Predictors, prevalence and outcome of hypertensive disorders in pregnancy in Nigerian tertiary health facilities: A secondary analysis of the Maternal and Perinatal Database for Quality, Equity and Dignity Programme.

OBJECTIVE: Determine prevalence, risk factors and outcomes of hypertensive disorders in pregnancy (HDP). DESIGN: Cross-sectional analysis of data captured in the Maternal and Perinatal Database for Quality, Equity and Dignity (MPD-4-QED) between September 2019 and August 2020. SETTING: Fifty-four referral level facilities in Nigeria. POPULATION: Women whose pregnancy ended (irrespective of the location or duration of pregnancy) or who were admitted within 42 days of delivery. METHODS: Descriptive statistics and multilevel mixed-effects logistic regression models. MAIN OUTCOME MEASURES: Prevalence of HDP, sociodemographic and clinical factors associated with HDP and perinatal outcomes. RESULTS: Among the 71 758 women 6.4% had HDP and gestational hypertension accounted for 49.8%. Preeclampsia and eclampsia were observed in 9.5% and 7.0% of all pregnancies, respectively. The predictors of HDP were age over 35 years (OR1.96, 95% CI 1.82-2.12; p < 0.001), lack of formal educational (OR 1.18, 95% CI 1.06-1.32; p = 0.002), primary level of education (OR 1.20, 95% CI 1.03-1.4; p < 0.002), nulliparity (OR 1.21, 95% CI 1.12-1.31; p < 0.001), grand-multiparity (OR 1.36, 95%CI 1.21-1.52; p < 0.001), previous caesarean section (OR 1.26, 95%CI 1.15-1.38; p < 0.001) and previous miscarriage (OR 1.22, 95% CI 1.13-1.31; p < 0.001). Overall 3.7% of the patients with HDP died, with eclampsia having the highest case fatality rate of 27.9%. Stillbirth occurred in 11.9% of pregnancies with hypertensive disorders. CONCLUSIONS: Hypertensive disorders in pregnancy are not uncommon in Nigeria. They are associated with adverse outcomes with over one-quarter of women with eclampsia dying. The main predictors include older age, poor education, extremes of parity and previous CS or miscarriage. Maternal and perinatal outcomes are poor with about a quarter developing complications and about 1 in 10 having stillbirths.

Maternal morbidity and death associated with pregnancy loss before 28 weeks in Nigeria.

OBJECTIVE: To determine the prevalence of maternal morbidity and death from pregnancy loss before 28 weeks in referral-level hospitals in Nigeria. DESIGN: Secondary analysis of a nationwide cross-sectional study. SETTING: Fifty-four referral-level hospitals. POPULATION: Women admitted for complications arising from pregnancy loss before 28 weeks between 1 September 2019 to 31 August 2020. METHODS: Frequency and type of pregnancy loss were calculated using the extracted data. Multilevel logistic regression was used to determine sociodemographic and clinical factors associated with early pregnancy loss. Factors contributing to death were also analysed. MAIN OUTCOME MEASURES: Prevalence and outcome of pregnancy loss at <28 weeks; sociodemographic and clinical predictors of morbidity after early pregnancy loss; contributory factors to death. RESULTS: Of the 4798 women who had pregnancy loss at <28 weeks of pregnancy, spontaneous abortion accounted for 49.2%, followed by missed abortion (26.9%) and ectopic pregnancy (15%). Seven hundred women (14.6%) had a complication following pregnancy loss and 99 women died (2.1%). Most complications (26%) and deaths (7%) occurred after induced abortion. Haemorrhage was the most frequent complication in all types of pregnancy loss with 11.5% in molar pregnancy and 6.9% following induced abortion. Predictors of complication or death were low maternal education, husband who was not gainfully employed, grand-multipara, pre-existing chronic medical condition and referral from another facility or informal setting. CONCLUSION: Pregnancy loss before 28 weeks is a significant contributor to high maternal morbidity and mortality in Nigeria. Socio-economic factors and delays in referral to higher levels of care contribute significantly to poor outcomes for women.

Determinants and outcomes of preterm births in Nigerian tertiary facilities.

