Abortion Safety and Use with Normally Prescribed Mifepristone in Canada.

BACKGROUND: In the United States, mifepristone is available for medical abortion (for use with misoprostol) only with Risk Evaluation and Mitigation Strategy (REMS) restrictions, despite an absence of evidence to support such restrictions. Mifepristone has been available in Canada with a normal prescription since November 2017. METHODS: Using population-based administrative data from Ontario, Canada, we examined abortion use, safety, and effectiveness using an interrupted time-series analysis comparing trends in incidence before mifepristone was available (January 2012 through December 2016) with trends after its availability without restrictions (November 7, 2017, through March 15, 2020). RESULTS: A total of 195,183 abortions were performed before mifepristone was available and 84,032 after its availability without restrictions. After the availability of mifepristone with a normal prescription, the abortion rate continued to decline, although more slowly than was expected on the basis of trends before mifepristone had been available (adjusted risk difference in time-series analysis, 1.2 per 1000 female residents between 15 and 49 years of age; 95% confidence interval [CI], 1.1 to 1.4), whereas the percentage of abortions provided as medical procedures increased from 2.2% to 31.4% (adjusted risk difference, 28.8 percentage points; 95% CI, 28.0 to 29.7). There were no material changes between the period before mifepristone was available and the nonrestricted period in the incidence of severe adverse events (0.03% vs. 0.04%; adjusted risk difference, 0.01 percentage points; 95% CI, -0.06 to 0.03), complications (0.74% vs. 0.69%; adjusted risk difference, 0.06 percentage points; 95% CI, -0.07 to 0.18), or ectopic pregnancy detected after abortion (0.15% vs. 0.22%; adjusted risk difference, -0.03 percentage points; 95% CI, -0.19 to 0.09). There was a small increase in ongoing intrauterine pregnancy continuing to delivery (adjusted risk difference, 0.08 percentage points; 95% CI, 0.04 to 0.10). CONCLUSIONS: After mifepristone became available as a normal prescription, the abortion rate remained relatively stable, the proportion of abortions provided by medication increased rapidly, and adverse events and complications remained stable, as compared with the period when mifepristone was unavailable.

Inequalities in access to prenatal care during the COVID-19 pandemic: Analysis of a population-based cohort.

BACKGROUND: Before the COVID-19 pandemic, access to prenatal care was lower among some socio-demographic groups. This pandemic caused disruptions to routine preventative care, which could have increased inequalities. OBJECTIVES: To investigate if the COVID-19 pandemic increased inequalities in access to prenatal care among those who are younger, live in rural areas, have a lower socio-economic situation (SES) and are recent immigrants. METHODS: We used linked administrative datasets from ICES to identify a population-based cohort of 455,245 deliveries in Ontario from January 2018 to December 2021. Our outcomes were first-trimester prenatal visits, first-trimester ultrasound and adequacy of prenatal care. We used joinpoint analysis to examine outcome time trends and identify trend change points. We stratified analyses by age, rural residence, SES and recent immigration, and examined risk differences (RD) with 95% confidence intervals (CI) between groups at the beginning and end of the study period. RESULTS: For all outcomes, we noted disruptions to care beginning in March or April 2020 and returning to previous trends by November 2020. Inequalities were stable across groups, except recent immigrants. In July 2017, 65.0% and 69.8% of recent immigrants and non-immigrants, respectively, received ultrasounds in the first trimester (RD -4.8%, 95% CI -8.0, -1.5). By October 2020, this had increased to 75.4%, with no difference with non-immigrants (RD 0.4%, 95% CI -2.4, 3.2). Adequacy of prenatal care showed more intensive care as of November 2020, reflecting a higher number of visits. CONCLUSIONS: We found no evidence that inequalities between socio-economic groups that existed prior to the pandemic worsened after March 2020. The pandemic may be associated with increased access to care for recent immigrants. The introduction of virtual visits may have resulted in a higher number of prenatal care visits.

Diabetes mellitus in pregnancy across Canada.

