Rethinking residency recruitment, application, and interview processes to benefit applicants and programs long-term.

Pharmacy residency recruitment and interviews have been significantly impacted by the COVID-19 pandemic. Many traditional recruitment events and interviews were transitioned from in-person to virtual, and new approaches to recruitment, such as virtual open houses, were developed. There are limited data on how these changes impacted pharmacy residency applicants and programs, and the future of virtual events is currently unknown. We highlight recommendations for virtual recruitment and interviews and provide suggestions for residency programs and national organizations to improve virtual processes in the future.

A Continuing Education Activity Durably Addressed Knowledge Gaps Related to Penicillin Allergies Among Pharmacists and Pharmacy Technicians.

Background: Penicillin allergy is one of the most frequent self-reported allergies; however, only about 10% of reported allergies are accurate. Objectives: Through the creation of a continuing pharmacy education (CPE) activity, we sought to assess knowledge gaps and comfort levels in the management of penicillin allergies. Methods: A 1-hour enduring-content CPE activity was offered as an interactive course from September 20, 2019, to September 20, 2020. Participants completed 3 surveys (pre-survey, post-survey, and follow-up survey). Participants were pharmacists and pharmacy technicians who completed, at a minimum, the activity and both pre- and post-surveys. The primary outcome was the percentage of participants scoring >80% on knowledge-based questions on the post-survey compared with the pre-survey. Secondary outcomes included pre-post comparisons on knowledge-based questions, participants' self-report of an allergy, and comfort levels dispensing cephalosporins in a patient with a self-reported penicillin allergy. Results: A total of 389 participants completed the CPE activity, with 176 included for analysis. Significantly more participants scored >80% on knowledge-based questions on the post-survey compared with the pre-survey (71.6% vs 22.7%, P < .001). There was no significant difference between the percentage of participants scoring >80% on the post-survey and the follow-up survey (71.6% vs 65%, P = .119). The majority of participants (74%) felt comfortable dispensing a cephalosporin in a patient with a penicillin allergy on the pre-survey, with similar percentages on the post- and follow-up surveys (77% and 90%, respectively). Conclusion: A targeted continuing education program improved overall knowledge, which was sustained for up to 2 months.

Effect of Obesity on Clinical Outcomes of Patients Treated With Cefepime.

Background: As the prevalence of obesity climbs, dosing of antimicrobials, particularly cephalosporins, is becoming a greater challenge for clinicians. Data are lacking for appropriate dosing of cefepime, an anti-pseudomonal cephalosporin that is widely used as an empiric anti-pseudomonal agent. Objective: The purpose of this study was to determine the rate of clinical treatment failure in obese patients compared with nonobese patients receiving cefepime as definitive monotherapy. Methods: Adult inpatients treated with cefepime monotherapy for ≥72 hours were included. Patients were excluded if they (1) were not able to achieve culture clearance within 72 hours and (2) had polymicrobial infections requiring more than one antibiotic for definitive therapy. Results: Fifty-eight obese patients and 56 nonobese patients were included. Pseudomonas aeruginosa, Escherichia coli, and Enterobacter spp were the most prevalent organisms isolated. Most organisms had a minimum inhibitory concentration of ≤1 µg/mL to cefepime with no differences in minimum inhibitory concentration distributions between groups. Definitively, 60% of patients received cefepime 1 g, while almost 40% received cefepime 2 g. Clinical failure occurred in 52% of patients (67% obese vs 36% nonobese; P = .001), with study group (odds ratio = 1.057, 95% confidence interval = 1.008-1.109) and respiratory source (odds ratio = 3.251, 95% confidence interval = 1.378-7.667) being independent predictors of failure. There were no differences in hospital length of stay, all-cause mortality, or 30-day readmissions. Conclusions: Obese patients treated with cefepime are more likely to experience treatment failure than nonobese patients. Larger trials examining the reasons for clinical failure in obese patients treated with cefepime are needed to confirm the findings from this preliminary work.

Common Bacterial and Viral Infections: Review of Management in the Pregnant Patient.

