The climate crisis is the existential challenge of our times. Informatics plays an important role in helping us understand and cope with the effects of the climate crisis on human and planetary health.

Research Scientist, Clem McDonald Center for Biomedical Informatics, Regenstrief Institute
Program Director, Learning Health Informatics Program, Regenstrief Institute
Professor of Biomedical Informatics, Indiana University School of Medicine

Dr. Titus Schleyer leads the Learning Health Informatics Program, which is focused on using everyday patient care data to improve the health and healthcare of people in Indiana and beyond. A key focus of the program is mitigating or adapting to the climate crisis, and its effect on human health. Dr. Schleyer recently launched a study of the effects of changes in air quality in Indiana on multiple medical conditions.

Other projects include

an award-winning software application that helps emergency medicine clinicians at IU Health obtain relevant information about their patients from Indiana’s health information exchange more efficiently and effectively than previously possible;
optimally using medications to help diabetic patients control their blood glucose levels;
helping close the gap in cardiovascular morbidity and mortality between black and white prostate cancer patients; and
screening data in electronic health record databases to identify health disparities at scale.

An award-winning educator, Dr. Schleyer is focused on educating the next generation of biomedical informaticians. He co-directs the National Library of Medicine funded Indiana Public & Population Health Informatics Fellowship. He also mentors fellows in three other training programs.

Dr. Schleyer holds DMD and PhD degrees from the Goethe University in Frankfurt, Germany, and DMD and MBA degrees from Temple University in Philadelphia, Pennsylvania.

Featured Projects

Air quality in Indiana and its effect on health conditions

(National Science Foundation)

Role: Principal Investigator

Air quality has effects on multiple health conditions, such as asthma, chronic obstructive pulmonary disease and cardiovascular disease. This study will examine electronic health record data over a 7-year period to evaluate the effect of improvement (e.g. due to COVID-19) or deterioration (e.g. the 2023 Canadian Wildfire Smoke Cloud) in air quality on health.

Health Dart

(AHRQ)

Role: Principal Investigator

Health Dart directly and seamlessly integrates data from the Indiana Network for Patient Care into Cerner to facilitate emergency medicine clinician access to relevant external information. It has been proven to increase use of information from Indiana’s health information exchange in all 15 IU Health emergency departments.

Treatment disparities in Type 2 Diabetes: A novel application of organizational decision support

(Regenstrief)

Role: Principal Investigator

This project examines potential disparities among under-resourced populations in prescribing for Type 2 Diabetes (T2D). It analyzes large numbers of medication decisions by clinicians to determine which decisions could have been improved. Our findings will enable targeted planning for how to ameliorate or eliminate disparities in the treatment of T2D.

Development and initial evaluation of a generalizable healthcare quality disparities screening tool

(IU Health)

Role: Principal Investigator

While healthcare disparities based on race and/or ethnicity are very common, most healthcare providers and organizations cannot easily identify and quantify those disparities specifically and efficiently in their own patient populations. This project proposes to build and evaluate a generalizable software tool that screens electronic health record data systematically and comprehensively for evidence of disparities. The tool will help healthcare organizations understand the nature and extent of disparities in their populations, and allow them to target their resources to address them more effectively and efficiently than currently possible.
