The widespread practice among nurses of wearing nonsterile gloves while preparing and administering intravenous (IV) antibiotics lacks solid evidence-based support. Despite being deeply embedded in clinical routines, this habit is more ritualistic than scientifically justified. A recent scoping review published in the Journal of Advanced Nursing reveals significant gaps in research and guidelines addressing the proper use of gloves during IV antibiotic procedures.
Origins and Consequences of Glove Use Habits
Nonsterile gloves have become standard in nursing practice largely due to universal precautions initiated during the HIV epidemic. These gloves help reduce pathogen transfer and protect healthcare workers from exposure to infectious materials and irritant chemicals. However, their indiscriminate use, especially in processes like IV antibiotic preparation, may undermine essential infection control measures such as hand hygiene.
The World Health Organization (WHO) estimates that healthcare-associated infections affect 7% to 15% of hospitalized patients globally, and these infections are often driven by lapses in hand hygiene and improper glove use. Emotional reactions like disgust and anxiety significantly influence glove usage, frequently overriding scientific protocols and leading to misuse.
Impact on Infection Control and Healthcare Costs
Hand hygiene remains the cornerstone of infection prevention, reducing transmission risks and antimicrobial resistance. Yet, observed behavior among healthcare workers often falls short of recommended hygiene standards, potentially due to misplaced trust in glove protection. This inattentiveness promotes cross-contamination between healthcare workers, patients, and environments, escalating infection rates, treatment complications, and healthcare expenses.
Moreover, improper glove use amplifies environmental concerns. Vinyl and nitrile gloves are non-biodegradable and contribute to significant medical waste. Their production and disposal produce carbon emissions and release harmful chemicals, heavy metals, and microplastics into ecosystems. Effective infection prevention programs incorporating proper hand hygiene and glove use could reduce associated healthcare costs significantly, with a return of about $16.50 saved for every dollar invested.
Current Evidence and Research Gaps on Glove Use in IV Antibiotics
The study authors conducted a comprehensive search of five major databases and gray literature sources up to February 2024 but identified only three studies directly relevant to nonsterile glove use during IV antimicrobial preparation and administration. Among 24 initially selected sources, only one met strict inclusion criteria. The rest either lacked focus on glove use or were insufficiently evidence-based.
Findings indicate that nonsterile gloves are frequently used in various nursing tasks, including cleaning, patient mobilization, and hygiene—with up to 59% of glove use deemed unnecessary. This practice often stems from habit, misunderstandings about glove hygiene superiority over handwashing, and emotional factors like fear of contamination.
Importantly, WHO’s “Five Moments of Hand Hygiene” outline critical points for hand cleaning to minimize contamination risks, yet nurses were found less likely to clean hands after glove removal compared to other healthcare professionals. Two studies recommend glove use only when exposure to body fluids or mucous membranes is likely, explicitly advising against gloves for preparing and administering IV antibiotics. However, these recommendations lack direct empirical backing.
A Call for Evidence-Based Practice and Updated Guidelines
The review highlights a troubling scarcity of original research supporting current glove use practices in the context of IV antibiotic handling. The few existing studies are limited in scope, dated, and often inter-referencing the same small pool of authors, underscoring the urgent need for rigorous research and clear, evidence-based guidelines.
Given the potential impacts on patient safety, healthcare costs, and environmental sustainability, healthcare institutions and policymakers should critically reassess routine nonsterile glove protocols in IV antibiotic administration. Fostering adherence to hand hygiene standards and optimizing glove use based on solid evidence can enhance infection control and reduce unnecessary waste.
