Objectives: To
describe the types and prevalence of chronic conditions in an ICU population
and a population-based control group during the year before ICU admission and
to quantify the risk of developing new chronic conditions in ICU patients
compared with the control group.
Design: We
conducted a retrospective cohort study, combining a national health insurance
claims database and a national quality registry for ICUs. Claims data in the
timeframe 2012–2014 were combined with clinical data of patients who had been
admitted to an ICU during 2013. To assess the differences in risk of developing
new chronic conditions, ICU patients were compared with a population-based
control group using logistic regression modeling.
Setting:
Eighty-one Dutch ICUs.
Patients: All
patients admitted to an ICU during 2013. A population-based control group was
created, and weighted on the age, gender, and socio-economic status of the ICU
population. Interventions: None.
Measurements and Main Results: ICU patients (n = 56,760) have more chronic
conditions compared with the control group (n = 75,232) during the year before
ICU admission (p < 0.0001). After case-mix adjustment ICU patients had a
higher risk of developing chronic conditions, with odds ratios ranging from
1.67 (CI, 1.29–2.17) for asthma to 24.35 (CI, 14.00–42.34) for epilepsy,
compared with the control group.
Conclusions: Due
to the high prevalence of chronic conditions and the increased risk of
developing new chronic conditions, ICU follow-up care is advised and may focus
on the identification and treatment of the new developed chronic conditions.
