Member Research Initiative Highlight: Hanger
The American Journal of Physical Medicine and Rehabilitation recently published a study suggesting that early delivery of a prosthesis following amputation is associated with up to a 25 percent reduction in overall direct healthcare costs.
In a recent webinar, a panel of experts reviewed the study’s findings while assessing their impact on patients’ day-to-day lives, and several questions arose as part of that discussion. In this webinar, study co-author and Hanger’s Director, Clinical Research Shane Wurdeman, PhD, CP, FAAOP (D) answers those questions and provides further insight into the importance of these findings to the O&P profession.
RAND Value Simulation Study
As part of the Prosthetics 2020 Initiative, the RAND Corporation conducted a value simulation, the “Economic Value of Advanced Transfemoral Prosthetics” where they simulated the differential clinical outcomes and costs of microprocessor-controlled knees (MPKs) compared with non-MPKs (NMPKs), and conducted a literature review of the clinical and economic impacts of prosthetic knees, convened technical expert panel meetings, and implemented a simulation model over a ten-year time period for unilateral transfemoral Medicare amputees with Medicare Functional Classification Levels of 3 and 4.
Data Regarding Provision and Utilization of Orthotic and Prosthetic Services
AOPA, through its partnership with the research and data firm Dobson DaVanzo & Associates, LLC, has obtained a plethora of data specific to the provision and utilization of Orthotic & Prosthetic services. This data, which is only available to current AOPA members, tells a compelling story about the type of O&P services Medicare patients are receiving as well as what provider categories (O&P, physicians, DME suppliers, pharmacies, etc.) are providing them. It also provides valuable information regarding patients who initially receive off the shelf (OTS) items who later require custom fitted or custom fabricated items. In addition, the compendium contains valuable information regarding the cost effectiveness of O&P services relative to their effect on overall healthcare expenditures for Medicare patients.

Medicare Spending on Prosthetics from 2010-2014
Overall spending on prosthetics has decreased 15%, while spending on outdated technology has actually decreased.
