esults: Intervention practices developed three strategies to initiate and/or implement linkages with community resources: pre-identified resource options, referral guides, and people external to the practice who offered support and connection to resources. To initiate linkages, practices required the capacity to identify patients, make referrals, and know area resources. Linkage implementation could still be defeated if resources were not available, accessible, affordable, and perceived as valuable. Linkages were facilitated by boundaryspanning strategies that compensated for the lack of infrastructure between practices and resources, and by brokering strategies that identified interested community partners and aided mutually beneficial connections with them. Linkages were stronger when they incorporated practice or resource abilities to motivate the patient, such as brief counseling or postreferral outreach. Further, data suggested that sustaining linkages requires continuous attention and ongoing communication between practices and resources.
