Abstract

Background: Since 1985, the Committee on Professional Liability of the American Society of Anesthesiologists has evaluated closed anesthesia malpractice claims. This study compared pediatric and adult closed claims with respect to the mechanisms of injury, outcome, the costs, and the role of care judged to be substandard.
Methods: Using a standardized form and method developed for analysis of closed claims, the American Society of Anesthesiologists Closed Claims Data Base was used to compare pediatric with adult anesthesia-related adverse events.
Results: Of the 2,400 total claims, 238 (1096) were in the pediatric age group (15 yr of age or younger). The pediatric claims presented a different distribution of damaging events compared with that of adults. In particular, respiratory events were more common among pediatric claims (43% versus 30% in adult claims; P <=. 0.01). The mortality rate was greater in the pediatric claims (50% versus35% in adult claims; P<= 0.01), anesthetic care more often was judged less than appropriate (54% versus 44% in adult claims; P <= 0.01), the complications more frequently were thought to be preventable with better monitoring (45% versus 30% in adult claims; P<= 0.01), and the distribution of payments to the plaintiff was different (median payment, $111,234 versus $90,000 in adult claims; P <= 0.05). Many of the differences between pediatric and adult claims were explained by a higher prevalence of patient injury caused by inadequate ventilation in the pediatric claims (20% versus 9% in adult claims; P <= 0.01). In pediatric compared with adult inadequate ventilation claims, poor medical condition and/ or obesity (6% versus 41%; P <= 0.01) were uncommon associated factors. Cyanosis (49%) and/or bradycardia (64%) often preceded cardiac arrest in pediatric claims related to inadequate ventilation, resulting in death (70%) or brain damage (30%) in previously healthy children. Although clinical clues suggested hypoxemia as a common mechanism of injury, the files did not contain enough information to explain the genesis of hypoxemia in these claims.
Conclusions: Comparison of adult and pediatric closed claims revealed a large prevalence of respiratory related damaging events-most frequently related to inadequate ventilation. In the opinion of the reviewers, 89% of the pediatric claims related to inadequate ventilation could have been prevented with pulse oxlmetry and/or end tidal CO2 measurement. However, pulse oximetry appeared to prevent poor outcome in only one of seven claims in which pulse oximetry was used and could possibly have done so.
