*Purpose: Activity Measure for Post-Acute Care (AM-PAC) is a tool utilized to assess three functional domains: basic mobility, daily activities, and applied cognition. Previous studies have suggested that 6-Clicks, a shorthand form of AM-PAC, strengthens a practitioner’s ability to make reliable discharge recommendations and predict hospital length of stay (LOS). The purpose of this study was to examine the correlation between AM-PAC scores (collected by both a physical therapist (PT) and an occupational therapist (OT) to LOS and discharge disposition in liver transplant patients.

*Methods: A single-center retrospective chart review was conducted on patients that underwent a liver transplant from May 2019 – May 2020. All pediatric patients were excluded. Resource utilization was defined in the study as LOS and discharge disposition.

*Results: Our analysis included data from 128 patient records. Liver transplant alone occurred in 117 patients, while 11 underwent liver and kidney transplants. The mean values for each score were 14.5 (PT AM-PAC score) and 16.8 (OT AM-PAC score). There was a negative correlation between LOS and PT Score (correlation coefficient -0.336, p<0.001) and OT score (correlation coefficient -0.398, p<0.001). There was a statistically significant difference in the mean score for each of the values based on the patients’ disposition at the time of discharge (home vs. rehab respectively). PT AM-PAC score (16 vs 13, p=0.008 ) and OT AM-PAC score (18 vs. 15, p<0001).

*Conclusions: Our results suggest that lower AM-PAC Scores are associated with higher resource utilization in liver transplant patients. Thus, AMPAC scores may help predict discharge dispositions and length of hospital stay. This is the first study that validates the AMPAC score as a predictor for patient outcomes in transplant therapy.
