Effectiveness and cost-effectiveness of community-based directly observed treatment (DOT) versus health facility-based DOT of tuberculosis in Africa: protocol for a systematic review and meta-analysis

Background Tuberculosis (TB) remains a significant global health challenge, especially prevalent in the WHO African region. The WHO’s End TB Strategy emphasises effective treatment approaches such as directly observed therapy (DOT), yet the optimal implementation of DOT, whether through health facility-based (HF DOT) or community-based (CB DOT) approaches, remains uncertain. Objective To conduct a systematic comparison of the effectiveness and cost-effectiveness of Community-Based Directly Observed Treatment (CB DOT) versus Health Facility-Based Directly Observed Treatment (HF DOT) for tuberculosis (TB) treatment in African settings. Methods We will conduct a systematic review and meta-analysis following Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. We will search PubMed, Embase, Web of Science, Scopus and the Cochrane Library for articles published up to 30 March 2023, without date restrictions. Eligible studies must be full economic evaluations conducted in African countries, comparing CB DOT to HF DOT regarding treatment outcomes and costs. Exclusion criteria include non-English, non-peer-reviewed or studies lacking caregiver involvement in CB DOT, health facility-based DOT comparison, direct comparability between CB DOT and HF DOT, significant selection bias or non-economic evaluations. Data extraction will be performed independently by reviewers, and meta-analyses will use STATA software. To pool the data, a random-effect...
