MILITARY HERITAGE — VA & DOD CARE

The Largest Integrated Health System in America

From Lincoln's promise "to care for him who shall have borne the battle" through today's 9-million-veteran VA and the global DoD military health system — federal medicine has shaped how America defines integrated, longitudinal, evidence-driven care.

A System Built on a Promise

The U.S. federal commitment to caring for veterans dates to the closing months of the Civil War. President Lincoln's Second Inaugural Address — delivered March 4, 1865 — included the line that became the moral charter of American veteran healthcare: "to care for him who shall have borne the battle, and for his widow, and his orphan." Six weeks later, Congress chartered the National Asylum for Disabled Volunteer Soldiers — the first federal medical facility purpose-built for veterans, and the most distant ancestor of today's Veterans Health Administration.

The system that grew from that promise is now the largest integrated healthcare delivery enterprise in the United States. The Veterans Health Administration operates more than 1,300 facilities and serves roughly 9 million veterans annually. The Defense Health Agency, established in 2013, runs medical services for 9.6 million active-duty service members, retirees, and dependents through the TRICARE program and a global network of military treatment facilities. Together, federal medicine has been the laboratory in which the United States invented modern integrated care, the multicenter clinical trial, the electronic health record, and most of what civilian trauma medicine takes for granted.

Federal Medicine's Defining Moments

1798

Marine Hospital Service Established

President John Adams signs "An Act for the Relief of Sick and Disabled Seamen," creating the Marine Hospital Service — the first federal healthcare program in U.S. history and the direct ancestor of the U.S. Public Health Service.

1865

National Asylum for Disabled Volunteer Soldiers

Six weeks after President Lincoln's Second Inaugural Address, Congress charters the first federal medical facility for veterans. Branches open across the country in the years that follow — the seed of the modern VA hospital network.

1921

Veterans Bureau Created

President Harding consolidates fragmented WWI veterans' care into a single Veterans Bureau — the first attempt to centralize federal veteran healthcare administration after the chaos of the post-war demobilization.

1930

Veterans Administration (VA) Established

Executive Order 5398 consolidates the Veterans Bureau, the National Home for Disabled Volunteer Soldiers, and the Bureau of Pensions into a single Veterans Administration — the agency Americans would know for the next 59 years.

1946

VA–Medical School Affiliations

Policy Memorandum No. 2 establishes the VA's affiliation policy with U.S. medical schools — pairing every major VA medical center with an academic teaching program. This is the model that produces ~70% of all U.S. physicians' clinical training experience today.

1989

Department of Veterans Affairs (Cabinet)

President Reagan signs the Department of Veterans Affairs Act, elevating the VA to cabinet-level status. The change recognizes federal veteran care as a national priority on par with Defense, State, and Treasury.

1995

The Kizer Reorganization

Under VHA Undersecretary Dr. Kenneth Kizer, the Veterans Health Administration is reorganized into 22 Veterans Integrated Service Networks (VISNs), shifts from inpatient-centric to primary-care-centric service delivery, and rolls out the VistA electronic health record system-wide. Civilian health systems study the redesign for the next two decades.

2009

DoD–VA Joint EHR Initiative

The Department of Defense and Department of Veterans Affairs launch the Virtual Lifetime Electronic Record (VLER) program, attempting unified medical records across active-duty service and veteran care — a precursor to today's joint Cerner / Oracle Health rollouts at both agencies.

2013

Defense Health Agency Stood Up

The DoD consolidates Army, Navy, and Air Force medical support functions under the Defense Health Agency (DHA), creating a unified joint command for the Military Health System and TRICARE administration.

2014

Veterans Choice Program

The Veterans Access, Choice, and Accountability Act creates the Veterans Choice Program — allowing veterans to receive care from non-VA community providers under defined access conditions. Civilian providers begin to partner directly with VA networks at scale.

2018

VA MISSION Act

The MISSION Act consolidates and expands community-care authorities, modernizes the VA's caregiver support program, and authorizes the Asset and Infrastructure Review Commission. It is the most significant statutory restructuring of veteran healthcare access since 1995.

Today

The Largest Integrated Health System in the Country

The Veterans Health Administration operates more than 1,300 facilities for ~9 million enrolled veterans. The Defense Health Agency runs ~700 military treatment facilities globally and administers TRICARE for ~9.6 million beneficiaries. Together they remain the proving ground for integrated, longitudinal care in the United States.

From Federal Medicine to Civilian Care

Many of the things a civilian health system now treats as standard — from the integrated EHR to the multicenter clinical trial to the multidisciplinary wound clinic — were invented or scaled inside VA and DoD facilities.

1958

Implantable Cardiac Pacemaker

Wilson Greatbatch's implantable pacemaker was developed and clinically validated through the Buffalo VA Medical Center. The device is now ubiquitous in civilian cardiology — and the development pathway became a template for VA-academic medical-device collaboration.

1963

Liver Transplantation

Dr. Thomas Starzl performed the first human liver transplant at the University of Colorado, with much of the foundational immunosuppression and surgical-technique research carried out at the Denver VA and later Pittsburgh VA. Civilian transplant programs grew directly from VA-affiliated work.

1972+

VA Cooperative Studies Program

The VA-CSP is one of the longest-running multicenter clinical trial programs in the world. Its methodology — randomized, multi-site, federally coordinated — became the gold standard that civilian and pharmaceutical multicenter trials adopted.

1985+

VistA — The First Modern Integrated EHR

VistA (Veterans Health Information Systems and Technology Architecture) was the first widely-deployed integrated electronic health record in the United States. Its open-source descendants (OpenVistA, WorldVistA) and its design principles influenced every commercial EHR that followed.

1990s+

Multidisciplinary Wound Care Centers

The VA pioneered the multidisciplinary wound-care clinic model — vascular, podiatry, plastic surgery, infectious disease, and nursing in one coordinated team. Today's civilian wound-center industry follows the staffing and protocol design that originated in VA limb-salvage programs.

2003+

VA Telemedicine at Scale

The VA rolled out the largest sustained telehealth program in U.S. history more than a decade before COVID-19. Civilian telehealth platforms drew directly on VA experience in chronic-care management, mental-health visits, and rural specialist coverage.

2011+

Million Veteran Program

VA's Million Veteran Program is one of the largest genomics-and-health-records research databases in the world. Findings from MVP have informed civilian precision medicine and population-genomics protocols across cardiovascular disease, oncology, and psychiatry.

Modern

Advanced Prosthetics & Limb Salvage

Post-WWII VA prosthetics research, accelerated by the OEF/OIF combat-amputation cohort, drove the modern myoelectric prosthetic, the C-Leg, and the targeted-muscle-reinnervation surgical technique. Civilian amputee care draws directly on VA-DoD R&D.