BACKGROUND: Contemporary estimates of diabetes mellitus (DM) rates in pregnancy are lacking in Canada. Accordingly, this study examined trends in the rates of type 1 (T1DM), type 2 (T2DM) and gestational (GDM) DM in Canada over a 15-year period, and selected adverse pregnancy outcomes. METHODS: This study used repeated cross-sectional data from the Canadian Institute of Health Information (CIHI) hospitalization discharge abstract database (DAD). Maternal delivery records were linked to their respective birth records from 2006 to 2019. The prevalence of T1DM, T2DM and GDM were calculated, including relative changes over time, assessed by a Cochrane-Armitage test. Also assessed were differences between provinces and territories in the prevalence of DM. RESULTS: Over the 15-year study period, comprising 4,320,778 hospital deliveries in Canada, there was a statistically significant increase in the prevalence of GDM and T1DM and T2DM. Compared to pregnancies without DM, all pregnancies with any form of DM had higher rates of hypertension and Caesarian delivery, and also adverse infant outcomes, including major congenital anomalies, preterm birth and large-for-gestational age birthweight. CONCLUSION: Among 4.3 million pregnancies in Canada, there has been a rise in the prevalence of DM. T2DM and GDM are expected to increase further as more overweight women conceive in Canada.

Maternal deaths by suicide and drug overdose in two Canadian provinces; retrospective review.

OBJECTIVE: To identify and review factors associated with maternal deaths by suicide and drug overdose in the Canadian Coroner and Medical Examiners Database (CCMED), from 2017-2019. METHODS: We identified potential maternal deaths in Ontario and British Columbia by searching the CCMED narratives of deaths to females 10 to 60 years old for pregnancy-related terms. Identified narratives were then qualitatively reviewed in quadruplicate to determine if they were maternal deaths by suicide or drug overdose, and to extract information on maternal characteristics, the manner of death, and factors associated with each death. RESULTS: Of the 90 deaths identified in this study, 15 (16.7%) were due to suicide and 20 (22.2%) were due to a drug overdose. These deaths occurred to women of varying ages and across the pregnancy-postpartum period. Among the suicides, 10 were by hanging, and among the overdose-related deaths, 15 had fentanyl detected. Notably, 13 (37.1%) of the 35 deaths to suicide or drug overdose occurred beyond 42 days after pregnancy, 19 (54.3%) followed a miscarriage or induced abortion, and in 23 (65.7%) there was an established history of mental health illness. Substance use disorders were documented in 4 of the 15 suicides (26.7%), and 18 of the 20 overdose-related deaths (90.0%). CONCLUSION: Suicide and drug overdose may contribute more to maternal deaths in Canada than previously realized. Programs are needed to identify women at risk of these outcomes, and to intervene during pregnancy and beyond the conventional postpartum period.

Cardiovascular outcomes in children with Kawasaki disease: a population-based cohort study.

BACKGROUND: The risk of cardiovascular events after Kawasaki disease (KD) remains uncertain. Our objective was to determine the risk of cardiovascular events and mortality after KD. METHODS: Population-based retrospective cohort study using Ontario health administrative databases (0-18 years; 1995-2018). EXPOSURE: pediatric KD hospitalizations. Each case was matched to 100 non-exposed controls. PRIMARY OUTCOME: major adverse cardiac events (MACE; cardiovascular death, myocardial infarction, or stroke composite). SECONDARY OUTCOMES: composite cardiovascular events and mortality. We determined incidence rates and adjusted hazard ratios (aHR) using multivariable Cox models. RESULTS: Among 4597 KD survivors, 79 (1.7%) experienced MACE, 632 (13.8%) composite cardiovascular events, and 9 (0.2%) died during 11-year median follow-up. The most frequent cardiovascular events among KD survivors were ischemic heart disease (4.6 events/1000 person-years) and arrhythmias (4.5/1000 person-years). KD survivors were at increased risk of MACE between 0-1 and 5-10 years, and composite cardiovascular events at all time periods post-discharge. KD survivors had a lower mortality risk throughout follow-up (aHR 0.36, 95% CI 0.19-0.70). CONCLUSION: KD survivors are at increased risk of post-discharge cardiovascular events but have a lower risk of death, which justifies enhanced cardiovascular disease surveillance in these patients. IMPACT: Among 4597 Kawasaki disease (KD) survivors, 79 (1.7%) experienced major adverse cardiac events (MACE) and 632 (13.8%) had composite cardiovascular events during 11-year median follow-up. KD survivors had significantly higher risks of post-discharge MACE and cardiovascular events versus non-exposed children. Only nine KD survivors (0.2%) died during follow-up, and the risk of mortality was significantly lower among KD survivors versus non-exposed children. Childhood KD survivors should receive preventative counseling and cardiovascular surveillance, aiming to mitigate adult cardiovascular disease.

