Objective. Telephone triage programs are becoming very common at children's
hospitals across the nation. One of the proposed benefits of these program
s is the more efficient use of health care resources by triaging patients t
o the appropriate level of health care. The purpose of this study is to exa
mine the appropriateness of referrals to a pediatric emergency department (
ED) by the Pediatric Health Information Line (PHIL), a hospital-based telep
hone triage program, versus all other sources of referrals.
Methods. A blinded Delphi rating system was used to review the physician's
sheets of 133 consecutive ED referrals by PHIL for medical appropriateness.
A total of 260 randomly selected control patients seen in the ED during th
e same period were similarly reviewed. If 2 of 3 pediatric emergency medici
ne physicians agreed that an ED visit was appropriate, then it was consider
ed appropriate. A comparison of the 2 groups' ED appropriateness was made u
sing a contingency table chi(2) test. An odds ratio with confidence limits
was also calculated. Demographic data were collected for both groups includ
ing age, race, gender, and insurance status.
Results. The PHIL group had an appropriateness rate of 80.2%, compared with
60.5% for the control group (chi(2) = 14 6369; odds ratio = 2.65; 95% conf
idence interval [1.5759,4.5008]).
Conclusions. This demonstrated that for the period studied, PHIL referrals
to the ED had a 33% higher rate of appropriateness than controls. This evid
ence supports telephone triage as an efficient gatekeeper for health care r
esources.
