A framework for understanding how midwives perceive and provide care management for pregnancies complicated by gestational diabetes or hypertensive disorders of pregnancy.

BACKGROUND: Both gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) are common, and each are associated with adverse maternal and perinatal outcomes. Midwives may be the first point of care when these conditions arise. This study evaluated the experiences of midwives when providing care to women and people with pregnancies complicated by GDM or HDP. METHODS: A mixed methods study was completed in Ontario, Canada, using a sequential, explanatory approach. A total of 144 online surveys were completed by midwives, followed by 20 semi-structured interviews that were audio recorded and transcribed verbatim. Survey data were analysed using descriptive statistics. Thematic analysis was used to generate codes from the interview data, which were mapped to the Theoretical Domains Framework (TDF), to elucidate factors that might influence management. RESULTS: Most of the midwives' clinical behaviours relating to GDM or HDP were in keeping with guidelines and regulatory standards set by existing provincial standards. Six theoretical domains from the TDF appeared to influence midwives'care pathway: "Internal influences" included knowledge, skills and beliefs about capabilities; while "external influences" included social/professional role and identity, environmental context, and social influences. Interprofessional collaboration emerged as a significant factor on both the internal and external levels of influence. CONCLUSIONS: We identified barriers and facilitators that may improve the experiences of midwives and clients when GDM or HDP newly arises in a pregnancy, necessitating further consultation or management by another health care provider.

Midwives perceptions of managing pregnancies complicated by obesity: A mixed methods study.

OBJECTIVE: The growing prevalence of obesity is a concern for midwives. In Canada, the absence of regulatory standards, varying protocols and consultant preferences shape clinical decision making for the midwife and may lead to inconsistent practice. Our aim was to understand the barriers, enablers, and knowledge gaps that influenced experiences of midwives in Ontario, Canada when providing care to clients impacted by obesity. METHODS: Mixed methods design using a sequential, explanatory approach. Surveys conducted with midwives were administered using an online platform, followed by semi-structured interviews to understand the perspectives elicited in the survey in greater detail. Interviews were audio recorded and transcribed verbatim. Survey data were analyzed using descriptive statistics, and thematic analysis was used for generating codes, categories and themes from the interview data. RESULTS: 144 midwives completed the survey and 20 participated in an interview. The participants described their clinical management when caring for those with obesity which included considerations regarding additional tests/investigations, consultation and transfer of care, and place of birth. Up to 93% of surveyed midwives believed that clients with obesity were appropriate for midwifery-led care however there was less certainty about suitability as BMI increased to higher ranges such as > 45). The care management was influenced by beliefs and attitudes, knowledge, and system-level factors. Midwives experienced barriers such as inconsistent practices and role confusion, and felt ill equipped to care for pregnancies affected by obesity due to unclear guidelines. CONCLUSIONS: Overall, midwives believe clients with obesity are suitable for midwifery-led care due to its individualized, non-judgmental approach to care. Additional training for midwives and other obstetric care providers would be beneficial to help overcome barriers in providing effective care to pregnancies affected by obesity.

A clinical carepath for obese pregnant women: a pragmatic pilot cluster randomized controlled trial.

Objectives: Obese women are at increased risks for complications during pregnancy, birth, and in their infants. Although guidelines have been established for the clinical care of obese pregnant women, management is sometimes suboptimal. Our goal was to determine the feasibility of implementing and testing a clinical carepath for obese pregnant women compared to standard care, in a pilot cluster randomized controlled trial (RCT). Methods: A pragmatic pilot cluster RCT was conducted, randomly allocating eight clinics to the carepath or standard care for obese pregnant women. Women were eligible if they had a pre-pregnancy body mass index (BMI) of ≥30 kg/m2 and a viable singleton <21 weeks. The primary outcomes were the feasibility of conducting a full-scale cluster RCT (defined as >80%: randomization of clinics, use in eligible women, and completeness of follow-up) and of the intervention (defined as >80%: compliance with each step in the carepath and recommendation of the carepath by clinicians to a colleague). Results: All eight approached clinics agreed to participate and were randomized. Half of the intervention clinics used the carepath, resulting in <80% uptake of eligible women. High follow-up (99.5%) was achieved, in 188 of 189 women. The carepath was feasible for numerous guideline-directed recommendations for screening, but less so for counseling topics. When the carepath was used in the majority of women, all clinicians, most of whom were midwives, reported they would recommend it to a colleague. The intervention group had significantly higher overall adherence to the guideline recommendations compared to control (relative risk: 1.71, 95% confidence interval: 1.57-1.87). Conclusions: In this pragmatic pilot cluster RCT, a guideline-directed clinical carepath improved some aspects of care of obese pregnant women and was recommended by clinicians, particularly midwives. A cluster RCT may not be feasible in a mix of obstetric and midwifery clinics, but may be feasible in midwifery clinics.

