Insights

Children treated in Pediatric Intensive Care Units (PICUs) had lower mortality rates compared to those in adult ICUs. Factors like mechanical ventilation and emergency admission increased mortality risk in pediatric intensive care.

Area of Science:

  • Pediatric critical care medicine
  • Intensive care unit outcomes
  • Epidemiology of pediatric critical illness

Background:

  • The optimal setting for pediatric intensive care remains a subject of investigation.
  • Understanding variations in mortality risk based on the type of intensive care unit (ICU) is crucial for improving outcomes in critically ill children.
  • Previous studies have suggested potential differences in care and outcomes between pediatric and adult ICUs.

Purpose of the Study:

  • To compare mortality rates between children treated in Pediatric Intensive Care Units (PICUs) and adult Intensive Care Units (ICUs).
  • To identify factors associated with increased mortality risk in pediatric patients admitted to ICUs.
  • To analyze the impact of ICU type (PICU vs. adult university hospital ICU vs. adult central hospital ICU) on pediatric patient outcomes.

Main Methods:

  • A national multicenter cohort study was conducted in Finland.
  • Data from 30 ICUs (26 national registries and 3 electronic management systems) were analyzed.
  • Study included 4,876 children younger than 17 years, assessing admissions, length of stay, diagnoses, and mortality.

Main Results:

  • Overall survival to discharge was high at 98.9%.
  • Mechanical ventilation was required by 35% of patients in PICUs and adult university hospital ICUs, versus 19% in central hospital ICUs.
  • Treatment in adult ICUs (both university and central hospitals) was associated with significantly higher odds of mortality compared to PICUs, even after adjustment for key variables.

Conclusions:

  • Pediatric patients treated in dedicated PICUs experienced lower mortality rates.
  • Mechanical ventilation, emergency admission, and readmission within 48 hours were linked to increased mortality risk.
  • Specific diagnoses including cardiovascular, gastrointestinal, acute infections, hematologic/oncologic diseases, and nonsurgical trauma were also associated with higher mortality.
