Disparities in telemedicine utilization among kidney transplant patients during the COVID-19 pandemic: Barriers and opportunities.

INTRODUCTION: The COVID-19 pandemic allowed for the rapid implementation of telemedicine for kidney transplant patients; however, widespread adoption may worsen existing health care inequities among vulnerable populations. This study aimed to characterize telemedicine utilization by kidney transplant patients during the early pandemic with particular attention to healthcare equity. METHODS: A retrospective analysis of kidney transplant patients interacting with telemedicine was performed. Patient demographic data and distance to the transplant center were obtained. The National Center for Health Statistics (NCHS) Urban-Rural Classification Scheme for Counties and Brokamp Neighborhood Deprivation Index (NDI) score were used to characterize patients' counties of residence. Multivariable logistic regression evaluated associations between patient and community characteristics and the likelihood of an encounter being telemedicine. RESULTS: This study included 1033 patients who participated in 3727 encounters from March 11 through October 2020. Characteristics associated with decreased likelihood of telemedicine use were increased age (OR = .993; 95% CI = .986-.999, P = .022), non-White vs. White race (OR = .826, 95% CI = .697-.979; P = .028), male vs. female sex (OR = .746, 95% CI = .632-.880; P < .001), and a higher Brokamp Neighborhood Deprivation Index score (OR = .159; 95% CI = .029-.873; P = .034). The effect of distance to the transplant center on the likelihood of a telemedicine encounter differed by NCHS Urban-Rural designation (interaction P = .018), with its likelihood increasing by 2%-3% with each 10-mile increment among persons residing in medium-, small-, and non-metropolitan counties compared to those residing in the most rural counties. CONCLUSIONS: Telemedicine visits were less often completed by patients of older age, non-white race, male sex, and those residing in counties having higher NDI scores. While telemedicine has the potential to improve healthcare access and decrease costs, proactive efforts need to be taken to mitigate disparities in vulnerable populations.

Cirrhosis-related sarcopenia may not resolve after liver transplantation.

Background & Aims: Sarcopenia has significant burden in cirrhosis and has been shown to worsen short-term post-liver transplantation (LT). This study aims to evaluate the long-term change in sarcopenia post-LT along with its associations and predictors. Methods: A retrospective study of adult patients who underwent LT at a tertiary centre between 1/1/2009 and 12/31/2018. Relevant demographic and clinical data were collected. Skeletal muscle index (SMI) was calculated using standard of care computerised tomography (CT) scans pre- and post-LT. Sarcopenia was defined using previously established cut-points. The primary outcome was SMI change post-LT and secondary outcome was post-LT mortality. Results: Out of 1165 patients, 401 met inclusion criteria (1,205 CT scans reviewed). The average age at transplant was 57 years; 63% were male. The average BMI was 28 kg/m2. Thirteen percent of females and 32% of males had sarcopenia pre-LT. Post-LT SMI declined by 4.7 cm2/m2 in the first year then by 0.39 cm2/m2 per year thereafter. Females had greater rate of decline in SMI after the first year compared with males (0.87 cm2/m2 per year vs. 0.17 cm2/m2 per year, respectively, p = 0.02). Post-LT physical rehabilitation, infection, and readmissions were not associated with SMI trajectory. At 3 years post-LT, 31% of females and 48% of males had sarcopenia. Baseline sarcopenia was the only predictor of long-term post-LT sarcopenia on multivariable analysis, but it was not associated with mortality. Conclusions: Sarcopenia does not appear to resolve post-LT and likely worsens leading to nearly doubling its prevalence in those with long-term follow-up. Immediate post-LT physical rehabilitation was not associated with SMI trajectory in our cohort. Impact and implications: The prevalence of sarcopenia is high among patients with cirrhosis; however, data are mixed on the impact of sarcopenia on post-liver transplant (LT) course and there have been no studies evaluating the long-term evolution of sarcopenia post-LT beyond 1 year. In this study, we analysed changes in muscle mass up to 3 years after transplant in 401 patients and found that sarcopenia did not resolve in most liver transplant recipients and skeletal muscle mass tended to worsen after transplant with the greatest decline in muscle mass in the first year post-LT. Interestingly, sarcopenia did not influence post-transplant outcomes. Future prospective studies are needed to further understand the natural course of sarcopenia post-LT to guide interventions aiming at reversing post-LT sarcopenia.
