Supplier Evaluation Practices on Sustainable Performance of Selected County Referral Hospitals in Kenya

Purpose: The sustainability of healthcare service delivery in public hospitals is highly dependent on effective procurement and supplier management practices. This study examined the influence of supplier evaluation practices on the sustainable performance of selected County Referral Hospitals in Kenya. Specifically, it focused on four key dimensions of supplier evaluation: supplier appraisal practices, supplier capacity management, supplier relationship management, and supplier commitment. Methodology: The study adopted a descriptive research design. Primary data was collected using structured questionnaires from procurement staff and departmental heads in selected County Referral Hospitals. A total of 86 respondents participated in the study, yielding a high response rate of 90 percent. Descriptive and inferential statistical analyses were conducted using SPSS version 26. Findings: The results revealed that all four supplier evaluation dimensions positively and significantly influenced the sustainable performance of County Referral Hospitals. Supplier commitment had the strongest effect, followed by supplier relationship management, supplier appraisal, and supplier capacity management. The findings suggest that structured supplier evaluation enhances procurement efficiency, improves service delivery, and contributes to long-term sustainability in the public health sector. The study concludes that supplier evaluation is a strategic enabler of sustainable hospital performance and not merely an administrative requirement. Unique Contribution to Theory, Policy and Practice: It recommends that hospitals strengthen supplier appraisal frameworks, institutionalize capacity assessments, cultivate long-term supplier relationships, and prioritize supplier commitment in procurement decisions. Further studies are recommended to explore the role of supplier innovation and ethical sourcing in public healthcare performance. The findings of this study are expected to inform policy formulation, enhance procurement practices, and support sustainable healthcare delivery in Kenya.
