ABSTRACT
In Situation Report #13 and 39 days before declaring COVID-19 a pandemic, the WHO declared a COVID-19 infodemic. The volume of coronavirus tweets was far too great for one to find accurate or reliable information. Healthcare workers were flooded with noise which drowned the signal of valuable COVID-19 information. To combat the infodemic, physicians created healthcare-specific micro-communities to share scientific information with other providers. We analyzed the content of eight physician-created communities and categorized each message in one of five domains. We coded 1) an application programming interface to download tweets and their metadata in JavaScript Object Notation and 2) a reading algorithm using visual basic application in Excel to categorize the content. We superimposed the publication date of each tweet into a timeline of key pandemic events. Finally, we created NephTwitterArchive.com to help healthcare workers find COVID-19-related signal tweets when treating patients. We collected 21071 tweets from the eight hashtags studied. Only 9051 tweets were considered signal: tweets categorized into both a domain and subdomain. There was a trend towards fewer signal tweets as the pandemic progressed, with a daily median of 22% (IQR 0-42%). The most popular subdomain in Prevention was PPE (2448 signal tweets). In Therapeutics, Hydroxychloroquine/chloroquine wwo Azithromycin and Mechanical Ventilation were the most popular subdomains. During the active Infodemic phase (Days 0 to 49), a total of 2021 searches were completed in NephTwitterArchive.com, which was a 26% increase from the same time period before the pandemic was declared (Days -50 to -1). The COVID-19 Infodemic indicates that future endeavors must be undertaken to eliminate noise and elevate signal in all aspects of scientific discourse on Twitter. In the absence of any algorithm-based strategy, healthcare providers will be left with the nearly impossible task of manually finding high-quality tweets from amongst a tidal wave of noise.

COVID-19ABSTRACT
The COVID-19 pandemic has disrupted health care delivery globally. Patients on in-centre haemodialysis(HD) are particularly affected due to their multiple hospital visits and the need for uninterrupted care for their well-being and survival. We studied the impact of the pandemic and the national policy for pandemic control on the HD care delivery in Karnataka state in India in April 2020, when the first and second national lockdown were in place. An online, questionnaire based survey of dialysis facilities was conducted and the responses analysed. The questions were pertaining to the key areas such as changes in number of dialysis treatments, frequency, duration, expenses, transportation to and from dialysis units, impact on availability of consumables, effect on dialysis personnel and on machine maintenance. 62 centres participated. Median of dialysis treatments for the months of March and April 2020 were 695.5 and 650 respectively. Reduction in dialysis treatments was noted in 29(46.8%) facilities , decreased frequency reported by 60 centres. In at least 35(56.5%) centres, dialysis patients had to bear increased expenses. Cost and availability of dialysis consumables were affected in 40(64.5%) and 55(88.7%) centres respectively. Problems with transportation and movement restriction were the two key factors affecting both patients and dialysis facilities.This survey documents the collateral impact of COVID -19 on the vulnerable group of patients on HD, even when not affected by COVID. It identifies the key areas of challenges faced by the patients and the facilities and implores the care-providers for finding newer avenues for mitigation of the problems.
