Research on the factors that influence patients with colorectal cancer participating in the prevention and control of surgical site infection: Based on the extended theory of planned behaviour

BACKGROUND: The most common and severe type of nosocomial infection in patients with colorectal cancer is surgical site infection (SSI). Patient‐related factors are an important components of SSI. So it is necessary to participate in SSI prevention and control. It is important to identify the factors that influence patients' participation behaviour and to explore the mechanism of these effects. METHODS: A total of 580 patients with colorectal cancer completed relevant measures. Based on the extended theory of planned behaviour, a structural equation model was used to analyse the relationship among the influencing factors. RESULTS: The factors influencing participation of patients with colorectal cancer in SSI prevention and control were participation intention, participation ability, self‐efficacy, participation attitude, perceived medical staff support, trust in physicians and social support. The direct effect coefficients of participation intention, participation ability and physician trust on SSI prevention and control behaviour were 0.67, 0.21 and 0.11, respectively. Self‐efficacy, participation attitude, perceived medical staff support and social support indirectly affect participation behaviour through participation intention, and their effect values are 0.21, 0.11, 0.11 and 0.08, respectively. CONCLUSIONS: Based on the structural equation model developed in this study, targeted intervention measures should be implemented to mobilize the intention and enthusiasm of patients with colorectal cancer to participate in the prevention and control of SSI. PATIENT OR PUBLIC CONTRIBUTION: Patients or public contribute to spreading research findings, and promote broad participation in the implementation of policies or strategies.
