The effects of previous cesarean deliveries on severe maternal and adverse perinatal outcomes at a university hospital in Tanzania

Risk factors of stillbirths in four district hospitals on Pemba Island, Tanzania: a prospective cohort study

BACKGROUND

More than 2 million third-trimester stillbirths occur yearly, most of them in low- and middle-income countries. Data on stillbirths in these countries are rarely collected systematically. This study investigated the stillbirth rate and risk factors associated with stillbirth in four district hospitals in Pemba Island, Tanzania.

METHODS

A prospective cohort study was completed between the 13th of September and the 29th of November 2019. All singleton births were eligible for inclusion. Events and history during pregnancy and indicators for adherence to guidelines were analysed in a logistic regression model that identified odds ratios [OR] with a 95% confidence interval [95% CI].

RESULTS

A stillbirth rate of 22 per 1000 total births in the cohort was identified; 35.5% were intrapartum stillbirths (total number of stillbirths in the cohort, n = 31). Risk factors for stillbirth were breech or cephalic malpresentation (OR 17.67, CI 7.5-41.64), decreased or no foetal movements (OR 2.6, CI 1.13-5.98), caesarean section [CS] (OR 5.19, CI 2.32-11.62), previous CS (OR 2.63, CI 1.05-6.59), preeclampsia (OR 21.54, CI 5.28-87.8), premature rupture of membranes or rupture of membranes 18 h before birth (OR 2.5, CI 1.06-5.94) and meconium stained amniotic fluid (OR 12.03, CI 5.23-27.67). Blood pressure was not routinely measured, and 25% of women with stillbirths with no registered foetal heart rate [FHR] at admission underwent CS.

CONCLUSIONS

The stillbirth rate in this cohort was 22 per 1000 total births and did not fulfil the Every Newborn Action Plan's goal of 12 stillbirths per 1000 total births in 2030. Awareness of risk factors associated with stillbirth, preventive interventions and improved adherence to clinical guidelines during labour, and hence improved quality of care, are needed to decrease the stillbirth rate in resource-limited settings.

Correlation Between Previous Caesarean Section and Adverse Maternal Outcomes Accordingly With Robson Classification: Systematic Review and Meta-Analysis

Background: The increasing rates of Caesarean section (CS) beyond the WHO standards (10–15%) pose a significant global health concern.

Objective: Systematic review and meta-analysis to identify an association between CS history and maternal adverse outcomes for the subsequent pregnancy and delivery among women classified in Robson classification (RC).

Search Strategy: PubMed/Medline, EbscoHost, ProQuest, Embase, Web of Science, BIOSIS, MEDLINE, and Russian Science Citation Index databases were searched from 2008 to 2018.

Selection Criteria: Based on Robson classification, studies reporting one or more of the 14 adverse maternal outcomes were considered eligible for this review.

Data Collection: Study design data, interventions used, CS history, and adverse maternal outcomes were extracted.

Main Results: From 4,084 studies, 28 (n = 1,524,695 women) met the inclusion criteria. RC group 5 showed the highest proportion among deliveries followed by RC10, RC7, and RC8 (67.71, 32.27, 0.02, and 0.001%). Among adverse maternal outcomes, hysterectomy had the highest association after preterm delivery OR = 3.39 (95% CI 1.56–7.36), followed by Severe Maternal Outcomes OR = 2.95 (95% CI 1.00–8.67). We identified over one and a half million pregnant women, of whom the majority were found to belong to RC group 5.

Conclusions: Previous CS was observed to be associated with adverse maternal outcomes for the subsequent pregnancies. CS rates need to be monitored given the prospective risks which may occur for maternal and child health in subsequent births.

Analysis of the Severe Maternal Outcomes between Resource-Poor and Resource-Rich Hospitals in China’s Hunan Province from 2012 to 2018

