Effect of mental health collaborative care models on primary care provider outcomes: an integrative review

Background: Collaborative care models (CCMs) have robust research evidence in improving mental health outcomes for diverse patient populations with complex health care needs. However, the impact of CCMs on primary care provider (PCP) outcomes are not well described. Objective: This integrative review synthesizes the evidence regarding the effect of mental health CCMs on PCP outcomes. Methods: PubMed, CINAHL, Web of Science, and PsycInfo were systematically searched using key terms, with inclusion criteria of English language, peer-reviewed literature, primary care setting, PCP outcomes, and mental health CCM. This resulted in 1,481 total records, with an additional 14 records identified by review of reference lists. After removal of duplicates, 1,319 articles were reviewed based on title and abstract, 190 full-text articles were assessed, and a final selection of 15 articles were critically appraised and synthesized. Results: The articles included a wide variety of sample sizes, designs, settings, and patient populations, with most studies demonstrating low or moderate quality evidence. Although CCMs had an overwhelmingly positive overall effect on PCP outcomes such as knowledge, satisfaction, and self-efficacy, multiple logistical barriers were also identified that hindered CCM implementation such as time and workflow conflicts. Adaptability of the CCM as well as PCP enthusiasm enhanced positive outcomes. Newer-to-practice PCPs were more likely to participate in CCM initiatives. Conclusion: Accumulating evidence supports CCM expansion, to improve both patient and PCP outcomes. Logistical efforts may enhance CCM adaptability and workflow. Further studies are needed to specifically examine the effect of CCMs on PCP burnout and retention.
