Brief description of the studyIncretin based drugs represent a class of hypoglicemic agents including different molecules approved during the last decade for the treatment of type 2 diabetes (T2DM). The clinical efficacy of this class of drugs in the treatment of T2DM relies on the potentiaton of the activity of the glucagon-like peptide 1 (GLP-1), an endogenous hormon belonging to the family of incretins that exerts an important role in the glycemic omeostasis. In particular, on the basis of the mechanism of action, incretin-based drugs can be distinguished in two groups: glucagon like peptide-1 analogues and dipeptidilpeptidase-4 inhibitors (DPP4i). Different randomized clinical trials demonstrated a positive risk/benefit profile for these hypoglicemic agents. However, given the relatively recent commercialization, evidence on the pattern of use of these medications in clinical practice is still scarce. Different incretin based medicines are currently available in Italy. Although a trend of increase of their use has been reported in literature, specific information concerning GLP-1 analogues and DPP-4i or the individual molecules belonging to the two groups are still lacking. Moreover, since the effectiveness and safety profile of these drugs cannot be considered completely established yet, evidence on the exposure of the general population to these medications, as well as the characterization of treated patients, becomes of paramount importance for planning large scale observational pharmacoepidemiological studies.
Therefore, the aim of this study is to describe in greater details the pattern of use of incretin-based drugs in a large sample of the Italian general population. For this purpose, electronic health records from three population-based administrative data bases collecting information on almost 6 million inhabitants from 2 Italian regions, Tuscany and Umbria, and one Local Health Authority, Caserta, will be analyzed.

15. Data analysis plan
Please provide a brief summary of the analysis method
The annual incidence and prevalence of use of incretin-based therapies, in the general population will be calculated per each year of the period 2008-2014. The annual percentages of incident and prevalent incretin users on total number of users of antidiabetics will be observed. Annual percentage of new users of GLP-1 analogues, DPP-4 inhibitors and relevant actcive principles belonging to the two groups will be calculated on the total number of new users of incretin-based therapies. Incident incretin users will be described in terms of demographic characteristics, previous antidiabetics treatments and other drug therapies.