Women's values and preferences for thromboprophylaxis during pregnancy: a comparison of direct-choice and decision analysis using patient specific utilities.

BACKGROUND: Women with a history of venous thromboembolism (VTE) have an increased recurrence risk during pregnancy. Low molecular weight heparin (LMWH) reduces this risk, but is costly, burdensome, and may increase risk of bleeding. The decision to start thromboprophylaxis during pregnancy is sensitive to women's values and preferences. Our objective was to compare women's choices using a holistic approach in which they were presented all of the relevant information (direct-choice) versus a personalized decision analysis in which a mathematical model incorporated their preferences and VTE risk to make a treatment recommendation. METHODS: Multicenter, international study. Structured interviews were on women with a history of VTE who were pregnant, planning, or considering pregnancy. Women indicated their willingness to receive thromboprophylaxis based on scenarios using personalized estimates of VTE recurrence and bleeding risks. We also obtained women's values for health outcomes using a visual analog scale. We performed individualized decision analyses for each participant and compared model recommendations to decisions made when presented with the direct-choice exercise. RESULTS: Of the 123 women in the study, the decision model recommended LMWH for 51 women and recommended against LMWH for 72 women. 12% (6/51) of women for whom the decision model recommended thromboprophylaxis chose not to take LMWH; 72% (52/72) of women for whom the decision model recommended against thromboprophylaxis chose LMWH. CONCLUSIONS: We observed a high degree of discordance between decisions in the direct-choice exercise and decision model recommendations. Although which approach best captures individuals' true values remains uncertain, personalized decision support tools presenting results based on personalized risks and values may improve decision making.

A qualitative descriptive study of the group prenatal care experience: perceptions of women with low-risk pregnancies and their midwives.

BACKGROUND: Group prenatal care (GPC) originated in 1994 as an innovative model of prenatal care delivery. In GPC, eight to twelve pregnant women of similar gestational age meet with a health care provider to receive their prenatal check-up and education in a group setting. GPC offers significant health benefits in comparison to traditional, one-on-one prenatal care. Women in GPC actively engage in their healthcare and experience a supportive network with one another. The purpose of this study was to better understand the GPC experience of women and care providers in a lower risk group of women than often has been previously studied. METHODS: This qualitative descriptive study collected data through three focus group interviews--two with women who had completed GPC at a midwifery clinic in Ontario, Canada and one with the midwives at the clinic. Data was analyzed through open coding to identify themes. RESULTS: Nine women and five midwives participated in the focus groups, from which eight categories as well as further subcategories were identified: The women and midwives noted reasons for participating (connections, education, efficiency). Participants suggested both benefits (learning from the group, normalizing the pregnancy experience, preparedness for labour and delivery, and improved relationships as all contributing to positive health outcomes) and concerns with GPC (e.g. sufficient time with the midwife) which generally diminished with experience. Suggestions for change focused on content, environment, partners, and access to the midwives. Challenges to providing GPC included scheduling and systems-level issues such as funding and regulation. Flexibility and commitment to the model facilitated it. Comparison with other models of care identified less of a relationship with the midwife, but more information received. In promoting GPC, women would emphasize the philosophy of care to other women and the midwives would promote the reduction in workload and women's independence to colleagues. CONCLUSIONS: Overall, women and midwives expressed a high level of satisfaction with their GPC experience. This study gained insight into previously unexplored areas of the GPC experience, perceptions of processes that contribute to positive health outcomes, strategies to promote GPC and elements that enhance the feasibility of GPC.