Rates of and factors associated with exclusive and any breastfeeding at six months in Canada: an analysis of population-based cross-sectional data.

BACKGROUND: Breastfeeding has many health, economic and environmental benefits for both the infant and pregnant individual. Due to these benefits, the World Health Organization and Health Canada recommend exclusive breastfeeding for the first six months of life. The purpose of this study is to examine the prevalence of exclusive and any breastfeeding in Canada for at least six months, and factors associated with breastfeeding cessation prior to six months. METHODS: We performed a secondary analysis of breastfeeding-related questions asked on the cross-sectional 2017-2018 Canadian Community Health Survey. Our sample comprised 5,392 females aged 15-55 who had given birth in the five years preceding the survey. Descriptive statistics were carried out to assess the proportion of females exclusively breastfeeding and doing any breastfeeding for at least six months by demographic and behavioural factors. We also assessed, by baby's age, trends in the introduction of solids and liquids, breastfeeding cessation and the reasons females stopped breastfeeding. Multivariate log binominal regression was used to examine the association between breastfeeding at six months and selected maternal characteristics hypothesized a priori to be associated with breastfeeding behaviour. RESULTS: Overall, for at least six months, 35.6% (95% confidence interval (CI): 33.3%-37.8%) of females breastfed exclusively and 62.2% (95% CI: 60.0%-64.4%) did any breastfeeding. The largest decline in exclusive breastfeeding occurred in the first month. Factors most strongly associated with breastfeeding for at least six months were having a bachelor's or higher degree, having a normal body mass index, being married and daily co-sleeping. Insufficient milk supply was given as the most common reason for breastfeeding cessation irrespective of when females stopped breastfeeding. CONCLUSION: Six-month exclusive breastfeeding rates in Canada remain below targets set by the World Health Assembly. Continued efforts, including investment in monitoring of breastfeeding rates, are needed to promote and support exclusive breastfeeding, especially among females vulnerable to early cessation.

A mixed-method study exploring barriers and facilitators to midwives' mental health in Ontario.

BACKGROUND: There is a paucity of information regarding the mental health of midwives working in Ontario, Canada. Many studies have investigated midwives' mental health around the world, but little is known about how the model of midwifery care in Ontario contributes to or negatively impacts midwives' mental health. The aim of the study was to gain a deeper understanding of factors that contribute to and negatively impact Ontario midwives' mental health. METHODS: We employed a mixed-methods, sequential, exploratory design, which utilized focus groups and individual interviews, followed by an online survey. All midwives in Ontario who had actively practiced within the previous 15 months were eligible to participate. FINDINGS: We conducted 6 focus groups and 3 individual interviews, with 24 midwives, and 275 midwives subsequently completed the online survey. We identified four broad factors that impacted midwives' mental health: (1) the nature of midwifery work, (2) the remuneration model, (3) the culture of the profession, and (4) external factors. DISCUSSION: Based on our findings and the existing literature, we have five broad recommendations for improving Ontario midwives' mental health: (1) provide a variety of work options for midwives; (2) address the impacts of trauma on midwives; (3) make mental health services tailored for midwives accessible; (4) support healthy midwife-to-midwife relationships; and (5) support improved respect and understanding of midwifery. CONCLUSION: As one of the first comprehensive investigations into midwives' mental health in Ontario, this study highlights factors that contribute negatively to midwives' mental health and offers recommendations for how midwives' mental health can be improved systemically.

Mediating expectations and experiences that influence birth experiences in Canada's first Alongside Midwifery Unit.

