The Community Primary Care Champions Fellowship: a mixed methods evaluation of an interprofessional fellowship for physician assistants and physicians.

BACKGROUND: Primary care in the US faces challenges with clinician recruitment, retention, and burnout, with further workforce shortages predicted in the next decade. Team-based care can be protective against clinician burnout, and opportunities for interprofessional education (IPE) on professional development and leadership could encourage primary care transformation. Despite an increasingly important role in the primary care workforce, IPE initiatives training physician assistants (PAs) alongside physicians are rare. We describe the design, curriculum, and outcomes from an interprofessional primary care transformation fellowship for community-based primary care physicians and PAs. METHODS: The Community Primary Care Champions (CPCC) Fellowship was a one-year, part-time fellowship which trained nine PAs, fourteen physicians, and a behavioralist with at least two years of post-graduate clinical experience in six content pillars: quality improvement (QI), wellness and burnout, mental health, social determinants of health, medical education, and substance use disorders. The fellowship included a recurring schedule of monthly activities in self-study, lectures, mentoring, and community expert evening discussions. Evaluation of the fellowship included pre, post, and one-year follow-up self-assessments of knowledge, attitudes, and confidence in the six content areas, pre- and post- wellness surveys, lecture and discussion evaluations, and midpoint and exit focus groups. RESULTS: Fellows showed significant improvement in 24 of 28 self-assessment items across all content areas post-fellowship, and in 16 of 18 items one-year post-fellowship. They demonstrated reductions in emotional exhaustion and depersonalization post-fellowship and increased confidence in working in interprofessional teams post-fellowship which persisted on one-year follow-up assessments. All fellows completed QI projects and four presented their work at national conferences. Focus group data showed that fellows experienced collaborative, meaningful professional development that was relevant to their clinical work. They appreciated the flexible format and inclusion of interprofessional community experts in evening discussions. CONCLUSIONS: The CPCC fellowship fostered an interprofessional community of practice that provided an effective IPE experience for physicians and PAs. The learning activities, and particularly the community expert discussions, allowed for a flexible, relevant experience, resulting in personal and professional growth along with increased confidence working within interprofessional teams.

Elevated Aggression and Reduced White Matter Integrity in Mild Traumatic Brain Injury: A DTI Study.

Mild traumatic brain injury (mTBI) remains the most commonly reported head injury in the United States, and is associated with a wide range of post-concussive symptoms including physical, cognitive and affective impairments. Elevated aggression has been documented in mTBI; however, the neural mechanisms associated with aggression at the chronic stage of recovery remain poorly understood. In the present study, we investigated the association between white matter integrity and aggression in mTBI using diffusion tensor imaging (DTI). Twenty-six age-matched adults participated in the study, including 16 healthy controls (HCs) and 10 individuals in the chronic stage of recovery (either 6-months or 12 months post-mTBI). Psychological measures of aggression included the Buss-Perry Aggression Questionnaire and the Personality Assessment Inventory (PAI). Axonal pathways implicated in affective processing were studied, including the corpus callosum, anterior thalamic radiation, cingulum and uncinate fasciculus, and measures of white matter integrity included fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD) and axial diffusivity (AD). We found that adults with mTBI in the chronic stage of recovery had higher levels aggression. Individuals with mTBI also had greater RD in the corpus callosum compared to HCs, indicating reduced fiber integrity. Furthermore, we observed a significant association between reduced white matter integrity in the corpus callosum and greater aggression. Our findings provide additional evidence for underlying neuroanatomical mechanisms of aggression, although future research will be necessary to characterize the specific relationship between aggression and the white matter pathways we identified.
