Brief Summary

Lower-limb amputation is associated with life-altering and life-limiting comorbidities. Currently, onus is on primary care providers to diagnose, educate, and refer patients for appropriate management. Recently our laboratory has found, however, that of adults post-amputation seen in an outpatient Limb Loss Clinic presenting with comorbidities, >50% are unaware they have signs of peripheral arterial disease and/or neuropathy. Lack of patient awareness and thus, inadequate comorbidity management, may contribute to suboptimal patient outcomes post-amputation. As a first step in this research line, the proposed project will help determine if comorbidity screening by prosthetists during routine care visits for patients post-amputation may enhance comorbidity awareness, increase patient satisfaction in prosthetic services, and reduce gratuitous prosthetic service utilization. During a follow-up visit, seventy patients following a unilateral lower-limb amputation will be randomized into either a standard-of-care group or a standard of-care plus group. The standard-of-care plus group will receive clinical screenings by a certified prosthetist for peripheral arterial disease, peripheral neuropathy, depression, and high-risk for persistent back pain; patient education on findings; and each participant's primary care provider will receive screening results. The long-term goal of this research is to determine if prosthetists can maximize their utility in an interdisciplinary care team, while enhancing patient outcomes post-amputation.

Study Groups

Standard-of-Care

Patient participants will receive routine standardized prosthetic follow-up care by a certified prosthetist, including evaluation of prosthesis use, prosthesis-enabled mobility, socket comfort and sock ply usage, falls, body anthropometrics, and functional mobility.

Group Type: OTHER

Standard-of-Care

Intervention Type: OTHER

Participants with a major unilateral transfemoral or transtibial amputation will undergo a standardized medical history and medication review, complete questionnaires evaluating prosthesis use, comfort, and mobility, receive a clinical examination of height, weight and limb circumference, and complete three performance-based mobility outcome measures.

Standard-of-Care + Clinical Screening

In addition to routine, standardized prosthetic follow-up care, patient participants will receive comorbidity screening for contralateral limb peripheral arterial disease, peripheral neuropathy, major depression, and greater than low risk for persistent low back pain. Participants will be educated on clinical screening findings, provided a copy of their screening results to share with their medical providers, and their results will be securely sent to their primary care provider.

Group Type: EXPERIMENTAL

Standard-of-Care

Intervention Type: OTHER

Participants with a major unilateral transfemoral or transtibial amputation will undergo a standardized medical history and medication review, complete questionnaires evaluating prosthesis use, comfort, and mobility, receive a clinical examination of height, weight and limb circumference, and complete three performance-based mobility outcome measures.

Clinical Screening

Intervention Type: OTHER

Participants will complete the following self-report questionnaires: (a) the Patient Health Questionnaire-9 item, which may suggest major depression and/or suicidal ideation; and (b) the STarT Back Screening Tool, a 6-item tool used to screen for greater than low-risk for persistent, bothersome and disabling low back pain. Prosthetists will perform palpation of the contralateral dorsalis pedis and posterior tibial pulses and note presence or absence, as an indicator of peripheral arterial disease. Prosthetists will evaluate protective sensation of the contralateral foot through Semmes-Weinstein monofilament assessment of the great toe, the 1st and 3rd metatarsal heads. The prosthetist will record the results in a letter that is sent to the patient's primary care provider, and provide a copy of the letter to the patient after discussing the results for each of the screens.
