Study Description
The Assessment of Perinatal EXcellence (APEX) study is an observational study designed to assist in the development of quality measures for intrapartum care. The specific aim was to assess whether and to what extent hospital differences in the frequency of adverse obstetric outcomes are related to patient and hospital characteristics and to types of care provided. Data were collected on eligible patients if they delivered during the 24-hour period of selected days during a 3-year period. Days were chosen via computer-generated random selection and stratified by weekdays, weekends, and holidays. On selected days, the labor and delivery logbook at each center was screened to identify eligible women. The medical records of all eligible women and their newborns were abstracted by trained research personnel at the hospital and entered into a web-based data entry system. Maternal data were collected until discharge and neonatal data were collected until discharge or 120 days of age, whichever came first. Participants with deliveries on a pre-selected day for the admitted hospital. The delivery must occur in the hospital building (L&D, ER, ICU, or even elevator). Multifetal gestations are included. Gestational age must be 23 weeks or older.
