Abstract
BACKGROUND: Globally, the quality of maternal and newborn care remains inadequate, as seen through indicators like perineal injuries and low Apgar scores. While midwifery practices have the potential to improve care quality and health outcomes, there is a lack of evidence on how midwife-led initiatives, particularly those aimed at improving the use of dynamic birth positions, intrapartum support, and perineal protection, affect these outcomes. OBJECTIVE: To explore how the use of dynamic birth positions, intrapartum support, and perineal protection impact the incidence of perineal injuries and the 5-min Apgar score within the context of a midwife-led quality improvement intervention. METHODS: A cohort of 630 women with uncomplicated full-term pregnancies was recruited from a hospital in Uganda. Observations and questionnaires assessed birth positions, intrapartum support, perineal protection, health outcomes and maternal characteristics. Primary outcomes included perineal injuries and the 5-min Apgar scores. The primary outcomes were analysed using descriptive data, with trends visualised through a run chart to assess changes during the midwife-led Quality Improvement intervention. Secondary outcomes included postpartum haemorrhage, admission to neonatal intensive care, newborn resuscitation, skin-to-skin care, and breastfeeding initiation. RESULT: A statistically significant association was found between women having intact perineum (i.e., no perineal injuries) and giving birth in a dynamic birth position [AOR; 0.6 (95% CI 0.4 - 0.90)], receiving intrapartum support [AOR; 0.9 (95% CI 0.9 - 1.0)], and using perineal protection measures [AOR; 0.3 (95% CI 0.2 - 0.5)]. Newborns with an Apgar score below seven at five minutes were significantly associated with intrapartum support [AOR; 0.8 (95% CI 0.7 - 1.0)] and perineal protection [AOR; 0.3 (95% CI 0.1 - 0.8)]. However, after adjustment, no significant association was found between Apgar score and birth positions [AOR; 0.5 (95% CI 0.2 - 1.5)]. Perineal injuries and low Apgar scores significantly decreased (p < 0.001) during the Midwife-led Quality Improvement intervention period. CONCLUSION: This study demonstrates that low 5-min Apgar scores and perineal injuries decreased during a midwife-led Quality Improvement intervention focusing on dynamic birth positions, intrapartum support, and perineal protection strategies. CLINICAL TRIAL: This study is registered on ClinicalTrials.gov as of 14th February 2022, under registration number NCT05237375.
