Context. Patient safety has been recognized as an important problem in health care. However, knowledge about adverse events and preventable adverse events in children is relatively limited.
Objective. To describe the incidence and types of adverse events and preventable adverse events in children.
Design. Analysis of pediatric hospitalizations in the Colorado and Utah Medical Practice Study, which involved a retrospective, 2-level (nurse and physician) medical record review of a population-based, representative sample of all pediatric hospital discharges.
Main Measures. Adverse events were defined as an injury caused by medical management rather than disease processes that resulted in either prolonged hospitalization or disability at discharge. A preventable adverse event was defined as an avoidable adverse event based on currently available knowledge and accepted practices.
Patients. 3719 discharged hospital patients, 020 years old, and 7528 nonelderly (2165 years old) discharged adult patients in Colorado and Utah.
Setting. All hospitals in Colorado and Utah.
Results. Adverse events occurred in 1% of pediatric hospitalizations in Colorado and Utah; 0.6% were preventable. Preventable adverse events rates were 0.53% in neonates and infants (00.99 years), 0.22% in children 112 years of age, and 0.95% in adolescents 1320 years of age, compared with a rate of 1.50% in nonelderly adults. Of preventable adverse event types, birth related (32.2%) and diagnostic related (30.4%) events were the most common and were significantly more common than surgically related preventable adverse events (3.5%).
Conclusions. These data suggest that
70 000 children hospitalized in the United States experience an adverse event each year; 60% of these events may be preventable. The epidemiology of adverse events and preventable adverse events in children is different than in adults. To reduce the adverse events that occur in hospitalized children, research should focus on adolescent hospitalized patients, birth-related medical care, and diagnostics in pediatric medicine.
