Clinical decision support (CDS) displayed in electronic health records has been found to reduce the incidence of medication errors and adverse drug events (ADE). Recent data suggested that medication-related CDS alerts were frequently over-ridden, often inappropriately. Patients in the intensive care unit (ICU) are at an increased risk of ADEs; however, limited data exist on the benefits of CDS in the ICU. This study aims to evaluate potential harm associated with medication-related CDS over-rides in the ICU.
This was a prospective observational study of adults admitted to any of six ICUs between July 2016 and April 2017 at our institution. Patients with provider-overridden CDS for dose (orders for scheduled frequency and not pro re nata), drug allergy, drug-drug interaction, geriatric and renal alerts (contraindicated medications for renal function or renal dosing) were included. The primary outcome was the appropriateness of over-rides, which were evaluated by two independent reviewers. Secondary outcomes included incidence of ADEs following alert over-ride and risk of ADEs based on over-ride appropriateness.
A total of 2448 over-ridden alerts from 712 unique patient encounters met inclusion criteria. The overall appropriateness rate for over-rides was 81.6% and varied by alert type. More ADEs (potential and definite) were identified following inappropriate over-rides compared with appropriate over-rides (16.5 vs 2.74 per 100 over-ridden alerts, Fisher's exact test P<0.001). An adjusted logistic regression model showed that inappropriate over-rides were associated with an increased risk of ADEs (OR 6.14, 95% CI 4.63 to 7.71, P<0.001).
Approximately four of five identified CDS over-rides were appropriately over-ridden, with the rate varying by alert type. However, inappropriate over-rides were six times as likely to be associated with potential and definite ADEs, compared with appropriate over-rides. Further efforts should be targeted at improving the positive predictive value of CDS such as by suppressing alerts that are appropriately over-ridden.
临床决策支持(CDS)在电子健康记录中的显示已被发现可降低药物错误和药物不良事件(ADE)的发生率。最近的数据表明,药物相关的 CDS 警报经常被覆盖,而且往往是不适当的。重症监护病房(ICU)的患者发生 ADE 的风险增加;然而,关于 ICU 中 CDS 的益处的数据有限。本研究旨在评估 ICU 中与药物相关的 CDS 覆盖所带来的潜在危害。
这是一项前瞻性观察性研究,纳入了 2016 年 7 月至 2017 年 4 月期间我院六家 ICU 中收治的成年人患者。纳入了对 CDS 进行覆盖的患者,包括剂量相关的 CDS 覆盖(计划的频率而非按需给药)、药物过敏、药物相互作用、老年和肾功能警报(禁忌用于肾功能或肾功能剂量的药物)。主要结局是覆盖的适当性,由两名独立评审员进行评估。次要结局包括在警报覆盖后 ADE 的发生率以及基于覆盖适当性的 ADE 风险。
共有 712 例患者发生的 2448 次警报覆盖符合纳入标准。覆盖的总体适当率为 81.6%,且按警报类型而有所不同。与适当覆盖相比,不适当覆盖后发现了更多的 ADE(潜在和确定)(每 100 次覆盖警报分别为 16.5 和 2.74,Fisher 精确检验 P<0.001)。调整后的逻辑回归模型显示,不适当覆盖与 ADE 风险增加相关(OR 6.14,95%CI 4.63 至 7.71,P<0.001)。
约五分之四的 CDS 覆盖是适当的,且覆盖率因警报类型而异。然而,与适当覆盖相比,不适当覆盖与潜在和确定的 ADE 相关的可能性是其六倍。应进一步努力提高 CDS 的阳性预测值,例如通过抑制适当覆盖的警报。
