“…The ICU is known to contribute to poor sleep; such sleeplessness increases the risk of delirium 47. By enacting a series of nonpharmacologic interventions (closing doors, decreased alarm volumes, ear plugs, eye masks, and timed “lights off”) to improve sleep in the ICU, Patel et al were able to reduce the incidence of delirium compared with the nonintervention arm (33% versus 14%, P <0.001) 48.…”

“…The total number of hours of sleep in 24 hours may be normal, yet 50% of sleep occurs during the daytime in short bouts. This results in increased sleep onset latency, rapid eye movement latency, increased fraction of wakefulness, and stage 1 sleep [6]. …”

Background: Insomnia is common in hospitalized patients. However, no study has examined new onset of insomnia in patients without a prior history of insomnia. Objectives: Incidence of new onset of insomnia in inpatients, associated factors and resolution rate after 2 weeks. Method: This is a prospective observational study conducted at a community hospital. We used the Insomnia Severity Index questionnaire to screen for insomnia in all patients located in the general medical floors from day 3 to day 5 of their hospital stay. We excluded patients with a prior insomnia history. Results: Out of the 205 patients who met the inclusion criteria, 75 patients (36%) reported insomnia. Severe insomnia was present in 3% of patients. Difficulty in maintaining sleep is the most common symptom. Frequent staff disruptions due to blood draws and vital signs checks were reported by 68% as the cause of insomnia, followed by illness associated causes (64%) and sleep disruption due to noise and or brightness (23%). Patients with insomnia had more awakenings due to noise, brightness, and staff interruptions than those without insomnia (1.35 times vs. 0.9 times, p = 0.027). Patients with respiratory symptoms, cardiac monitoring, oxygen use, private rooms, and no sedative use did not have a higher insomnia risk. Patients with insomnia had significant lower satisfaction scores than patients without insomnia (4.53 vs. 4.05, p = 0.001) but did not have a different length of stay (6.18 vs. 6.19, p = 0.97). In 31% of patients with insomnia who were able to be contacted two weeks after discharge, 75% of them had insomnia resolution. Conclusion: New onset of insomnia occurred in 36% of hospitalized patients. Most common causes are staff disruption and disease symptoms. It was usually short-term and could decrease patients’ satisfaction score.

“…Sleep is an indispensable need for the recovery of hospitalized patients (1,2). Patients admitted to the intensive care unit (ICU), who are usually critically ill patients, need more sleep, however, they are at a higher risk for sleep deprivation, poor sleep quality, and disturbed sleep-wake cycle (3,4).…”
