: Medication errors cause adverse events; however, studies have yet to examine medication errors related to nursing hours while considering ward characteristics in Japan. Purpose: This study investigated medication errors caused by nurses to quantitatively assess ward activity as busyness in nursing duties. : This study considered patients hospitalized in the general wards of 10 National Hospital Organization institutions between April 2019 and March 2020. The study data were obtained from the Diagnosis Procedure Combination system, incident report system, and reports on nurse staffing and work hours. Data for 27,629 ward days with 88,475 patients were analyzed. Multivariate analysis was performed to determine the impact of factors on medication errors. : The mean patient age was 71.43 years (SD = 15.08). The medication error rate in nursing wards was 13.71%. The mean nursing time per patient during day shift was 1.95 h (SD = 0.58) in the non-medication error group and 2.06 h (SD = 0.58) in the medication error group ( < 0.01). The nursing time per patient in the medication error group compared to that in the non-medication error group had an odds ratio of 1.31 ( < 0.01) during day shifts. : Contrary to evidence, the results showed that medication errors caused by nurses related to increased nurse time with patients during day shifts. Further investigation is needed on the relationship of busyness with nursing duties to ensure an adequate nurse-patient ratio, nursing time, and improved patient safety.
用药错误会导致不良事件；然而，在考虑日本病房特征的情况下，尚未有研究考察与护理时长相关的用药错误。目的：本研究调查护士导致的用药错误，以定量评估病房活动，即护理工作的繁忙程度。：本研究纳入了2019年4月至2020年3月期间在10家国立医院机构普通病房住院的患者。研究数据来自诊断程序组合系统、事件报告系统以及护士人员配备和工作时长报告。对涉及88475名患者的27629个病房日的数据进行了分析。进行多因素分析以确定各因素对用药错误的影响。：患者平均年龄为71.43岁（标准差 = 15.08）。护理病房的用药错误率为13.71%。在白班期间，无用药错误组每位患者的平均护理时间为1.95小时（标准差 = 0.58），用药错误组为2.06小时（标准差 = 0.58）（<0.01）。在白班期间，用药错误组每位患者的护理时间与无用药错误组相比，优势比为1.31（<0.01）。：与证据相反，结果表明护士导致的用药错误与白班期间护士与患者相处时间增加有关。需要进一步调查护理工作繁忙程度之间的关系，以确保有足够的护患比、护理时间，并提高患者安全。
