To determine the extent of variability in the administration of advanced cardiac life support (ACLS) and to determine if age is associated with variability. ⋯ Wide variability exists in the administration of ACLS at the studied site. The finding that some patients receive no ACLS suggests that physicians at this site may be making bedside determinations of the likelihood of its benefit based on individual patient characteristics. The association between older age and short ACLS trials among all nonsurvivors suggests that age is most important of these characteristics.
