Abstract
OBJECTIVE: Drawing from the articles presented in this special issue, to provide an overview of three key challenges facing researchers in the area of organizational issues in primary care delivery to older adults. CONCLUSIONS: To improve the quality of research done in this area we would recommend that researchers attend to the complexity of (1) defining an appropriate unit of analysis; (2) reframing our traditional models of service delivery to reflect ongoing changes in healthcare system actors and boundaries; and (3) reconceptualizing the outcomes of care to reflect adequately the reality of care for the aging patient.
