Shown below is a calculator using the predictive score for VTE among hospitalized medical patients. Check all boxes that apply to your patient:

Variable	Score
IMPROVE Bleeding Risk Score
Active gastric or duodenal ulcer	4.5
Prior bleeding within the last 3 months	4
Thrombocytopenia (<50x10⁹/L)	4
Age ≥ 85 years	3.5
Liver failure (INR>1.5)	2.5
Severe kidney failure (GFR< 30 mL/min/m²)	2.5
Admission to ICU or CCU	2.5
Central venous catheter	2
Rheumatic disease	2
Active malignancy	2
Age: 40-84 years	1.5
Male	1
Moderate kidney failure (GFR: 30-59 mL/min/m²)	1
Result:
Interpretation:

The interpretation of the score is as follows:


	Clinical manifestations	Laboratory abnormalities	Radiographic features
Legionnaires' disease	Adult respiratory distress syndrome Bronchial breath sounds Dry cough High grade fever Progressive dyspnea	Legionella urinary antigen positive Leukocytosis with relative lymphopenia Hyponatremia Hypophosphatemia	Alveolar consolidation on chest radiograph Lobar consolidation on chest radiograph
Acute interstitial pneumonia	Dry cough Progressive dyspnea	Nonspecific	Disseminated consolidation on chest radiograph Interstitial infiltrate on chest radiograph Increased uptake on gallium scan
Mycoplasma pneumonia	Dry cough Pleuritic chest pain Bronchial breath sounds Inflamed, opaque, hypomobile tympanic membrane	Lymphocytosis Cold agglutinins positive