BACKGROUND: Globally, midwifery-led birthing units are associated with excellent maternal and neonatal outcomes, and positive childbirth experiences. However, little is known about what aspects of midwife-led units contribute to favorable experiences and overall satisfaction. Our aim was to explore and describe midwifery service user experiences at Canada's first Alongside Midwifery Unit (AMU). METHODS: We used a qualitative, grounded theory approach using semi-structured interviews with recipients of midwifery care at the AMU. FINDINGS: Data were collected from twenty-eight participants between September 2018 and March 2020. Our generated theory explains how birth experiences and satisfaction were influenced by how well the AMU aligned with expectations or desired experiences related to the following four themes: (1) maintaining the midwifery model of care, (2) emphasizing control and choice, (3) facilitating interprofessional relationships, and (4) appreciating the unique AMU birthing environment. CONCLUSION: Canada's first AMU met or exceeded service-user expectations, resulting in high levels of satisfaction with their birth experience. Maintaining core elements of the midwifery model of care, promoting high levels of autonomy, and facilitating positive interprofessional interactions are crucial elements contributing to childbirth satisfaction in the AMU environment.

Exploring patients' perspectives of gestational diabetes mellitus screening and counselling in Ontario: A grounded theory study.

INTRODUCTION: Gestational diabetes mellitus (GDM) is associated with adverse perinatal outcomes. Approaches to screening for GDM continue to evolve, introducing potential variability of care. This study explored the impact of these variations on GDM counselling and screening from the perspectives of pregnant individuals. METHODS: Following a Corbin and Strauss approach to qualitative, grounded theory we recruited 28 individuals from three cities in Ontario, Canada who had a singleton pregnancy under the care of either a midwife, family physician or obstetrician. Convenience and purposive sampling techniques were used. Semi-structured telephone interviews were conducted and transcribed verbatim between March and December 2020. Transcripts were analysed inductively resulting in codes, categories and themes. RESULTS: Three themes were derived from the data about GDM screening and counselling: 'informing oneself', 'deciding' and 'screening'. All participants, regardless of geographical region, or antenatal care provider, moved through these three steps during the GDM counselling and screening process. Differences in counselling approaches between pregnancy care providers were noted throughout the 'informing' and 'deciding' stages of care. Factors influencing these differences included communication, healthcare autonomy and patient motivation to engage with health services. No differences were noted within care provider groups across the three geographic regions. Participant experiences of GDM screening were influenced by logistical challenges and personal preferences towards testing. CONCLUSION: Informing oneself about GDM may be a crucial step for facilitating decision-making and screening uptake, with an emphasis on information provision to facilitate patient autonomy and motivation. PATIENT OR PUBLIC CONTRIBUTION: Participants of our study included patients and service users. Participants were actively involved in the study design due to the qualitative, patient-centred nature of the research methods employed. Analysis of results was structured according to the emergent themes of the data which were grounded in patient perspectives and experiences.

The impact of funding models on the integration of Ontario midwives: a qualitative study.

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.

Cardiovascular Outcomes During Index Hospitalization in Children with Kawasaki Disease in Ontario, Canada.

Kawasaki disease (KD) is a common childhood vasculitis associated with coronary artery aneurysms (CAA). However, there is limited published data on other cardiovascular events diagnosed during acute KD hospitalizations. Our objectives were to determine the incidence of cardiovascular events during acute KD hospitalizations, stratified by age at admission, CAA status, and pediatric intensive care unit (PICU) admission status. We identified all children (0-18 year) hospitalized with a new KD diagnosis in Ontario, between 1995 and 2018, through validated algorithms using population health administrative databases. We excluded children previously diagnosed with KD and non-Ontario residents. We evaluated for cardiovascular events that occurred during the acute KD hospitalizations, defined by administrative coding. Among 4597 children hospitalized with KD, 3307 (71.9%) were aged 0-4 years, median length of stay was 3 days (IQR 2-4), 113 children (2.5%) had PICU admissions, and 119 (2.6%) were diagnosed with CAA. During acute hospitalization, 75 children were diagnosed with myocarditis or pericarditis (1.6%), 47 with arrhythmias (1.0%), 25 with heart failure (0.5%), and ≤ 5 with acute MI (≤ 0.1%). Seven children underwent cardiovascular procedures (0.2%). Older children (10-18 years), children with CAA, and children admitted to the PICU were more likely to experience cardiovascular events, compared with children aged 0-4 years, without CAA or non-PICU admissions, respectively. The frequency of non-CAA cardiovascular events during acute KD hospitalizations did not change significantly between 1995 and 2018. During acute KD hospitalizations, older children, children with CAA, and PICU admissions are at higher risk of cardiovascular complications, justifying closer monitoring of these high-risk individuals.

