International consensus recommendations for the use of prolonged-infusion beta-lactam antibiotics: Endorsed by the American College of Clinical Pharmacy, British Society for Antimicrobial Chemotherapy, Cystic Fibrosis Foundation, European Society of Clinical Microbiology and Infectious Diseases, Infectious Diseases Society of America, Society of Critical Care Medicine, and Society of Infectious Diseases Pharmacists: An executive summary.

Intravenous ß-lactam antibiotics remain a cornerstone in the management of bacterial infections due to their broad spectrum of activity and excellent tolerability. ß-lactams are well established to display time-dependent bactericidal activity, where reductions in bacterial burden are directly associated with the time that free drug concentrations remain above the minimum inhibitory concentration (MIC) of the pathogen during the dosing interval. In an effort to take advantage of these bactericidal characteristics, prolonged (extended and continuous) infusions (PI) can be applied during the administration of intravenous ß-lactams to increase time above the MIC. PI dosing regimens have been implemented worldwide, but implementation is inconsistent. We report consensus therapeutic recommendations for the use of ß-lactam PI developed by an expert international panel with representation from clinical pharmacy and medicine. This consensus guideline provides recommendations regarding pharmacokinetic and pharmacodynamic targets, therapeutic drug monitoring considerations, and the use of PI ß-lactam therapy in the following patient populations: severely ill and nonseverely ill adult patients, pediatric patients, and obese patients. These recommendations provide the first consensus guidance for the use of ß-lactam therapy administered as PIs and have been reviewed and endorsed by the American College of Clinical Pharmacy (ACCP), the British Society for Antimicrobial Chemotherapy (BSAC), the Cystic Fibrosis Foundation (CFF), the European Society of Clinical Microbiology and Infectious Diseases (ESCMID), the Infectious Diseases Society of America (IDSA), the Society of Critical Care Medicine (SCCM), and the Society of Infectious Diseases Pharmacists (SIDP).

The effect of the COVID-19 pandemic on the prescribing of opioid and opioid use disorder medications within an academic medical center in California.

Introduction: The COVID-19 pandemic impacted healthcare operations affecting many patients with chronic pain and substance use disorder. Our study aimed to evaluate the effects of the COVID-19 pandemic on opioid and opioid use disorder (OUD) medication prescribing practices within a large academic health system in southern California. Methods: This retrospective cohort study included patients who received a prescription for chronic opioids or therapy for OUD between November 1, 2019 and September 1, 2020. The date range was divided into five specific time periods during the pandemic: November through December 2019 (pre-COVID and reference period), January through February 2020 (early COVID), March through April 2020 (policy/guidance change period), May through June 2020 (early post-guidance period), and July through August 2020 (late post-guidance period). The primary outcome was change in morphine milligram equivalents (MME) prescribed. Secondary outcomes included encounter type, mode of prescription ordering, naloxone prescriptions, and urine drug screen obtainment. Results: The cohort included 100 patients divided among the designated time periods. Seventy-percent of patients received opioids for chronic non-malignant pain and 10% received therapy for OUD. Although there were numerical increases in MMEs prescribed, no significant changes were seen in the MMEs prescribed at any timepoint relative to the pre-COVID timeframe despite reduced in-person visits, increased video and telephone encounters and increased electronic prescription utilization. Subgroup analyses of those with chronic pain only or OUD had similar findings. Conclusion: It appears that, generally, prescribing practices were sustained despite the various phases of the pandemic including transitions to and from telemedicine.

Early skills laboratory warnings: Laboratory faculty perspectives on student barriers for progression to experiential education.

INTRODUCTION: This study characterized faculty perceptions of student barriers to achieving an Entrustable Professional Activities (EPA) level 2 or higher in the Patient Care Provider domain. METHODS: Pharmacy skills laboratory faculty participated in a nominal group technique (NGT) session. Participants reflected on two questions: "What behaviors would result in a student not achieving a rank of EPA readiness level 2 or higher?" and "What knowledge and skills would result in a student not achieving a rank of EPA readiness level 2 or higher?" Participants developed a ranked list using silent brainstorming, idea generation, clarification, and discussion. RESULTS: Two NGT sessions were conducted. Group 1 reported (lack of) professionalism, (inability to perform) physical skills, (lack of) critical thinking and interpreting data gathered during physical skills, and (inability to achieve) programmatic outcomes and mile makers exams as barriers. Group 2 ranked behaviors as lack of independence, not taking roles and responsibilities seriously, inability to follow instructions, lack of classroom engagement, and disorganized and unable to prioritize. Group 2 ranked knowledge and skills of significant errors when making medication recommendations, inability to identify accurate medication history, inability to perform tasks with time constraints, poor patient communication, and inability to identify resources. CONCLUSIONS: Pharmacy skills laboratory faculty can identify behaviors, knowledge, or skills that may prevent a student from achieving an EPA readiness level 2 or higher such as lack of professionalism and poor critical thinking skills and should be empowered to identify early warning signs for students' success and progression to experiential education.

Characteristics of Successful International Pharmacy Partnerships.

Recommendations for global pharmacy collaborations are predominately derived from US institutions. This study utilized semi-structured interviews of global collaborators to assess important partnership components. Interviewees stated personal connections and understanding of each other's programs/systems were key components. Additionally, collaborators indicate that mutual benefits between partners can exist without the requirement for bidirectional exchange of learning experiences, and request and value partners and learners who are culturally aware, global citizens. This structured interview approach provided key insight into how to develop mutually beneficial, sustainable partnerships and provides additional confirmation that the five pillars of global engagement align with an international audience.

