As the old adage says, “practice makes perfect” and AIM OBH teams have operationalized those wise words. AIM OBH teams structure simulation practice and drills around OBH differently throughout the course of the competency year but nearly all teams have conducted some type of drill over the initiative. In the third quarter of 2017, teams ran a total of 154 drills covering not only identification and management of OBH but also topics such as shoulder dystocia, stat Cesarean section, malignant hyperthermia, maternal code blue, and emergent maternal transfer to name a few. In the fourth quarter of 2017, teams conducted a total of 112 drills and in the first quarter of 2018, a total of 133 drills were run. The frequency of drills varies on each team with some teams scheduling drills once a quarter and others once a year but all teams have practiced and enhanced their skills in identification and management of OBH.
