Prescription and repair rates of prosthetic limbs in the VA healthcare system: Implications for national prosthetic parity

摘要

Purpose: To quantify prescription and repair rates of prosthetic limbs in the Department of Veterans Affairs (VA) and explore differences by level, type, and age. Methods: Veterans (N = 32 440) with an initial prosthetic prescription between 2000 and 2010 were classified by amputation level and type. Annual rates of prescription and repair were calculated using person-time and compared by group. Results: Veterans with upper limb amputation had lower annual prescription and repair rates (0.28 and 0.21) compared with those with lower limb amputation (0.40 and 0.56). Myoelectric devices users had higher prescription rates. However, body-powered users had higher repair rates. Prescription and repair rates for microprocessor knee joints were higher than for fluid and friction devices. Veterans under 65 had 0.07 and 0.16 higher rates of prescription and repair than those over 65 (p < 0.0001). Conclusions: Because the VA is unconstrained by co-pays or caps, data on prosthetic prescription and repair can be used to estimate rates that might occur if national prosthetic parity laws were adopted. Given the rates found, it is likely that annual costs would exceed the typical annual and/or lifetime caps in most insurance plans. In states without prosthetic parity laws, such costs likely limit access to needed devices.
