The NSW Midwives Data Collection 1990

Abstract

The proportion of births following an induced labour was lower in January-June 1990 (17.9 per cent) than 1987 (20.1 per cent). However, as Table 1 shows, the reported incidence of augmentation increased (23.4 per cent in 1990. compared with 17.4 per cent in 1987).

Rates for obstetric intervention among private and public patients in Australia: population based descriptive study

“…Data were obtained from the NSW Midwives Data Collection, a population based surveillance system covering all births in New South Wales, which relies on midwives to record information on each birth. 8 9 We compared maternal demographic and clinical factors among public and private patients. Maternal factors available for analysis were age, parity, medical conditions (any or none reported, including pre-existing diabetes mellitus and essential hypertension), and obstetric complications (any or none reported, including antepartum haemorrhage, pregnancy induced hypertension, gestational diabetes, and rupture of membranes before labour).…”

Trends in postpartum haemorrhage

“…10 (This is consistent with a 1990 validation of population birth data (sensitivity 66%)). 12 Although the administrative coding system used by hospitals was updated to ICD-10 in July 1998, the defi nition of PPH did not alter and a trend of increasing PPH during the birth admission was evident prior to the introduction of ICD-10. The introduction of the new policy framework and focus on PPH may increase PPH reporting even if practices to reduce PPH are more rigorously instituted.…”

Quality of Data in Perinatal Population Health Databases

“…Reporting of neonatal deaths in perinatal death certificates was examined in 1 study 33 and reporting of maternal conditions on the fetal death certificate by another study. 41 Reporting of maternal or infant conditions and procedures in a general population of pregnant women were reported in 31 of the 43 included studies, [20][21][22][23][25][26][27][28]31,32,[34][35][36][37][38][39][40][42][43][44][45][46][47][49][50][51][52][53]55,56,59 20 of these studies included over 1000 participants sampled from more than 1 hospital. The accuracy of reporting of some conditions were limited to pregnant women with those conditions (uterine rupture, 24 preeclampsia or eclampsia, 30,48 diabetes, 54 and venous thrombosis 58 ), whereas 1 study examined a range of maternal and infant conditions in a population of pregnant women with asthma.…”

“…29 The gold standard used in most studies was from data abstracted from medical records, including abstracted data on preexisting medical conditions 23,32,50 and from prenatal records when available. 39,40,52,59 Of those studies that used medical records as the gold standard, we could ascertain that 7 were audit studies, 21,45,46,52,53,55,59 whereas 16 were classified as validation studies. [23][24][25]27,31,32,36,37,39,40,43,47,[49][50][51]53 Other gold standards used to assess reporting in hospital and birth records include specialized databases, 26,28,29,34,42,44,54 physical examination, or ultrasound results 44 and 2 studies used guidelines from American College of Obstetrics and Gynecology (ACOG) to ascertain the diagnosis of preeclampsia and eclampsia.…”
