Purpose: Even if the prerequisites and the technique of vacuum extraction are largely established, the role of a checklist in this field has not been tested. To evaluate the role of a checklist implementation on the compliance with the recommended rules in operative vacuum vaginal delivery (OVD) and on maternal and perinatal outcomes.

Materials And Methods: Retrospective cohort study on OVD between January 2012 and December 2015 at two hospitals with a tradition of teaching of OVD. A checklist for OVD was introduced in 2014. Three rules had to be recorded: fetal head station and position determination, no more than four tractions, and no more than three cup applications. Adverse maternal outcomes included third- and fourth-degree perineal tears. Adverse neonatal outcome included asphyxia, need for neonatal resuscitation, NICU admission, major head injuries, scalp injuries, and bone or brachial plexus injuries.

Results: Introduction of a checklist for OVD resulted in an increase in the compliance with the rules (83.3 versus 62.8%,  < .001). Cases in which the rules were respected had lower incidence of third- and fourth-degree perineal lacerations after controlling for episiotomy, nulliparity, and indication for OVD (OR = 0.4, 95% CI 0.18-0.89), but similar rates of failure of OVD (2.1 versus 2.2%,  = 1) and adverse neonatal outcome (10.8 versus 11.7%, =.71).

Conclusion: Knowledge and documented compliance with a checklist of recommended rules in OVD may assist in achieving a lower rate of severe perineal and anal sphincter injury but does not alter the success of the procedure or neonatal outcome.
