Template for an antibiotic stewardship policy for post-acute and long-term care settings.
To support compliance with Centers for Medicare and Medicaid services (CMS) requirements and aid facilities in establishing a stewardship program, the Infection Advisory Committee at the American Medical Directors Association -The Society for Post-Acute and Long-Term Care Medicine, has developed an antibiotic stewardship policy template tailored to the long-term care setting. This paper describes that policy template.

Clostridium difficile colonization of nursing home residents.
This letter to the editor notes that Clostridum difficile is a leading cause of infectious diarrhea in nursing homes and asserts that evidence-based infection control guidelines are needed to reduce transmission of C. difficile in these settings.

Loop ileostomy versus total colectomy as surgical treatment for Clostridium difficile-associated disease: an Eastern Association for the Surgery of Trauma multicenter trial.
The objective of this study was to compare loop ileostomy (LI) and total colectomy (TC) procedures in a multicentric approach to help the surgeon decide what procedure was best suited for the patient in need. In this study, the investigators found that LI carried less mortality than TC.

Risk of Clostridium difficile infection in hematology-oncology patients colonized with toxigenic C. difficile.
This study determined that the prevalence of colonization with toxigenic Clostridium difficile among patients with hematological malignancies and/or bone marrow transplant at admission to a 566-bed academic medical care center was 9.3 percent. Thirteen percent of colonized patients developed symptomatic disease during hospitalization. This population may benefit from targeted C. difficile infection control interventions.

Using clinical scenarios to understand preventability of Clostridium difficile infections by inpatient antibiotic stewardship programs.
The authors of this research brief designed a 2-phase study (1) to define the types of clostridium difficile infections (CDI) that clinicians consider unlikely preventable by inpatient antibiotic stewardship programs and (2) to estimate the relative proportion of inpatient CDI cases at a tertiary-care hospital that belongs to this category of “nonpreventable” CDI.

Identification of novel risk factors for community-acquired Clostridium difficile infection using spatial statistics and geographic information system analyses.
The rate of community-acquired Clostridium difficile infection (CA-CDI) is increasing. While receipt of antibiotics remains an important risk factor for CDI, studies related to acquisition of C. difficile outside of hospitals are lacking. This study found that proximity to a livestock farm (0.01), proximity to farming raw materials services (0.02), and proximity to a nursing home (0.04) were independently associated with increased rates of CA-CDI.

Are hospital floors an underappreciated reservoir for transmission of health care-associated pathogens?
In a survey of 5 hospitals, the researchers found that floors in patient rooms were frequently contaminated with pathogens and high-touch objects such as blood pressure cuffs and call buttons were often in contact with the floor. Contact with objects on floors frequently resulted in transfer of pathogens to hands.

Enhanced terminal room disinfection and acquisition and infection caused by multidrug-resistant organisms and Clostridium difficile (the Benefits of Enhanced Terminal Room Disinfection study): a cluster-randomised, multicentre, crossover study.
The researchers determined the effects of three enhanced strategies for terminal room disinfection (disinfection of a room between occupying patients) on acquisition and infection due to methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, C difficile, and multidrug-resistant Acinetobacter. They found that the incidence of target organisms among exposed patients was significantly lower after adding UV (quaternary ammonium disinfectant and disinfecting ultraviolet [UV-C]) light to standard cleaning strategies.

Teaching health care workers to adopt a systems perspective for improved control and prevention of health care-associated infections.
The authors argue that procedural approaches alone, even with high levels of adherence, are often insufficient to solve the growing problem of health care-associated infections (HAIs); it is equally important that interventions address the more complex cognitive aspects of HAI control and prevention. Health care workers (HCWs) face many patient care situations for which standard procedures have not been and cannot be developed.

The burden of Clostridium difficile infection: estimates of the incidence of CDI from U.S. administrative databases.
The researchers used comparable methods with multiple administrative databases to compare the incidence of clostridium difficile infection (CDI) in older and younger persons in the United States. They found that the incidence of CDI was 10-fold lower and the proportion of community-onset CDI was much higher in the privately insured younger LabRx population compared to the elderly Medicare population.

Inappropriate antibiotic use and gastric acid suppression preceding Clostridium difficile infection.
To understand how often Clostridium difficile infection (CDI) is related to inappropriate medication use, the researchers evaluated appropriateness of antimicrobial therapy and gastric acid suppression preceding CDI acquired. Of all CDI episodes, 38.0 percent (27 of 71) were preceded by inappropriate gastric acid suppressant medications. For the 40 episodes in which gastric acid suppressant medications were used prior to CDI, 27 (67.5 percent) were inappropriately treated.

Identification of Medicare recipients at highest risk for Clostridium difficile infection in the US by population attributable risk analysis.
This study determined the population attributable risk percent (PAR%) for Clostridium difficile infection (CDI) in various subpopulations in the Medicare 5% random sample. It found that small and identifiable subpopulations that account for relatively large proportions of CDI cases in the elderly were identified. These data can be used to target specific subpopulations for CDI prevention interventions.

Investigation to identify a resource-efficient case-control methodology for determining antibiotics associated with Clostridium difficile infection.
This study consisted of a series of case-control studies involving two groups of patients admitted to the hospital, the first group with clostridium difficile infection (CDI), and a control group without CDI. The purpose was to determine the relationship between the use of antibiotics and the presence of CDI. A simple matching strategy was found to be an efficient and feasible compromise strategy to identify high-risk antibiotics associated with CDI.

Lessons learned from implementing Clostridium difficile-focused antibiotic stewardship interventions.
The researchers sought to determine whether controlling the prescription of targeted antibiotics would translate to a measurable reduction in hospital-onset Clostridium difficile infection (CDI) rates. They found that decreases in target antibiotic consumption did not translate into reductions of hospital-onset CDI in this study, but many valuable lessons were learned.

Sensitive and selective culture medium for detection of environmental Clostridium difficile isolates without requirement for anaerobic culture conditions.
The researchers developed a low-cost selective broth medium containing thioglycolic acid and L-cystine, termed C. difficile Brucella broth with thioglycolic acid and L-cystine (CDBB-TC), for the detection of C. difficile from environmental specimens under aerobic culture conditions. Their findings demonstrate that a broth medium containing thioglycolic acid and L-cystine provides a sensitive and selective method for the culture of C. difficile from environmental specimens without the need for anaerobic culture conditions.

Use of data envelopment analysis to quantify opportunities for antibacterial targets for reduction of health care-associated Clostridium difficile infection.
The authors conducted a cross-sectional study using claims data from 58 hospitals to create a benchmark strategy targeting high-risk antibacterials for C difficile. Seventeen hospitals were identified as best-practice hospitals. They found that the antibacterial classes requiring the greatest percentage reduction in use in non-best-practice hospitals versus best-practice hospitals were clindamycin, β-lactam/β-lactamase combinations, and carbapenems.