Background. This facility-based study analyzed the epidemiology and incidence of maternal near miss (MNM) and mortality by hospital level as part of Hunan Province’s efforts to raise the quality of hospital care for women. Methods. We used data for MNM and mortality cases for 2012–2018 from 17 hospitals (12 resource-poor facilities, five resource-rich facilities) that receive referrals for obstetric complications in Hunan Province. Data were drawn from China’s National Maternal Near Miss Surveillance System and collected using the World Health Organization near miss tool. We calculated the ratio of severe maternal outcomes (SMO) (i.e., MNM and maternal death (MD) cases), mortality index (MI), and MNM to mortality ratio (MNM : MD), and epidemiological factors, organ dysfunction, and maternal complications stratified by hospital level. The chi-square tests to examine differences between groups and total ratios and 95% CI were calculated. Results. There were 518 SMO cases (489 MNM and 29 MD) among 279407 live births (LBs) and 1299 SMO cases (1262 MNM and 37 MD) among 232386 LBs in resource-poor and resource-rich facilities. The total MNM ratio in resource-poor and resource-rich hospitals was 1.75 (95% CI: 1.60–1.91) and 5.43 (95% CI: 5.14–5.74) per 1000 LBs, respectively. There were differences in SMO cases between resource-poor and resource-rich hospitals in maternal age, education, parity, antenatal visits, and history of cesarean sections. In MNM cases, coagulation dysfunction was the main organ dysfunction (resource-poor hospitals: 59.10%; resource-rich hospitals: 79.32%), and the main maternal complications were obstetric hemorrhage (resource-poor hospitals: 71.98%) and hepatopathy (resource-rich hospitals: 69.49%). For MD cases, the main maternal complications were neurologic dysfunction (resource-poor hospitals: 41.38%) and coagulation dysfunction (resource-rich hospitals: 42.55%). Anemia was the main maternal complication for SMO cases in both resource-poor (69.69%) and resource-rich (68.59%) hospitals. Conclusions. MNM and MD are higher in resource-rich hospitals compared with resource-poor hospitals. The obstetric emergency capacity of resource-rich hospitals is higher than that of resource-poor hospitals. Future government policies should consider upgrading the obstetric emergency treatment capacity in resource-poor hospitals or to redistinguish the social functions of different medical institutions.

Risk of Severe Adverse Maternal and Neonatal Outcomes in Deliveries with Repeated and Primary Cesarean Deliveries versus Vaginal Deliveries: A Cross-Sectional Study

Objective

To determine risks of severe adverse maternal and neonatal outcomes in women with repeated cesarean delivery (CD) and primary CD compared with those with vaginal delivery (VD).

Methods

Data of this cross-sectional study were extracted from 2,262 pregnant women who gave birth between August 2014 and December 2016, at Srinagarind Hospital, Khon Kaen University. Severe maternal outcomes were categorized based on the World Health Organization criteria. Adjusted odds ratio (aOR) and 95% confidence intervals (CI) were calculated to indicate the risk of severe adverse maternal and neonatal outcomes among women underwent CD compared with those who underwent VD.

Results

There were no cases of maternal death in this study. CD significantly increased risk of severe adverse maternal outcomes (SMO) (aOR 10.59; 95% CI, 1.19-94.54 for primary CD and aOR 17.21; 95% CI, 1.97-150.51 for repeated CD) compared with women who delivered vaginally. When compared with vaginal delivery, the risks of neonatal near miss (NNM) and severe adverse neonatal outcomes (SNO) were significantly higher in primary CD group (aOR 1.71; 95% CI 1.17-2.51 and aOR 1.66; 95% CI 1.14-2.43), respectively. For repeated CD, the risks were borderline significant (aOR, 1.58; 95% CI, 0.98-2.56 for NNM and aOR, 1.61; 95% CI, 0.99-2.60 for SNO).

Conclusion

Primary and repeated CD significantly increased the risk of SMO compared with VD. Risks of NNM and SNO were also significantly increased in women with primary CD. The risks of NNM and SNO for repeated CD trended toward a significant increase.

Factors associated with the timing of the first prenatal ultrasound in Canada

Background

The aim of this study was to investigate the factors associated with the timing of the first prenatal ultrasound in Canada.

Methods

This was a secondary data analysis of the Maternity Experiences Survey, a cross-sectional survey covering different aspects of pregnancy, labour, birth and the post-partum period. Bivariate and multivariate multinomial logistic regressions were performed to assess the relationship between timing of first prenatal ultrasound and different independent variables.

Results

68.4% of Canadian women received an optimally timed first prenatal ultrasound, 27.4% received early ultrasounds and 4.3% received late ultrasound. The highest prevalence of early ultrasound was in Ontario (33.3%) and the lowest was in Manitoba (13.3%). The highest prevalence of late ultrasound was found in Manitoba (12.1%) and the lowest was in British Columbia and Ontario (3.5% each). The highest prevalence of optimal timing of first prenatal ultrasound was in Quebec (77%) and the lowest was in Ontario (63.2%). Factors influencing the timing of ultrasound included: Early – maternal age < 20 (adjusted OR = 0.54, 95%CI:0.34–0.84), alcohol use during pregnancy (adjusted OR = 0.69, 95%CI:0.53–0.90), history of premature birth (adjusted OR = 1.41, 95%CI:1.06–1.89), multiparity (adjusted OR = 0.67, 95%CI:0.57–0.78), born outside of Canada (adjusted OR = 0.82, 95%CI:0.67–0.99), prenatal care in Newfoundland and Labrador (adjusted OR = 1.66, 95%CI:1.20–1.30), Nova Scotia (adjusted OR = 1.68, 95%CI:1.25–2.28), Ontario (adjusted OR = 2.16, 95%CI:1.76–2.65), Saskatchewan (adjusted OR = 1.50, 95%CI:1.05–2.14), Alberta (adjusted OR = 1.37, 95%CI:1.05–1.77) British Columbia (adjusted OR = 1.90, 95%CI:1.45–2.50) and Manitoba (adjusted OR = 0.66, 95%CI:0.45–0.98) Late – unintended pregnancy (adjusted OR = 1.89, 95%CI:1.38–2.59), born outside of Canada (adjusted OR = 1.75, 95%CI:1.14–2.68), prenatal care in Manitoba (adjusted OR = 2.88, 95%CI:1.64–5.05) and the Territories (adjusted OR = 4.50, 95%CI:2.27–8.93). An interaction between history of miscarriage and having ‘other’ prenatal care provider significantly affected timing of ultrasound (adjusted OR = 0.31, 95%CI:0.14–0.66).

