1252 • CID 2019:68 (1 April) • CORRESPONDENCECosts associated with MRSA nares screens may be offset by the avoidance of unnecessary empiric anti-MRSA therapy, associated therapeutic mon-itoring, and potential adverse effects. Multiple studies have demonstrated a decrease in anti-MRSA therapy, serum-level monitoring, and costs with using MRSA nares screens [4, 5]. In addition, many healthcare facilities already utilize MRSA screens for infection prevention and control measures. Such institutions can collaborate with their infection con-trol program and utilize MRSA nares screens for antimicrobial stewardship efforts, as well.While it has been suggested that risk factors may be the optimal choice to drive therapy decisions, we would argue the performance of predisposing risk factors and clinical prediction models or risk scores for MRSA fall short, compared to nasal screens, in their predictive per-formance, as demonstrated in multiple studies [6, 7]. This can be partly attrib-uted to both the relatively infrequent incidence of MRSA infection and the often non-specific nature of risk factors. Therefore, we believe nasal screens have strong and consistent clinical utility in the right prescribing setting.An aim of antimicrobial stewardship programs is to minimize the inappro-priate and unnecessary use of antibiotics and their associated adverse outcomes (ie, toxicities, resistance, and cost). Similar to incorporating any antimicro-bial stewardship tool, including other rapid diagnostic tests, institutions should evaluate the potential value from utiliz-ing MRSA nares screens for improving patient care.NotesPotential conflicts of interest.

A total of 200 cases (76 used prophylactic antibiotics and 124 did not) were included in their study, and they reported that the use of prophylactic antibiotics was of no benefit in aspiration pneumonia  (AP). AP means anaerobic pneumonia. For this reason, it is absolutely necessary to use anaerobic-spectrum antibiotics in AP. In their study, 35 cases in the antibiotic group received ceftriaxone monotherapy, but there is no anaerobic effect of ceftriax-one monotherapy. This amount is almost half that of the prophylaxis group (n = 35, 46%). Therefore, the antibiotic prophylaxis group of the study had to be evaluated in (76 − 35 = 41) 41 patients. Consequently, the results of the study should be inter-preted with caution. If all the patients in the prophylaxis group had received appro-priate antibiotics, the results could be very different. We think that the published results do not reflect a real-life situation.NotePotential conflicts of interest. Both authors: No reported conflicts.
