  1. The relationship between the supply of cardiac catherization laboratories, cardiologists and the use of invasive cardiac procedures in Northern New England.

    Article - En anglais

    Objectives 

    Utilization rates of coronary angiography and cardiac revascularization have been found to vary between areas.

    This study addresses the relationship between resource supply and procedure rates.

    Methods 

    We compared the association of per capita catherization laboratories, per capita cardiologists and multi-provider markets (where more than one hospital offers coronary angiography services) with the utilization rates for angiography and cardiac revascularization in northern New England, USA.

    Administrative data were used to capture invasive cardiac procedures.

    Small area analyses were used to create coronary angiography service areas.

    Linear regression methods were used to measure associations between the resource supply and utilization rates.

    Results 

    Variation in the use of invasive cardiac procedures was strongly associated with the population-based availability of catheterization facilities and multi-provider markets and unrelated to cardiologist supply or need (as reflected in the hospitalization rates for myocardial infarction).

    In the multivariate model, an increase of 1 catheterization laboratory per 100 000 population was associated with an increase in the angiography rate of 1,62 per 1 000 population ; those service areas with multi-provider markets were associated with an additional increase in the angiography rate of 1,27 per 1 000 population (R²=0,84, p=0,0006).
