Case Study: Aerosol Disinfection in the Medical Sector

Hospital, Philippines, Victoria I. Ching, RN, MGM-ESP Manager: „When I assumed leadership of infection control at MCO, we were grappling with an increasing number of nosocomial infections and multi-resistant organisms. A few months after introducing Sanosil aerosol disinfection, in conjunction with other measures, we were able to reduce the infection rate by 70%, from >10/1000 PT-days to <3/1000 PT-days, and maintain it at a stable level.“

Automated Room Disinfection through Airborne System in Medical and Care Settings

With the significant increase in antibiotic-resistant germs in care facilities, aerosol disinfection is becoming increasingly crucial. It provides an additional layer of safety to reduce the risk of nosocomial infections and save lives. Additionally, it serves as a valuable tool for containing outbreaks of infectious germs such as noroviruses.

Aerosol disinfection effectively complements traditional surface disinfection in medical and care settings, helping to close hygiene gaps. In aerosol disinfection, disinfectants are sprayed into the air in the form of fine particles, thoroughly disinfecting previously unreachable areas such as room air and hard-to-access surfaces. This method enables comprehensive decontamination, even on surfaces that may be overlooked by traditional manual spray-wipe disinfection methods.

Whole-Room Disinfection in the Medical Field: Frequently Asked Questions (FAQ)

Q: Can aerosol disinfection replace traditional cleaning or manual spray-wipe disinfection?

A: No, it cannot. While aerosol disinfection provides more comprehensive and better coverage of all surfaces compared to wipe disinfection, it has limited penetration depth. Even small dirt residues can significantly reduce the effectiveness of aHP disinfection, making thorough pre-cleaning indispensable. The aerosol technology is an additional safety measure for mitigating microbiological risks.

Q: Can aerosol disinfection be quickly performed between two patients or surgeries?

A: No. Due to the time required for thorough 3D room disinfection, this technology is less suitable for quick interim disinfection. However, it is well-suited for thorough base disinfection in conjunction with other hygiene measures.

Q: How long does aerosol disinfection with the Q-Jet devices take?

A: The required time consists of A) the spraying time – the time it takes to nebulize a certain amount of disinfectant in a room, and B) the necessary exposure and decomposition time. During the exposure time, germs are actively reduced. Simultaneously, the hydrogen peroxide breaks down into water and oxygen. This process takes at least 120 minutes.

Q: Can aerosol disinfection be performed in the presence of people (or animals)?

A: No, that is not possible. (Unless they are protected by an ABEK-P3 full-face protective mask.)

Q: Are electronic devices damaged by aerosol disinfection with boosted hydrogen peroxide?

A: Various independent studies and our own experiences show that electronic devices such as PCs, tablets, flat screens, mobile phones, etc., are not affected by aerosol disinfection with hydrogen peroxide. In contrast, chlorine dioxide or peracetic acid solutions can compromise the integrity of electronic devices.

Q: What are the advantages of Sanosil disinfectants with boosted hydrogen peroxide compared to other products used for this purpose?

A: Sanosil Q-Dis (and S015) are exceptionally suited for whole-room disinfection. They

  • pose fewer health risks and problems compared to vaporized formaldehyde,
  • are gentler on materials and less odorous than peracetic acid-hydrogen peroxide systems,
  • are easier to establish in cycles and safer to handle than H2O2 vapor systems (VpHP),
  • do not promote microbial resistance like QAV products,
  • have comprehensive tested efficacy (Standard EN 17272 / AFNOR NFT 72-281) – unlike most systems with anolyte, active chlorine, or hypochlorous acid.

Q: What nebulization technologies and devices are distinguished for room disinfection via aerosol?

A: Nebulization devices fundamentally use two technologies to generate aerosols: compressor & nozzle or turbine. A compressor forces the disinfectant through a nozzle, creating aerosols. In contrast, a turbine uses an airstream to entrain the disinfectant via the Venturi effect and finely atomize it. Both technologies have their preferred application areas. Compressor devices are more suitable for small to medium-sized rooms, while turbine devices are better suited for medium to large rooms.
(The Sanosil Q-Jet CT-20 features both technologies and can thus be used for rooms with a volume of 4 to 600 m³.)

Q: What is the difference between a spray mist device and an aerosol device for automated room disinfection?

A: Portable spray devices are not classified as traditional aerosol devices. Their primary purpose is to manually and directly spray surfaces with a fine mist. This inevitably produces aerosols, necessitating the use of appropriate personal protective equipment during disinfection. Unlike aerosol disinfection devices, however, the majority of the sprayed disinfectant lands directly on the treated surfaces due to the directed spray direction. These surfaces typically remain moist.

Aerosol devices, on the other hand, generate a „dry“ mist that evenly distributes throughout the room. This avoids wetting surfaces with the disinfectant.
