Stop, Listen, and Learn: Using Mixed Methods to Add Value to Clinical Trials.

This commentary discusses the concept of value-based or value-focused health care as a rationale for researchers to incorporate mixed methods study designs a priori into clinical trials evaluating traditional, complementary, alternative, and integrative medicine (TCAIM). Along with assessing patient outcomes, information about patients' experiences and preferences are needed to determine the value of an intervention. Incorporating a mixed-methods approach can improve the quality of clinical trials and provide important information about the potential value of the intervention.
