This study aims to provide valuable insights into the challenges faced by TB patients, which can inform better strategies for treatment and management in the future.Patients and Methods: We conducted a study in King Fahad Medical City, Riyadh, Kingdom of Saudi Arabia (KSA), from January 1, 2018 to December 31, 2023. The study was a registry-based retrospective cohort study. Patients’ data were sourced from the National Tuberculosis Registry database of Saudi Arabia. Treatment outcomes were determined as either success or failure, considering clinical evaluation, changes in chest X-rays, and the results of subsequent sputum examinations during follow-up. To evaluate the data, SPSS version 28.0 was used.Results: A total of 427 PTB patients participated in the study. The results show successful treatment outcomes among 88.5% of patients. Among the patients, males exhibited a higher likelihood of treatment failure as compared to females (aOR 1.3; 95%Cl 1.2– 1.5, p < 0.001). Patients with positive sputum smear (aOR 1.3; 95%Cl 1.1– 1.3 p < 0.00) and the presence of cough were associated with an increased risk of treatment failure (aOR1.5; 95%Cl 1.1– 1.4, p < 0.001).Conclusion: This study shows that the percentage of unsuccessful treatment outcomes is high, ie, 11.5%, due to patients’ deaths and loss to follow-up. Enhanced supervision and treatment monitoring for tuberculosis patients at high risk of treatment failure can lead to improved treatment success rates in Saudi Arabia.Keywords: tuberculosis, treatment outcomes, retrospective study, Saudi Arabia
