Determinants of Uterine Rupture and Its Management Outcomes among Mothers Who Gave Birth at Public Hospitals of Tigrai, North Ethiopia: An Unmatched Case Control Study

Risk factors for maternal complications following uterine rupture: a 12-year single-center experience

PURPOSE

To determine maternal outcomes and risk factors for composite maternal morbidity following uterine rupture during pregnancy.

METHODS

A retrospective cohort study including all women diagnosed with uterine rupture during pregnancy, between 2011 and 2023, at a single-center. Patients with partial uterine rupture or dehiscence were excluded. We compared women who had composite maternal morbidity following uterine rupture to those without. Composite maternal morbidity was defined as any of the following: maternal death; hysterectomy; severe postpartum hemorrhage; disseminated intravascular coagulation; injury to adjacent organs; admission to the intensive care unit; or the need for relaparotomy. The primary outcome was risk factors associated with composite maternal morbidity following uterine rupture. The secondary outcome was the incidence of maternal and neonatal complications following uterine rupture.

RESULTS

During the study period, 147,037 women delivered. Of them, 120 were diagnosed with uterine rupture. Among these, 44 (36.7%) had composite maternal morbidity. There were no cases of maternal death and two cases of neonatal death (1.7%); packed cell transfusion was the major contributor to maternal morbidity [occurring in 36 patients (30%)]. Patients with composite maternal morbidity, compared to those without, were characterized by: increased maternal age (34.7 vs. 32.8 years, p = 0.03); lower gestational age at delivery (35 + 5 vs. 38 + 1 weeks, p = 0.01); a higher rate of unscarred uteri (22.7% vs. 2.6%, p < 0.01); and rupture occurring outside the lower uterine segment (52.3% vs. 10.5%, p < 0.01).

CONCLUSION

Uterine rupture entails increased risk for several adverse maternal outcomes, though possibly more favorable than previously described. Numerous risk factors for composite maternal morbidity following rupture exist and should be carefully assessed in these patients.

Survival Status and Predictors of Mortality Among Women with Uterine Rupture at Public Hospitals of Eastern Ethiopia. Semi-Parametric Survival Analysis

Background

Uterine rupture is the most dangerous complication of labor and contributes to high maternal mortality. Despite efforts to improve basic and comprehensive emergency obstetric treatment, women continue to suffer from disastrous maternal outcomes.

Purpose

This study aimed to assess the survival status and predictors of mortality among women with uterine rupture at public hospitals in the Harari Region, Eastern Ethiopia.

Patients and Methods

We conducted a retrospective cohort study among women with uterine rupture in public hospitals in Eastern Ethiopia. All women with uterine rupture were followed for 11 years retrospectively. Statistical analysis was conducted with STATA version 14.2. Kaplan-Meier curves together with a Log rank test were used to estimate the survival time and show the presence of differences among groups. Cox Proportion Hazard (CPH) model was used to determine the association between independent variables and survival status.

Results

There were 57,006 deliveries in the study period. We found that 10.5% (95% CI: 6.8-15.7) of women with uterine rupture have died. The median recovery and death time for women with uterine rupture were 8 and 3 days with interquartile range (IQR) of 7-11 days and 2-5 days, respectively. Antenatal care follow-up (AHR: 4.2, 95% CI: 1.8-9.79), education status (AHR: 0.11; 95% CI: 0.02-0.85), visiting health center (AHR: 4.89; 95% CI: 1.05-22.88), and admission time (AHR: 4.4; 95% CI: 1.89-10.18) were the predictors of survival status of women with uterine rupture.

Conclusion

One out of ten study participants died due to uterine rupture. Factors including not having ANC follow-up, visiting health centers for treatment, and being admitted during the night time were predictors. Thus, a great emphasis has to be given to the prevention of uterine rupture and the linkage within health institutions has to be smooth to improve the survival of patients with uterine rupture with the help of different professionals, health institutions, health bureaus, and policymakers.

