Part II. Primary care for the medically underserved: Challenges and opportunities

The medically underserved present unique challenges to primary care practitioners. Sociocultural and financial barriers of the underserved impede access to necessary care; the prevalence and severity of diseases in the underserved population vary from those of the general population; the institution of preventive-care measures can be especially problematic; and the doctor-patient relationship is uncommonly complex. This article reviews current thinking about the causes of unequal health, the effects of unequal health care, and the special opportunities for disease prevention among the socioeconomically disadvantaged people in the US. Sensitivity to these and other issues can enhance primary care practitioners' efforts to improve care of the underserved now, pending future political consensus about universal health insurance.
