Primary Care, Health, and Equity
Barbara Starfield, MD, MPH
Supercourse lecture
September 2004
Health systems have several major components:
• Public health activities
• Primary care
• Specialty care
Primary care is the provision of first contact, person-focused ongoing care over time that
meets the health-related needs of people, referring only those
too uncommon to maintain competence, and coordinates
care when people receive services at other levels of care.
Primary health care is primary care applied on a population level. As a population strategy, it requires the
commitment of governments to develop a population-oriented set
of primary care services in the context of other levels and types of
services.
Why Is Primary Care Important?
Better health outcomes
Lower costs
Greater equity in health

In England, each additional primary care physician per 1000
(about a 20% increase) is associated with a decrease in
mortality of about 5%, adjusting for limiting long-term illness and
for various demographic and socioeconomic characteristics.

Health Care Expenditures and Mortality 5 Year Followup:
United States, 1987-92
• Adults (age 25 and older) with a primary care physician rather than a specialist as their personal physician– had 33% lower cost of care– were 19% less likely to die (after
controlling for age, gender, income, insurance, smoking, perceived health (SF-36) and 11 major health conditions)
Many other studies done WITHIN countries, both industrial and developing, show that areas with better primary care have better health outcomes, including
total mortality rates, heart disease, mortality rates, and infant mortality, and
earlier detection of cancers such as colorectal cancer, breast cancer,
uterine/cervical cancer, and melanoma. The opposite is the case for higher
specialist supply, which is associated with worse outcomes.
