Review Meta AnalysisExtended-spectrum β-lactamase-producing Enterobacteriaceae colonisation in long-term care facilities: a systematic review and meta-analysis.
The objectives of this study were to estimate the colonisation rate by extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE) among residents of long-term care facilities (LTCFs) and to identify pertinent risk factors. A systematic search of PubMed and EMBASE databases for studies published up to May 2016 that provided raw data for gastrointestinal colonisation by ESBL-PE among LTCF residents was performed. Twenty-three studies reporting data on 9775 screened subjects met the inclusion criteria. ⋯ Risk factors for colonisation included recent antibiotic use (within 6 months) [odds ratio (OR) = 2.06, 95% CI 1.78-2.38], previous hospitalisation (within 2.5 years) (OR = 1.50, 95% CI 1.04-2.15), history of invasive procedures (within 2 years) (OR = 2.79, 95% CI 1.66-4.70), previous ESBL-PE colonisation or infection (OR = 6.77, 95% CI 1.33-34.62), history of urinary tract infection (OR = 2.66, 95% CI 1.76-4.01) and urinary catheter use (OR = 2.55, 95% CI 1.29-5.04). In conclusion, almost one in five LTCF residents is colonised with ESBL-PE, and colonised residents are more likely to have a history of recent antibiotic use or healthcare facility utilisation. Strict adherence to antimicrobial stewardship in LTCFs is needed to address these high resistance rates.

Review Meta AnalysisBloodstream infections due to extended-spectrum β-lactamase-producing Enterobacteriaceae among patients with malignancy: a systematic review and meta-analysis.
Extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE) are an increasing cause of resistant infections among patients with malignancy. This study sought to estimate the prevalence of bloodstream infections (BSIs) caused by ESBL-PE in this population and to examine regional and temporal differences. The PubMed and EMBASE databases (to 30 April 2016) were searched to identify studies reporting ESBL-PE BSI rates among patients with malignancies. ⋯ Overall, ca. 1 in 10 BSIs in patients with malignancy is caused by ESBL-PE and in some areas this rate can be as high as 1 in 3 cases. Additionally, the incidence of these resistant infections is rising. These findings should be considered when selecting empirical antimicrobial therapy and should prompt strict adherence to antimicrobial stewardship.
