What is the potential contamination rate of non-sterile gloves in clinical use?

Despite intense promotion of hand hygiene as the key measure to protect patients from health care-associated infection, NSCG dominate routine clinical practice and potential cross-contamination occurs in 50% of care episodes” Wilson et al (2017).

Abstract:

Background: Health care workers (HCWs) are recommended to wear nonsterile clinical gloves (NSCG) for direct contact with blood and body fluids. However, there is evidence of extensive inappropriate NSCG use.

Methods: A mixed-methods study comprising observation of NSCG use in 2 acute hospitals and semistructured HCW interviews. Qualitative data were categorized using thematic analysis. Findings were mapped to the Systems Engineering Initiative for Patient Safety model and used to develop a strategy for improving NSCG use.

Results: Two hundred seventy-eight procedures performed in 178 episodes of care involved the use of NSCG. NSCG were inappropriate for 59% of procedures (165 out of 278). Risk of cross-contamination occurred in 49% (87 out of 178) episodes. Twenty-six HCWs were interviewed; emotion and socialization were key factors influencing decisions to use NSCG. Data from observation and thematic analysis were mapped to 6 interacting components of the Systems Engineering Initiative for Patient Safety work system. Interventions targeting each component informed quality improvement strategies

Conclusions: Despite intense promotion of hand hygiene as the key measure to protect patients from health care-associated infection, NSCG dominate routine clinical practice and potential cross-contamination occurs in 50% of care episodes. Such practice is associated with significant environmental and financial costs and adversely affects patient safety. The application of human factors and ergonomics to the complex drivers of inappropriate NSCG behavior may be more effective than conventional approaches of education and policy in achieving the goal of preventing health care-associated infection and improving patient safety.
