目的
2
针对住院药房单剂量调剂中药品检测机对“同形异谱”药品存在识别盲区的问题,构建基于图像识别初筛与拉曼光谱确证的药品双重核对系统。
方法
2
建立涵盖296种口服药品的图像和拉曼光谱数据库,基于余弦相似度算法(判定阈值0.95)进行光谱匹配;构建“图像特征初筛-拉曼光谱确证”双重核对系统,采用前后自身对照研究,在5个临床病区开展应用效果评价。
结果
2
构建的双重核对系统对库内药品的平均识别准确率为99.2%,对“同形异谱”代表性品种可实现100%准确鉴别。试验组(图像识别+拉曼光谱确证核对)单包药品平均核对耗时较对照组(图像识别+人工肉眼实物比对)缩短31.5%~43.3%(
P
<0.001);护士对试验组操作便捷性、识别效率、核对置信度及心理压力缓解维度的满意度均显著优于对照组(
P
<0.01)。
结论
2
“图像特征初筛-拉曼光谱确证”双重核对系统可有效突破传统机器视觉的技术瓶颈,在保障用药安全的同时能显著提升工作效率和工作人员满意度。
OBJECTIVE
2
To construct a dual-verification system integrating image pre-screening and Raman spectroscopy for inpatient pharmacy unit-dose dispensing in response to the issue of recognition blind spots for drugs of “same appearance but different spectrum” by drug inspection machines.
METHODS
2
An image feature and Raman spectroscopy database, covering 296 oral medications, were established. Spectral matching was performed using a cosine similarity algorithm (decision threshold 0.95). A dual-verification system of “image pre-screening and Raman spectroscopy confirmation” was designed, and a self-controlled before-and-after study was conducted across 5 clinical wards.
RESULTS
2
The system achieved a mean recognition accuracy of 99.2% for all medications in the database, with 100% accurate identification of representative “same-appearance but different-spectrum” drugs. The average verification time per-unit in the experimental group (image recognition+Raman spectroscopy confirmation and verification) was reduced by 31.5%-43.3%, compared with the control group (image recognition+manual visual comparison with actual objects)(
P
<0.001). Nurses’ satisfaction scores in the dimensions of operational convenience, identification efficiency, verification confidence, and psychological stress relief in the experimental group were all significantly superior to those of the control group (
P
<0.01).
CONCLUSIONS
2
The dual-verification system of “image pre-screening and Raman spectroscopy confirmation” effectively overcomes the technical limitations of conventional machine vision. It enhances work efficiency and staff satisfaction while ensuring medication safety.
