This study has been planned as a randomized controlled clinical trial and will use a 2x2 factor design in which an equal number of participants meeting the inclusion criteria will be randomly allocated to one of four groups. The study population will comprise 120 adult patients who have undergone ostomy surgery in a city hospital in Turkey. Lavender oil inhalation together with sleep hygiene education will be applied in the first group (n=30), only sleep hygiene education in the second group (n=30), only lavender oil inhalation in the third group (n=30), and no intervention in the fourth group (n=30). The sleep quality of the groups will be evaluated using the Pittsburgh Sleep Quality Index, their fatigue levels with the Chalder Fatigue Scale, and their quality of life with the Stoma Quality of Life Scale.
Self-care non-pharmacological methods can help reduce the negative health effects of sleep problems or insomnia. This trial aims to investigate the effects of sleep hygiene education and lavender oil inhalation alone and in combination on sleep quality, fatigue, and health-related quality of life in adults with a stoma.