Conclusion

Only 68% of Canadian women received an optimally timed prenatal ultrasound which was influenced by several factors including province of prenatal care, maternal age and country of birth, and an interaction effect between prenatal care provider and history of miscarriage. These findings establish a baseline of factors influencing the timing of prenatal ultrasound in Canada, which can be built upon by future studies.

Short-term and long-term effects of caesarean section on the health of women and children

A caesarean section (CS) can be a life-saving intervention when medically indicated, but this procedure can also lead to short-term and long-term health effects for women and children. Given the increasing use of CS, particularly without medical indication, an increased understanding of its health effects on women and children has become crucial, which we discuss in this Series paper. The prevalence of maternal mortality and maternal morbidity is higher after CS than after vaginal birth. CS is associated with an increased risk of uterine rupture, abnormal placentation, ectopic pregnancy, stillbirth, and preterm birth, and these risks increase in a dose-response manner. There is emerging evidence that babies born by CS have different hormonal, physical, bacterial, and medical exposures, and that these exposures can subtly alter neonatal physiology. Short-term risks of CS include altered immune development, an increased likelihood of allergy, atopy, and asthma, and reduced intestinal gut microbiome diversity. The persistence of these risks into later life is less well investigated, although an association between CS use and greater incidence of late childhood obesity and asthma are frequently reported. There are few studies that focus on the effects of CS on cognitive and educational outcomes. Understanding potential mechanisms that link CS with childhood outcomes, such as the role of the developing neonatal microbiome, has potential to inform novel strategies and research for optimising CS use and promote optimal physiological processes and development.

Predictors of maternal near miss among women admitted in Gurage zone hospitals, South Ethiopia, 2017: a case control study

BACKGROUND

Maternal mortality and morbidity remain unacceptably high in developing countries. Behind every maternal death, many other women suffered from acute and chronic obstetric complications. Women who survive severe acute maternal morbidities/near miss have many characteristics in common with maternal death events particularly on risk factors. Ethiopia is among countries with high maternal mortality and morbidities in sub-Saharan Africa. However there is scarce evidence on risk factors of severe acute maternal morbidities in Ethiopia. Therefore this study aimed to identify predictors of maternal near miss among women admitted in Gurage zone hospitals, south Ethiopia, 2017.

METHODS

Hospital based case control study was conducted to assess predictors of maternal near miss among women admitted in five hospitals of Gurage zone, South Ethiopia. Data of 229 (77 cases and 152 controls) women were included in the analysis. Cases were women admitted due to severe acute maternal morbidity while controls were women admitted for normal labor or women admitted due to mild to moderate obstetric complications. Cases were identified by validated-disease specific criteria. Then, two controls were selected for each verified case using lottery method among eligible women. Data were collected using interviewer administered questionnaire and reviewing patients' records. Data were entered using Epi Info 7 and analyzed by SPSS 21. Multivariable logistic regression analysis was done to identify independent predictors of maternal near miss.

RESULT

Majority of cases were admitted due to dystocia (57.1%) and obstetric hemorrhage (26%). The median first delay (delay to seek health care) among cases and controls was six and 4 h respectively. Prior history of cesarean section {AOR 7.68, 95%CI, 3.11-18.96}, first delay {AOR 2.79, 95%CI, 1.42-5.50}, and being referred from other health facilities {AOR 7.47, 95% CI, 2.27-24.51} were independent predictors of maternal near miss.

CONCLUSIONS

Prior history of cesarean section, being referred from other health facilities and first delay were factors associated with maternal near miss. Timely health care seeking behavior of women is uncommon in the study area. Therefore primary health care programs need to enhance the existing efforts to improve timely health care seeking behavior of women.