Effect of optimal antenatal care on maternal and perinatal health in Ethiopia

INTRODUCTION

Receiving at least four antenatal care (ANC) visits have paramount importance on the health of mothers and perinates. In Ethiopia, several studies were conducted on ANC service utilization; however, limited studies quantified the effect of care on maternal and perinate health. In response to this gap, this study is conducted to quantify the effect of optimal ANC care (≥4 visits) on maternal and perinatal health among women who received optimal care in comparison to women who did not receive optimal care.

METHODS

The study utilized the Ethiopian perinatal death surveillance and response (PDSR) system dataset. A total of 3,814 reviewed perinatal deaths were included in the study. Considering the nature of the data, preferential within propensity score matching (PWPSM) was performed to determine the effect of optimal ANC care on maternal and perinatal health. The effect of optimal care was reported using average treatment effects of the treated [ATT].

RESULT

The result revealed that optimal ANC care had a positive effect on reducing perinatal death, due to respiratory and cardiovascular disorders, [ATT = -0.015, 95%CI (-0.029 to -0.001)] and extending intrauterine life by one week [ATT = 1.277, 95%CI: (0.563-1.991)]. While it's effect on maternal health includes, avoiding the risk of having uterine rupture [ATT = -0.012, 95%CI: (-0.018 to -0.005)], improving the utilization of operative vaginal delivery (OVD) [ATT = 0.032, 95%CI: (0.001-0.062)] and avoiding delay to decide to seek care [ATT = -0.187, 95%CI: (-0.354 to -0.021)].

CONCLUSION

Obtaining optimal ANC care has a positive effect on both maternal and perinatal health. Therefore, policies and interventions geared towards improving the coverage and quality of ANC services should be the top priority to maximize the benefit of the care.

Health Care Workers' Experiences, Challenges of Obstetric Referral Processes and Self-Reported Solutions in South Western Uganda: Mixed Methods Study

Introduction

In resource limited settings, the highest burden of adverse maternal-fetal outcomes at referral hospitals is registered from emergency obstetric referrals from lower health facilities. Implementation of referral protocols has not been optimally successful possibly attributed to lack of understanding of profile of obstetric referrals and local challenges faced during implementation process.

Objective

This study described the profile of emergency obstetric referrals, challenges faced in implementation of obstetric referral processes and explored self-reported solutions by health workers.

Methods

This was a mixed methods study done at Mbarara Regional Referral Hospital (MRRH) and health centre IVs in South-Western Uganda. We consecutively recruited emergency obstetric referrals from Isingiro district for delivery at MRRH. Using a pre-tested questionnaire, we collected demographics, obstetric and referral characteristics. We described the profile of referrals using frequencies and proportions based on demographics, obstetric and referral characteristics. We conducted focus group discussions and in-depth interviews with health workers using discussion/interview guides. Using thematic analysis, we ascertained the challenges and health worker self-reported solutions.

Results

We recruited 161 referrals: 104(65%) were below 26 years, 16(10%) had no formal education, 11(7%) reported no income, 151(94%) had no professional-escort, 137(85%) used taxis, 151(96%) were referred by midwives. Common diagnoses were previous cesarean scar (24% [n=39]) and prolonged labour (21% [n=33]). There was no communication prior to referral and no feedback from MRRH to lower health facilities. Other challenges included inconsistencies of ambulance and anesthesia services, electric power, medical supplies, support supervision, and harassment by colleagues. Self-reported solutions included the use of phone call technology for communication, audit meetings, support supervision and increasing staffing level.

Conclusion

Most referrals are of poor social-economic status, use taxis, and lack professional-escort. Health workers suffer harassment, lack of communication and shortage of supplies. We need to experiment whether mobile phone technology could solve the communication gap.

Obstructed labor and its effect on adverse maternal and fetal outcomes in Ethiopia: A systematic review and meta-analysis

Background

Obstructed labor is one of the five major causes of maternal mortality and morbidity in developing countries. In Ethiopia, it accounts for 19.1% of maternal death. The current review aimed to assess maternal and perinatal outcomes of obstructed labor in Ethiopia.

