RESUMO
OBJECTIVE: To determine whether the gender of clinicians making antimicrobial stewardship recommendations has an impact on intervention acceptance rate. DESIGN: A retrospective, multivariable analysis of antimicrobial stewardship prospective audit and feedback outcomes. SETTING: A multisite healthcare system including Mayo Clinic Rochester (MN), Mayo Clinic Arizona, Mayo Clinic Florida and 17 health-system hospital sites, where prospective audit and feedback is performed and documented within an electronic tool embedded in the medical record. PARTICIPANTS: The study included 143 Mayo Clinic clinicians (84 cisfemales and 59 cismales). METHODS: Outcomes were analyzed from July 1, 2017, to June 30, 2022, for intervention rates, communication methods, and intervention acceptance by clinician gender, profession, patient age, and intensive care unit (ICU) status of patient. RESULTS: Of 81,927 rules, 71,729 rules met study inclusion. There were 18,175 (25%) rules associated with an intervention. Most of the rules were reviewed by pharmacists (86.2%) and stewardship staff (85.5%). Of 10,363 interventions with an outcome documented, 8,829 (85.2%) were accepted and 1,534 (14.8%) were rejected. Female clinicians had 6,782 (86.5%) of 7,843 interventions accepted, and male clinicians had 2,047 (81.2%) of 2,520 interventions accepted (P = .19). Female patients had more interventions than male patients (female vs male: 25.9% vs 24.9%; OR, 1.04; 95% CI, 1.02-1.08; P = .001). Patients in the ICU had a significantly lower intervention acceptance rate (ICU vs non-ICU: 78.2% vs 86.7%; OR, 0.56; 95% CI, 0.45-0.7; P < .001). CONCLUSIONS: Female and male clinicians were equally effective at prospective audit and feedback in a multisite antimicrobial stewardship program. Patients in the ICU were less likely to have stewardship interventions accepted.

PURPOSE: Surgical patients with a penicillin allergy label (PAL) are less likely to receive ß-lactams for surgical site infection (SSI) prophylaxis and more likely to receive second-line antibiotics, which may increase the risk of SSI, drug toxicities, and associated costs. We assessed the impact of implementing a pharmacist-led quality improvement project to increase the use of cefazolin as a first-line agent in this population. SUMMARY: After implementation of a pilot project in December 2021, all patients with a PAL and orders for preoperative antibiotics were risk stratified into high- or low-risk categories by a pharmacist. For the low-risk group, cefazolin was recommended. For the high-risk group, cefazolin was avoided and a second-line agent was administered. Our analysis compared 422 preintervention patients (August 15 to November 15, 2021) to 492 postintervention patients (December 15 to March 15, 2022). During the postintervention period, ß-lactam usage increased (from 12.6% to 37.8%, P < 0.001), while usage of vancomycin (45.5% vs 29.5%, P < 0.001) and other second-line antibiotics (87.4% vs 62.2%, P < 0.001) declined. There were no adverse reactions reported in the preintervention cohort, with 2 potential adverse reactions reported after the intervention (0% vs 0.4%, P = 0.190). Medication costs based on claims data were 50% to 80% lower for patients receiving cefazolin. CONCLUSION: In our cohort, a pharmacy-led antibiotic selection algorithm for patients with a PAL receiving perioperative antimicrobial prophylaxis resulted in increased use of ß-lactam antibiotics, decreased use of second-line antibiotics, and decreased costs without a significant change in the incidence of adverse reactions.

Objective: Methicillin-resistant Staphylococcus aureus (MRSA) infection is highly unlikely when nasal-swab results are negative. We evaluated the impact of an electronic prompt regarding MRSA nasal screening on the length of vancomycin therapy for respiratory indications. Design: Retrospective, single-center cohort study. Setting: Tertiary-care academic medical center (Mayo Clinic) in Jacksonville, Florida. Patients: Eligible patients received empiric treatment with vancomycin for suspected or confirmed respiratory infections from January through April 2019 (preimplementation cohort) and from October 2019 through January 2020 (postimplementation cohort). Intervention: The electronic health system software was modified to provide a best-practice advisory (BPA) prompt to the pharmacist upon order verification of vancomycin for patients with suspected or confirmed respiratory indications. Pharmacists were prompted to order a MRSA nasal swab if it was not already ordered by the provider. Methods: We reviewed patient records to determine the time from vancomycin prescription to de-escalation. The secondary end point was incidence of acute kidney injury. Results: The study included 120 patients (preimplementation, n = 61; postimplementation, n = 59). Median time to de-escalation was significantly shorter for the postimplementation cohort: 76 hours (interquartile range [IQR], 52-109) versus 42 hours (IQR, 37-61; P = .002). Acute kidney injury occurred in 11 patients (18%) in the preimplementation cohort and in 3 patients (5%) in the postimplementation cohort (P = .01; number needed to treat, 8). Conclusions: Implementation of a BPA notification for MRSA nasal screening helped decrease the time to de-escalation of vancomycin.
RESUMO
Acute pulmonary exacerbations are complications of cystic fibrosis (CF) and are associated with increased morbidity and mortality. Methicillin-resistant Staphylococcus aureus (MRSA) and Aspergillus fumigatus are organisms that have been detected in the lungs of CF patients. The focus of this review is to provide an overview of the classes of antimicrobials used for MRSA and allergic bronchopulmonary aspergillosis (ABPA), a hypersensitivity reaction caused by A. fumigatus. The current anti-MRSA antibiotics and medications for ABPA dosing recommendations are discussed. This article also reviews the findings from the MRSA utilization surveys and the pharmacokinetic and pharmacodynamic differences between CF and non-CF patients. Antimethicillin S. aureus antibiotics include ceftaroline, clindamycin, fluoroquinolone derivatives (ciprofloxacin, levofloxacin), glycopeptide derivatives (telavancin, vancomycin), linezolid, rifampin, sulfamethoxazole/trimethoprim, and tetracycline derivatives (doxycycline, minocycline, tigecycline). Medications used for ABPA include corticosteroids, amphotericin B, azole antifungals (isavuconazole, itraconazole, posaconazole, voriconazole), and a monoclonal antibody, omalizumab.

