"It's about time they taught us": a qualitative study evaluating the barriers to finding and screening child contacts under five at risk for TB in Gauteng Province, South Africa from the provider and caregiver perspectives.

BACKGROUND: Inadequate numbers of children under five years of age who are exposed to tuberculosis (TB) in the home (child contact) are initiated on TB preventive treatment (TPT) in South Africa. We assessed barriers of initiating isoniazid preventive therapy (IPT) in this age group.

METHODS: We conducted a qualitative study at two primary health clinics in the Ekurhuleni district in Gauteng Province. Between April and July 2019, we enrolled facility managers, TB staff and parents or legal guardians of child contacts (caregivers) attending for care, at the two facilities. Semi-structured questionnaires, facility observations and in-depth interviews using a semi-structured interview guide were used to collect data. Findings from the semi-structured questionnaires with facility staff and facility observations were summarized. Thematic analysis with a deductive approach was used to analyse the data from the in-depth interviews with caregivers.

RESULTS: Two facility managers took part in the study and were assisted to complete the semi-structured questionnaires by TB staff. Fifteen caregivers aged between 18 and 43 years were interviewed of which 13 (87%) were female. Facility managers and TB staff (facility staff) felt that even though caregivers knew of family members who were on TB treatment, they delayed bringing their children for TB screening and TPT. Facility staff perceived caregivers as not understanding the purpose and benefits of TB prevention strategies such as TPT. Caregivers expressed the desire for their children to be screened for TB. However, caregivers lacked knowledge on TB transmission and the value of TB prevention in children at high risk of infection.

CONCLUSION: While facility staff perceived caregivers to lack responsibility, caregivers expressed limited knowledge on the value of screening their children for TB as reasons for not accessing TB preventive services. Health education on TB transmission, screening, and TB prevention strategies at a community level, clinics, creches, schools and via media are important to achieve the global end TB goal of early detection and prevention of TB.
