Emergency medical services (EMS) workers provide pre-hospital emergency medical care, and have high rates of healthcare associated infections (HCAI). This also presents a challenge to patients who are at risk of cross infections.
Vehicle and equipment readiness is a challenge given the amount of time it takes to thoroughly decontaminate between dispatches, creating greater pressure to increase budgets to expand resources, since cutting corners on patient and staff safety is not an option.
Chemical sprays, foams and diluted liquids for wiping cannot cover all surfaces. They also do not remain in contact for long enough for some pathogens – most disinfectants have a label contact time of 1-10 mins, far longer than a quick spray and wipe. They leave a residue, harm absorbent surfaces, and are hazardous and time-consuming to apply manually.
UVC light is effective but fails to destroy pathogens in the shadows and crevices including air circulation systems.
Conventional cleaning methods have serious effectiveness limitations
