Background

Objective: To determine if WHR vs body mass index (BMI) could be used as a reliable predictor of increased length of stay from transplant to first discharge, defined as 7 days or more, in a group of first time kidney transplant recipients.

Background: Prolonged hospitalizations in renal transplant patients continues to be a concern due to its potential effect on health care costs and patient satisfaction scores. Various factors including BMI are considered while establishing suitability for kidney transplantation. However, BMI has its limitations as it does not take into account body fat distribution. WHR may provide an alternative tool for pre-transplant candidate selection. We aimed to assess if WHR could to be used to predict increased length of stay (LOS) post kidney transplantation.

Methods

This is a single center retrospective analysis of deceased and living donor kidney transplants performed through the period of May 2015 to March 2017. Increased LOS was defined as 7 days or more. A multivariate linear regression analysis was performed comparing BMI and WHR, and results were reviewed. A p-value of ≤ 0.05 was considered significant.

Results

A total of 69 patients were included, 60 of which received deceased donor kidney transplants and 9 received living donor kidneys. All patients were first time kidney transplant recipients. Patients WHR ranged from 0.78 – 1.07. The LOS ranged from 5 to 22 days. Increased WHR was significantly assocated with LOS (P-value = 0.04), whereas BMI was not (P-value = 0.84).

Conclusion

Our results suggest that WHR can be used as an accurate tool to predict increased length of stay in first time kidney transplant recipients. Further collaborative efforts and research are needed to fully elucidate the relationships between WHR and increased length of stay with respect to cost, patient satisfaction and graft outcomes,
