Governments often use PPP without placing projects within an overall health policy. This can lead to problems in policy implementation. If, for example, the goals of health policy are to improve access for patients to primary health care and a country initiates an expensive PPP hospitals programme, then much of the funding from the national health budget will be considerably used up and not enough will be left to pay for the necessary investments in the primary health care sector. Accordingly PPP should be placed within the overall targets and objectives of its health policy if coherence and delivery are to be assured.
