 2008, CITPO was combined with the TMIP-J Program Office to form the Defense Health Information Management System, or DHIMS.) It began worldwide deployment in January 2004. Unique to AHLTA was the entry of more than 2 years of historical health information for each beneficiary upon the creation of their EHR. This information, transferred from legacy systems, facilitated continuity of care. AHLTA has been deployed in Phases, or "Blocks", of increasing functionality that allows the MHS to build a system that is easily adapted to meet evolving requirements and to incorporate the latest available technology. Block 1 provided the foundation of system: performance through a graphical user interface for real-time ambulatory encounter documentation. It enabled retrieval of a beneficiary's health record at the point of care. By December 2006, Block 1 had been fully deployed and was in use by more than 55,000 MHS care providers in 481 Army, Navy and Air Force treatment facilities worldwide, including Combat Support Hospitals and Battalion Aid Stations in the combat zones of Iraq and Afghanistan. Block 2 (AHLTA version 3.3) was released in December 2008 and integrated robust dental documentation and optometry orders management capabilities (the Spectacles Request Tracking System, or SRTS). Version 3.3.3.X with client update 9.1 is currently fielded to physician and clinic staff workstations. The original plan was to phase in replacements for the CHCS Ancillary modules. However, these blocks of AHLTA were defunded. Subsequent blocks will modernize legacy system ancillary services (laboratory, pharmacy, and radiology), order entry and results retrieval, inpatient documentation, and interface exchange with other MHS information support systems. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Armed Forces Health Longitudinal Technology Application」の詳細全文を読む スポンサード リンク
