The impact of public health interventions in a developing nation: an overview

Introduction: Around 80% of factors that determine population health sit outside the control of health services. It is essential we influence these factors in addition to those within the remit of health services in order to improve and protect the health of population in a developing country. Public health functions encompass working across the domains that constitute population health systems with various partners. The objective of this article is to give an overview of public health interventions that can improve the health of the population of a developing nation. Method: A descriptive study, based on a review of the literature of key public health frameworks and interventions that are likely to have significant impacts on population health. Some selected public health interventions and case studies are highlighted to illustrate the importance of priority areas in developing countries. Results: Various public health frameworks recognise the importance of wider determinants of health (socio-economic factors), effective healthcare, healthy behaviours, working with communities as critical to securing population health. Another framework adopts a life-course model of intervention starting from public health interventions during preconception period and childhood, adolescence, working life and older age. For many developing countries, the author identified some examples of priority areas for interventions such as stopping and preventing wars; improving child health, including free school meals; achieving universal healthcare through integrated primary health care; addressing commercial determinants of health; embracing new technologies; and measuring and monitoring population health. Conclusion: In order to improve the health of a population in a developing country, attention needs to go beyond health services to influence the wider determinants of health, health behaviours and adopting the World Health Organisation's roadmap on essential public health functions.

Integrated Primary Health Care (iPHC) for developing countries: a practical approach in South Sudan

Introduction: The founding vision of Primary Health Care (PHC) adopted in Alma Atta in 1978 has not worked as a result a number of countries have sought to re-engineer their own healthcare systems. Healthcare model in most developing countries needs to change from that inherited from the colonial era, which is predominantly hospital-based. Objective: To describe an integrated primary health care (iPHC) model which encompasses public health services with enhanced basic diagnostic and curative services as a cost-effective delivery of healthcare in the rural areas where 95% of the population resides.Method: A descriptive study of a proposed iPHC model following situational analyses and literature review of primary healthcare experiences from around the world with a view to inform a practical approach in South Sudan.Results: The iPHC model consists of five pillars: (1) public health services (2) clinical services (3) universal registration of population in the catchment areas; (4) a standard building infrastructure; and (5) training of multi-disciplinary healthcare workforce. Once operational, within five years it is envisaged that one fully functioning iPHC centre can provide universal access to healthcare service to 10,000 population resident in a geographical catchment area.Conclusion: South Sudan has a unique opportunity to improve the health of its population by embracing a new model of delivering health care: the iPHC. This model is simple, and can be the basis of delivering a health service for the rural population
