AbstractBackground:Although guidelines for multidrug-resistant organisms generally include recommendations for contact precautions and surveillance cultures, it is not known how frequently U.S. hospitals implement these measures on a routine basis and whether infectious diseases consultants endorse their use.Methods:The Emerging Infections Network surveyed its members, infectious diseases consultants, to assess their use of and support for contact precautions and surveillance cultures for routine management of multidrug-resistant organisms in their principal inpatient workplace. Specifically, members were asked about use of these strategies for methicillin-resistantStaphylococcus aureus, vancomycin-resistant enterococci, and multidrug-resistant, gram-negative bacilli on general wards, ICUs, and transplant units.Results:Overall, 400 (86%) of 463 respondents supported the routine use of contact precautions to control one or more multidrug-resistant organisms in at least one unit, and 89% worked in hospitals that use them. In contrast, 50% of respondents favored routine use of surveillance cultures to manage at least one multidrug-resistant organism in any unit, and 30% of respondents worked in hospitals that use them routinely in any unit. Members favored routine use of surveillance cultures significantly more in ICUs and transplant units than in general wards for each multidrug-resistant organism (P<.001).Conclusions:Most of the infectious diseases consultants endorsed the use of contact precautions for routine management of patients colonized or infected with multidrug-resistant organisms and work in hospitals that have implemented them. In contrast, infectious diseases consultants are divided about the role of routine surveillance cultures in multidrug-resistant organism management, and few work in hospitals that use them.

Silver Nps

Growing resistance to currently approved antibiotics is posing serious concern worldwide. The multidrug-resistant organisms are a major cause of mortality and morbidity around the globe. The limited options to treat infections caused by resistant organism requires alternative strategies to increase the effectiveness of antibiotic for better clinical outcomes. Recent advances in nanotechnology have enabled the drugs to be used in nanoscale to increase the effectiveness of antibiotics. The use of nanoparticles to treat infectious diseases has a long history in the pharmaceutical market, and the versatility of these particles to incorporate various materials as carriers make it an attractive option to combat the current crisis of emerging antibacterial resistance. Silver, a metal with many medical applications, has inherent antimicrobial properties. Therefore, silver NPs are appearing as one of the best options to be used in combination with antibiotics to increase effectiveness against resistant bacteria. Here, we discuss the applications and mechanisms of silver NPs to treat microbial resistance in light of recent research.

After Hurricane Katrina, 50 patients were evacuated to Grady Memorial Hospital in Atlanta, Georgia, with limited medical records. The infection control department ordered contact precautions for 16 Patients. Surveillance cultures performed on admission identified colonization with multidrug-resistant (MDR) bacteria in 9 patients (18%). Presence of a wound was the strongest predictor for MDR colonization. More data are needed to reliably predict MDR bacterial colonization.

Accepted Practice

An accepted practice for patients colonized with multidrug-resistant organisms is to discontinue contact precautions following 3 consecutive negative surveillance cultures. Our experience with surveillance cultures to detect persistent carbapenemase-producing Enterobacteriaceae (CPE) colonization suggests that extrapolation of this practice to CPE-colonized patients may not be appropriate.Infect Control Hosp Epidemiol 2015;36(7):835–837

The Impact

Background: The rate of multidrug-resistant organisms (MDRO) colonisation in dialysis populations has increased over time. This study aimed to assess the effect of contact precautions and isolation on quality of life and mood for haemodialysis (HD) patients colonised with MDRO. Methods: Patients undergoing facility HD completed the Kidney Disease Quality of Life (KDQOL–SFTM), Beck Depression Inventory (BDI) and Personal Wellbeing-Index Adult (PWI-A). Patients colonised with MDRO were case-matched by age and gender with patients not colonised. Results: A total of 16 MDRO-colonised patients were matched with 16 controls. Groups were well matched for demographics and co-morbidities, other than a trend for older dialysis vintage in the MDRO group [7.2 years (interquartile range 4.6–10.0) compared to 3.2 (1.4–7.6) years, p=0.05]. Comparing MDRO-positive with negative patients, physical (30.5±10.7 vs. 34.6±7.3; p=0.2) and mental (46.5±11.2 vs. 48.5±12.5; p = 0.6) composite scores were not different between groups. The MDRO group reported poorer sleep quality (p=0.01) and sleep patterns (p=0.05), and lower social function (p=0.02). BDI scores were similar (MDRO-positive 10(3.5–21.0) vs. MDRO-negative 12(6.5–16.0), p=0.6). PWI-A scores were also similar in both groups; however, MDRO patients reported lower scores for “feeling safe”, p=0.03. Conclusion: While overall scores of quality of life and depression were similar between groups, the MDRO group reported poorer outcomes in sleep and social function. A larger cohort and qualitative interviews may give more detail of the impact of contact precautions and isolation on HD patients. The necessity for contact precautions for different MDRO needs consideration.

