Hospitals are increasingly recognizing the importance of moving away from the traditional medical model of care to more collaborative models that integrate patients and families into the planning and delivery of healthcare. A few existing studies suggest that collaborative models of care result in higher levels of consumer satisfaction, treatment compliance, effective team performance, and increased care coordination (Gance-Cleveland, 2005; DiMatteo et al., 2002; Reid Ponte et al., 2004; Institute for Family-Centered Care, 2004). Key values underpinning social work practice make medical social workers well-positioned to play leadership roles as hospitals make the shift to more patient-centered care. Specific strategies are presented for medical social workers to use in advocating for change in the way health services are planned and delivered within hospital settings.
