Racial and ethnic differences in access to and outcomes of elective induction of labor in low-risk pregnancies: a scoping review

Abstract

Purpose

Elective induction of labor (IOL) has been increasingly performed since growing data suggesting its safety and potential improved maternal and neonatal outcomes. Recommendations of elective IOL for patients from racial or ethnic minority backgrounds given the data showing increased risk of stillbirth for some populations has been met with criticism. This scoping review aims to determine if there are racial disparities in access to elective IOL and maternal and neonatal outcomes.

Methods

A review of the literature on IOL that appeared in English journals was performed using MEDLINE and EMBASE. The search strategy included the combination of key terms “induction of labour” and “race” or “ethnicity” in titles, abstracts, or keywords.

Results

A total of 8 studies were identified and included. The articles were heterogenous in the race or ethnicity distinctions they used for analysis. Three out of 4 studies that analyzed the rate of elective IOL by race found that White patients were more likely to receive the intervention. Three out of 4 studies that analyzed outcomes of IOL found no difference, while one study found Black patients benefit most from IOL at 38 weeks compared to other races that had the lowest risk of complications with IOL at 39 weeks.

Conclusion

Racial and ethnic disparities exist with White patients being most likely to access this intervention. The majority of data points to similar outcomes, suggesting no increased harm to elective IOL for a particular group. However, the optimal timing of elective IOL given disproportionate stillbirth risk remains to be elucidated.
