• Description:
  Objective: Retractable intravascular catheters (RIVCs) with ESIP have not been investigated for blood splatter potential. Research questions were: do RIVCs produce blood splatter, and does splatter frequency differ between visual methods vs. microscopy? Methods: 100 RIVCs of the same brand were placed in a testing chamber with scientific filters labeled A, B & C, to capture blood spatter after activation in a simulated brachial venous system. Differences in filter mass, visual and microscopic analysis for blood were the units of analysis. Descriptive statistics, paired t-tests and kappa statistics were used for data analysis. Results: The proportions of filters B and C with blood detected by the naked eye were 12% and 13% respectively. But for filter A, visual vs. microscopic methods detected blood 70% and 71% respectively. A statistically significant difference was observed in mean mass of filter A between pre- and post-activation confirmed visually (t= - 0.0013, p= 0.01400) and microscopically (t= - 0.00014, p= 0.0092). Kappa statistics indicated substantial agreement between methods for filters A, B and C. However, in 6 instances (6%), blood was detected by microscopy and not by the naked eye. Conclusion: A potential for bloodborne pathogen exposure with use of a specific RIVC was detected. Scientific filters captured blood splatter that was not noticeable by the naked eye but was detected by microscopy in 6% of the instances. Therefore, healthcare workers (HCW) may not be able to detect blood splatter when it occurs and may not report a splash to mucous membranes or non-intact skin. This study reinforces the need for HCWs to wear personal protective equipment (e.g., masks, face shields, goggles) when using RIVCs. [Description provided by NIOSH]