Comparison of midwifery, family medicine, and obstetric patients' understanding of weight gain during pregnancy: a minority of women report correct counselling.

OBJECTIVE: We hypothesized that differences in models of care between health care providers would result in variations in patients' reports of counselling. Our objective was to compare what women reported being advised about weight gain during pregnancy and the risks of inappropriate weight gain according to their type of health care provider. METHODS: A cross-sectional survey was conducted using a self-administered questionnaire at obstetric, midwifery, and family medicine clinics in Hamilton, Ontario. Women were eligible to participate if they had had at least one prenatal visit, could read English, and had a live, singleton pregnancy. RESULTS: Three hundred and eight women completed the survey, a 93% response rate. Care for 90% of the group was divided approximately evenly between midwives, family physicians, and obstetricians. A minority of women looked after by any of the types of care providers reported being counselled correctly about how much weight to gain during pregnancy (16.3%, 10.3%, 9.2%, and 5.7% of patients of midwives, family physicians, obstetricians, or other types of care providers, respectively, P = 0.349). A minority of women with any category of care provider was planning to gain an amount of weight that fell within the guidelines or reported being told that there were risks to themselves or their babies with inappropriate gain. CONCLUSION: In this study comparing reported counselling between patients of obstetricians, midwives, family physicians, and other health care providers, low rates of counselling about gestational weight gain were universally reported. There is a common need for more effective counselling.

A survey of preconceptional folic acid use in a group of Canadian women.

BACKGROUND: Randomized controlled trials have demonstrated that periconceptional folic acid supplementation has a dramatic effect in reducing neural tube defects, one of the most serious congenital anomalies. Unfortunately, supplementation tends to be suboptimal in disadvantaged populations. OBJECTIVE: The primary objective was to determine patient factors associated with a lack of use of periconceptional folic acid among Canadian women in a multi-ethnic, urban setting. Our secondary objective was to assess patient knowledge about folic acid tablet supplementation and its link to reduced birth defects. METHODS: We undertook a cross-sectional study to survey postpartum Toronto women on their use and knowledge of periconceptional folic acid. RESULTS: Of the 383 women surveyed, only 28% took folic acid or a multivitamin containing folic acid during the periconceptional period. Multivariate analysis revealed that the use of periconceptional folic acid was more common among women of Jewish descent (adjusted relative risk [RR] 0.3; 95% confidence interval [CI], 0.04-0.9) and those who had 1 or no children (adjusted RR 0.6; 95% CI, 0.4-0.8). Not taking folic acid was associated with unplanned pregnancy (adjusted RR 1.5; 95% CI, 1.4-1.6) and a lack of knowledge about when folic acid should be taken (adjusted RR 1.8; 95% CI, 1.6-1.8). CONCLUSION: Ethnic background is an independent predictor of periconceptional folic acid use.

The prevention of congenital anomalies with periconceptional folic acid supplementation.

Large randomized trials have demonstrated the critical role of folic acid supplementation in the prevention of neural tube defects. Since 1992, a number of national and international professional societies have released guidelines recommending folic acid supplementation of at least 0.4 mg/day for all women of childbearing age or women planning pregnancies, and 4 mg/day for women with a previous infant with a neural tube defect. Furthermore, a reduction in the incidence of congenital cardiac and urologic anomalies has been demonstrated in some studies following periconceptional folic acid supplementation. There is growing evidence of a possible role of folic acid supplementation in the prevention of other congenital anomalies, including cardiac defects. Since 1998, mandatory fortification of certain foods with folate has been associated with at least a 54% reduction in the incidence of open neural tube defects, yet rates of periconceptional folic acid use remain suboptimal, especially in minority women. Innovative strategies in educating women, health-care providers, and pharmacists on the benefits of folic acid supplementation need to be explored. Mandatory folate fortification of foods needs to be defined and monitored.