Clinician responses to cannabis use during pregnancy and lactation: a systematic review and integrative mixed-methods research synthesis.

BACKGROUND: Perinatal cannabis use is increasing, and clinician counselling is an important aspect of reducing the potential harm of cannabis use during pregnancy and lactation. To understand current counselling practices, we conducted a systematic review and integrative mixed-methods synthesis to determine "how do perinatal clinicians respond to pregnant and lactating patients who use cannabis?" METHODS: We searched 6 databases up until 2021-05-31. Eligible studies described the attitudes, perceptions, or beliefs of perinatal clinician about cannabis use during pregnancy or lactation. Eligible clinicians were those whose practice particularly focusses on pregnant and postpartum patients. The search was not limited by study design, geography, or year. We used a convergent integrative analysis method to extract relevant findings for inductive analysis. RESULTS: Thirteen studies were included; describing perspectives of 1,366 clinicians in 4 countries. We found no unified approach to screening and counselling. Clinicians often cited insufficient evidence around the effects of perinatal cannabis use and lacked confidence in counselling about use. At times, this meant clinicians did not address cannabis use with patients. Most counselled for cessation and there was little recognition of the varied reasons that patients might use cannabis, and an over-reliance on counselling focussed on the legal implications of use. CONCLUSION: Current approaches to responding to cannabis use might result in inadequate counselling. Counselling may be improved through increased education and training, which would facilitate conversations to mitigate the potential harm of perinatal cannabis use while recognizing the benefits patients perceive.

Cannabis use during pregnancy and breastfeeding is common and understanding current physician counselling approaches is important to identify gaps and to make suggestions for practice. We conducted a systematic review of the literature to understand how physicians respond to pregnant or breastfeeding patients who use cannabis. We found 13 eligible articles in our review and our analysis showed that there was no common approach to screening and counselling patients. Physicians often described needing more training and education to support their confidence. Additionally, physicians often did not address the various medical reasons for which patients might use cannabis during pregnancy and breastfeeding. We suggest that counselling approaches may be improved through increased education and training. This could facilitate conversations to help mitigate the potential harm of cannabis use while recognizing the benefits patients perceive and thus establish strong patient­physician relationships.

Health care utilization and costs following Kawasaki disease.

Objectives: Kawasaki disease (KD) is a common childhood vasculitis with increasing incidence in Canada. Acute KD hospitalizations are associated with high health care costs. However, there is minimal health care utilization data following initial hospitalization. Our objective was to determine rates of health care utilization and costs following KD diagnosis. Methods: We used population-based health administrative databases to identify all children (0 to 18 years) hospitalized for KD in Ontario between 1995 and 2018. Each case was matched to 100 nonexposed comparators by age, sex, and index year. Follow-up continued until death or March 2019. Our primary outcomes were rates of hospitalization, emergency department (ED), and outpatient physician visits. Our secondary outcomes were sector-specific and total health care costs. Results: We compared 4,597 KD cases to 459,700 matched comparators. KD cases had higher rates of hospitalization (adjusted rate ratio 2.07, 95%CI 2.00 to 2.15), outpatient visits (1.30, 95%CI 1.28 to 1.33), and ED visits (1.22, 95%CI 1.18 to 1.26) throughout follow-up. Within 1 year post-discharge, 717 (15.6%) KD cases were re-hospitalized, 4,587 (99.8%) had ≥1 outpatient physician visit and 1,695 (45.5%) had ≥1 ED visit. KD cases had higher composite health care costs post-discharge (e.g., median cost within 1 year: $2466 CAD [KD cases] versus $234 [comparators]). Total health care costs for KD cases, respectively, were $13.9 million within 1 year post-discharge and $54.8 million throughout follow-up (versus $2.2 million and $23.9 million for an equivalent number of comparators). Conclusions: Following diagnosis, KD cases had higher rates of health care utilization and costs versus nonexposed children. The rising incidence and costs associated with KD could place a significant burden on health care systems.

