Appropriate use of antimicrobials in health care continues to be a challenge. Reliable and reproducible antimicrobial susceptibility testing methods are necessary to provide the clinician with valuable information that can be translated into positive clinical outcomes at the bedside. However, there are nuances with these testing methods that, if unrecognized, could lead to misinterpretation of results and inappropriate antibiotic selection. This primer describes the common antimicrobial susceptibility tests used in the clinical microbiology laboratory and reviews how subtle differences in testing methods and technique can influence reported results. Clinicians who have a thorough understanding of qualitative and quantitative methods, automated susceptibility testing systems, and commonly used screening and confirmatory tests for antibiotic-resistant organisms can strengthen institutional antibiotic stewardship programs and improve patient outcomes.
Increasingly, demands are placed on healthcare systems to meet antimicrobial stewardship standards and reporting requirements. This trend, combined with reduced financial and personnel resources, has created a need to adopt information technology (IT) to help ease these burdens and facilitate action. The incorporation of IT into an antimicrobial stewardship program can help improve stewardship intervention efficiencies and facilitate the tracking and reporting of key metrics, including outcomes. This paper provides a review of the stewardship-related functionality within these IT systems, describes how these platforms can be used to improve antimicrobial use, and identifies how they can support current and potential future antimicrobial stewardship regulatory and accreditation standards. Finally, recommendations to help close the gaps in existing systems are provided and suggestions for future areas of development within these programs are delineated.
Rapid diagnostic technologies (RDTs) significantly reduce organism identification time and can augment antimicrobial stewardship program (ASP) activities. An electronic survey quantified familiarity with and utilization of RDTs by clinical pharmacists participating in ASPs. Familiarity was highest with polymerase chain reaction (PCR). Formal infectious diseases training was the only significant factor influencing RDT familiarity. Infect Control Hosp Epidemiol 2017;38:863-866.
AbstractIn a study of 121 hospitals from 38 US states, 44% had access to an allergist for inpatient consultations and 39% had access to inpatient penicillin skin testing, indicating that the majority of US hospitals lack sufficient resources to address inpatient penicillin allergies.
It has been more than 60 years since Alexander Fleming discovered the drug that came to be known as penicillin. Antibiotics are now one of the most frequently used medications in the United States and are prescribed by medical professionals in almost every specialty. The past decade has seen an alarming increase in the number of pathogens that are resistant to antimicrobial drugs, in the hospital as well as in the community.(1) Among the gram-positive pathogens, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus species are the biggest threats. The situation is even more alarming with respect to gram-negative pathogens, especially because there are currently no late clinical trials involving new anti-infective drugs that are active against these pathogens.
that legalization of recreational marijuana is associated with increased traffic fatality rates. Applying these results to national driving statistics, nationwide legalization would be associated with 6800 (95% CI, 4200-9700) excess roadway deaths each year. Despite certain methodological differences, we found an increase similar to that reported by Aydelotte et al. 4 They reported an increase of 1.8 fatal crashes (equivalent to 2.0 fatalities) per BVMT. We concur with their opinion that changes may not be detected immediately after legalization but only after a longer time period or after commercial sales begin.We chose a control group consisting of all states with neither legal recreational nor medical marijuana to isolate the effects of marijuana. We did not require that control states have baseline attributes similar to the experimental states because the difference-in-difference technique removes biases in comparisons between experimental and control groups that result from permanent differences between those groups. Our conclusions, nonetheless, are limited by adjusting for only 3 state-specific factors that may have changed during the study period. It is possible that another confounder, rather than marijuana legalization and commercialization, caused the observed increase in roadway deaths.
With the volume of published ID-related research growing each year, both ID specialists and nonspecialists are challenged to stay current with the literature. Key ID-related publications in 2012 included updated recommendations on management of diabetic foot infections, articles on promising approaches to prevention and early treatment of HIV disease, and reports on developments in research on pharmacotherapies for methicillin-resistant Staphylococcus aureus bacteremia and Klebsiella pneumoniae infections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