OBJECTIVE: To review the treatment of common bacterial and viral infections occurring in the pregnant patient. DATA SOURCES: A literature search of MEDLINE was performed (inception to October 2018). The Centers for Disease Control and Prevention website was utilized for additional information. STUDY SELECTION AND DATA EXTRACTION: Relevant English-language studies and those conducted in humans were considered. DATA SYNTHESIS: ß-Lactams alone or in combination are the preferred treatment for many common infections in pregnancy, such as urinary tract infections, pelvic inflammatory disease (PID), gonococcal infections, syphilis, chancroid, upper- and lower-respiratory-tract infections, certain gastrointestinal infections, Group B Streptococcus, listeriosis, and intrauterine inflammation or infection. Macrolides, particularly azithromycin, are also utilized for the treatment of PID, chlamydia, gonococcal infections, chancroid, community-acquired pneumonia, and certain gastrointestinal infections. Other antibiotics or antivirals such as vancomycin, aminoglycosides, metronidazole, nitrofurantoin, fosfomycin, acyclovir, valacyclovir, and oseltamivir are included in the preferred therapy for some common bacterial and viral infections in pregnant patients as well. Relevance to Patient Care and Clinical Practice: This review synthesizes available evidence of treatments of common infections in pregnancy and provides a concise summary to guide clinicians on empirical treatment during pregnancy. CONCLUSIONS: There are limited data on clinical outcomes in pregnant patients with common bacterial and viral infections. Empirical management decisions require balance of benefit and risk to both mother and infant. Although few clinical practice guidelines have quality evidence for strong recommendations in this population, clinicians should weigh antimicrobial dosing, pharmacokinetics, safety, and established effectiveness to optimize antimicrobial therapy in pregnancy.

An Evaluation of Pharmacist-Led Interventions for Inpatient HIV-Related Medication Errors.

Background: Inpatient HIV-related medication errors occur in up to 86% of patients. Objective: To evaluate the number of antiretroviral therapy (ART)- and opportunistic infection (OI)-related medication errors following the implementation of pharmacist-directed interventions. Methods: This quasi-experiment assessed adult patients with HIV who received ART, OI prophylaxis, or both from December 1, 2014, to February 28, 2017 (pre-intervention) or December 1, 2017, to February 28, 2018 (post-intervention). Pre-intervention patients were assessed retrospectively; verbal and written education were provided (intervention); prospective audit and feedback was conducted for post-intervention patients. The primary outcome was rate of ART errors between groups. Secondary outcomes included rate of OI errors, time to resolution of ART and OI errors, types of errors, and rate of recommendation acceptance. Results: Sixty-seven patients were included in each group. ART errors occurred in 44.8% and 32.8% (P = .156), respectively. OI prophylaxis errors occurred in 11.9% versus 9% (P = .572), respectively. Medication omission decreased significantly in the post-intervention group (31.3% vs 11.9%; P = .006). Pharmacist-based interventions increased in the post-intervention group (6.3% vs 52.9%; P = .001). No statistical difference was found in time to error resolution (72 vs 48 hours; P = .123), but errors resolved during admission significantly increased (50% vs 86.8%; P < .001). No difference was found in rate of intervention acceptance (100% vs 97%). Conclusion and Relevance: ART and OI prophylaxis errors resolved a day faster in the pharmacist-led, post-intervention period, and there was a trend toward error reduction. Future interventions should target prescribing errors on admission using follow-up education and evaluation of medication reconciliation practices in HIV-infected patients.

Risk Factors for Failure in Complicated Intraabdominal Infections.

OBJECTIVES: Approximately 20% of patients with complicated intraabdominal infections (cIAIs) fail therapy. The purpose of this study was to identify risk factors for clinical failure in patients with cIAIs. METHODS: International Classification of Diseases, Ninth Revision codes for cIAIs were obtained to identify patients. Adult patients who received at least 48 hours of intravenous antibiotics were included. Patients were chronologically matched for age, sex, and comorbidities. The primary outcome was clinical failure. Statistical analysis included bivariate tests and multivariable logistic regression. RESULTS: A total of 1405 patients were screened; 139 patients were included. The median (interquartile range) age and Charlson Comorbidity Index were 54 (37-62) years and 0 (0-1), respectively. Clinical failure was observed in 47 patients (34%), with 5 deaths (3.6%). Multivariate analysis of the unmatched population showed older age was protective (odds ratio [OR] 0.967, 95% confidence interval [CI] 0.944-0.991). In the matched population elevated serum creatinine (OR 2.2168, 95% CI 1.091-4.308) and increased time to source control (OR 1.015, 95% CI 1.000-1.030) were predictive of clinical failure. CONCLUSIONS: In a low comorbid cIAI population with and without surgical intervention, serum creatinine was an independent risk factor for clinical failure. In the matched case-control of patients, time to source-control procedure was an independent predictor of clinical failure.

Membrane-Anchored Cyclic Peptides as Effectors of Mitochondrial Oxidative Phosphorylation.

