Discusión: Systemic Barriers and Service Integration
The synthesis of operational evidence indicates that centralized procurement frameworks, while theoretically capable of generating economies of scale, often encounter friction at the point of primary-care distribution. Logistical fragmentation across secondary and first-level healthcare facilities creates localized stock-outs that disproportionately affect chronic disease management and acute primary consultations [1]. Although consolidated purchasing intends to harmonize inventory flows, administrative delays in resource disbursement and inadequate demand forecasting persistently undermine clinical readiness across regional centers [2]. Furthermore, the capacity of primary health units to absorb redirected patient loads depends heavily on clinical workforce stability and functional support systems, which remain constrained during structural transitions [5], [8]. Consequently, the realization of comprehensive access within the IMSS-Bienestar model is contingent upon closing the gap between macro-level logistical planning and micro-level clinic replenishment. Without synchronized multi-echelon inventory tracking and dedicated primary-care resource allocation, administrative consolidation risks reproducing historical patterns of therapeutic vulnerability in decentralized facilities [1], [2].
