Abstract

Purpose: The association between severity of illness and ability to return to work is unclear. Therefore, we investigated return to work and associations with measures of illness severity in ICU survivors.

Methods: We conducted this cohort study using Danish registry data for the period 2005-2014 on ICU patients who were discharged alive from hospital, had an ICU length of stay (LOS) of at least 72 h, were not treated with dialysis before hospital admission and were working prior to admission. We assessed (1) the cumulative incidence (chance) of return to work (2005-2017) and receipt of social benefits after discharge from a hospital stay with ICU admission and (2) the association between organ support therapies (renal replacement therapy, cardiovascular support and mechanical ventilation), and during 2011-2014 SAPS II and ICU LOS, and return to work, using multivariable Cox regression.

Results: Among 5762 ICU survivors, 68% returned to work within 2 years after hospital discharge. Disability and sickness benefits constituted 89% of social benefits among patients not returning to work and 59% among patients withdrawing from work following an initial return to work. Mechanical ventilation (HR 0.70, 95% CI [0.65-0.77]), but not RRT (HR 0.85, 95% CI [0.71-1.02]), cardiovascular support (HR 0.93, 95% CI [0.82-1.07]) and increasing SAPS II, was associated with decreased chance of return to work. Increasing ICU LOS was also associated with a decreased chance of return to work.

Conclusions: The majority of a nationwide cohort of ICU survivors returned to work. Sick leave and receipt of disability pension were common following ICU admission. Mechanical ventilation and longer ICU LOS were associated with reduced chances of return to work.
