Interprofessional Approaches to the Prevention and Management of Nosocomial Infections: Integrating Pharmacological, Administrative, and Nursing Perspectives

Background: Healthcare-associated infections (HAIs) represent a major global public health challenge, contributing significantly to patient morbidity, mortality, and healthcare costs. These infections, acquired during the course of medical care, are frequently caused by multidrug-resistant organisms and are linked to invasive procedures and devices. Aim: This article aims to synthesize a comprehensive, interprofessional approach to the prevention and management of HAIs, integrating the distinct yet complementary roles of pharmacological, administrative, and nursing perspectives to improve patient safety and outcomes. Methods: The review consolidates evidence on the etiology, epidemiology, and pathophysiology of major HAIs—including central line-associated bloodstream infections (CLABSI), catheter-associated urinary tract infections (CAUTI), surgical site infections (SSI), and pneumonia (HAP/VAP). It evaluates management strategies centered on rapid diagnosis, source control, and targeted antimicrobial therapy, underpinned by robust infection prevention and control (IPC) protocols. Results: Effective management hinges on a triad of rapid source control, timely and pathogen-directed antimicrobial therapy, and unwavering adherence to prevention bundles. Key outcomes include reduced infection rates, shorter hospital stays, lower mortality, and decreased antimicrobial resistance. The success of these measures is fundamentally dependent on seamless interprofessional collaboration. Conclusion: A unified, interprofessional model is paramount for combating HAIs. This model integrates antimicrobial stewardship from pharmacists, rigorous implementation of IPC protocols by nursing staff, and supportive policy and resource allocation from administrators to create a safer healthcare environment.
