A population-based estimation of maternal mortality in Lagos State, Nigeria using the indirect sisterhood method.

BACKGROUND: Pregnancy and delivery deaths represent a risk to women, particularly those living in low- and middle-income countries (LMICs). This population-based survey was conducted to provide estimates of the maternal mortality ratio (MMR) in Lagos Nigeria. METHODS: A community-based, cross-sectional study was conducted in mapped Wards and Enumeration Areas (EA) of all Local Government Areas (LGAs) in Lagos, among 9,986 women of reproductive age (15-49 years) from April to August 2022 using a 2-stage cluster sampling technique. A semi-structured, pre-tested questionnaire adapted from nationally representative surveys was administered using REDCap by trained field assistants for data collection on socio-demographics, reproductive health, fertility, and maternal mortality. Data were analysed using SPSS and MMR was estimated using the indirect sisterhood method. Ethical approval was obtained from the Lagos State University Teaching Hospital Health Research and Ethics Committee. RESULTS: Most of the respondents (28.7%) were aged 25-29 years. Out of 546 deceased sisters reported, 120 (22%) died from maternal causes. Sisters of the deceased aged 20-24 reported almost half of the deaths (46.7%) as due to maternal causes, while those aged 45-49 reported the highest number of deceased sisters who died from other causes (90.2%). The total fertility rate (TFR) was calculated as 3.807, the Lifetime Risk (LTR) of maternal death was 0.0196 or 1-in-51, and the MMR was 430 per 100,000 [95% CI: 360-510]. CONCLUSION: Our findings show that the maternal mortality rate for Lagos remains unacceptable and has not changed significantly over time in actual terms. There is need to develop and intensify community-based intervention strategies, programs for private hospitals, monitor MMR trends, identify and contextually address barriers at all levels of maternal care.

Barriers to health in women of reproductive age living with or at risk of non-communicable diseases in Nigeria: a Photovoice study.

BACKGROUND: Nigeria has one of the highest maternal mortality ratios (MMR) globally with an MMR of 512 (per 100,000 live births) and the proportion of maternal deaths due to non-communicable diseases (NCDs) is increasing. While evidence shows that many of these deaths are preventable, limited attention is being paid to the unique vulnerabilities and experiences of women of reproductive age (WRA) with NCDs and their risk factors, as well as the barriers to the screening, diagnosis, and management of these diseases in Nigeria. METHODS: This study explored the lives of WRA in Lagos and Federal Capital Territory in Nigeria from May to June 2019 using a community-based participatory research (CBPR) methodology called Photovoice which is aligned with CBPR as it includes procedures such as the identification of important community issues, discussion of photo assignments and data analysis. Twenty-four women of reproductive age were provided with digital cameras and trained on how to capture photos that conveyed their current health, healthcare utilization and engagement, and experience journeys. Individual interviews with the women were held for an in-depth exploration of the photographs. The data was then analysed thematically. RESULTS: Six distinct themes were identified across the barriers highlighted by the women: food and nutrition, home and family, neighborhood-built environment, economic instability, religion and spirituality and low prioritization of self-care. These themes captured the challenge of reduced agency, limited contribution and participation, and a complex relationship between visible and invisible illness. CONCLUSION: The perspectives of WRA in Nigeria obtained through this qualitative research provided a strong substratum for understanding the environmental barriers that predispose WRA to NCDs in Nigeria. The results of the study are useful for the improvement of woman-centred services of prevention, diagnosis, and management of NCD risk factors across the maternal and reproductive health care continuum in Nigeria.

Maternal death review and outcomes: An assessment in Lagos State, Nigeria.

