Identifying Opportunities to Enhance Environmental Cleaning in 23 Acute Care Hospitals. Infect Control Hosp Epidemiol 2008;29:1-7

PC Carling and others cite studies that indicate that the hospital environment has a role in the transmission of healthcare-associated pathogens, specifically strains of VRE, MRSA and Acinetobacter baumannii. A review of research that used molecular epidemiology to distinguish between strains led to the conclusion that suboptimal environmental cleaning possibly plays an important role in the spread of healthcare-associated pathogens. To evaluate the thoroughness of terminal room cleaning, the authors used a novel targeting method in 23 acute care hospitals.

Fourteen high risk objects (sink, toilet seat, tray table, bedside table, toilet handle, side rail, call box, telephone, chair, toilet door knobs, toilet handhold, bedpan cleaner, room door knobs, and bathroom light switch, defined as high risk objects based on 21 studies) were evaluated by the hospitals. A transparent, easily cleaned, environmentally stable solution that fluoresces when exposed to ultraviolet light was used on the identified surfaces in patient rooms and bathrooms. The overall thoroughness of terminal cleaning, expressed as a percentage of surfaces evaluated, was 49% (range 35%-81%). However, there was greater variation for some specific high risk objects: toilet handholds, bedpan cleaners, light switches, and door knobs (30%, range 0%-90%). Sinks, toilet seats, and tray tables were relatively well cleaned (over 75%). The lack of optimal cleaning for certain objects such as bedpan cleaners, toilet area handholds, and doorknobs, may result from lack of appreciation of the role that these objects have in transmitting healthcare-associated pathogens. Education and performance feedback may result in improvement in cleaning in some facilities. However, in hospitals where no objects were cleaned well, problems that include inadequate staffing, motivation issues, and inadequate supervision need to be considered.

The importance of appropriate environmental cleaning is evident in two recent documents. The Centers for Disease Control and Prevention Healthcare Practices Advisory Committee guideline, Management of Multi-Resistant Organisms in Healthcare Settings, 2006, strongly recommends (Category 1B) that hospitals “monitor (i.e., supervise and inspect) cleaning performance to ensure consistent cleaning and disinfection of surfaces in close proximity to the patient and those likely to be touched by the patient and healthcare provider.” In addition the Institute for Healthcare Improvement document on reducing methicillin-resistant Staphylococcus aureus says that hospitals should “use immediate feedback mechanisms to assess cleaning and reinforce proper technique.” Carling et al. provide a targeting method for facilities to secure data on cleaning and disinfection and then provide appropriate interventions to improve practice.

 

QUESTION OF THE MONTH

Q: Are there any guidelines for the removal of Contact Precautions for patients with MRSA in hospitals?

A: Staphylococcus aureus, including those strains that are methicillin and oxicillin resistant, frequently colonizes humans and is considered normal flora. S. aureus can be found in respiratory secretions, skin, vaginal secretions, and stool and colonization often lasts for months to years. Importantly, Staphylococcus aureus is capable of being transmitted in the carrier state. One study demonstrated patients remain MRSA positive 6 months to 2 years (60 to 13 percent, respectively). 1 Scanvic found 40% of previous MRSA positive patients were still carriers on readmission at 3 months, and the median time to a negative MRSA screen was 8.5 months. Interestingly, of the 19 persistent carriers tested, 79% had PFGE patterns similar to previous isolates. In a multivariate analysis only the presence of a break in the skin was significantly associated with persistent carriage p=.0042. Currently, in addition to using Contact Precautions (CP), control measures may include active surveillance for early identification and isolation. Discontinuing precautions too soon may increase the risk of transmission within a healthcare facility. The CDC 2006 Guidelines for Management of Multidrug- Resistant Organisms in Healthcare Settings has no recommendations for when to discontinue Contact Precautions and make it an "Unresolved Issue". In the Background section of the MDRO Guidelines, it is discussed that, "in general it seems reasonable to discontinue Contact Precautions when three or more surveillance cultures for the targeted MDROs are repeatedly negative over the course of a week or two in patients who have not received antimicrobial therapy for several weeks, especially in the absence of a draining wound, profuse respiratory secretions, or evidence implicating the specific patient in ongoing transmission of the MDRO within the facility".

At UNC Health Care, the policy for discontinuing CP for patients with MRSA has recently changed. The UNC policy states that patients must first be off antibiotics for a minimum of one week, and extends to three weeks if on dialysis. Three negative cultures from the original site and from the nares are to be obtained one week apart. PCR can substitute for the nasal culture. Finally, decolonization therapy does not alter the protocol. This a change from what had become the standard of practice in most HCFS of waiting only 48 to 72 hours off antibiotics and cultures obtained a day apart times two. The change is based on multiple studies that have shown persons can stay colonized with MRSA for long periods of time and that carriage can be intermittent.

REGULATORY/LEGISLATIVE

NC Study law 1738 for Mandatory Reporting of HAI Redone by Legislature

On August 2nd, 2007, NC General Assembly ratified House Bill 1738 to establish the advisory commission on the public reporting of hospital infection rates.  The link to the ratified bill can be found on the NC Legislative website: http://www.ncleg.net/Sessions/2007/Bills/House/HTML/H1738v3.html .

The North Carolina legislature, through their rules, can redo laws previously enacted. Thus, in a meeting convened on April 2, 2008, they changed the NC HAI study law 1738 from formation of an advisory commission to an advisory committee co-chaired by legislators with no governor appointees, and no public health membership. The advisory committee has not met yet although all appointments have been made. The deadline for the final report on the committee's recommendations is December 31, 2008 .

Speaker Hackney has made two appointments to the Joint Study Committee on Hospital Infection Control and Disclosure. The two House members appointed join the four appointees already appointed to the Advisory Commission on Hospital Infection Control and Disclosure. Similarly the Senate President, Senator Marc Basnight appointed 2 legislators to join the Senate's previous appointments for a total of 12 members (all listed below).

Speaker of the House Appointments:
Representative Martha Alexander, Co-Chair
Representative Lucy T. Allen
Ms. Jayne P. Lee, Moore County
Dr. Christopher T. Aul, Cumberland County
Dr. William A. Rutala, Orange County
Ms. Marina B. Barber, Orange County

Speaker Pro Tem Appointments:
Senator William Purcell, Co-Chair
Senator Doug Berger
Dr. Keith Ramsey, Pitt County
Ms. Robin Carver, Johnston County
Dr. Dan Sexton, Durham County
Mr. Jay Currin, Cumberland County
