RESUMO
OBJECTIVE: The goal of this study was to evaluate the sleep quality and daytime sleepiness of patients eligible for liver transplants. METHODS: A cross-sectional prospective study was conducted on liver transplant candidates from a transplant center in the interior of São Paulo State. The Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale questionnaires were applied to obtain demographic and clinical characteristics and to assess sleep quality and daytime sleepiness. RESULTS: The mean (±SD) score on the Epworth Sleepiness Scale of the 45 liver transplantation candidates was 7.00 ± 2.83 points, with 28.89% having scores >10 points, indicating excessive daytime sleepiness. The mean score on the Pittsburgh Sleep Quality Index was 6.64 ± 4.95 points, with 60% of the subjects showing impaired sleep quality, with scores >5 points. The average sleep duration was 07:16 h. Regarding sleep quality self-classification, 31.11% reported poor or very poor quality. It is noteworthy that 73.33% of patients had to go to the bathroom, 53.33% woke up in the middle of the night, and 40.00% reported pain related to sleeping difficulties. Comparison of subjects with good and poor sleep quality revealed a significant difference in time to sleep (P = .0002), sleep hours (P = .0003), and sleep quality self-classification (P = .000072). CONCLUSION: Liver transplant candidates have a compromised quality of sleep and excessive daytime sleepiness. In clinical practice, we recommend the evaluation and implementation of interventions aimed at improving the sleep and wakefulness cycle, contributing to a better quality of life.
