Excellence Award (Clinical Research Category) Recipient’s Remarks
Shun Yamashita, MD
Saga University Hospital
I would like to express my gratitude for selecting my research entitled “External validation of a clinical prediction model for infective endocarditis among patients with undiagnosed fever: A multi-center retrospective study” as an award for excellence in the section of Clinical Research at the American College of Physicians (ACP) Japan chapter annual meeting & lecture session 2023. I have seen that many notable doctors received various awards at the same annual meeting. I have kept in mind “one day, I want to achieve an award the meeting, too”, with yearning and awe for the award at the same meeting. It is my great pleasure to be selected to the award for excellence, making me feel as if I could have also joined in one of such doctors.
It can be difficult to diagnose Infective endocarditis (IE), the subject of this study. I have experienced many IE cases as follows: a case with disturbance of consciousness after surgery, who was diagnosed with IE after a short while; a case that could be diagnosed only by open-heart surgery; and cases that it became difficult to diagnose with IE due to the administration of antibiotics prior to obtaining blood culture samples. Among them, a case with a bad experience for me was included. I believe that the difficulty of diagnosing IE is owing to lack of the measures to estimate the probability of IE as early as possible after the patient’s admission, making the difference between doctors of the decision whether IE can be suspected in clinical settings. Therefore, we conducted a single-center study at a university hospital in Japan as a previous study and developed a prediction model for IE using only indicators that can be easily obtained even at hospitals without advanced medical equipment. In this study at four university hospitals, the external validation of the model also showed the excellent accuracy. In the future, I would like to clarify whether our model can be applied to multiple institutions, including community hospitals in Japan.
The quality of all research, presented as candidates for the Kurokawa Award other than my research, were very high. The question-and-answer sessions in English by those presenters were also excellent and overwhelmed me. I am very grateful to have been given such a honorable opportunity. I would also like to express my gratitude for the following hospitals joined in this research team: the Department of Diagnostic and Generalist Medicine, Dokkyo Medical University; the Department of General Medicine, Faculty of Medicine, Juntendo University; and the Department of General Medicine and Emergency Care, Toho University School of Medicine, Omori Hospital. I will continue to devote myself to contribute to improve the quality of future medical care. Thank you very much.
