The effects of management system were evaluated with the number of records for off-label drug use and pass rate of approval as indexes. RESULTS： Since the year of 2011， the management system for off-label drug use had gradually established and improved in our hospital； the mode of registration and approval for off-label drug use was established by based on a multi-disciplinary team management and quality classification for clinical evidence. Up to 2016， a total of 252 records for off-label use were submitted， among which 159 （accounting for 59.77％） were for pediatrics and 93 （accounting for 34.96％） were for gynecology and obstetrics. Among the submitted records， 181 had passed the examination and approval， and the pass rate was 64.29％. Special prescription comments indicated that the numbers of off-label use medical orders in inpatient medical orders showed a downward trend， and the proportion of recorded medical orders of off-label use had increased from 17.33％ in 2013 to 84.00％ in 2016.
