Unlike neuromotor prostheses, neurocognitive prostheses would sense or modulate neural function in order to physically reconstitute or augment cognitive processes such as , , language, and memory. No neurocognitive prostheses are currently available but the development of implantable neurocognitive brain-computer interfaces has been proposed to help treat conditions such as , , , , and . The recent field of concerns the development of technologies to augment human cognition. Scheduling devices such as remind users with memory impairments when to perform certain activities, such as visiting the doctor. Micro-prompting devices such as PEAT, and have been used to aid users with memory and executive function problems perform .
The last step in developing the cost matrix was to estimate total costs based on the three cost characteristics. The costs for transtibial and transfemoral levels were determined by assigning Medicare L-codes appropriate for prosthetic device type, limb-loss level, and functional level. The cost for each L-code was assigned using the median Medicare cost for the 50 states and the District of Columbia. Our cost reference was the "Fee Schedule Update for 2005 for Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS)" for noninstitutional providers .
Findings for veterans and servicemembers with bilateral upper-limb loss appear in . Only 50 percent of the Vietnam group ( = 6) use prostheses compared with 86 percent in the OIF/OEF group ( = 7). The OIF/OEF group use more than twice the number of prostheses; thus, a wide difference in 5-year average costs is observed: $90,065 compared with $333,445. More of the OIF/OEF group with bilateral limb loss use myoelectric devices (71%) than the Vietnam group (17%,
A Waterproof Prosthesis enables the amputee to use the prosthesis for tasks involving water, such as showering or swimming. Specially designed devices are available to allow for the use of flippers.
APC Prosthetics continues to lead the profession in prosthetic innovation. Our team is internationally recognized in specially designed and sporting prostheses in a broad range of activities including athletics, skiing, cycling, golf, weight lifting and more. If you are interested in competitive or social sporting activities, we are happy to provide contact details for the respective sports institutes and sporting bodies.
Based on our findings of modest cost increases when projecting prosthetic device use for the next 5, 10, and 20 years and lifetime for the number of veterans and servicemembers from Vietnam and OIF/OEF with traumatic limb loss, future prosthetic healthcare costs may be manageable for the VA and DOD facilities, providing available resources do not change dramatically. The lifetime cost projections do not account for significant changes in health policies or practices. Our study found higher costs associated with the OIF/OEF servicemembers, especially those with multiple limb loss, given the higher number of devices used and newer advanced technologies. The VA and other healthcare provider systems should be prepared for the increase in more advanced technologies and use of multiple prosthetic devices. This preparation for these advanced devices may include training for prosthetists and resources to support their use and maintenance. Future technologies such as the Defense Advanced Research Projects Agency (DARPA) arm [35-36] may dramatically increase future costs. Healthcare providers and policy makers will benefit from an understanding of current cost projections and a uniform approach for coverage of prosthetic and assistive devices for all veterans and servicemembers with major traumatic limb loss.
We compared our cost estimates with those published in the literature to the extent possible, given that our objective was to project future costs while published literature attempted to summarize current or prior costs. A study by Williams with a population similar to the Vietnam unilateral lower-limb group found costs that compare in order of magnitude to those we obtained for the unilateral lower-limb groups . Williams's analysis lacks a probabilistic framework (necessary measures of uncertainty, such as standard errors). Our review of the literature also identified a limited number of studies involving limb loss and projected costs of prosthetic devices with limited numbers of patients lacking representativeness; thus, these findings cannot be widely generalized [9,33].
prosthetic-device businesses to produce the remaining 95 percent of the devices. These private prosthetic providers are reimbursed by the VA at 5 to 10 percent below Medicare rates. We anticipated using the VA Decision Support System (DSS), a national automated management information system that integrates clinical and financial data systems for prosthetics , to perform a VA prosthetics cost accounting of veteran-specific prosthetic utilization and costs. The available DSS prosthetics data reviewed at several VA sites were not able to identify veteran-specific components and devices; therefore, this portion of the analysis was not pursued.
An initial objective for this study was to compare three costs scenarios for prosthetic device care: Medicare, VA in-house, and private practice. However, variations in costs and pricing practices made this impractical. Private- practice prosthetics costs are generally assumed to be billings to third-party insurers that reflect base Medicare costs and Medicare nonallowable services. Actual private-practice costs vary widely amongst practitioners and are not freely published. Certified prosthetists in VA medical center prosthetics laboratories make approximately 5 percent of veterans' prosthetic devices from components. The VA then contracts with nationally accredited local
Historical reimbursement practices for prosthetists and prosthetic devices have typically bundled costs for care, professional services, and devices. While most professional healthcare providers receive reimbursement based on professional services rendered, Medicare and private practice prosthetists receive bundled prosthetic reimbursement that covers all raw materials; purchased components; prosthetists' professional evaluation, fabrication, final fittings, and follow-up adjustments; material and labor overheads; general and administrative costs; and minimal profit. Medicare reimbursement values for prosthetic devices are readily available and accepted and therefore were used in this study.
Reported prosthetic and assistive device use is greater in the OIF/OEF group than the Vietnam group. For assistive device use, 50 percent of the Vietnam group and 57 percent of the OIF/OEF group reported use of a wheelchair . Of survey participants with unilateral upper-limb loss, 30 percent of the Vietnam group and 44 percent of the OIF/OEF group reported current use of assistive devices. For unilateral lower-limb loss, 62 percent of the Vietnam group and 69 percent of the OIF/OEF group currently use assistive devices to aid mobility .
We estimated 5-year, 10-year, 20-year, and lifetime prosthetic and assistive device costs for veterans and servicemembers with major traumatic limb loss associated with combat-theater injury. We found average projected 5-year costs for prosthetic devices and assistive devices for the OIF/OEF group were 2.8-fold to 3.8-fold higher than in the Vietnam group. Similarly, 10-year, 20-year, and lifetime costs ranged from 2.8-fold to 6.2-fold higher for the OIF/OEF group. There are several important reasons for these differences.
