Self-management Interventions to Reduce Cardiovascular Risks in Breast Cancer Survivors

The goal of this proposed single-group pre-post pilot study is to assess the feasibility and acceptability of the codesigned Nurse-led and GP-supported self-management interventions (NGPS) to reduce cardiovascular risks in breast cancer survivors with cardiovascular diseases. The study will also assess the preliminary effects of the NGPS intervention on various outcomes, such as behavioural, physiological, psychological, and healthcare usage. These outcomes will be measured at three time points, which include the baseline measurement at recruitment (T1-week 1), right after the four weeks' intervention (T2-week 4), and eight weeks after completing the intervention (T3-week 12). The study will be conducted in the primary care centres, and the self-management interventions are behavioural change interventions such as physical activity, diet modifications, tobacco cessation, weight management, eliminating or reducing alcohol consumption, and mind-body exercises such as yoga. The main questions it aims to answer are: 1. What are the recruitment, retention, attrition, and completion rates of participants and potential adverse effects related to the NGPS interventions for the participants throughout the pilot study? 2. What are the adherence rates of the NGPS protocol, participants' response and completion rates of the study instruments during the data collection period of the pilot study? 3. Do this pilot study results indicate any significant differences in cardiovascular health outcomes (e.g., BMI and blood pressure), physical activity, dietary intake, QoL, self-efficacy, anxiety and depression between and across different time points (Baseline (T1), post-intervention (T2), follow-up (T3))?