OBJECTIVE: To describe the incidence, and sociodemographic and clinical factors associated with preterm birth and perinatal mortality in Nigeria. DESIGN: Secondary analysis of data collected through the Maternal Perinatal Database for Quality, Equity and Dignity (MPD-4-QED) Programme. SETTING: Data from births in 54 referral-level hospitals across Nigeria between 1 September 2019 and 31 August 2020. POPULATION: A total of 69 698 births. METHODS: Multilevel modelling was used to determine the factors associated with preterm birth and perinatal mortality. OUTCOME MEASURES: Preterm birth and preterm perinatal mortality. RESULTS: Of 62 383 live births, 9547 were preterm (153 per 1000 live births). Maternal age (<20 years - adjusted odds ratio [aOR] 1.52, 95% CI 1.36-1.71; >35 years - aOR 1.23, 95% CI 1.16-1.30), no formal education (aOR 1.68, 95% CI 1.54-1.84), partner not gainfully employed (aOR 1.94, 95% CI 1.61-2.34) and no antenatal care (aOR 2.62, 95% CI 2.42-2.84) were associated with preterm births. Early neonatal mortality for preterm neonates was 47.2 per 1000 preterm live births (451/9547). Father's occupation (manual labour aOR 1.52, 95% CI 1.20-1.93), hypertensive disorders of pregnancy (aOR 1.37, 95% CI 1.02-1.83), no antenatal care (aOR 2.74, 95% CI 2.04-3.67), earlier gestation (28 to <32 weeks - aOR 2.94, 95% CI 2.15-4.10; 32 to <34 weeks - aOR 1.80, 95% CI 1.3-2.44) and birthweight <1000 g (aOR 21.35, 95% CI 12.54-36.33) were associated with preterm perinatal mortality. CONCLUSIONS: Preterm birth and perinatal mortality in Nigeria are high. Efforts should be made to enhance access to quality health care during pregnancy, delivery and the neonatal period, and improve the parental socio-economic status.

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.

Outcomes and quality of care for women and their babies after caesarean section in Nigeria.

OBJECTIVE: To describe the outcomes and quality of care for women and their babies after caesarean section (CS) in Nigerian referral-level hospitals. DESIGN: Secondary analysis of a nationwide cross-sectional study. SETTING: Fifty-four referral-level hospitals. POPULATION: All women giving birth in the participating facilities between 1 September 2019 and 31 August 2020. METHODS: Data for the women were extracted, including sociodemographic data, clinical information, mode of birth, and maternal and perinatal outcomes. A conceptual hierarchical framework was employed to explore the sociodemographic and clinical factors associated with maternal and perinatal death in women who had an emergency CS. MAIN OUTCOME MEASURES: Overall CS rate, outcomes for women who had CS, and factors associated with maternal and perinatal mortality. RESULTS: The overall CS rate was 33.3% (22 838/68 640). The majority of CS deliveries were emergency cases (62.8%) and 8.1% of CS deliveries had complications after delivery, which were more common after an emergency CS. There were 179 (0.8%) maternal deaths in women who had a CS and 29.6% resulted from complications of hypertensive disorders of pregnancy. The overall maternal mortality rate in women who delivered by CS was 778 per 100 000 live births, whereas the perinatal mortality at birth was 51 per 1000 live births. Factors associated with maternal mortality in women who had an emergency CS were being <20 or >35 years of age, having a lower level of education and being referred from another facility or informal setting. CONCLUSIONS: One-third of births were delivered via CS (mostly emergency), with almost one in ten women experiencing a complication after a CS. To improve outcomes, hospitals should invest in care and remove obstacles to accessible quality CS services.

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.

Determinants of obstructed labour and associated outcomes in 54 referral hospitals in Nigeria.

