Effect of Sleep Hygiene Education on Sleep Quality in Patients With Liver Transplantation.

This study aimed to determine the effects of sleep hygiene education on sleep quality in liver transplant patients. In the literature, the efficacy of various pharmacological methods for reducing poor sleep quality associated with liver transplant patients and studies on nonpharmacological methods are limited. This study was conducted using a quasiexperimental design with a pre- and posttest, and a control group. When the power analysis was made, a sample size with 5% double-sided significance, 95% confidence interval, and 95% ability to represent the population was calculated to have a total of 100 liver transplant patients. The data were collected using a patient information form, and the Richard Campbell Sleep Quality Questionnaire. In the experimental group, the researcher gave a sleep hygiene training for 1 week. No treatment was performed in the control group. To analyze the data, descriptive statistics, a χ2 test, a t test for dependent groups, and a t test for independent groups were used. According to sleep hygiene training follow-ups after liver transplantation, the mean scores of sleep quality was similarly poor, with a statistical significance in the experimental group compared with the control group in all measurements before and after sleep hygiene training (P < .001). The sleep hygiene training applied to liver transplant patients positively affected and decreased the severity of sleep quality.
