The Geriatric Interprofessional Team Transformation for Primary Care (GITT-PC) is a model developed to deliver optimal care to older adults in primary care. GITT-PC is an expansion of the John A. Hartford Foundation Geriatric Interdisciplinary Team Training (GITT) program developed at New York University and funded from 1995 to 2002 (Fulmer et al., 2004). GITT was designed to create training models that reflect the needs of the changing health care system and the challenge of caring for older adults with complex conditions (Fulmer et al., 2005). The GITT-PC model builds on the lessons learned from GITT and the development of curricula and training materials based on best practices. Implementation of GITT-PC is accomplished through systems and practices that meet the needs and preferences of patients and their families and that are implemented by teams of health professionals and community service providers. GITT-PC is focused on four core components of high-quality geriatric care: (1) health promotion and prevention, (2) chronic disease management, (3) advanced care planning, and (4) transitional care management, each component corresponding to a Medicare-reimbursable visit. Implementation of these reimbursable services enables practices to provide evidence-based geriatric care while realizing a potential significant return on investment. The GITT-PC model has evolved from an academic training program to a financially sustainable model that serves to improve the care of older adults through a systematic team transformation process that makes a clear business case for primary care (Tabbush et al., 2021). The GITT-PC training program can be implemented in primary care practices with a focus on improving or expanding delivery of annual wellness visits (AWVs) and, potentially, registered RN-led AWVs.
