RESUMEN
BACKGROUND: Research on the impact of the COVID-19 pandemic on mothers/childbearing parents has mainly been cross-sectional and focused on psychological symptoms. This study examined the impact on function using ongoing, systematic screening of a representative Ontario sample. METHODS: An interrupted time series analysis of repeated cross-sectional data from a province-wide screening program using the Healthy Babies Healthy Children (HBHC) tool assessed changes associated with the pandemic at the time of postpartum discharge from hospital. Postal codes were used to link to neighborhood-level data. The ability to parent or care for the baby/child and other psychosocial and behavioral outcomes were assessed. RESULTS: The co-primary outcomes of inability to parent or care for the baby/child were infrequently observed in the pre-pandemic (March 9, 2019-March 15, 2020) and initial pandemic periods (March 16, 2020-March 23, 2021) (parent 209/63,006 (0.33%)-177/56,117 (0.32%), care 537/62,955 (0.85%)-324/56,086 (0.58%)). Changes after pandemic onset were not observed for either outcome although a significant (p = 0.02) increase in slope was observed for inability to parent (with questionable clinical significance). For secondary outcomes, worsening was only seen for reported complications during labor/delivery. Significant improvements were observed in the likelihood of being unable to identify a support person to assist with care, need of newcomer support, and concerns about money over time. CONCLUSIONS: There were no substantive changes in concerns about ability to parent or care for children. Adverse impacts of the pandemic may have been mitigated by accommodations for remote work and social safety net policies.
RESUMEN
OBJECTIVE: Knowledge regarding the antecedent clinical and social factors associated with maternal death around the time of pregnancy is limited. This study identified distinct subgroups of maternal deaths using population-based coroner's data, and that may inform ongoing preventative initiatives. METHODS: A detailed review of coroner's death files was performed for all of Ontario, Canada, where there is a single reporting mechanism for maternal deaths. Deaths in pregnancy, or within 365 days thereafter, were identified within the Office of the Chief Coroner for Ontario database, 2004-2020. Variables related to the social and clinical circumstances surrounding the deaths were abstracted in a standardized manner from each death file, including demographics, forensic information, nature and cause of death, and antecedent health and health care factors. These variables were then entered into a latent class analysis (LCA) to identify distinct types of deaths. RESULTS: Among 273 deaths identified in the study period, LCA optimally identified three distinct subgroups, namely, (1) in-hospital deaths arising during birth or soon thereafter (52.7% of the sample); (2) accidents and unforeseen obstetric complications also resulting in infant demise (26.3%); and (3) out-of-hospital suicides occurring postpartum (21.0%). Physical injury (22.0%) was the leading cause of death, followed by hemorrhage (16.8%) and overdose (13.3%). CONCLUSION: Peri-pregnancy maternal deaths can be classified into three distinct sub-types, with somewhat differing causes. These findings may enhance clinical and policy development aimed at reducing pregnancy mortality.

BACKGROUND: Nearly 30 years post legalisation and introduction, midwifery is still not optimally integrated within the health system of Canada's largest province, Ontario. Funding models have been identified as one of the main barriers. METHODS: Using a constructivist perspective, we conducted a qualitative descriptive study to examine how antepartum, intrapartum, and postpartum funding arrangements in Ontario impact midwifery integration. We conceptualized optimal 'integration' as circumstances in which midwives' knowledge, skills, and model of care are broadly respected and fully utilized, interprofessional collaboration and referral support the best possible care for patients, and midwives feel a sense of belonging within hospitals and the greater health system. We collected data through semi-structured telephone interviews with midwives, obstetricians, family physicians, and nurses. The data was examined using thematic analysis. RESULTS: We interviewed 20 participants, including 5 obstetricians, 5 family physicians, 5 midwives, 4 nurses, and 1 policy expert. We found that while course-of-care-based midwifery funding is perceived to support high levels of midwifery client satisfaction and excellent clinical outcomes, it lacks flexibility. This limits opportunities for interprofessional collaboration and for midwives to use their knowledge and skills to respond to health system gaps. The physician fee-for-service funding model creates competition for births, has unintended consequences that limit midwives' scope and access to hospital privileges, and fails to appropriately compensate physician consultants, particularly as midwifery volumes grow. Siloing of midwifery funding from hospital funding further restricts innovative contributions from midwives to respond to community healthcare needs. CONCLUSIONS: Significant policy changes, such as adequate remuneration for consultants, possibly including salary-based physician funding; flexibility to compensate midwives for care beyond the existing course of care model; and a clearly articulated health human resource plan for sexual and reproductive care are needed to improve midwifery integration.

