Strategic Supply Chain Management in Pathological Laboratories: Cost Optimization and Quality Outcomes in Diagnostic Services

Abstract

Pathological laboratories are central to modern healthcare, influencing approximately 70% of all clinical decisions, yet they continue to face persistent challenges in operational efficiency, cost containment, and diagnostic quality. The convergence of strategic supply chain management (SCM) principles with laboratory operations has emerged as a critical intervention domain capable of addressing these challenges simultaneously. This study investigates the application of strategic SCM frameworks in pathological laboratories with a dual focus on cost optimization and quality outcomes in diagnostic services. A convergent parallel mixed-methods design was employed, incorporating 24-month longitudinal cost and performance data from 45 tertiary-care pathological laboratories across South Asia, Sub-Saharan Africa, and Southeast Europe, supplemented by semi-structured interviews with 30 laboratory managers, supply chain officers, and nursing managers. Baseline SCM maturity assessments revealed that over half of the study laboratories operated reactively, with fragmented procurement, manual inventory systems, and no formal vendor contracts. Following the implementation of targeted SCM interventions — including vendor consolidation, just-in-time inventory protocols, digital procurement platforms, and staff training — laboratories achieved a mean reduction of 23.4% in reagent procurement costs, 18.7% in reagent wastage expenditure, and 41.6% in emergency procurement incidents. Diagnostic turnaround time improved by 31.2% on average, critical value reporting compliance rose from 78.3% to 91.7%, and equipment downtime incidents declined by 33.9%. Nursing managers in high-SCM-maturity settings reported measurable improvements in workflow efficiency and reduced supply-related disruptions to patient care. The findings demonstrate that strategic SCM adoption in pathological laboratories yields significant and sustained improvements across financial, clinical, and operational dimensions. Healthcare administrators, laboratory leaders, and nursing management professionals are strongly encouraged to integrate supply chain governance competencies into laboratory management frameworks to build cost-effective, high-quality and resilient diagnostic services.
