5, 6, 11, 15, 16, 17 and 18 Weak evidence supports an association between psychological factors, self-efficacy, motivation and outcome.5 Prosthetic outcome has also been associated with postoperative factors including high-level or multiple limb amputation, postoperative complications, wound healing, oedema, contractures, pain, delay to prosthesis, falls, energy cost of gait, and functional factors.5, 6, 9, 19, 20, 21, 22, 23, 24, 25 and 26 Prosthetic outcome is therefore multifactorial and complex. To date, no studies have examined

the factors that in combination are able to identify individuals at risk of prosthetic non-use following discharge from rehabilitation. A methodological approach of developing clinical prediction Selleck Erastin rules has been used in similar prognostic studies (eg, ankle fractures, neck pain)27 and 28 and is yet to be established in the area of lower limb amputation. Clinical prediction rules are tools that assist clinicians

to make evidence-based decisions and assign patients to interventions and targeted models of http://www.selleckchem.com/ferroptosis.htmll care using a parsimonious subset of predictor variables.27, 28, 29 and 30 If clinical prediction rules could be generated to accurately identify individuals at risk of early prosthetic non-use, then rehabilitation teams could intervene with targeted models of care and prosthetic innovations to optimise functional outcome and allocation of healthcare resources. Therefore the research questions for this study were: 1. Can rules be developed to predict the risk of non-use of prostheses by people with lower limb amputation following discharge from rehabilitation? Inclusion criteria were: at least one recent major lower limb amputation (ie, transtibial level or above); community dwelling and ambulant prior to amputation; Medicare Functional Classification K-level 1 to 4 (from Gailey et al24); and had participated in and been discharged from prosthetic rehabilitation at Royal Perth Hospital, which is the state centre for amputee rehabilitation. Royal Perth Hospital rehabilitates 85% of all individuals with lower limb amputation

in Western Australia.3 Individuals with multiple limb amputations were included, as this was important for validity Rutecarpine of the clinical prediction rules. Participants were excluded if they were unable to communicate, did not consent, or were not prosthetic candidates (ie, K-level 0) as assessed collaboratively by the rehabilitation physician and senior physiotherapist. Reasons for K-level 0 categorisation included comorbidities, cognitive impairment, high-level amputation, multiple limb amputation, remaining limb pathology, increased body weight, mental health issues, poor motivation, no social support, poor premorbid mobility or falls history. These participants were monitored through amputee outpatient clinic but remained at K-level 0.
