Gender differences in prosthesis-related outcomes among veterans: Results of a national survey of U.S. veterans.

Abstract

Women with lower extremity amputations (LEAs) tend to have poorer prosthesis-related outcomes than men, although the literature is sparse. To our knowledge, there are no prior studies examining prosthesis-related outcomes of women veterans with LEAs. To examine gender differences (overall and by type of amputation) among veterans who underwent LEAs between 2005 and 2018, received care at the Veterans Health Administration (VHA) prior to undergoing amputation, and were prescribed a prosthesis. It was hypothesized that compared to men, women would report lower satisfaction with prosthetic services, poorer prosthesis fit, lower prosthesis satisfaction, less prosthesis use, and worse self-reported mobility. Furthermore, it was hypothesized that gender differences in outcomes would be more pronounced among individuals with transfemoral than among those with transtibial amputations. Cross-sectional survey. Linear regressions were used to assess overall gender differences in outcomes and gender differences based on type of amputation in a national sample of veterans. VHA medical centers. The sample consisted of 449 veterans who self-identified their gender (women = 165, men = 284) with transtibial (n = 236), transfemoral (n = 135), and bilateral LEAs (n = 68) including all amputation etiologies. Not applicable. The Orthotics and Prosthetics User's Survey, Trinity Amputation and Prosthesis Experiences Scale, and Prosthetic Limb Users Survey of Mobility-Short Form were used to assess satisfaction with prosthetic services, prosthesis fit, prosthesis satisfaction, prosthesis use, and self-reported mobility. Women had poorer self-reported mobility than men (d = -0.26, 95% confidence interval -0.49 to -0.02, p < .05); this difference was small. There were no statistically significant gender differences in satisfaction with prosthetic services, prosthesis fit, prosthesis satisfaction, daily hours of prosthesis use, or by amputation type. Contrary to the hypothesis, prosthesis-related outcomes were similar between men and women with LEAs. Minimal differences may in part be due to receiving care from the VHA's integrated Amputation System of Care.
