Objectives: 

To assess risk factors for electronic prescription errors in a PICU.

Design: 

A database of electronic prescriptions issued by a computerized physician order entry with clinical decision support system was analyzed to identify risk factors for prescription errors.

Measurements and Main Results: 

Of 6,250 prescriptions, 101 were associated with errors (1.6%). The error rate was twice as high in patients older than 12 years than in patients children 6–12 and 0–6 years old (2.4% vs 1.3% and 1.2%, respectively, p < 0.05). Compared with patients without errors, patients with errors had a significantly higher score on the Pediatric Index of Mortality 2 (–3.7 vs –4.5; p = 0.05), longer PICU stay (6 vs 3.1 d; p < 0.0001), and higher number of prescriptions per patient (40.8 vs. 15.7; p < 0.0001). In addition, patients with errors were more likely to have a neurologic main admission diagnosis (p = 0.008) and less likely to have a cardiologic diagnosis (p = 0.03) than patients without errors.

Conclusions: 

Our findings suggest that older patient age and greater disease severity are risk factors for electronic prescription errors.

小儿重症监护患者电子处方错误的危险因素。

目标： 

评估PICU中电子处方错误的风险因素。

设计： 

分析了由具有临床决策支持系统的计算机医生订单条目发布的电子处方数据库，以识别处方错误的风险因素。

测量和主要结果： 

在6,250张处方中，有101张与错误相关（1.6％）。12岁以上患者的错误率是6-12岁和0-6岁儿童的错误率的两倍（分别为2.4％，1.3％和1.2％，p <0.05）。与没有错误的患者相比，有错误的患者在儿童死亡率指数2上的得分显着更高（–3.7 vs –4.5；p = 0.05），PICU住院时间更长（6 vs 3.1 d；p <0.0001）和更高的数字每位患者的处方数（40.8比15.7；p <0.0001）。此外，患者的错误更可能具有神经主入院诊断（p = 0.008）和不太可能有一个心源性诊断（p = 0.03）比没有错误的患者。

结论： 

我们的发现表明，患者年龄较大和疾病严重程度较高是电子处方错误的危险因素。