The objective of the study was to investigate the results of Maternal and Perinatal Death Surveillance and Response (MPDSR) conducted in three referral hospitals in Lagos State, Nigeria over a two-year period and to report the outcomes and the lessons learned. MPDRS panels were constituted in the three hospitals, and beginning from January 2015, we conducted monthly MPDSR in the three hospitals using a nationally approved protocol. Data on births and deaths and causes of deaths as identified by the MPDSR panels were collated in the hospitals. The results show that over a 21-month period (January 1, 2015 -September 30, 2016), maternal mortality ratio (MMR) remained high in the hospitals. Although there was a trend towards an increase in MMR in Lagos Island Maternity Hospital and Gbagada General Hospital, and a trend towards a decline in Ajeromi Hospital, none of these trends were statistically significant. Eclampsia, primary post-partum haemorrhage, obstructed labour and puerperal sepsis were the leading obstetric causes of death. By contrast, delay in arrival in hospital, the lack of antenatal care and patients' refusal to receive recommended treatment were the patients' associated causes of death, while delay in treatment, poor use of treatment protocols, lack of equipment and lack of skills by providers to use available equipment were the identified facility-related causes of death. Failure to address the patients and facility-related causes of maternal mortality possibly accounted for the persistently high maternal mortality ratio in the hospitals. We conclude that interventions aimed at redressing all causes of maternal deaths identified in the reviews will likely reduce the maternal mortality ratios in the hospitals.

Maternal detection of neonatal jaundice during birth hospitalization using a novel two-color icterometer.

BACKGROUND: Mothers are frequently the first to observe the onset of jaundice in their newborn infants before the decision to seek treatment. However, simple-to-use tools that could facilitate early detection of jaundice and assist mothers to seek professional care, especially after hospital discharge, are rare. This study therefore, set out to evaluate the performance of a -two-color icterometer (Bilistrip™) as a possible screening tool for detecting significant jaundice by mothers or care-givers in the first week of life. METHODS: Prior to discharge, mothers in a maternity hospital were trained to use the Bilistrip™ on the blanched skin of their baby's nose to ascertain absence (Light Yellow) or presence (Dark Yellow) of significant jaundice. Their babies had transcutaneous bilirubin (TcB) measurements independently, along with total serum bilirubin (TSB) if indicated. The reliability of Bilistrip™ as a screening test for significant jaundice was determined at different TcB and TSB thresholds. The predictive performance of Bilistrip™ was also evaluated with multivariable logistic regression. RESULTS: Some 2492 mother-infant pairs were enrolled over 15 months, of which 347 (13.9%) chose Dark Yellow. The mean TcB for Dark Yellow (10mg/dL) was significantly higher (p<0.001) than for Light Yellow (6.1mg/dL). Bilistrip™ showed increasing sensitivity (47.0% - 92.6%) and negative predictive value (NPV) (91.4% - 99.9%) for selected TcB thresholds (≥10mg/dL, ≥12mg/dL, ≥15mg/dL, and ≥17mg/dL). Among neonates with TSB measurements (n = 124), Bilistrip™ was associated also with increasing sensitivity (86.8% - 100%) and NPV (62.5% - 100%). The sensitivity and NPV for detecting neonates requiring phototherapy were 95.8% respectively. Only one of the 24 neonates who required phototherapy was missed by the Bilistrip™. CONCLUSIONS: Bilistrip™ is a potential decision-making tool for empowering mothers to detect neonates with clinically significant jaundice that may require close monitoring or treatment, and neonates not requiring treatment for jaundice in the first week of life.

Transcutaneous bilirubin nomograms in African neonates.

BACKGROUND: The use of transcutaneous bilirubin (TcB) as a screening tool, based on relevant population-specific nomogram, or proxy for total serum bilirubin (TSB) levels in assessing the risk of subsequent hyperbilirubinemia is supported by several clinical guidelines on the management of neonatal hyperbilirubinemia. However, while TcB has been found to significantly over-estimate TSB in neonates of African-American ancestry, with variations across TcB devices, no nomogram has been specifically reported for this racial group. This study therefore set out to develop TcB nomograms for healthy late pre-term and term black African neonates derived from two widely used bilirubinometers. METHODS: A retrospective analysis of 12,377 TcB measurements obtained from 6,373 neonates in the first postnatal week, over a period of 48 months using Bilichek and JM-103 bilirubinometers. TcB percentiles were computed from hour-specific TcB values and nomograms developed for each of the screening devices. Predictive ability of the 75th and 95th percentiles to detect significant hyperbilirubinemia was evaluated between 24-96 hours of age. The 95th percentile curve was compared with those from other populations. RESULTS: The velocity of TcB rise at 75th and 95th percentiles was generally higher with JM-103 than Bilichek. Both percentiles also peaked at higher TcB levels with JM-103. The 95th percentile for both instruments showed a downward trend as from approximately 114 hours. Both instruments had high negative predictive values across the selected time-epochs and lower discriminatory ability than reported in non-black populations. CONCLUSIONS: The predictive utility of TcB as a potential screening tool varies across devices in black African neonates with or without risk of significant hyperbilirubinemia, and lower than levels reported in non-black populations. Equipment-specific nomograms should be considered for TcB monitoring in this racial population where TSB is not routinely available.