OBJECTIVE: To estimate the prevalence of obstructed labour, associated risk factors and outcomes across a network of referral hospitals in Nigeria. DESIGN: Retrospective observational study. SETTING: A total of 54 referral-level hospitals across the six geopolitical regions of Nigeria. POPULATION: Pregnant women who were diagnosed with obstructed labour during childbirth and subsequently underwent an emergency caesarean section between 1 September 2019 and 31 August 2020. METHODS: Secondary analysis of routine maternity care data sets. Random-effects multivariable logistic regression was used to ascertain the factors associated with obstructed labour. MAIN OUTCOME MEASURES: Risk factors for obstructed labour and related postpartum complications, including intrapartum stillbirth, maternal death, uterine rupture, postpartum haemorrhage and sepsis. RESULTS: Obstructed labour was diagnosed in 1186 (1.7%) women. Among these women, 31 (2.6%) cases resulted in maternal death and 199 (16.8%) cases resulted in postpartum complications. Women under 20 years of age (OR 2.03, 95% CI 1.50-2.75), who lacked formal education (OR 1.88, 95% CI 1.55-2.30), were unemployed (OR 1.94, 95% CI 1.57-2.41), were nulliparous (OR 2.11, 95% CI 1.83-2.43), did not receive antenatal care (OR 3.34, 95% CI 2.53-4.41) or received antenatal care in an informal healthcare setting (OR 8.18, 95% CI 4.41-15.14) were more likely to experience obstructed labour. Ineffective referral systems were identified as a major contributor to maternal death. CONCLUSIONS: Modifiable factors contributing to the prevalence of obstructed labour and associated adverse outcomes in Nigeria can be addressed through targeted policies and clinical interventions.

Burden and outcomes of postpartum haemorrhage in Nigerian referral-level hospitals.

OBJECTIVE: To determine the prevalence of primary postpartum haemorrhage (PPH), risk factors, and maternal and neonatal outcomes in a multicentre study across Nigeria. DESIGN: A secondary data analysis using a cross-sectional design. SETTING: Referral-level hospitals (48 public and six private facilities). POPULATION: Women admitted for birth between 1 September 2019 and 31 August 2020. METHODS: Data collected over a 1-year period from the Maternal and Perinatal Database for Quality, Equity and Dignity programme in Nigeria were analysed, stratified by mode of delivery (vaginal or caesarean), using a mixed-effects logistic regression model. MAIN OUTCOME MEASURES: Prevalence of PPH and maternal and neonatal outcomes. RESULTS: Of 68 754 women, 2169 (3.2%, 95% CI 3.07%-3.30%) had PPH, with a prevalence of 2.7% (95% CI 2.55%-2.85%) and 4.0% (95% CI 3.75%-4.25%) for vaginal and caesarean deliveries, respectively. Factors associated with PPH following vaginal delivery were: no formal education (aOR 2.2, 95% CI 1.8-2.6, P < 0.001); multiple pregnancy (aOR 2.7, 95% CI 2.1-3.5, P < 0.001); and antepartum haemorrhage (aOR 11.7, 95% CI 9.4-14.7, P < 0.001). Factors associated with PPH in a caesarean delivery were: maternal age of >35 years (aOR 1.7, 95% CI 1.5-2.0, P < 0.001); referral from informal setting (aOR 2.4, 95% CI 1.4-4.0, P = 0.002); and antepartum haemorrhage (aOR 3.7, 95% CI 2.8-4.7, P < 0.001). Maternal mortality occurred in 4.8% (104/2169) of deliveries overall, and in 8.5% (101/1182) of intensive care unit admissions. One-quarter of all infants were stillborn (570/2307), representing 23.9% (429/1796) of neonatal intensive care unit admissions. CONCLUSIONS: A PPH prevalence of 3.2% can be reduced with improved access to skilled birth attendants.

Quality and outcomes of maternal and perinatal care for 76,563 pregnancies reported in a nationwide network of Nigerian referral-level hospitals.

Background: The WHO in collaboration with the Nigeria Federal Ministry of Health, established a nationwide electronic data platform across referral-level hospitals. We report the burden of maternal, foetal and neonatal complications and quality and outcomes of care during the first year. Methods: Data were analysed from 76,563 women who were admitted for delivery or on account of complications within 42 days of delivery or termination of pregnancy from September 2019 to August 2020 across the 54 hospitals included in the Maternal and Perinatal Database for Quality, Equity and Dignity programme. Findings: Participating hospitals reported 69,055 live births, 4,498 stillbirths and 1,090 early neonatal deaths. 44,614 women (58·3%) had at least one pregnancy complication, out of which 6,618 women (8·6%) met our criteria for potentially life-threatening complications, and 940 women (1·2%) died. Leading causes of maternal death were eclampsia (n = 187,20·6%), postpartum haemorrhage (PPH) (n = 103,11·4%), and sepsis (n = 99,10·8%). Antepartum hypoxia (n = 1455,31·1%) and acute intrapartum events (n = 913,19·6%) were the leading causes of perinatal death. Predictors of maternal and perinatal death were similar: low maternal education, lack of antenatal care, referral from other facility, previous caesarean section, latent-phase labour admission, operative vaginal birth, non-use of a labour monitoring tool, no labour companion, and non-use of uterotonic for PPH prevention. Interpretation: This nationwide programme for routine data aggregation shows that maternal and perinatal mortality reduction strategies in Nigeria require a multisectoral approach. Several lives could be saved in the short term by addressing key predictors of death, including gaps in the coverage of internationally recommended interventions such as companionship in labour and use of labour monitoring tool. Funding: This work was funded by MSD for Mothers; and UNDP/UNFPA/ UNICEF/WHO/World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), a co-sponsored programme executed by the World Health Organization (WHO).

