Prevalence And Risk Factors Of Hospital-Acquired Infections In Tertiary Care Hospitals In Saudi Arabia

Abstract

Hospital-acquired infections (HAIs) remain a persistent challenge for healthcare systems worldwide, particularly in tertiary care hospitals where patient acuity, invasive procedures, and prolonged hospital stays converge. In Saudi Arabia, rapid healthcare expansion, increasing reliance on advanced medical technologies, and the growing burden of chronic disease have intensified concerns regarding HAIs. This paper examines the prevalence and major risk factors associated with hospital-acquired infections in tertiary care hospitals across Saudi Arabia. Drawing on published epidemiological studies, surveillance reports, and institutional data, the analysis highlights the most common infection types, including bloodstream infections, ventilator-associated pneumonia, surgical site infections, and catheter-associated urinary tract infections. Particular attention is given to patient-related factors, healthcare practices, environmental conditions, and antimicrobial resistance patterns that shape infection dynamics in Saudi tertiary settings. The findings suggest that while national infection control initiatives have improved surveillance and reporting, HAIs continue to pose significant clinical and economic burdens. The paper argues that sustained reduction in HAI prevalence requires not only adherence to infection prevention protocols but also systemic interventions addressing staffing, antimicrobial stewardship, hospital infrastructure, and continuous professional training.