Feto-maternal Outcomes of Emergency Caesarean Section following Residential Posting at Dhading District Hospital

INTRODUCTION

Caesarean section is a commonly performed major obstetric surgery to deliver baby under certain indications which may be maternal or fetal. If performed timely, it is helpful to save the life of mother and fetus and if not, it increases both maternal and fetal risks.

METHODS

A hospital based descriptive cross-sectional study was conducted at Dhading district hospital from 17th October 2016 to 17th October 2017. Total of 41 patients undergoing emergency caesarean section meeting the selection criteria were included.

RESULTS

The incidence of emergency caesarean section was 41 (5.5%). Most common indication for caesarean delivery was fetal distress in 12 (29.3%) followed by failed induction and cephalopelvic disproportion each accounting 6 (14.6%) cases. The least common causes being chorioamnionitis and cord prolapse in 1 (2.4%). Regarding perinatal outcomes, 33 (80.5%) babies delivered were of normal weight. Low Apgar score (<7) at one minute was noted in 8 (19.5%) cases. Neonatal resuscitation in the form of oxygen supplementation was required in 2 (4.9%) cases whereas bag and mask ventilation was required in 5 (12.2%) cases. Referral for neonatal intensive care unit admission was done in 6 (14.6%) cases. There were three neonatal deaths.

CONCLUSIONS

Residential posting was fruitful to decrease feto-maternal morbidities and mortalities. Even to minimize the delay of treatment, government should provide adequate equipments and skilled man-power to run neonatal intensive care unit.

Maternal near-miss and death incidences - Frequencies, causes and the referral chain in Somaliland: A pilot study using the WHO near-miss approach

Background Somaliland is a self-declared country with a population of 3.5 million. Most of its population reside in rural areas. The objective of this pilot near-miss study was to monitor the frequency and causes of maternal near-miss and deaths and the referral chain for women to access Skilled Birth Attendants (SBA).

METHOD

A facility-based study of all maternal near-miss and mortality cases over 5months using the WHO near-miss tool in a main referral hospital. Reasons for bypassing the Antenatal Care facility (ANC) and late arrival to the referral hospital were investigated through verbal autopsy.

RESULTS

One hundred and thirty-eight (138) women with severe maternal complications were identified: 120 maternal near-miss, 18 maternal deaths. There were more near-miss cases on arrival (74.2%) compared with events that developed inside the hospital (25.8%). Likewise, there were more maternal deaths (77.8%) on arrival than was the case during hospitalization (22.2%). The most common mode of referral among maternal near-miss events was family referrals (66.7%). Of 18 maternal deaths, 15 were family referrals. Reasons for bypassing ANC were as follows: lack of confidence in the service provided; lack of financial resources; and lack of time to visit ANC. Reasons for late arrival to the referral hospital were as follows: lack of knowledge and transportation; and poor communication. Conclusion and clinical implication: To increase the utilization of ANC might indirectly lower the number of near-miss and death events. Collaboration between ANC staff and referral hospital staff and a more comprehensive near-miss project are proposed.

Factors associated with maternal near miss in childbirth and the postpartum period: findings from the birth in Brazil National Survey, 2011-2012

BACKGROUND

Maternal near-miss (MNM) audits are considered a useful approach to improving maternal healthcare. The aim of this study was to evaluate the factors associated with maternal near-miss cases in childbirth and the postpartum period in Brazil.

METHODS

The study is based on data from a nationwide hospital-based survey of 23,894 women conducted in 2011-2012. The data are from interviews with mothers during the postpartum period and from hospital medical files. Univariate and multivariable logistic regressions were performed to analyze factors associated with MNM, including estimation of crude and adjusted odds ratios and their respective 95 % confidence intervals (95 % CI).

RESULTS

The estimated incidence of MNM was 10.2/1,000 live births (95 % CI: 7.5-13.7). In the adjusted analyses, MNM was associated with the absence of antenatal care (OR: 4.65; 95 % CI: 1.51-14.31), search for two or more services before admission to delivery care (OR: 4.49; 95 % CI: 2.12-9.52), obstetric complications (OR: 9.29; 95 % CI: 6.69-12.90), and type of birth: elective C-section (OR: 2.54; 95 % CI: 1.67-3.88) and forceps (OR: 9.37; 95 % CI: 4.01-21.91). Social and demographic maternal characteristics were not associated with MNM, although women who self-reported as white and women with higher schooling had better access to antenatal and maternity care services.

CONCLUSION

The high proportion of elective C-sections performed among women in better social and economic situations in Brazil is likely attenuating the benefits that could be realized from improved prenatal care and greater access to maternity services. Strategies for reducing the rate of MNM in Brazil should focus on: 1) increasing access to prenatal care and delivery care, particularly among women who are at greater social and economic risk and 2) reducing the rate of elective cesarean section, particularly among women who receive services at private maternity facilities, where C-section rates reach 90 % of births.
