SLEEP QUALITY ASSESSMENT OF PATIENTS IN A CARDIOLOGICAL INTENSIVE CARE UNITY

Introdução

The quality of sleep is directly related to the preservation of its architecture. An imbalace in this process may directly affect homeostasis, interfering in the Autonomic Nervous System, provoking blood pressure and heart rate alteration. Hospitalized patients in Intensive Care Units (ICU) are more likely to have sleep deprivation due to the severity of their condition, pharmacological treatments and exposition to environmental factors. Heart diseased patients show higher vulnerabilty because sleep quality is related to triggering factors of cardiac alterations.

Objetivo

Assess sleep quality of heart diseased patients hospitalized in a cardiological ICU.

Métodos

This is a cross-sectional study made with hospitalized patients in a cardiological ICU of a public hospital in the city of Salvador (BA). Were involved in this study patients of both genders, over 18 years old, lucid, colaborative and that were at least in their second day of hospitalization. Were ruled out patients with cognitive and hearing limitations, unable to answer the questionaires and the ones that refused to take part in the study. Were applied the Pittsburgh Sleep Quality Index (PSQI), Richards-Campbell Sleep Questionnaire (RCSQ) and the Sleep in the Intensive Care Unit Questionnaire (QS-ICU) by researchers trained in the period of July to October 2023.

Resultados

33 patients took part in the research, being 55,0% males. The medium age of the participants were of 60,3 ± 12,9 years. In addition to environmental factors, sleep habits pre-hospitalization in the ICU influenced the sleep quality during hospitalization, with 73,0% of the patients already exhibiting poor subject sleep quality before hospitalization. In the PSQI it stood out major impact of sleep latency and night sleep disturbances. Via the QSRC, it was observed that the most important factors that have an effect on sleep quality were the amount of sleep depth and time to sleep, awakening and background noise. Considering the QS-ICU, the noise showed greater impact in sleep interruption in comparison to luminosity, conversations and team activities, with emphasis on the noise from the monitors.

Conclusões

Sleep quality of patients hospitalized in a cardiological ICU is low due to the time required to fall asleep, sleep fragmentation and noise from the unit. The patients' sleep quality previous to hospitalization may be an associated relevant factor. Environmental aspects must be considered.
