Factors That Contribute to Excessive Sleepiness in Midwives Practicing in the United States

Excessive daytime sleepiness is defined as difficulty maintaining wakefulness and alertness during normal waking hours. Excessive daytime sleepiness can lead to clinical errors in health care workers and is associated with dangerous driving. Little is known about the level of daytime sleepiness in midwives in the United States. The purposes of this study, conducted by the American College of Nurse-Midwives (ACNM) Sleep and Safety Taskforce, were first to identify the sleepiness level of US certified nurse-midwives (CNMs) and certified midwives (CMs) by calculating Epworth Sleepiness Scale scores for CNM/CMs in full-scope practice, and then to determine factors that significantly contribute to elevated Epworth Sleepiness Scale scores (>10).

Participants in this descriptive, correlational survey study were active ACNM members in full-scope midwifery practice. Descriptive statistics, bivariate analysis, and logistic regression were used for data analysis. Surveys were emailed to all active members of ACNM (N = 4358).

A total of 753 (17.3%) survey responses were returned, of which 639 (14.7%) were eligible for analysis. Within this group, 639 (84.9%) self-identified as being in full-scope midwifery practice, and one-fourth (n = 164; 25.7%) had elevated Epworth Sleepiness Scale scores. Duration of work shifts was the only variable found to significantly contribute to differences in Epworth Sleepiness Scale scores, with midwives working shifts longer than 12 hours having higher rates of excessive daytime sleepiness compared with midwives who worked shifts of 12 hours or less.

Midwives, midwifery services, and maternity care centers can work together to ensure that clinicians obtain adequate sleep. Reducing excessive sleepiness will contribute to increased safety for midwives, women, newborns, and the general public.
