Insights
Pediatric abdominal compartment syndrome (ACS) incidence and mortality remained stable from 2007-2019. Mortality was highest in neonates, and wide hospital variations suggest potential diagnostic inconsistencies in pediatric ACS care.
Area of Science:
- Pediatric critical care medicine
- Surgical critical care
- Pediatric hospital epidemiology
Background:
- Abdominal compartment syndrome (ACS) is a critical condition characterized by elevated intra-abdominal pressure leading to multiorgan dysfunction.
- Pediatric ACS is associated with high mortality, but national incidence and mortality rates are not well-established.
- Understanding these rates is crucial for improving care and outcomes in children.
Purpose of the Study:
- To determine the national incidence and mortality rates of pediatric ACS.
- To analyze trends in pediatric ACS incidence and mortality over a 13-year period (2007-2019).
- To investigate variations in incidence and mortality across different age groups and hospitals in the United States.
Main Methods:
- Retrospective cohort study utilizing the Pediatric Health Information Systems database (2007-2019).
- Identification of pediatric patients (<18 years) with ACS using ICD-9 and ICD-10 codes.
- Analysis of primary outcomes (incidence and mortality) by year, age, and hospital of admission.
Main Results:
- A total of 2887 pediatric ACS cases were identified across 49 children's hospitals.
- The overall incidence of pediatric ACS was 0.17%, with an overall mortality of 48.87%.
- Mortality was significantly higher in neonates (0-30 days old) at 58.61% compared to older children. Annual incidence and mortality showed no significant change over the study period. Wide variations in hospital-specific incidence (0.04%-0.46%) and mortality (28.57%-71.43%) were observed.
Conclusions:
- Pediatric ACS incidence and mortality rates have remained consistent between 2007 and 2019.
- ACS continues to be a high-mortality condition in children, particularly neonates.
- Significant inter-hospital variability in ACS incidence and mortality suggests potential disparities in recognition and diagnosis, highlighting a need for standardized care protocols.
Introduction:
Abdominal compartment syndrome (ACS) is the presence of intra-abdominal hypertension with systemic, multiorgan effects and is associated with high mortality, yet the national incidence and mortality rates of pediatric ACS remain unknown. The aim of this study is to evaluate the incidence and mortality of pediatric ACS over a 13-year period across multiple children's hospitals and between individual children's hospitals in the United States.
Methods:
We performed a retrospective cohort study on children (aged < 18 y) with ACS in the Pediatric Health Information Systems database from 2007 to 2019. We identified ACS patients by International Classification of Diseases codes in the ninth and 10th revision. The primary outcomes were incidence and mortality, which were analyzed by year, age, and hospital of admission.
Results:
Across 49 children's hospitals, we identified 2887 children with ACS from 2007 to 2019 in the Pediatric Health Information Systems database. The overall incidence of ACS was 0.17% and the overall mortality was 48.87%. There was no significant difference in annual incidence (P = 0.12) or mortality (P = 0.39) over the study period. There was no difference in incidence across age group (P = 0.38); however, mortality in patients 0-30 d old (58.61%) was significantly higher than older age groups (P < 0.0001). The hospital-specific incidence (0.04%-0.46%) and mortality (28.57%-71.43%) varied widely.
Conclusions:
The annual incidence and mortality of pediatric ACS are unchanged from 2007 to 2019. ACS mortality remains high, especially in neonatal intensive care unit patients. No obvious correlation is seen between incidence rates and mortality. Differing hospital-specific incidence and mortality could suggest inconsistencies between institutions that affect pediatric ACS care, perhaps with respect to recognition and diagnosis.
