Improving immunisation: coverage in a province in Papua New Guinea.

The effect on immunisation coverage of applying guiding principles to the management of primary health care services in a province in Papua New Guinea is described. These principles were: (a) Each health centre should have a defined geographical area of responsibility. (b) Each health centre should be responsible for a defined population. (c) Each health centre should have defined target groups for immunisation and child health clinic enrollment. (d) An accurate and meaningful reporting system is essential. (e) Each health centre should receive regular feedback on its achievements. Immunisation coverage in the province, as judged by the proportion of children under 1 year of age receiving their second dose of triple antigen, improved from 57-67% in 1980-2 to 89-94% in 1983-4. Immunisation is the most cost effective preventive activity undertaken in child health care. The application of these guiding principles would be relevant in the United Kingdom.
