Lee et al developed the Transport Risk Index of Physiologic Stability (TRIPS) to evaluate newborn infants requiring emergency transport. This can help identify those infants who are greatest risk of mortality. The authors are from the University of British Columbia, Dalhousie University and other institutions in Canada.
Parameters:
(1) temperature
(2) respiratory status
(3) systolic blood pressure
(4) response to noxious stimuli

• The values for systolic blood pressure seem pretty low.
total TRIPS score =
= SUM(points for all 4 parameters)
Interpretation:
• minimum score: 0
• maximum score: 65
• The higher the TRIPS the higher the mortality rate.
