Commentary: Primary Care and Health Outcomes: A Health Services Research Challenge

The contributions of primary care to improvements in many aspects of population and individual health are well documented (Starfield, Shi, and Macinko 2005). In addition to the health benefits, there are reductions in health system costs and reductions in disparities in health across population subgroups. The findings are robust over time and across areas and health systems. International comparisons show that countries with health systems based on strong primary care have better health at lower costs. Studies within countries, including both industrialized as well as middle income and developing countries, are consistent in showing greater improvements in health consequent to legislative and administrative policy initiatives directed at strengthening primary care, including increases in the supply and use of primary care practitioners and clinical improvements in primary care practice. The special and critical features of primary care are well known and include first contact access and use of primary care facilities and practitioners; person-focused (not disease-focused) care over time; comprehensiveness of services available and provided within primary care; and coordination of services when they are needed elsewhere (Starfield, Shi, and Macinko 2005).
