Performance of Integrated Emergency Surgical Officers at Mizan-Tepi University Teaching Hospital, Mizan-Aman, Ethiopia: A Retrospective Cohort Study

Table 2

(A) Multivariable model of characteristics associated with IESO attendant and (B) how outcomes are impacted by delivery by IESO as compared to midwife attendant.

Characteristic	RR	CI	-value
(A) Multivariable poisson model with robust error variance of characteristics associated with IESO as attendanta
Mode of delivery (unassisted vaginal birth reference)
Forceps-assisted	88.4	28.7, 271.7	<0.001
Vacuum-assisted	45.2	14.3, 142.3	<0.001
Cesarean	161.8	59.9, 437.2	<0.001
(B) Individual logistic regressions, adjusted for significant findings in Table 4, to determine association of cesarean birth with outcomes significant in bivariate comparisons (Table 3)
Maternal outcomes^b
Odds of postpartum hemorrhage	Model did not converge
Odds of needing postpartum antibiotics	13.4	3.0, 60.2	0.001
Odds of longer hospitalization	Model did not converge
Neonatal outcomes^b
Odds of having a higher apgar score	0.1	0.1, 0.7	0.02
Odds of live birth	0.2	0.1, 1.3	0.09
Odds of being alive at discharge from the hospital	0.1	0.1, 0.5	0.005
Odds of longer neonatal hospitalization	0.2	0.1, 2.1	0.18

^aVariables included in the model without an association with the outcome: urban/rural residence, parity, history of cesarean birth, HIV status, onset of labor (spontaneous or not), duration of labor, antepartum hemorrhage, birthweight, and multiple gestation. ^bAdjusted for mode of delivery.
