Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Sample Approximately 60 patients with intermittent claudication diagnosed at the Department of vascular diseases at Skåne University hospital will be invited to participate. The participants should have access to a smartphone or tablet. For the randomization, envelopes will be prepared by a member of the research group and then mixed by another member of the group. After receiving informed consent, the participants are randomized by drawing one of the sealed envelopes with the information in which group they are included. The trial will have two arms; one group will test Lifepod®PAD (n=30) for three months and one control group (n=30) will receive secondary prevention as usual.
Data collection All participants will be invited to a separate appointment at the vascular open clinic at baseline and after three months and measured regarding weight, blood pressure, ABPI, six minutes walking test and pain. To calculate the estimate 10-year risk of manifesting clinical cardiovascular disease, the Framingham Risk Score will be used. Further, a questionnaire will be answered at baseline and after three months containing the instruments, VascuQoL-6, Health Education Impact Questionnaire (hei-Q) and Medication Adherence Report Scale-5.
Patients randomized to Lifepod®PAD will get access and be introduced to the Lifepod®PAD support system software. Patients in the control group will receive usual care meaning advice about lifestyle changes and medication from the physician at the visit in the vascular open clinic.
After completing the intervention, a random number of patients who have tested Lifepod®PAD will be invited to take part in focus group interviews to discuss their experiences of using the devices. The interviews will be analyzed by thematic content analysis.
The intervention Lifepod®PAD is a web-based application designed to support adherence to lifestyle advice and medication and is built as a two-side system. One side is the patient interface, the web-based application, accessible through a smartphone or tablet. The patients can log information about their lifestyle, symptoms and medication and review their data in relation to recommended targets. They get positive feedback, recommendations about healthy behaviours and receive notifications as short messages depending on their individual health status. The other side is the medical interface managed by the health care professionals. All information the patient is reporting into the app can be accessed by the treating nurse and the system ranks the patients, thus gives high priority to patients who have the greatest needs.
Analysis Primary outcome will be pain free walking distance according to six minutes walking test at baseline and after three months. Secondary outcomes are quality of life, illness perception, self-efficacy, adherence to medical treatment, blood pressure and ABPI. Acceptability, delivery of the intervention, expected sample size and effect size, procedure of randomization and follow-ups will be further evaluated.
Descriptive statistics will be used to describe the study sample. T-tests will be used to compare groups and chi-square tests will be used to study differences in proportions. Effect size will be calculated to estimate the magnitude of the potential effects and constitute a base for power calculation and sample size in a full-size RCT. The outcome will be used to design a main multicenter randomized trial Ethical considerations Verbal and written information about the purpose of the studies will be given and a written informed consent will be obtained in all studies. Additionally, they will be informed that participating is voluntary and the can withdraw at any time without providing any reason. Approval for the project are provided by the Swedish Regional Ethical Review Board (Dnr 2017/609)

Application-based support system Lifepod®PAD
Patients in the experimental group will be introduced to and use Lifepod®PAD, a web-based application designed to support adherence to lifestyle advice and medication for three months. Lifepod®PAD is built as a two-side system. One side is the patient interface, the web-based application, accessible through a smartphone or tablet. The patients can log information about their lifestyle, symptoms and medication and review their data in relation to recommended targets. They get positive feedback, recommendations about healthy behaviours and receive notifications as short messages depending on their individual health status. The other side is the medical interface managed by the health care professionals. All information the patient is reporting into the app can be accessed by the treating nurse and the system ranks the patients, thus gives high priority to patients who have the greatest needs.
Application-based support system
All participants (experimental and control group) will be invited to a separate appointment at the vascular open clinic at baseline and after three months and measured regarding weight, blood pressure, Ankle Brachial Pressure Index, six minutes walking test and pain. To calculate the estimate 10-year risk of manifesting clinical cardiovascular disease, the Framingham Risk Score will be used. Further, a questionnaire will be answered at baseline and after three months containing the instruments, VascuQoL-6, Health Education Impact Questionnaire and Medication Adherence Report Scale-5.
Life style advice according to usual practice
Patients in the control group will receive usual care meaning advice about lifestyle changes and medication from the physician at the visit in the vascular open clinic.
