RESUMO
OBJECTIVE:To provide references for pharmaceutical workers in retrieving literatures by means of Chinese bi_omedical database(CBM),China journal full-text database(CNK) and Chinese science & technology journal database(VIP).METHDOS:With the commonly research topics of hospital pharmacy as research scope,literatures retrieved by database sampling underwent a preliminary contrast analysis and a computer-assisted automatic meta-analysis after programming.RESU_TLS:None the 3 databases indexed all the tested pharmaceutical periodicals(totaled 79 kinds).There were differences among the un-indexed periodicals, except a few are the same in kinds.The retrieved literatures of docuterm had a high proportion of repetition;however,the computer had merged the same literatures retrieved in different databases.CONCLUSIONS:The literatures indexed in the 3 databases have their own characteristics,thus literature recall ratio can only be improved by combining multiple databases.The automatic meta-analysis of the retrieval literatures can be performed by means of computer program,the repeated work can be reduced thereafter.
