This guidance outlines British Thoracic Society (BTS) recommended follow up of patients witha clinico-radiological diagnosis of COVID-19 pneumonia. The COVID-19 swab status of patients is not relevant to this guidance. The entry point to this guidance is a clinical diagnosis of COVID-19 pneumonia with consistent radiological changes. This document may require updating as more information becomes available. This version was published on Monday 11 May2020. Please check the BTS website for the most up to date version of this document.This guidance focuses on the radiological follow up of the pneumonic process and the subsequent diagnosis and management of respiratory complications of COVID-19 pneumonia.

Data on the functional outcomes of patients surviving an intensive care unit (ICU) admission for COVID-19 is sparse. However, anecdotal experience across a number of London ICUs indicates that a high proportion has significant physical functional impairment (more than 50 % of those discharged from ICU) and the range of impairments is diverse.There is an immediate need to provide specialist, effective and targeted rehabilitation for patients recovering from the disease to improve functional outcomes and to ensure they make the best possible recovery.

The COVID-19 pandemic has led to unprecedented expansion of and challenge to our critical care services. Undoubtedly, this will require significant planning and re-structuring of dietetic services to ensure that we are able to provide a safe and effective service during this time.This document has been developed by members from the Critical Care Dietitians Specialist Group (CCSG) of the British Dietetic Association taking into account current recommendations for planning and local experiences to date. In the absence of evidence-based guidance in this area, we have drawn upon the experiences and knowledge obtained from those already working with critically ill patients with COVID-19, including our international colleagues.
