RESUMEN
BACKGROUND: An increase in infant drops on a postpartum unit prompted a quality improvement project to examine causes and formulate risk reduction strategies. Review of health records revealed that infant drops occurred more frequently when mothers fell asleep holding infants. METHODS: A prospective descriptive study was conducted with a convenience sample of 101 postpartum mother-infant dyads. Hourly assessments of maternal sleepiness using the Stanford Sleepiness Scale (SSS) and surveillance of patient rooms were performed during hospitalizations (N = 4,550 observations). RESULTS: Mothers slept on average 3.7 hours/day (median = 5.0). Sleepiness followed an expected nighttime routine on postpartum day 1 regardless of when mothers arrived on the unit. Peak sleepiness was observed at 04:00 (mean SSS score = 5.3; standard deviation [SD] = 2.6), and mothers were most awake until 18:00 (mean SSS score = 1.9; SD = 1.7). No infant drops occurred during the project; however, 50 participants required at least one intervention or corrective action to address unsafe sleep. Of 1,718 observations of mothers in bed with their infant, there were 35 instances (2.0%) where nurses observed mothers asleep holding their infant. CONCLUSION: Frequent observations of maternal sleepiness and infant environments may prevent infant drops and provide opportunities for intervening with risk reduction strategies, including education on safe sleep for infants.
