Patient Related Outcomes After Receiving a Person Centred Nurse Led Follow Up Programme Among Patients Undergoing Revascularisation for Intermittent Claudication: A Secondary Analysis of a Randomised Clinical Trial

Abstract

Objective: The aim was to evaluate the effect of a person centred nurse led follow up programme on health related quality of life (HRQoL), health literacy, and general self efficacy compared with standard care for patients undergoing revascularisation for intermittent claudication (IC), and to describe factors associated with HRQoL one year after revascularisation.

Methods: This was a secondary analysis of a randomised controlled trial. Patients with IC scheduled for revascularisation at two vascular surgery centres in Sweden between 2016 and 2018 were randomised to intervention or control. During the first year after surgery, the intervention group received a person centred follow up programme with three visits and two telephone calls with a vascular nurse, while the control group received standard follow up with two visits to a vascular surgeon or vascular nurse. Outcomes were HRQoL measured by VascuQol-6, health literacy, and general self efficacy measured by validated questionnaires.

Results: Overall, 214 patients were included in the trial; this secondary analysis comprised 183 patients who completed the questionnaires. One year after revascularisation, HRQoL had improved with a mean increase in VascuQol-6 of 7.0 scale steps (95% CI 5.9 - 8.0) for the intervention and 6.0 scale steps (95% CI 4.9 - 7.0) for the control group; the difference between the groups was not significant (p = .18). In an adjusted regression analysis, the intervention was associated with higher VascuQoL-6 (2.0 scale steps, 95% CI 0.08 - 3.93). There was no significant difference between the groups regarding health literacy or general self efficacy. The prevalence of insufficient health literacy among all participants was 38.7% (46/119) at baseline and 43.2% (51/118) at one year.

Conclusion: In this study, a person centred, nurse led follow up programme had no significant impact on HRQoL, health literacy, or general self efficacy among patients undergoing revascularisation for IC. The prevalence of insufficient health literacy was high and should be addressed by healthcare givers and researchers.
