Improving home-based providers' communication to primary care providers to enhance care coordination

Objectives: Health care system fragmentation is a pervasive problem. Research has not delineated concrete behavioral strategies to guide providers to communicate with personnel in other organizations to coordinate care. We addressed this gap within a particular context: home-based providers delivering depression care management (DCM) to older adults requiring coordination with primary care personnel. Our objective was to pilot test a communication protocol ('BRIDGE - BRinging Inter-Disciplinary Guidelines to Elders') in conjunction with DCM. Method: In an open pilot trial (N = 7), home-based providers delivered DCM to participants. Following the BRIDGE protocol, home-based providers made scripted telephone calls and sent structured progress reports to personnel in participants' primary care practices with concise information and requests for assistance. Home-based providers documented visits with participants, contacts to and responses from primary care personnel. A research interviewer assessed participant outcomes [Symptom Checklist-20 (depressive symptoms), World Health Organization Disability Assessment Schedule-12, satisfaction] at baseline, three months, and six months. Results: Over 12 months, home-based providers made 2.4 telephone calls and sent 6.3 faxes to other personnel, on average per participant. Primary care personnel responded to 18 of 22 requests (81.8%; 2 requests dropped, 2 ongoing), with at least one response per participant. Participants' depressive symptoms and disability improved significantly at both post-tests with large effect sizes (d ranged 0.73-2.3). Participants were satisfied. Conclusion: Using BRIDGE, home-based providers expended a small amount of effort to communicate with primary care personnel, who responded to almost all requests. Larger scale research is needed to confirm findings and potentially extend BRIDGE to other client problems, professions, and service sectors.
