The collection of health care statistics began during the Revolutionary War. The early methods of collecting data were very primitive but eventually evolved into the elaborate computer-assisted health care information systems of today.
In 1818, the first Surgeon General established an accurate, organized, and consistent system of record-keeping by having all medical records and reports submitted to his office in Washington, DC, for preservation. The first Surgeon General's Report was printed in 1822 and was published annually until 1942.
The Army Medical Department (AMEDD) was reorganized in 1862 to give The Surgeon General additional status, rank, and medical personnel. A medical records section was established to maintain statistical data collected during the Civil War and to provide an accurate medical history of the war.
In 1890, the Medical Record Section acquired a Hollerith electrical sorting and tabulating machine which tremendously increased its statistical-gathering capability. After the outbreak of World War I, a more sophisticated tabulating system was acquired, and the Medical Records Section grew in size and importance. It was renamed the Medical Statistics Division, authorized a staff of 25, and provided data for several official medical publications as one of its functions. The Medical Statistics Division was the forerunner of the present organization and changed very little between World War I and World War II.
In 1942, reorganization of the Office of The Surgeon General (OTSG) created the Medical Statistics Agency to maintain statistics relating to all theaters of war.
The Health of the Army series was developed in 1943 to publish, on a monthly basis, morbidity information and hospital inpatient and outpatient workload statistics. The agency continued to collect and process data; provided statistics for Army medical publications; and functionally, changed very little during the succeeding 30 years. After 44 years, The Health of the Army was discontinued with the December 1988 issue. The PASBA felt that customers could be served better and faster by developing customized reports based upon the individual needs. Requests for inpatient data would be directed to the Special Studies Branch.
1970...the agency was renamed the Patient Administration and Biostatistics Section under the Plans, Supply and Operations Directorate, OTSG.
1973...the AMEDD was reorganized to create the U.S. Army Health Services Data Systems Agency, and the Patient Administration and Biostatistics Section was placed under that agency.
1974...the systems development and maintenance mission of the U.S. Army Health Services Data Systems Agency was merged with the Patient Administration and Biostatistics Section, OTSG, to create the U.S. Army Health Information Systems and Biostatistics Activity (HIS&BA). At that time, HIS&BA became a field operating activity (FOA) of U.S. Army Health Services Command (HSC) (which later became the U.S. Army Medical Command (MEDCOM), with duty station at Fort Sam Houston, Texas.
April 1977...an additional reorganization took place separating the Patient Administration Systems and Biostatistics element and the Health Care Systems Support Element into two entities creating the U.S. Army Patient Administration Systems and Biostatistics Activity (PAS&BA) with approximately 92 civilian and military personnel. The Health Care Systems Support Element became the U.S. Army Health Care Systems Support Activity (HCSSA). The two entities became two separate FOAs under HSC.
March 1988...the Office of the Chief, the Patient Administration Division (PAD), the Patient Affairs Branch, and the patient records portion of the Patient Records and Special Activities Branch, Deputy Chief of Staff Clinical Services, HSC, were reassigned to PAS&BA. The former Chief, PAD, HSC, became the Commander, PAS&BA; the Medical Records Administrator was transferred to the Office of the Commander, PASBA; and the Patient Affairs Branch was renamed the Patient Administration Operations Division.
1989...the acronym PAS&BA was changed to PASBA.
1 October 1991...the Medical Expense and Performance Reporting System (MEPRS) Division was transferred from the Deputy Chief of Staff for Resource Management, Headquarters, HSC, to PASBA.
2 October 1992...PASBA was transferred to U.S. Army Medical Department Center and School (AMEDDC&S) as a directorate; Directorate of Patient Administration Systems and Biostatistics Activity. (The ACRONYM stayed the same.)
1 February 1994...the Patient Administration Operations Division was transferred to the MEDCOM (Provisional), Clinical Operations Directorate, Patient Administration Division.
9 June 1996...PASBA was reorganized as the Customer Service Division/PASBA (CSD/PASBA) under the newly created Corporate Executive Information System (CEIS) Program Office, OTSG, with duty at HCSSA, Fort Sam Houston, TX. The MEPRS Division was transferred from CSD/PASBA, CEIS, to HCSSA.
1 April 1997...CEIS Program Office was reassigned to the U.S. Army Management Information Systems Support Activity (USAMISSA) with duty station remaining at OTSG; the CSD/PASBA duty station remaining at Fort Sam Houston, TX.
2 April 1998...CSD/PASBA was transferred to Program Analysis and Evaluation (PA&E) Directorate, Office of the Surgeon General. Once again, CSD/PASBA became Patient Administration Systems and Biostatistics Activity (PASBA) with duty remaining at Fort Sam Houston, TX.
1 July 2006...became a component of Decision Support Center (DSC), Office of the Surgeon General. PASBA retains the name Patient Administration Systems and Biostatistics Activity (PASBA) with duty location at Fort Sam Houston, TX.
1 June 2009 PASBA became a component of PA&E Directorate, Office of the Surgeon General with location at Fort Sam Houston, TX.
