A Review For Infection Control Measures For The Prevention Of Nosocomial Infection

Abstract

Nosocomial infections, also known as hospital-acquired or healthcare-associated infections, pose a significant challenge to patient safety and healthcare systems worldwide. This review examines the current state of knowledge regarding infection control measures for the prevention of nosocomial infections. The hospital environment presents unique factors that contribute to the proliferation and transmission of pathogens, leading to a range of infections. Predisposing factors include underlying patient conditions, medical and surgical interventions, and the hospital's microbial environment. Common nosocomial pathogens include meticillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), Clostridium difficile, and multi-resistant Gram-negative bacteria. These pathogens are associated with various clinical syndromes, such as line-associated infections, bacteraemia, pneumonia, surgical site infections, and urinary tract infections. Effective infection control strategies encompass a multifaceted approach, including hand hygiene, isolation and barrier nursing, aseptic techniques, antibiotic stewardship, surveillance, and engineering considerations in hospital design. The implementation of evidence-based "care bundles" has emerged as a promising approach to collectively reduce infection risks. Despite advancements, nosocomial infections remain a significant concern, requiring ongoing vigilance and a commitment to infection prevention and control measures to ensure patient safety and mitigate the impact on healthcare systems.
