Table 3. Examples of possible options analyses and recommendations to address gaps that are identified in the management of child contacts of adult TB cases.
Problem | Options | Evidence Analysis | Feasibility Analysis | Recommendation |
Low screening attendance due to knowledge gap, distance, and cost issues | 1. Educational video | Well received in relation to TB disease [26] | Subject to equipment and expertise availability | Develop and evaluate educational video for TB patients and contacts |
2. Decentralised symptom-based screening in the community and at community health centres | Decentralised provision of TB treatment improves uptake and completion [27]; symptom-based screening is safe [28] | Low cost; increased community clinic work load. | Symptom-based screening in the community; clinical evaluation and management at community clinics | |
3. Cash transfer to stimulate attendance and subsequent adherence | Conditional cash transfer systems increase attendance at preventive treatment programmes [29]. Cost effectiveness is unclear. | Significant cost implications up front that need to be addressed | Pilot a cash transfer intervention with before and after evaluation, subject to finances | |
Over-diagnosis of TB disease in children | 1. Specialised training in diagnosis of TB disease in children | Limited published evidence of effect on diagnostic accuracy | 2 day centralised training courses are the most cost-effective | Introduce 2- to 5-day in-country training in diagnosis of child TB disease annually |
2. Remote interpretation of digital chest X-rays by WHO-accredited radiologists | Quality of X-rays and reading is acceptable and reliable | High cost of installation of digital X-ray machines | Consider digital X-ray and remote reading if high levels of over-diagnosis persist after training | |
Low adherence | 1.Changing therapy from 6 months INH to 3 months RIF and INH | Efficacy is equivalent in adults but unclear if side effect profile is worse for 3-month regimen [30]. Some evidence of equivalent efficacy and improved adherence in children [8]. | Lower cost; one extra medicine | Cohort study required for side effect profile in children before a change to 3-month regimen |
2. Parallel DOTs for children on preventive treatment with DOTs for index case | Some evidence that DOTs for preventive treatment would be effective [8] | Increased cost to provide DOTs, although economies of scale optimised if in parallel to index case DOTs | Introduce a modified DOTs programme for preventive treatment in parallel and overlapping with index case DOTs. Before and after evaluation. |
DOT, directly observed therapy; INH, Isoniazid; RIF, rifampicin.