OBJECTIVE: To determine the population-level impact of COVID-19 pandemic-related obstetric practice changes on maternal and newborn outcomes. METHODS: Segmented regression analysis examined changes that occurred 240 weeks pre-pandemic through the first 32 weeks of the pandemic using data from Ontario's Better Outcomes Registry & Network. Outcomes included birth location, length of stay, labour analgesia, mode of delivery, preterm birth, and stillbirth. Immediate and gradual effects were modelled with terms representing changes in intercepts and slopes, corresponding to the start of the pandemic. RESULTS: There were 799 893 eligible pregnant individuals included in the analysis; 705 767 delivered in the pre-pandemic period and 94 126 during the pandemic wave 1 period. Significant immediate decreases were observed for hospital births (relative risk [RR] 0.99; 95% CI 0.98-0.99), length of stay (median change -3.29 h; 95% CI -3.81 to -2.77), use of nitrous oxide (RR 0.11; 95% CI 0.09-0.13) and general anesthesia (RR 0.69; 95% CI 0.58- 0.81), and trial of labour after cesarean (RR 0.89; 95% CI 0.83-0.96). Conversely, there were significant immediate increases in home births (RR 1.35; 95% CI 1.21-1.51), and use of epidural (RR 1.02; 95% CI 1.01-1.04) and regional anesthesia (RR 1.01; 95% CI 1.01-1.02). There were no significant immediate changes for any other outcomes, including preterm birth (RR 0.99; 95% CI 0.93-1.05) and stillbirth (RR 1.11; 95% CI 0.87-1.42). CONCLUSION: Provincial health system changes implemented at the start of the pandemic resulted in immediate clinical practice changes but not insignificant increases in adverse outcomes.

Importance: There are limited high-quality, population-level data about the effect of SARS-CoV-2 infection on pregnancy using contemporaneous comparator cohorts. Objectives: To describe maternal and perinatal outcomes associated with SARS-CoV-2 infection in pregnancy and to assess variables associated with severe disease in the pregnant population. Design, Setting, and Participants: CANCOVID-Preg is an observational surveillance program for SARS-CoV-2-affected pregnancies in Canada. This analysis presents exploratory, population-level data from 6 Canadian provinces for the period of March 1, 2020, to October 31, 2021. A total of 6012 pregnant persons with a positive SARS-CoV-2 polymerase chain reaction test result at any time in pregnancy (primarily due to symptomatic presentation) were included and compared with 2 contemporaneous groups including age-matched female individuals with SARS-CoV-2 and unaffected pregnant persons from the pandemic time period. Exposure: SARS-CoV-2 infection during pregnancy. Incident infections in pregnancy were reported to CANCOVID-Preg by participating provinces/territories. Main Outcomes and Measures: Maternal and perinatal outcomes associated with SARS-CoV-2 infection as well as risk factors for severe disease (ie, disease requiring hospitalization, admission to an intensive care unit/critical care unit, and/or oxygen therapy). Results: Among 6012 pregnant individuals with SARS-CoV-2 in Canada (median age, 31 [IQR, 28-35] years), the greatest proportion of cases were diagnosed at 28 to 37 weeks' gestation (35.7%). Non-White individuals were disproportionately represented. Being pregnant was associated with a significantly increased risk of SARS-CoV-2-related hospitalization compared with SARS-CoV-2 cases among all women aged 20 to 49 years in the general population of Canada (7.75% vs 2.93%; relative risk, 2.65 [95% CI, 2.41-2.88]) as well as an increased risk of intensive care unit/critical care unit admission (2.01% vs 0.37%; relative risk, 5.46 [95% CI, 4.50-6.53]). Increasing age, preexisting hypertension, and greater gestational age at diagnosis were significantly associated with worse maternal outcomes. The risk of preterm birth was significantly elevated among SARS-CoV-2-affected pregnancies (11.05% vs 6.76%; relative risk, 1.63 [95% CI, 1.52-1.76]), even in cases of milder disease not requiring hospitalization, compared with unaffected pregnancies during the same time period. Conclusions and Relevance: In this exploratory surveillance study conducted in Canada from March 2020 to October 2021, SARS-CoV-2 infection during pregnancy was significantly associated with increased risk of adverse maternal outcomes and preterm birth.

