“A world that is greatly out of balance in matters of health is neither stable nor secure. . . “ “Primary health care brings balance back to health care, and puts families and communities at the hub of the health system. “ “Primary health care also offers the best way of coping with the ills of life in the 21st century: the globalization of unhealthy lifestyles, rapid unplanned urbanization, and the ageing of populations.” Dr Margaret Chan, Director General, WHO - 2008
Primary Health Care, including health systems strengthening. World Health Assembly adopted a resolution urging member states to “accelerate action towards universal access to primary health care” and “to train and retain adequate numbers of health workers . . . including . . . family physicians. . .” World Health Assembly Resolution WHA62.12 Geneva, World Health Organization, May 2009.

Mortality Outcomes • Primary care physicians: 1 per 10,000 (20%) more primary care physicians decreases mortality by 40 per 100,000 (5% fewer deaths). Family Physicians: 1 per 10,000 (33%) more family physicians results decreases mortality by 70 per 100,000 (9% fewer deaths). • Specialists: 1 per 10,000 (8%) more specialists increases mortality by 16 per 100,000 (2% more deaths).

How good is the evidence? Design: Review of all original clinical research in 3 major general clinical journal or high-impact specialty journals from 1990-2003 that were cited more than 1000 times. Results: Of 49 highly cited studies, 45 claimed that the intervention was effective. • 7 (16%) contradicted by subsequent studies • 7 (16%) found effects stronger than those of subsequent studies • 20 (44%) were replicated • 11 (24%) remained largely unchallenged Source: Ioannidis JPA.