The echinocandins are membrane-anchored, cyclic lipopeptides (CLPs) with antifungal activity due to their ability to inhibit a glucan synthase located in the plasma membrane of fungi such as Candida albicans. A hydrophobic tail of an echinocandin CLP inserts into a membrane, placing a six-amino acid cyclic peptide near the membrane surface. Because processes critical for the function of the electron transfer complexes of mitochondria, such as proton uptake and release, take place near the surface of the membrane, we have tested the ability of two echinocandin CLPs, caspofungin and micafungin, to affect the activity of electron transfer complexes in isolated mammalian mitochondria. Indeed, caspofungin and micafungin both inhibit whole chain electron transfer in isolated mitochondria at low micromolar concentrations. The effects of the CLPs are fully reversible, in some cases simply via the addition of bovine serum albumin to bind the CLPs via their hydrophobic tails. Each CLP affects more than one complex, but they still exhibit specificity of action. Only caspofungin inhibits complex I, and the CLP inhibits liver but not heart complex I. Both CLPs inhibit heart and liver complex III. Caspofungin inhibits complex IV activity, while, remarkably, micafungin stimulates complex IV activity nearly 3-fold. Using a variety of assays, we have developed initial hypotheses for the mechanisms by which caspofungin and micafungin alter the activities of complexes IV and III. The dication caspofungin partially inhibits cytochrome c binding at the low-affinity binding site of complex IV, while it also appears to inhibit the release of protons from the outer surface of the complex, similar to Zn(2+). Anionic micafungin appears to stimulate complex IV activity by enhancing the transfer of protons to the O2 reduction site. For complex III, we hypothesize that each CLP binds to the cytochrome b subunit and the Fe-S subunit to inhibit the required rotational movement of the latter.

Antifungal-Associated Drug-Induced Cardiac Disease.

The etiology of cardiomyopathies are classified into 4 main groupings (dilated, hypertrophic, restrictive, and idiopathic) and can be mechanistically caused by myocarditis, conduction abnormalities, focal direct injury, or nutritional deficiency. Based on our review of this topic, evidence suggests that echinocandin-related cardiac dysfunction is a mitochondrial drug-induced disease caused by focal direct myocyte injury. With caspofungin or anidulafungin administration into the heart via central line, exposure is likely extreme enough to induce the acute toxicity. Chronic or low-dose exposure may lead to hypertrophic cardiomyopathy; however, only acute exposures have been explored to date.

High-dose amphotericin: yay or nay? A case series and literature review.

Invasive fungal infections pose significant morbidity and mortality risks, particularly those caused by moulds. Available antifungal classes are limited by toxicities and are increasingly susceptible to resistance, particularly amongst challenging fungal pathogens. The purpose of this case series and literature review was to characterize the use of a high-dose lipid formulation of amphotericin B. A case series is presented including patients who received high-dose lipid formulation amphotericin B (≥7.5 mg/kg/day) between June 2012 and August 2021. Additionally, a systematic literature review was conducted by searching the PubMed database for English-language studies involving individuals who received high-dose amphotericin B therapy (≥7.5 mg/kg) using lipid formulations. Nine patients were included in the case series, receiving an average of 8.9 ± 1.3 mg/kg liposomal amphotericin B over a mean of 11.0 ± 10.8 days predominantly for mould infections including Mucorales, aspergillosis and Fusarium. The patients were primarily cared for in intensive care units, with varying treatment histories and outcomes. A total of 11 studies (n=260 patients) met inclusion criteria for the literature review. Responses to high-dose liposomal amphotericin B ranged from 8% to 100%, often showing favourable outcomes. High doses of liposomal amphotericin B were well tolerated both in the case series and in published literature, with serum creatinine changes being the most commonly reported adverse event. However, multi-patient studies continue to report less than favourable (range 8-62%) response rates. High-dose liposomal amphotericin B, either alone or in combination with other antifungal agents, might be a viable strategy for managing invasive fungal infections when few treatment choices exist.

Counting the Cost of Daptomycin Versus Vancomycin in Hospitalized Patients: A Cost Minimization Analysis.

Daptomycin use for gram-positive infections has increased. This cost minimization analysis aimed to determine cost and/or time savings of daptomycin over vancomycin. The estimated hospital cost savings was US$166.41 per patient, and pharmacist time saved of almost 20 minutes per patient. Daptomycin has the potential to save both time and money.

The Role of Consumerism in Pharmacy Education.