Importance: There is limited comparative epidemiological evidence on outcomes associated with COVID-19 vaccination during pregnancy; monitoring pregnancy outcomes in large populations is required. Objective: To evaluate peripartum outcomes following COVID-19 vaccination during pregnancy. Design, Setting, and Participants: Population-based retrospective cohort study in Ontario, Canada, using a birth registry linked with the provincial COVID-19 immunization database. All births between December 14, 2020, and September 30, 2021, were included. Exposures: COVID-19 vaccination during pregnancy, COVID-19 vaccination after pregnancy, and no vaccination. Main Outcomes and Measures: Postpartum hemorrhage, chorioamnionitis, cesarean delivery (overall and emergency cesarean delivery), admission to neonatal intensive care unit (NICU), and low newborn 5-minute Apgar score (<7). Linear and robust Poisson regression was used to generate adjusted risk differences (aRDs) and risk ratios (aRRs), respectively, comparing cumulative incidence of outcomes in those who received COVID-19 vaccination during pregnancy with those vaccinated after pregnancy and those with no record of COVID-19 vaccination at any point. Inverse probability of treatment weights were used to adjust for confounding. Results: Among 97â¯590 individuals (mean [SD] age, 31.9 [4.9] years), 22â¯660 (23%) received at least 1 dose of COVID-19 vaccine during pregnancy (63.6% received dose 1 in the third trimester; 99.8% received an mRNA vaccine). Comparing those vaccinated during vs after pregnancy (n = 44â¯815), there were no significantly increased risks of postpartum hemorrhage (incidence: 3.0% vs 3.0%; aRD, -0.28 per 100 individuals [95% CI, -0.59 to 0.03]; aRR, 0.91 [95% CI, 0.82-1.02]), chorioamnionitis (0.5% vs 0.5%; aRD, -0.04 per 100 individuals [95% CI, -0.17 to 0.09]; aRR, 0.92 [95% CI, 0.70-1.21]), cesarean delivery (30.8% vs 32.2%; aRD, -2.73 per 100 individuals [95% CI, -3.59 to -1.88]; aRR, 0.92 [95% CI, 0.89-0.95]), NICU admission (11.0% vs 13.3%; aRD, -1.89 per 100 newborns [95% CI, -2.49 to -1.30]; aRR, 0.85 [95% CI, 0.80-0.90]), or low Apgar score (1.8% vs 2.0%; aRD, -0.31 per 100 newborns [95% CI, -0.56 to -0.06]; aRR, 0.84 [95% CI, 0.73-0.97]). Findings were qualitatively similar when compared with individuals who did not receive COVID-19 vaccination at any point (n = 30â¯115). Conclusions and Relevance: In this population-based cohort study in Ontario, Canada, COVID-19 vaccination during pregnancy, compared with vaccination after pregnancy and with no vaccination, was not significantly associated with increased risk of adverse peripartum outcomes. Study interpretation should consider that the vaccinations received during pregnancy were primarily mRNA vaccines administered in the second and third trimester.

Importance: Seasonal influenza vaccination in pregnancy can reduce influenza illness among pregnant women and newborns. Evidence is limited on whether seasonal influenza vaccination in pregnancy is associated with adverse childhood health outcomes. Objective: To assess the association between maternal influenza vaccination during pregnancy and early childhood health outcomes. Design, Setting, and Participants: Retrospective cohort study, using a birth registry linked with health administrative data. All live births in Nova Scotia, Canada, between October 1, 2010, and March 31, 2014, were included, with follow-up until March 31, 2016. Adjusted hazard ratios (HRs) and incidence rate ratios (IRRs) with 95% confidence intervals were estimated while controlling for maternal medical history and other potential confounders using inverse probability of treatment weighting. Exposures: Seasonal influenza vaccination during pregnancy. Main Outcomes and Measures: Childhood outcomes studied were immune-related (eg, asthma, infections), non-immune-related (eg, neoplasms, sensory impairment), and nonspecific (eg, urgent or inpatient health care utilization), measured from emergency department and hospitalization databases. Results: Among 28â¯255 children (49% female, 92% born at ≥37 weeks' gestation), 10â¯227 (36.2%) were born to women who received seasonal influenza vaccination during pregnancy. During a mean follow-up of 3.6 years, there was no significant association between maternal influenza vaccination and childhood asthma (incidence rate, 3.0 vs 2.5 per 1000 person-years; difference, 0.53 per 1000 person-years [95% CI, -0.15 to 1.21]; adjusted HR, 1.22 [95% CI, 0.94 to 1.59]), neoplasms (0.32 vs 0.26 per 1000 person-years; difference, 0.06 per 1000 person-years [95% CI, -0.16 to 0.28]; adjusted HR, 1.26 [95% CI, 0.57 to 2.78]), or sensory impairment (0.80 vs 0.97 per 1000 person-years; difference, -0.17 per 1000 person-years [95% CI, -0.54 to 0.21]; adjusted HR, 0.82 [95% CI, 0.49 to 1.37]). Maternal influenza vaccination in pregnancy was not significantly associated with infections in early childhood (incidence rate, 184.6 vs 179.1 per 1000 person-years; difference, 5.44 per 1000 person-years [95% CI, 0.01 to 10.9]; adjusted IRR, 1.07 [95% CI, 0.99 to 1.15]) or with urgent and inpatient health services utilization (511.7 vs 477.8 per 1000 person-years; difference, 33.9 per 1000 person-years [95% CI, 24.9 to 42.9]; adjusted IRR, 1.05 [95% CI, 0.99 to 1.16]). Conclusions and Relevance: In this population-based cohort study with mean follow-up duration of 3.6 years, maternal influenza vaccination during pregnancy was not significantly associated with an increased risk of adverse early childhood health outcomes.

