Recovery from Covid-19 critical illness: A secondary analysis of the ISARIC4C CCP-UK cohort study and the RECOVER trial

Fatigue outcomes following COVID-19: a systematic review and meta-analysis

OBJECTIVES

Fatigue is a pervasive clinical symptom in coronaviruses and may continue beyond the acute phase, lasting for several months or years. This systematic review and meta-analysis aimed to incorporate the current evidence for postinfection fatigue among survivors of SARS-CoV-2 and investigate associated factors.

METHODS

Embase, PsyINFO, Medline, CINAHL, CDSR, Open Grey, BioRxiv and MedRxiv were systematically searched from January 2019 to December 2021. Eligible records included all study designs in English. Outcomes were fatigue or vitality in adults with a confirmed diagnosis of SARS-CoV-2 measured at >30 days post infection. Non-confirmed cases were excluded. JBI risk of bias was assessed by three reviewers. Random effects model was used for the pooled proportion with 95% CIs. A mixed effects meta-regression of 35 prospective articles calculated change in fatigue overtime. Subgroup analyses explored specific group characteristics of study methodology. Heterogeneity was assessed using Cochran's Q and I2 statistic. Egger's tests for publication bias.

RESULTS

Database searches returned 14 262 records. Following deduplication and screening, 178 records were identified. 147 (n=48 466 participants) were included for the meta-analyses. Pooled prevalence was 41% (95% CI: 37% to 45%, k=147, I2=98%). Fatigue significantly reduced over time (-0.057, 95% CI: -107 to -0.008, k=35, I2=99.3%, p=0.05). A higher proportion of fatigue was found in studies using a valid scale (51%, 95% CI: 43% to 58%, k=36, I2=96.2%, p=0.004). No significant difference was found for fatigue by study design (p=0.272). Egger's test indicated publication bias for all analyses except valid scales. Quality assessments indicated 4% at low risk of bias, 78% at moderate risk and 18% at high risk. Frequently reported associations were female gender, age, physical functioning, breathlessness and psychological distress.

CONCLUSION

This study revealed that a significant proportion of survivors experienced fatigue following SARS-CoV-2 and their fatigue reduced overtime. Non-modifiable factors and psychological morbidity may contribute to ongoing fatigue and impede recovery.

Patients' perspectives of recovery after COVID-19 critical illness: An interview study

BACKGROUND

Critical illness is a traumatic experience, often resulting in post-intensive care syndrome, affecting people's physical, psychological, emotional, and social well-being. The early recovery period is associated with increased risk, negatively impacting longer-term outcomes.

AIMS

The aims of this study were to understand the recovery and rehabilitation needs of people who survive a COVID-19 critical illness.

DESIGN AND METHODS

An exploratory descriptive qualitative interview study with 20 survivors of COVID-19 critical illness from two community-based healthcare settings in London, England. Data collection took place September 2020-April 2021, at least 1 month after hospital discharge by telephone or virtual platform. Data were subjected to inductive thematic analysis and mapped deductively to the three core concepts of self-determination theory: autonomy, competence and relatedness.

FINDINGS

Three key themes emerged: traumatic experience, human connection and navigating a complex system. Participants described how societal restrictions, fear and communication problems caused by the pandemic added to their trauma and the challenge of recovery. The importance of positive human connections, timely information and support to navigate the system was emphasized.

CONCLUSIONS

Whilst findings to some extent mirror those of other qualitative pre-pandemic studies, our findings highlight how the uncertainty and instability caused by the pandemic add to the challenge of recovery affecting all core concepts of self-determination (autonomy, competence, relatedness).

RELEVANCE TO CLINICAL PRACTICE

Understanding survivors' perspectives of rehabilitation needs following COVID-19 critical illness is vital to delivery of safe, high-quality care. To optimize chances of effective recovery, survivors desire a specialist, co-ordinated and personalized recovery pathway, which reflects humanized care. This should be considered when planning future service provisions.