Incidence and short-term outcomes of Kawasaki disease.

OBJECTIVE: Kawasaki disease (KD) is a childhood vasculitis with conflicting reported North American trends in incidence and patient characteristics. OBJECTIVES: (1) determine KD incidence between 1995 and 2017; (2) compare patient characteristics by era and age group; (3) determine complication and cardiovascular follow-up rates. METHODS: We used population-based health administrative data to identify children (0-18 yr) hospitalized with KD in Ontario, Canada between 1995 and 2017. We excluded children with prior KD diagnosis or incomplete records. We determined the annualized incidence and follow-up trends. RESULTS: KD was diagnosed in 4,346 children between 1995 and 2017. Annual KD incidence was 22.0 (<5 yr), 6.1 (5-9 yr), and 0.6 (10-18 yr) per 100,000 children. KD incidence increased significantly for all age groups, including from 18.4 to 25.0 cases per 100,000 children <5 yr. Ninety-day mortality occurred in ≤5 children (≤0.1%). Coronary artery aneurysm (CAA) occurred in 106 children (2.4%, 95% confidence interval 2.0-2.9) during admission and 151 (3.5%, 95% confidence interval 3.0-4.1) during 11-year median follow-up. Children 10-18 yr had longer hospitalizations (4.3 vs. 3.5 days, p = 0.003) and more CAA (7.4% vs. 3.4%, p = 0.007). By 1-year post-diagnosis, 3970 (91.3%) and 2576 (59.3%) children had echocardiography and cardiology follow-up, respectively. CONCLUSIONS: KD incidence is increasing in Ontario, with greater healthcare utilization from hospitalizations and subsequent follow-up. IMPACT: 4346 children were hospitalized for Kawasaki disease over 22 years in Ontario, and Kawasaki disease incidence increased significantly for all age groups, males and females. Older children (10-18 years) had longer hospital length of stay, more PICU admissions and more frequent coronary artery aneurysms. Nearly all children with Kawasaki disease had follow-up echocardiography within 1 year.

"It's a Little Bit Tricky": Results from the POLYamorous Childbearing and Birth Experiences Study (POLYBABES).

The number of polyamorous people in Canada is growing steadily, and many polyamorous people are of childbearing age and report living with children. Experiences of polyamorous families, particularly those related to pregnancy and childbirth, have thus far been underrepresented in the literature. The POLYamorous Childbearing and Birth Experiences Study (POLYBABES) sought to explore the pregnancy and birth experiences of polyamorous people. Having previously reported findings relating to experiences with the health system and healthcare providers, this article specifically focuses on the social aspects of polyamorous families' experiences. We explored the impact of polyamory on one's self identity, relationship structures, and experiences navigating the social world. Anyone who self-identified as polyamorous during pregnancy and birth, gave birth in Canada within 5 years, and received some prenatal care was eligible to participate in this study. Participants were recruited through social media and interviewed online or in person. Twenty-four participants were interviewed (11 birthing people and 13 of their partners). Thematic analysis was used to explore the data, and four primary themes were identified: deliberately planning families, more is more, presenting polyamory, and living in a mononormative world. Each theme was further broken down into a number of sub-themes. We also collaborated with research participants to create a glossary of terms. By exploring the pregnancy and birth experiences of polyamorous families and focusing on participant voices, this research adds to the limited research on polyamorous families and contributes to the process of breaking down stigma associated with alternative family structures. Further, by creating an accessible glossary of terms, researchers and lay persons alike have been given access to a meaningful resource.

The effect of a new maternity unit on maternal outcomes in rural Haiti: an interrupted time series study.

