Table 2 Interventions for peripheral diagnosis of tuberculosis (TB) likely to incur large costs in each phase of implementation
Implementation phase | Application | Example |
|---|---|---|
Design phase | Interventions needing large capital outlay for design and adaptation with uncertain scale-up | Implementation of mHealth-facilitated contact investigation for TB requiring procurement and tailoring of software packages |
Initiation phase | Simple interventions with low consumable costs that require changes in policy and workflow | Low-cost lateral-flow LAM assay for TB that necessitates a new supply chain, clinical algorithms, and training of personnel |
Maintenance phase | Interventions that require continued infrastructure support and quality control | Molecular diagnosis of TB with equipment (e.g., Xpert MTB/RIF®) that necessitates service contracts for equipment failure and external quality assurance of test results |
