Remote digital urinalysis with smartphone technology as part of remote management of glomerular disease during the SARS-CoV-2 virus pandemic: single-centre experience in 25 patients

Abstract

ABSTRACT Background The COVID-19 pandemic has necessitated the provision of healthcare through remote and increasingly digitalized means. The management of glomerular pathology, for which urinalysis is crucial, has been notably affected. Here we describe our single-centre experience of using remote digital urinalysis in the management of patients with glomerular disease during the COVID-19 pandemic. Method All patients with native kidney glomerular disease who consented to participate in digital smartphone urinalysis monitoring between March 2020 and July 2021 were included. Electronic health records were contemporaneously reviewed for outcome data. Patient feedback was obtained through the testing portal. Results Twenty-five patients utilized the digital urinalysis application. A total of 105 digital urinalysis tests were performed for a wide variety of indications. Four patients experienced a relapse (detected remotely) and two patients underwent three successful pregnancies. The majority of patients were managed virtually (60%) or virtually and face to face (F2F) combined (32%). The average number of clinic reviews and urine tests performed during the pandemic either virtually and/or F2F was comparable to levels pre-pandemic and the ratio of reviews to urinalysis (R:U) was stable (pre-pandemic 1:0.9 versus during the pandemic 1:0.8). Patients seen exclusively F2F with supplementary home monitoring had the highest R:U ratio at 1:2.1. A total of 95% of users provided feedback, all positive. Conclusion Remote urinalysis proved a safe and convenient tool to facilitate decision-making where traditional urinalysis was difficult, impractical or impossible. Our approach allowed us to continue care in this vulnerable group of patients despite a lack of access to traditional urinalysis.
