Return to work after critical illness: a systematic review and meta-analysis

Abstract

BackgroundSurvivors of critical illness often experience poor outcomes after hospitalisation, including delayed return to work, which carries substantial economic consequences.ObjectiveTo conduct a systematic review and meta-analysis of return to work after critical illness.MethodsWe searched PubMed, Embase, PsycINFO, CINAHL and Cochrane Library from 1970 to February 2018. Data were extracted, in duplicate, and random-effects meta-regression used to obtain pooled estimates.ResultsFifty-two studies evaluated return to work in 10 015 previously employed survivors of critical illness, over a median (IQR) follow-up of 12 (6.25–38.5) months. By 1–3, 12 and 42–60 months’ follow-up, pooled return to work prevalence (95% CI) was 36% (23% to 49%), 60% (50% to 69%) and 68% (51% to 85%), respectively (τ2=0.55, I2=87%, p=0.03). No significant difference was observed based on diagnosis (acute respiratory distress syndrome (ARDS) vs non-ARDS) or region (Europe vs North America vs Australia/New Zealand), but was observed when comparing mode of employment evaluation (in-person vs telephone vs mail). Following return to work, 20%–36% of survivors experienced job loss, 17%–66% occupation change and 5%–84% worsening employment status (eg, fewer work hours). Potential risk factors for delayed return to work include pre-existing comorbidities and post-hospital impairments (eg, mental health).ConclusionApproximately two-thirds, two-fifths and one-third of previously employed intensive care unit survivors are jobless up to 3, 12 and 60 months following hospital discharge. Survivors returning to work often experience job loss, occupation change or worse employment status. Interventions should be designed and evaluated to reduce the burden of this common and important problem for survivors of critical illness.Trial registration numberPROSPERO CRD42018093135.

Survivorship after COVID-19 ICU stay

“…The interplay of physical, cognitive and mental health impairments can lead to important functional problems, such as persistent fatigue, chronic pain and sleep dysfunction, and reduced health-related quality of life 8 . Moreover, globally, at 1-year follow-up, one-third of previously employed survivors of ICU stay are jobless 9 . The financial burden of job loss is worsened by direct or indirect health-care costs and lost income of patients' caregivers.…”

“…ICU survivors, especially those who are mechanically ventilated, often suffer from impairments in physical function, cognitive function, swallowing, and/ or emotional health collectively known as post-intensive care syndrome (PICS) [59]. These deficits may persist for months or years after a critical illness, and have substantial impact on quality of life, return to work, and disability in activities of daily living [60]. Neurologic symptoms manifest in a notable proportion of patients with COVID-19 [7].…”