BACKGROUND: In 2002, the MOREOB (Managing Obstetrical Risk Efficiently) obstetrical patient safety program was phased-in across hospitals in Ontario, Canada. The purpose of our study was to evaluate the effect of the MOREOB program on rates of adverse maternal and neonatal outcomes. METHODS: A retrospective cohort study, using province-wide administrative hospitalization data. We included maternal and neonatal records between fiscal years 2002-2003 and 2013-2014, for deliveries taking place at the 67 Ontario hospitals where the MOREOB program was implemented between 2002 and 2012. After accounting for institutional mergers and excluding very small hospitals, 55 hospitals (1,447,073 deliveries) were included. Multivariable logistic and linear mixed effects regression analysis were used, accounting for secular trends, within hospital correlation and over time correlation, and adjusting for a maternal comorbidity index, hospital annual birth volume, and level of care. The main outcome measure was a composite individual-level indicator of incidence of any adverse events, and a hospital-level score, called the Weighted Adverse Outcome Score (WAOS) capturing both maternal and neonatal adverse outcomes. RESULTS: Across the 12 years of follow up, there were 98,789 adverse maternal and neonatal outcomes, a rate of 6.83 per 100 deliveries (6.66 per 100 occurring before, 6.91 per 100 during, and 6.84 per 100 after program implementation). The multivariable analysis found no statistically significant decrease in adverse events associated with program implementation (OR for adverse events after versus before =1.11 (95% CI: 1.06 to 1.17, change in mean WAOS score after minus before =0.15 (- 0.36 to 0.67)). CONCLUSIONS: We did not find a reduction in the incidence of maternal and neonatal adverse outcomes associated with the MOREOB program, and small yet statistically significant increases in some adverse events were observed.

A reduction in maternal mortality has traditionally been used as a critical measure of progress in improving maternal health, and the maternal mortality ratio is one of the main indicators of a country's status in the area. In Canada, maternal mortality is infrequent yet devastating. In many cases, there were no interventions that could have saved the mother's life, but in others, there were opportunities for prevention. There is absolute consensus that the upper limit for a preventable maternal death is zero. The World Health Organization's 2010 report indicated a rise in Canada's maternal mortality and prompted the Society of Obstetricians and Gynaecologists of Canada to work with partners to review national maternal mortality surveillance. Since then, efforts have begun and stalled. We are now in the fortunate position to work with experts and provincial leaders to implement a national system of confidential enquiry into maternal deaths and severe maternal morbidity in Canada. Canada's existing data do not tell the true story of maternal deaths; we cannot learn from each death and its circumstance to identify measures for prevention in the future. Dedicated leaders have been working hard to leverage their collective expertise. Recommendations for definitions, processes, knowledge translation tools, and programs that raise awareness about maternal mortality in Canada have been developed and are being piloted. It is anticipated that, with the appropriate support and appropriate leadership, Canada will have the foundation of a national confidential enquiry system into maternal deaths very soon. This is an update on progress.

BACKGROUND: MOREOB (Managing Obstetrical Risk Efficiently) is a patient safety program for health care providers and administrators in hospital obstetric units. MOREOB has been implemented widely in Canada and gradually spread to the United States. The main goal of MOREOB is to build a patient safety culture and improve clinical outcomes. In 2013, 26 Ontario hospitals voluntarily accepted provincial funding to participate in MOREOB. The purpose of our study was to assess the effect of MOREOB on participant knowledge, organizational culture, and experiences implementing and participating in the program at these 26 Ontario hospitals. METHODS: A convergent parallel mixed-methods study in Ontario, Canada, with MOREOB participants from 26 hospitals. The quantitative component used a descriptive pre-post repeated measures design to assess participant knowledge and perception of culture, administered pre-MOREOB and after each of the three MOREOB modules. Changes in mean scores were assessed using mixed-effects regression. The qualitative component used a qualitative descriptive design with individual semi-structured interviews. We used content analysis to code, categorize, and thematically describe data. A convergent parallel design was used to triangulate findings from data sources. RESULTS: 308 participants completed the knowledge test, and 329 completed the culture assessment at all four time points. Between baseline and post-Module 3, statistically significant increases on both scores were observed, with an increase of 7.9% (95% CI: 7.1 to 8.8) on the knowledge test and an increase of 0.45 (on a scale of 1-5, 95% CI: 0.38 to 0.52) on the culture assessment. Interview participants (n = 15) described improvements in knowledge, interprofessional communication, ability to provide safe care, and confidence in skills. Facilitators and barriers to program implementation and sustainability were identified. CONCLUSIONS: Participants were satisfied with their participation in the MOREOB program and perceived that it increased health care provider knowledge and confidence, improved safety for patients, and improved communication between team members. Additionally, mean scores on knowledge tests for obstetric content and culture assessment improved. The MOREOB program can help organizations and individuals improve care by concentrating on the human and organizational aspects of patient safety. Further work to improve program implementation and sustainability is required.

