- Thrombocytopenia is a condition characterized by abnormally low levels of platelets, also known as thrombocytes, in the blood. It is the most common coagulation disorder among intensive care patients and is seen in 20% of medical patients and a third of surgical patients. A normal human platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Values outside this range do not necessarily indicate disease. One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000 per microliter. Thrombocytopenia can be contrasted with the conditions associated with an abnormally high level of platelets in the blood: thrombocythemia (when the cause is unknown), and thrombocytosis (when the cause is known).

Other exclusion criteria were history of platelet disorders (e.g., idiopathic thrombocytopenia purpura, congenital thrombocytopenia, hypersplenism), hematologic malignancies, use of chemotherapy (in the last 30 days prior to admission), mechanical heart valves, alcohol abuse, and hepatic cirrhosis. ...
  ... Thrombocytopenia was defined as having a platelet count of <150 × 103/μL (based on the hospital laboratory’s reference range and from published literature) [8, 16]. If more than one platelet value is available for a day, the lowest value was used. Severity of thrombocytopenia was classified into the following categories on the basis of nadir platelet count [8]: mild 101–149 × 103/μL, moderate 51–100 × 103/μL, severe 21–50 × 103/μL, and very severe ≤20 × 103/μL. ...
