Jaffray et al reported the Children's Hospital Acquired Thrombosis (CHAT) model for hospital-acquired venous thromboembolism in a critically ill child. This can help to identify a patient who may require more aggressive therapy to prevent thromboembolism. The authors are from multiple children's hospitals in the United States.
Patient selection: critically ill child
Outcome: venous thromboembolism
Predictors (using imputed cases, Table 1):
(1) Braden Q mobility score <= 2 at 24 hours of ICU admission (OR 3.7)
(2) central venous catheter placed at ICU admission or within previous 30 days (OR 4.4)
(3) history of congenital heart disease (OR 2.9)
(4) (past history of autoimmune or inflammatory disorder) OR (infection during admission (OR 2.5)
(5) length of hospital stay prior to ICU admission >= 3 days (OR 2.5)
where:
• The Braden Q mobility score appears to the question in the Braden scale for pressure ulcers about mobility, which has responses from 1 (very abnormal) to 4 (normal). It appears that responses are no impairment (4), slight impairment (3), moderate impairment (2) and severe impairment (1).
