Abstract

SETTING: Diagnosing pediatric tuberculosis (TB) is difficult; to improve diagnosis gastric aspiration (GA) was performed in 121 Botswana health facilities.

OBJECTIVE: To describe treatment initiation and outcomes in children with a positive GA result and those treated empirically.

METHODS: Children with smear or culture-positive GA or those clinically diagnosed were referred for anti-tuberculosis treatment. Treatment initiation and outcomes were assessed from February 2008 to December 2012 using name-based matching algorithms of the GA database; treatment initiation was captured in the electronic TB registry. Analyses included descriptive statistics and regression models.

RESULTS: GA was conducted in 1268 children. Among these, 121 (9.5%) were GA-positive; and treatment was initiated in 90 (74.3%). An additional 137 (11.9%) were treated empirically. More than a third (36.4%) had known human immunodeficiency virus status (positive or negative); this was significantly associated with TB treatment initiation (adjusted odds ratio [aOR] 1.8, 95%CI 1.3-2.5); < 0.05). Among the 90 children with a positive GA result, nearly all either completed treatment (78.9%) or were on treatment (20.0%) at the time of data collection.

CONCLUSION: We could not find documentation of treatment for more than a quarter of the children with laboratory-confirmed TB, an important gap that calls for further examination. The failure to initiate prompt treatment requires investigation and urgent action.
