  1. Time series forecasts of emergency department patient volume, length of stay, and acuity.

    Article - En anglais

    Study hypothesis

    Time series analysis can provide accurate predictions of emergency department volume, length of stay, and acuity.

    Design

    Prospective stochastic time series modeling.

    Setting

    A university teaching hospital.

    Interventions

    All patients seen during two sequential years had time of arrival, discharge, and acuity recorded in a computer database.

    Time series variables were formed for patients arriving per hour, length of stay, and acuity.

    Prediction models were developed from the year 1 data and included five types: raw observations, moving averages, mean values with moving averages, seasonal indicators with moving averages, and autoregressive integrated moving averages.

    Forecasts from each model were compared with observations from the first 25 weeks of year 2.
