Aim: The aim of this study is to examine the role of the mean platelet volume (MPV), platelet distribution width (PDW), platelet/lymphocyte ratio (PLR), and platelet values for predicting mortality in patients with sepsis. Materials and Methods: This is a retrospective study, involving patients 18 years and above who were diagnosed with sepsis. Blood samples were analyzed for platelets characteristics (counts, MPV, PDW, and PLR). The patients were separated into two groups namely the survivors and deceased. The two groups’ MPV, PDW, PLR, and platelet counts which were considered to have an effect on mortality, were compared. Results: Three hundred and thirty patients who were diagnosed with sepsis in our emergency department and complying with the study participation criteria were studied retrospectively. Comparison of the MPV, PDW, PLR, and platelet counts of the deceased and survivors showed that the MPV, PDW, and PLR were higher in the deceased while the platelet counts were higher in the survivors. Conclusion: The low number of platelets in patients with sepsis at the moment of application and the high PDW and PLR values are valuable for predicting a high mortality.
