The aim of the study is to determine if ketamine infusions in combination with opioid therapy for the management of sickle cell disease (SCD) presenting with vaso-occlusive crisis (VOC) resulted in a length-of-stay difference compared to when ketamine was not utilized. This single center, retrospective, observational study performed at an academic medical center evaluated 12 adult patients with SCD-VOC who received a ketamine infusion with standard opioid therapy between 2014 and 2017. Patients were excluded if the primary diagnosis was not VOC or they did not survive to discharge.

Patients with breast cancer frequently experience financial hardship, often due to the high costs of anti-cancer drugs. We sought to develop alternative trastuzumab dosing strategies, compare their pharmacokinetic effectiveness to standard dosing, and assess the expected financial implications of transitioning to them. We extracted clinical data from the records of 135 retrospectively identified patients with HER2-positive early breast cancer at a single, urban comprehensive cancer center who were treated with trastuzumab between 2017 and 2019.

Article Synopsis
  • Pharmacogenomics is being explored to improve drug prescribing during surgeries and reduce adverse reactions, though its use in perioperative care is still limited.
  • The ImPreSS Trial, a study involving elective surgery patients, tested pharmacogenomic decision support for anesthesia providers, revealing that 58% accessed genomic results before or during procedures.
  • Results showed a mostly positive application of pharmacogenomics, with faculty more likely to use the information compared to less experienced staff, as well as a low incidence of issues related to genomic medicine during surgeries.

Introduction: Rituximab carries a boxed warning for severe or fatal infusion reactions; most occurring with the initial infusion. Prior studies established that if the initial rituximab infusion is tolerated, subsequent infusions can be given safely over 90 min. The University of Chicago Medicine (UCM) did not have a standardized method to document infusion reactions for outpatient chemotherapy patients, making it challenging for providers to know a patients' eligibility for rapid infusion.

Background: Venous thromboembolism (VTE) is a leading cause of maternal morbidity and mortality in the United States. Subcutanous unfractionated heparin (UFH) has been used for decades for VTE prophylaxis and under many obstetric quality of care initiatives, hospitalized antepartum patients now receive doses as high as 10,000 units every 12 hours. This practice increases the likelihood of UFH administration around the time that epidural labor analgesia is requested or neuraxial analgesia for cesarean delivery is needed.

Known disparities exist in the availability of pharmacogenomic information for minority populations, amplifying uncertainty around clinical utility for these groups. We conducted a multi-site inpatient pharmacogenomic implementation program among self-identified African-Americans (AA; = 135) with numerous rehospitalizations ( = 341) from 2017 to 2020 (NIH-funded ACCOuNT project/clinicaltrials.gov#NCT03225820).

Growing evidence suggests disparities in the prevalence, management, progression, and outcomes of chronic, nonmalignant pain-related conditions, especially for African American patients. The purpose of this review is to explore studied causative factors that influence the management of chronic pain among African Americans, including factors that result in disparate care that may contribute to unfavorable outcomes. This narrative review is based on available literature published on this topic published within the last 10 years.

Article Synopsis
  • A pharmacist-led initiative was implemented at an academic medical center to enhance the management of automated dispensing cabinet (ADC) medication overrides, improving compliance with medication policies.
  • The initiative involved revising the medication override list, updating policies, and streamlining workflows, which resulted in a significant increase in the number of medications available for override and a drastic reduction in dispense settings.
  • Post-implementation, the proportion of compliant override dispenses rose dramatically from 59% to 98%, while the overall ADC override rate decreased from 1.4% to 1.2%, indicating improved efficiency and safety in medication dispensing.

Objectives: Integration of pharmacogenomics into clinical care is being studied in multiple disciplines. We hypothesized that understanding attitudes and perceptions of anesthesiologists, critical care and pain medicine providers would uncover unique considerations for future implementation within perioperative care.

Methods: A survey (multiple choice and Likert-scale) was administered to providers within our Department of Anesthesia and Critical Care prior to initiation of a department-wide prospective pharmacogenomics implementation program.

Variable responses to medications complicates perioperative care. As a potential solution, we evaluated and synthesized pharmacogenomic evidence that may inform anesthesia and pain prescribing to identify clinically actionable drug/gene pairs. Clinical decision-support (CDS) summaries were developed and were evaluated using Appraisal of Guidelines for Research and Evaluation (AGREE) II.

Purpose: Intravenous immunoglobulin (IVIG) is used to replenish immunoglobulins in hypogammaglobulinemia (HG) caused by hematologic malignancies (HM) or their treatment (autologous stem-cell transplantation [ASCT] and chimeric antigen receptor T-cell therapy [CAR-T]), in an effort to reduce the risk of infections. However, there is limited evidence to support this use, and IVIG supplies are limited and shortages are common.

Methods: An IVIG stewardship program (ISP) was implemented with the following requirements for IVIG administration: immunoglobulin G (IgG) level < 400 mg/dL (corrected for paraprotein) for post-ASCT and post-CAR-T patients, or IgG < 400 mg/dL with a history of a bacterial infection within the preceding 3 months for those with HM.

Drug-drug interactions between digoxin and the triazole antifungal agents, mediated via various cytochrome P450 isozymes, have been described in the literature. Posaconazole is not extensively metabolized by these isozymes but is both a p-glycoprotein (P-gp) substrate and inhibitor. To our knowledge, there have been no published cases of clinically significant posaconazole-digoxin drug-drug interactions.
