Time from pre‐labor rupture of membrane at term to delivery in grand multiparous women

Key Points

To investigate the differences in delivery timing after pre-labor rupture of membranes in grand multiparous women.
Analyzed labor duration in grand multiparous women after term PROM.
Assessed subgroup variations in delivery timing.
Utilized percentile-based assessment for the timing of intervention.
Identified clinically relevant heterogeneity in labor progression post-PROM.
Discovered a distinct subgroup with delayed delivery not reflected in average estimates.

Abstract

Beyond confirming known parity-related differences in labor duration after term PROM, this study demonstrates clinically relevant heterogeneity within the grand multiparous population. A distinct subgroup shows delayed progression that is not captured by mean or median estimates. Distributional, percentile-based assessment may refine counseling and support more individualized timing of intervention following term PROM.
