Abstract

Purpose:

To identify subgroups of ICU patients with high healthcare utilization for healthcare expenditure management purposes such as prevention and targeted care.

Materials and methods:

We conducted a descriptive cohort study, combining a national health insurance claims database and a national quality registry database for ICUs. Claims data in the timeframe 2012–2014 were combined with the clinical data of ICU patients admitted to an ICU during 2013. A population based control group was created based on the ICU population.

Results:

56,760 ICU patients and 75,232 controls from the general population were included. Median healthcare costs per day alive for the ICU population were significantly higher during the year before (€8.9 (IQR €2.4; €32.1)) and the year after ICU admission (€15.4 (IQR €5.4; €51.2)) compared to the control group ((€2.8 (IQR €0.7; €8.8) and €3.1 (IQR €0.8; €10.1)). ICU patients with more chronic conditions had significantly higher healthcare costs before and after ICU admission compared to ICU patients with less chronic conditions.

Conclusions:

ICU patients have three to five times higher healthcare costs per day alive compared to a control population. Our findings can be used to optimize the healthcare trajectories of ICU patients with high healthcare utilization after discharge.
