ABSTRACT Patients with inflammatory bowel disease (IBD), namely ulcerative colitis (UC) and Crohns disease (CD), have worse outcomes with Clostridium difficile infection (CDI), including increased readmissions, colectomy, and death. Oral vancomycin is recommended for the treatment of severe CDI, while metronidazole is the standard of care for nonsevere infection. We aimed to assess treatment outcomes of CDI in IBD. We conducted a retrospective observational study of inpatients with CDI and IBD from January 2006 through December 2010. CDI severity was assessed using published criteria. Outcomes included readmission for CDI within 30 days and 12 weeks, length of stay, colectomy, and death. A total of 114 patients met inclusion criteria (UC, 62; CD, 52). Thirty-day readmissions were more common among UC than CD patients (24.2% versus 9.6%; P = 0.04). Same-admission colectomy occurred in 27.4% of UC patients and 0% of CD patients (P < 0.01). Severe CDI was more common among UC than CD patients (32.2% versus 19.4%; P = 0.12) but not statistically significant. Two patients died from CDI-associated complications (UC, 1; CD, 1). Patients with UC and nonsevere CDI had fewer readmissions and shorter lengths of stay when treated with a vancomycin-containing regimen compared to those treated with metronidazole (30-day readmissions, 31.0% versus 0% [P = 0.04]; length of stay, 13.62 days versus 6.38 days [P = 0.02]). Patients with UC and nonsevere CDI have fewer readmissions and shorter lengths of stay when treated with a vancomycin-containing regimen relative to those treated with metronidazole alone. Patients with ulcerative colitis and CDI should be treated with vancomycin.

Importance Although quality improvement (QI) interventions can reduce central-line-associated bloodstream infections (CLABSI) and catheter-related bloodstream infections (CRBSI), their economic value is uncertain. Objective To systematically review economic evaluations of QI interventions designed to prevent CLABSI and/or CRBSI in acute care hospitals. Evidence Review A search of Ovid MEDLINE, Econlit, Centre for Reviews & Dissemination, New York Academy of Medicines Grey Literature Report, Worldcat, prior systematic reviews (January 2004 to July 2016), and IDWeek conference abstracts (2013-2016), was conducted from 2013 to 2016. We included English-language studies of any design that evaluated organizational or structural changes to prevent CLABSI or CRBSI, and reported program and infection-related costs. Dual reviewers assessed study design, effectiveness, costs, and study quality. For each eligible study, we performed a cost-consequences analysis from the hospital perspective, estimating the incidence rate ratio (IRR) and incremental net savings. Unadjusted weighted regression analyses tested predictors of these measures, weighted by catheter-days per study per year. Findings Of 505 articles, 15 unique studies were eligible, together representing data from 113 hospitals. Thirteen studies compared Agency for Healthcare Research and Quality-recommended practices with usual care, including 7 testing insertion checklists. Eleven studies were based on uncontrolled before-after designs, 1 on a randomized controlled trial, 1 on a time-series analysis, and 2 on modeled estimates. Overall, the weighted mean IRR was 0.43 (95% CI, 0.35-0.51) and incremental net savings were

464 000; P < .001). Infections and net costs declined when hospitals already used checklists or had baseline infection rates of 1.7 to 3.7 per 1000 catheter-days. Study quality was not associated with effectiveness or costs. Conclusions and Relevance Interventions related to central venous catheters were, on average, associated with 57% fewer bloodstream infections and substantial savings to hospitals. Larger initial investments may be associated with greater savings. Although checklists are now widely used and infections have started to decline, additional improvements and savings can occur at hospitals that have not yet attained very low infection rates.

Gastrointestinal endoscopes are used for diagnostic and therapeutic purposes and are the most common medical device implicated in health care-associated outbreaks. Infections can be divided into endogenous or exogenous. Exogenous infections were associated with lapses in reprocessing. Recent outbreaks have occurred despite compliance with reprocessing guidelines and highlight the challenges with clearance of all organisms from the duodenoscopes and the potential role of biofilms in hindering adequate reprocessing. This review provides an overview of recent developments and the current understanding of the key contributing factors related to gastrointestinal endoscope-related infections and current approaches to identify and prevent these complications.
