Adaptation of Predictive Models to PDA Hand-Held Devices.

Prediction models using multiple logistic regression are appearing with increasing frequency in the medical literature. Problems associated with these models include the complexity of computations when applied in their pure form, and lack of availability at the bedside. Personal digital assistant (PDA) hand-held devices equipped with spreadsheet software offer the clinician a readily available and easily applied means of applying predictive models at the bedside.

Effect of vital signs on triage decisions.

Study Objective: We sought to determine whether knowledge of vital signs changes nurse triage designations (TDs). We also sought to determine whether patient age and ability to communicate modify the effect of vital signs on triage decisions.

Methods: We performed a prospective observational study, in 24 emergency departments, of nurse-assigned TDs of all ED patients undergoing triage.
