ABSTRACT
BACKGROUND: Telemedicine has been widely used to deliver healthcare to outpatients during the COVID-19 pandemic. The effectiveness of this modality is unclear in patients with a pre-dialysis stage of chronic kidney disease (CKD). This study aims to describe the clinical characteristics and management of CKD patients receiving telemedicine care during the COVID-19 pandemic. MATERIALS AND METHODS: A retrospective single-center cohort study enrolled outpatients with pre-dialytic stage of CKD from March 9 to June 21, 2020. Telemedicine was proposed for all patients with a stable CKD to reduce the risk of in-hospital transmission whereas in-person visit was performed for patients requiring urgent evaluation. RESULTS: In a 15-week period, 97 patients received 116 nephrological visits. According to the modality of healthcare delivery, the patients were subdivided into telemedicine (66%) and in-person visit (34%) groups. Mean age of all CKD patients was 72.8 ± 12.5 years and males were 50.5% of the population. The average estimated glomerular filtration rate (eGFR) was 14.6 ± 6 mL/min. Patients evaluated by telemedicine had better kidney function (GFR, 16.2 ± 6.4 vs. 13.6 ± 5.9 mL/min/1.73m2; p = 0.037), a lower body mass index (BMI) (24.1 ± 1.7 vs. 30.6 ± 5.7; p = 0.019), and a lower risk of CKD progression (51.1 vs. 25.4%, p = 0.017) than patients requiring in-person visit. Telemedicine-visit patients experienced a significantly lower number of pharmacological changes than patients managed in the ambulatory setting. Telemedicine was also used to conduct 20% of educational meetings on the choice of dialysis modality and 18.9% of pre-eligibility visits for kidney transplantation. CONCLUSION: Telemedicine made it possible to provide care to and maintain close monitoring of 2/3 of patients with pre-dialytic stage of CKD during the COVID-19 pandemic.
ABSTRACT
The supplemented very low-protein diet (sVLPD) has proven effective in slowing the progression of stage 5 chronic renal failure and postponing the start of the dialysis treatment. However, sVLPD could expose the patient to the risk of malnutrition. This diet is also difficult to implement due to the required intake of large number of keto-analogue/amino acid tablets. In our Center, the Department of Nephrology and Dialysis of Azienda Sanitaria Territoriale n 1, Pesaro-Urbino, of Italy, respecting the guidelines of normal clinical practice, we prescribed sVLPD (0.3 g/prot/day) supplemented with only essential amino acids without the use of ketoanalogues in stage 5 patients and verified its efficacy, safety and clinical and economic effects. Over the 24 months period of observation the progression of chronic kidney disease (CKD) slowed down (mean eGFR 11.6 ± 3.3 vs. 9.3 ± 2.7 mL/min/1.73 m2, p < 0.001) and the start of the dialysis treatment (adjusted HR = 0.361, CI 0.200-0.650, p = 0.001) was delayed without evidence of malnutrition, in compliant vs. non-compliant patients. This led to a substantial cost reduction for the National Health System. This non-interventional longitudinal observational study is part of standard clinical practice and suggests that VLPD supplemented with essential amino acids could be extensively used to reduce the incidence of dialysis treatments, with a favorable economic impact on the NHS.
