Brief Summary

Intermittent claudication is the most common symptom of peripheral arterial disease (PAD). The recommended therapy is supervised exercise therapy combined with lifestyle counselling, provided by a physiotherapist. Ideally, during the treatment process patients' values and preferences are incorporated with evidence-based knowledge; shared decision making (SDM). Evidence shows the use of SDM in daily practice is scarce. Therefore, personalized outcome forecasts which provide insight into an individual's personal prognosis (called KomPas) were implemented in 2020. Now, as a next step, KomPas is further developed into a guideline-based clinical decision support system. The result is called KomPas+, a tool which integrates the person-centered approach of KomPas with the guideline recommendations for the conservative treatment of people with intermittent claudication.The primary objective of this study is to evaluate the impact of implementing KomPas+ in the physiotherapeutic treatment of patients with intermittent claudication on functional walking distance and health-related quality of life. Secondary, the level of SDM and person-centeredness of physiotherapists using KomPas or KomPas+ will be assessed. Third, the implementation process will be evaluated.

Outcome Measures

Primary Outcomes (2)

  • Mean Change from Baseline in Functional walking distance (FWD) using a standardized treadmill test at 3 months, 6 months, 9 months and 12 months.

    The treadmill test is based on the graded Gardner-Skinner protocol. FWD is defined as the distance at which the patient would prefer to stop walking in daily life.

    Change from baseline at 3 months and 6 months

  • Mean Change from Baseline in Health-Related Quality of Life using the Vascular Quality of Life Questionnaire-6 (VascuQol-6) at 3 months, 6 months, 9 months and 12 months.

    The VascuQol-6 consists of six questions related to activities, symptom burden, pain, emotions and social consequences. The score ranges from 6 to 24, with a higher score representing a better quality of life.

    Change from baseline at 3 months and 6 months

Secondary Outcomes (2)

  • Level of Person-Centredness assessed by using a Patient-Administered Questionnaire at the initial consult with the patient with intermittent claudication in which treatment goals and treatment plan are discussed.

    During the initial consult with the patient with intermittent claudication in which treatment goals and treatment plan are discussed. This moment varies between the date of inclusion to three weeks after the date of inclusion.

  • Level of Shared Decision Making (SDM) assessed by scoring video-records of clinical consultations with the Observer Patient Involvement (OPTION) 5 scale at the initial consult with the patient in which treatment goals and treatment plan are discussed.

    During the initial consult with the patient with intermittent claudication in which treatment goals and treatment plan are discussed. This moment varies between the date of inclusion to three weeks after the date of inclusion.

Other Outcomes (2)

  • Perceived barriers and facilitators to (not) use KomPas+ in the physiotherapeutic treatment of patients with intermittent claudication using a qualitative assessment.

    Between six and twelve months after the start of the implementation of KomPas+

  • The degree of implementation of KomPas+ in terms of reach and demand measured by website logs (demand) and the use of KomPas+ (reach).

    After the 4-month inclusion period

Study Arms (2)

Control group: no access to KomPas+

OTHER

Therapists in the control group will not have access to KomPas+ and will continue to deliver usual care by using the KNGF guideline. They will also maintain access to KomPas. As with KomPas+, therapists are free to choose whether to use KomPas or not. The use of KomPas will also be encouraged.

Device: KomPas

Experimental group: access to KomPas+

EXPERIMENTAL

KomPas+ will be implemented within the experimental group. The use of KomPas+ in the physiotherapeutic treatment of patients with intermittent claudication will not be mandatory but will be encouraged through an implementation strategy. Therapists are free to choose whether to use it or not.

Device: KomPas+Device: KomPas

Interventions

KomPasDEVICE

KomPas is an online tool showing personalized outcome forecasts. These forecasts have been developed using real-world data of patients with intermittent claudication for physiotherapists in daily practice. The forecasts visualize the estimated outcome of supervised exercise therapy (walking distance and quality of life), for an individual patient with intermittent claudication. The information provided is based on patients similar to the individual patient from a large database. The actual outcome data of these similar patients are used to create an individual forecast. KomPas plots the estimated therapy outcome in time, thereby making personalized outcome forecasts. The forecasts are not used to direct the choices of treatment, but to motivate the patient, monitor the treatment process and to set realistic goals.
