A Multifaceted Approach in Reducing Healthcare Pathogens

  1. 1. A Multifaceted Approach in Reducing Healthcare Pathogens By Dr. Christopher Truitt
  2. 2. Chief Science Officer of, GERMBLAST Disclosure
  3. 3. “Nightmare bacteria” are trying to spread in the U.S., CDC says “The Flu Season Is the Worst in Nearly a Decade” Recent Headlines!
  4. 4. Importance: • 722,000 occurrences in 2011 in acute care hospitals • Approximately 75,000 deaths • Estimated cost of $9.8 billon (2012 dollars) Any given day 1 in 25 patients have at least one Healthcare-Associated Infection! Magill SS et al. N Engl J Med. 2014; 370:1198-1208. Zimlichman E et al. AMA Intern Med 2013; 173:2039-2046. The Problem: Healthcare- Associated Infections
  5. 5. Sources of Pathogens Causing HAIs 1. Weinstein RA. Am J Med. 1991; 91:(Suppl 3B):179S-184S. 2. Hayden et al. Infect Control Hosp Epidemiol. 2008; 29:149-154. 3. Stiefel et al. Infect Control Hosp Epidemiol. 2011; 32:185-187. 4. Guerrero et al. Am J Infect Control. 2012; 40:556-558. Reservoirs1 • Endogenous microflora- approx. 50% • Cross infection via hands of healthcare personnel (HCP)- approx. 30% • Environmental surfaces- approx. 20% Potential Contamination from HCP • 52% acquired VRE on hands2 • 45% acquired MRSA on hands3 • 50% acquired C. difficile on hands4
  6. 6. Increased HAI Acquisition Risk from Prior Room Occupant 0% 100% 200% 300% 400% Huang Hardy Dress Shaugnessy Datta Nseir Nseir MRSA MRSA C. difficile MRSA Pseudomonas Acinetobacter Mean = 120% Increased Risk of Acquisition (%) Carling P et al. Am J Infect Control. 2013 Nov; 41:S20-S25. VRE

  10. 10. The Solution: Multifaceted Approach Environmental Disinfection Staff Education/ Training Stakeholder Awareness Data Collection/ Analysis
  11. 11. Microfiber breaks down biofilms and physically removes dirt and microbes Embedded with silver or copper ions to enhance antimicrobial properties of fiber Environmental Disinfection- Microfiber
  12. 12. Focus on high contact areas from multiple users Common areas: • Door knobs or push plates, chairs, sinks, fixtures, desks, railings, OR suites, nursing stations, etc. Uncommon areas: • IV Poles, dispensers, and Kleenex boxes A targeted disinfectant cleaning approach can significantly decrease the spread of disease from the environment Critical Touch Points
  13. 13. Emerging Technologies Tablets/Phone Disinfection UV Light Chemicals Steam Aerosolized Hydrogen Peroxide Biostatic Polymers Photocatalytic Oxidation (PCO)
  14. 14. When innovative technology is combined with traditional cleaning practices, the result is a high level of disinfection Environmental Disinfection- Potential Results
  15. 15. Data Collection and Analysis Adenosine Triphosphate (ATP) Sampling • Quantitative rapid results • Can be linked to data tracking software • Provides quantitative data to make decisions prior to any illness or outbreak
  16. 16. Environmental ATP Data Allows analysis over time to find areas for improvement Useful to improve training Eliminates opportunities for illness/infection 0 125 250 375 500 RelativeLightUnits(RLU) Average ATP Data
  17. 17. Environmental Data Use Allows detection of high environmental values • Improper disinfection process • Personel changes Ability to respond to abnormal values quicker, potentially preventing unwanted illness 134 157 187 132 256 149 0 65 130 195 260 325 RelativeLightUnits(RLU) Average ATP Data
  18. 18. Staff Education Hand Hygiene Proper Chemical Usage Antimicrobial Stewardship Chain of Infection
  19. 19. Stakeholder Awareness Creating an awareness within all stakeholders that each play a role in keeping the fight outside the body
