In prescribing practice for inpatients, quickly detecting pairs of drug-drug interactions (DDIs) and providing prompt management when prescribing is of utmost importance in ensuring safe and rational use of drugs. Subjects and research methods: All prescriptions with DDIs warnings for inpatients from 1/1/2021 to 31/3/2021 on the residue reporting system at Lao Cai General Hospital. The research is designed as a cohort study. Results: In 3 months of implementing DDIs surveillance on the system of reporting, there were 214 times of DDIs occurring in 157 inpatients, of which 2 were contraindicated DDIs and 212 severe DDIs. Patients with DDIs have the mean age and number of diseases, respectively: 63.2 ± 17.5 (years) and 4.3 ± 1.87 (diseases). 2 patients with contraindicated DDIs of a clarithromycin-lovastatin pair received direct feedback from pharmacists to agree to cancel the prescription; Patients with severe DDIs are also discussed by pharmacists to agree on the most appropriate management for each patient, such as 77.83% of clinical supervision; 7.08% of replacement medicine; 2.83% of following up more tests; 1.89% of stopping using drugs. Conclusion: The DDIs warning system and clinical pharmacy activity have managed all pairs of DDIs that often occur on inpatients at Lao Cai General Hospital.
