Background: Healthcare checklists are cognitive aids that can be referenced by clinicians to reduce medical errors and reduce deviation from established treatment protocols. Objective: To review published checklists for eclampsia, amniotic fluid embolism, uterine inversion, and magnesium toxicity, compare key components of the checklists, and develop consensus that could be used for future checklist development. Study Design: Systematic review Selection Criteria: All studies that contained a detailed checklist with specific actions related to rare obstetric emergencies were included. Rare obstetric emergencies were defined as having an estimated incidence less than 1 in 10,000. The literature search focused on amniotic fluid embolism, uterine inversion, eclampsia, and magnesium toxicity. Studies that only contained lists of medications, supplies, or data collection sheets were excluded. Data Collection and Analysis: Two authors independently extracted data from each included study and conflicts were resolved by a senior author. Main results: There were 15 included publications, with a total of 24 emergency checklists reviewed. Conclusion: There is large variation in the recommended clinical steps for checklists on rare obstetric outcomes. This comparison will aid clinicians and organizations who would develop an institution-specific checklist for amniotic fluid embolism, uterine inversion, eclampsia, and magnesium toxicity.
