Prior to 2009 PPH<\/jats:styled-content> was collected via a tick box item on the perinatal form. Estimated blood loss (EBL<\/jats:styled-content>) volume is now collected and it is from this item the PPH<\/jats:styled-content> rate is calculated. Periodic assessment of data accuracy is essential to inform clinicians and others who rely on these data of their quality and limitations.<\/jats:p><\/jats:sec>Aims<\/jats:title>This paper describes the results of a state\u2010wide validation study of the accuracy of EBL<\/jats:styled-content> volume and EBL<\/jats:styled-content>\u2010related data items reported to VPDC<\/jats:styled-content>.<\/jats:p><\/jats:sec>Materials and methods<\/jats:title>PPH<\/jats:styled-content> data from a random sample of 1% of births in Victoria in 2011 were extracted from source medical records and compared with information submitted to the VPDC<\/jats:styled-content>. Accuracy was determined, together with sensitivity, specificity, positive predictive value and negative predictive value for dichotomous items.<\/jats:p><\/jats:sec>Results<\/jats:title>Accuracy of reporting for EBL \u2265\u00a0500\u00a0mL was 97.2% and for EBL \u2265\u00a01500\u00a0mL was 99.7%. Sensitivity for EBL \u2265\u00a0500\u00a0mL was 89.0% (CI<\/jats:styled-content> 83.1\u201093.0) and for EBL\u00a0\u2265\u00a01500\u00a0mL was 71.4% (CI<\/jats:styled-content> 35.9\u201391.8). Blood product transfusion, peripartum hysterectomy and procedures to control bleeding were all accurately reported in >99% of cases.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Most PPH<\/jats:styled-content>\u2010related data items in the 2011 VPDC<\/jats:styled-content> may be considered reliable. Our results suggest EBL\u00a0\u2265\u00a01500\u00a0mL is likely to be under\u2010reported.