What Are the Contextual Enablers and Impacts of Using Digital Technology to Extend Maternal and Child Health Services to Rural Areas? Findings of a Qualitative Study From Nigeria.

Background: Strengthening health systems to improve access to maternity services remains challenging for Nigeria due partly to weak and irregular in-service training and deficient data management. This paper reports the implementation of digital health tools for video training (VTR) of health workers and digitization of health data at scale, supported by satellite communications (SatCom) technology and existing 3G mobile networks. Objective: To understand whether, and under what circumstances using digital interventions to extend maternal, newborn and child health (MNCH) services to remote areas of Nigeria improved standards of healthcare delivery. Methods: From March 2017 to March 2019, VTR and data digitization interventions were delivered in 126 facilities across three states of Nigeria. Data collection combined documents review with 294 semi-structured interviews of stakeholders across four phases (baseline, midline, endline, and 12-months post-project closedown) to assess acceptability and impacts of digital interventions. Data was analyzed using a framework approach, drawing on a modified Technology Acceptance Model to identify factors that shaped technology adoption and use. Results: Analysis of documents and interview transcripts revealed that a supportive policy environment, and track record of private-public partnerships facilitated adoption of technology. The determinants of technology acceptance among health workers included ease of use, perceived usefulness, and prior familiarity with technology. Perceptions of impact suggested that at the micro (individual) level, repeated engagement with clinical videos increased staff knowledge, motivation and confidence to perform healthcare roles. At meso (organizational) level, better-trained staff felt supported and empowered to provide respectful healthcare and improved management of obstetric complications, triggering increased use of MNCH services. The macro level saw greater use of reliable and accurate data for policymaking. Conclusions: Simultaneous and sustained implementation of VTR and data digitization at scale enabled through SatCom and 3G mobile networks are feasible approaches for supporting improvements in staff confidence and motivation and reported MNCH practices. By identifying mechanisms of impact of digital interventions on micro, meso, and macro levels of the health system, the study extends the evidence base for effectiveness of digital health and theoretical underpinnings to guide further technology use for improving MNCH services in low resource settings.

Acceptability and Potential Effectiveness of eHealth Tools for Training Primary Health Workers From Nigeria at Scale: Mixed Methods, Uncontrolled Before-and-After Study.

BACKGROUND: The in-service training of frontline health workers (FHWs) in primary health care facilities plays an important role in improving the standard of health care delivery. However, it is often expensive and requires FHWs to leave their posts in rural areas to attend courses in urban centers. This study reports the implementation of a digital health tool for providing video training (VTR) on maternal, newborn, and child health (MNCH) care to provide in-service training at scale without interrupting health services. The VTR intervention was supported by satellite communications technology and existing 3G mobile networks. OBJECTIVE: This study aims to determine the feasibility and acceptability of these digital health tools and their potential effectiveness in improving clinical knowledge, attitudes, and practices related to MNCH care. METHODS: A mixed methods design, including an uncontrolled pre- and postquantitative evaluation, was adopted. From October 2017 to May 2018, a VTR mobile intervention was delivered to FHWs in 3 states of Nigeria. We examined changes in workers' knowledge and confidence in delivering MNCH services through a pre- and posttest survey. Stakeholders' experiences with the intervention were explored through semistructured interviews that drew on the technology acceptance model to frame contextual factors that shaped the intervention's acceptability and usability in the work environment. RESULTS: In total, 328 FHWs completed both pre- and posttests. FHWs achieved a mean pretest score of 51% (95% CI 48%-54%) and mean posttest score of 69% (95% CI 66%-72%), reflecting, after adjusting for key covariates, a mean increase between the pre- and posttest of 17 percentage points (95% CI 15-19; P<.001). Variation was identified in pre- and posttest scores by the sex and location of participants alongside topic-specific areas where scores were lowest. Stakeholder interviews suggested a wide acceptance of VTR Mobile (delivered via digital technology) as an important tool for enhancing the quality of training, reinforcing knowledge, and improving health outcomes. CONCLUSIONS: This study found that VTR supported through a digital technology approach is a feasible and acceptable approach for supporting improvements in clinical knowledge, attitudes, and reported practices in MNCH. The determinants of technology acceptance included ease of use, perceived usefulness, access to technology and training contents, and the cost-effectiveness of VTR, whereas barriers to the adoption of VTR were poor electricity supply, poor internet connection, and FHWs' workload. The evaluation also identified the mechanisms of the impact of delivering VTR Mobile at scale on the micro (individual), meso (organizational), and macro (policy) levels of the health system. Future research is required to explore the translation of this digital health approach for the VTR of FHWs and its impact across low-resource settings to ameliorate the financial and time costs of training and support high-quality MNCH care delivery.

