Abstract
The aim of the study was to assess how the use of the International Classification of Functioning, Disability and Health (ICF) affects the formulation of a rehabilitation diagnosis.Materials and methods. Three patient groups were formed: the first group (n=130) did not use the ICF, the second (n=130) used the paper-based ICF, and the third (n=54) used the ICFreader software.Results. The use of ICF leads to more rehabilitative problems in the diagnosis that can be solved within the rehabilitation course. The highest number of clinically insignificant function domains was found in group 1. The number of activity and participation domains and environmental factor domains was significantly higher in groups two and three compared to group one. In group two the team spent between 8 and 15 minutes for the initial discussion per patient and between 2 and 5 minutes for repeated discussions.Conclusion. Applying the ICF in paper form and using the ICF-reader software leads to more rehabilitative problems in the rehabilitation diagnosis, which can be solved within the rehabilitation course.
