The status quo and influencing factors of clinical research nurses' participation in preoperative blood sampling in patients with pulmonary nodules.

Background: Under-recruitment in clinical trials has become a worldwide problem, and has many causes that need to be understood. Clinical Research Nurses (CRNs) provide a new research perspective.

Aim: To understand the current situation about the informed consent rate after the participation of CRNs and analyse the possible influencing factors.

Methods: This cross-sectional study was conducted at a hospital. A convenience sample was used to study patients with pulmonary nodules who underwent day surgery from March to May 2023. Patients first received information from doctors and a second session by CRNs was provided for those who initially were hesitant about the research. A questionnaire survey was conducted using an online survey platform to collect information.

Results: After education by doctors, 208 patients were hesitant and CRNs conducted a second education session, the CICARE model was used for communication. Following this session a further 161 patients were willing to participate. Finally, 374 patients were willing to participate. Related factors include age, education level and the attitude of self-assessed family members towards their participation in clinical projects.

Conclusions: CRNs' participation can improve patients' willingness to participate. It is crucial to pay attention to the role of CRNs and propose a new model of CRNs involvement in clinical research based on identifying factors.
