The Relationship Between Sleep Quality and Fatigue Levels in Patients with Pulmonary Tuberculosis Undergoing Treatment

Background: Patients with pulmonary tuberculosis (TB) undergoing treatment may experience poor sleep quality and fatigue, potentially affecting daily activities and quality of life. Objective: This study aimed to examine the relationship between sleep quality and fatigue levels among patients with pulmonary TB undergoing treatment. Methods: This observational analytic study employed a cross-sectional design. The study was conducted in April 2026 at Primary Health Center X, Deli Serdang Regency, Indonesia, involving 21 participants selected through total sampling. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), while fatigue was measured using the Fatigue Severity Scale (FSS). Spearman's correlation test was planned with a significance level of α = 0.05. Results: According to the data presented in the manuscript, 14 participants (66.7%) had poor sleep quality, while 7 participants (33.3%) had good sleep quality. Moderate fatigue was the most frequent category, reported in 8 participants (38.1%), followed by severe fatigue in 7 participants (33.3%) and mild fatigue in 6 participants (28.6%). Cross-tabulation indicated that all participants classified as having severe fatigue belonged to the poor sleep quality group. Conclusion: The descriptive findings suggest a tendency toward greater fatigue among patients with poor sleep quality. However, the statistical significance of this relationship remains unconfirmed pending verification of the analysis using individual participant data
