Sleep Quality on Maintenance Hemodialysis Patients in Douala General Hospital in Cameroon

Abstract

Background: Poor sleep quality is reported to be common in hemodialysis patients. However, limited data are available about its prevalence in sub-Saha- ran region. The aim of this study was to assessed sleep quality and its predictors among hemodialysis patients. Methods: We conducted a cross sectional study of 2 weeks in the Douala General Hospital hemodialysis center of Cameroon involving 46 chronic hemodialyzed patients for at least six months with arteriovenous fistula. Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) and laboratory data were collected in patients’’ fields. Result: Thirty-five (76.1%) subjects reported poor sleep quality. The most frequent abnormal sleep components were subjective sleep quality, sleep disturbances and sleep latency (87%, 85% and 76% respectively). In univariate linear regression, hemoglobin level, sleep quality, sleep latency, sleep duration, habitual sleep efficiency and sleep disturbance were associated with poor sleep quality. In multivariate linear regression only hemoglobin level (p = 0.004) and sleep latency (p = 0.002) were associated with poor sleep quality. Conclusion: Poor sleep quality is frequent in our hemodialysis patients and hemoglobin seems to be a good predictor of sleep quality in these patients.
