Children aged 0-16 admitted to Swedish intensive care units and paediatric intensive care units showed low mortality rates.

Abstract

This study described the basic characteristics of children aged 0-16years who were treated in intensive care units (ICUs) and paediatric ICUs (PICUs), compared their outcomes and examined any causes of death. This was a retrospective cohort study of admissions to 74 ICUs and three PICUs in Sweden that were recorded in the Swedish Intensive Care Registry from January 1, 2008 to December 31, 2012. We retrieved data on 12756 children who were admitted 17003 times. The case mix differed between the ICUs, which were mainly admissions for injuries, accidents and observation, and PICUs, which were mainly admissions for malformations, genetic abnormalities and respiratory problems (p<0.001). The median stays in the ICUs and PICUs were 1.4 and 3.5days (p<0.001), respectively. The respective crude mortality rates were 1.1% and 2.0, and the Paediatric Index of Mortality version 2 standardised mortality ratios were 0.43 and 0.50. None of these differences were significant. Most deaths were within 24hours: About 57% in the ICUs, mainly from brain anomalies, and 13% in the PICUs, mainly from circulatory problems. Sweden had a low mortality rate in both ICUs and PICUs and the children admitted to these two types of unit differed.
