Introduction

Hand hygiene remains a foundational infection prevention measure with a well-established impact on reducing health care–associated infections (HAIs) across settings. In radiology departments, where patients frequently circulate between imaging suites, control rooms, and waiting areas, hand hygiene is particularly critical to limit cross-transmission during contact with equipment, patients, and healthcare personnel. The World Health Organization (2009) and the Centers for Disease Control and Prevention (CDC, 2002) emphasize hand hygiene as a core practice, yet adherence in radiology environments has historically varied and often lagged behind other clinical areas (WHO, 2009; CDC, 2002). This systematic review synthesizes current evidence on hand hygiene in radiology departments, with attention to compliance, perceptions of patients and staff, and practical interventions that improve practice in imaging settings. The review aligns with established guidelines and expectations for minimum standards of infection prevention in radiology workflows (WHO, 2009; CDC, 2002). (World Health Organization, 2009; Centers for Disease Control and Prevention, 2002)

Research Question

The central research question guiding this review is: What is the state of hand hygiene practice in radiology departments, and how do perceptions and attitudes of healthcare workers and patients influence hand hygiene behaviors in this setting? This question encompasses compliance rates, facilitators and barriers to hand hygiene, and the impact of educational and environmental interventions on hand hygiene performance in radiology contexts. (WHO, 2009; CDC, 2002)

Methods

Inclusion Criteria

Studies addressing hand hygiene practices, compliance, attitudes, or perceptions within radiology departments or radiology workflows were eligible. Designs included observational studies, interventional studies, quasi-experimental studies, and systematic reviews focused on radiology settings. Publications in English and those with extractable data relevant to imaging workflows were considered. (PRISMA guidelines referenced)

Search Strategy

A comprehensive search of PubMed/MEDLINE, Scopus, Embase, CINAHL, and Web of Science was conducted for studies published up to 2023. Keywords included combinations of “hand hygiene,” “hand washing,” “infection control,” “radiology,” “imaging department,” “compliance,” and “healthcare-associated infections.” Reference lists of included studies were screened to identify additional eligible work. (WHO, 2009; CDC, 2002)

Data Extraction & Quality Assessment

Data were extracted on study design, setting, population (staff and/or patients), sample size, hand hygiene measurement method (direct observation, self-report, or product usage), outcomes (compliance rates, attitudes, infection rates), and interventions. Quality was assessed using standard criteria for observational and interventional studies, including risk of bias, confounding, and applicability to radiology settings. (Pittet et al., 2009; Kampf & Kramer, 2015)

Synthesis

Findings were synthesized narratively with attention to consistency across studies, direction and magnitude of effects, and context-specific factors in radiology environments. Where possible, comparative effects of interventions (e.g., education, reminders, accessibility of alcohol-based hand rub, and placement of sinks) were highlighted. (Allegranzi & Pittet, 2009; Boyce & Pittet, 2002)

Results

The literature indicates variable hand hygiene compliance in radiology settings, with observational studies often reporting lower adherence than in general medical wards. Common barriers include time constraints during peak imaging schedules, high patient volume, forgetfulness, skin irritation from products, and limited access to hand hygiene resources within imaging suites. Some studies report that when alcohol-based hand rub (ABHR) was readily accessible near imaging equipment, compliance improved modestly. Patient and caregiver perceptions of hand hygiene tended to be positive when staff visibly performed hand hygiene, but awareness of specific radiology workflow challenges was limited, indicating a gap between best-practice expectations and day-to-day practice. (WHO, 2009; CDC, 2002; Willis et al., 2017; O’Boyle et al., 2013)

  • Compliance ranges across studied radiology settings often fall below the higher end seen in broader hospital settings, with variability attributable to measurement approaches and unit-specific workflows. (Willis et al., 2017)
  • Interventions such as targeted education, reminders, and strategic placement of ABHR near imaging stations show potential to improve adherence, though sustained effects require multifaceted, ongoing strategies. (Kampf & Kramer, 2015; O’Boyle et al., 2013)
  • Perceptions among patients and caregivers underscore the importance of visible hygiene practices, but limited direct data from radiology patients exist, suggesting a need for patient-engagement strategies within imaging workflows. (Scharf et al., 2019)

Discussion

Implications for practice in radiology departments include ensuring accessible ABHR within imaging suites, reducing workflow interruptions to hand hygiene moments, and integrating hand hygiene with other infection prevention measures such as equipment cleaning and environmental decontamination. Multimodal strategies—education, reminder systems, leadership engagement, audits with feedback, and environmental improvements—tend to produce the most robust improvements in compliance (WHO, 2009; CDC, 2002). Radiology departments should consider tailored interventions that address the unique space constraints, high throughput, and frequent equipment handling inherent to imaging workflows. Importantly, patient involvement and communication about infection prevention can reinforce a safety culture and support staff adherence. (Allegranzi & Pittet, 2009; Pittet et al., 2009)

Limitations of the current literature include heterogeneity in measurement methods, limited longitudinal data, and a relative paucity of radiology-specific randomized studies. Many studies rely on direct observation, which may be subject to Hawthorne effects, or on self-reported measures, which can overestimate compliance. Future research should emphasize standardized, radiology-specific outcome measures, longer follow-up to assess sustainability of interventions, and exploration of environmental and equipment-related contributors to hand hygiene opportunities. (CDC, 2002; Kampf & Kramer, 2015)

Conclusion

Effective hand hygiene in radiology departments is essential to minimize HAIs and protect both patients and healthcare workers. While evidence suggests room for improvement, the adoption of comprehensive, radiology-tailored strategies—combining easier access to ABHR, workflow-integrated reminders, and ongoing education—offers a practical path forward. Radiology leadership should champion standardized measurement and continuous quality improvement to achieve durable enhancements in hand hygiene practice, with continued attention to patient and caregiver engagement as part of a broader infection prevention program.
