Trial of a novel plasma gas disinfection system (Radica) to reduce mattress residual bacterial contamination in the acute hospital setting: a preliminary study.

21 Jan 2016

Aim

The purpose of this study is to investigate the ability of a new technology, gaseous technology, to reduce colonization levels, compared to standard cleaning, and so attenuate superficial nosocomial infections.

Methods

We conducted a prospective, single-centre, open-label, non-randomized trial with blinded outcome assessments, comparing the standard cleaning of hospital mattresses with a novel plasma based disinfection system Radica™, followed by a standard post-cleaning culturing protocol (five swabs/mattress).

Results

The median (interquartile range) maximal colony count per mattress for the 20 Radica versus 7 routinely cleaned mattresses was 1 (1–2.7) versus Too-Numerous-to-Count (TNTC) (32-TNTC), respectively, p = 0.002. Of the 20 Radica™ treated mattresses, 12 (60 %) had no positive culture result while all of the standard cleaned mattresses had at least two positive cultures.

Conclusion

The plasma based Radica disinfection system reduces mattress bacterial colonization levels as compared to routine cleaning. This is a potentially important technology in the health care system to reduce surface colonisation and hence nosocomial infections.
