Application of the conceptual model of Jean Watson's Theory of Humanistic Caring in patients after TA-TAVI

Introduction: Jean Watson's theory of humanistic care is a humanistic-existential framework for nursing based on relationality, empathy, and spiritual presence. In the highly technical environment of cardiac surgery, such as TA-TAVI, it enables a human and holistic approach to the patient. Goal: To systematically evaluate the available evidence on the application of the Watson model in nursing care for patients after transapical transcatheter aortic valve implantation (TA-TAVI). Methods: A systematic review study in accordance with the PRISMA 2020 recommendations and the PICO(S) methodological framework. Searches in PubMed, Scopus, CINAHL, Web of Science, and Google Scholar databases (2000-2025). After removing duplicates and irrelevant records, 20 studies were included in the qualitative synthesis. Results: The identified studies demonstrate the benefits of the Watson model for improving nurse-patient communication and relationships, promoting psychospiritual well-being, reducing stress and anxiety, strengthening professional identity, and treatment adherence. Barriers to implementation include limited time, personnel capacity, and institutional support. Conclusion: The Watson model has significant potential to improve nursing care after TA-TAVI. Its implementation requires structural support, education, and cultural change towards value-based practice.
