In recent years, collaborative medical care has progressed, and pharmacists have more opportunities to participate in clinical research. The main research subject that pharmacists are involved in is TDM research, which is one of the personalized medicines. In TDM studies, it may be necessary to collect blood over time, and the timing and storage status are often important. In addition, it is not uncommon to obtain patient information necessary for selecting, analyzing, and considering subjects according to the patient's condition not only from medical records but also from nursing records. Therefore, in advancing this type of research, it is thought that the quality of the research will be improved if the content and intention of the research are shared with nurses and other multidisciplinary medical staff. In this symposium, we would like to discuss the usefulness of multidisciplinary collaboration in advancing clinical research, citing cases and research that we have recently experienced.
