ABSTRACT
OBJECTIVES: To describe the characteristics of individuals receiving outpatient rehabilitation for post-acute sequelae of SARS-CoV-2 infection (PASC). Further, to examine factors associated with variation in their psychological and cognitive functioning and health-related quality of life. DESIGN: Observational study. SETTING: Outpatient COVID-19 recovery clinic at a large, tertiary, urban health system in the US. PARTICIPANTS: COVID-19 survivors with persistent sequelae (N=324). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Multivariable logistic and linear regression models were used to examine factors associated with COVID survivors' experience of severe anxiety, severe depression, post-traumatic stress disorder (PTSD), cognitive impairment, and self-reported health-related quality of life. RESULTS: About 38% of survivors seeking care for their persistent COVID symptoms suffered from severe anxiety, 31.8% from severe depression, 43% experiencing moderate to severe PTSD symptomology, and 17.5% had cognitive impairment. Their health-related quality of life was substantially lower than that of the general population (-26%) and of persons with other chronic conditions. Poor and African American/Black individuals experienced worse psychological and cognitive sequelae after COVID19 infection, even after controlling for age, sex, initial severity of the acute infection, and time since diagnosis. CONCLUSIONS: Evidence of consistent disparities in outcomes by the patients' race and socioeconomic status, even among those with access to post-acute COVID rehabilitation care, are concerning and have significant implications for PASC policy and program development.
ABSTRACT
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with significant cognitive impairment and increased risk for mental health comorbidities. This study aimed to identify specific associations between cognitive impairment, self-reported disruptions in memory, and psychiatric symptoms including depression, anxiety, posttraumatic stress disorder (PTSD), and perceived sleep concerns. Methods: Data collected from all consecutive patients with Post-Acute Sequelae of SARS-CoV-2 infection (PASC) who presented to a dedicated Post-COVID Clinic were used to evaluate whether certain psychiatric symptoms were more strongly associated with cognitive impairment and self-reported memory disturbances. Results: Univariate and multivariable analyses revealed that depression symptom severity was significantly associated with the severity of cognitive impairment among patients with PASC. This association was driven primarily by lower performance on verbal fluency, attention, and delayed recall tasks among patients with higher depression symptoms severity. Perceived sleep concerns were an important predictor of self-reported memory disturbances. Conversely, neither PTSD symptom severity nor anxiety symptom severity were significant predictors of cognitive impairment or self-reported memory disturbances. Conclusions: These findings have important clinical implications for justifying the need for screening patients with PASC for both depression and cognitive impairment.
