Abstract: Objective: To investigate the current status and explore the influencing factors of self-management behavior in cancer patients with implantable venous access ports, providing reference for improving the self-management behavior. Methods: From October 2022 to October 2023, a convenience sample of 812 cancer patients with implantable venous access ports from 19 hospitals in 8 provinces or autonomous regions was investigated by the tumor patients with implantable venous access ports self-management behavior assessment scale. Multiple linear regression analysis was used to identify influencing factors. Results: The score of self-management behavior for implantable venous access ports was 122.90±19.16, with the lowest scoring dimension being "access to maintenance information" (scoring rate was 71.9%). The regression results revealed that the factors influencing self-management behavior in cancer patients with implantable venous access ports included primary disease diagnosis, education level, marital status, family residence, duration of placement, involvement in the selection of port placement site, concerns about damage to the port, impact of the port on social activities, perception of the benefits to port, and satisfaction with the port (P<0.05). Conclusion: Overall, cancer patients has a relatively high level of self-management behavior for implantable venous access ports, but there is still room for improvement in terms of access to maintenance information. Healthcare providers should encourage patient participate in implanting decision-making, enhance patients' awareness of the benefits of ports and improve their satisfaction, so as to promote their self-management behavior.
