Association of Insomnia in Patients with Chronic Kidney Disease on Maintenance Hemodialysis

Objective To determine the frequency of insomnia in patients with chronic kidney disease (CKD) on maintenance hemodialysis (HD) Study design Cross-sectional (descriptive) Study duration From July 20, 2019, to January 20, 2020 Study settings Department of Nephrology, Khyber Teaching Hospital, Peshawar Materials and methods A total of 148 patients diagnosed with CKD and on maintenance HD were selected for the study in a consecutive sampling manner and checked for insomnia. Results Out of 148 patients included in the study, there were 64.9% male and 35.1% female patients. The mean duration of CKD (months) was 13.9 ± 6.3. The mean number of sessions for hemodialysis done in all patients was 16.8 ± 5.3. On careful interviewing of the patient, difficulty in falling asleep was recorded in 28.4%, difficulty in staying asleep in 41.9%, problems in waking up early in 34.5%, and insomnia interfering in routine life activities in 28.4%. Overall, insomnia was recorded in 36.5% of patients and was found to have a significant correlation with the number of dialysis sessions (p-value 0.000). Conclusion Insomnia is a frequent disorder associated with CKD patients on maintenance HD. There are very few studies establishing its pathogenesis and risk factors. We recommend further multicenter studies to detect the course of insomnia in association with CKD on HD and its potential impact on the overall quality of life of patients with CKD.
