Study Overview
Brief Summary
The overall aim of the study is to evaluate a nurse-led intervention (person-centered follow up and health promotion) program in comparison to standard follow up for patients treated with surgical or endovascular revascularization of Intermittent Claudication.
Detailed Description
Specific Aims:
- To evaluate the effect of the intervention program on patient's adherence to medication (anticoagulant agents, antiplatelet agents and lipid-lowering agents), risk modification and surgical treatment outcomes
- To investigate the effect of the intervention program on patient reported outcomes
- To investigate the effect of the intervention program on patient reported experiences
- To investigate the long-term effect of the intervention program on mortality, cause of death, occurrence/recurrence of cardiovascular disease up to 10 years after the surgical/endovascular treatment
- To compare patient-reported adherence to medication and patient data registry adherence to medication
Hypothesis: Participants in the Intervention Group have better adherence to prescribed medication and a reduced risk for 10-year predicted coronary heart disease (CHD) compared to participants in the Control Group.
Study population:
Patients with Intermittent Claudication scheduled for revascularization, through open surgery or endovascular method, in Stockholm will be screened for inclusion. After informed consent, the participants will be randomized to either Intervention Group or Control Group. Those participants who couldn't receive revascularization after giving consent will be withdrawn from the study and counted as drop outs. Power analysis has showed a required sample size of 186 participants to detect a statistically significant increase in adherence to medication from 50% to 70% (power 0.80, significance value 0.05, two-sided). Expecting 10% drop-out we plan to recruit 210 participants.

Outcomes
Primary Outcomes
Adherence to medication
Time Frame: One year after surgical or endovascular treatment for Intermittent Claudication
Adherence to medication (anticoagulant agents, antiplatelet agents and lipid-lowering agents) according to the Swedish Prescribed Drug Registry (PDR). dispensed anticoagulant agents, antiplatelet agents (ATC-register B01A) and lipid-lowering agents (ATC-register C10). Those participants who have fetched both medications for the second refill after treatment will be considered adherent.
Secondary Outcomes
- Risk for 10-year predicted coronary heart disease (CHD)(One year after surgical or endovascular treatment for Intermittent Claudication)
