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.

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.

Peritoneal adhesion findings during laparoscopy: Determinants of occurrence and effect of severity on operative outcomes in a Nigerian Hospital.

Context: Peritoneal adhesions unlike other immediately recognizable complications of the surgery may produce long-term consequences, which include infertility and intestinal obstruction. Aims: The study aimed to determine the prevalence, the determinants, and the outcomes of laparoscopic surgery associated with intraperitoneal adhesion findings. Settings and Design: This was a retrospective observational study. Materials and Methods: The study included all laparoscopic gynecological surgeries done between January 2017 and December 2021. Adhesion severity was graded, using the peritoneal adhesion index (PAI), by Coccolini et al. Statistical Analysis: The data were analyzed using the SPSS version 21.0. Binary logistic regression was used to assess the factors associated with adhesion finding during laparoscopy. Results: There were 158 laparoscopic surgeries with 26.6% prevalence of peritoneal adhesions. The prevalence of adhesions among women with previous surgery was 72.7%. Previous peritoneal surgery was a significant determinant of occurrence of adhesions (odds ratio = 8.291, 95% confidence interval [CI] = 4.464-15.397, P < 0.001), and such patients had significantly (P = 0.025, 95% CI = 0.408-5.704) more severe adhesions (PAI = 11.16 ± 3.94) than those without prior surgery (PAI = 8.10 ± 3.14). Abdominal myomectomy (PAI = 13.09 ± 2.95) was the most important primary surgical determinant of adhesion formation. There was no significant relationship between adhesion occurrence and conversion to laparotomy (P = 0.121) or mean duration of surgery (P = 0.962). Greater adhesion severity was, however, observed in individuals with operative blood loss <100 ml (PAI = 11.73 ± 3.56, P = 0.003) and those hospitalized for ≤2 days (PAI = 11.12 ± 3.81, P = 0.022). Conclusion: The prevalence of postoperative adhesions during laparoscopy in our center is comparable to what has been earlier reported. Abdominal myomectomy is associated with the greatest risk and severity of adhesions. Laparoscopy in patients with more severe adhesions resulted in less blood loss and shorter duration of hospitalization, suggesting an association of better outcomes with a cautious approach to adhesions.

Résumé Contexte: Les adhérences péritonéales, contrairement aux autres complications chirurgicales immédiatement reconnaissables, peuvent avoir des conséquences à long terme, notamment la stérilité et l'occlusion intestinale. Objectifs: L'étude visait à déterminer la prévalence, les déterminants et les résultats de la chirurgie laparoscopique associée aux résultats des adhérences intrapéritonéales. Paramètres et conception: Il s'agissait d'une étude d'observation rétrospective. Matériaux et méthodes: L'étude a inclus toutes les chirurgies gynécologiques laparoscopiques réalisées entre janvier 2017 et décembre 2021.La gravité des adhérences a été évaluée, en utilisant l'indice d'adhérence péritonéale (PAI), de Coccolini et al. Analyse statistique: Les données ont été analysées à l'aide de SPSS version 21.0. Une régression logistique binaire a été utilisée pour évaluer les facteurs associés à la recherche d'adhérences pendant la laparoscopie. Résultats: Il y a eu 158 chirurgies laparoscopiques avec une prévalence de 26,6 % d'adhérences péritonéales. La prévalence des adhérences chez les femmes avec une chirurgie antérieure était de 72,7 %. La chirurgie péritonéale antérieure était un déterminant important de l'apparition d'adhérences (rapport de cotes = 8,291, Intervalle de confiance [IC] à 95 % = 4,464-15,397, P < 0, 001), et ces patientes avaient significativement (P = 0,025, IC à 95 % = 0,408-5,704) des adhérences plus sévères (PAI = 11,16 ± 3,94) que celles sans chirurgie préalable (PAI = 8,10 ± 3,14). La myomectomie abdominale (PAI = 13,09 ± 2,95) était le déterminant chirurgical primaire le plus important de la formation de l'adhérence. Il n'y avait pas de relation significative entre l'occurrence de l'adhérence et la conversion en laparotomie (P = 0,121) ou la durée moyenne de la chirurgie (P = 0,962). Cependant, une plus grande sévérité de l'adhérence a été observée chez les personnes ayant une perte de sang opératoire <100 ml (PAI = 11,73 ± 3,56, P = 0,003) et celles hospitalisées pendant ≤2 jours (PAI = 11,12 ± 3,81,P=0,022). Conclusion: La prévalence des adhérences postopératoires lors d'une laparoscopie dans notre centre est comparable à ce qui a été précédemmentRapporté. La myomectomie abdominale est associée au plus grand risque et à la plus grande sévérité des adhérences. La laparoscopie chez les patients souffrant d'adhérences plus sévères a entraîné une perte de sang moins importante et un séjour hospitalier plus court, ce qui suggère une association de meilleurs résultats avec une approche prudente des adhérences.
