Burden, spectrum and outcomes of children with tuberculosis diagnosed at a district-level hospital in South Africa.

Abstract

The Khayelitsha subdistrict has the highest burden of reported tuberculosis (TB) cases in Cape Town, Western Cape Province, South Africa. To characterise the TB burden, spectrum and treatment outcomes among children managed at a district-level hospital, the Khayelitsha District Hospital. Retrospective medical record review of all children (age <13 years) diagnosed with TB in January-July 2014. A lay health care worker completed daily surveillance and supported linkage to TB care. Symptoms and investigations at presentation, TB disease spectrum, referral pathways and outcomes were reported. Most children were aged 2 years (84/99, 85%), 18/96 (19%) were infected with the human immunodeficiency virus, 31/91 (34%) were malnourished and 80/99 (81%) had pulmonary TB only. The majority of the children (63/80, 79%) presented with cough of acute onset (<2 weeks). Only 5/36 (14%) eligible child contacts had documentation of receiving isoniazid preventive therapy. Twelve (13%) children had bacteriologically confirmed pulmonary TB. Overall, 93/97 (96%) children successfully continued TB care after hospital discharge. Favourable TB treatment outcomes were recorded in only 77 (78%) children. Children with TB managed at this district-level hospital were young, and frequently had acute symptoms and substantial comorbidities. Missed opportunities for TB prevention were identified. Linkage to care support resulted in excellent continuation of TB care; however, treatment outcomes could be further improved.
