OBJECTIVE: The purpose of this work was to describe the frequency, characteristics, and outcomes of critical events and hospitalized children requiring medical emergency team review.
PATIENTS AND METHODS: We conducted an audit of prospectively collected medical emergency team forms and a retrospective review of medical charts during an 18-month period at a tertiary pediatric hospital in Australia. Critical events were defined as cardiac arrest, endotracheal intubation on the ward, reversal of analgesia or sedation, fluid resuscitation at >/=40 mL/kg, hyponatremia (serum sodium level of /=155 mmol/L), hypoglycemia (glucose level of
RESULTS: A total of 172 children had 225 medical emergency team calls (10.6 calls per 1000 hospital admissions and 2.0 calls per 1000 patient-days). Forty-two percent of calls were for infants <1 year old. Preexisting chronic disease was common, with 20% having a chronic underlying neurologic disorder. Forty-four percent of the children were postoperative. The mortality rate of the 172 children was 7.6% in the hospital and 13.4% within 1 year. Thirty-three children had a critical event, with reversal of analgesia being the most common event (n = 11). Postoperative children were more frequently seen in the critical-event group (64% vs 40%). Hospital and 1-year mortality rates were higher for children who had a critical event (16.1% vs 22.6%, respectively) than those who did not (5.7% vs 11.3%).
CONCLUSIONS: Chronic and complex illnesses were prevalent among children provided with urgent medical assistance from the medical emergency team in a tertiary hospital. Children in the postoperative phase were overrepresented among those with a critical event. A critical event significantly increased the risk of hospital mortality. Greater knowledge of high-risk groups is required to further improve outcomes for hospitalized children.