This review is the second article in the State-of-the-Art series and aims to evaluate medications used in the treatment of allergic bronchopulmonary aspergillosis (ABPA) in pediatric and adult patients with cystic fibrosis (CF). ABPA is one of several organisms that are found in the airways of CF patients. This review provides an evidence-based summary of pharmacokinetic (PK)/pharmacodynamic (PD), tolerability, and efficacy studies of medications including corticosteroids, amphotericin B, azole antifungals (isavuconazole, itraconazole, posaconazole, and voriconazole), and a monoclonal antibody omalizumab in the treatment of ABPA and identifies areas where further study is warranted.

Acute pulmonary exacerbations (APE) are a complication of cystic fibrosis (CF) and are associated with morbidity and mortality. Methicillin-resistant Staphylococcus aureus (MRSA) is one of many organisms that has been detected in the airways of patients with CF. This review provides an evidence-based summary of pharmacokinetic/pharmacodynamic (PK/PD), tolerability, and efficacy studies utilizing anti-MRSA antibiotics (ie, ceftaroline, clindamycin, fluoroquinolone derivatives (ciprofloxacin, levofloxacin), glycopeptide derivatives (telavancin, vancomycin), linezolid, rifampin, sulfamethoxazole/trimethoprim (SMZ/TMP), and tetracycline derivatives (doxycycline, minocycline, tigecycline) in the treatment of APE and identifies areas where further study is warranted. A recent utilization study of antimicrobials for anti-MRSA has shown some CF Foundation accredited care centers and affiliate programs are using doses higher than the FDA-approved doses. Further studies are needed to determine the PK/PD properties in CF patients with clindamycin, minocycline, rifampin, SMZ/TMP, telavancin, and tigecycline; as well as, efficacy and tolerability studies with ciprofloxacin, clindamycin, doxycycline, levofloxacin, minocycline, rifampin, SMZ/TMP, in CF patients with MRSA.

OBJECTIVES: The purpose of this study was to characterize the utilization of antibiotics for chronic methicillin-resistant Staphylococcus aureus (MRSA) infection in cystic fibrosis (CF) patients with acute pulmonary exacerbations (PEx). METHODS: An anonymous national cross-sectional survey of CF Foundation accredited care programs was performed using an electronic survey tool. RESULTS: Fifty-eight percent (152/261) CF Foundation accredited programs completed the survey. Ninety-eight percent (149/152) of respondents reported using antibiotics (oral or intravenous) against MRSA. Variability exists in the use of antibiotics amongst the programs and in the dosages utilized. For oral outpatient treatment, sulfamethoxazole/trimethoprim was the most commonly utilized antibiotic by both pediatric (109/287, 38%) and adult (99/295, 34%) respondents, of which, ten percent of reported to use it in combination with rifampin. For inpatient treatment, linezolid (both intravenous (IV) and oral) was most commonly utilized in both pediatric (IV 35/224, 16%; oral 41/224, 18%), and adult (IV 44/235, 19%; oral 38/235, 16%) respondents for inpatient treatment. IV vancomycin was the second most commonly utilized antibiotic by pediatric (70/224, 31%) and adult (71/235, 30%) respondents. Most respondents reported dose titration to achieve a vancomycin trough level of 15-20 mg/L (150/179, 84%). Topical or inhaled antibiotic utilization was reported to be an uncommon practice with approximately 70% of pediatric and adult respondents reporting to use them either rarely or never. The concomitant use of anti-MRSA and anti-pseudomonal antibiotics was common with 96% of pediatric and 99% of adult respondents answering in the affirmative. CONCLUSION: We conclude that anti-MRSA antibiotics are utilized via various dosage regimens by a majority of CF Foundation accredited care programs for the treatment of chronic MRSA in PEx, and there is no consensus on the best treatment approach.
