International Survey of Critically Ill Children With Acute Neurologic Insults: The Prevalence of Acute Critical Neurological Disease in Children: A Global Epidemiological Assessment Study*

Abstract

Objective The international scope of critical neurological insults in children is unknown. Our objective was to assess the prevalence and outcomes of children admitted to pediatric intensive care units (PICUs) with acute neurological insults. Design Prospective study. Setting Multicenter (n=107 PICUs) and multinational (23 countries, 79% in North America and Europe). Patients Children aged 7d–17y admitted to the ICU with new traumatic brain injury, stroke, cardiac arrest, central nervous system infection or inflammation, status epilepticus, spinal cord injury, hydrocephalus, or brain mass. Interventions None. Measurements and main results We evaluated the prevalence and outcomes of children with pre-determined acute neurological insults. Child and center characteristics were recorded. Unfavorable outcome was defined as change in pre-post insult Pediatric Cerebral Performance Category (PCPC) score ≥ 2 or death at hospital discharge or 3 months, whichever came first. Screening data yielded overall prevalence of 16.2%. Of 924 children with acute neurological insults, cardiac arrest (23%) and traumatic brain injury (19%) were the most common. All-cause mortality at hospital discharge was 12%. Cardiac arrest subjects had highest mortality (24%), and TBI subjects had the most unfavorable outcomes (49%). The most common neurological insult was infection/inflammation in South America, Asia, and the single African site but cardiac arrest in the remaining regions. Conclusions Neurological insults are a significant pediatric international health issue. They are frequent and contribute substantial morbidity and mortality. These data suggest a need for an increased focus on acute critical neurological diseases in infants and children including additional research, enhanced availability of clinical resources, and the development of new therapies.

The cost of a pediatric neurocritical care program for traumatic brain injury: a retrospective cohort study

“…Importantly, the PNCP supported this approach to care without requiring creation of a separate service or intensive care unit, making such approach to care easier to reproduce [ 35 ]. As the global impact of neurological diagnoses in critically ill children and the approaches to pediatric neurocritical care continue to be better defined [ 36 – 39 ] cost of implementation will become easier to assess and compare.…”

Challenges and Priorities for Pediatric Critical Care Clinician-Researchers in Low- and Middle-Income Countries

“…Mentorship should be complementary of expertise, experience, and understanding, and foster symbiotic relationships. Previous high-impact studies have proven that HIC–LMIC collaboration can successfully improve clinical care, directly benefit the participating communities and give career opportunities to local researchers ( 17 , 33 , 34 ). This should be the paradigm for PCC research study design in LMIC.…”

A study of critically ill children presenting with seizures regardless of seizure duration admitted in the PICU of a tertiary hospital in India

“…The burden of acute neurologic affliction in pediatric population is high and contributes to 16.2% of the total admissions to pediatric intensive care units (PICU) globally [ 1 ]. Status epilepticus (SE) is the commonest neuro-emergency in children and as per epidemiological studies in western countries, it's estimated incidence in children (18–20 per 100,000 children per year) is much greater than the adult incidence of around 4–6 per 100,000 per year [ [2] , [3] , [4] , [5] ].…”
