Factors affecting primary care implementation for older veterans with multimorbidity in Veterans Health Administration (VA).

Older veterans with MCC have complex primary care needs requiring high levels of care management and coordination. Knowing what key factors affect GeriPACT implementation is critical. Study findings also contribute to the growing implementation science literature on applying CFIR to evaluate factors that affect program implementation, especially to aging research. Further studies on MCC-focused specialty primary care will help facilitate patient-centered care provision for older adults' complex health needs while also leveraging synergistic work across factors affecting implementation.
