ABSTRACT: ADMINISTRATIVE CORE The Administrative Core (AC) will catalyze and champion LeaHD’s mission, goals and activities. Specifically, the AC will: 1) provide administrative and financial management, and coordinate interactions among leadership, co-investigators, scientists, and mentors from affiliated universities, health systems, and community partners; 2) develop and execute a recruitment and retention plan, solicit proposals, review applications, and submit required regulatory documents for research projects; and 3) employ clear outcome and impact metrics to evaluate and document LeaHD activities. The AC will establish and lead activities of the LHS Innovation Hub of nine engaged health system partners, and serve as a point of contact for LeaHD activities. The AC will facilitate communications with both internal and external parties. It will develop and maintain a contact database, website, and a strong social media presence. The AC’s comprehensive plan to recruit and retain a diverse pool of applicants for scientist positions will be enhanced through the input of a Recruitment and Outreach Advisory Committee and will be strengthened by a Community Outreach Network of external partners who are committed to diversity, equity, and inclusion efforts relative to the workforce serving persons with disability and chronic conditions. The AC will develop calls for LeaHD scientists, coordinate review and selection, and collaborate with the Research Education Core (REC) to develop a strategy for ensuring viability of mentoring and training relationships. The AC will communicate with mentors, and finalize plans for supporting mentoring activities. The AC and REC will work together to oversee completion of individualized development plans and mentoring agreements. The AC will work with the Research and Data Analysis Core (RDAC) to plan for PCOR/CER project solicitation, review, selection, and resource requirements. Finally, the AC will implement a comprehensive program evaluation that employs clear impact metrics. The AC’s success will be facilitated by its strong and experienced leadership, and established, effective collaborations between PIs, co-investigators, and partner health systems institutions. Linda Resnik, PT, PhD will serve as AC Principal Investigator. Dr. Resnik is the Director of two research and training centers, the NIH-funded Learning Health Systems (LHS) Rehabilitation Research Resource Center (LeaRRn), and the Center on Health Services Training and Research (CoHSTAR), funded by the Foundation for Physical Therapy Research. AC Co- investigator Janet Freburger is the Director of LeaRRn’s Health System Innovation Hub and co-Principal Investigator of LeaRRn’s LHS mentored Scholars. Together, Resnik and Freburger have developed relationships and worked closely with 10 health system partners to identify research priorities, and match dozens of LeaRRn’s LHS Scholars to health systems to develop research projects to address health system needs. The AC will be guided by an Executive Committee that includes Resnik, Freburger, and REC PI Theresa Shireman.
