Implementation of a personalized prediction model to support decisions during supervised exercise therapy for patients with Intermittent Claudication.

The recommended therapy for symptom relief in patients with Intermittent Claudication (IC) is, according to the KNGF and NHG guidelines, supervised exercise therapy (SET). Although SET is known to be effective in increasing walking distance, results can vary substantially between patients. A greater insight into an individual’s personal prognosis may support patients and providers in tailoring care to the needs and priorities of the individual, potentially resulting in better outcomes with less variation between individuals. To do so, ClaudicatioNet developed 'KomPas', a prediction tool which is able to visualize the expected outcome of SET for patients with IC, using a neighbors-based prediction approach. After a pilot and test phase of KomPas, ClaudicatioNet intends to implement KomPas among all their affiliated physical therapists (~2100) as part of a quality improvement project.
The primary aim of this study is to evaluate the effectiveness of KomPas as supporting tool to optimize personalized treatment, on the following outcomes: functional and maximal walking distance (assessed with a clinical test) and quality of life (assessed via questionnaire). The secondary aim of this study is to understand what factors (i.e., demand and interaction of therapists and patients with KomPas) mediated this (potential) effect.

We hypothesize that the use of KomPas at the start and during the SET will be associated with increased functional walking distance, maximal walking distance and the quality of life of patients with Intermittent Claudication. Moreover, we hypothesize that use of the KomPas will result in increased patient motivation and reducted drop-out rate.
