Is Your Facility Clean?DAZO Knows Sandra Von Behren TSICP
Objectives • Discuss the role of the environment in the transmission of healthcare-associated infections (HAIs) and multi-drug resistant organisms (MDROs) • Identify available methods to evaluate environmental cleanliness • Discuss strategies to improve environmental cleaning and decrease the risk of MDRO and HAI transmission TSICP

The Environment as a Source of Pathogens • S. aureus • Dancer et al; JHI 2006; 62: 200-206 • MRSA • Boyce et al, ICHE 1997; 18:622-627 • VRE • Bhalla et al, ICHE 2004; 25: 164-167 • Hayden, et al, ICHE 2008; 29: 149-154 TSICP
Environmental Contamination: Is There A Link to HAI Acqusition? Patients admitted to rooms previously occupied by patients with MRSA, VRE, Acinetobacter baumanii are at risk of acquiring organisms from the environment Huang, et al; Arch Intern Med 2006; 166: 1945-1951 Hardy , et al; ICHE 2006; 27: 127-132 Sexton et al; JHI 2006; 62: 187-194 Martinez, et al; Arch Intern Med 2003; 163: 1905-1912 TSICP

Prevent Transmission:Hand Hygiene • Many facilities have had significant improvements • Microbial resurgence is rapid following HH • Logistical limitations in a complex environment TSICP
HH in Complex Intense Environments is Very Difficult 30 to 40 HH “Moments” per Hour during direct patient care
Isolation • Difficult to implement and maintain • When to Begin—When to stop • Unintended consequences TSICP
Our review of the literature demonstrates that contact precautions have unintended consequences that are potentially deleterious to the patient. Measures to ameliorate these deleterious consequences of contact precautions are urgently needed. Am J Infect Control. 2009 (May); 37: 85-91
What can we do?? Improve effectiveness of environmental cleaning/ disinfection patient environment
How Can We Evaluate Environmental Cleaning • Direct observation • Culture the environment • ATP bioluminescence Tool • Fluorescent marking tool TSICP
ATP bioluminescence Swab surface luciferase tagging of ATP Hand held luminometer Used in the commercial food preparation industry to evaluate surface cleaning before reuse and as an educational tool for more than 30 years.
ATP Bioluminescence Testing in Healthcare Settings Potential usefulness: Has been used as a surrogate for environmental culturing Provides an estimate of cleanliness Can rapidly define how clean an object is…. but non-microbial ATP is also evaluated Standards to optimize predictive values are still being evaluated Can be used to do one-on-one education of ES staff
ATP Bioluminescence Testing in Healthcare Settings Potential limitations: Secondary cleaning of the site is required to remove disinfectant induced signal decay or enhancement. Involvement of the ES staff is implicit since evaluation must be done within minutes of cleaning. Pre-intervention evaluation of disinfection cleaning is difficult without inducing a Hawthorne effect Results are individual ES staff / time specific. Many manufacturers of luminometers and ATP swabs makes interinstitutional standardization difficult
GOAL OF THE PROJECT To develop a surrogate marking system to evaluate the effectiveness of environmental cleaning/disinfection of the near-patient environment
The Targeting Solution • A mixture of several glues, soaps and a targeting dye which: • Dries rapidly • Remains stable • Easily removed with light abrasion and damp cloth • Inconspicuous
Terminal cleaning after 1 or 2 patient cycles Cleaned, empty room identified Room marked Room evaluated Phase I: Covert Baseline Environmental Cleaning Evaluation Terminal cleaning after 1 or 2 patient cycles Cleaned, empty room identified Room marked Room evaluated Phase II: A. Programmatic Analysis B. Educational Interventions – ES staff Phase III: Re-evaluation of Cleaning and feedback to ES
Preliminary Results – Three Hospitals Clinical Infectious Diseases – February 2006
The Healthcare Environmental Hygiene Study Group On the basis of our preliminary results and presentations at SHEA, APIC and ICAAC conferences we have gathered together a group of hospitals to further evaluate the tool and process improvement programs
Healthcare Environmental Hygiene Study Group – Acute Hospitals (90) MA = 12 RI = 5
Baseline Environmental Evaluation of 36 Acute Care Hospitals Mean = 48.5 % Hospitals (20,056 Objects) % of Objects Cleaned
PROPORTION OF OBJECTS CLEANED AS PART OF TERMINAL ROOM CLEANING IN 20 ACUTE CARE HOSPITALS %
Terminal Room Cleaning Project – Three Programmatic Responses 17 HOSPITALS 10 HOSPITALS 8 HOSPITALS
Hospitals Environmental Hygiene Study Group36 Hospital Results % of Objects Cleaned PRE INTERVENTION POST INTERVENTION Resource Neutral P = <.0001
Specific Opportunities for Improvement • TERMINAL ROOM CLEANING • INFECTION PREVENTION • TARGETS • Sink and Faucets • Toilet Surfaces • Toilet Flush Handle • Bedpan Cleaner • Toilet Area Handholds • Toilet Area Door Knobs or • Push Plates • Bedside Table • Tray Table • Patient Chair • Side Rails • Room Door Knobs • Call Box • Telephone • Bathroom Light Switches
Focus Group • Held 4 meetings with Environmental Services (EVS) staff on different shifts • 5-6 staff members in each session • Met for 4 hours • No EVS supervisors present • Meal provided TSICP
Focus Group Questions • What recommendations do you have to improve cleaning outcomes? • What barriers do you see that would prevent implementation of these recommendations? TSICP