BACKGROUND: Ontario's birth Registry (BORN) was established in 2009 to collect, interpret, and share critical data about pregnancy, birth and the early childhood period to facilitate and improve the provision of healthcare. Since the use of routinely-collected health data has been prioritized internationally by governments and funding agencies to improve patient care, support health system planning, and facilitate epidemiological surveillance and research, high quality data is essential. The purpose of this study was to verify the accuracy of a selection of data elements that are entered in the Registry. METHODS: Data quality was assessed by comparing data re-abstracted from patient records to data entered into the Ontario birth Registry. A purposive sample of 10 hospitals representative of hospitals in Ontario based on level of care, birth volume and geography was selected and a random sample of 100 linked mother and newborn charts were audited for each site. Data for 29 data elements were compared to the corresponding data entered in the Ontario birth Registry using percent agreement, kappa statistics for categorical data elements and intra-class correlation coefficients (ICCs) for continuous data elements. RESULTS: Agreement ranged from 56.9 to 99.8%, but 76% of the data elements (22 of 29) had greater than 90% agreement. There was almost perfect (kappa 0.81-0.99) or substantial (kappa 0.61-0.80) agreement for 12 of the categorical elements. Six elements showed fair-to-moderate agreement (kappa <0.60). We found moderate-to-excellent agreement for four continuous data elements (ICC >0.50). CONCLUSION: Overall, the data elements we evaluated in the birth Registry were found to have good agreement with data from the patients' charts. Data elements that showed moderate kappa or low ICC require further investigation.

PURPOSE: Since 2012, BORN Ontario, a maternal-newborn registry, has collected data on every birth in Ontario. To ensure data quality, we assessed the reliability of key elements collected in BORN by comparing these with like data elements in the Canadian Institute for Health Information-Discharge Abstract Database (CIHI-DAD). METHODS: We used provincial health card numbers to deterministically link live or stillbirth records and their corresponding mothers' records in the BORN database to the CIHI-DAD in the fiscal years 2012-2013 to 2014-2015. Percentage agreement and Cohen Kappa statistics were used to assess agreement on main elements in both databases. RESULTS: The percentage agreement and Kappa coefficients were 99.98% and 0.740 (95% CI: 0.677-0.803) on live/stillbirth, respectively. The Kappa coefficients for infant sex, gestational age at birth, induction of labour, and caesarean birth were 0.989 (95% CI: 0.988-0.989), 0.920 (95% CI: 0.919-0.920), 0.782 (95% CI: 0.780-0.785), and 0.995 (95% CI: 0.995-0.996), respectively. Kappa agreement for the number of fetuses in a pregnancy was 0.979 (95% CI: 0.977-0.981). Percentage agreement was very high for infants' birthdates (99.9%), infant postal codes (91.8%), infants' birth weight in grams (95.5%), and mothers' dates of birth (99.1%). CONCLUSIONS: Overall, the BORN and CIHI-DAD databases had concordance on key birth and maternal data elements; however, additional work is needed to understand discrepancies identified.

BACKGROUND: Intermittent Auscultation (IA) is the recommended method of fetal surveillance for healthy women in labour. However, the majority of women receive continuous electronic monitoring. We used the Theoretical Domains Framework (TDF) to explore the views of Birthing Unit nurses about using IA as their primary method of fetal surveillance for healthy women in labour. METHODS: Using a semi-structured interview guide, we interviewed a convenience sample of birthing unit nurses throughout Ontario, Canada to elicit their views about fetal surveillance. Interviews were recorded and transcribed verbatim. Transcripts were content analysed using the TDF and themes were framed as belief statements. Domains potentially key to changing fetal surveillance behaviour and informing intervention design were identified by noting the frequencies of beliefs, content, and their reported influence on the use of IA. RESULTS: We interviewed 12 birthing unit nurses. Seven of the 12 TDF domains were perceived to be key to changing birthing unit nurses' behaviour The nurses reported that competing tasks, time constraints and the necessity to multitask often limit their ability to perform IA (domains Beliefs about capabilities; Environmental context and resources). Some nurses noted the decision to use IA was something that they consciously thought about with every patient while others stated it their default decision as long as there were no risk factors (Memory, attention and decision processes, Nature of behaviour). They identified positive consequences (e.g. avoid unnecessary interventions, mother-centered care) and negative consequences of using IA (e.g. legal concerns) and reported that the negative consequences can often outweigh positive consequences (Beliefs about consequences). Some reported that hospital policies and varying support from care teams inhibited their use of IA (Social influences), and that support from the entire team and hospital management would likely increase their use (Social influences; Behavioural regulation). CONCLUSION: We identified potential influences on birthing unit nurses' use of IA as their primary method of fetal surveillance. These beliefs suggest potential targets for behaviour change interventions to promote IA use.

