Liver Transplant Candidates Lower Mortality Risk Through Personalized Prehabilitation
Personalized prehabilitation programs significantly reduce frailty and lower pre-transplant mortality risk for liver transplant candidates, according to a study published on October 21 in Clinical Gastroenterology and Hepatology. The research, conducted by teams at Northwestern Medicine and the University of Pittsburgh, demonstrates that nearly two-thirds of participating patients successfully improved their frailty scores, cutting their risk of dying while awaiting an organ by roughly 50%.
Researchers tracked nearly 1,300 adults evaluated for liver transplantation between 2018 and 2022 at the University of Pittsburgh’s transplantation center. Among that group, 355 patients completed at least two follow-up visits in the prehabilitation program. Clinicians measured changes using the Liver Frailty Index, which evaluates grip strength, chair stands, and balance positions across three specific stances.
The findings revealed that 64% of the program participants improved their scores. Patients who lowered their frailty score by 0.4 points or more experienced a roughly 50% reduction in mortality risk while on the transplant waitlist. This calculation accounted for confounding variables including age, baseline frailty, and overall disease severity.
Clinical Oversight and Tailored At-Home Exercise Plans
Only about 10 transplant centers worldwide currently offer this specialized prehabilitation model. Upon referral, patients undergo immediate assessments to evaluate strength and nutritional requirements. Dr. Andres Duarte-Rojo, study senior author and transplant hepatologist at Northwestern Medicine, collaborates closely with physical therapists and dietitians to design individualized regimens.
There are precautions, of course,
Duarte-Rojo stated regarding the tailored physical exertion limits. You don’t send these patients to the gym to lift 100 pounds. You have to start low and progress slowly. But we find that the frailest ones often improve the most.
Participants receive home exercise plans that undergo adjustment during follow-up appointments scheduled every four to 12 weeks. Duarte-Rojo noted that historical resistance from the medical establishment questioned whether fragile patients with advanced liver disease could safely exercise without risking bleeding or worsened encephalopathy. The study results challenge those past assumptions by proving that physical conditioning yields measurable clinical improvements.
Steven McGowan improves status through prehabilitation program
Steven McGowan, a 62-year-old retiree from the Chicago area awaiting both a kidney and liver transplant, began participating in the Northwestern prehabilitation program in January. Initially classified as very frail during his intake evaluation, McGowan adjusted his daily routine to incorporate the prescribed fitness and dietary plans.
I was very frail when I went in,
McGowan said. I started getting stronger pretty quickly. I’m honestly surprised how much I’m doing. I’m walking three to four miles a day now.
Northwestern clinicians now categorize his physical status as strong.
What are the Liver Frailty Index tests?
What specific tests comprise the Liver Frailty Index used in the study?
The index evaluates three clinical metrics: grip strength, chair stands, and the ability to remain in three balancing positions.
How many transplant centers currently offer this prehabilitation model?
Approximately 10 transplant centers worldwide provide this personalized fitness program, with Northwestern Medicine and the University of Pittsburgh serving as participating institutions in the research.
What threshold of score improvement correlates with a lower mortality risk?
Patients who lowered their Liver Frailty Index score by 0.4 points or more achieved a roughly 50% lower risk of dying while awaiting a donor organ.
What are the broader applications for this prehabilitation approach outside of liver disease?
Study authors indicate the structured exercise and nutrition framework could potentially be replicated for patients facing cancer diagnoses and other major surgical procedures.
