Effects of an earplug placement intervention on sleep quality in patients in a medical intensive care unit: A randomized controlled trial.

Aims: This study aimed to evaluate the effects of an intervention involving earplug placement during nocturnal sleep in non-ventilated intensive care unit patients.

Methods: A randomized controlled trial was conducted in 107 adult patients between January 2017 and December 2018. Participants in the intervention group (n = 55) slept with earplugs between 10 pm and 7 am on the second night of their intensive care unit stay.
