Falls are a major public health problem for older adults, and community-based organizations play a key role in educating seniors about falls prevention (FP). We conducted a qualitative process evaluation at six sites to report community-based centers' perspectives on adoption, adaptation, and sustainability of an evidence-based multifactorial FP model. Wide dissemination of new health-oriented programs requires marketing to center directors, who must consider sustainability options. The diversity and independence of community-based organizations, together with current staffing and funding limitations, suggest that fidelity to multifactorial evidence-based interventions will be difficult to achieve.
