The standardization of medical practice is gaining acceptance as a tec
hnique for controlling length of stay and hospital charges, while main
taining quality. Most clinical pathways address specific diagnoses or
procedures, but we have developed a new approach in which pathways for
cardiac care are based on acuity. All congenital cardiac surgical car
e rendered at Columbus Children's Hospital now falls within one of fou
r such clinical pathways. This simplified approach is easy to use and
has been well accepted. Our experience in a group of 107 consecutive p
atients treated in this fashion is described. The results of variance
analyses, along with length of stay and charge data, are presented to
demonstrate the degree to which resource utilization can be standardiz
ed in this widely variable group of patients whose problems were made
cohesive by classification according to acuity level. We conclude that
the resultant standardization offers considerable advantages for the
managed care environment.
