Introduction
With the social and economic progress, pharmaceutical care in hospitals has gradually developed, starting from the initial basic services, like dispensing and standardizing the use of drugs, to the present ”patient-centered” comprehensive pharmaceutical professional and technical knowledge service. Therefore, it is necessary to dig deeper into the greatest value of pharmaceutical professionals. From the original basis, the practice scope of pharmacists began to develop in the direction of individual and comprehensive pharmaceutical care, which makes hospital pharmacists have the advantages of talents, location, technical information and combination of medicine, and enables pharmacists to provide patients with high-quality and efficient pharmaceutical care. In view of the fact that pharmacists have received more and more attention in the medical process, the analysis of the specific role of pharmacists in hospital pharmaceutical care will help to improve the overall level of the whole medical team of doctors, nurses, pharmacists and other professional and technical personnel, and bring high-quality and efficient treatment results for patients [1]. We intend to elaborate on the safety, effectiveness and economy of drugs in the process of clinical use, so as to evaluate whether pharmacists give full play to their professional functions and achieve the purpose of rational clinical use of drugs [2].
