Rationale: There is a need for medicine to deliver more whole-person care. This is a narrative review of several models of whole-person care and studies that illustrate the business case for whole-person models in primary care. Objectives: To provide an overview of what whole-person care models exist and explore evidence to support these models. Study Selection: Representative whole-person care models widely used in the United States are summarized and evaluated. Selected studies focused on outpatient primary care with examples from programs that integrate the delivery of conventional medical care, complementary and alternative medicine, and self-care within the context of social and cultural environments. Methods: Pubmed search conducted December 2020-February 2021. Two iterative searches using terms for \"Whole Health Veterans Administration,\" \"integrative medicine,\" \"integrative health,\" \"complementary and alternative medicine,\" and, as they related to the outcomes, of \"health outcomes,\" \"cost-effectiveness,\" \"cost reduction,\" \"patient satisfaction,\" and \"physician satisfaction.\" Additional studies were identified from an initial search and the authors\' experience of over 50 years. We looked for studies of whole-person care used in general primary care, those not using a single modality and only from United States practices. Results: A total of 125 (out of 1746) studies were found and met our inclusion criteria. We found that whole-person models of primary care exist, are quite heterogeneous in their approaches, and routinely report substantial benefits for improving the patient experience, clinical outcomes and in reducing costs. Conclusions: Evidence for the benefit of whole-person care models exist but definitions are quite heterogenous and unfocused. There is a need for more standardization of whole-person models and more research using whole systems approaches rather than reductionistic attempts using isolated components.

Integrative health care and complementary medicine are widely used by the U.S. population, yet health professions learners are typically inadequately educated to counsel patients on the use of these approaches. This interprofessional standardized patient exercise (ISPE) provides learners the opportunity to discuss various health care professionals\' roles in caring for a patient interested in integrative health strategies, and to collaborate on a care plan. Utilizing this ISPE format aligns with the principles of integrative health as it requires interprofessional collaboration to address the multifaceted needs of patients.
The ISPE is approximately three hours in duration, and required of all UCSF, third-year dentistry, physical therapy, and medical students; second-year nurse practitioner students, and fourth-year pharmacy students. Social work, nutrition, and chaplain trainees also participated. Working in interprofessional teams of 4-5 learners, team members discuss case information, interview the standardized patient (SP) individually, jointly formulate a care plan, and, discuss the plan with the SP. The experience is debriefed with a facilitator.
In 2016-17, 520 learners participated in the ISPE. They agreed that they learned about the roles of other health care professionals (M = 5.24 on a six-point scale, SD = 1.27), and that they would recommend the ISPE to fellow students in their profession (M = 5.25, SD = 1.30).
Students appreciated the ability to observe learners from other health professions interacting with the SP, and how different perspectives and expertise were integrated to create a comprehensive care plan. The exercise can be adapted to accommodate local health professions learners.
