Abstract :
Background: The etiology of sleep disruption in
intensive care unit is poorly known and often ignored
complication. It is caused by the environmental factors
especially pain, noise, diagnostic testing and human
interventions that cause sleep disruption. Light,
medications and activities related to patient care
interfere with patient’s ability to have good sleep.
There are multi-factorial environmental etiologies for
disruption of sleep in ICU.
Objective: The objective of this study was to evaluate
the factors disturbing the sleep quality in intensive
care unit (ICU) admitted patients.
Methodology: A cross sectional study was designed
involving 150 patients admitted in intensive care unit
and high dependency unit of Gulab Devi Chest
Hospital. The duration of study was from September
2015 to March 2016. The questionnaire was made and
filled with the help of patients. The data was analyzed
using SPSS version 16.00.
Results: Mean age of patients was 50.46+10.96 with
maximum age of 65 and minimum age of 30 years.
There was 53.33% male patients and 46.67% females
participating in this study. The sleep quality was
significantly poor in ICU than at home. After analysis,
54.67% patients were with poor quality of sleep due to
pain and 48.67% were due to noise of environmental
stimuli. The other factors were alarms, light and loud
talking.
Conclusion: Current study shows that reduced sleep
quality is a common problem in ICU with multifactorial
etiologies. Patient reported the poor sleep
quality in ICU due to environmental issues that are
potentially modifiable.
