论文摘要
急诊部门（EDS）是葡萄牙国家卫生服务局的基本要素，可作为具有多样化和非常严重医疗问题的用户的切入点。由于ED的固有特征；预测使用服务的患者数量特别具有挑战性。富裕与医疗专业人员的数量之间的不匹配可以导致提供的服务质量下降，并造成对整个医院产生影响的问题，并从其他部门征求医疗保健工作者和手术后。尽管没有医疗紧急情况，但不紧迫的患者驱动了ED人满为患的人满为患，该患者却诉诸紧急服务，几乎占每日患者总数的一半。本文描述了一种新颖的深度学习体系结构，即时间融合变压器，该结构使用日历和时间序列协变量预测预测间隔和点数预测为4周。我们得出的结论是，可以预测葡萄牙健康区域（HRA）（HRA）的平均绝对百分比误差（MAPE）和均方根误差（RMSE）为84.4102人/天的平均绝对百分比误差（MAPE）。本文显示了支持使用静态和时间序列协变量的多元方法的经验证据，同时超越了文献中常见的其他模型。
Emergency Departments (EDs) are a fundamental element of the Portuguese National Health Service, serving as an entry point for users with diverse and very serious medical problems. Due to the inherent characteristics of the ED; forecasting the number of patients using the services is particularly challenging. And a mismatch between the affluence and the number of medical professionals can lead to a decrease in the quality of the services provided and create problems that have repercussions for the entire hospital, with the requisition of health care workers from other departments and the postponement of surgeries. ED overcrowding is driven, in part, by non-urgent patients, that resort to emergency services despite not having a medical emergency and which represent almost half of the total number of daily patients. This paper describes a novel deep learning architecture, the Temporal Fusion Transformer, that uses calendar and time-series covariates to forecast prediction intervals and point predictions for a 4 week period. We have concluded that patient volume can be forecasted with a Mean Absolute Percentage Error (MAPE) of 5.90% for Portugal's Health Regional Areas (HRA) and a Root Mean Squared Error (RMSE) of 84.4102 people/day. The paper shows empirical evidence supporting the use of a multivariate approach with static and time-series covariates while surpassing other models commonly found in the literature.
