  2. What we will learn • The evolution of UVC light • UVC in Healthcare • New technologies to be used with UVC light a. ATP meter b. Glow germ

  3. UVC Light Ultraviolet-denoting electromagnetic radiation of wavelength shorter than that of the violet end of the spectrum, having wavelengths of 4-400 nanometers. • Ultraviolet A-Ultraviolet Radiation with wavelengths between 320 and 400 nm. • Ultraviolet B-Ultraviolet Radiation with wavelengths between 290 and 320 nm. • Ultraviolet C-Ultraviolet Radiation with wavelengths between 200 and 290 nm. UVC Light has been used to sanitize water for over 100 years, UV Light is found in sunlight and emitted by electric arcs. A large fraction of UV, including all that reaches the surface of the Earth, is classified as non-ionizing radiation. The UV spectrum thus has many effects, both beneficial and damaging, to human health.

  4. UVC in Healthcare • Background • Multiple-drug-resistant organisms (MDROs) and Clostridium difficile (CD) are significant problems in health care. Evidence suggests that these organisms are transmitted to patients by the contaminated environment. • Methods • This is a retrospective study of the implementation of ultraviolet environmental disinfection (UVD) following discharge cleaning of contact precautions rooms and other high-risk areas at Westchester Medical Center, a 643-bed tertiary care academic medical center. Incidence rates of hospital-acquired MDROs plus CD before and during the UVD use were evaluated using rate ratios and piecewise regression. • Results • The average time per UVD was 51 minutes, and machines were in use 30% of available time. UVD was used 11,389 times; 3,833 (34%) of uses were for contact precautions discharges. UVD was completed for 76% of contact precautions discharges. There was a significant 20% decrease in hospital-acquired MDRO plus CD rates during the 22-month UVD period compared with the 30-month pre-UVD period (2.14 cases/1,000 patient-days vs 2.67 cases per 1,000 patient-days, respectively; rate ratio, 0.80; 95% confidence interval: 0.73-0.88, P < .001). • Conclusion • During the time period UVD was in use, there was a significant decrease in overall hospital-acquired MDRO plus CD in spite of missing 24% of opportunities to disinfect contact precautions rooms. This technology was feasible to use in our acute care setting and appeared to have a beneficial effect.

  5. NEW TECHNOLOGIES (ATP) ATP METER- ATP stands for Adenosine Triphospate. This meter provides instant information in a janitorial inspection on how to clean the surface, which is done by measuring the levels of contamination. This meter is easily affordable and can be used in office buildings, schools, hospitals etc. The more the reading indicated on the meter, the more contaminated the surface is. The results shown by the meter is accurate and can act as a tool to maintain a clean, hygenic surface.

  7. NEW TECHNOLOGIES (UVC) UVC LIGHT AS A SANITIZER- For years UVC light has been used to kill bacteria in water and air, the technology now is being used bacteria on surfaces This is the IRIS UVC machine.

  8. NEW TECHNOLOGIES (UVC) • This is the TRU-D

  9. NEW TECHNOLOGIES • Glo Germ™ is a product sold both in liquid and powder form that contains proven safe ingredients formulated to be the same size as bacteria, basically 5 microns in size. When used in either the powder or liquid-based form, with the use of an ultra-violet light, it simulates the spread of germs, teaching how quickly and broadly germs can be spread in a short period of time

  10. Conclusion AS WE CONTINUE TO TRY AND COMBAT HAI’S (HOSPITAL AQUIRED INFECTIONS), UVC AND ATP TECHNOLOGIES ARE BEING USED IN THIS FIGHT. THESE TECHNOLOGIES WILL NOT WORK IF YOU DON’T HAVE A SOLID CLEANING PROGRAM.
