Evaluation of interactions in conventional and complementary medicine care pathways in Switzerland
Dr David De Ridder, Dr Christophe Bagnoud, Dr Stéphane Joost, Prof Idris Guessous
This research project focuses on the relationship between complementary and conventional medicine (CM) in Switzerland. Complementary and alternative medicine (CAM) is widely used by Swiss citizens, but the integration of CAM into patient care pathways and its cost-effectiveness are poorly understood. The project aims to analyze patterns of CAM utilization, financial implications of CAM usage in patient care, and the …
Commune en santé
