Nocturnal Care Interactions with Patients in Critical Care Units

• Background Sleep deprivation is common in critically ill patients and may have long-term effects on health outcomes and patients’ morbidity. Clustering nocturnal care has been recommended to improve patients’ sleep.

• Objectives To (1) examine the frequency, pattern, and types of nocturnal care interactions with patients in 4 critical care units; (2) analyze the relationships among these interactions and patients’ variables (age, sex, acuity) and site of admission to the intensive care unit; and (3) analyze the differences in patterns of nocturnal care activities among the 4 units.

• Methods A randomized retrospective review of the medical records of 50 patients was used to record care activities from 7 PM to 7 AM in 4 critical care units.

• Results Data consisted of interactions during 147 nights. The mean number of care interactions per night was 42.6 (SD 11.3). Interactions were most frequent at midnight and least frequent at 3 AM. Only 9 uninterrupted periods of 2 to 3 hours were available for sleep (6% of 147 nights studied). Frequency of interactions correlated significantly with patients’ acuity scores (r = 0.32, all Ps < .05). A sleep-promoting intervention was documented for only 1 of the 147 nights, and 62% of routine daily baths were provided between 9 PM and 6 AM.

• Conclusions The high frequency of nocturnal care interactions left patients few uninterrupted periods for sleep. Interventions to expand the period around 3 AM when interactions are least common could increase opportunities for sleep.
