Abstract
The daily influx of patients at emergency departments (EDs) is highly unpredictable and a major cause of overcrowding in hospitals. This study aims to provide decision-making support and establish a shared situational awareness among medical and administrative personnel. By accurately forecasting daily attendance, this project attempts to effectively reduce overcrowding issues and improve overall patient care. To address this issue, this study focuses on studying different models to predict the number of visits to the emergency departments and investigating the factors affecting daily demand. Hospitals can benefit from accurately forecasting the number of patients arriving at the ED, allowing for early planning and mitigating overcrowding. As the subject of the study, a real database collected from Asunción Klinika from 2004 to 2022 was examined in Tolosa, Gipuzkoa. For this purpose, models such as ARIMA, LSTM and GRU are proposed. The study revealed that weekly patterns as well as calendar and meteorological information have an impact on the volume of daily patient arrivals. Over the years, several forecasting models using time series analysis have been proposed to address this challenge. Results showed that hybrid models outperformed the others in terms of the Mean Absolute Error metric (MAE). Predictions have yielded an average daily error of 5.2 individuals, which accounts for 13\(\%\).