OBJECTIVE: There is concern that obstetric interventions (prelabor cesarean section and induced delivery) are drivers of late preterm (LP) birth. Our objective was to evaluate the independent association between obstetric interventions and LP birth and explore associated independent maternal and fetal risk factors for LP birth. STUDY DESIGN: In this population-based cross-sectional study, the BORN Information System was used to identify all infants born between 34 and 40 completed weeks of gestation between 2005 and 2012 in Ontario, Canada. The association between obstetric interventions (preterm cesarean section and induced delivery) and LP birth (34 to 36 completed weeks' gestation vs 37 to 40 completed weeks' gestation) was assessed using generalized estimating equation regression. RESULTS: Of 917,013 births between 34 and 40 weeks, 49,157 were LP (5.4%). In the adjusted analysis, "any obstetric intervention" (risk ratio [RR], 0.65; 95% confidence interval [CI], 0.57-0.74), induction (RR, 0.71; 95% CI, 0.61-0.82) and prelabor cesarean section (RR, 0.66; 95% CI, 0.59-0.74) were all associated with a lower likelihood of LP vs term birth. Several independent potentially modifiable risk factors for LP birth were identified including previous cesarean section (RR, 1.28; 95% CI, 1.16-1.40), smoking during pregnancy (RR, 1.28; 95% CI, 1.21-1.36) and high material (RR, 1.1; 95% CI, 1.03-1.18) and social (RR, 1.09; 95% CI, 1.02-1.16) deprivation indices. CONCLUSION: After accounting for differences in maternal and fetal risk, LP births had a 35% lower likelihood of obstetric interventions than term births. Obstetric care providers may be preferentially avoiding induction and prelabor cesarean section between 34 and 37 weeks' gestation.

BACKGROUND: In 2009 the Ontario Ministry of Health and Long Term Care funded the implementation of province-wide fetal fibronectin testing in Ontario hospitals. This paper reports results from the provincial evaluation that sought to describe the experience of fetal fibronectin testing from the perspective of women with symptoms of preterm labour. METHODS: A descriptive qualitative design was used, employing semi-structured telephone and face-to-face interviews with women who had fetal fibronectin testing. RESULTS: Five hospitals participated in recruiting women for the study and 17 women were interviewed. Women described their experiences of fetal fibronectin testing as an emotional process that moves from expecting, to feeling, to hoping for reassurance; and then to re-defining what is required to feel reassured. Women described feeling anxious while waiting for fetal fibronectin results. When test results were negative, women described feeling a sense of relief that their symptoms would not likely lead to an imminent preterm birth. Women with positive results expressed feeling reassured by the care decisions and quick action taken by the health care team. CONCLUSION: Fetal fibronectin testing was acceptable and beneficial to these women with symptoms of preterm labour. Implications for practice and future research are suggested.

INTRODUCTION: In 2007, the Canadian Paediatric Society (CPS) published guidelines aimed at preventing severe hyperbilirubinemia. OBJECTIVES: To determine whether hospitals had implemented these guidelines; to investigate how guideline-recommended care is organized; and to understand the factors influencing guideline implementation. METHODS: The present study was an online survey conducted from December 2011 to May 2012 of all Ontario hospitals offering maternal-newborn services. RESULTS: A total of 97 of 100 eligible hospitals responded. Seventy-seven of the 97 (79%) respondents reported having implemented universal neonatal bilirubin screening. Among these hospitals, hospital-based postdischarge follow-up was reported more frequently than follow-up at community-based locations: hospital laboratory (n=40 [52%]), mother-baby care unit (n=32 [42%]), outpatient clinic (n=25 [33%]), primary care provider in community (n=19 [25%]) and community laboratory (n=8 [10%]). The CPS guidelines were the most frequently reported factor influencing implementation (n=74 [96%]). DISCUSSION: The survey provides valuable insight into the impact of a complex guideline in Canada's largest province. There was heterogeneity in how hospitals organized services, but there was a notable trend toward hospital-based postdischarge care. The shift to hospital-based care runs counter to current health policy directions and highlights the lack of integration among health care sectors. CONCLUSION: The majority of Ontario hospitals implemented universal bilirubin screening following the release of the CPS guidelines. Further analysis is needed to determine the impact that the guidelines and the differences in implementation have had on clinical outcomes and the utilization of health services.
INTRODUCTION: En 2007, la Société canadienne de pédiatrie (SCP) a publié des lignes directrices afin de prévenir l'hyperbilirubinémie grave. OBJECTIFS: Déterminer si les hôpitaux ont adopté ces lignes directrices, examiner l'organisation des soins recommandée dans les lignes directrices et comprendre les facteurs qui influent sur la mise en Åuvre des lignes directrices. MÉTHODOLOGIE: La présente étude rend compte d'une enquête virtuelle menée de décembre 2011 à mai 2012 auprès de tous les hôpitaux ontariens offrant des services mère-enfant. RÉSULTATS: Au total, 97 des 100 hôpitaux admissibles ont répondu à l'enquête. Soixante-dix-sept des 97 répondants (79 %) ont déclaré avoir adopté le dépistage universel de la bilirubine néonatale. Dans ces hôpitaux, le suivi en milieu hospitalier après le congé était plus fréquent que le suivi en milieu communautaire : laboratoire de l'hôpital (n=40 [52 %]), unité de soins mère-enfant (n=32 [42 %]), consultations externes (n=25 [33 %]), dispensateur de soins de première ligne en milieu communautaire (n=19 [25 %]) et laboratoire en milieu communautaire (n=8 [10 %]). Les lignes directrices de la SCP étaient le plus souvent invoquées comme le facteur ayant suscité cette mise en Åuvre (n=74 [96 %]). EXPOSÉ: L'enquête donne un aperçu précieux des répercussions de lignes directrices complexes dans la plus grande province canadienne. On a remarqué une organisation hétérogène des services dans les hôpitaux, mais une tendance nette vers des soins en milieu hospitalier après le congé. Le passage à des soins en milieu hospitalier va à l'encontre des directives de santé actuelles et fait ressortir l'absence d'intégration entre les secteurs de soins. CONCLUSION: La majorité des hôpitaux ontariens a adopté le dépistage universel de la bilirubine après la publication des lignes directrices de la SCP. Il faudra effectuer une analyse plus approfondie pour déterminer les répercussions de ces lignes directrices et des divers modes de mise en Åuvre sur les résultats cliniques et l'utilisation des services de santé.
RESUMEN
OBJECTIVE: This study was undertaken to examine the association between maternal oseltamivir treatment for influenza and infant outcomes during the 2009 HINI influenza pandemic. STUDY DESIGN: This was a retrospective cohort study using a population-based maternal newborn database including women who gave birth to a singleton infant in the Canadian province of Ontario from November 2009 through April 2010. Risks of small for gestational age (SGA) (10th percentile and 3rd percentile), preterm birth (<37 weeks of gestation), very preterm birth (<32 weeks of gestation), and 5-minute Apgar score <7 associated with maternal exposure to oseltamivir were analyzed by multivariable regression. RESULTS: A total of 55,355 women with a singleton birth were included in this study. Among them, 1237 (2.2%) women received oseltamivir for treatment or prevention of influenza during pregnancy. Women who took oseltamivir during pregnancy were less likely to have a SGA infant based on the 10th percentile for growth (adjusted risk ratio, 0.77; 95% confidence interval, 0.60-0.98). No association between maternal use of oseltamivir with SGA on 3rd percentile, preterm birth, very preterm birth, and low Apgar score was observed. CONCLUSION: There is no evidence of an association between maternal use of oseltamivir for influenza and early birth, low Apgar at birth, and poor fetal growth.

