Excel spreadsheet
This workbook provides the decision-support logic accompanying the WHO digital adaptation kit for tuberculosis, translating WHO recommendations into structured decision tables for implementation in digital health systems. It defines standardized business rules, triggers, input expressions, outputs and workflow logic for key tuberculosis care processes, including screening, evaluation of screening results, testing for tuberculosis infection, eligibility for tuberculosis preventive treatment (TPT), preventive treatment regimens and dosages, diagnostic testing, rifampicin susceptibility testing, diagnosis in children, treatment regimen selection, treatment dosing and monitoring. The resource also includes detailed implementation guidance describing decision-table structure, rule syntax, operators and coding conventions. The decision tables are intended to support programme managers, implementers and software developers in embedding evidence-based clinical decision support within digital tuberculosis information systems. The workbook emphasizes that the logic has been derived directly from WHO guidelines and reviewed by clinical experts, while recognizing that limited adaptation may be required to reflect national policies, workflows and local implementation contexts. It highlights the importance of carefully validating any modifications to decision-support logic because these rules directly influence clinical decision-making and the quality of care delivered at the point of service.
