Optimising health care within given budgets: Primary prevention of cardiovascular disease in different regions of Sweden

Abstract

This study investigated the consequences of applying strict health maximisation to the choice between three different interventions with a defined budget. We analysed three interventions of preventing cardiovascular diseases, through doctor's advice on smoking secession, through blood-pressure-lowering drugs, and through lipid-lowering drugs. A state transition model has been used to estimate the cost–utility ratios for entire population in three different county councils in Sweden, where the populations were stratified into mutually excluding risk groups. The incremental cost–utility ratios are being presented in a league table and combined with the local resources and the local epidemiological data as a proxy for need for treatment. All interventions with an incremental cost–utility ratio exceeding the threshold ratios are excluded from being funded. The threshold varied between 1687 Euro and 6192 Euro. The general reallocation of resources between the three interventions was a 60% reduction of blood-pressure-lowering drugs with redistribution of resources to advice on smoking secession and to lipid-lowering drugs. One advantage of this method is that the results are very concrete. Recommendations can thereby be more precise which hopefully will create a public debate between decision-makers, practising physicians and patient groups.