Adherence to Guidelines in Postpartum Management of Hypertensive Disorders in Pregnancy in Tertiary Health Facilities in Nigeria: A Multi-centre Study.

Hypertensive disorders in pregnancy (HDPs) are a leading cause of maternal morbidity and mortality. Available guidelines for their postpartum management are expected to be optimally utilized. This study aimed to determine adherence to guidelines in selected Nigerian tertiary hospitals. It was nested in a cohort of women with HDPs who delivered in eight facilities between October 2017 and June 2018. Nine weeks after delivery, their cases were evaluated on prespecified indicators and supplemented with interviews. The level of adherence to the guidelines was determined using descriptive analyses, including frequencies, percentages, means, and standard deviations, as well as charts. Of the 366 participants, 33 (9%), 75 (20%), 200 (55%), and 58 (16%) had chronic hypertension, gestational hypertension, preeclampsia, and eclampsia, respectively. Only about a third had their blood pressure measured between postpartum days three and five. Similarly, a third of those with persistent hypertension (≥140/90 mmHg) were not on antihypertensive medications within the first week postpartum. In addition, 37% and 42% of participants were not counseled on contraceptives and early subsequent antenatal visits, respectively. Among those with preeclampsia/eclampsia, 93% were not offered postpartum screening for thromboprophylaxis. Although all women with preeclampsia/eclampsia remained hypertensive two weeks after discharge, only 24% had medical reviews. Overall, only 58% and 44% of indicators were adhered to among all HDPs and preeclampsia/eclampsia-specific indicators, respectively. Level of adherence to guidelines on postpartum management of HDPs in Nigerian tertiary hospitals is poor. It is recommended that institutionalization of guidelines be prioritized and linked to the entire continuum from preconception through longer term postpartum care.

Disparities in clinical features and outcomes of peripartum cardiomyopathy in high versus low prevalent regions in Nigeria.

AIMS: The prospective, multicentre Peripartum Cardiomyopathy in Nigeria (PEACE) registry originally demonstrated a high prevalence of peripartum cardiomyopathy (PPCM) among patients originating from Kano, North-West Nigeria. In a post hoc analysis, we sought to determine if this phenomenon was characterized by a differential case profile and outcome among PPCM cases originating elsewhere. METHODS AND RESULTS: Overall, 199 (81.6%) of a total 244 PPCM patients were recruited from three sites in Kano, compared with 45 patients (18.4%) from 11 widely dispersed centres across Nigeria. Presence and extent of ventricular myocardial remodelling during follow-up, relative to baseline status, were assessed by echocardiography. During median 17 months follow-up, Kano patients demonstrated significantly better myocardial reverse remodelling than patients from other sites. Overall, 50.6% of patients from Kano versus 28.6% from other regions were asymptomatic (P = 0.029) at study completion, with an accompanying difference in all-cause mortality (17.6% vs. 22.2% respectively, P = 0.523) not reaching statistical significance. Alternatively, 135/191 (84.9%) of Kano patients had selenium deficiency (<70 µg/L), and 46/135 (34.1%) of them received oral selenium supplementation. Critically, those that received selenium supplementation demonstrated better survival (6.5% vs. 21.2%; P = 0.025), but the supplement did not have significant impact on myocardial remodelling. CONCLUSIONS: This study has shown important non-racial regional disparities in the clinical features and outcomes of PPCM patients in Nigeria, that might partly be explained by selenium supplementation.

