We hypothesize that the number of patients who leave without being seen is correlated with the simple-to-use National Emergency Department Overcrowding Scale (NEDOCS).
Results of a 6-item ED overcrowding scale (NEDOCS) were collected prospectively over a 17-day study period. The following additional data were extracted from records for each 2-hour study period: (1) number of registered patients, (2) number of ambulances that arrived, and (3) number of patients signed in that hour who eventually left without being seen. Spearman correlation coefficients were computed for the leaving without being seen (LWBS) rate with the NEDOCS score at the time of patient presentation and 2, 4, and 6 hours later.
The study period represents two hundred fourteen 2-hour periods. The LWBS rate was determined for 100% of the times; NEDOCS scores were determined for a sampling of 62% of the times spread equally over all hours of the day and days of the week. Correlation between the NEDOCS score and LWBS was 0.665.
The NEDOCS score is well correlated with LWBS.
我们假设未就诊即离开的患者数量与易于使用的国家急诊科拥挤度量表（NEDOCS）相关。
在为期17天的研究期间前瞻性收集了一个6项急诊科拥挤度量表（NEDOCS）的结果。从每个2小时研究时间段的记录中提取以下额外数据：（1）登记患者数量，（2）到达的救护车数量，以及（3）该小时内最终未就诊即离开的签到患者数量。计算患者就诊时以及2、4和6小时后未就诊即离开（LWBS）率与NEDOCS评分之间的Spearman相关系数。
研究期间包括214个2小时时间段。100%的时间段确定了LWBS率；在一天中所有小时和一周中各天均匀分布的62%的时间段抽样确定了NEDOCS评分。NEDOCS评分与LWBS之间的相关性为0.665。
NEDOCS评分与LWBS密切相关。
