User-relevant factors influencing the prosthesis use of persons with a transfemoral amputation or knee-disarticulation: A meta-synthesis of qualitative literature and focus group results

A qualitative meta-synthesis was conducted by searching five databases (last update January 20th 2022). Studies were considered eligible if they contained qualitative data about adult persons with a transfemoral amputation or knee-disarticulation with experience in using a prosthesis and focused on the users’ opinions. All eligible studies were independently screened by two reviewers.

The results sections of the included studies were entered in Atlas.ti software (v8) and coded using the framework approach. The quality of the included studies was assessed using the Critical Appraisal Skills Program (CASP) qualitative research checklist. Results of the meta-synthesis were validated with prosthesis users (n=8) in a focus group.

Results: Out of 5757 articles, 14 studies were included. An overview of seven themes (‘prosthesis related’; ‘rehabilitation, costs and prosthetist’; ‘mental’; ‘physical’; ‘social’; ‘activities and participation’ and ‘walking’) containing 84 factors was created. Ten factors were added during the focus group, resulting in an overview of 94 factors that may influence the prosthesis use of lower-limb prosthesis users.

Participants would like more user-involvement from the rehabilitation team. The development of a patient decision aid could help this process in the future. Conclusion: The large number of factors demonstrates that there is a great variety between prosthesis users and the factors that influence their prosthesis use.

Therefore, it is important to take individual preferences into account for the selection of a new prosthesis.
