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. Starfield 09/04 04-133 Starfield 09/04 H 2944
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.

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.

What We Already Know A primary care oriented system is important for • Improving health (improving effectiveness) • Keeping costs manageable (improving efficiency) Starfield 09/05 PC 3316
Does primary care reduce inequity in health? Starfield 09/04 04-142 Starfield 09/04 EQ 2966
Equity in health is the absence of systematic and potentially remediable differences in one or more aspects of health across population groups defined geographically, demographically, or socially. Starfield 04/04 04-050 Starfield 04/04 EQ 2820 Source: www.iseqh.org
In the United States, an increase of 1 primary care doctor is associated with 1.44 fewer deaths per 10,000 population.The association of primary care with decreased mortality is greater in the African-American population than in the white population.

In 7 African countries • The highest 1/5 of the population receives well over twice as much financial benefit from overall government health spending (30% vs 12%). • For primary care, the poor/rich benefit ratio is much lower (23% vs 15%). “From an equity perspective, the move toward primary care represents a clear step in the right direction.” Source: Gwatkin, Int J Epidemiol 2001; 30:720-3, based on Castro-Leal et al, Bull World Health Organ 2000; 78:66-74.

Studies in other developing and middle income countries also show benefit from primary care reform. • In Bolivia, reform in deprived areas lowered under-5 mortality rates compared with comparison areas. • In Costa Rica, primary care reforms in the 1990s decreased infant mortality and increased life expectancy to rates comparable to those in industrialized countries. • In Mexico, improvements in primary care practices reduced child mortality in socially deprived areas.

Primary Care and Health: Evidence-Based Summary • Countries with strong primary care • have lower overall costs • generally have healthier populations • Within countries • areas with higher primary care physician availability (but NOT specialist availability) have healthier populations • more primary care physician availability reduces the adverse effects of social inequality Starfield 09/02 PC 2214 Starfield 09/02 02-161
Conclusion Virchow said that medicine is a social science and politics is medicine on a grand scale. Along with improved social and environmental conditions as a result of public health and social policies, primary care is an important aspect of policy to achieve effectiveness, efficacy, and equity in health services. Starfield 03/05 PC 3112
Conclusion Although sociodemographic factors undoubtedly influence health, a primary care oriented health system is a highly relevant policy strategy because its effect is clear and relatively rapid, particularly concerning prevention of the progression of illness and effects of injury, especially at younger ages.
