Clinical studies comparing vancomycin with alternative therapy for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia are limited. The objective of this study was to compare outcomes of early daptomycin versus vancomycin treatment for MRSA bacteremia with high vancomycin MICs in a geographically diverse multicenter evaluation. This nationwide, retrospective, multicenter (N = 11), matched, cohort study compared outcomes of early daptomycin with vancomycin for MRSA bloodstream infection (BSI) with vancomycin MICs 1.5 to 2 µg/mL. Matching variables, based on propensity regression analysis, included age, intensive care unit (ICU), and type of BSI. Outcomes were as follows: (1) composite failure (60-day all-cause mortality, 7-day clinical or microbiologic failure, 30-day BSI relapse, or end-of-treatment failure (EOT; discontinue/change daptomycin or vancomycin because of treatment failure or adverse event]); (2) nephrotoxicity; and (2) day 4 BSI clearance. A total of 170 patients were included. The median (interquartile range) age was 60 years (50–74); the median (range) Acute Physiology and Chronic Health Evaluation II score was 15 (10–18); 31% were in an ICU; and 92% had an infectious disease consultation. BSI types included endocarditis/endovascular (39%), extravascular (55%), and central catheter (6%). The median daptomycin dose was 6 mg/kg, and the vancomycin trough level was 17 mg/L. Overall composite failure was 35% (59 of 170): 15% due to 60-day all-cause mortality, 14% for lack of clinical or microbiologic response by 7 days, and 17% due to failure at end of therapy (discontinue/change because of treatment failure or adverse event). Predictors of composite failure according to multivariate analysis were age >60 years (odds ratio, 3.7; P < 0.01) and ICU stay (odds ratio, 2.64; P = 0.03). Notable differences between treatment groups were seen with: (1) end of therapy failure rates (11% vs 24% for daptomycin vs vancomycin; P = 0.025); (2) acute kidney injury rates (9% vs 23% for daptomycin vs vancomycin; P = 0.043); and (3) day 4 bacteremia clearance rates for immunocompromised patients (n = 26) (94% vs 56% for daptomycin vs vancomycin; P = 0.035). Results from this multicenter study provide, for the first time, a geographically diverse evaluation of daptomycin versus vancomycin for patients with vancomycin-susceptible MRSA bacteremia with vancomycin MIC values >1 µg/mL. Although the overall composite failure rates did not differ between the vancomycin and daptomycin groups when intensively matched according to risks for failure, the rates of acute kidney injury were significantly lower in the daptomycin group. These findings suggest that daptomycin is a useful therapy for clinicians treating patients who have MRSA bacteremia. Prospective, randomized trials should be conducted to better assess the potential significance of elevated vancomycin MIC.

Virtual TBL is an online adaptation of the team-based learning (TBL) instructional strategy, emphasizing collaborative learning and problem-solving. The emergency shift to virtual TBL during the COVID-19 pandemic presented unique challenges. This study aims to 1) compare overall pharmacy students' perceptions and attitudes toward face-to-face (FTF) TBL vs. virtual TBL in the didactic curriculum and stratify their perceptions and attitudes by various students' characteristics; 2) evaluate students' perceptions of the strengths and weaknesses of virtual TBL. This mixed-methods, pre-post, cross-sectional study utilized an anonymous survey to collect the data. Pharmacy students completed a survey to compare their perceptions and attitudes toward learning, class experience, learning outcomes achieved, and satisfaction with FTF TBL vs. virtual TBL using a 5-point Likert-type scale. Additionally, the survey included two open-ended questions to gather students' perceptions of the strengths and weaknesses of virtual TBL. Quantitative survey data were analyzed using the Wilcoxon matched-pairs signed rank exact test, while qualitative survey data were analyzed using thematic analysis. A total of 117 students (response rate of 59.4%) completed the study survey. Pharmacy students perceived FTF TBL to be superior to virtual TBL in their attitudes toward learning, class experience, learning outcomes achieved, and overall satisfaction across various students' characteristics. While the students identified some unique strengths of using virtual TBL, they also highlighted several weaknesses of using this learning modality compared to FTF TBL. Pharmacy students perceived FTF TBL to be superior to virtual TBL across various students' characteristics. These findings can be helpful to pharmacy programs considering the implementation of virtual TBL in their didactic curricula. Future research should explore whether a purposefully designed virtual TBL environment, as opposed to the pandemic-driven emergency TBL planning, can influence students' perceptions and attitudes toward virtual TBL.

