An oral, patient-controlled analgesia (PCA) device uses radiofrequency identification technology to allow patients direct, controlled access to medication at the bedside. Twenty oncology inpatients participated in a pilot study to evaluate the device's design function and patient, nursing, and pharmacy satisfaction. The referring oncology physicians ordered oral pain tablets or capsules on an as-needed basis; the drugs were dispensed by the device with a specified lockout time interval and with a provision for administration of an immediate dose, if desired. In all, 95% of the patients reported that use of the device provided better pain control, since it allowed them to receive medication directly without delay. Further, 100% of the patients preferred using the device to calling a nurse for each dose of as-needed medication. All patients desired to use the device again during future hospitalizations if they required oral breakthrough pain medications. More than 80% of nurses surveyed stated that the device was reliable and easy both to program and to query about medication-dispensing data. In addition, more than 90% of nurses reported that patients' pain appeared to be better controlled when the device was used; they also indicated that the device saved them nursing time. Pharmacy staff agreed that the device's disposable medication tray was easy to fill; however, it did not save them time. The results of a Cronbach's-alpha statistic calculated for patient and nursing questionnaires showed these surveys to be reliable tools that featured consistent responses. The overall conclusion from this pilot study was that the oral PCA device was a useful, functional device that should improve pain management in selected patients in the acute care setting.
一种口服患者自控镇痛（PCA）装置利用射频识别技术，使患者能够在床边直接、自主地获取药物。20名肿瘤住院患者参与了一项试点研究，以评估该装置的设计功能以及患者、护理人员和药剂师的满意度。转诊的肿瘤内科医生根据需要开具口服止痛片或胶囊；药物由该装置发放，设有特定的锁定时间间隔，并可根据需要提供立即给药的功能。总体而言，95%的患者报告称使用该装置能更好地控制疼痛，因为这使他们能够直接且及时地获得药物。此外，100%的患者表示比起每次需要用药时呼叫护士，他们更倾向于使用该装置。如果未来住院期间需要口服突破性止痛药，所有患者都希望再次使用该装置。超过80%接受调查的护士表示，该装置可靠，易于编程和查询用药发放数据。此外，超过90%的护士报告称，使用该装置时患者的疼痛似乎得到了更好的控制；他们还指出该装置节省了护理时间。药剂科工作人员一致认为该装置的一次性药盘易于装填；然而，这并没有为他们节省时间。对患者和护理人员问卷进行的克朗巴哈系数统计结果表明，这些调查是可靠的工具，具有一致的回答。这项试点研究的总体结论是，口服PCA装置是一种有用且功能良好的装置，应能改善急性护理环境中特定患者的疼痛管理。
