Quality of Sleep in Patients With Chronic Rhinosinusitis at Kenyatta National Hospital

Abstract

Background: Chronic rhinosinusitis (CRS) is a frequent rhinological disease. Among individuals suffering from it, a common complaint is poor sleep, which can lead to morbidity and mortality. Objective: To determine the quality of sleep in patients with CRS at Kenyatta National Hospital. Study Methodology: This was a hospital-based descriptive cross-sectional study. Recruitment was via convenience sampling. It involved adults (≥18 years) with a diagnosis of CRS on follow-up at the Kenyatta National Hospital-Ear, Nose, and Throat clinic. Informed consent was obtained, followed by a history and physical examination. Patients who did not have paranasal sinus computed tomography imaging had nasal endoscopy done. After that, the CRS visual analogue scale, the Pittsburgh sleepiness scale, and the Epworth sleepiness scale questionnaires were completed. Study Analysis: The results were analysed using version 22 of the Statistical Package for Social Sciences. Independent t-tests were employed to compare continuous data, whereas Fisher's exact test compared categorical variables. The results were presented in tables, graphs, and charts. Data Results: Eighty-two patients ages 18–71 years met the inclusion criteria. On the Pittsburgh sleepiness scale, 75.6% reported poor sleep, with a mean of 9.2±4.20. It had no correlation with disease severity on the visual analogue scale or computed tomography scan (p > 0.05), although endoscopy scores revealed a significant correlation (p =0.001). On the Epworth sleepiness scale, 62.2 % exhibited daytime sleepiness ratings of healthy individuals (0-10). It and the Pittsburgh sleepiness scale had a fair agreement (kappa coefficient = 0.24). Conclusions: Poor sleep quality affects a significant percentage of CRS patients, and it is significantly associated with disease severity based only on endoscopic scores. A case-control study is recommended to assess if CRS patients have poorer sleep quality than the general population.
