Ten-Year Outcomes of a Systems-Based Approach to Longitudinal Amputation Care in the US Department of Veteran Affairs

The policy and procedures for the ASoC have been detailed in prior VA Handbooks and in the ASoC Directive.¹ This article highlights the background, population served, and organizational structure of the ASoC by detailing the outcomes and accomplishments of this systems-based approach to longitudinal amputation care between 2009 and 2019. Four core areas of activities and accomplishments are highlighted: (1) learning organization creation; (2) trust in VA care; (3) system modernization; and (4) customer service. This analysis and description of the VA amputation care program serves as a model of amputation care that can be used in the civilian sector. There also is potential for the ASoC to serve as a care model example for other populations within the VA.

Organizational Structure

The ASoC is an integrated, national health care delivery system in which each VA medical center (VAMC) has a specific designation that reflects the level of expertise and accessibility across the system based on an individual veteran’s needs and the specific capabilities of each VAMC.^1-3 The organizational structure for the ASoC is similar to the Polytrauma System of Care in that facilities are divided into 4 tiers.^1,4

For the ASoC, the 4 tiers are Regional Amputation Centers (RAC) at 7 VAMCs, Polytrauma Amputation Network Sites (PANS) at 18 VAMCs, Amputation Clinic Teams (ACT) at 106 VAMCs, and Amputation Points of Contact (APoC) at 22 VAMCs. The RAC locations provide the highest level of specialized expertise in clinical care and prosthetic limb technology and have rehabilitation capabilities to manage the most complicated cases. Like the RAC facilities, PANS provide a full range of clinical and ancillary services to veterans within their catchment area and serve as referral locations for veterans with needs that are more complex. ACT sites have a core amputation specialty team that provides regular follow-up and address ongoing care needs. ACT sites may or may not have full ancillary services, such as surgical subspecialties or an in-house prosthetics laboratory. APoC facilities have at least 1 person on staff who serves as the point of contact for consultation, assessment, and referral of a veteran with an amputation to a facility capable of providing the level of services required.¹

The VA also places a high priority on both primary and secondary amputation prevention. The Preventing Amputations in Veterans Everywhere (PAVE) program and the ASoC coordinate efforts in order to address the prevention of an initial amputation, the rehabilitation of veterans who have had an amputation, and the prevention of a second amputation in those with an amputation.^1,5

Population Served

The ASoC serves veterans with limb loss regardless of the etiology. This includes care of individuals with complex limb trauma and those with other injuries or disease processes resulting in a high likelihood of requiring a limb amputation. In 2019, the VA provided care to 96,519 veterans with amputation, and about half (46,214) had at least 1 major limb amputation, which is defined as an amputation at or proximal to the wrist or ankle.⁶ The majority of veterans with amputation treated within the VA have limb loss resulting from disease processes, such as diabetes mellitus (DM) and peripheral vascular disease (PVD). Amputations caused by these diseases generally occur in the older veteran population and are associated with comorbidities, such as cardiovascular disease, hypertension, and end-stage renal disease. Veterans with amputation due to trauma, including conflict-related injuries, are commonly younger at the time of their amputation. Although the number of conflict-related amputations is small compared with the number of amputations associated with disease processes, both groups require high-quality, comprehensive, lifelong care.