Carbapenem Resistant Enterobacteriaceae

Background: With increasing medical tourism and international healthcare, emerging multidrug resistant organisms (MDROs) or “superbugs” are becoming more prevalent. These MDROs are unique because they are resistant to antibiotics and can carry special resistance mechanisms. In April 2019, our hospital was notified that a superbug, New Delhi Metallo-β-lactamase(NDM)–producing carbapenem-resistant Enterobacteriaceae (CRE), was identified in a patient who had been transferred to another hospital after being at our hospital for 3 weeks. Our facility had a CRE admission screening protocol in place since 2013, but this patient did not meet the criteria to be screened on admission. Methods: The infection prevention (IP) team consulted with the Minnesota Department of Health (MDH) and gathered stakeholders to discuss containment strategies using the updated 2019 CDC Interim Guidance for Public Health Response to Contain Novel or Targeted Multidrug-resistant Organisms (MDROs) to determine whether transmission to other patients had occurred. NDM CRE was classified under tier 2 organisms, meaning those primarily associated with healthcare settings and not commonly identified in the region, and we used this framework to conduct an investigation. A point-prevalence study was done in an intensive care unit that consisted of rectal screening of 7 patients for both CRE and Candida auris, another emerging MDRO. These swabs were sent to the Antibiotic Resistance Laboratory Network (ARLN) Central Regional Lab at MDH for testing. An on-site infection control risk assessment was done by the MDH Infection Control Assessment and Response (ICAR) team. Results: All 7 patients were negative for both CRE and C. auris, and no further screening was done. During the investigation, it was discovered that the patient had had elective ambulatory surgery outside the United States in March 2019. The ICAR team assessment provided overall positive feedback to the nursing unit about isolation procedures, cleaning products, and hand hygiene product accessibility. Opportunities included set-up of soiled utility room and updating our process to the 2019 MDH recommendation to screen patients for CRE and C. auris on admission who have been hospitalized, had outpatient surgery, or hemodialysis outside the United States in the previous year. Conclusions: Point-prevalence study results showed no transmission of CRE and highlighted the importance of standard precautions. This event supports the MDH recommendation to screen for CRE any patients who have been hospitalized, had outpatient surgery, or had hemodialysis outside the United States in the previous year.Funding: NoneDisclosures: None

Multidrug-resistant organism infections have become important in recent years due to the increased prevalence of diabetic foot ulcers and their possible consequences. This study aimed to systematically review and evaluate ulcer duration, healing time, hospital stay, amputation, and mortality rates in patients with diabetic foot ulcers caused by infection with multidrug-resistant organisms. PubMed, the Cochrane Library, and Web of Science were searched in May 2020 to find observational studies in English about the clinical outcomes of multidrug-resistant organism infection in diabetic foot ulcers. Eight studies met the inclusion criteria, and these studies included 923 patients. The overall methodological quality of the study was moderate. Ulcer duration was described in six studies, and there was no practical association with multidrug-resistant organisms. Two out of three studies reported a longer healing time in multidrug-resistant organism infections than in non-multidrug-resistant organism infections. Clinical outcomes included the duration of hospitalisation, surgeries, amputations, and deaths. Lower limb amputation was the most reported clinical outcome in the included studies, and was more prevalent in the multidrug-resistant organism infections. We concluded that there was not enough evidence that multidrug-resistant organisms hindered the healing of diabetic foot ulcers. In contrast to the clinical outcomes, multidrug-resistant organisms affect both amputation rates and mortality rates.
