This paper addresses the critical issue of healthcare-associated infections (HAIs), particularly methicillin-resistant staphylococcus aureus (MRSA), in healthcare facilities. The paper presents a problem statement documenting the prevalence of nosocomial MRSA infections and identifies contaminated computer keyboards as a potential transmission vector. Using a PICOT framework, the paper proposes a focused intervention targeting critical care nursing staff at tertiary facilities, comparing MRSA infection rates between units where nurses use disposable plastic gloves during computer use and control units. The paper emphasizes the urgent need for awareness among healthcare providers and suggests practical policy modifications to mitigate infection risk.
Despite the implementation of the most rigorous and comprehensive universal precautions, healthcare facilities remain environments where germs and infectious pathogens pose serious risks to patients. Hospitals and clinics are particularly conducive to infectious disease transmission. Nosocomial infections caused by methicillin-resistant staphylococci (MRSA) have become increasingly commonplace across the country. As Boa and Rahube (2013) emphasize, "Numerous nosocomial MRSA outbreaks occur annually due to the widespread prevalence of MRSA within hospitals" (p. 50).
Beyond the array of environmental reservoirs traditionally recognized as infection sources, a significant but understudied potential source of MRSA contamination is the public access computer keyboards used throughout healthcare facilities to input patient data and coordinate care. A study conducted by the University of Toledo examined 24 public access computer keyboards and identified two that were MRSA-contaminated (Boa & Rahube, 2013). Given the proliferation of computer keyboards in healthcare workplaces, more studies of this type are needed to determine the true scope of the problem, though it is reasonable to suggest that keyboard contamination is widespread (Boa & Rahube, 2013).
Given the potential for serious adverse healthcare outcomes associated with MRSA infections, this problem demands increased attention from all healthcare providers who use computers in the workplace—which is to say, all healthcare providers. This is especially true given the high prevalence of MRSA carriage among the healthcare worker population (Saxena & Goyal, 2009). A systematic approach to identifying and mitigating keyboard-related transmission pathways could significantly reduce infection risk in vulnerable patient populations.
Methicillin-resistant staphylococcus aureus (MRSA) represents one of the most clinically significant antibiotic-resistant pathogens in modern healthcare. Unlike methicillin-susceptible strains, MRSA exhibits resistance to multiple beta-lactam antibiotics, limiting treatment options and complicating infection management. The prevalence of MRSA colonization among healthcare workers is particularly concerning because colonized staff members serve as vectors for transmission to vulnerable patient populations.
In healthcare settings, MRSA transmission can occur through direct contact with contaminated surfaces, healthcare worker hands, and shared equipment. Critical care environments present heightened transmission risks because patients in intensive care units (ICUs) often have compromised immune systems, invasive devices, and prolonged hospital stays—all factors that increase susceptibility to nosocomial infection. The routine use of shared computer terminals in these settings creates multiple touchpoints where MRSA can be transmitted from staff to machines and subsequently to other staff members and patients.
To systematically address this clinical problem, the following PICOT (Population, Intervention, Comparison, Outcome, Time) framework provides structure for an evidence-based practice inquiry.
The population of interest is comprised of nursing staff working on critical care wards in a tertiary healthcare facility. Critical care nurses represent a high-risk group for both MRSA colonization and transmission because of their frequent patient contact, use of shared equipment, and high patient acuity. Tertiary facilities manage the most complex cases and serve as regional referral centers, making infection control particularly important.
The variable of interest is exposure to infections due to MRSA contamination via computer keyboards in the healthcare workplace. The specific intervention under investigation is the use of disposable, thin plastic gloves for all computer usage during clinical shifts. This low-cost, minimally disruptive intervention targets the hand-keyboard-hand transmission pathway and aligns with existing precaution protocols.
The study design calls for a comparison between MRSA infection rates in a critical care nursing ward where all nurses use disposable plastic gloves during computer use and a comparable control ward where nurses do not wear disposable plastic gloves. This comparison allows for direct assessment of the intervention's effectiveness while controlling for ward-level factors such as patient acuity, staffing ratios, and baseline infection prevention practices.
The primary outcome is a measurable difference in MRSA infection rates between the intervention and control wards. A reduction in MRSA infection rates in the intervention ward would identify an opportunity to improve patient care by formally integrating keyboard-specific glove protocols into the facility's universal precautions policy. This outcome directly impacts patient safety and hospital quality metrics.
Nursing staff on critical care units represent the ideal population for this intervention because they have high frequency of both patient contact and computer terminal use. Critical care environments—including ICUs, emergency departments, and high-acuity step-down units—have the highest infection rates and the most vulnerable patient populations. By implementing this intervention in these high-risk settings, the potential impact on patient outcomes is maximized.
The intervention itself is deliberately simple and practical. Disposable plastic gloves are inexpensive, readily available, and culturally familiar to healthcare workers who already use gloves for patient care. Requiring glove use during computer access represents a minimal change to workflow while providing a clear barrier between hands and contaminated keyboard surfaces. The gloves can be changed between patients or between computer use sessions, preventing cross-contamination.
The intervention is grounded in basic principles of infection control and standard precautions. Gloves serve as a mechanical barrier that reduces the likelihood of MRSA transfer from contaminated surfaces to intact skin and from colonized hands to keyboard surfaces. This approach is consistent with existing hospital policies and requires minimal staff training or behavioral change.