Telavancin is a bactericidal lipoglycopeptide antibiotic that is structurally related to vancomycin. It demonstrates in vitro activity against a variety of Gram-positive pathogens including, but not limited to, methicillin-resistant Staphylococcus aureus (MRSA). Telavancin is currently FDA-approved for the treatment of complicated skin and skin-structure infections. Recently, two randomized clinical trials demonstrated the efficacy and safety of telavancin compared to vancomycin for the treatment of nosocomial pneumonia. Overall, telavancin has a favorable safety profile. However, mild gastrointestinal disturbances and reversible increases in serum creatinine were observed in clinical studies. Additional clinical studies are needed to evaluate telavancin's efficacy and safety in comparison to other antistaphylococcal agents for the treatment of infections such as bacteremia and endocarditis.

Background: Food and Drug Administration–approved daptomycin dosing uses actual body weight, despite limited dosing information for obese patients. Studies report alterations in daptomycin pharmacokinetics and creatine phosphokinase elevations associated with higher weight-based doses required for obese patients. Limited information regarding clinical outcomes with alternative daptomycin dosing strategies in obesity exists. Objective: This study evaluates equivalency of clinical and safety outcomes in obese patients with daptomycin dosed on adjusted body weight versus a historical cohort using actual body weight. Methods: This retrospective, single center study compared equivalency of outcomes with two one-sided tests in patients with body mass index ⩾30 kg/m2 who received daptomycin dosed on actual body weight versus adjusted body weight. The primary outcome was clinical failure. Secondary outcomes included 90-day readmission and 90-day mortality. A combined safety endpoint included creatine phosphokinase elevation, patient-reported myopathy, and rhabdomyolysis. Results: A total of 667 patients were screened for inclusion; 101 patients were analyzed with 50 in the actual body weight cohort and 51 in the adjusted body weight cohort. The two regimens were statistically equivalent for clinical failure (2% actual body weight versus 4% adjusted body weight; p < 0.001 for equivalency). The two regimens were also statistically equivalent for 90-day mortality (6% actual body weight versus 4% adjusted body weight; p = 0.0014 for equivalency). Limitations include single center, retrospective design, and sample size. Daptomycin dosing intensified throughout the study period. Conclusion: The two daptomycin dosing cohorts were statistically equivalent for both clinical failure and 90-day mortality. More data are needed to assess outcomes with higher (⩾8 mg/kg/day) daptomycin doses in this patient population.

Owing to the morbidity and mortality associated with invasive fungal infections, particularly in the immunocompromised host, development of new agents for both prevention and treatment is essential. Posaconazole is a recently approved extended-spectrum triazole available as an oral suspension. It exhibits fungistatic activity against a variety of fungal pathogens. Pharmacokinetic data in special patient populations (such as neutropenic patients with acute myelogenous leukemia or myelodysplastic syndrome, allogeneic hematopoietic stem cell transplant recipients, febrile neutropenic patients and pediatric patients) have been published recently. Controlled clinical trials establish posaconazole's safety and efficacy in infections, such as oropharyngeal candidiasis and prophylaxis against invasive fungal infections. Data are also emerging in the treatment of zygomycosis and selected cases of aspergillosis. Posaconazole is well tolerated during short- and long-term use, with the most commonly reported adverse events being mild-to-moderate gastrointestinal disturbances. Data suggest a relationship between posaconazole plasma concentrations and prophylactic efficacy; however, the role of therapeutic drug monitoring has yet to be completely defined. Since posaconazole is available only as an oral formulation, its use may be limited in critically ill patient populations.

To describe the development, implementation, and assessment of an internal medicine introductory pharmacy practice experience (IPPE) that was integrated with an existing advanced pharmacy practice experience (APPE) in internal medicine. A structured IPPE was designed for first-, second-, and third-year pharmacy (P1, P2, and P3) students. Activities for the IPPE were based on the established APPE and the individual learner's educational level. Students reported a greater understanding of clinical pharmacists’ roles, increased confidence in their clinical skills, and better preparation for APPEs. Peers viewed the approach as innovative and transferable to other practice settings. Participating faculty members provided a greater number of contact hours compared to traditional one-time site visits. Integrating an IPPE with an existing APPE is an effective and efficient way to provide patient care experiences for students in the P1-P3 years in accordance with accreditation standards.