Selenium supplementation in patients with peripartum cardiomyopathy: a proof-of-concept trial.

BACKGROUND: We studied the efficacy and safety of selenium supplementation in patients who had peripartum cardiomyopathy (PPCM) and selenium deficiency. METHODS: We randomly assigned 100 PPCM patients with left ventricular ejection fraction (LVEF) < 45% and selenium deficiency (< 70 µg/L) to receive either oral Selenium (L-selenomethionine) 200 µg/day for 3 months or nothing, in addition to recommended therapy, in an open-label randomised trial. The primary outcome was a composite of persistence of heart failure (HF) symptoms, unrecovered LV systolic function (LVEF < 55%) or death from any cause. RESULTS: Over a median of 19 months, the primary outcome occurred in 36 of 46 patients (78.3%) in the selenium group and in 43 of 54 patients (79.6%) in the control group (hazard ratio [HR] 0.69; 95% confidence interval [CI] 0.43-1.09; p = 0.113). Persistence of HF symptoms occurred in 18 patients (39.1%) in the selenium group and in 37 patients (68.5%) in the control group (HR 0.53; 95% CI 0.30-0.93; p = 0.006). LVEF < 55% occurred in 33 patients (71.7%) in the selenium group and in 38 patients (70.4%) in the control group (HR 0.91; 95% CI 0.57-1.45; p = 0.944). Death from any cause occurred in 3 patients (6.5%) in the selenium group and in 9 patients (16.7%) in the control group (HR 0.37; 95% CI 0.10-1.37; p = 0.137). CONCLUSIONS: In this study, selenium supplementation did not reduce the risk of the primary outcome, but it significantly reduced HF symptoms, and there was a trend towards a reduction of all-cause mortality.

Impact of using eHealth tools to extend health services to rural areas of Nigeria: protocol for a mixed-method, non-randomised cluster trial.

INTRODUCTION: eHealth solutions that use internet and related technologies to deliver and enhance health services and information are emerging as novel approaches to support healthcare delivery in sub-Saharan Africa. Using digital technology in this way can support cost-effectiveness of care delivery and extend the reach of services to remote locations. Despite the burgeoning literature on eHealth approaches, little is known about the effectiveness of eHealth tools for improving the quality and efficiency of health systems functions or client outcomes in resource-limited countries. eHealth tools including satellite communications are currently being implemented at scale, to extend health services to rural areas of Nigeria, in Ondo and Kano States and the Federal Capital Territory. This paper shares the protocol for a 2-year project ('EXTEND') that aims to evaluate the impact of eHealth tools on health system functions and health outcomes. METHODOLOGY AND ANALYSIS: This multisite, mixed-method evaluation includes a non-randomised, cluster trial design. The study comprises three phases-baseline, midline and endline evaluations-that involve: (1) process evaluation of video training and digitisation of health data interventions; (2) evaluation of contextual influences on the implementation of interventions; and (3) impact evaluation of results of the project. A convergent mixed-method model will be adopted to allow integration of quantitative and qualitative findings to achieve study objectives. Multiple quantitative and qualitative datasets will be repeatedly analysed and triangulated to facilitate better understanding of impact of eHealth tools on health worker knowledge, quality and efficiency of health systems and client outcomes. ETHICS AND DISSEMINATION: Ethics approvals were obtained from the University of Leeds and three States' Ministries of Health in Nigeria. All data collected for this study will be anonymised and reports will not contain information that could identify respondents. Study findings will be presented to Ministries of Health at scientific conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ISRCTN32105372; Pre-results.

Hematological parameters of human immunodeficiency virus positive pregnant women on antiretroviral therapy in Aminu Kano Teaching Hospital Kano, North Western Nigeria.