The notion of consumerism and that students are customers of pharmacy colleges was explored by proponents and opponents of the idea. First, a working definition of a "customer" in pharmacy education is pondered with respect to the roles and responsibilities of students and schools/colleges of pharmacy. Second, the pros and cons of "student-centered" education are considered in the light of students and their families being consumers of the educational experience. Third, the duality of student-centered education is discussed including student engagement/disengagement in their learning, professional/unprofessional behaviors, and shared/individual responsibilities. Lastly, learning and teaching environment dynamics are discerned when higher education becomes more student-centric and how that may affect the overall outcome of the student and the goals of pharmacy educational programs.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in 2022.

Keeping abreast of the antimicrobial stewardship-related articles published each year is challenging. The Southeastern Research Group Endeavor identified antimicrobial stewardship-related, peer-reviewed literature that detailed an actionable intervention during 2022. The top 13 publications were selected using a modified Delphi technique. These manuscripts were reviewed to highlight actionable interventions used by antimicrobial stewardship programs to capture potentially effective strategies for local implementation.

Antifungal resistance, combinations and pipeline: oh my!

Invasive fungal infections are a strong contributor to healthcare costs, morbidity and mortality, especially amongst hospitalized patients. Historically, Candida was responsible for approximately 15% of all nosocomial bloodstream infections. In the past 10 years, the epidemiology of Candida species has altered, with increasing prevalence of resistant species. With rising fungal resistance, especially in Candida spp., the demand for novel antifungal therapies has exponentially increased over the last decade. Newer antifungal agents have become an attractive option for patients needing long-term therapy for infections or those requiring antifungal prophylaxis. Despite advances in coverage of non-Candida pathogens with newer agents, clinical scenarios involving multidrug-resistant fungal pathogens continue to arise in practice. Combination antifungal therapy can lead to a host of side-effects, some of which can be drug limiting. Additional antifungal therapies with enhanced fungal spectrum of activity and decreased rates of adverse effects are warranted. Fosmanogepix, ibrexafungerp, olorofim and rezafungin may help fill some of these gaps in the antifungal armamentarium.

Penicillin-allergy delabelling resources for clinicians practicing in resource-limited settings: a full educational resource review of the grey literature.

Background: The clinical and financial consequences associated with a penicillin-allergy label are increasingly evident and have garnered support from international organizations to prioritize penicillin-allergy delabelling programmes. Most settings lack access to resources including drug allergy specialists and rely on general practitioners (GPs) and pharmacists. Objectives: The aim of this scoping review was to identify and describe freely available penicillin-allergy delabelling materials to guide clinicians practising in resource-limited settings with initiative application. Methods: This scoping review searched two grey literature databases, six targeted websites and consulted content experts to identify freely available materials in the English language that provided evidence-based and actionable penicillin-allergy delabelling strategies. Study investigators ranked and voted on which screened resources should be included in the final review. Characteristics of resources were evaluated and compared. Results: Out of 1191 total citations, 6 open-access resources were included. Penicillin-allergy toolkits featuring various delabelling strategies were identified in four resources. The toolkits supported a broad range of downloadable and adaptable materials, predominantly targeted towards GPs. Patient educational materials were also provided. Another resource highlighted a point-of-care penicillin-allergy risk assessment calculator via a free mobile app that quickly and accurately identified low-risk penicillin-allergic patients. The final resource, a supplemental instructional video, presented impactful and standardized delabelling strategies that clinicians can adopt into daily practices. Conclusions: Limited penicillin-allergy delabelling materials are available in the grey literature but existing resources provide broad and diverse opportunities. Additional support from health protection agencies is critical to augment ongoing delabelling efforts.

Evaluation of an Antifungal Stewardship Initiative Targeting Micafungin at an Academic Medical Center.

Delays in the treatment of proven invasive fungal disease have been shown to be harmful. However, empiric treatment for all patients at risk of infection has not demonstrated benefit. This study evaluates the effects of a micafungin stewardship initiative on the duration of therapy and clinical outcomes at the University of Mississippi Medical Center in Jackson, Mississippi. This single-center quasi-experiment evaluated patients who received micafungin. Adult inpatients who received at least one treatment dose of micafungin in the pre-intervention (1 October 2020 to 30 September 2021) or post-intervention (1 October 2021 to 30 April 2022) groups were included. Patients were placed on micafungin for prophylaxis and those who required definitive micafungin therapy were excluded. An algorithm was used to provide real-time recommendations in order to assess change in the treatment days of micafungin therapy. A total of 282 patients were included (141 pre-group versus 141 post-group). Over 80% of the patients included in the study were in an intensive care unit, and other baseline characteristics were similar. The median number of treatment days with micafungin was 4 [IQR 3-6] in the pre-group and 3 [IQR 2-6] in the post-group (p = 0.005). Other endpoints, such as time to discontinuation or de-escalation, hospital mortality, and hospital length of stay, were not significantly different between the groups. An antifungal stewardship initiative can be an effective way to decrease unnecessary empiric antifungal therapy for patients who are at risk of invasive fugal disease.

