Study description

CESIT is an Italian multicenter retrospective cohort study on the use of immunosuppressive drugs in transplant patients, based on information available in regional administrative healthcare databases and on National Transplant Information System (SIT). The aims are: 1) to describe the prescriptive patterns of immunosuppressive drug regimens in different transplant settings (kidney, lung, liver, heart) used in maintenance phase and to identify patient characteristics associated to these patterns in the four Italian regions (Lombardy, Veneto, Lazio, Sardinia), accounting for over 20 million residents, 2) to compare the risk-benefit profile of different immunosuppressive therapeutic regimens, with a focus on generics/branded and special populations (paediatric and elderly) 3) to evaluate data validity and generalizability through SIT All transplant patients residing in the regions involved in the study will be identified through an algorithm considering all the hospitalizations, occurred over the years 2009–2019, reporting a transplantation procedure . Comorbidity will be defined from Hospital discharge records (ICD-9-CM codes), disease specific copayment exemptions, and, as far as possible, disease specific drug treatments and NTIS. Drug utilisation patterns will be based on drugs (ATC codes) prescribed to outpatients using the DDDs. Specific outcomes, such as organ survival and rejection, will be identify by SIT. Safety and effectiveness will be investigated using a new-user approach and applying both, intention-to-treat and as-treated analysis. Data and analysis will be managed through a common data model, with shared data scripts, performing the analysis and pooling aggregated anonymous data to obtain overall results.
