Focusing research efforts on the unique needs of women prosthesis users

Sex and gender differences in upper extremity prosthesis rejection: A review of literature

Prosthesis rejection is a significant barrier to rehabilitation of persons with upper limb difference. Many individual factors can affect device rejection, including a person's sex or gender. The objective of this narrative review was to explore the reported differences between the sexes and genders in upper limb prosthesis rejection. This review considered peer-reviewed, published research studies in which the study population were adults (aged 18 and older) who had unilateral or bilateral limb difference (any level) of any etiology with current, past, or no history of prosthetic device usage. Using identified keywords, index terms, and a peer-reviewed search filter, the literature was searched in MEDLINE, Embase, and PsycInfo. The reasons for rejection, disuse, or abandonment of prosthetic devices were extracted, with the focus on reported differences between sex and genders. After searching, 29 articles were selected for full-text review and 15 were included. Only 5 of 15 articles examined differences between the sexes. Women tend to reject upper extremity prostheses more than men both before and after being fit with a device; device characteristics, such as weight and cosmesis, do not appear to be appropriately designed for women; and there may not be adequate consideration of the goals for women with limb difference(s). There is inadequate reporting of sex and gender in the literature on prosthesis rejection; future studies should report and explore these factors to determine whether the needs of the full population with limb loss are being met.

The effect of depression on prosthesis prescription in men and women who have undergone a lower limb amputation

PURPOSE

To determine gender disparities and potential factors that modify prosthesis prescription practices in veteran patients who have undergone their first major unilateral amputation due to diabetes or peripheral arterial disease.

MATERIALS AND METHODS

A retrospective cohort study using the VA Corporate Data Warehouse to compare prosthesis prescription rates and time to prescription between men and women veterans. The primary exposure was gender. The primary outcome was a qualifying prosthesis prescription within 12 months of the incident amputation. The secondary outcome was time to prosthesis prescription. Multiple logistic and linear regression was used to control for potential confounders and identify potential effect modification.

RESULTS

2,862 individuals met study criteria, with 1690 (60%) prescribed a qualifying prosthesis. Men were more likely to receive a prosthesis prescription than women (59% versus 45%, respectively; p = 0.03). This difference was observed primarily among those with a diagnosis of major depressive disorder. In this subgroup, the odds of men receiving a prosthesis over women was over 3 times (adjusted odds ratio = 3.3; 95% Confidence Interval, 1.5, 7.4). Men had a mean shorter time to prescription compared to women (112 ± 72 versus 136 ± 79 days, respectively, p = 0.08).

Depression in women negatively impacts their prosthesis prescription rates and time to prescription compared to men. This disparity may have significant impacts on future function and quality of life.Implications for RehabilitationThis study found that men more commonly received a prosthesis prescription and received it earlier than women.This disparity was most extreme among women who had been diagnosed with major depressive disorder.Providers should identify at risk patients early and consider targeted interventions to address depression during the preoperative and immediate postoperative phases.Future research should continue to work to identify gender-specific needs that exacerbate disparity.

Footwear limitations in women prosthesis users relate to more than preference

BACKGROUND

The option to wear desired footwear may be an important part of community reintegration after lower-limb amputation.

OBJECTIVES

This study explored outcomes related to footwear, health, and participation in women Veterans with lower-limb amputation.

METHODS

A cross-sectional questionnaire was mailed to all women Veterans age 18-82 years with major lower-limb amputation(s) who had received prosthetics services in the US Department of Veterans Affairs (N = 538). The questionnaire assessed Perceived Challenges (including clothing limitations, prosthetic foot limitations [width, height, and shape], and shoe avoidance for safety concerns), type of footwear used and preference, and included subscales from the Patient-Reported Outcome Measurement Information System, Amputee Body Image Scale Prosthetic Limb Users' Survey of Mobility, Community Participation Index, Activities-Specific Balance Confidence Scale, and Prosthesis Evaluation Questionnaire. Bivariate correlations examined relationships between a composite measure of Perceived Challenges and patient-reported outcomes.

RESULTS

One hundred questionnaires were returned (18.6% response rate; 3 excluded for limited prosthesis use). The Perceived Challenges score was significantly correlated with scores for the Amputee Body Image Scale-Revised (r = 0.24, p = 0.019), Patient-Reported Outcome Measurement Information System (ability to participate: r = -0.25, p = 0.014), Prosthesis Evaluation Questionnaire (utility: r = -0.32, p = 0.001, appearance: r = -0.48, p < 0.001), Activities-Specific Balance Confidence Scale (r = -0.20, p = 0.046), and Prosthetic Limb Users' Survey of Mobility (r = -0.21, p = 0.036), but not depression or anxiety.

CONCLUSIONS

Women who have greater issues with how their prosthesis affects the shoes and clothing they can wear also have poorer body image, reduced functional capabilities, and lower reported participation in activities. Improved prosthetic foot design may help to improve social participation and other important outcomes for women prosthesis users.

Voices of Women Veterans with Lower Limb Prostheses: a Qualitative Study

BACKGROUND

Women Veterans with amputation are a group with unique needs whose numbers have grown over the last 5 years, accounting for nearly 3% of all Veterans with amputation in 2019. Although identified as a national priority by the Veterans Health Administration, the needs of this population have remained largely underrepresented in amputation research.

OBJECTIVE

To describe the experiences of women Veterans with lower extremity amputation (LEA) related to prosthetic care provision and devices.

DESIGN

National qualitative study using semi-structured individual interviews.

PARTICIPANTS

Thirty women Veterans with LEA who had been prescribed a prosthesis at least 12 months prior.

APPROACH

Inductive content analysis.

KEY RESULTS

Four key themes emerged: (1) a sense of "feeling invisible" and lacking a connection with other women Veterans with amputation; (2) the desire for prosthetic devices that meet their biological and social needs; (3) the need for individualized assessment and a prosthetic limb prescription process that is tailored to women Veterans; the current process was often perceived as biased and either dismissive of women's concerns or failing to adequately solicit them; and (4) the desire for prosthetists who listen to and understand women's needs.

CONCLUSIONS

Women Veterans with LEA articulated themes reminiscent of those previously reported by male Veterans with LEA, such as the importance of prostheses and the central role of the provider-patient relationship. However, they also articulated unique needs that could translate into specific strategies to improve prosthetic care, such as integrating formal opportunities for social support and peer interaction for women Veterans with LEA, advocating for administrative changes and research efforts to expand available prosthetic component options, and ensuring that clinical interactions are gender-sensitive and free of bias.
