The Role of Healthcare Professionals in Medical Laboratories, Pharmacy, and Nursing in Improving the Quality of Healthcare

Abstract

The quality of healthcare delivery depends on the coordinated contributions of multiple allied and clinical professions, among which medical laboratory professionals, pharmacists, and nurses occupy particularly central positions across the diagnostic, therapeutic, and caregiving dimensions of patient care. This paper examines the role of healthcare professionals in these three disciplines in improving the quality of healthcare, situating the discussion within Saudi Arabia's Vision 2030 healthcare transformation agenda. Drawing on Donabedian's structure-process-outcome model and the Interprofessional Education Collaborative (IPEC) competency domains, the paper introduces an original conceptual model, TRIAD, which organizes five cross-disciplinary quality levers — Testing Accuracy and Timeliness, Rational Pharmacotherapy and Medication Safety, Individualized Nursing Care and Patient Advocacy, Accountability through Interprofessional Quality Monitoring, and Data-Driven Collaboration and Communication — that connect the distinct contributions of laboratory, pharmacy, and nursing professionals into a shared quality architecture. The paper reviews the discipline-specific functions of diagnostic testing and quality control, clinical pharmacy and medication management, and bedside nursing care and patient safety monitoring, and examines how these functions intersect through interprofessional collaboration. These functions are connected to Saudi regulatory and institutional bodies including the Saudi Commission for Health Specialties (SCFHS), the Central Board for Accreditation of Healthcare Institutions (CBAHI), the Saudi Food and Drug Authority (SFDA), the National Platform for Health Information Exchange Services (Nphies), the Mumaris+ licensing system, and the King Abdullah International Medical Research Center (KAIMRC). Persistent challenges, including workforce shortages, professional silos, and communication gaps, are discussed alongside evidence-based recommendations for healthcare organizations, administrators, and policymakers.
