Construction on medication verification system based on the integration of image recognition and Raman spectroscopy
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.
