Compassionate drug uses in Italy. Analysis at single-center level.

Using a database from two pharmaceutical companies that managed several compassionate use programs in the last few years in Italy, we have previously analyzed the data by the number of patients and centers in each region and province, showing that the use of compassionate drugs is largely diffused in the country, in a manner directly related to the size of population of each region. In the present study we used the same database to expand the analysis to single-center level, aiming to test the hypothesis whether, despite a good diffusion of compassionate drug uses in each region, the majority of them concentrates within a relatively low number of centers.
