Abstract: Objective To explore how to improve the quality of prescription by prescription intervention in the mental hospital outpatient pharmacy. Methods The retrospective study was used to analyze all the intervened prescriptions from January 2016 to December 2017 in hospital outpatient pharmacy, and the unreasonable prescriptions were classified and evaluated to analyze the cause of error and improve measures. Results A total of 683 cases of prescription interventions were conducted from 2016 to 2017, and the unreasonable prescription rate of intervention decreased from 2.21‰ in 2016 to 1.15‰ in 2017 (χ2 =36.313, P <0.05). The composition difference of unreasonable prescriptions in 2016 and 2017 was statistically significant (χ2 =20.599, P <0.05). In 2016, the success rate of prescription interventions was 79.1%, and in 2017, it was 84.7%. The difference in success rate of interventions between two years was not statistically significant (χ2 =3.230, P =0.072). Conclusion Through the joint development of real-time interventions and administrative interventions, prescription interventions have achieved certain success and the quality of prescriptions has been improved significantly.
