A retrospective cohort study of the association between midwifery experience and perinatal mortality

He Korowai Manaaki (Pregnancy Wraparound Care): Protocol for a Cluster Randomized Clinical Trial

Background

Maternal and infant health inequities between Māori (the Indigenous peoples of Aotearoa New Zealand) and New Zealand European women are well documented and cannot be explained solely by socioeconomic status. A research center-iwi (tribal group) partnership aims to address these disparities and improve maternal and infant health outcomes by implementing an augmented maternity care pathway (He Korowai Manaaki) to improve access to services and evidence-informed care.

Objective

The objective of this study is to test whether an augmented maternity care pathway improves Māori infant health outcomes.

Methods

This is a Kaupapa Māori (by, with, and for Māori) cluster randomized clinical trial involving 8 primary care practices allocated to either an intervention arm or control arm. The intervention arm comprises an augmented maternity care pathway (He Korowai Manaaki) offering clinical care through additional paid health care appointments and improved access to social support (eg, housing, transport). The control arm is usual care. The primary outcome is increased timely vaccination for Māori infants, defined as all age-appropriate vaccinations completed by 6 months of age.

Results

Recruitment commenced in November 2018 and was completed in June 2020, with 251 enrolled women recruited in intervention primary care practices before 20 weeks of pregnancy. Publication of results is anticipated in late 2023.

Conclusions

The results will inform primary health care policy including whether the provision of augmented maternal care pathways reduces disparities in the structural determinants of health. If effective, He Korowai Manaaki will strengthen the health and well-being of pregnant Māori women and their babies and improve their health outcomes, laying a strong foundation for lifelong health and well-being.

Maternal and health service predictors of postpartum hemorrhage across 14 district, general and regional hospitals in Thailand

Background

Postpartum hemorrhage (PPH) is a preventable complication, however, it remains being the leading cause of maternal mortality and morbidity worldwide including Thailand.

Methods

A case-control study to examine the risk factors associated with PPH across the hospitals under the Ministry of Public Health in Thailand, was conducted. A total of 1833 patient birth records and hospital profiles including human and physical resources from 14 hospitals were obtained. A multiple logistic regression was used identifing the factors that are significantly associated with PPH.

Results

The results show that the rate of PPH varied across the hospitals ranging from 1.4 to 10.6%. Women with past history of PPH were more likely to have increased risk of having PPH by 10.97 times (95% CI 2.27,53.05) compared to those who did not. The odds of PPH was higher in district and general hospitals by 14 (95% CI 3.95,50.04) and 7 (95% CI 2.27,23.27) times respectively, compared to regional hospitals. The hospitals which had inadequate nurse midwife to patient ratio (OR 2.31,95% CI 1.08,4.92), lacked nurse midwives with working experience of 6–10 years (OR 2.35, 95% CI 1.41,3.92), as well as inadequate equipment and supplies for emergency obstetric care (OR 6.47, 95% CI 1.93,21.63), had significantly higher incidence of having PPH, respectively.

Conclusions

This study provides interesting information that the rate of PPH varies across the hospitals in Thailand, in particular where essential nurse midwives, equipment, and supplies are limited. Therefore, improving health care services by allocating sufficient human and physical resources would contribute to significantly reduce this complication.

New Zealand health system: universalism struggles with persisting inequities

New Zealand was one of the first countries to establish a universal, tax-funded national health service. Unique features include innovative Māori services, the no-fault accident compensation scheme, and the Pharmaceutical Management Agency, which negotiates with pharmaceutical companies to get the best value for medicines purchased by public money. The so-called universal orientation of the health system, along with a strong commitment to social service provision, have contributed to New Zealand's favourable health statistics. However, despite a long-standing commitment to reducing health inequities, problems with access to care persist and the system is not delivering the promise of equitable health outcomes for all population groups. Primary health services and hospital-based services have developed largely independently, and major restructuring during the 1990s did not produce the expected efficiency gains. A focus on individual-level secondary services and performance targets has been prioritised over tackling issues such as suicide, obesity, and poverty-related diseases through community-based health promotion, preventive activities, and primary care. Future changes need to focus on strengthening the culture and capacity of the system to improve equity of outcomes, including expanding Māori health service provision, integrating existing services and structures with new ones, aligning resources with need to achieve pro-equity outcomes, and strengthening population-based approaches to tackling contemporary drivers of health status.

Risk of perinatal mortality in the first year of midwifery practice in New Zealand: analysis of a retrospective national cohort

OBJECTIVES

To determine whether there was an increased risk of perinatal mortality among mothers booked for care with community lead maternity carer (LMC) midwives in their first compared with later years of practice.

DESIGN

Retrospective cohort study using linked national maternity, mortality and workforce data; adjusted analysis using logistic regression.

SETTING

New Zealand.

PARTICIPANTS

Women under community LMC midwifery care birthing 2008-2014.

MAIN OUTCOME MEASURES

Perinatal mortality (stillbirths and neonatal deaths of babies born from 20 weeks' gestation to the 27th day of postnatal life), excluding terminations and deaths associated with congenital abnormalities.

RESULTS

There were 2045 deaths among 344 910 births booked with midwives.First year of practice midwives cared for women with higher risk of perinatal mortality, including Māori, Pacific, Indian, <20-year-old mothers, nullipara, smokers, women living in socioeconomic deprivation and with high body mass index, than midwives beyond first year of practice.There was a significant reduction in unadjusted odds of perinatal mortality among women under the care of midwives beyond the first year compared with those within the first year (OR 0.79, 95% CI 0.67 to 0.93) but no significant reduction in risk remained after adjusting for known risk factors, (OR 0.89, 95% CI 0.74 to 1.07).There was a significant increase in the adjusted odds of perinatal mortality among midwives booking a caseload of 15 or fewer mothers per year (1.34, 1.01 to 1.78) and 16 to 30 (1.25, 1.04 to 1.50) compared with midwives booking 51 to 80.

CONCLUSIONS

Findings suggest that the first year of midwifery practice is not associated with an increased risk of perinatal mortality but there is evidence that early career midwives are caring for higher-risk women. These findings suggest inequity of access for higher-risk women to experienced midwives and highlight an opportunity to improve support for vulnerable women and new midwives.
