Pig movement and antimicrobial use drive transmission of livestock-associated staphylococcus aureus CC398.
Staphylococcus aureus was originally considered a hospital-associated organism, but new classes of methicillin-resistant strains have emerged outside of the hospital setting, including among livestock. This article discusses a recent study which examined the transportation of pigs on over 200 farms; the authors of this article contend that the results of the study demonstrate the importance of cooperation between occupational health services, genomics, veterinary medicine, and farmers in understanding the epidemiology of MRSAs as related to livestock.

Cost-effectiveness of pre-operative Staphylococcus aureus screening and decolonization.
In this study, the investigators developed a decision analytic model to evaluate the impact of a preoperative Staphylococcus aureus decolonization bundle on surgical site infections (SSIs), health-care-associated costs (HCACs), and deaths due to SSI. The investigators predict that the treat-all strategy would be the most effective and cost-saving strategy for preventing SSIs. However, they concluded that because this strategy might select more extensively for mupirocin-resistant S. aureus and cause more medication adverse effects than the test-and-treat approach or the SOC, additional studies are needed to define its comparative benefits and harms.

Randomized controlled trial of a self-administered five-day antiseptic bundle versus usual disinfectant soap showers for preoperative eradication of Staphylococcus aureus colonization.
The objective of this study was to determine the efficacy in eradicating Staphylococcus aureus (SA) carriage of a 5-day preoperative decolonization bundle compared to 2 disinfectant soap showers, with both regimens self-administered at home. The investigators concluded that an outpatient preoperative antiseptic decolonization bundle aimed at 4 body sites was significantly more effective in eradicating SA than the usual disinfectant showers (ie, the control).

Denominator matters in estimating antimicrobial use: a comparison of days present and patient days.
This study discussed how the choice of different denominator metrics may affect antimicrobial use rates. There is an approximately one-third higher difference if you use days present compared to using patient days. This difference was influenced by short length of stay.

Perioperative antibiotics for clean hand surgery: a national study.
This research is a national study on the use of prophylactic antibiotics in soft tissue hand surgery when antimicrobials are not indicated. Insurance claims from the Truven MarketScan Databases were used to identify patients who had 1 of 5 outpatient surgery procedures including: open or endoscopic carpal tunnel release; trigger finger release; de Ouervain release, and wrist ganglion excision between 2009 and 2015. An increase of 72.5% in prophylactic intravenous antibiotics was shown from 2009 to 2015. Patients with a younger age, male sex, lower income, or obesity had higher odds of receiving antibiotics. Total charge for these antibiotics equaled $1.6 million.
