What is the timing of onset, progression, and severity of the thrombocytopenia? Is the thrombocytopenia isolated, or is there concomitant anemia, leukopenia, or both? What are the findings of the peripheral blood film? What tests and studies are useful to evaluate each etiology? What is the frequency of specific causes of thrombocytopenia in defined clinical circumstances? Is the thrombocytopenia a marker of bleeding risk, thrombosis risk, or adverse prognosis? What treatments are available for each etiology?Thrombocytosis Is the thrombocytosis newly acquired during the hospitalization? Is there concomitant splenomegaly and/or abnormalities in hemoglobin or white blood cell levels? Does the thrombocytosis predate the hospitalization?
