However, in China, the training pathways and practical work of clinical pharmacy are still in the exploratory stage. In the present review, we aimed to discuss the impact of pharmacist-led interventions in reducing inappropriate drug use in orthopaedics. Results showed clinical pharmacists can assist orthopaedists and nurses in the rational use of medication in all aspects of antibiotic therapy, pain control and anticoagulation therapy. The clinical interventions by pharmacists have greatly reduced medication errors and medical costs. However, there is still a long time to develop pharmacy service, improve the professional quality of pharmacists and enact the Chinese Pharmacist Law.展开更多
