Research Summary

Dr. Mark Siegel, the Program Director of the Traditional Internal Medicine Residency, is involved in multiple clinical research studies. For several years he has participated in multicenter clinical research trials investigating new treatments for sepsis and acute respiratory distress syndrome (ARDS), in addition to other facets of critical illness. Dr. Siegel has several ongoing research projects conducted with Yale trainees, in areas such as the management of sepsis, end-of-life decision making, and psychiatric disorders in the next-of-kin of ICU patients.

Extensive Research Description

I am interested in studying the factors that influence end-of-life decision making by ICU clinicians and the family members of critically ill patients. In conjunction with this I am interested in the emotional, religious, educational, and cognitive factors that influence how choices are made.

I also maintain a strong focus on new treatment strategies for ARDS and sepsis as well as a striving for a better understanding of the factors that underlie the pathogenesis and outcomes of critical illness.

I am also working on a project to determine the degree to which concerns about long-term dependence on life support influence patients' wishes regarding life sustaining interventions.

I am also engaged in a project focusing on the factors that drive clinicians to provide clinically ineffective interventions in the ICU.
