The overarching hypothesis of this work is that the lack of shared decision making (SDM) for prosthetic design and failure to match patient expectations with a prosthetic design plan result in poor health outcomes for patients with LLA. Shared decision making (SDM) is where clinicians and patients share the best available evidence for comparing options in order to achieve informed preferences for making health decisions. A patient's involvement in their health care process is known to affect their satisfaction, adherence to care programs, and health outcomes. Clinical decision aids (DAs) support patients in SDM and making informed health decisions, by providing information on the available options and associated outcomes. DAs are intended to help patients clarify their values associated with the options and potential outcomes, to create a platform for communication with healthcare providers. DAs have been shown to improve patient knowledge and realistic expectations for given health options. This project aims to examine how to better align patient and clinician values and expectations by developing a DA for prosthetic design decision options, to support SDM between patients receiving their first prosthesis and prosthetic care providers. This proposal will be guided by the International Patient Decision Aids Standards (IPDAS). Aim 1: Qualitatively define the key determinants and decisional needs of new prosthetic patients (n=14) and prosthetic care providers (n=20- 24) during prosthetic design, via semi structured interviews with patient participants and focus groups with prosthetist participants. Expected Result 1.1: Key determinants and decisional needs for prosthetic design will be defined using content analysis guided by the Ottawa Decision Support framework9 for patients making health decisions, and the Model for Shared Decision Making in Clinical Practice. Expected Result 1.2: Key stakeholders who contribute directly to prosthetic design decisions (e.g., patients with LLA, prosthetists, physicians, caregivers, close friends or family members) will be identified via purposive sampling, to inform the target end users of a DA prototype. Aim 2: Synthesize the evidence for prosthetic design decision options to develop a DA prototype. Expected Result 2.1: Via systematic literature review, a DA prototype will be developed from the evidence on prosthetic design decision options associated with decisional needs identified in Aim 1. Aim 3: Assess the DA prototype's accuracy, comprehensibility, and usability through alpha testing with an expert working group of patients with LLA and prosthetic care providers. Expected Result 3.1: Quantitative results from a Likert scale measurement of the DA prototype's accuracy, comprehensibility and usability will inform revisions to the DA prior to use in a pilot clinical trial. Expected Result 3.2: Qualitative feedback on the DA prototype's accuracy, comprehensibility, and usability will inform directed iterative revision for the DA prototype and implementation methods for use in a pilot clinical trial.