Critical Analysis of Apixaban Dose Adjustment Criteria.

Apixaban is indicated for the prevention of ischemic stroke in non-valvular atrial fibrillation (NVAF), as well as for the prevention and treatment of venous thromboembolism (VTE). Dose adjustment is based on age, weight, and serum creatinine in NVAF, while there are no recommended adjustment criteria for VTE. Such adjustment is unconventional compared to other commonly used medications. The objective of this manuscript is to critically analyze each apixaban dosing adjustment criterion and its associated outcomes. PubMed articles from March 2013 to March 2020 were selected with search terms "apixaban," and "dose adjustment," "adjustment," or "adjustment criteria." Pharmacokinetic studies demonstrated increased apixaban exposure in patients >65 years of age, those with extreme body weights, and those with advanced renal impairment, though post-hemodialysis dosing may off-set the elevated apixaban exposure. However, clinical data show that among patients >75 years, <60 kg, and with estimated glomerular filtration rate <50 mL/min, including those on dialysis, there is no reduction in apixaban safety or efficacy. Published literature describes variable dosing strategies utilized in clinical practice. Overall, apixaban dose adjustment criteria may need to be re-evaluated.

Evaluation of Home Medication Reconciliation by Clinical Pharmacists for Adult and Pediatric Cystic Fibrosis Patients.

Medication reconciliation is an important aspect of a patient's care process that is ideally performed by clinical pharmacists. Despite literature supporting this process in other patient populations, cystic fibrosis (CF) lacks research in this area. To address this, we designed a retrospective, multi-centered, non-controlled, cross-sectional study at four CF Foundation-accredited centers in the United States to evaluate the medication reconciliation process for adult and pediatric CF patients by documenting the number of home medications reconciled by clinical pharmacists and the number of patients with home medications that did not align with the current CF guidelines published in 2013. There were 105 adult patients and 72 pediatric patients included in the study analysis with a mean number of medications reconciled by clinical pharmacists of 17.4 (standard deviation (SD) 6.7) for adults and 13 (SD 4.6) for pediatric patients. The mean number of discrepancies from guidelines per patient was 1.61 (SD 1.2) for adult patients and 0.63 (SD 0.9) for pediatric patients. Pharmacists play an essential role in identifying and managing medication interactions and further research is necessary to investigate pharmacist impact on medication reconciliation.

Pharmacokinetics of Continuous Infusion Beta-lactams in the Treatment of Acute Pulmonary Exacerbations in Adult Patients With Cystic Fibrosis.

BACKGROUND: Several clinical trials have shown the efficacy of continuous infusion beta-lactam (BL) antibiotics in patients with cystic fibrosis (CF); however, little is known about pharmacokinetic changes during the treatment of an acute pulmonary exacerbation (APE). Identifying and understanding these changes may assist in optimizing antibiotic dosing during APE treatment. METHODS: This study was a retrospective cohort study of 162 adult patients with CF admitted to the University of Utah Hospital between January 1, 2008, and May 15, 2014, for treatment of an APE with both a continuous infusion BL and IV tobramycin. We extracted the administered doses of continuous infusion BLs and tobramycin along with serum drug concentrations and calculated medication clearance rates. The primary outcome was change in clearance rates of continuous infusion BLs between day 2 and day 7 of APE treatment. RESULTS: The BL clearance rate increased 20.7% (95% CI, 11.42 to 32.49; P < .001), whereas the tobramycin clearance rate decreased 6.3% (95% CI, -12.29 to -4.45; P < .001). The mean percent predicted FEV1 increased between admission and discharge by 12.2% (95% CI, -13.81 to -10.55; P < .001). CONCLUSIONS: Clinicians should monitor BL levels along with aminoglycoside levels and make dose adjustments to maximize the chance of optimal antibiotic treatment. Continuous infusion BL and tobramycin clearance can change dramatically during the treatment of an APE, which may necessitate significant changes in dosing to achieve optimal antibiotic levels. Clearance rates of these antibiotics may change in opposite directions, requiring specific monitoring of each medication.

Continuous infusion vs intermittent vancomycin in neurosurgical intensive care unit patients.

PURPOSE: Target plasma level achievement has remained a challenge in neurosurgical intensive care unit patients receiving intravenous vancomycin. We evaluated continuous infusion (CI) and intermittent vancomycin dosing strategies in these patients. METHODS: This retrospective cohort compared CI vancomycin (target random levels, 20-30 mg/L) to intermittent vancomycin (target troughs, 15-20 mg/L) in regards to achievement of target plasma levels, nephrotoxicity, pharmacodynamic target attainment, and cost savings in 130 patients. RESULTS: Continuous infusion resulted in greater achievement of goal plasma concentrations at the first steady-state level (40 vs 21.5%, P = .02), more rapid achievement of goal plasma concentrations (2.04 vs 3.76 days, P < .0001), and increased time within therapeutic range (55% vs 34%, P < .0001) but no significant difference in nephrotoxicity (15.4% vs 21.5%, P = .5). Continuous infusion improved pharmacodynamic target attainment (92.3% vs 30.8%, P < .0001) and also reduced levels drawn (3.8 vs 5.7, P = .0007), dose adjustments (1.4 vs 2.4, P = .0006), days of therapy (10.4 vs 14.1, P = .01), and mean total daily dose requirements (33 vs 35.7 mg/kg, P < .0001) per patient. CONCLUSIONS: Continuous infusion appears beneficial for improving attainment of target plasma concentrations, pharmacodynamic goals, and financial burden, without increasing risk of acute kidney injury.
