Objective To assess the impact of publicly reporting a statewide fetal growth restriction (FGR) performance indicator. Design Retrospective cohort study from 2000 to 2017. Setting All maternity services in Victoria, Australia. Population A total of 1 231 415 singleton births at ≥32 weeks of gestation. Methods We performed an interrupted time‐series analysis to assess the impact of publicly reporting an FGR performance indicator on the rate of detection for severe cases of small for gestational age (SGA). Rates of perinatal mortality and morbidity and obstetric intervention were assessed for severe SGA pregnancies and pregnancies delivered for suspected SGA. Main outcome measures Gestation at delivery, obstetric management and perinatal outcome. Results The public reporting of a statewide FGR performance indicator was associated with a steeper reduction per quarter in the percentage of severe SGA undelivered by 40 weeks of gestation, from 0.13 to 0.51% (P = 0.001), and a decrease in the stillbirth rate by 3.3 per 1000 births among those babies (P = 0.01). Of babies delivered for suspected SGA, the percentage with birthweights ≥ 10th centile increased from 41.4% (n = 307) in 2000 to 53.3% (n = 1597) in 2017 (P < 0.001). Admissions to a neonatal intensive care unit for babies delivered for suspected SGA but with a birthweight ≥ 10th centile increased from 0.8 to 2.0% (P < 0.001). Conclusions The public reporting of an FGR performance indicator has been associated with the improved detection of severe SGA and a decrease in the rate of stillbirth among those babies, but with an increase in the rate of iatrogenic birth for babies with normal growth. Tweetable abstract The public reporting of hospital performance is associated with a reduction in stillbirth, but also with unintended interventions.

“…The major strength of this study is the population‐based design using data from a validated collection recorded prospectively by caregivers. The inclusion of all births in the state ensures that it is representative, eliminating the possibility of sampling bias.…”

“…De‐identified data were obtained from the VPDC, a recently validated statutory collection of prospectively collected perinatal data for all births occurring in Victoria. A standardised set of information comprising demographic and clinical information on many aspects of prenatal, intrapartum and postpartum procedures and outcomes for the mother and baby is submitted at the completion of the birth event, usually by midwives.…”

“…We analysed data from the Victorian Perinatal Data Collection (VPDC), a population surveillance system that captures information on obstetric conditions, procedures, pregnancy, and birth outcomes (live and stillbirths) registered under the Victorian Birth, Deaths and Marriages Registration Act 1996. 10,11 To examine variations in vaccination uptake by time of year, we analysed data for all pregnancies captured by the VPDC that ended during 1 July 2015 -30 June 2017. Data were aggregated by the month and year the pregnancy ended, hospital of birth, and maternal vaccination status.…”

Objectives To assess variations by time of year and hospital in the uptake of influenza and pertussis vaccinations by pregnant women in Victoria; to identify factors associated with vaccination uptake. Design, setting Retrospective analysis of data in the Victorian Perinatal Data Collection (VPDC), a population surveillance system for obstetric conditions, procedures, and pregnancy and birth outcomes. Participants Women whose pregnancies ended in a live or stillbirth during July 2015 – June 2017. Main outcome measures Influenza and pertussis vaccinations during pregnancy. Results 153 980 pregnancies in 67 hospitals ended during July 2015 – June 2017; 59 968 pregnant women (39.0%) were vaccinated against influenza and 98 583 (64.0%) against pertussis. Coverage varied by pregnancy end date, rising for influenza during winter and spring, but for pertussis rising continuously across the two years from 37.5% to 82.2%. Differences between hospitals in coverage were marked. Factors associated with vaccination included greater maternal age, primigravidity, early antenatal care, and GP‐led care. The odds of vaccination were statistically significantly lower for women born overseas and those who smoked during pregnancy; the odds of vaccination were also lower for Aboriginal and Torres Strait Islander women. Conclusions Pertussis vaccination of pregnant women in Victoria has increased, but influenza vaccination rates remain moderate and variable. Structural changes at the system level may improve maternal vaccination rates. Embedding the delivery of maternal vaccination programs in antenatal care pathways should be a priority.

Data accuracy in the Victorian Perinatal Data Collection: Results of a validation study of 2011 data

Abstract: This study found high levels of accuracy for data reported to the VPDC for births in 2011; however, some data items introduced in 2009 and not previously validated were less accurate. Data may be used with confidence overall and with awareness of limitations for some new items.
