Long-term patient symptoms and quality of life in adults after COVID-19: a real life study

Abstract

Objective: To characterize long-term patient-reported symptoms and quality of life, in adults after COVID-19. Material and methods: Cross-sectional study in Cantabria (Northern Spain) including adults with PCR-confirmed SARS-CoV-2 infection (n = 694) with a time period between 4.7 and 24 month post-SARS-CoV-2 diagnosis, and their close contacts (n = 663) (PCR negative and without suspected infection) obtained from simple random sampling of a total of 47,773 cases and 94,301 close contacts. The ISARIC survey was used as screening tool with self-reported "non-feeling fully recovery (NFFR)" defined as primary outcome. Results: 16.57% (n = 115/694) reported NFFR. Most prevalent symptoms were in order of frequency: Fatigue (54.8%); Loss of smell (40.9%); Problems speaking or communicating (29.6%); Loss of taste (28.7%); Confusion/lack of concentration (27.8%); Persistent muscle pain (24.3%) and Shortness of breath/breathlessness (23.5%). When comparing the three ordinal groups (Close contacts, COVID-19 feeling recovered, and COVID-19 NFFR) the prevalence of these symptoms was increasingly higher among each ordinal group (p < 0.001). Female gender was significantly associated with NFFR: (adjusted odds ratio (aOR) = 1.56); as well as older age: aOR per 10 year increment = 1.15. Lastly, they scored on average 9.63 points less in Euroquol. Conclusions: More than 15% of patients in our real-life population-based study, reported NFFR, being female sex and older age independent predictors of this condition. Most symptoms in these patients were in accordance with WHO definition of post COVID-19 condition in adults, and were less prevalent in COVID-19 feeling recovered and close contact respectively, with a statistically significant dose-response pattern, and with a large decrease in quality of life according to Euroquol.
