Abstract [en]

This thesis addresses the health economic evaluation of community-based interventions against cardiovascular disease (CVD), with special emphasis on the Västerbotten Intervention Project (VIP), run since 1985.

The framework is a simple evaluation model consisting of two parts; the selection and measurement of empirical consequences caused by the project under evaluation (e.g. changes in mortality, well-being, use of resources) and a set of values (e.g. efficiency, equity) aimed at assessing the goodness of these consequences.

The project’s effects on CVD were predicted by means of risk factors measured in Norsjö between 1985-1990, applied to an epidemiological model based on a logistic risk equation derived from the Framingham population. Cost per life-years saved ranged from £14 900 to net savings, depending on the assumptions. The favourable cost-effectiveness in this kind of intervention has earlier been predicted from theoretical models, but this is the first study based on real experiences from contemporary community-based interventions against CVD. Furthermore, all social classes have benefited from the intervention. Also potential adverse effects in the form of excess mortality due to low cholesterol levels were investigated, and they were negligible in comparison with the health gains.

The value of an intervention from a citizen’s perspective was investigated through an interview study (n≈100) in accordance with the contingent valuation method. Great expectations concerning mortality effects on the community level and future savings in health care were good predictors for assigning the intervention a high value. On the contrary, personal benefits in the form of a decreasing risk for CVD had no positive association with the value of the intervention. Hence, the consequences that the cost-effectiveness analysis accounts for - mortality and savings - coincide with the most valuable consequences from the citizen's perspective.

In a democracy, the set of values used to determine the success or failure of a programme like a prevention project must agree with values held by the majority of the citizens. Therefore, the attitudes to ethical values among Swedish politicians (n≈450) responsible for health care have been mapped. The support for the health maximization principle was weak, and a trade-off between efficiency and equity was preferred. About 70% of the respondents were prepared to sacrifice health gains to achieve increased equity.
