Discrepancy Between Identification of Early-Term Elective Deliveries by Manual Chart Review and Data Vendor

摘要

Elective delivery from 37 to 39 weeks gestation (early-term deliveries) is a Joint Commission National Quality Measure, and hospitals report on early-term elective delivery rates through Outcome Research Yields Excellence (ORYX) vendors. The objective of this study was to compare early-term elective deliveries, identified through ORYX vendors with those identified through manual chart review, the traditional method of medical record review. We reviewed early-term labor inductions and cesarean deliveries at a single hospital from June 1, 2010 to May 31, 2012. Rates of early-term elective deliveries identified by the data vendor were compared to physician chart review. Overall, the rate of elective deliveries by ORYX was 3% compared to 2% by physician chart review (RR 1.51 [95% CI 1.12–2.03], P < .001). Of the 116 elective early-term deliveries identified by vendor and/or chart review, vendors classified significantly more inductions and cesareans as elective (P < .001) and missed nine elective deliveries. Of the 107 deliveries identified as elective by ORYX, 62 (57.9%) were verified by chart review, including 69.0% of cesareans and 36.1% of inductions. Findings from this study suggest substantial discrepancy between identification of early-term elective deliveries by data vendors and physician chart review, and indicate that vendor-derived data may overestimate the number of electively delivered patients.
