The number of patients in the United States with multiple chronic conditions (MCC) is growing. Many patients with poorly controlled MCC also have unhealthy behaviors, mental health challenges, and unmet social needs. Medical management of MCC may have limited benefit if patients are struggling to address these basic life needs. Health systems and communities increasingly recognize the need to address these issues and are experimenting with and investing in new models for connecting patients with needed services. Yet primary care clinicians, whose regular contact with patients makes them more familiar with patients' needs, are often not included in these systems. Responding to the Special Emphasis Notice NOT-HS-16-013, Optimizing Care for People Living with MCC through the Development of Enhanced Care Planning, the investigators propose a clinician-level randomized controlled trial to study how primary care clinicians can participate in these community and hospital solutions and whether doing so is effective in controlling MCC. This study will build on the Centers for Medicare and Medicaid Services (CMS)-funded Accountable Health Community (AHC) in Richmond, Virginia. Sixty clinicians in the Virginia Ambulatory Care Outcomes Research Network (ACORN) will be matched by age and sex and randomized to usual care (control condition) or enhanced care planning with clinical-community linkage support (intervention). From the electronic health record (EHR), clinicians will identify all patients with MCC, including cardiovascular disease or risks, diabetes, obesity, or depression. A baseline assessment will be mailed to 50 randomly selected patients; 10 respondents per clinician (600 patients total) with uncontrolled MCC will be randomly selected, with over-sampling of minorities. The intervention includes two components. First, an enhanced care planning tool called My Own Health Report (MOHR) will screen patients for health behavior, mental health, and social needs. Clinical navigator support will help patients prioritize needs, create care plans based on preferences, and write a personal narrative to guide the care team. Patients will update care plans quarterly. Second, community-clinical linkage support will include community resource registries, personnel to span settings (clinical navigators, community health workers), and care team coordination tools (sharing MOHR content, secure messaging, and virtual visits). The investigators will compare patient-level intervention and control outcomes to assess improvements in MCC outcomes (primary outcome) and self-reported PROMIS-29 measures (physical health, mental health, social wellbeing) six months and two years post-enrollment. the investigators will also conduct a mixed-methods, multilevel assessment of person-, family-, community-, and system-level contextual influences on implementation and effectiveness. Data sources will include EHR and MOHR data, chart reviews, patient surveys, field notes, and semi-structured interviews of patients, clinicians, and community stakeholders. If effective, this study will help inform efforts by primary care clinicians to participate in the growing number of AHC-like systems as a strategy to better control MCC.
