OASIS Series

The Outcomes ASsessment and DISsemination (OASIS) series* compares the effectiveness of a variety of orthotic and prosthetic components across different patient groups to ultimately impact and enhance patient outcomes.

*Only the first study is published at this time.

The IMPACT series analyzes data on adults with lower limb amputation (n=510) obtained from a nationally representative administrative claims database (Watson) to find and interpret useful patterns.

About Watson: The Watson database is a large US private sector health claims database containing de-identified records representing approximately 25% of all commercial claims aggregated into one database with patient-level enrollment history, medical, and pharmacy commercials claims nationwide.

Mobility Analysis of AmpuTees (MAAT) Series

The prevalence of lower limb amputations in the United States continues to rise with a projected population of 3.6 million amputees by 2050, up from 1.6 million in 2005.1 Accompanying the rise in patients is a shift in healthcare policies that place increased emphasis on patient-centered outcomes as they relate to prosthetic mobility.2,3 While prosthetic rehabilitation has traditionally focused on restoring functional mobility, there is now a need to go beyond that and better understand the impact of improved mobility holistically.

MAAT is comprised of six separate landmark studies that represent one of the largest multicenter retrospective analyses of mobility among users of lower limb prostheses. The series seeks to clarify the concept of prosthetic mobility as it relates to such considerations as satisfaction, quality of life, comorbid health conditions, and prosthetic component choices.
