ObjectiveTo investigate the factors related to the abandonment of upper limb prostheses. MethodsA total of 138 amputees fitting with upper limb prostheses at Guangdong Work Injury Rehabilitation Hospital from January 1st, 2016 to December 31st, 2022 were reviewed through case data, and those whose Functional Independence Measure scores improved after fitting were selected. A total of 126 amputees were investigated through telephone or WeChat with a questionnaire. The questionnaire was designed based on Trinity Amputation and Prosthesis Experience Scale-Revised, short form of Health Survey (SF-36) and World Health Organization Quality of Life Scale-Brief, and the items that may lead to the abandonment of upper limb prostheses were summarized in four factors: amputee, prosthetic fitting, prosthetic training, and environment and social policy. ResultsThe overall abandonment rate was 23.0% (29/126). There was significant difference between the the amputee abandonment or using prostheses in educational levels, amputation levels and residual limb condition (χ² > 6.808, P < 0.05); types of prostheses, whether functional prostheses, expectation for prosthesis, comfort of the prostheses, convenience of putting on and taking off, sensitivity of manipulation, weight of the prostheses, satisfaction with the appearance, skill levels of the prosthetist, the satisfaction after prosthesis installation and satisfaction with the prostheses in use (χ² > 13.083, P < 0.05); training levels before prosthesis assembly, the mastery of functional prostheses three months after prosthesis installation, training for activities of daily living, simulated training for vocation (χ² > 6.520, P < 0.05); willingness to participate in social activities with prostheses, attitude of other persons towards their prostheses, support of family members, work status, familiarity with the policies of welfare, and the current physical condition (χ² > 13.152, P < 0.01). ConclusionFactors of amputee, prosthetic fitting, prosthetic training, and environment and social policy may relate to the abandonment of upper limb prostheses, which are needed to improve in an accurate way.
