Title: Developing and determining the effect of a mobile application for patients undergoing cardiac surgery and cardiovascular surgery intensive care unit nurses

Abstract

Patients undergoing cardiac surgery often experience a lack of knowledge regarding preoperative preparation and postoperative intensive care, which negatively affects their anxiety, depression, and comfort levels. At the same time, nurses working in cardiovascular surgery intensive care units face challenges related to increasing technological complexity and require standardized educational materials. This project aims to develop a mobile application to support patients’ preparation processes and provide guidance for nurses in delivering quality care. In the first stage, the application content will be developed with expert opinions, tested for clarity with patients and nurses, and finalized. Necessary videos will be prepared, and the software development will be completed. In the second stage, a randomized controlled trial will be conducted to examine the effect of the mobile application on patients’ anxiety, depression, comfort, and intensive care experiences. Data collection will involve the Hospital Anxiety and Depression Scale, the Early Postoperative Comfort Scale, and the Intensive Care Experience Scale. Triple blinding will be applied to minimize bias. For nurses, the Self-Efficacy Scale will be administered before and after the use of the mobile application to measure changes in perceived self-efficacy. This project represents the first initiative in Turkey to develop a mobile application specifically for both cardiac surgery patients and intensive care nurses. It is expected that the application will enhance patients’ psychosocial adaptation, improve nurses’ self-efficacy, and contribute to the standardization of care. Furthermore, this practical, evidence-based approach is anticipated to increase patient satisfaction, strengthen nurse-patient communication, and facilitate the integration of evidence-based practices into clinical settings. The first phase of the project has been completed, and a mobile application has been developed for both patients and nurses. In the next phase, the effectiveness of the mobile application will be evaluated. The first phase of the project has been completed, and this stage will be presented at the congress.

Key Takeaways:

- Participants will learn how mobile applications can address knowledge gaps in cardiac surgery patients.

- They will understand how technological tools can enhance nurses’ self-efficacy in intensive care settings.

- They will explore the role of mobile health applications in improving standardization and quality of patient care.

- They will recognize the contribution of randomized controlled trials in providing high-level evidence for mobile health interventions.
