ABSTRACT
We analyzed the impact of a hospital tap water avoidance protocol on respiratory isolation of nontuberculous mycobacteria (NTM). After protocol implementation, hospital-onset episodes of respiratory NTM isolation on high-risk units decreased from 41.0 to 9.9 episodes per 10â 000 patient-days (incidence rate ratio, 0.24; 95% confidence interval, .17-.34; Pâ <â .0001).

Antibiotic stewardship is becoming a requirement for nursing homes. Programs should be interdisciplinary and multifaceted; should have support from nursing home administrators; and should aim to promote antibiotics only when needed, not just in case. Recommended components include use of evidence-based guidelines; ongoing monitoring of antibiotic prescriptions, cultures, and study results; monitoring of health outcomes; use of nursing home-specific antibiograms; regular reporting and feedback to medical providers and nurses; and education of residents and families.

In pharmaceutical compounding, strict adherence to a protocol for hand hygiene and glove sanitizing is essential to ensure the purity, safety, and effectiveness of sterile preparations; reduce patient morbidity and mortality; and decrease the cost of health care. Alcohols and chlorhexidine gluconate are among the most effective bactericides, virucides, and fungicides, and acquired resistance to those agents has not been shown in clinical practice. This article, which is part 1 in a series of 2, pertains primarily to alcohol-based hand rubs that are appropriate for use in sterile compounding (glove sanitizing is discussed as part of the handsanitizing process). In a brief overview of those products, we define pertinent terminology, examine the necessity of and requirements for the use of sanitizers, review their mechanism of action and composition, consider factors pertinent to their selection, and present a protocol for their application. In part 2 of this series, the topics examined include a comparison of various alcohol-based sanitizers and answers to compounders' frequently asked questions about their use.

Selecting an appropriate sanitizer (i.e., "rub") for application to hands and gloves before and, if necessary, during sterile compounding is as important as is its consistent and judicious use. Alcohols and chlorhexidine gluconate, which have long been recognized as safe and powerful biocides, are often essential ingredients in such sanitizing products. In this second article in a 2-part series on alcohol-based hand and glove sanitizers, we review the selection of and need for those rubs in sterile compounding, present considerations for their safe storage, compare the features of several appropriate sanitizing agents, and answer compounders' frequently asked questions about their use. Glove sanitizing is discussed as part of the hand-sanitizing process. In part 1 of this series, we explained, among other topics, the mechanism of action and composition of alcohol-based sanitizers and presented a protocol for their application to hands and gloves.

BACKGROUND: In 2017, our hospital was identified as a high outlier for postoperative Clostridium difficile infections (CDIs) in the American College of Surgeons NSQIP semi-annual report. The Department of Surgery initiated a CDI task force with representation from Surgery, Infectious Disease, Pharmacy, and Performance Services to analyze available data, identify opportunities for improvement, and implement strategies to reduce CDIs. STUDY DESIGN: Strategies to reduce CDIs were reviewed from the literature and the following multidisciplinary strategies were initiated: antimicrobial stewardship optimization of perioperative order sets to avoid cefoxitin and fluoroquinolone use was completed; penicillin allergy assessment and skin testing were implemented concomitantly; increased use of ultraviolet disinfectant strategies for terminal cleaning of CDI patient rooms; increased hand hygiene and personal protection equipment signage, as well as monitoring in high-risk CDI areas; improved diagnostic stewardship by an electronic best practice advisory to reduce inappropriate CDI testing; education through surgical grand rounds; and routine data feedback via NSQIP and National Healthcare Safety Network CDI reports. RESULTS: The observed rate of CDIs decreased from 1.27% in 2016 to 0.91% in 2017. Cefoxitin and fluoroquinolone use decreased. Clostridium difficile infection testing for patients on laxatives decreased. Terminal cleaning with ultraviolet light increased. Handwashing compliance increased. Data feedback to stakeholders was established. CONCLUSIONS: Our multidisciplinary CDI reduction program has demonstrated significant reductions in CDIs. It is effective, straightforward to implement and monitor, and can be generalized to high-outlier institutions.

OBJECTIVE: Describe the epidemiology of carbapenem-resistant Enterobacteriaceae (CRE) and examine the effect of lower carbapenem breakpoints on CRE detection. DESIGN: Retrospective cohort. SETTING: Inpatient care at community hospitals. PATIENTS: All patients with CRE-positive cultures were included. METHODS: CRE isolated from 25 community hospitals were prospectively entered into a centralized database from January 2008 through December 2012. Microbiology laboratory practices were assessed using questionnaires. RESULTS: A total of 305 CRE isolates were detected at 16 hospitals (64%). Patients with CRE had symptomatic infection in 180 cases (59%) and asymptomatic colonization in the remainder (125 cases; 41%). Klebsiella pneumoniae (277 isolates; 91%) was the most prevalent species. The majority of cases were healthcare associated (288 cases; 94%). The rate of CRE detection increased more than fivefold from 2008 (0.26 cases per 100,000 patient-days) to 2012 (1.4 cases per 100,000 patient-days; incidence rate ratio (IRR), 5.3 [95% confidence interval (CI), 1.22-22.7]; P = .01). Only 5 hospitals (20%) had adopted the 2010 Clinical and Laboratory Standards Institute (CLSI) carbapenem breakpoints. The 5 hospitals that adopted the lower carbapenem breakpoints were more likely to detect CRE after implementation of breakpoints than before (4.1 vs 0.5 cases per 100,000 patient-days; P < .001; IRR, 8.1 [95% CI, 2.7-24.6]). Hospitals that implemented the lower carbapenem breakpoints were more likely to detect CRE than were hospitals that did not (3.3 vs 1.1 cases per 100,000 patient-days; P = .01). CONCLUSIONS: The rate of CRE detection increased fivefold in community hospitals in the southeastern United States from 2008 to 2012. Despite this, our estimates are likely underestimates of the true rate of CRE detection, given the low adoption of the carbapenem breakpoints recommended in the 2010 CLSI guidelines.

Fifty interactions between healthcare workers and patients were observed to obtain a quantifiable definition of "high-touch" (ie, frequently touched) surfaces based on frequency of contact. Five surfaces were defined as high-touch surfaces: the bed rails, the bed surface, the supply cart, the over-bed table, and the intravenous pump.

Health care-associated infections (HAI) remain a major cause of patient morbidity and mortality. Although the main source of nosocomial pathogens is likely the patient's endogenous flora, an estimated 20% to 40% of HAI have been attributed to cross infection via the hands of health care personnel, who have become contaminated from direct contact with the patient or indirectly by touching contaminated environmental surfaces. Multiple studies strongly suggest that environmental contamination plays an important role in the transmission of methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus spp. More recently, evidence suggests that environmental contamination also plays a role in the nosocomial transmission of norovirus, Clostridium difficile, and Acinetobacter spp. All 3 pathogens survive for prolonged periods of time in the environment, and infections have been associated with frequent surface contamination in hospital rooms and health care worker hands. In some cases, the extent of patient-to-patient transmission has been found to be directly proportional to the level of environmental contamination. Improved cleaning/disinfection of environmental surfaces and hand hygiene have been shown to reduce the spread of all of these pathogens. Importantly, norovirus and C difficile are relatively resistant to the most common surface disinfectants and waterless alcohol-based antiseptics. Current hand hygiene guidelines and recommendations for surface cleaning/disinfection should be followed in managing outbreaks because of these emerging pathogens.
