Effective Jan. 1, The Joint Commission will require accredited hospitals with at least 300 live births per year to report the percentage of infants with unexpected newborn complications among full-term newborns with no pre-existing conditions, the organization announced yesterday. All hospitals seeking perinatal care certification also will be required to report on the measure. A Joint Commission working group also is considering whether to establish possible requirements for hospitals to standardize management of patients with hemorrhage or hypertension, the organization said.
