Additional studies were also considered from NICE surveillance up to 28 October 2020. Results from the literature searches and surveillance were screened using their titles and abstracts for relevance against the criteria from the protocol (see <a href="#niceng188er2.app2">appendix 2</a>). Four reviewers screened titles and abstracts. Having identified the evidence, four reviewers assessed the full text references of potentially relevant evidence to determine whether they met the inclusion criteria for this evidence review.

Therefore, the panel could not draw strong conclusions from the data. There was high prevalence of some symptoms reported in individual studies and some evidence of association, but most studies did not identify many confounders or adjust for any that they did find so this data is unreliable. However, the published evidence and real world evidence analysis was consistent with the patient lived experience evidence and the panel&#x02019;s own experience in terms of which symptoms were the most common amongst those people with new and ongoing symptoms after COVID-19. These symptoms, for example included fatigue and breathlessness. The patient lived experience evidence supports the panel&#x02019;s experience of people reporting many symptoms that can fluctuate and affect them differently at different times. While the panel were unable to identify an exhaustive list of symptoms, due to the uncertainty in the evidence, they were able to recommend people are made aware of what they might expect in the time following their acute illness. The panel thought that it would be helpful to have a list of the most common symptoms, so these were drawn from the studies and the patient experience. There was no evidence identified that reported outcomes on clustering of symptoms so the panel considered making a research recommendation which is outlined in the guideline.</p><p>Whilst there was some quantitative evidence on the impact of symptoms on returning to work and other activities, it was very limited, and the panel could not draw firm conclusions in order to extrapolate to the wider population from this data. The panel thought that these outcomes will be affected by individual needs and characteristics so any support or advice given should be given based on holistic approach to assessment.</p><p>The overall certainty in the evidence was low to very low. People were recruited to the studies in different ways, some of which were through self-selection and are less likely to be representative of the population. The evidence showed a consistent pattern of people who were predominantly female and most likely middle-aged and of white ethnicity. The panel did not consider the evidence to be generalisable to the whole UK population. It highlighted expected over-representation in demographics for those more likely to seek help and those who use social media. The sample sizes of the studies were also relatively small so may not be reliable to measure prevalence. Most studies did not report symptoms prior to onset of acute COVID-19 and adjust for confounders or include a control group who had not had COVID-19. The panel would have liked to have had a better understanding of symptom history prior-to COVID-19 to determine the significance of these ongoing symptoms. Only one study compared reported symptoms to a COVID-19 free control group so the panel could not be confident in the findings.</p></div><div id="niceng188er2.s5.3"><h3>Trade-off between benefits and harms</h3><p>Although the panel acknowledged that new, ongoing or recurring symptoms 12 weeks or more from acute illness onset might be more indicative of post-COVID-19 syndrome, they also thought it important to consider symptoms presenting earlier. This is to ensure symptoms that could indicate an acute complication are assessed as early as possible.</p><div id="niceng188er2.s5.3.1"><h4>Implementation and resource considerations</h4><p>Resource impact in relation to symptoms is covered in the <a href="https://www.nice.org.uk/guidance/ng188/evidence" ref="pagearea=body&amp;targetsite=external&amp;targetcat=link&amp;targettype=uri">evidence review on investigations</a>.</p></div><div id="niceng188er2.s5.3.2"><h4>Other considerations</h4><p>The panel discussed that some reported symptoms, including dizziness, light-headedness and &#x02018;brain-fog&#x02019;, were not well reported in the published quantitative literature, despite it being reported in the patient lived experience evidence and the panel seeing these commonly in practice. However, they acknowledged that people may describe these symptoms in different ways and there could be limited ways in which data is recorded in the literature.</p><p>The patient lived experience data supported the panel&#x02019;s experience of people feeling dismissed when seeking help for their symptoms, and symptoms being mis-attributed to psychological causes. The panel discussed that this could increase anxiety levels.</p><p>The panel noted that there was no evidence identified for long term effects of COVID-19 in children and older people. They discussed that older people and children may present with atypical symptoms that could be overlooked. For example, older people can present with gradual decline, deconditioning, worsening frailty or dementia and may not be eating and drinking which can have a variety of causes. It would be reasonable to consider post-COVID-19 syndrome as a cause of these symptoms.</p></div></div></div><div id="niceng188er2.app1"><h2 id="_niceng188er2_app1_">Appendix 1.