Artemether-lumefantrine: an option for malaria.

OBJECTIVE: To review the pharmacology, pharmacokinetics, safety, and efficacy of artemether-lumefantrine for the treatment of Plasmodium falciparum malaria. DATA SOURCES: English-language articles indexed in PubMed (1947-November 2011) were identified, using the search terms artemether-lumefantrine, artemether-lumefantrine AND malaria, Coartem, and Coartem AND malaria. STUDY SELECTION AND DATA EXTRACTION: Available English-language articles were reviewed. In addition, the malaria treatment regimens recommended by region as provided by the World Health Organization and the treatment guidelines from the Centers for Disease Control and Prevention were reviewed. DATA SYNTHESIS: Artemether-lumefantrine is an artemisinin-derived combination antimalarial approved by the Food and Drug Administration in 2009 for the treatment of P. falciparum malaria. The dual mechanisms of action of artemether-lumefantrine provide rapid and sustained parasite clearance. In the reviewed studies, the polymerase chain reaction (PCR)-corrected 28-day cure rates of artemether-lumefantrine were noninferior to the most common comparators, including chloroquine, dapsone, and other artemisinin derivatives (86-100% vs 51-100%, respectively). PCR-corrected day-42 cure rates were 92-99.3% for artemether-lumefantrine versus 62-100% for the comparator groups. The major adverse effects (gastrointestinal and central nervous system) were mild to moderate in severity and did not require a change in therapy. Although adherence to artemether-lumefantrine has been described as a potential problem due to the complicated dosing schedule, studies have described clinical cure rates similar to those of other antimalarials. CONCLUSIONS: Artemether-lumefantrine is a safe and effective treatment for children and adults with P. falciparum malaria.

Diabetic foot infections: A microbiologic review.

Diabetes mellitus continues to be an increasingly common comorbidity. Diabetic foot infections are one of the most common causes of hospitalization in this population, and account for a significant portion of increased hospitalization and healthcare expenditure. Complications, such as osteomyelitis, can necessitate the use of multiple, prolonged antibiotic courses. These courses often consist of broad-spectrum, empiric therapy determined by organisms considered to be commonly associated with these types of infections. Extended periods of broad-spectrum antibiotic regimens can contribute to antibiotic resistance and ultimately limit future treatment options. Furthermore, patient specific risk factors can impact the microbiologic diversity found in these infections. As a result, it is difficult to determine if a single empiric regimen is appropriate for all instances of diabetic foot infections. OBJECTIVES AND METHODS: This review analyzes global literature relating to the culture methods, incidence, risk factors, resistance patterns, and geographic distribution of the microorganisms isolated from diabetic foot infections using the PRISMA statement for systematic review and meta-analysis reporting. RESULTS: Staphylococcus aureus remains a significant pathogen, with a growing incidence of Pseudomonas aeruginosa and MDR gram-negative bacilli. CONCLUSIONS: Though some individualized risk factors can be useful, local epidemiology and resistance patterns remain essential for antibiotic treatment considerations.

Cryptococcosis in a patient with multiple myeloma receiving pomalidomide: a case report and literature review.

While overall survival with multiple myeloma (MM) has improved, patients suffer from overwhelming tumor burden, MM-associated comorbidities, and frequent relapses requiring administration of salvage therapies. As a result, this vicious cycle is often characterized by cumulative immunodeficiency stemming from a combination of disease- and treatment-related factors leading to neutropenia, T-cell deficiency, and hypogammaglobulinemia. Infectious etiologies differ based on the duration of MM and treatment-related factors, such as number of previous treatments and cumulative dose of corticosteroids. Herein, we present the case of a patient who was receiving pomalidomide without concomitant corticosteroids for MM and was later found to have cryptococcosis, as well as findings from a literature review. Most cases of cryptococcosis are reported in patients with late-stage MM, as well as those receiving novel anti-myeloma agents, such as pomalidomide, in combination with corticosteroids or following transplantation. However, it is likely cryptococcosis may be underdiagnosed in this population. Due to the cumulative immunodeficiency present in patients with MM, clinicians must be suspicious of cryptococcosis at any stage of MM.