BACKGROUND: In Haiti where there are high rates of maternal and neonatal mortality, efforts to reduce mortality and improve maternal newborn child health (MNCH) must be tracked and monitored to measure their success. At a rural Haitian hospital, local surveillance efforts allowed for the capture of MNCH indicators. In March 2018, a new stand-alone maternity unit was opened, with increased staff, personnel, and physical space. We aimed to determine if the new maternity unit brought about improvements in maternal and neonatal outcomes. METHODS: We conducted an interrupted time series analysis using data collected between July 2016 and October 2019 including 20 months before the opening of the maternity unit and 20 months after. We examined maternal-neonatal outcomes such as physiological (vaginal) births, caesarean birth, postpartum hemorrhage (PPH), maternal deaths, stillbirths and undesirable outcomes (eclampsia, PPH, perineal laceration, postpartum infection, maternal death or stillbirth). RESULTS: Immediately after the opening of the new maternity, the number of physiological births decreased by 7.0% (ß = - 0.070; 95% CI: - 0.110 to - 0.029; p = 0.001) and there was an increase of 6.7% in caesarean births (ß = 0.067; 95% CI: 0.026 to 0.107; p = 0.002). For all undesirable outcomes, preintervention there was an increasing trend of 1.8% (ß = 0.018; 95% CI: 0.013 to 0.024; p < 0.001), an immediate 14.4% decrease after the intervention (ß = - 0.144; 95% CI: - 0.255 to - 0.033; p = 0.012), and a decreasing trend of 1.8% through the postintervention period (ß = - 0.018; 95% CI: - 0.026 to - 0.009; p < 0.001). No other significant level or trend changes were noted. CONCLUSIONS: The new maternity unit led to an upward trend in caesarean births yet an overall reduction in all undesirable maternal and neonatal outcomes. The new maternity unit at this rural Haitian hospital positively impacted and improved maternal and neonatal outcomes.

Severe maternal morbidity surveillance: Monitoring pregnant women at high risk for prolonged hospitalisation and death.

BACKGROUND: There is no international consensus on the definition and components of severe maternal morbidity (SMM). OBJECTIVES: To propose a comprehensive definition of SMM, to create an empirically justified list of SMM types and subtypes, and to use this to examine SMM in Canada. METHODS: Severe maternal morbidity was defined as a set of heterogeneous maternal conditions known to be associated with severe illness and with prolonged hospitalisation or high case fatality. Candidate SMM types/subtypes were evaluated using information on all hospital deliveries in Canada (excluding Quebec), 2006-2015. SMM rates for 2012-2016 were quantified as a composite and as SMM types/subtypes. Rate ratios and population attributable fractions (PAF) associated with overall and specific SMM types/subtypes were estimated in relation to length of hospital stay (LOS > 7 days) and case fatality. RESULTS: There were 22 799 cases of SMM subtypes (among 1 418 545 deliveries) that were associated with a prolonged LOS or high case fatality. Between 2012 and 2016, the composite SMM rate was 16.1 (95% confidence interval [CI] 15.9, 16.3) per 1000 deliveries. Severe pre-eclampsia and HELLP syndrome (514.6 per 100 000 deliveries), and severe postpartum haemorrhage (433.2 per 100 000 deliveries) were the most common SMM types, while case fatality rates among SMM subtypes were highest among women who had cardiac arrest and resuscitation (241.1 per 1000), hepatic failure (147.1 per 1000), dialysis (67.6 per 1000), and cerebrovascular accident/stroke (51.0 per 1000). The PAF for prolonged hospital stay related to SMM was 17.8% (95% CI 17.3, 18.3), while the PAF for maternal death associated with SMM was 88.0% (95% CI 74.6, 94.4). CONCLUSIONS: The proposed definition of SMM and associated list of SMM subtypes could be used for standardised SMM surveillance, with rate ratios and PAFs associated with specific SMM types/subtypes serving to inform clinical practice and public health policy.

Resident Attitudes Towards Caesarean Delivery in Canadian Obstetrics and Gynaecology Residency Programs.

