Impact of ‘decision-to-delivery’ interval on maternal and perinatal outcomes: a retrospective study of emergency caesarean section from 2017 to 2021 at a secondary health facility in Nigeria

Abstract

Background The decision-to-delivery interval (DDI) for a caesarean section is among the factors that reflect the quality of care a pregnant woman receives and the impact on maternal and foetal outcomes and should not exceed 30 min especially for Category 1 National Institute for Health and Care Excellence (NICE) guidelines. Herein, we evaluated the effect of decision-to-delivery interval on the maternal and perinatal outcomes among emergency caesarean deliveries at a secondary health facility in north-central Nigeria. Methods We conducted a four-year retrospective descriptive analysis of all emergency caesarean sections at a secondary health facility in north-central Nigeria. We included pregnant mothers who had emergency caesarean delivery at the study site from February 10, 2017, to February 9, 2021. Results Out of 582 who underwent an emergency caesarean section, 550 (94.5%) had a delayed decision-to-delivery interval. The factors associated with delayed decision-to-delivery interval included educational levels (both parents), maternal occupation, and booking status. The delayed decision-to-delivery interval was associated with an increase in perinatal deaths with an odds ratio (OR) of 6.9 (95% CI, 3.166 to 15.040), and increased odds of Special Care Baby Unit (SCBU) admissions (OR 9.8, 95% CI 2.417 to 39.333). Among the maternal outcomes, delayed decision-to-delivery interval was associated with increased odds of sepsis (OR 4.2, 95% CI 1.960 to 8.933), hypotension (OR 3.8, 95% 1.626 TO 9.035), and cardiac arrest (OR 19.5, 95% CI 4.634 to 82.059). Conclusion This study shows a very low optimum DDI, which was associated with educational levels, maternal occupation, and booking status. The delayed DDI increased the odds of perinatal deaths, SCBU admission, and maternal-related complications.
