Hardart and Fackler identified risk factors for intracerebral hemorrhage (ICH) in neonates receiving extracorporeal membrane oxygenation (ECMO). The authors are from Children's Hospital Boston and Johns Hopkins University.
NOTE: The risk score is not described in the original reference.
Parameters:
(1) gestational age in weeks
(2) arterial pH

where:
• The point assignment is based on dividing the odds ratio by 1.6.
total score =
= SUM(points for all 5 items)
Interpretation:
• minimum risk score: 0
• maximum risk score: 10.5
• The higher the risk score the greater the risk of intracerebral hemorrhage.
