My primary research interest is to find interventions that accelerate recovery from critical illness. I have focused on psychiatric conditions such as depression and PTSD and I am investigating whether early administration of SSRI medications to patients with acute respiratory failure can safely prevent post-ICU depression. I am collaborating with Bernadette Longo, PhD from the Department of Rhetoric and Ayse Gurses, PhD, a systems engineer from the School of Publih Health, on a study to examine the instructional design elements of ICU protocols and to characterize the ICU adminstrative process whereby published critical care research protocols are incorporated into patient care. We have obtained funding as a Grant-in-Aid of Research, Artistry, and Scholarship from the Graduate School to visit every intensive care unit in Minnesota; obtain and characterize their critical care protocols and to conduct structured interviews with administrators and clinicians about their use of ICU protocols.
I also am a co-investigator in two clinical trials being performed in the Medical ICU at the University of Minnesota Medical Center:
1. Music therapy to decrease sedative exposure during mechanical ventilation
2. Patient-controlled sedation for mechanically-ventilated patients
I am also an active member of the Academic Health Center's Center for Excellence in Critical Care, http://www.pharmacy.umn.edu/centers/cecc/home.html that participated in a peer-institution network that jointly implemented ventilator weaning and sedation reduction protocols.