Methods

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed for this systematic review and meta-analysis. A literature search was made using PubMed/MEDLINE, CINAHL, Summon country-specific search, and Cochrane Libraries’ online databases. Search terms were adverse outcome, obstructed labor, maternal outcome, fetal outcome, and Ethiopia. The Newcastle-Ottawa scale (NOS), based on a star scoring system, was used to assess the quality of the included studies. The meta-analysis was conducted using STATA 16 software. The pooled prevalence of an adverse maternal outcome, fetal outcome, and association between adverse outcome and obstructed labor was calculated using a random-effects model. Egger’s test and funnel plot were used to evaluate publication bias.

Result

Eighty-seven studies were included in this review, with an overall sample size of 104259 women and 4952 newborns. The pooled incidence of maternal death was estimated to be 14.4% [14.14 (6.91–21.37). The pooled prevalence of uterine rupture and maternal near-miss was 41.18% (95% CI: 19.83, 62.54) and 30.5% [30.5 (11.40, 49.59) respectively. Other complications such as postpartum hemorrhage, sepsis, obstetric fistula, hysterectomy, bladder injury, cesarean section, and labor abnormalities were also reported. The pooled prevalence of perinatal death was 26.4% (26.4 (95% CI 15.18, 37.7). In addition, the association of obstructed labor with stillbirth, perinatal asphyxia, and meconium-stained amniotic fluid was also demonstrated.

Conclusions

In Ethiopia, the incidence of perinatal and maternal mortality among pregnant women with obstructed labor was high. The rate of maternal death and maternal near miss reported in this review was higher than incidences reported from high-income and most low and middle-income countries. Uterine rupture, postpartum hemorrhage, sepsis, fistula, hysterectomy, and bladder injury were also commonly reported. To improve the health outcomes of obstructed labor, it is recommended to address the three delay models: enhancing communities’ health-seeking behavior, enhancing transportation for an obstetric emergency with different stakeholders, and strengthening the capacity of health facilities to handle obstetric emergencies.

Improved maternal-fetal outcomes among emergency obstetric referrals following phone call communication at a teaching hospital in south western Uganda: a quasi-experimental study

BACKGROUND

Emergency obstetric referrals develop adverse maternal-fetal outcomes partly due to delays in offering appropriate care at referral hospitals especially in resource limited settings. Referral hospitals do not get prior communication of incoming referrals leading to inadequate preparedness and delays of care. Phone based innovations may bridge such communication challenges. We investigated effect of a phone call communication prior to referral of mothers in labour as intervention to reduce preparation delays and improve maternal-fetal outcome at a referral hospital in a resource limited setting.

METHODS

This was a quasi-experimental study with non-equivalent control group conducted at Mbarara Regional Referral Hospital (MRRH) in South Western Uganda from September 2020 to March 2021. Adverse maternal-fetal outcomes included: early neonatal death, fresh still birth, obstructed labour, ruptured uterus, maternal sepsis, low Apgar score, admission to neonatal ICU and hysterectomy. Exposure variable for intervention group was a phone call prior maternal referral from a lower health facility. We compared distribution of clinical characteristics and adverse maternal-fetal outcomes between intervention and control groups using Chi square or Fisher's exact test. We performed logistic regression to assess association between independent variables and adverse maternal-fetal outcomes.

RESULTS

We enrolled 177 participants: 75 in intervention group and 102 in control group. Participants had similar demographic characteristics. Three quarters (75.0%) of participants in control group delayed on admission waiting bench of MRRH compared to (40.0%) in intervention group [p =  < 0.001]. There were significantly more adverse maternal-fetal outcomes in control group than intervention group (obstructed labour [p = 0.026], low Apgar score [p = 0.013] and admission to neonatal high dependency unit [p =  < 0.001]). The phone call intervention was protective against adverse maternal-fetal outcome [aOR = 0.22; 95%CI: 0.09-0.44, p = 0.001].

