Physicians and pharmacists have differing but complementary roles that can optimize patient care when structured effectively. Unfortunately, these two professionals are not collaborating well enough, as patient outcomes, especially in relation to medication adherence, continue to decline. Coordinated care of patients can improve by expanding bidirectional communication and sharing additional patient information with each other. It will be necessary to continue to promote collaborative care in the educational and training stages of these professionals’ careers to build trust and understanding of professional scope. Ultimately, the healthcare infrastructure will have to continue to progress to make collaboration more available and valuable to physicians and pharmacists.
