Healthcare Epidemiology

Yosuke Yamamoto, M.D., Ph.D. Professor 

We are conducting clinical epidemiology research to answer clinical questions about medical care and health problems. In particular, we will promote evidence to solve medical and social problems by accurately evaluating the subjective health status (e.g., health-related QoL). We also focus on research that measures and bridges the gap between that evidence and medical and social practices.

Research and Education

We are mainly engaged in clinical epidemiology research in the following four research areas.
(1) Research to measure patient’s QoL / PRO (Patient-reported outcomes) and utilize it for medical treatment
(2) Evaluation research on diagnostic methods such as development and validation of clinical prediction rules
(3) Research to investigate the actual conditions of diseases and medical care
(4) Research to elucidate the relationship between factors and medical outcomes using QoL/PRO measurements

Regarding the educational activities in SPH, we provide course work on clinical research design and methods.
(1) epidemiology II (research design)
(2) special seminar in study design I/II
(3) special seminar of data analysis
