After Wenchuan earthquake, the West China Second University Hospital immediately started the preparation of emergency pharmaceutical administration. The pharmaceutical department effectively controlled the provision, purchasing, utilization and donation of medications through a double-track operation system. In this way, the medication supply was ensured for both the patients suffering from the disaster and routine patients, which guaranteed the rationality in medication and promoted the utilization of the donated drugs so that more than 80 000 drug cost was saved for the hospital.
