Patients With Uncomplicated Coronavirus Disease 2019 (COVID-19) Have Long-Term Persistent Symptoms and Functional Impairment Similar to Patients with Severe COVID-19: A Cautionary Tale During a Global Pandemic

Abstract: To assess the prevalence of persistent functional impairment after COVID-19, we assessed 118 individuals 3-4 months after their initial COVID-19 diagnosis with a symptom survey, work productivity and activity index questionnaire, and 6-minute walk test. We found significant persistent symptoms and functional impairment, even in non-hospitalized patients with COVID-19.

One preprint [44] was excluded because the same study has been posteriorly published in a peer-reviewed journal [30] .…”

“…Of the twenty-one studies [ 15 , 16 , 18 , [22] , [23] , [24] , [25] , 27 , 29 , [32] , [33] , [34] , [35] , [36] , [37] , [40] , [41] , [42] , [43] , 46 , 47 ] investigating the presence of post-COVID-19 symptoms in hospitalized patients, four analyzed symptoms 30 days after hospital discharge [ 15 , 33 , 41 , 43 ], nine showed a follow-up period of 60 days [ 15 , 18 , 24 , 27 , 29 , 36 , 37 , 42 , 47 ], whereas ten reported symptoms ≥90 days after discharge [ 16 , 22 , 23 , 25 , 26 , [33] , [34] , [35] , 40 , 46 ]. Overall, hospitalized COVID-19 patients were assessed a mean of 83.6±48.4 after hospital discharge.…”

“…It is still debated whether long-time persistence of symptoms in patients hospitalized for COVID-19 is pathogenically similar to that observed in ICU patients admitted for other diseases or is specifically related to SARS-CoV-2 infection. The latter hypothesis is supported by the high prevalence of persistent symptoms even in outpatients with nonsevere COVID-19 [ 24 , 25 ].…”

“…It will only be through population-based probability samples that researchers can be confident that their study populations are representative of the relevant targets. For this reason, the percentage of study participants with persistent symptoms that we and others [9,[49][50][51] calculate cannot be interpreted as meaningful population-level prevalence estimates. The threat of selection bias in the initial selection of participants also extends to our follow-up.…”
