We use the ARIMA model with intervention in order to analyse the epidemiological situation of whooping-cough in England and Wales for the period of 1940-1990. The ARIMA modelling of this illness contains intervention variables, such as the introduction of widespread vaccination in 1957 and the fall in the level of vaccination down to 30% in 1978. The results of this analysis confirm the role of the intervention variables on the evolution of the morbidity due to whooping-cough, by quantifying their impact on the level of the morbidity, as well as the delay needed before they have an influence on the increase of recorded cases of whooping-cough.

The 1993 Health and Disability Services Act heralded a range of structural reforms in the New Zealand health care system. Despite these reforms considerable resources being spent on convincing consumers of their merits, have failed to gain widespread public approval. This paper examines two key issues that have arisen during the reform process. ⋯ Unacknowledged conflicts of interest have helped to undermine the priority setting process. The discussion suggests that it may be increasingly difficult for any government in future to determine the allocation of resources without taking private sector interests and rising public concern into account. It remains to be seen which of these factors is more powerful.
