An observational study of associations among maternal fluids during parturition, neonatal output, and breastfed newborn weight loss

BackgroundNewborn weight measurements are used as a key indicator of breastfeeding adequacy. The purpose of this study was to explore non-feeding factors that might be related to newborn weight loss. The relationship between the intravenous fluids women receive during parturition (the act of giving birth, including time in labour or prior to a caesarean section) and their newborns weight loss during the first 72 hours postpartum was the primary interest.MethodsIn this observational cohort study, we collected data about maternal oral and IV fluids during labour or before a caesarean section. Participants (n = 109) weighed their newborns every 12 hours for the first three days then daily to Day 14, and they weighed neonatal output (voids and stools) for three days.ResultsAt 60 hours (nadir), mean newborn weight loss was 6.57% (SD 2.51; n = 96, range 1.83-13.06%). When groups, based on maternal fluids, were compared (≤1200 mls [n = 21] versus > 1200 [n = 53]), newborns lost 5.51% versus 6.93% (p = 0.03), respectively. For the first 24 hours, bivariate analyses show positive relationships between a) neonatal output and percentage of newborn weight lost (r(96) = 0.493, p < 0.001); and b) maternal IV fluids (final 2 hours) and neonatal output (r(42) = 0.383, p = 0.012). At 72 hours, there was a positive correlation between grams of weight lost and all maternal fluids (r(75) = 0.309, p = 0.007).ConclusionsTiming and amounts of maternal IV fluids appear correlated to neonatal output and newborn weight loss. Neonates appear to experience diuresis and correct their fluid status in the first 24 hours. We recommend a measurement at 24 hours, instead of birth weight, for baseline when assessing weight change. Because practices can differ between maternity settings, we further suggest that clinicians should collect and analyze data from dyads in their care to determine an optimal baseline measurement.

Multidisciplinary Collaborative Maternity Care in Canada: Easier Said Than Done

OBJECTIVE To describe care provider attitudes towards multidisciplinary collaborative maternity care in Canada and the factors influencing such care from the perspective of members of national professional associations of care providers. METHODS A qualitative descriptive approach was used. Leaders of national associations nominated key members, who were invited to participate in semi-structured telephone interviews. RESULTS Twenty-five participants from six national care provider associations (family physicians, obstetricians, registered midwives, registered nurses, nurse practitioners, and rural physicians) were interviewed. Participants described at least one of two main benefits of collaborative maternity care: a partial solution to the human resources shortage in maternity care, and improved maternity care for women. Despite their belief that collaboration is needed, participants expressed concern about the effects of collaboration on their practice. In particular, some participants were concerned about how collaborative models could support woman-centred care or respond to local community needs and promote continuity of care. Significant barriers to collaboration include structural factors (fee structure, liability issues) and interdisciplinary rivalry between groups of providers (turf protection, lack of mutual respect). Strategies to promote collaboration that were supported by the participants include strong national leadership and interdisciplinary education. CONCLUSION Representatives of professional associations of care providers believe that multidisciplinary collaborative maternity care is needed to sustain the availability of care providers and to improve access and womens choices for maternity care in Canada. However, they perceive that strong leadership and education are needed to address significant structural and relational barriers to collaborative practice.

A Qualitative Study of Family Involvement in Decisions About Life Support in the Intensive Care Unit

We explored family involvement in decisions about life support interventions in the intensive care unit study using a critical incident technique to focus on specific case exemplars contributed by participants. A total of 6 family members and 9 health care professionals were interviewed. Participants described 2 options (life support or comfort care) and values associated with options: maintaining quality of life, surviving critical illness, minimizing pain and suffering, not being attached to machines, needing adjustment time, and judicious health care resource use. Barriers to involvement included not being offered alternative options; no specific trigger to initiate decision making; dominant influence of professionals’ values; and families lacking understandable information. Family members are unlikely to engage in decision making unless professionals identify the decision and address other barriers to family involvement.

Women’s perspectives of the fetal fibronectin testing process: a qualitative descriptive study

BackgroundIn 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.MethodsA descriptive qualitative design was used, employing semi-structured telephone and face-to-face interviews with women who had fetal fibronectin testing.ResultsFive 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.ConclusionFetal fibronectin testing was acceptable and beneficial to these women with symptoms of preterm labour. Implications for practice and future research are suggested.

Factors Influencing the Breastfeeding Practices of Young Mothers Living in a Maternity Shelter: A Qualitative Study:

Background: Young mothers have the lowest breastfeeding rates in Canada. Young mothers and their infants who access maternity shelters are especially at risk for poor outcomes, some of which breastfeeding may help to mitigate, yet little is known of the breastfeeding practices of this population. Research aim: The purpose of this study was to answer the research question, “What factors influence the breastfeeding practices of young mothers who live or have lived in a maternity shelter?” Methods: The study was conducted using interpretive description methodology and inductive content analysis. Data were collected by means of one-on-one interviews, with the participants recruited from a maternity shelter in Ontario, Canada. Results: Nine young mothers ages 17 to 24 years, who had initiated breastfeeding and resided at a maternity shelter, were interviewed. The five themes that emerged from the data were as follows: (a) choice, (b) special, (c) importance of early postpartum support, (d) being part of the “in crowd,” and (e) importance of ongoing supports. The participants in this study took ownership of their choice to breastfeed. Hospital postpartum nurses and lactation consultants had a critical role in the establishment of early breastfeeding, and ongoing, accessible, and nonjudgmental peer, family, and community support were important to breastfeeding duration. Conclusion: A combination of emotional and practical supports from multiple trusted sources, including professional and peer supports on an ongoing basis, enabled young mothers to reach their breastfeeding goals.

