Lay Summary

This research needs to be done because, despite advancement in current knowledge, the threshold for platelet transfusion in patients with liver disease is not known.

This issue is relevant, as unnecessary transfusions (i.e., transfusions perfomed in patients who are not at risk of bleeding) may expose patients to transfusion-related risks though they do not require this practice. Furthermore, performing selective rather than acritical transfusions in patients who are at higher risk might make platelet transfusions more readily available to patients who are in the need of being transfused.

The aim of this study will be to identify if, among patients who have a similar degree of severity of disase, a subgroup of patients may avoid to be transfused without running the risk of bleeding.

The research will be conducted on data that are already available. The desing of the study will not take into account various arms according to the fact that in some patients a drug was used to increase platelet counts, as we will examine the actual platelet count of the day of the invasive procedure, regardless of how that platelet count was reached.

Application of statistics will identify a platelet count cut-off above which performing invasive manouvres can be regarded as a safe procedure even in patients with decreased platelet count.

The result of this study will not only help plan better studies in the future, but will also