Differences Between Transcutaneous and Serum Bilirubin Measurements in Black African Neonates.

BACKGROUND AND OBJECTIVE: Transcutaneous bilirubin (TcB) correlates positively with total serum bilirubin (TSB) across different racial populations. However, little is known about the pattern of divergence between TcB and TSB at individual patient-level and the relationship with TcB measuring techniques among African neonates. This study, therefore, investigates TcB-TSB discrepancies and the contribution of 2 models of transcutaneous bilirubinometers to the observed divergence in a black African population. METHODS: Medical records were retrieved for late preterm and term infants with 1 to 3 pairs of TcB and TSB measurements between December 2011 to June 2015 in Nigeria. Divergence between TcB and TSB values for each infant was determined and the associated factors explored with generalized estimating equations for logistic regression. Contributions of BiliChek and JM-103 transcutaneous bilirubinometers to the divergence were further explored through linear regression and Bland-Altman analysis. RESULTS: Overall, 2107 TcB/TSB measurements from 1553 infants were analyzed. TSB was overestimated by ≥2 mg/dL in 64.5%, ≥3 mg/dL in 42.7%, and ≥4 mg/dL in 25.7% of all measurements. In contrast, TSB was underestimated by ≥2 mg/dL in 1.1%, ≥3 mg/dL in 0.5%, and ≥4 mg/dL in 0.3% of all recordings. Postnatal age, feeding mode, and type of TcB instrument were predictive of TSB overestimation. The JM-103 was associated with greater imprecision than BiliChek at all TSB levels. CONCLUSIONS: BiliChek and JM-103 bilirubinometers significantly overestimate TSB in black African neonates and may result in unnecessary or excessive treatments. Additional development of appropriate bilirubin determination devices for this racial group, especially in resource-limited settings, is warranted.

Prevalence of HIV among women with vaginal discharge in a gynecological clinic.

OBJECTIVE: Vaginal discharge is a common complaint among women with sexually transmitted diseases (STDs) in Nigeria. Given the association between STDs and HIV and the alarming rise in the prevalence of HIV in Nigeria, we performed this study to determine the prevalence of HIV in patients with vaginal discharge. STUDY DESIGN: Between April 2000 and August 2000, women who attended the Lagos University Teaching Hospital and complained of vaginal discharge were adequately counseled for HIV serotest. High vaginal/endocervical swabs and venous blood were taken for microbiological studies and HIV serotest, respectively. RESULTS: Out of the 230 women counseled for HIV serotest 140 (60.9%) consented. The mean age of the 140 was 31.1+/-6.9 years (range 18-50 years). In 31 (22.1%), Candida albicans was isolated, in 26 Gardnerella vaginalis (18.8%), in 17 Staphylococcal spp. (12.1%); and E. coli, Trichomonas vaginalis, and Neisseria gonococcus in 7.9%, 4.3%, and 1.4%, respectively. Four (2.9%) of the 140 patients were HIV seropositive, and all had Candida albicans isolated. The prevalence of HIV among patients with Candida albicans was 12.9%. Association between HIV seropositivity and Candida albicans infection is significant (X2=14.48; p=0.002). CONCLUSION: Candida albicans is a common cause of vaginal discharge among HIV-seropositive women in Lagos.