A mixed methods evaluation of the maternal-newborn dashboard in Ontario: dashboard attributes, contextual factors, and facilitators and barriers to use: a study protocol

BackgroundThere are wide variations in maternal-newborn care practices and outcomes across Ontario. To help institutions and care providers learn about their own performance, the Better Outcomes Registry & Network (BORN) Ontario has implemented an audit and feedback system, the Maternal-Newborn Dashboard (MND), for all hospitals providing maternal-newborn care. The dashboard provides (1) near real-time feedback, with site-specific and peer comparison data about six key performance indicators; (2) a visual display of evidence-practice gaps related to the indicators; and (3) benchmarks to provide direction for practice change. This study aims to evaluate the effects of the dashboard, dashboard attributes, contextual factors, and facilitation/support needs that influence the use of this audit and feedback system to improve performance. The objectives of this study are to (1) evaluate the effect of implementing the dashboard across Ontario; (2) explore factors that potentially explain differences in the use of the MND among hospitals; (3) measure factors potentially associated with differential effectiveness of the MND; and (4) identify factors that predict differences in hospital performance.Methods/designA mixed methods design includes (1) an interrupted time series analysis to evaluate the effect of the intervention on six indicators, (2) key informant interviews with a purposeful sample of directors/managers from up to 20 maternal-newborn care hospitals to explore factors that influence the use of the dashboard, (3) a provincial survey of obstetrical directors/managers from all maternal-newborn hospitals in the province to measure factors that influence the use of the dashboard, and (4) a multivariable generalized linear mixed effects regression analysis of the indicators at each hospital to quantitatively evaluate the change in practice following implementation of the dashboard and to identify factors most predictive of use.DiscussionStudy results will provide essential data to develop knowledge translation strategies for facilitating practice change, which can be further evaluated through a future cluster randomized trial.

Evaluation of the impact of fetal fibronectin test implementation on hospital admissions for preterm labour in Ontario: a multiple baseline time‐series design

To determine the impact of a health system‐wide fetal fibronectin (fFN) testing programme on the rates of hospital admission for preterm labour (PTL).

Effect of a population-level performance dashboard intervention on maternal-newborn outcomes: an interrupted time series study

Objectives To assess the effect of the Maternal Newborn Dashboard on six key clinical performance indicators in the province of Ontario, Canada. Design Interrupted time series using population-based data from the provincial birth registry covering a 3-year period before implementation of the Dashboard and 2.5 years after implementation (November 2009 through March 2015). Setting All hospitals in the province of Ontario providing maternal-newborn care (n=94). Intervention A hospital-based online audit and feedback programme. Main outcome measures Rates of the six performance indicators included in the Dashboard. Results 2.5 years after implementation, the audit and feedback programme was associated with statistically significant absolute decreases in the rates of episiotomy (decrease of 1.5 per 100 women, 95% CI 0.64 to 2.39), induction for postdates in women who were less than 41 weeks at delivery (decrease of 11.7 per 100 women, 95% CI 7.4 to 16.0), repeat caesarean delivery in low-risk women performed before 39 weeks (decrease of 10.4 per 100 women, 95% CI 9.3 to 11.5) and an absolute increase in the rate of appropriately timed group B streptococcus screening (increase of 2.8 per 100, 95% CI 2.2 to 3.5). The audit and feedback programme did not significantly affect the rates of unsatisfactory newborn screening blood samples or formula supplementation at discharge. No statistically significant effects were observed for the two internal control outcomes or the four external control indicators—in fact, two external control indicators (episiotomy and postdates induction) worsened relative to before implementation. Conclusion An electronic audit and feedback programme implemented in maternal-newborn hospitals was associated with clinically relevant practice improvements at the provincial level in the majority of targeted indicators.

Young Women’s Experiences of Expected Health Behaviors During Pregnancy: The Importance of Emotional Support

Young women often have access to fewer resources to make expected behavior changes during pregnancy. This qualitative study aimed to explore the experiences of young pregnant and parenting women regarding behavioral expectations and behavior change during pregnancy. Nine women (aged 15 to 24) participated in individual semistructured photo-elicitation interviews and data was analyzed using qualitative content analysis. The findings of this study suggest that although these young women received informational support throughout their pregnancies, there is a need to integrate emotional support into prenatal care for young pregnant women to facilitate their experience as one of empowerment rather than oppression.

The Integration of Ontario Birth Centers into Existing Maternal-Newborn Services: Health Care Provider Experiences

Introduction In 2014, 2 freestanding, midwifery‐led birth centers opened in Ontario, Canada. The purpose of this study was to qualitatively investigate the integration of the birth centers into the local, preexisting intrapartum systems from the perspective of health care providers and managerial staff. Methods Focus groups or interviews were conducted with health care providers (paramedics, midwives, nurses, physicians) and managerial staff who had experienced urgent and/or nonurgent maternal or newborn transports from a birth center to one of 4 hospitals in Ottawa or Toronto. A descriptive qualitative approach to data analysis was undertaken. Results Twenty‐four health care providers and managerial staff participated in a focus group or interview. Participants described positive experiences transporting women and/or newborns from the birth centers to hospitals; these positive experiences were attributed to the collaborative planning, training, and communication that occurred prior to opening the birth centers. The degree of integration was dependent on hospital‐specific characteristics such as history, culture, and the presence or absence of midwifery privileging. Participants described the need for only minor improvements to administrative processes as well as the challenge of keeping large numbers of staff updated with respect to urgent transport policies. Planning and opening of the birth centers was seen as a driving force in further integrating midwifery care and improving interprofessional practice. Discussion The collaborative approach for the planning and implementation of the birth centers was a key factor in the successful integration into the existing maternal‐newborn system and contributed to improving integrated professional practice among midwives, paramedics, nurses, and physicians. This approach may be used as a template for the integration of other new independent health care facilities and programs into the existing health care system.
