SUMMARY:

In the preoperative period of coronary artery bypass grafting (CABG), anxiety is a
common response that may hinder effective communication between patients and
healthcare professionals, while also contributing to surgical delays, prolonged
hospitalization, and postoperative complications. In this context, health education
supported by technological resources represents a non-pharmacological strategy capable
of reducing anxiety by facilitating communication and bringing healthcare information
closer to the patient's reality through a care-educational technology. Therefore, this study
aimed to evaluate the effect of a care-educational technology on anxiety levels and
knowledge acquisition among patients in the preoperative period of coronary artery
bypass grafting. This methodological study was conducted in three stages. First, a scoping
review was carried out in 2024 following the Joanna Briggs Institute guidelines to identify
scientific evidence regarding preoperative education and to support the development of a
structured script. Subsequently, the care-educational technology was developed and
underwent content validation. Following validation, the script was transformed into an
educational video by a private company, which served as the educational technology
evaluated in this study. The technology was further subjected to semantic validation by
the target audience, consisting of patients awaiting CABG in the cardiology ward of the
University Hospital Onofre Lopes (HUOL). This phase was conducted during the second
semester of 2025. Both content and semantic validation followed the criteria proposed by
Pasquali (2010) and employed the Delphi technique, adopting an acceptable agreement

index greater than 0.80. Concurrently, the technology was evaluated through an open-
label, parallel-group randomized clinical trial conducted during the second semester of

2025. Participants allocated to the control group received standard verbal preoperative
education, whereas those in the experimental group received the care-educational

technology intervention. In both groups, anxiety levels were assessed using the State-
Trait Anxiety Inventory (STAI), and knowledge regarding cardiac surgery was measured

using a cardiac surgery knowledge assessment scale before and after the interventions.

Eligible participants were adults aged 18 years or older, of either sex, awaiting coronary
artery bypass grafting. Patients who had previously undergone cardiac surgery or who
were unable to understand the educational content were excluded. The study received
ethical approval from the Research Ethics Committee of the Federal University of Rio
Grande do Norte (CAAE: 82212724.4.0000.5537) and was registered in the Brazilian
Registry of Clinical Trials (ReBEC) under registration number RBR-5g3jvz7. The
scoping review identified and analyzed 12 studies, resulting in a comprehensive list of
essential preoperative guidelines to be provided to patients undergoing cardiac surgery.
Content validation involved seven expert judges and was completed after two Delphi
rounds, achieving a final agreement index of 0.93. Semantic validation was conducted
with 20 patients in a single round and obtained an agreement index of 0.97, with no
recommendations for modifications, confirming the adequacy of the technology for
application in the randomized clinical trial. The clinical trial included 52 participants
equally allocated between the control and experimental groups. Both groups
demonstrated significant reductions in anxiety levels and significant increases in
knowledge following the interventions (p < 0.001). Although no statistically significant
differences were observed between groups, the care-educational technology proved to be
an effective and promising tool for implementation in health education focused on
patient-centered care. The educational technology improved communication by
standardizing and clarifying the information provided during preoperative education,
contributing to greater stability throughout the surgical process and enhancing patient
self-care and engagement in the care plan. The reduction of anxiety and improvement of
knowledge have been consistently associated in the literature with better quality of life
and fewer postoperative complications, reinforcing the potential of this technology as a
valuable support tool for nurses conducting preoperative education.
