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 03/26/2010TSICP5 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

Prevent Transmission: Hand Hygiene Many facilities have had significant improvements Microbial resurgence is rapid following HH Logistical limitations in a complex environment 03/26/2010TSICP20
21
HH in Complex Intense Environments is Very Difficult 30 to 40 HH “Moments” per Hour during direct patient care
22
Isolation Difficult to implement and maintain When to Begin—When to stop Unintended consequences 03/26/2010TSICP22
23
Isolation is Difficult
24
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
25
What can we do?? Improve effectiveness of environmental cleaning/ disinfection patient environment
26
How Can We Evaluate Environmental Cleaning Direct observation Culture the environment ATP bioluminescence Tool Fluorescent marking tool 03/26/2010TSICP26
27
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.
28
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
29
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

Evaluating Patient Zone Environmental Hygiene
34
GOAL OF THE PROJECT To develop a surrogate marking system to evaluate the effectiveness of environmental cleaning/disinfection of the near-patient environment
35
Dazo Solution (Initially called “GOO”)
36
Target After Marking
37
Target Enhanced
38
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
39
Cleaned, empty room identified Room markedRoom evaluated Terminal cleaning after 1 or 2 patient cycles Phase I: Covert Baseline Environmental Cleaning Evaluation Phase II:A. Programmatic Analysis B. Educational Interventions – ES staff Cleaned, empty room identified Room markedRoom evaluated Terminal cleaning after 1 or 2 patient cycles Phase III: Re-evaluation of Cleaning and feedback to ES

Preliminary Results – Three Hospitals Clinical Infectious Diseases – February 2006
41
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 The Healthcare Environmental Hygiene Study Group
42
Healthcare Environmental Hygiene Study Group – Acute Hospitals (90) MA = 12 RI = 5
44
Baseline Environmental Evaluation of 36 Acute Care Hospitals % of Objects Cleaned Hospitals Mean = 48.5 % (20,056 Objects)

49
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 03/26/2010TSICP49
50
Focus Group Questions What recommendations do you have to improve cleaning outcomes? What barriers do you see that would prevent implementation of these recommendations? 03/26/2010TSICP50
51
Problems Identified Staffing not always adjusted to busiest times Pressure from nursing staff to “get it done” Supervisors not visible Staff on evening shift “on call” from one end of hospital to the other 03/26/2010TSICP51
52
Recommendations More “on the spot” feedback from supervisors Help from supervisors to prioritize work Better communication with nursing Consistency unit to unit Maintain level of cleaning done when TJC is expected Have a quality control officer Use Dazo as follow-up to classroom orientation Evaluation of work efficiencies (Organizational Improvement) 03/26/2010TSICP52
53
ICU Project Daily Clean of Isolation Rooms Marked room and read in or 2 days 03/26/2010TSICP53

Who is responsible for each item? -Siderail bed control-Table/counter/workspace -Call button-Computer keyboard -Tray table-Storage drawer handle -Monitor control-Room light switch -Vent control- Room door handles -Commode-IV pump -Sink
55
Item Responsibility Environmental Services: – Tray table – Light switch – Room door handles – Sink – Work surface – Cabinet handles – Call button – In-room commode ICU Nursing: – Keyboards – Side rails – IV pumps – Monitor control panel Respiratory Therapists: – Ventilator Control Panel Re-evaluation will take place in 3-4 weeks Re-evaluation will take place in 3-4 weeks

Impact of an Environmental Cleaning Intervention on the Risk of Acquiring MRSA and VRE from Prior Room Occupants (SHEA Abstract 273) 2009 Datta R, Platt R, Kleinman K, Huang SS
58
Brigham & Woman’s ICU Study Impact of an Environmental Cleaning Intervention on the Risk of Acquiring MRSA and VRE from Prior Room Occupants (SHEA Abstract 273) 2009 Datta R, Platt R, Kleinman K, Huang SS “For both MRSA and VRE, absolute risk appeared diminished during the intervention regardless of prior occupant status”
59
Conclusions It is likely that surfaces in the Patient Zone are of relevance in the transmission of Healthcare Associated Pathogens. While optimizing hand hygiene and isolation practice is clearly important there is no reason why the effectiveness and thoroughness of environmental hygienic cleaning should not also be optimized, particularly since such an intervention can be essentially resource neutral.
