Breaking the Chain: Eliminating Bloodborne Pathogen Transmission Through Safe Injection Practices in Healthcare Settings

Abstract

Unsafe injection practices remain a preventable cause of healthcare-associated infections worldwide, despite comprehensive guidelines from the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO). Bloodborne pathogens such as hepatitis B virus (HBV), Hepatitis C Virus (HCV), and Human Immunodeficiency Virus (HIV) can be transmitted through syringe/needle reuse, improper multidose vial handling, and inadequate aseptic technique. Historical WHO estimates (circa 2000–2010) attributed approximately 1.67 million HBV infections, 315,000 HCV infections, and 34,000 HIV infections annually to unsafe injections. Although global interventions including safety-engineered devices and HBV vaccination programs have substantially reduced this burden, unsafe practices persist in resource-limited settings. The WHO Global Hepatitis Report 2024 indicates that viral hepatitis caused 1.3 million deaths in 2022, with unsafe medical injections remaining a preventable transmission route.
This article reviews evidence-based injection safety standards, highlights common unsafe practices (including "double-dipping," vial reuse, and syringe reuse), and outlines organizational strategies to foster a safety culture. By consistently applying the principle "One Needle, One Syringe, Only One Time," healthcare providers can eliminate preventable transmission of bloodborne pathogens and protect patients and staff.
