Predictors of intracranial pressure monitor use

	Intracranial Pressure Measured
	Yes No. (%)	No No. (%)	RR (95% CI)
Age, yrs
≤1	15 (60.0)	94 (84.7)	0.4 (0.2–0.7)
>1	10 (40.0)	17 (15.3)
Received cardiopulmonary resuscitation
Yes	13 (48.0)	28 (25.2)	2.5 (1.2–5.0)
No	12 (52.0)	82 (73.9)
Missing	0	1 (0.9)
Race
White	12 (52.0)	54 (48.6)	0.9 (0.4–2.0)
Other	13 (48.0)	57 (51.4)
Injury type
Inflicted	11 (44.0)	53 (47.7)	0.9 (0.4–1.8)
Noninflicted	14 (56.0)	58 (52.3)
Glasgow Coma Score of ≤8
Yes	18 (72.0)	36 (32.4)	2.2 (1.5–3.2)
No	7 (28.0)	75 (67.6)

RR, relative risk; CI, confidence interval.

Odds of receiving an intracranial pressure monitor if ≤1 yr compared with 1–2 yrs of age, controlling for if ever received cardiopulmonary resuscitation, race, and Glasgow Coma Score of ≥8, is 0.2 (95% CI, 0.1– 0.6). Adding inflicted injury into the model does not change the estimate by ≥10%.
