Objective-To determine the concordance of patient recall compared to chart abstraction for distant intrapartum variables and to evaluate predictors of concordance.Methods-A random sample from a population-representative cohort of 2,109 ethnically diverse women aged 40-74 years. Intrapartum variables reported by participants were compared to data abstracted from labor and delivery records from up to 53 years prior. Outcomes were assessed for sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of patient recall compared to chart abstraction. Logistic regression was used to determine predictors of concordance of patient recall.

Recall of cesarean delivery had the highest concordance (sensitivity=0.98, specificity=1.00, PPV=1.00, NPV=0.99), followed by birth weight ≥4000gm (sensitivity=0.86, specificity=0.91, PPV=0.53, NPV=.98) Use of oxytocin and laceration requiring repair had the lowest concordance (sensitivity=0. 43, specificity=0.75, PPV=0.54, NPV=0.91; sensitivity=0.37, specificity=0.68, PPV=0.34, NPV=0.81 respectively). No variables consistently predicted concordance or discordance of recall.Conclusion-The concordance of patient recall to chart abstraction for intrapartum variables varies widely. Knowledge of the level of concordance expected for specific variables may be helpful to clinicians who often must rely on patient recall, rather then medical records, for intrapartum histories, and for researchers seeking to identify intrapartum risk factors based on patient recall.