OBJECTIVE: This study aimed to explore the attitudes of obstetrics and gynaecology residents in Canada towards interventions that influence caesarean section rates. The study looked at residents' attitudes towards four guidelines that support vaginal and assisted delivery (vaginal birth after caesarean section, induction of labour, operative vaginal birth, and fetal health surveillance in labour) and towards Society of Obstetricians and Gynaecologists of Canada (SOGC) guidelines in general. The study also sought to investigate whether these attitudes vary by residency training location. METHODS: An online survey of obstetrics and gynaecology residents across Canada was conducted. Residents responded to statements derived from guidelines using a five-point attitudinal scale and to an optional long-answer question about how residency has prepared them to make decisions around interventions. Descriptive summary statistics are used to present the findings (Canadian Task Force Classification III). RESULTS: A total of 27% of residents completed the survey. The majority demonstrated attitudes congruent with guidelines and favourable towards SOGC guidelines in general. Residents attitudes were least favourable towards electronic fetal monitoring, with 67.4% of responses congruent with the guideline. Attitudes were most aligned with the operative vaginal birth guideline, with 87.9% of responses congruent with the guideline. This sample was underpowered to detect statistically significant differences among residency programs, although there was some variation in attitudes across programs, with the most congruent scoring program at 81.8% congruent responses and the lowest at 66.7%. CONCLUSION: Obstetrics and gynaecology residents in Canada have favourable attitudes towards interventions that support vaginal and assisted delivery. There was variability in observed attitudes across programs, although this was not statistically significant.

Sociodemographic Characteristics and Clinical Outcomes of People Receiving Inadequate Prenatal Care: A Retrospective Cohort Study.

OBJECTIVE: This study sought to describe the incidence inadequate prenatal care (IPNC) at an urban level II hospital in Hamilton, Ontario, and to compare the characteristics and outcomes of mothers who received IPNC and their newborns with those who received adequate prenatal care (APNC). This study is the first part of a mixed-methods research program aimed at informing the development of an interdisciplinary, patient-centred, prenatal care program for people who struggle to access conventional modes of care. METHODS: This retrospective cohort study compared mothers and neonates born at St. Joseph's Health Care Hamilton in 2016 with IPNC (fewer than or equal to four antenatal visits, or first visit in third trimester) with those born with APNC (five or more prenatal visits and initial visit before the third trimester). Cases and controls matched 3:1 for age and parity were identified through a retrospective chart review. RESULTS: In total 3235 charts were reviewed, and 69 cases of IPNC were identified (2.1%). The IPNC group had lower education and higher unemployment levels, as well as higher rates of smoking and drug use. Our primary and secondary outcomes of newborn custody loss, neonatal intensive care unit admission, and neonatal length of stay were significantly higher in the IPNC group. CONCLUSION: Patients delivering with IPNC represent a high-risk group with increased rates of adverse neonatal outcomes and newborn custody loss. This quantitative study will inform future research and innovative interdisciplinary program development aimed at increasing access to prenatal care in an effort to improve maternal and neonatal outcomes.

The Polyamorous Childbearing and Birth Experiences Study (POLYBABES): a qualitative study of the health care experiences of polyamorous families during pregnancy and birth.

BACKGROUND: As many as 1 in 5 adults practise some type of consensual nonmonogamy such as polyamory; many are married, have children, or both. Polyamorous families face unique challenges when accessing care during pregnancy and birth, and qualitative descriptive studies are needed to understand their experiences and inform health care providers' practice. METHODS: Participants, who self-identified as polyamorous, had given birth in the last 5 years and received at least some prenatal care, were recruited through convenience sampling on social media. Any of the birthing individual's partners were also invited to participate. All participants completed a short demographic questionnaire and participated in a semistructured interview. Interview transcripts were coded using Braun and Clarke's iterative thematic analysis. RESULTS: A total of 24 participants, 11 who had given birth and 13 partners, were interviewed. Of those who had given birth, 5 received midwifery care only, 4 received obstetric care exclusively and 2 received shared care. Polyamorous families described sharing many common experiences during pregnancy and birth that were affected by their polyamorous identity. Although participants reported both positive and negative experiences with health care providers, when accessing health care all had experienced some form of marginalization that was related to their polyamorous status. One particular challenge for families was with respect to disclosure of polyamorous identity in hospital environments. Participants offered suggestions for improving the health care of polyamorous families during pregnancy and birth, including creating nonjudgmental spaces, accommodating difference through minimizing administrative barriers and allying with patients by providing patient-led care. INTERPRETATION: Polyamorous families face marginalization when accessing pregnancy and birth care. Care experiences for polyamorous families can be improved by nonjudgmental, open attitudes of health care providers, and modifications to hospital policies to support multiparent families.
