Research Outline

My research focuses on analyzing the current state of healthcare using medical big data, with the aim of uncovering critical issues that have been overlooked in conventional analyses. I primarily utilize existing data sources such as publicly available statistics and medical claims (receipt) data to examine regional disparities in healthcare access and generate policy-relevant insights.

Previous research topics include evaluating the impact of COVID-19 on mortality in Hokkaido and analyzing how the geographic distribution of healthcare resources affects mortality rates. I have also investigated prescription trends and influencing factors of hypnotic drug use among the elderly, as well as the prevalence and determinants of polypharmacy, using receipt data. These studies consider various demographic and clinical factors, including age, comorbidities, and types of healthcare institutions.

In addition, I conduct research from the perspective of health economics, evaluating the cost-effectiveness of novel therapeutic interventions. For example, I have assessed the economic value of newly approved drugs by applying time-driven activity-based costing (TDABC), aiming to quantify their impact on clinical workflows and healthcare expenditures.

My research integrates knowledge from public health, pharmaceutical sciences, statistics, and health economics. I emphasize empirical, interdisciplinary approaches to contribute to the development of a more equitable and sustainable healthcare system for local communities and patient populations.
