Growing numbers of allogeneic stem cell transplants (HSCT) and improved post-transplant care have led to an increase of individuals with chronic graft versus host disease (cGVHD). Although cGVHD leads to functional impairment for many, there is limited literature regarding the benefits of acute inpatient rehabilitation for cGVHD patients.
To assess Functional Independence Measure (FIM) outcomes of cGVHD patients during acute inpatient rehabilitation, and to compare inpatient rehabilitation outcomes to burn patients, a rehabilitation patient population with similar co-morbidities.
Retrospective chart review.
Acute rehabilitation center at a large academic medical center.
37 adult patients with cGVHD and 30 with burn injuries admitted to inpatient rehabilitation from 2010-2015.
Linear regression analysis to evaluate group (cGVHD vs. burn) differences in functional gains. Effect size and minimal detectable change (MDC90) were used to evaluate change in FIM outcomes.
Total FIM gain, motor FIM gain, and FIM efficiency.
cGVHD patients had statistically significant lower functional gains than burn patients, with an average of 11.66 fewer total FIM points (p < .001), 10.54 fewer motor FIM points (p = .01), and 2.45 units less of FIM efficiency (p = .01). At the time of discharge, 7 (18%) patients with cGVHD exceeded the MDC90 values for total FIM gain vs. 9 (30%) patients with burn injuries (p = .26). Eight (21%) patients with cGVHD exceeded the MDC90 for motor FIM gain vs. 13 (43%) patients with burn injuries (p = .048). Effect sizes for cGVHD and burn patients were moderate to large, respectively, with burn patients having nearly twice the magnitude of gains as cGVHD patients.
Despite achieving more modest functional gains than patients with burn injuries, patients with cGVHD improved in function after acute inpatient rehabilitation. If replicated in larger studies, patients with functional impairment from cGVHD can be considered for inpatient rehabilitation. Future work should also determine minimal clinically important differences in function gain from inpatient rehabilitation for cGVHD patients.
