准确预测当天出院的可能性，可以将三分之一的医疗住院病人直接送到流动护理病房，从而促进床位管理。在这项研究的第1阶段，我们确定了7个独立的因素，有助于门诊护理评分（Amb评分），可以作为一种工具，选择门诊急诊护理（AEC）患者的医疗紧急摄入量。高分与在医院评估和治疗后12小时内出院相关。在II期研究中，我们在不同的患者队列中验证并内部验证了Amb评分的性能，发现其在识别早期出院（即AEC患者）方面功能良好，接受者操作曲线下面积（AUROC）为0.91（95% CI 0.88-0.94）。Amb评分>= 5在识别潜在AEC患者方面的敏感性为96%（95%CI 90-98），特异性为62%（95%CI 55-68）。
Accurate prediction of the likelihood of same-day discharge could make it possible to direct one-third of the medical in-take to an ambulatory care unit, thereby facilitating bed management. In Phase 1 of this study, we identified seven independent factors that contribute to an ambulatory care score (Amb score) that can potentially be used as a tool to select ambulatory emergency care (AEC) patients from the medical emergency in-take. A high score was associated with discharge within 12 hours of assessment and treatment in hospital. In Phase 2, we verified and internally validated the performance of the Amb score in a different cohort of patients, finding that it functioned well in identifying early discharges (ie AEC patients), with an area under the receiver operator curve (AUROC) of 0.91 (95% CI 0.88-0.94). An Amb score of >= 5 has a sensitivity of 96% (95% CI 90-98) and a specificity of 62% (95% CI 55-68) in identifying potential AEC patients.
