Sharathkumar et al developed a decision rule for predicting the risk of venous thromboembolism in a hospitalized child. The authors are from Ann and Robert H. Lurie Children's Hospital of Chicago, Northwestern University, Riley Hospital for Children, and Indiana University.
Patient selection: hospitalized pediatric patient (age range 0 to 20 years)
Outcome: venous thromboembolism
Parameters:
(1) length of stay in days
(2) direct admission to ICU
(3) central venous catheter
(4) blood stream infection
(5) immobilization
(6) birth control pills (BCP)

total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 9.5
• A score >= 3 indicates a high risk for venous thromboembolism.
Performance at cutoff:
• Sensitivity 70%, specificity 80%, AUC 0.85.