OBJECTIVE: Elective repeat Caesarean section (ERCS) for low-risk women at < 39 weeks' gestation has consistently been associated with increased risks to the neonate, including respiratory morbidity, NICU admission, and lengthier hospital stays than ERCS at 39 to 40 weeks' gestation. The objective of this quality improvement project was to reduce high rates of ERCS < 39 weeks across the Eastern Ontario region. METHODS: All hospitals within the region providing care during labour and birth (n = 10) were asked to participate. Representatives from each hospital received information about their site-specific rates and knowledge-translation resources to assist them with the project. A benchmark rate for ERCS < 39 weeks was set at 30%. The rates of ERCS < 39 weeks were calculated for two different times (the 2009-2010 and 2010-2011 fiscal years) and the relative difference and 95% confidence intervals were calculated to quantify the magnitude and statistical significance of any change. Qualitative interviews were completed with key informants from each hospital. RESULTS: The proportion of ERCS at < 39 weeks' gestation across the region in the fiscal year 2010-2011 (n = 197/497; 39.6%) was significantly decreased (relative difference: -21%; 95% CI -31% to -8%, P = 0.002) from the previous fiscal year 2009-2010 (n = 229/459; 49.9%). A number of barriers to, and facilitators of, practice change were identified. CONCLUSION: A reduction in the rate of ERCS < 39 weeks among low-risk women was achieved across the region. Awareness of the issue, possession of site-specific data, and agreement about the evidence and the need for change are critical first steps to improving practice.
Objectif : La césarienne itérative planifiée (CIP) menée chez des femmes exposées à de faibles risques à < 39 semaines de gestation a régulièrement été associée à plus de risques pour le nouveau-né (dont une morbidité respiratoire, une admission à l'UNSI et une hospitalisation prolongée) que la CIP menée entre 39 et 40 semaines de gestation. Ce projet d'amélioration de la qualité avait pour objectif d'atténuer les taux élevés de CIP menée à < 39 semaines dans la région de l'est de l'Ontario. Méthodes : La participation de tous les hôpitaux de la région offrant des soins au cours du travail et de l'accouchement (n = 10) a été sollicitée. Des représentants de chacun de ces hôpitaux ont reçu des ressources d'application des connaissances pour les aider à mettre en Åuvre le projet, ainsi que des renseignements au sujet des taux associés à leurs établissements respectifs. Un taux de référence de 30 % a été établi pour ce qui est de la CIP à < 39 semaines. Les taux de CIP à < 39 semaines ont été calculés pour deux périodes différentes (les exercices financiers 20092010 et 20102011); la différence relative et les intervalles de confiance à 95 % ont été calculés pour quantifier l'ampleur et l'importance statistique de tout changement. Des entrevues qualitatives ont été menées auprès d'intervenants clés de chacun des hôpitaux. Résultats : La proportion de CIP à < 39 semaines de gestation au sein de la région au cours de l'exercice financier 20102011 (n = 197/497; 39,6 %) a connu une baisse significative (différence relative : −21 %; IC à 95 %, −31 % - −8 %, P = 0,002) par comparaison avec l'exercice financier précédent 20092010 (n = 229/459; 49,9 %). Un certain nombre d'obstacles et de facteurs facilitants en matière de modification de la pratique ont été identifiés. Conclusion : Une baisse du taux de CIP à < 39 semaines chez les femmes exposées à de faibles risques a été obtenue au sein de la région. La sensibilisation à cette question, la détention de données propres à l'établissement et l'atteinte d'un consensus quant aux données et à la nécessité du changement font partie des premières étapes cruciales du processus d'amélioration de la pratique.

