Primary health care is an approach to health and a spectrum of services beyond the traditional health care system while primary care is just one element within PHC that focuses on health care services. The present status of PHC in Malaysia and the strides it has made in uplifting the health status of the nation is described. The challenges that the Malaysia health system are facing have necessitated a review of the structure of the whole health system and reforms in PHC will ensue in due course. The concept of 1Care, the proposed re-structuring of the health system, is discussed with emphasis on the reform in the PHC delivery system. The reforms are aimed at addressing three main concerns on seamless integration of care especially for the management of chronic diseases, ensuring universal coverage and responsiveness of the health system in the face of increasing client expectations and patient safety. The opportunity for macro reform to improve the health of Malaysians by developing a sustainable and high performing health care system is being seized by the Ministry of Health in 1Care. The micro reforms are discussed as regards to increasing access to services, development of primary health care teams to deliver comprehensive PHC, the application of ICT, the renewed emphasis on health promotion & prevention activities and a renewed focus on community empowerment and participation. Support in terms of human resource, governance & funding models, capacity building in monitoring & evaluation as well as change management to affect the reforms are identified. The paper concludes with lessons learnt from other countries and the importance of systemic reform for a well functioning health delivery system.
