Objective: To assess whether primary care performance of low-income women's primary care delivery sites is associated with the strength of their relationships with their physicians. Design: Random-digit-dial and targeted household telephone survey of a population-based sample. Setting: Washington, D.C. census tracts with greater than or equal to30% of households below 200% of federal poverty threshold. Participants: Women over age 40 (N=1,205), 82% of whom were African American. Measurements and main results: The response rate was 85%. Primary care performance was assessed using women's ratings of their systems' accessibility (organizational, geographic, and financial), continuity, comprehensiveness, and coordination. Respondents' ratings of trust in their physicians, communication with their physicians, and compassion shown by their physicians were used to operationalize the patient-physician relationship. Controlling for population and insurance characteristics, 4 primary care features were positively associated with women's trust in and communication with their physicians: continuity with a single clinician, organizational accessibility of the practice, comprehensive care, and coordination of specialty care services. Better organizational access, but not geographic or financial access, was associated with greater levels of trust, compassion, and communication (adds ratios [ORs], 3.2, 7.4, and 6.9, respectively; Pless than or equal to.01). Women who rated highest their doctor's ability to take care of all of their health care needs (highest level of comprehensiveness) had 11 times the odds of trusting their physician (P less than or equal to.01) and 6 times the odds of finding their physicians compassionate and communicative (Pless than or equal to.01), compared to those with the lowest level of comprehensiveness. Conclusions: Primary care delivery sites organized to be more accessible, to link patients with the same clinician for their visits, to provide for all of a woman's health care needs, and to coordinate specialty care services are associated with stronger relationships between low-income women and their physicians. Primary care systems that fail to emphasize these features of primary care may jeopardize the clinician-patient relationship and indirectly the quality of care and health outcomes.