CONTEXT: Human immunodeficiency virus (HIV) scourge continues to affect young women within the reproductive age group and pregnancy is a recognized indication for the use antiretroviral (ARV) drugs among HIV-positive women. AIMS: The aim is to determine the combined effect of pregnancy, HIV and ARV drugs on the hematological parameters of the pregnant women. SETTINGS AND DESIGN: This was a comparative cross-sectional study conducted among 70 each of HIV-positive and negative pregnant women. SUBJECTS AND METHODS: Bio-demographic and clinical data were extracted from the client folder and 4 ml of blood sample was obtained from each participant. Full blood count was generated using Swelab automatic hematology analyzer while reticulocyte count and erythrocyte sedimentation rate (ESR) were conducted manually. STATISTICAL ANALYSIS USED: Data analysis was performed using SPSS version software 16 while P < 0.05 was considered statistically significant. RESULTS: Pregnant women with HIV had statistically significant lower hematocrit and white blood cell (WBC) and higher ESR than pregnant women without HIV (P < 0.000). There was no statistically significant difference between the two groups in terms of platelet and reticulocyte (P > 0.05). However, among HIV positive pregnant women, those with CD4 count <350/µL had statistically significant lower WBC and lymphocyte count than those with CD4 count ≥350/µL (P < 0.05), whereas, those on zidovudine (AZT)-containing treatment had statistically significant lower hematocrit and higher mean cell volume than those on non-AZT-containing treatment (P < 0.05), but there was no statistically significant difference in any of the hematological parameters (P > 0.050) between women on first- and second-line ARV regimens. CONCLUSIONS: There is a significant difference in terms of hematological parameters between HIV-positive and HIV-negative pregnant women in this environment.

An innovation for improving maternal, newborn and child health (MNCH) service delivery in Jigawa State, northern Nigeria: a qualitative study of stakeholders' perceptions about clinical mentoring.

BACKGROUND: An effective capacity building process for healthcare workers is required for the delivery of quality health care services. Work-based training can be applied for the capacity building of health care workers while causing minimum disruption to service delivery within health facilities. In 2012, clinical mentoring was introduced into the Jigawa State Health System through collaboration between the Jigawa State Ministry of Health and the Partnership for Transforming Health Systems Phase 2 (PATHS2). This study evaluates the perceptions of different stakeholders about clinical mentoring as a strategy for improving maternal, newborn and child health service delivery in Jigawa State, northern Nigeria. METHODS: Interviews were conducted in February 2013 with different stakeholders within Jigawa State in Northern Nigeria. There were semi-structured interviews with 33 mentored health care workers as well as the health facility departmental heads for Obstetrics and Pediatrics in the selected clinical mentoring health facilities. In-depth interviews were also conducted with the clinical mentors and two senior government health officials working within the Jigawa State Ministry of Health. The qualitative data were audio-recorded; transcribed and thematically analysed. RESULTS: The study findings suggest that clinical mentoring improved service delivery within the clinical mentoring health facilities. Significant improvements in the professional capacity of mentored health workers were observed by clinical mentors, heads of departments and the mentored health workers. Best practices were introduced with the support of the clinical mentors such as appropriate baseline investigations for pediatric patients, the use of magnesium sulphate and misoprostol for the management of eclampsia and post-partum hemorrhage respectively. Government health officials indicate that clinical mentoring has led to more emphasis on the need for the provision of better quality health services. CONCLUSION: Stakeholders report that the introduction of clinical mentoring into the Jigawa State health system gave rise to an improved capacity of the mentored health care workers to deliver better quality maternal, newborn and child health services. It is anticipated that with a scale up of clinical mentoring, health outcomes will also significantly improve across northern Nigeria.

Evaluating Health Workers' Knowledge Following the Introduction of Clinical Mentoring in Jigawa State, Northern Nigeria.

Clinical mentoring is work-based training for the capacity building of health care workers. This study determined if there were benefits and increases in knowledge levels for 33 selected health workers across 5 health facilities in Jigawa State following the introduction of clinical mentoring. Questionnaires were used to determine biodata and knowledge scores of mentored health workers and also key departmental activities before and after a 6 months period of introduction of clinical mentoring. Data was analyzed with SPSS version 20. Over 90% of the 33 mentored health workers showed an increase in their knowledge scores. The mean percentage score of the health workers increased significantly from 56.3 ± 2.1 before the start of clinical mentoring to 74.7 ± 1.7 (p < 0.001) six months later. Mortality review meetings were also introduced. This study has shown that clinical mentoring is beneficial for improving the clinical knowledge of mentored health workers.
