Pulmonary tuberculosis diagnostic delays in Chad: a multicenter, hospital-based survey in Ndjamena and Moundou

摘要: Tuberculosis remains one of the leading causes morbidity and mortality in low-resource countries. One contagious patient can infect 10 to 20 contacts these settings. Delays diagnosing TB therefore contribute spread disease sustain epidemic. The aim this study was assess delays tuberculosis factors associated with public hospitals Moundou Ndjamena, Chad. A structured questionnaire administered 286 new patients evaluate delay (time from onset symptoms first formal or informal care), health-care system health care treatment) total (sum delays). Logistic regression used identify risk long diagnostic (defined as greater than median). median [interquartile range] delay, were 15 [7–30], 36 [19–65] 57.5 [33–95] days, respectively. Low economic status (aOR [adjusted odds ratio] =2.38 [1.08-5.25]), not being referred a service (aOR = 1.75 [1.02- 3.02]) secondary level education (aOR = 0.33 [0.12-0.92]) delay. Risk for low (aOR = 4.71 [1.34-16.51]) belief that traditional medicine cure (aOR = 5.46 [2.37-12.60]). Targeted strengthening system, including improving access, addressing deficiencies health-related human resources, laboratory networks linkages well community mobilization will make better outcomes diagnosis.
