Vanderbilt Nursing Professor Receives $3.6M to Study Telemedicine and Post-intensive Care Syndrome Recovery
Vanderbilt School of Nursing Assistant Professor Leanne Boehm, PhD, RN, FCCM, received an R01 grant of more than $3.6 million over five years to examine, with her collaborators, the efficacy of telemedicine services among people recovering from post-intensive care syndrome. This effort, funded by the National Institute on Aging, is the first PICS longitudinal cognitive impairment intervention study.
The Vanderbilt-led study will build on the burgeoning national effort to unite ICU clinicians and primary care providers in providing comprehensive care for patients starting when they are discharged from the ICU and continuing through transitional outpatient care.
“Following ICU discharge, patients have problems lasting months to years that often go unaddressed,” Boehm says. “Primary care providers—and even ICU clinicians taking care of these patients—do not know much about PICS.”
PICS affects up to 80 percent of intensive care unit survivors with a range of cognitive, physical, mental, and socioeconomic impairments—which may result in a poorer quality of life for sufferers and their caregivers. Studies have found that in a broad group of adult ICU survivors in all age groups, 33 percent to 50 percent develop ICU-acquired dementia—a symptom of PICS—which the National Institutes of Health now designates as Alzheimer’s Disease and Related Dementia. The ICU Recovery Center at Vanderbilt and the Critical and Acute Illness Recovery Organization were developed to establish ICU recovery clinics that address PICS.
“Only recently have we started to characterize what PICS assessment and management looks like across ICU recovery clinics,” Boehm says. “We’re seeing so much variation in what clinics are doing. This made us wonder which screening and intervention elements were the most important in ICU recovery clinics.”
To answer these questions, Boehm and her collaborators, including Dr. Carla Sevin, director of the ICU Recovery Center and co-chair of CAIRO’s post-ICU clinic collaborative, and James Jackson, director of behavioral health at the ICU Recovery Center, have developed a telemedicine-based randomized controlled trial to assess how a structured multidisciplinary ICU recovery clinic intervention can help patients and their caregivers live healthier, happier lives. Sevin and Jackson are recognized international leaders in establishing and implementing ICU recovery clinics.
The study’s multidisciplinary intervention will convene a physician and nurse practitioner, a psychologist or psychiatrist, a social worker, and a pharmacist to evaluate patients in the domains affected by PICS—specifically, the cognitive, physical, mental health, and socioeconomic challenges. Caregivers will be assessed for PICS-family and caregiver burden.
The evaluation will result in a care plan tailored to each patient’s needs and shared with their PCP. “Providers will talk with the patient about their assessment, care plan, what they can expect, and the resources to help them in their journey,” Boehm says. “Our team, all familiar with the ICU experience, have a multidisciplinary view of ICU-started problems and serve as a bridge in the transition of care from the ICU to their PCP or specialists. Our primary aim is to see if this intervention can improve cognition, mental health, physical function, social network, and patient activation.”
The choice to make this a study of telemedicine services was considered intentional. “ICU recovery clinics tend to be at major metropolitan academic medical centers, with limited services for patients in rural settings or those with new or worsening disability,” Boehm says. “Telemedicine helps address targeted access and availability gaps in PICS assessment and management.”
The pandemic made the study’s virtual component possible by rapidly adjusting and adopting digital services. A pilot study conducted by Boehm confirmed that patients, providers, and caregiver groups could engage in telemedicine and were willing to accept care through online platforms. The pilot study also informed best practices for efficient and supportive telemedicine ICU recovery clinic assessments; mental health and socioeconomic discussions will be conducted privately, and broader physical health discussions will be with the full group of providers.
Boehm’s other collaborators include Dr. Nathan Brummel, a former clinical fellow in Pulmonary Disease and Critical Care Medicine at Vanderbilt School of Medicine, Marianna LaNoue, professor of nursing, and Joanna Stollings, a medical intensive care unit clinical pharmacy specialist at VUMC.
