Abstract

Background: Physical activity monitors (PAMs) allow patients to track multiple health parameters and may be helpful tools to assess patient’s physical recovery after kidney transplant (KT). We performed a pilot study to quantify early postoperative physical activity after KT. Methods: Adult KT candidates were screened prospectively for inclusion and provided with a PAM (Fitbit® Inspire 2) for the first 30 days after KT. Patients who did not speak English and had undergone multi-organ transplants were excluded. Several frailty tests were performed prior to KT and on post-operative day 30: Fried Frailty Phenotype and 6-minute walk test. Results: 14 patients were enrolled since February 2021 with baseline characteristics described in Table 1. There was a significant difference in the average daily steps during the 1st week compared to the 4th week after KT (Week 1: 3200 steps vs. Week 4: 6978 steps, p<0.001). The number of steps during the first 30 days after KT correlated negatively with hospital length of stay (r -0.53,p=0.02). There was no difference in the average daily steps between pre-frail and non-frail patients [Figure 1A]. Having a post-operative complication (Clavien grade 1-3: n=5) significantly dropped the average daily steps for the first 30 days after KT (complication 6811 steps [SD 2810] vs. no-complication 2275 steps [SD 740];p=0.009) [Figure 1B]. Conclusion: PAM effectively captures post-operative biophysical parameters and can be successfully implemented to monitor patient’s recovery after KT.