CONCLUSION

The phone call intervention resulted in reduced delay to patient admission at a tertiary referral hospital in a resource limited setting, and is protective against adverse maternal-fetal outcomes. Incorporating the phone call communication intervention in the routine practice of emergency obstetric referrals from lower health facilities to regional referral hospitals may reduce both maternal and fetal morbidities.

Learning from maternal deaths due to uterine rupture: review of cases from peri-urban Uganda

BACKGROUND

Maternal deaths from uterine rupture continue to occur globally, with particularly high rates in sub-Saharan Africa. Maternal death reviews have been shown to be an effective part of cohesive strategies to prevent future deaths.

OBJECTIVE

This study aimed to conduct maternal death reviews for all deaths following uterine rupture in the study center, to assess preventability, and to synthesize key learning points that may help to prevent future maternal deaths following uterine rupture.

STUDY DESIGN

Thorough case reviews of all maternal deaths from 2016 to 2018 at the study center (a national referral hospital in urban Uganda) were conducted by trained multidisciplinary panels of obstetricians and midwives. Medical records of women who died following uterine rupture (n=37, 10.6% of all maternal deaths) were extracted for further analysis.

RESULTS

Most maternal deaths due to uterine rupture (36/37, 97%) were preventable, with most having been still potentially preventable after the women reached the study center (24/36, 67%). Obstructed labor was the leading cause of uterine rupture, accounting for 73% (27/37) of cases. Previous cesarean delivery was confirmed in 38% (14/37) of cases. The incidence of grand multiparity was 11% (4/37), and 11% (4/37) were primiparous. Most women (28/37, 76%) died within 24 hours of admission. On arrival at the study center, 19 (51%) were critically ill. Exploratory laparotomy was performed in 54% (20/37) of cases, and a further 35% (13/37) died while awaiting laparotomy. Four women died shortly after arrival at the study center (within 1 hour) and received basic resuscitative treatment; 27% (10/37) of women who died had received antenatal planning or preparation.

CONCLUSION

Most deaths due to uterine rupture were preventable. The key lessons that emerged from the reviews were: (1) careful birth preparation and complication awareness for women with known risk factors, (2) early recognition of obstructed labor, (3) close monitoring of obstetrical interventions known to be associated with uterine rupture, and (4) treating incipient or suspected uterine rupture as a time-critical obstetrical emergency. The recommendations emerging from our narrative reviews are suitable for implementation in low-resource obstetrical settings, where high numbers of deaths involving uterine rupture occur.

Risk Factors Associated with Uterine Rupture and Dehiscence: A Cross-Sectional Canadian Study

OBJECTIVE

 To compare maternal and perinatal risk factors associated with complete uterine rupture and uterine dehiscence.

METHODS

 Cross-sectional study of patients with uterine rupture/dehiscence from January 1998 to December 2017 (30 years) admitted at the Labor and Delivery Unit of a tertiary teaching hospital in Canada.

RESULTS

 There were 174 (0.1%) cases of uterine disruption (29 ruptures and 145 cases of dehiscence) out of 169,356 deliveries. There were associations between dehiscence and multiparity (odds ratio [OR]: 3.2; p = 0.02), elevated maternal body mass index (BMI; OR: 3.4; p = 0.02), attempt of vaginal birth after a cesarian section (OR: 2.9; p = 0.05) and 5-minute low Apgar score (OR: 5.9; p < 0.001). Uterine rupture was associated with preterm deliveries (36.5 ± 4.9 versus 38.2 ± 2.9; p = 0.006), postpartum hemorrhage (OR: 13.9; p < 0.001), hysterectomy (OR: 23.0; p = 0.002), and stillbirth (OR: 8.2; p < 0.001). There were no associations between uterine rupture and maternal age, gestational age, onset of labor, spontaneous or artificial rupture of membranes, use of oxytocin, type of uterine incision, and birthweight.

CONCLUSION

 This large cohort demonstrated that there are different risk factors associated with either uterine rupture or dehiscence. Uterine rupture still represents a great threat to fetal-maternal health and, differently from the common belief, uterine dehiscence can also compromise perinatal outcomes.
