Objective This study aimed to compare the use of the Turkish versions of the Glasgow Coma Scale (GCS) and Full Outline of UnResponsiveness (FOUR) Score by intensive care nurses in neurological evaluation. Materials and Methods This cross‐sectional study was conducted between July 2018 and March 2019 with 92 patients in the general intensive care unit (ICU) of the training and research hospital of a private university. Data were collected using nurse and patient information forms, the GCS and the FOUR Score. The patients were evaluated by 27 intensive care nurses. To evaluate interrater reliability of the GCS and FOUR Score, each patient in the study was evaluated using both scales by two nurses who were blinded to each other’s responses. Results Comparison of the patients’ mean GCS and FOUR Score values from the two nurses revealed no significant difference in subscale or total scores (p > 0.05). Evaluation of interrater reliability demonstrated very good agreement (κ = 0.935, p < 0.001). There was also very good agreement between the results of the two nurse groups when the patients’ total scores were categorised according to the cut‐off points for the two instruments (κ = 0.927, p < 0.001). Conclusion This study demonstrated excellent agreement in the Turkish GCS and FOUR Score values, indicating that both scales can be used in neurological evaluation. Both instruments are reliable and easily applied by ICU nurses. Relevance to Clinical Practice The Turkish versions of the FOUR Score and GCS are both appropriate for use in intensive care units and are reliable tools for use by intensive care unit nurses.

This study was conducted to evaluate the relationship between sleep quality and environmental stressors perceived by patients in the intensive care unit. The study was a descriptive, cross-sectional, and correlational study. Data were collected from 175 patients in the intensive care unit between April and December 2021. The mean age of the patients included in the study was 64.7 ± 12.50 years, and the duration of treatment in the intensive care unit was 2.68 ± 0.85 days. The mean score of the Richard-Campbell Sleep Questionnaire was 37.01 ± 17.84, and Intensive Care Unit Environmental Stressors Scale was 131.63 ± 19.18. There was a statically significant negative correlation between The Richard-Campbell Sleep Questionnaire score with the duration of therapy in the intensive care unit (p < 0.001), pain (p < 0.001), and fatigue (p < 0.001). A negative statistically significant correlation was seen between the Intensive Care Unit Environmental Stressors Scale and the Richard-Campbell Sleep Questionnaire (p < 0.001). As a result of this study, the sleep quality of patients in the intensive care unit was found to be affected by environmental stressors. In addition, fatigue and pain were found to have an effect on sleep quality, and environmental factors also affected patients' waking status in the intensive care unit.
