“…Some transcription errors are also possible with regard to the diagnoses of severe neonatal morbidity. On the other hand, previous studies [ 7 ] have shown that the database information is valid, and all diagnoses and procedures were coded using the same system (ICD-10CA and CCI) during the study period. Other study limitations include an evaluation restricted to birth weight-for-gestational age, whereas the INTERGROWTH standard (but not the Canadian reference) included other anthropometric measurements.…”

“…During the study period all diagnoses were coded using the International Classification of Diseases 10th revision, Canadian modification (ICD-10 CA), while procedures were coded using the Canadian Classification of Health Interventions (CCI). Information in the database is routinely checked for accuracy, and validation studies have shown the information to be complete and accurate [ 7 ].…”

ObjectiveTo evaluate the performance of the INTERGROWTH-21st Project newborn standard vis-a-vis the current Canadian birth weight-for-gestational age reference.MethodsAll hospital-based singleton live births in Canada (excluding Quebec) between 2002 and 2012 with a gestational age between 33 and 42 weeks were included using information obtained from the Canadian Institute for Health Information. Small- and large-for gestational age centile categories of the INTERGROWTH standard and Canadian reference were contrasted in terms of frequency distributions and rates of composite neonatal morbidity/mortality.ResultsAmong 2,753,817 singleton live births, 0.87% and 9.63% were <3rd centile and >97th centile, respectively, of the INTERGROWTH standard, while 2.27% and 3.55% were <3rd centile and >97th centile, respectively, of the Canadian reference. Infants <3rd centile and >97th centile had a composite neonatal morbidity/mortality rate of 46.4 and 12.9 per 1,000 live births, respectively, under the INTERGROWTH standard and 30.9 and 16.6 per 1,000 live births, respectively, under the Canadian reference. The INTERGROWTH standard <3rd centile and >97th centile categories had detection rates of 3.14% and 9.74%, respectively, for composite neonatal morbidity/ mortality compared with 5.48% and 4.60%, respectively for the Canadian reference. Similar patterns were evident in high- and low-risk subpopulations.ConclusionsThe centile distribution of the INTERGROWTH newborn standard is left shifted compared with the Canadian reference, and this shift alters the frequencies and neonatal morbidity/mortality rates associated with specific centile categories. Further outcome-based research is required for defining abnormal growth categories before the INTERGROWTH newborn standard can be used.

“…A validation study using 2002 data (with information from a clinically focused database in the Canadian province of Nova Scotia as the gold standard) showed high rates of accuracy for the information on PPH in the Discharge Abstract Database [ 9 ]. The sensitivity and specificity rates for PPH were 90.2% and 98.2%, respectively, while the same rates for blood transfusion were 85.7% and 99.8%, respectively.…”

BackgroundPostpartum hemorrhage (PPH) is a major cause of maternal mortality and morbidity worldwide. Several recent publications have noted an increasing trend in incidence over time. The international PPH collaboration was convened to explore the observed trends and to set out actions to address the factors identified.MethodsWe reviewed available data sources on the incidence of PPH over time in Australia, Belgium, Canada, France, the United Kingdom and the USA. Where information was available, the incidence of PPH was stratified by cause.ResultsWe observed an increasing trend in PPH, using heterogeneous definitions, in Australia, Canada, the UK and the USA. The observed increase in PPH in Australia, Canada and the USA was limited solely to immediate/atonic PPH. We noted increasing rates of severe adverse outcomes due to hemorrhage in Australia, Canada, the UK and the USA.ConclusionKey Recommendations1. Future revisions of the International Classification of Diseases should include separate codes for atonic PPH and PPH immediately following childbirth that is due to other causes. Also, additional codes are required for placenta accreta/percreta/increta.2. Definitions of PPH should be unified; further research is required to investigate how definitions are applied in practice to the coding of data.3. Additional improvement in the collection of data concerning PPH is required, specifically including a measure of severity.4. Further research is required to determine whether an increased rate of reported PPH is also observed in other countries, and to further investigate potential risk factors including increased duration of labor, obesity and changes in second and third stage management practice.5. Training should be provided to all staff involved in maternity care concerning assessment of blood loss and the monitoring of women after childbirth. This is key to reducing the severity of PPH and preventing any adverse outcomes.6. Clinicians should be more vigilant given the possibility that the frequency and severity of PPH has in fact increased. This applies particularly to small hospitals with relatively few deliveries where management protocols may not be defined adequately and drugs or equipment may not be on hand to deal with unexpected severe PPH.

Perinatal Health of Women with Intellectual and Developmental Disabilities and Comorbid Mental Illness

et al. 2016

Objective: Women with intellectual and developmental disabilities (IDD) have high rates of adverse perinatal outcomes. However, the perinatal health of women with co-occurring IDD and mental illness (dual diagnosis) is largely unknown. Our objectives were to 1) describe a cohort of women with dual diagnosis in terms of their social and health characteristics and 2) compare their risks for adverse maternal and neonatal outcomes to those of women with IDD only. Method: We conducted a population-based study using linked Ontario (Canada) health and social services administrative data to identify singleton obstetric deliveries to women with dual diagnosis (n ¼ 2080) and women with IDD only (n ¼ 1852; 2002-2012). Primary maternal outcomes were gestational diabetes, gestational hypertension, preeclampsia/eclampsia, and venous thromboembolism. Primary neonatal outcomes were preterm birth, small for gestational age, and large for gestational age. We also examined several secondary outcomes. Results: Women with dual diagnosis were more likely than women with IDD only to live in poor neighborhoods and to have prepregnancy health conditions; however, they had more frequent prenatal care. Infants born to women with dual diagnosis had increased risks for preterm birth (adjusted relative risk [aRR] 1.31, 95% confidence interval [CI] 1.08 to 1.59) and neonatal morbidity (aRR 1.35, 95% CI 1.03 to 1.76) compared with infants born to women with IDD only. All other primary and secondary outcomes were nonsignificant. Conclusions: Comorbid mental illness contributes little additional risk for adverse perinatal outcomes among women with IDD. Women with dual diagnosis and women with IDD alone require increased surveillance for maternal and neonatal complications. Abré gé Objectif : Les femmes souffrant de déficiences intellectuelles et développementales (DID) ont des taux élevés de résultats périnataux indésirables. Cependant, la santé périnatale des femmes souffrant de DID et de maladie mentale (diagnostic mixte) co-occurrentes est largement inconnue. Nos objectifs étaient de : (1) décrire une cohorte de femmes ayant un diagnostic mixte en ce qui concerne leurs caractéristiques de santé et sociales, et (2) comparer leurs risques de résultats maternels et néonataux indésirables avec ceux des femmes souffrant uniquement de DID.
