Determinants of Persistence of Symptoms and Impact on Physical and Mental Wellbeing in Long COVID: A Prospective Cohort Study, 2022, Righi et al

Highlights

• Advanced age, ICU admission and multiple symptoms at onset are predictors of long COVID among patients with SARS-CoV-2 infection
• Female gender and persistence of symptoms at day 28 and month 9 were risk factors for psychological distress
• Prolonged symptoms have negative impact on both physical and mental wellbeing
• Studies on long COVID determinants and consequences are encouraged to identify target populations for recovery interventions

Abstract

Background
Residual symptoms can be detected for several months after COVID-19. To better understand the predictors and impact of symptom persistence we analysed a prospective cohort of COVID-19 patients.

Methods
Patients were followed for 9 months after COVID-19 onset. Duration and predictors of persistence of symptoms, physical health and psychological distress were assessed.

Results
465 patients (54% males, 51% hospitalised) were included; 37% presented with at least 4 symptoms and 42% complained of symptom lasting more than 28 days. At month 9, 20% of patients were still symptomatic, showing mainly fatigue (11%) and breathlessness (8%). Hospitalisation and ICU stay vs. non-hospitalised status increased the median duration of fatigue of 8 weeks. Age > 50 years (OR 2.50), ICU stay (OR 2.35), and presentation with 4 or more symptoms (OR 2.04) were independent predictors of persistence of symptoms at month 9. A total of 18% of patients did not return to optimal pre-COVID physical health, while 19% showed psychological distress at month 9. Hospital admission (OR 2.28) and persistence of symptoms at day 28 (OR 2.21) and month 9 (OR 5.16) were independent predictors of suboptimal physical health, while female gender (OR 5.27) and persistence of symptoms at day 28 (OR 2.42) and month 9 (OR 2.48) were risk factors for psychological distress.

Conclusions
Patients with advanced age, ICU stay and multiple symptoms at onset were more likely to suffer from long-term symptoms, which had a negative impact on both physical and mental wellbeing. This study contributes to identify the target populations and Long COVID consequences for planning long-term recovery interventions.

Yes, that would be the definition of symptoms. At least they got that right, though I'm not sure writing a paper about it is really necessary. Symptoms negatively impact wellbeing. Water wets things. And other basic facts of life.

 

If they only followed patients then anyone who did no show up at hospital is designed out of the study and therefore is assumed to not have LC? Am I reading this right?
