The effect of an automated drug-dispensing system on medication error rates was studied. Disguised observations were made on nursing units just before (phase 1) and two months after (phase 2) the implementation of Medstation Rx (Pyxis, San Diego, CA) at a 600-bed hospital. Information gathered included the time of drug administration, the time the medication as ordered to be given, a description of what happened during administration of the dose, and the type of medication error, if any. During phase 1 there were 873 observations and 148 medication errors, for an error rate of 16.9%. During phase 2 the error rate was 10.4% (97 errors in 929 observations). In both study phases, most of the errors were wrong-time errors. The mean +/- S.D. difference between actual and scheduled administration times was 34.5 +/- 48.9 minutes in phase 1 and 30.1 +/- 31.6 minutes in phase 2. Both the decrease in the error rate and the decrease in the departure from scheduled administration times were statistically significant. Medstation Rx was associated with a reduction in the rate of medication errors at a large hospital.
研究了自动发药系统对用药错误率的影响。在一家拥有600张床位的医院，于Medstation Rx（Pyxis公司，加利福尼亚州圣地亚哥）实施前（第1阶段）和实施两个月后（第2阶段），对护理单元进行了隐蔽观察。收集的信息包括给药时间、医嘱给药时间、给药过程中发生的情况描述以及用药错误类型（如有）。在第1阶段，共进行了873次观察，发生148次用药错误，错误率为16.9%。在第2阶段，错误率为10.4%（929次观察中有97次错误）。在两个研究阶段，大多数错误都是给药时间错误。第1阶段实际给药时间与预定给药时间的平均±标准差差值为34.5±48.9分钟，第2阶段为30.1±31.6分钟。错误率的降低以及与预定给药时间偏差的减小均具有统计学意义。Medstation Rx与一家大型医院用药错误率的降低相关。
