Elucidation of potential challenges and prospects for regional tuberculosis interventions in East and Horn of Africa: a cross-sectional program assessment

INTRODUCTION: cross-border mobility of persons with Tuberculosis (TB) is a global public health concern. We aimed at documenting health systems´ potential bottlenecks and opportunities in pulmonary TB continuum of care in cross-border expanses of East and Horn of Africa. METHODS: a cross-sectional program assessment with descriptive analysis of TB services, health staff capacities, diagnostic capacities, data management and reporting, and treatment outcomes. Data were extracted from health facility TB registers and semi-structured key informant interviews conducted in selected 26 cross-border sites within the 7 member states of the Intergovernmental Authority on Development (IGAD) region. RESULTS: the overall cross-border TB cure rate in the year preceding the study (37%) was way beneath the global target with considerable variations amongst the study countries. The restricted support to the cross-border health facilities was mediated and even exacerbated by expansive distances from the respective capital cities. Restricted geographical access to the facilities by cross-border populations was a longstanding challenge. Substantial staffing gaps, TB service delivery capacity needs and inadequate diagnostics were noticeable. The TB control guidelines were not harmonized between the countries and the inter-country referral systems were either absent or inappreciable, contributing to ineffective cross-border referrals and transfers. The frail linkages between stakeholders were contemptible, but increasing governments´ commitments in tackling infectious diseases were encouraging. CONCLUSION: cross-border TB interventions should drive regional TB policies, strategies and programs that sustain countries´ coordination, harmonization of management guidelines, advocacy for increased human resources support, enhanced capacity building of cross-border TB staff, adequate diagnostics equipping of the cross-border health facilities and seamless transfer and referral of patients traversing boundaries.
