Prevalence and risk factors of post-COVID-19 condition in adults and children at 6 and 12 months after hospital discharge: a prospective, cohort study in Moscow (StopCOVID).

ABSTRACT:

Background

Previous studies assessing the prevalence of COVID-19 sequelae in adults and children were performed in the absence of an agreed definition. We investigated prevalence of post-COVID-19 condition (PCC) (WHO definition), at 6- and 12-months follow-up, amongst previously hospitalised adults and children and assessed risk factors.

Methods

Prospective cohort study of children and adults with confirmed COVID-19 in Moscow, hospitalised between April and August, 2020. Two follow-up telephone interviews, using the International Severe Acute Respiratory and Emerging Infection Consortium survey, were performed at 6 and 12 months after discharge.

Results

One thousand thirteen of 2509 (40%) of adults and 360 of 849 (42%) of children discharged participated in both the 6- and 12-month follow-ups. PCC prevalence was 50% (95% CI 47-53) in adults and 20% (95% CI 16-24) in children at 6 months, with decline to 34% (95% CI 31-37) and 11% (95% CI 8-14), respectively, at 12 months. In adults, female sex was associated with PCC at 6- and 12-month follow-up (OR 2.04, 95% CI 1.57 to 2.65) and (OR 2.04, 1.54 to 2.69), respectively. Pre-existing hypertension (OR 1.42, 1.04 to 1.94) was associated with post-COVID-19 condition at 12 months. In children, neurological comorbidities were associated with PCC both at 6 months (OR 4.38, 1.36 to 15.67) and 12 months (OR 8.96, 2.55 to 34.82) while allergic respiratory diseases were associated at 12 months (OR 2.66, 1.04 to 6.47).

Conclusions

Although prevalence of PCC declined one year after discharge, one in three adults and one in ten children experienced ongoing sequelae. In adults, females and persons with pre-existing hypertension, and in children, persons with neurological comorbidities or allergic respiratory diseases are at higher risk of PCC.

Project description:ImportanceThere is a need to understand the long-term outcomes among children infected with SARS-CoV-2.ObjectiveTo quantify the prevalence of post-COVID-19 condition (PCC) among children tested for SARS-CoV-2 infection in pediatric emergency departments (EDs).Design, setting, and participantsMulticenter, prospective cohort study at 14 Canadian tertiary pediatric EDs that are members of the Pediatric Emergency Research Canada network with 90-day, 6-month, and 12-month follow-up. Participants were children younger than 18 years who were tested for SARS-CoV-2 infection between August 2020 and February 2022. Data were analyzed from May to November 2023.ExposureThe presence of SARS-CoV-2 infection at or within 14 days of the index ED visit.Main outcomes and measuresPresence of symptoms and QoL reductions that meet the PCC definition. This includes any symptom with onset within 3 months of infection that is ongoing at the time of follow-up and affects everyday functioning. The outcome was quantified at 6 and 12 months following the index ED visit.ResultsAmong the 5147 children at 6 months (1152 with SARS-CoV-2 positive tests and 3995 with negative tests) and 5563 children at 12 months (1192 with SARS-CoV-2 positive tests and 4371 with negative tests) who had sufficient data regarding the primary outcome to enable PCC classification, the median (IQR) age was 2.0 (0.9-5.0) years, and 2956 of 5563 (53.1%) were male. At 6-month follow-up, symptoms and QoL changes consistent with the PCC definition were present in 6 of 1152 children with positive SARS-CoV-2 tests (0.52%) and 4 of 3995 children with negative SARS-CoV-2 tests (0.10%; absolute risk difference, 0.42%; 95% CI, 0.02% to 0.94%). The PCC definition was met at 12 months by 8 of 1192 children with positive SARS-CoV-2 tests (0.67%) and 7 of 4371 children with negative SARS-CoV-2 tests (0.16%; absolute risk difference, 0.51%; 95% CI, 0.06 to 1.08%). At 12 months, the median (IQR) PedsQL Generic Core Scale scores were 98.4 (90.0-100) among children with positive SARS-CoV-2 tests and 98.8 (91.7-100) among children with negative SARS-CoV-2 tests (difference, -0.3; 95% CI, -1.5 to 0.8; P = .56). Among the 8 children with SARS-CoV-2 positive tests and PCC at 12-month follow-up, children reported respiratory (7 of 8 patients [88%]), systemic (3 of 8 patients [38%]), and neurologic (1 of 8 patients [13%]) symptoms.Conclusions and relevanceIn this cohort study of children tested for SARS-CoV-2 infection in Canadian pediatric EDs, although children infected with SARS-CoV-2 reported increased chronic symptoms, few of these children developed PCC, and overall QoL did not differ from children with negative SARS-CoV-2 tests.

