To identify factors affecting implementation of Geriatric Patient‐Aligned Care Teams (GeriPACTs), a patient‐centered medical home model for older adults with complex care needs including multiple chronic conditions (MCC), designed to provide them with comprehensive, managed, and coordinated primary care.

Data Sources

Qualitative data were collected from key informants at eight Veterans Health Administration Medical Centers geographically spread across the United States.

Study Design

Guided by the Consolidated Framework for Implementation Research (CFIR), we collected prospective primary data through semi‐structured interviews with GeriPACT team members (e.g., physicians, nurses, social workers, pharmacists), leaders (e.g., executive leaders, middle managers), and other staff referring to the program.

Data Collection

We conducted in‐person, semi‐structured interviews with 134 key informants. Interviews were recorded with permission and professionally transcribed. Transcripts were coded in 11. We used directed content analysis to identify key factors affecting GeriPACT implementation across sites.

Principal Findings

Five key factors affected GeriPACT implementation—five CFIR constructs within two CFIR domains. Within the domain two constructs emerged, namely, (1) the structure of the GeriPACT model and (2) design, quality, and packaging. Within the domain, we identified three constructs, namely, (1) available resources (e.g., staffing and space, and infrastructure and information technology), (2) leadership support and engagement, and (3) networks and communications including teamwork, communication, and coordination.


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.
