Drug safety management team was established in 2005, and was initially set up as the "venous injury group". In 2008, it was officially renamed as the "drug safety Management team". Since its establishment, the group has been mainly responsible for the consultation of new drugs and special drugs in the hospital, so as to make clinical medication more standardized. Group discussions will be held regularly to formulate some effective measures according to the situation of drug use in our hospital, so as to ensure the safety of clinical drug use in our hospital. Each department has drug information officer, who is responsible for collecting common drugs, new drugs and special drugs of each ward and timely reporting adverse drug reactions. This group regularly releases information about the use of drugs in the hospital to facilitate the safe use of drugs in clinical wards.
