The impact of a nursing triage line on the use of emergency department services in a military hospital.

The purpose of this study was to evaluate the impact of nursing telephone triage on the appropriateness of emergency department (ED) use among 563 patients at a military hospital by comparing 286 ED patients referred by the Tel-a-Nurse Line (TAN) with 277 non-TAN-referred patients from October 2000 to November 2000. When controlling for confounding factors, TAN-referred patients had less appropriate ED use than non-TAN-referred patients, although this was not statistically significant (odds ratio = 0.87, p = 0.
