目的:利用資訊科技，以變動式顏色呈現病人之檢傷級數於急診電腦診間醫令系統，有效改善急診病患等候醫師看診時間。方法:依檢傷級數給予不同之合理等候時間範圍，呈現在急診電腦診間醫令系統之等候名單上作為不同之背景顏色。隨著等候時間增加，顏色會依「尚餘合理等候時間」變動(由白色漸轉變至紅色)。結果:平均等候看診時間在此方法實施後比實施前有明顯降低(由8.5±7.0min降至7.0±5.6 min，P < 0.001) 。邏輯斯迴歸發現此資訊科技方法的實施、檢傷級數、年齡、來院時段、主要看診醫師、系統內仍治療中之病患人數均能預測等候醫師看診時間。此方法實施後，急診患者等候醫師看診時間超過15分鐘之勝算比為0.65的，其他會降低等候醫師看診時間超過15分鐘之情形為檢傷三級、65歲以上、及主要由主治醫師看診的病 患。如果在系統內有超過八位病患仍在處置中，則等候醫師看診超過15分鍾的勝算比為4.25。結論:此方法能有效促進醫療人員與環境的溝通，縮短等候醫師看診時間，提高急診效率。

Objectives: We conducted a prospective study to determine if an information technology (IT) approach using a dynamic color labeling of the patient's acuity level in the patient encounter list of a computerized medical charting system was able to effectively decrease physician wait time. Methods: For the various different time ranges of acuity-specific remaining waiting time, we assigned corresponding background colors on the EDIS patient list. As time elapsed, the background color changed dynamically from white to red. Results: Mean patient waiting time was significantly lower for stage 2 (after intervention) patients (7.0 ± 5.6 vs. 8.5 ± 7.0 min, p ＜ 0.001) than for stage 1 (before intervention). By multivariate logistic regression analysis, we found that the patients in stage 2 had an odds ratio of 0.65 of waiting longer than 15 minutes. Patients waited longer if they were at T2 acuity level, were older than 65 years or were seen by an attending physician. Patients were 4.25 times more likely to wait longer if there were more than eight ED patients currently being treated. Conclusions: We conclude that this IT approach was useful and facilitated provider communications; it was also able to improve the efficiency/efficacy of the emergency department by shortening physician-waiting time.
