Depression Among Hemodialysis Patients: Related Factors and the Impact of Insomnia and Fatigue

Abstract

Introduction: Depression is a commonly experienced psychological disorder among patients undergoing hemodialysis and has a strong association with insomnia and fatigue. The purpose of the present study was to explore the factors related to depression in dialysis patients and the impact of insomnia and fatigue on depression. Methods: In this cross-sectional study, one hundred (n=100) patients on hemodialysis from one hemodialysis center in Greece participated. Data collection was carried out by interviews using the Zung Self-rating Depression Scale (SDS) for the evaluation of depression; the Athens Insomnia Scale (AIS) for the evaluation of insomnia; the Modified Fatigue Impact Scale (MFIS) for the evaluation of fatigue; and a questionnaire which was created by the researchers. The Kruskal-Wallis, the Mann-Whitney tests, and the Spearman's rho criterion were used to evaluate the relationship between depression score and patient characteristics. Multiple linear regression was performed to assess the effect of characteristics on patients' depression. Results: Statistically significantly high levels of depression were found in patients over the age of 70 years old (p=0.001), in divorced/widowed patients (p = 0.001), in pensioners (p = 0.002), in patients who had other diseases (p = 0.001), in those who felt tired after hemodialysis or at night and those who felt constantly tired (p = 0.001, p = 0.016, and p = 0.001, respectively), in those who had physical and mental fatigue (p = 0.001 and p = 0.001, respectively), in those who had changes in body image (p = 0.009), itching, stiffness, and nausea/vomiting (p = 0.001, p = 0.001, and p = 0.003, respectively), in patients who had restrictions in clothes they could wear (p = 0.001), in patients who had insomnia (p = 0.001), and in patients who did not wish to receive written information about the management of their disease (p = 0.025). A statistically significant positive linear association was detected between physical/mental fatigue and depression levels (rho = 0.824 and rho = 0.746, respectively) and between the score of insomnia and depression levels (rho = 0.707). An increase in fatigue (either physical or mental) and an increase in insomnia score also indicated an increase in depression levels. Conclusions: The findings of this study showed that depression had a strong association with a variety of demographic factors. Additionally, an increase in fatigue score and an increase in insomnia score indicated an increase in depression levels. Therefore, depression, insomnia, and fatigue should be early assessed and effectively treated by renal professionals in order to improve the quality of life in hemodialysis patients and reduce their morbidity and mortality.

Hemodiyaliz Tedavisi Alan Bireylerde Stigmaya Neden Olan Semptomlar ve Yönetimi

“…Ayrıca günlük yaşamda fonksiyonel ve beslenme kısıtlamaları, ilaç yan etkileri, sosyal desteğinin olmaması ve sağlık çalışanlarına bağımlılık depresyona yol açmaktadır. Hemodiyaliz tedavisi alan bireylerle yapılan bir çalışmada, depresyonun yaygın olarak görüldüğünü, uykusuzluk ve yorgunluk ile ilişki olduğu ifade edilmiştir (34). Benzer bir çalışmada ise katılımcıların çoğunlukla hastalıktan sonra ağır psikososyal problemlerle karşılaştıkları belirtilmiştir (35).…”

“…Bireylerde sık uyanma, uykuya dalmada gecikme, gündüz uyuklama, huzursuz bacak sendromu sık görülen uyku sorunlarındandır (36). Bu nedenle, depresyon, uykusuzluk ve yorgunluk erken dönemde değerlendirilmeli ve bu kişilerin yaşam kalitesini arttırmak, hastalık ve ölüm oranlarını azaltmak için etkili bir tedavi planı oluşturulmalıdır (34).…”
