Sir,I would like to discuss on the report on “Evaluation of medicine prescription pattern.”[1] Karimi et al. concluded “there is an inevitable need to improve prescription habits among different specialties, especially among general practitioners.”[1] In fact, the problem of improper prescription is common in clinical practice and should be well-managed. Similar problems can be seen in many countries. For example, in Niger, there were “few prescriptions according to standard treatment” and becomes the urgent problem to be managed.[2] It is no doubt that the problem exists. The more important thing is the factors contributing to the prescribing behavior. Here, we would like to show the experience from China on this problem. Of interest, it was found “doctors with more education, more training on rational drug use, and better acquisition of medicine knowledge prescribe a lower percentage of generic drugs.”[3] It is suggested that education and “performance evaluation for doctors”[3] seem to be the goof way for promotion of good prescribing practice. In addition, the “economic incentives” is found to be another important factor affecting rational drug use.[4]
