Background: Delayed diagnosis of tuberculosis (TB) can enhance the transmission of infection and worsen prognosis.Aim: To identify the risk factors of delay in the management of TB cases for early management.Patients and methods: A cross-sectional analytic study was performed to assess the proportion, duration of delay, and its determinants in the diagnosis and management of TB. To assess the risk factors of delay, the sample was dichotomized into ‘delay’ and ‘nondelay’ groups taking the median total delay in the diagnosis and management of TB as a cutoff point. The study included 183 TB patients, who were registered in TB records during the study period (first of January to end of June, 2017). Data were collected by an interview questionnaire.Results: Nearly half of patients (49.20%) had unacceptable total delay in the diagnosis and management of TB. The median of total delay, patient delay, and health-care system delay were 65, 14, and 20 days, respectively. Significant risk factors of total delay in the diagnosis and management of TB were not consulting the health-care provider after onset of symptoms (P=0.002), visiting initially the health facility other than the chest hospital/TB clinics (P=0.019), not consulting a chest physician initially (P=0.043), negative sputum smear (P=0.001), more than two health visits before initial diagnosis (P<0.001), while low-degree TB stigma was protective (P=0.006).Conclusion: Nearly half of patients had unacceptable total delay in the diagnosis and management of TB. The main determinants were seeking pharmacies instead of visiting health-care providers, not visiting initially chest hospital/TB clinics, not consulting a chest physician initially, negative sputum smear, and more than two health visits before initial diagnosis.
