Prevalence, perinatal outcomes and factors associated with neonatal sepsis in Nigeria

OBJECTIVE

To examine the prevalence, perinatal outcomes and factors associated with neonatal sepsis in referral-level facilities across Nigeria.

DESIGN

Secondary analysis of data from the Maternal and Perinatal Database for Quality, Equity and Dignity Programme in 54 referral-level hospitals across Nigeria.

SETTING

Records covering the period from 1 September 2019 to 31 August 2020.

POPULATION

Mothers admitted for birth during the study period, and their live newborns.

METHODS

Analysis of prevalence and sociodemographic and clinical factors associated with neonatal sepsis and perinatal outcomes. Multilevel logistic regression modelling identified factors associated with neonatal sepsis.

MAIN OUTCOME MEASURES

Neonatal sepsis and perinatal outcomes.

RESULTS

The prevalence of neonatal sepsis was 16.3 (95% CI 15.3-17.2) per 1000 live births (1113/68 459) with a 10.3% (115/1113) case fatality rate. Limited education, unemployment or employment in sales/trading/manual jobs, nulliparity/grand multiparity, chronic medical disorder, lack of antenatal care (ANC) or ANC outside the birthing hospital and referral for birth increased the odds of neonatal sepsis. Birthweight of <2500 g, non-spontaneous vaginal birth, preterm birth, prolonged rupture of membranes, APGAR score of <7 at 5 min, birth asphyxia, birth trauma or jaundice were associated with neonatal sepsis. Neonates with sepsis were more frequently admitted to a neonatal intensive care unit (1037/1110, 93.4% vs 8237/67 346, 12.2%) and experienced a higher rate of death (115/1113, 10.3% vs 933/67 343, 1.4%).

CONCLUSIONS

Neonatal sepsis remains a critical challenge in neonatal care, underscored by its high prevalence and mortality rate. The identification of maternal and neonatal risk factors underscores the importance of improved access to education and employment for women and targeted interventions in antenatal and intrapartum care.

Incidence, predictors and immediate neonatal outcomes of birth asphyxia in Nigeria

OBJECTIVE

To determine the incidence and sociodemographic and clinical risk factors associated with birth asphyxia and the immediate neonatal outcomes of birth asphyxia in Nigeria.

DESIGN

Secondary analysis of data from the Maternal and Perinatal Database for Quality, Equity and Dignity Programme.

SETTING

Fifty-four consenting referral-level hospitals (48 public and six private) across the six geopolitical zones of Nigeria.

POPULATION

Women (and their babies) who were admitted for delivery in the facilities between 1 September 2019 and 31 August 2020.

METHODS

Data were extracted and analysed on prevalence and sociodemographic and clinical factors associated with birth asphyxia and the immediate perinatal outcomes. Multilevel logistic regression modelling was used to ascertain the factors associated with birth asphyxia.

MAIN OUTCOME MEASURES

Incidence, case fatality rate and factors associated with birth asphyxia.

RESULTS

Of the available data, 65 383 (91.1%) women and 67 602 (90.9%) babies had complete data and were included in the analysis. The incidence of birth asphyxia was 3.0% (2027/67 602) and the case fatality rate was 16.8% (339/2022). The risk factors for birth asphyxia were uterine rupture, pre-eclampsia/eclampsia, abruptio placentae/placenta praevia, birth trauma, fetal distress and congenital anomaly. The following factors were independently associated with a risk of birth asphyxia: maternal age, woman's education level, husband's occupation, parity, antenatal care, referral status, cadre of health professional present at the birth, sex of the newborn, birthweight and mode of birth. Common adverse neonatal outcomes included: admission to a special care baby unit (SCBU), 88.4%; early neonatal death, 14.2%; neonatal sepsis, 4.5%; and respiratory distress, 4.4%.

CONCLUSIONS

The incidence of reported birth asphyxia in the participating facilities was low, with around one in six or seven babies with birth asphyxia dying. Factors associated with birth asphyxia included sociodemographic and clinical considerations, underscoring a need for a comprehensive approach focused on the empowerment of women and ensuring access to quality antenatal, intrapartum and postnatal care.

