摘要:

我们考虑预测单个医院站点的每日住院COVID-19患者人数的问题,以帮助管理人员进行物流和规划。我们开发了几个候选的分层贝叶斯模型,直接捕捉计数性质的数据通过广义泊松似然,模型时间序列的依赖性,通过自回归和高斯过程潜在的过程,并在相关的网站共享统计强度。我们在美国马萨诸塞州的8家医院和英国的10家医院的公共数据集上展示了我们的方法。进一步的前瞻性评估将我们的方法与3家相关医院的利益相关者目前使用的基线进行了比较,通过重新调整州一级的预测来预测未来2周的需求。

英文摘要:

We consider the problem of forecasting the daily number of hospitalized COVID-19 patients at a single hospital site, in order to help administrators with logistics and planning. We develop several candidate hierarchical Bayesian models which directly capture the count nature of data via a generalized Poisson likelihood, model time-series dependencies via autoregressive and Gaussian process latent processes, and share statistical strength across related sites. We demonstrate our approach on public datasets for 8 hospitals in Massachusetts, U.S.A. and 10 hospitals in the United Kingdom. Further prospective evaluation compares our approach favorably to baselines currently used by stakeholders at 3 related hospitals to forecast 2-week-ahead demand by rescaling state-level forecasts.
