Aims: Secondary prevention of coronary heart disease is of utmost importance to facilitate people to achieve health outcomes and behaviours. This study was to investigate the effect of a nursing intervention based on Cox's interaction model of client health behaviour to improve health outcomes and behaviours of secondary prevention of coronary heart disease., Design: This study is a cluster randomised controlled trial., Methods: Participants were recruited between August and November 2019 in two community settings in Hengyang city, Hunan province, China. Participants in the intervention group received a nursing intervention based on Cox's interaction model of client health behaviour and routine health education, while those in the control group received routine health education only. The outcome variables included self-management, physical activity, medication compliance, anxiety, sexual knowledge, the ability to identify sexual health education needs, blood pressure, body mass index (BMI), and low-density lipoprotein cholesterol (LDL-C). The influential statistical tests applied to analyse the data included χ 2 tests and t tests., Results: Seventy-seven participants completed this study. Compared with the control group (n = 40), the intervention group (n = 37) showed statistically significant better health outcomes and behaviours regarding self-management, physical activity (except for high energy consumption), medication compliance, anxiety, sexual knowledge, the ability to identify sexual health education needs, systolic blood pressure, BMI, and LDL-C. However, there was no statistically significant difference in diastolic blood pressure and high energy consumption for physical activity., Conclusion: A well-developed nursing intervention based on Cox's interaction model of client health behaviour could successfully improve health outcomes and behaviours of secondary prevention of coronary heart disease. Such an intervention may be incorporated into community healthcare practice by nurses to improve patient care., Impact: This study provides a valuable insight to facilitate further development of effective nursing interventions to improve secondary prevention of coronary heart disease in community settings., (© 2021 John Wiley & Sons Ltd.)

Objective: This research aimed to determine how a 12-week PRECEDE-PROCEED model-based intervention affected fatigue in patients with coronary heart disease. Methods: This cluster randomized controlled trial recruited participants diagnosed with coronary heart disease at 2 community health centers in China. Participants in the control group (n = 36) received routine health education, whereas those in the intervention group (n = 38) were given a 12-week PRECEDE-PROCEED model-based intervention and routine health education. The intervention consisted of 6 training sessions on coronary heart disease, fatigue, fatigue management, self-management skills and social support. A primary outcome (fatigue) and 4 secondary outcomes (knowledge of fatigue, self-management, quality of life and body mass index) were assessed using the Fatigue Scale-14, Fatigue Cognitive Questionnaire for Patients with Coronary Heart Disease, Coronary Artery Disease Self-Management Scale, Chinese Cardiovascular Questionnaire of Quality of Life, and electronic weighing scale, respectively. Data were collected 3 times over 12 weeks. Results: Compared with the control group, the intervention group showed a statistically significant improvement in the level of fatigue (8.72 vs 7.06, P <.001), knowledge of fatigue (P <.001), self-management skills (P <.001), and quality of life (P <.001). However, there was no significant difference in body mass index between the 2 groups (P =.504). Conclusions: The findings suggest that a well-designed intervention based on the PRECEDE-PROCEED model could alleviate fatigue symptoms and increase knowledge of fatigue, self-management skills and quality of life in patients with coronary heart disease.
