The cross-specialty application of appropriate traditional Chinese medicine (TCM) techniques has become an important trend in the development of integrated nursing. However, due to professional barriers and systemic differences, the standardized promotion of these techniques faces significant challenges, which affect the homogenization of nursing service quality and the continuous optimization of patient outcomes. This paper reviews the application scenarios, application models, and barriers to the cross-specialty use of TCM appropriate techniques, aiming to provide a theoretical basis and practical reference for promoting the high-quality development of integrated Chinese and Western medicine nursing.
