Decision-to-delivery interval of emergency cesarean section in Uganda: a retrospective cohort study

Table 4 Outcomes of delivery

Delivery outcome	Number (%)	Influence of decision-to-delivery interval	Influence of decision time	Influence of delivery time
Adverse maternal outcome	16 (4.7%)	p = 0.26	p = 0.61	p = 0.54
Fresh stillbirth	13 (3.8%)	p = 0.15	p = 0.16	p = 0.07
Neonatal death	21 (6.4%)	p = 0.85	p < 0.05*	p = 0.07
Perinatal death	35 (10.2%)	p = 0.68	p < 0.01**	p < 0.05*
Admission to the Special Care Baby Unit	78 (23.6%)	p = 0.75	p = 0.59	p = 0.53
APGAR < 7 at 1 min	76 (23.0%)	p = 0.57	p = 0.16	p = 0.47
APGAR < 7 at 5 mins	77 (23.3%)	p = 0.56	p = 0.13	p = 0.39
Other adverse neonatal outcome	47 (14.2%)	p = 0.24	p < 0.05*	p < 0.05*

The number of mothers who experienced each adverse outcome is shown along with the percentage. For outcomes that can apply to all deliveries (perinatal death, stillbirth, adverse maternal outcomes) the total was n = 344. For outcomes that apply only to live born infants, the total was n = 330. More than one adverse outcome was present in some cases. The influence of decision-to-delivery interval is represented by p-values derived from logistic regression models, in which the risk of outcome is conditioned upon the length of the interval in hours. The influence of decision time and delivery time are the p-values derived from generalised additive models with a non-parametric effect for the time of day at decision and delivery respectively. All models were adjusted for the sex and gestational age-specific centile of the neonate’s birth weight. *p < 0.05, **p < 0.01
