Examining Cesarean Section Rates in Canada Using the Modified Robson Classification.

OBJECTIVE: Canada's cesarean delivery (CD) rate continues to increase. The Society of Obstetricians and Gynaecologists of Canada advocates the use of the modified Robson classification for comparisons. This study describes national and provincial CD rates according to this classification system. METHODS: All 2016-2017 in-hospital births in Canada (outside Québec) reported to the Discharge Abstract Database were categorized using the modified Robson classification system. CD rates, group size, and contributions of each group to the overall volume of CD were reported. Rates by province and hospital peer group were also examined (Canadian Task Force Classification III). RESULTS: A total of 286 201 women gave birth; among these, 83 262 (29.1%) had CDs. Robson group 5 (term singleton previous CD) had a CD rate of 80.5% and was the largest contributing group to the overall number of CD (36.6%). Women whose labour was induced (Robson group 2A) had a CD rate almost double the rate of women with spontaneous labour (Robson group 1): 33.5% versus 18.4%. These latter two groups made the next largest contributions to overall CD (15.7% and 14.1%, respectively). There were substantial variations in CD rates across provinces and among hospital peer groups. CONCLUSION: The study found large variations in CD rates across provinces and hospitals within each Robson group, thus suggesting that examining variations to determine the groups contributing the most to CD rates (Robson groups 5, 2A, and 1) may provide valuable insight for reducing CD rates. This study provides a benchmark for measuring the impact of future initiatives to reduce CD rates in Canada.

Management of Spontaneous Labour at Term in Healthy Women.

OBJECTIVE: The purpose of this guideline is to provide guidance for the intrapartum management of spontaneous labour, whether normal or abnormal, in term, healthy women, and to provide guidance in the management of first and second stage dystocia to increase the likelihood of a vaginal birth and optimize birth outcomes. EVIDENCE: Published literature was retrieved through searches of PubMed and the Cochrane Library in October 2011 using appropriate, controlled vocabulary (e.g., labour pain; labour, obstetric; dystocia) and key words (e.g., obstetric labor, perineal care, dysfunctional labor). When appropriate, results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Results were limited to the last 10 years. Searches were updated on a regular basis and incorporated in the guideline up to June 15, 2015. VALUES: The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). SUMMARY STATEMENTS: RECOMMENDATIONS.

Prise en charge du travail spontané chez les femmes en santé, à terme.

OBJECTIF: La présente directive vise à fournir des conseils concernant la prise en charge du travail spontané intrapartum, normal ou anormal, à terme, chez les femmes en santé, ainsi que des conseils relatifs à la prise en charge de la dystocie lors du premier et du deuxième stade du travail, pour favoriser l'accouchement vaginal et optimiser les issues de la grossesse. DONNéES PROBANTES: Des documents publiés ont été récupérés au moyen de recherches effectuées dans PubMed et la Cochrane Library, en octobre 2011, à partir d'une terminologie appropriée et contrôlée (p. ex., labour pain; labour, obstetric; dystocia) et de mots-clés (p. ex., obstetric labor, perineal care, dysfunctional labor). Lorsque cela convenait, on n'a tenu compte que des résultats qui proviennent de revues systématiques, d'essais contrôlés aléatoires ou d'essais cliniques contrôlés et d'études d'observation. Seuls les résultats des 10 dernières années ont été pris en considération; les recherches ont été régulièrement mises à jour jusqu'au 15 juin 2015 et intégrées à la directive. VALEURS: La qualité des données probantes a été évaluée en fonction des critères décrits dans le Rapport du Groupe d'étude canadien sur les soins de santé préventifs (tableau 1). DéCLARATIONS SOMMAIRES: RECOMMANDATIONS.

The Management of Nausea and Vomiting of Pregnancy.

OBJECTIVES: To review the evidence-based management of nausea and vomiting of pregnancy and hyperemesis gravidarum. EVIDENCE: MEDLINE and Cochrane database searches were performed using the medical subject headings of treatment, nausea, vomiting, pregnancy, and hyperemesis gravidarum. The quality of evidence reported in these guidelines has been described using the Evaluation of Evidence criteria outlined in the Report of the Canadian Task Force on Preventative Health Care. BENEFITS: Nausea and vomiting of pregnancy has a profound effect on women's health and quality of life during pregnancy as well as a financial impact on the health care system, and its early recognition and management is recommended. COST: Costs, including hospitalizations, additional office visits, and time lost from work, may be reduced if nausea and vomiting in pregnancy is treated early.
