This depends on the degree of information technology in the hospital, some hospitals have begun to use bar code management on registration. For example, the inpatient service with a bar code on the wristband management of patients, the pharmacy with a bar code to manage the distribution of drugs, because the drugs themselves have a bar code, but the inpatient distribution of drugs to be unpacked, behind the need to print their own bar code to distinguish between drugs.
The key still depends on the size of the hospital and the degree of informationization.