Project description:BackgroundPost-acute COVID-19 syndrome (PACS) is an emerging healthcare burden. The risk factors associated with PACS remain largely unclear. The aim of this study was to evaluate the frequency of new or persistent symptoms in COVID-19 patients post hospital discharge and identify associated risk factors.MethodsOur prospective cohort comprised of PCR-confirmed COVID-19 patients admitted to King Fahad Medical City, Riyadh, Saudi Arabia between May and July 2020. The patients were interviewed through phone calls by trained physicians from 6 weeks up to 6 months post hospital discharge. Multivariate Cox proportional hazards and logistic regression models were used to examine for predictors associated with persistence of symptoms and non-return to baseline health.Results222 COVID-19 patients responded to follow-up phone interviews after a median of 122 days post discharge. The majority of patients were men (77%) with mean age of 52.47 (± 13.95) years. 56.3% of patients complained of persistent symptoms; 66 (29.7%) experiencing them for >21 days and 64 (28.8%) reporting not having returned to their baseline health. Furthermore, 39 patients (17.6%) reported visiting an emergency room post discharge for COVID-19-related symptoms while 16 (7.2%) had required re-hospitalization. Shortness of breath (40.1%), cough (27.5%) and fatigue (29.7%) were the most frequently reported symptoms at follow-up. After multivariable adjustments, female gender, pre-existing hypertension and length of hospital stay were associated with an increased risk of new or persistent symptoms. Age, pre-existing lung disease and emergency room visits increased the likelihood of not fully recovering from acute COVID-19. Patients who were treated with interferon β-1b based triple antiviral therapy during hospital stay were less likely to experience new or persistent symptoms and more likely to return to their baseline health.ConclusionsCOVID-19 survivors continued to suffer from dyspnea, cough and fatigue at 4 months post hospital discharge. Several risk factors could predict which patients are more likely to experience PACS and may benefit from individualized follow-up and rehabilitation programs.

Project description:BackgroundLong-term health outcomes in children and young people (CYP) after COVID-19 infection are not well understood and studies with control groups exposed to other infections are lacking. This study aimed to investigate the incidence of post-COVID-19 condition (PCC) and incomplete recovery in CYP after hospital discharge and compare outcomes between different SARS-CoV-2 variants and non-SARS-CoV-2 infections.MethodsA prospective exposure-stratified cohort study of individuals under 18 years old in Moscow, Russia. Exposed cohorts were paediatric patients admitted with laboratory-confirmed COVID-19 infection between April 2 and December 11, 2020 (Wuhan variant cohort) and between January 12 and February 19, 2022 (Omicron variant cohort). CYP admitted with respiratory and intestinal infections, but negative lateral flow rapid diagnostic test and PCR-test results for SARS-CoV-2, between January 12 and February 19, 2022, served as unexposed reference cohort. Comparison between the 'exposed cohorts' and 'reference cohort' was conducted using 1:1 matching by age and sex. Follow-up data were collected via telephone interviews with parents, utilising the long COVID paediatric protocol and survey developed by the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC). The WHO case definition was used to categorise PCC.ResultsOf 2595 CYP with confirmed COVID-19, 1707 (65.7%) participated in follow-up interviews, with 1183/1707 (69%) included in the final 'matched' analysis. The median follow-up time post-discharge was 6.7 months. The incidence of PCC was significantly higher in the Wuhan variant cohort (89.7 cases per 1000 person-months, 95% CI 64.3-120.3) compared to post-infection sequalae in the reference cohort (12.2 cases per 1000 person-months, 95% CI 4.9-21.9), whereas the difference with the Omicron variant cohort and reference cohort was not significant. The Wuhan cohort had higher incidence rates of dermatological, fatigue, gastrointestinal, sensory, and sleep manifestations, as well as behavioural and emotional problems than the reference cohort. The only significant difference between Omicron variant cohort and reference cohort was decreased school attendance. When comparing the Wuhan and Omicron variant cohorts, higher incidence of PCC and event rates of fatigue, decreased physical activity, and deterioration of relationships was observed. The rate of incomplete recovery was also significantly higher in the Wuhan variant cohort than in both the reference and the Omicron variant cohorts.ConclusionsWuhan variant exhibited a propensity for inducing a broad spectrum of physical symptoms and emotional behavioural changes, suggesting a pronounced impact on long-term health outcomes. Conversely, the Omicron variant resulted in fewer post-infection effects no different from common seasonal viral illnesses. This may mean that the Omicron variant and subsequent variants might not lead to the same level of long-term health consequences as earlier variants.