BACKGROUND: Sequential use of vacuum and obstetric forceps for vaginal delivery is associated with increased risks of adverse maternal and infant outcomes. METHODS: We conducted a retrospective cohort study to estimate the frequency of sequential use of vacuum and forceps for planned vaginal delivery and to identify predictors, using data collected in Ontario between 2004 and 2007. Multivariate logistic regression models were used to estimate the adjusted odds ratios and 95% confidence intervals of predictors of sequential use of vacuum and forceps. RESULTS: Of 186 988 pregnant women with a singleton, vertex presentation at term and a planned vaginal birth, 1062 (0.57%) required the sequential use of vacuum and forceps for delivery. The major predictors for sequential use of vacuum and forceps were mother's primary language being other than English or French, nulliparity, a history of Caesarean section, dystocia, use of epidural or other pain relief, labour induction, labour augmentation, fetal macrosomia, and advanced gestational age. CONCLUSION: In this population-based study we found that 0.57% of planned vaginal births were delivered with sequential use of vacuum and obstetric forceps. Abnormal labour, fetal macrosomia, language barriers, and advanced gestational age are significant predictors of requiring this sequential use.
Contexte : L'utilisation séquentielle d'une ventouse obstétricale et de forceps obstétricaux dans le cadre d'un accouchement vaginal est associée à des risques accrus d'obtenir des issues indésirables maternelles et néonatales. Méthodes : Nous avons mené, au moyen de données recueillies en Ontario entre 2004 et 2007, une étude de cohorte rétrospective en vue d'estimer la fréquence de l'utilisation séquentielle d'une ventouse obstétricale et de forceps dans le cadre d'un accouchement vaginal planifié, et d'identifier des facteurs prédictifs. Des modèles de régression logistique multivariée ont été utilisés pour estimer les rapports de cotes corrigés et les intervalles de confiance à 95 % des facteurs prédictifs de l'utilisation séquentielle d'une ventouse obstétricale et de forceps. Résultats : Chez 186 988 femmes présentant une grossesse monofÅtale en présentation du sommet à terme et ayant connu un accouchement vaginal planifié, 1 062 (0,57 %) ont nécessité l'utilisation séquentielle d'une ventouse obstétricale et de forceps aux fins de l'accouchement. Les principaux facteurs prédictifs de l'utilisation séquentielle d'une ventouse obstétricale et de forceps ont été le fait que la langue maternelle de la mère ne soit pas l'anglais ou le français, la nulliparité, les antécédents de césarienne, la dystocie, l'utilisation d'une péridurale ou d'un autre analgésique, le déclenchement du travail, l'accélération du travail, la macrosomie fÅtale et l'âge gestationnel avancé. Conclusion : Dans le cadre de cette étude en population générale, nous avons constaté que 0,57 % des accouchements vaginaux planifiés ont eu recours à l'utilisation séquentielle d'une ventouse obstétricale et de forceps obstétricaux. Un travail anormal, la macrosomie fÅtale, les obstacles linguistiques et l'âge gestationnel avancé sont des facteurs prédictifs importants de la nécessité d'avoir recours à une telle utilisation séquentielle.

Pregnancy, birth, and the early newborn period are times of high use of health care services. As well as opportunities for providing quality care, there are potential missed opportunities for health promotion, safety issues, and increased costs for the individual and the system when quality is not well defined or measured. There has been a need to identify key performance indicators (KPIs) to measure quality care within the provincial maternal-newborn system. We also wanted to provide automated audit and feedback about these KPIs to support quality improvement initiatives in a large Canadian province with approximately 140 000 births per year. We therefore worked to develop a maternal-newborn dashboard to increase awareness about selected KPIs and to inform and support hospitals and care providers about areas for quality improvement. We mapped maternal-newborn data elements to a quality domain framework, sought feedback via survey for the relevance and feasibility of change, and examined current data and the literature to assist in setting provincial benchmarks. Six clinical performance indicators of maternal-newborn quality care were identified and evidence-informed benchmarks were set. A maternal-newborn dashboard with "drill down" capacity for detailed analysis to enhance audit and feedback is now available for implementation. While audit and feedback does not guarantee individuals or institutions will make practice changes and move towards quality improvement, it is an important first step. Practice change and quality improvement will not occur without an awareness of the issues.
