Improving shared decision-making for prosthetic care: A qualitative needs assessment of prosthetists and new lower-limb prosthesis users

"I was angry that I fell" all the way to "if I fall, I fall": a qualitative study of the spectrum of behavioral fall risk factors for veterans with dysvascular lower-limb amputation

PURPOSE

To explore behavioral risk factors contributing to fall and near-fall scenarios for Veterans with dysvascular lower-limb amputation.

MATERIALS AND METHODS

Participants were a convenience sample of Veterans with unilateral dysvascular lower-limb amputation, receiving care at a single Veterans Administration Regional Amputation Center, who participated in an interview (12/2021-04/2023). We used phenomenological research and directed content analysis to explore participant perspectives on fall scenarios. Two frameworks informed a priori codes (The Health Action Process Approach, and the Falls-Type Classification Framework); however, analysis was also inductive, with additional codes emerging. Following an independent and iterative coding process, codes were categorized, and patterns identified to create final themes.

RESULTS

Twenty-one veterans completed interviews. Five themes were identified that were salient across a behavioral fall risk factor spectrum from low to high: self-efficacy, trust in the prosthesis, dual-task awareness, participation, and emotional regulation, and one theme pertaining to context surrounding the index fall.

CONCLUSION

Different levels of behavioral fall risk factors exist for Veterans with dysvascular lower-limb amputation. Understanding individuals' perceptions of these behavioral risk factors is important as a first step in developing comprehensive fall-risk management rehabilitation interventions for Veterans with amputation.

Development and alpha testing of a patient shared decision aid for prosthesis design for new lower limb prosthesis users

BACKGROUND

After lower limb amputation, several prosthesis design options exist. However, prosthesis design decisions do not always reflect a prosthesis user's needs, values, and preferences.

OBJECTIVE

To develop a patient decision aid (PDA) prototype for prosthetists and new prosthesis users facing prosthesis design decisions after lower limb amputation, and to assess its usability, accuracy, and comprehensibility.

STUDY DESIGN

Exploratory mixed methods.

METHODS

PDA development was informed by a qualitative needs assessment and guided by the International Patient Decision Aid Standards. The PDA was evaluated by steering groups of experienced prosthesis users and prosthetic professionals (prosthetists and researchers) to test usability, accuracy, and comprehensibility through focus groups, individual interviews, and rating on a Likert scale ranging from 1 to 10.

RESULTS

The resulting PDA included 6 sections: (1) Amputation and Early Recovery, (2) Communication, (3) Values, (4) Prosthesis Design, (5) Preferences, and (6) Prosthetic Journey. Usability, accuracy, and comprehensibility were rated as 9.2, 9.6, and 9.6, respectively, by prosthetic professionals, and 9.4, 9.6, and 9.6, respectively, by prosthesis users.

DISCUSSION

The PDA incorporated guidance by relevant stakeholders and was rated favorably, emphasizing a need for shared decision-making support in prosthesis design. One challenge was determining the amount of information in the PDA, highlighting the diversity in end users' informational needs. Future iterations of the PDA should undergo beta testing in clinical settings.

CONCLUSIONS

A standardized, iterative method was used to develop a PDA for new lower limb prosthesis users and prosthetists when considering prosthesis design decisions. The PDA was considered useable, accurate, and comprehensible.

Development of an Education Material Targeting Patients Undergoing Lower Extremity Amputation due to Severe Limb Ischemia-A Qualitative Study

INTRODUCTION

Critical limb-threatening ischemia (CLTI) is associated with a high risk of amputation, yet patients undergoing amputation due to CLTI have little knowledge of the amputation process and the rehabilitation that awaits. The aim of the present study was to develop and validate information material for patients undergoing amputation.

METHODS

Nine participants were included in the study. Two focus group interviews were performed with seven patients who had undergone lower extremity amputation due to CLTI within the past 2 y. Additionally, two individual interviews were carried out. A semistructured interview guide was used, and the interviews were transcribed verbatim and analysed using qualitative content analysis with a deductive approach.

RESULTS

Three themes were identified as essential for the design of the written information: Perspectives on design and formatting, Providing information to enhance participation in care, and Accessibility to information and support. The prototyped information leaflet was perceived as acceptable, useable, relevant, and comprehensible by the participants.

CONCLUSIONS

For patients to actively engage in their care, it is vital that their information needs are met and that they are provided with psychosocial support when needed. Written and oral information should be provided by a trusted healthcare professional.

Advances in prosthetic technology: a perspective on ethical considerations for development and clinical translation

Technological advancements of prostheses in recent years, such as haptic feedback, active power, and machine learning for prosthetic control, have opened new doors for improved functioning, satisfaction, and overall quality of life. However, little attention has been paid to ethical considerations surrounding the development and translation of prosthetic technologies into clinical practice. This article, based on current literature, presents perspectives surrounding ethical considerations from the authors' multidisciplinary views as prosthetists (HG, AM, CLM, MGF), as well as combined research experience working directly with people using prostheses (AM, CLM, MGF), wearable technologies for rehabilitation (MGF, BN), machine learning and artificial intelligence (BN, KKQ), and ethics of advanced technologies (KKQ). The target audience for this article includes developers, manufacturers, and researchers of prosthetic devices and related technology. We present several ethical considerations for current advances in prosthetic technology, as well as topics for future research, that may inform product and policy decisions and positively influence the lives of those who can benefit from advances in prosthetic technology.
