The effect of audiobooks on sleep quality and vital signs in intensive care patients.

OBJECTIVE

Improving sleep quality in the intensive care unit is significant for the recovery process. This study investigated the effect of listening to audiobooks on sleep quality and vital signs in intensive care patients.

METHODS

This quasi-experimental study utilized the pre-posttest design, involving control and intervention groups. The study was conducted in the internal medicine intensive care unit of a hospital in Turkey between January-June 2022. Standard nursing care was given to both groups on the first night, and the Sleep Evaluation Form and Richard Campbell Sleep Scale were used to measure sleep quality in the morning. On the second day, the intervention group listened to a recorded story, and the control group had standard care. Sleep quality and vital signs were measured again.

RESULTS

Data from 56 participants were analyzed. Noise (96.4%), light (69.6%), unfamiliar environment (64.8%), concerns about illness (33.9%), and care and treatments (58.9%) are the main causes of sleep disruption. The effect of these factors decreased in the intervention group after the Audiobook Listening Practice, which significantly improved the sleep quality of the ICU patients (p < 0.001). Among the vital signs, a significant difference was found in pulse and blood pressure (p < 0.001), while no changes were observed in temperature and respiratory rate in time group interaction (p > 0.05).

CONCLUSIONS

The Audiobook Listening Practice improved sleep quality and life parameters in the ICU. Nurses can use the practice to improve sleep quality in intensive care units.

IMPLICATIONS FOR CLINICAL PRACTICE

Evidence-based studies are needed to improve the sleep quality of patients in intensive care units, to ensure clinical improvement, and to reduce the length of stay at hospital. The practice is effective in manipulating environmental stressors. This low-cost method significantly improves patient care activities. It is recommended to integrate such complementary activities into intensive care units, to train nurses about the practice, and to support the practice with new studies.