The impact of COVID-19 on the birth rate in Nigeria: a report from population-based registries

Background and objectives

Coronavirus disease 2019 (COVID-19) is a pandemic that has become a major source of morbidity and mortality worldwide, affecting the physical and mental health of individuals influencing reproduction. Despite the threat, it poses to maternal health in sub-Saharan Africa and Nigeria, there is little or no data on the impact it has on fertility, conception, gestation and birth. To compare the birth rate between pre-COVID and COVID times using selected months of the year.

Materials and methods

This was a secondary analysis of cross-sectional analytical study data from the birth registries of three tertiary hospitals, comparing two years [2019 (Pre-COVID)] versus [2020 (COVID era)] using three months of the year (October to December). The data relied upon was obtained from birth registries in three busy maternity clinics all within tertiary hospitals in South-East Nigeria and we aimed at discussing the potential impacts of COVID-19 on fertility in Nigeria. The secondary outcome measures were; mode of delivery, booking status of the participants, maternal age and occupation.

Results

There was a significant decrease in tertiary-hospital based birth rate by 92 births (P = 0.0009; 95% CI: -16.0519 to -4.1481) among mothers in all the three hospitals in 2020 during the COVID period (post lockdown months) of October to December. There was a significant difference in the mode of delivery for mothers (P = 0.0096) with a 95% confidence interval of 1.0664 to 1.5916, as more gave birth through vaginal delivery during the 2020 COVID-19 period than pre-COVID-19.

Conclusion

Tertiary-hospital based birth rates were reduced during the pandemic. Our multi-centre study extrapolated on possible factors that may have played a role in this decline in their birth rate, which includes but is not limited to; decreased access to hospital care due to the total lockdowns/curfews and worsening inflation and economic recession in the country.

Cesarean section rate and outcomes during and before the first wave of COVID-19 pandemic

Objectives:

The objective of the study was to assess how the current COVID-19 pandemic has affected cesarean section (C-section) rates, indications, and peripartum outcomes.

Methods:

This was a retrospective cross-sectional study that compared a 3-month rates of and indications for C-sections at three tertiary health care institutions in Nigeria before (October 2019–December 2019) and during the first wave of COVID-19 pandemic (March 2020–May 2020). Primary outcomes were C-section rate and indications between the two periods. Data were analyzed using SPSS 26.0 IBM Corporation. Rates and odds ratios with 95% confidence intervals were used to quantify indications and peripartum outcomes and statistical significance was accepted when p value was <0.05.

Results:

The baseline characteristics of the two groups were similar. The C-section rate during the COVID-19 period was significantly less than the period prior to the pandemic (237/580, 40.0% vs 390/833, 46.8%; p = 0.027). The rates of postdatism (odds ratio = 1.47, 95% confidence interval = 1.05–2.05, p = 0.022), fetal distress (odds ratio = 3.06, 95% confidence interval = 1.55–6.06, p = 0.017), emergency C-section (odds ratio = 1.43, 95% confidence interval = 1.01–2.05, p = 0.042), and anemia (odds ratio = 1.84, 95% confidence interval = 1.12–3.03, p = 0.016) were significantly higher during the pandemic than prepandemic.

Conclusion:

The overall C-section rate during the first wave of COVID-19 was significantly lower than the prepandemic period. There were higher rates of postdatism, fetal distress, emergency C-section, and postpartum anemia. Further studies on this changing C-section trend during the pandemic are needed.

Obstetricians' attitudes to caesarean delivery on maternal request in Nigeria

The study was done to determine obstetricians' attitude to and factors predicting obstetricians' acceptance of caesarean delivery on maternal request in Nigeria. Nigerian obstetricians were asked to respond to case scenarios depicting caesarean delivery on maternal request without medical indications and the reasons for their responses. The case scenarios were designed from previously published reasons for caesarean delivery on maternal request from Nigeria. Multiple logistic regressions analysis was done to determine factors predicting obstetricians' acceptance of caesarean delivery on maternal request out of respect for maternal autonomy. The majority (53.1%) of the respondents would accept caesarean delivery on maternal request out of respect for maternal autonomy. Caesarean requests backed up by social mitigating circumstances of previous childlessness and previous negative labour experience received significantly higher acceptances than requests with no back-up mitigating circumstances (p < 0.0001). A good proportion (48.8%) of Nigerian obstetricians had performed at least one caesarean on maternal request. Obstetricians' bio-professional characteristics do not influence their attitude to request caesarean delivery on maternal request. Some obstetricians expressed fear of legal consequences from caesarean delivery on maternal request.
