Hospital costs continue to rise unsustainably. Up to 20% of care is wasteful including low value care (LVC). This study aimed to understand whether electronic medical record (EMR) alerts are effective at reducing pediatric LVC and measure the impact on hospital costs.
Using EMR data over a 76-month period, we evaluated changes in 4 LVC practices following the implementation of EMR alerts, using time series analysis to control for underlying time-based trends, in a large pediatric hospital in Australia. The main outcome measure was the change in rate of each LVC practice. Balancing measures included the rate of alert adherence as a proxy measure for risk of alert fatigue. Hospital costs were calculated by the volume of LVC avoided multiplied by the unit costs. Costs of the intervention were calculated from clinician and analyst time required.
All 4 LVC practices showed a statistically significant reduction following alert implementation. Two LVC practices (blood tests) showed an abrupt change, associated with high rates of alert adherence. The other 2 LVC practices (bronchodilator use in bronchiolitis and electrocardiogram ordering for sleeping bradycardia) showed an accelerated rate of improvement compared to baseline trends with lower rates of alert adherence. Hospital savings were $325 to $180 000 per alert.
EMR alerts are effective in reducing pediatric LVC practices and offer a cost-saving opportunity to the hospital. Further efforts to leverage EMR alerts in pediatric settings to reduce LVC are likely to support future sustainable healthcare delivery.
医院成本持续不可持续地上涨。多达 20%的医疗服务是浪费的,包括低价值的医疗服务(LVC)。本研究旨在了解电子病历(EMR)警报是否能有效减少儿科 LVC,并衡量其对医院成本的影响。
我们使用 EMR 数据在 76 个月的时间内,评估了澳大利亚一家大型儿科医院在实施 EMR 警报后,4 种 LVC 实践的变化情况,使用时间序列分析来控制潜在的基于时间的趋势。主要观察指标是每种 LVC 实践的变化率。平衡措施包括作为警报疲劳风险代理的警报遵守率。医院成本是通过避免的 LVC 量乘以单位成本来计算的。干预成本是根据临床医生和分析师所需的时间计算的。
所有 4 种 LVC 实践在实施警报后均显示出统计学意义上的减少。2 种 LVC 实践(血液检查)显示出突然的变化,与高比例的警报遵守率有关。其他 2 种 LVC 实践(毛细支气管炎中支气管扩张剂的使用和睡眠心动过缓时心电图的医嘱)与基线趋势相比,显示出加速改善的趋势,警报遵守率较低。医院节省了每个警报 32.5 美元至 18 万美元。
EMR 警报可有效减少儿科 LVC 实践,并为医院提供节省成本的机会。进一步努力利用 EMR 警报在儿科环境中减少 LVC,可能有助于未来可持续的医疗保健服务。
