Purpose: The purpose of this study was to evaluate rates of delirium or coma-free days between continuous infusion sedative-dose ketamine and continuous infusion benzodiazepines in critically ill patients. Materials and Methods: In this single-center, retrospective cohort adult patients were screened for inclusion if they received continuous infusions of either sedative-dose ketamine or benzodiazepines (lorazepam or midazolam) for at least 24 h, were mechanically ventilated for at least 48 h and admitted to the intensive care unit of a large quaternary academic center between 5/5/2018 and 12/1/2021. Results: A total of 165 patients were included with 64 patients in the ketamine group and 101 patients in the benzodiazepine group (lorazepam n = 35, midazolam n = 78). The primary outcome of median (IQR) delirium or coma-free days within the first 28 days of hospitalization was 1.2 (0.0, 3.7) for ketamine and 1.8 (0.7, 4.6) for benzodiazepines (p = 0.13). Patients in the ketamine arm spent a significantly lower proportion of time with RASS −3 to +4, received significantly higher doses and longer durations of propofol and fentanyl infusions, and had a significantly longer intensive care unit length of stay. Conclusions: The use of sedative-dose ketamine had no difference in delirium or coma-free days compared to benzodiazepines.

AbstractProfessional standards for academic health care system pharmacy departments and clinical pharmacists advocate for research and scholarly activities. Developing and sustaining a research program in a clinical pharmacy department is challenging. Over the span of a decade, a robust pharmacy research program was developed in an academic medical center not affiliated with a college of pharmacy. The aim of this manuscript is to provide a framework suitable for scaling research in pharmacy departments within an academic medical center. Objectives to accomplish the aim includes describing the structure and evolution of the clinical pharmacy department research program, listing measurable outputs and achievements of the pharmacists and the program and describing the barriers encountered and solutions that were enacted to overcome them. Elements critical to building and sustaining a research program in the pharmacy department included long‐term commitment from within the department, a departmental research infrastructure, support from institutional leadership, research funding from the institution, and a growth mindset in accordance with company initiatives to support evolving research needs. A research curriculum was developed for pharmacy residents and pharmacists, created electronic tools for research proposal scientific reviews and allocation of funds, and established departmental research career development awards that allowed for protected time to pursue research and professional development. Over the first 10 years of the program, publication rates grew more than three‐fold, faculty appointments and promotions increased approximately five‐fold, and pharmacist investigators obtained extramural federal funding. Further offsetting clinical workload relative to dedicated research time remains a challenge. The experience and success at this academic medical center suggest it is feasible to develop a robust, sustainable clinical pharmacy department research program.

Abstract Purpose To describe the use of mechanical circulatory support in the setting of cardiac arrest and summarize pharmacists’ role in extracorporeal cardiopulmonary resuscitation (ECPR). Summary ECPR is increasingly used to reduce morbidity and improve mortality after cardiac arrest. ECPR employs venoarterial ECMO, which provides full circulatory perfusion and gas exchange in both adult and pediatric patients in cardiac arrest. After the emergency medicine team identifies potential candidates for ECPR, the ECMO team is consulted. If deemed a candidate for ECPR by the ECMO team, the patient is cannulated during ongoing standard cardiopulmonary resuscitation. A multidisciplinary team of physicians, nurses, perfusionists, pharmacists, and support staff is needed for successful ECPR. Pharmacists play a vital role in advanced cardiac life support (ACLS) prior to cannulation. Pharmacists intervene to make pharmacotherapy recommendations during ACLS, prepare medications, and administer medications as allowed by institutional and state regulations. Pharmacists also provide pharmacotherapy support in the selection of anticoagulation agents, ongoing vasopressor administration during ECMO cannulation, and the optimization of medication selection in the peri-ECPR period. Conclusion With the growing use of ECPR, pharmacists should be aware of their role in medication optimization during ECPR.

AbstractBackgroundNimodipine improves outcomes following aneurysmal subarachnoid hemorrhage (aSAH) and current guidelines suggest that patients with aSAH receive nimodipine for 21 days. Patients with no difficulty swallowing will swallow the whole capsules or tablets; otherwise, nimodipine liquid must be drawn from capsules, tablets need to be crushed, or the commercially available liquid product be used to facilitate administration through an enteral feeding tube (FT). It is not clear whether these techniques are equivalent. The goal of the study was to determine if different nimodipine formulations and administration techniques were associated with the safety and effectiveness of nimodipine in aSAH.MethodsThis was a retrospective multicenter observational cohort study conducted in 21 hospitals across North America. Patients admitted with aSAH and received nimodipine by FT for ≥3 days were included. Patient demographics, disease severity, nimodipine administration, and study outcomes were collected. Safety end points included the prevalence of diarrhea and nimodipine dose reduction or discontinuation secondary to blood pressure reduction. Predictors of the study outcomes were analyzed using regression modeling.ResultsA total of 727 patients were included. Administration of nimodipine liquid product was independently associated with higher prevalence of diarrhea compared to other administration techniques/formulations (Odds ratio [OR] 2.28, 95% confidence interval [CI] 1.41–3.67, p‐value = 0.001, OR 2.76, 95% CI 1.37–5.55, p‐value = 0.005, for old and new commercially available formulations, respectively). Bedside withdrawal of liquid from nimodipine capsules prior to administration was significantly associated with higher prevalence of nimodipine dose reduction or discontinuation secondary to hypotension (OR 2.82, 95% CI 1.57–5.06, p‐value = 0.001). Tablet crushing and bedside withdrawal of liquid from capsules prior to administration were associated with increased odds of delayed cerebral ischemia (OR 6.66, 95% CI 3.48–12.74, p‐value <0.0001 and OR 3.92, 95% CI 2.05–7.52, p‐value <0.0001, respectively).ConclusionsOur findings suggest that enteral nimodipine formulations and administration techniques might not be equivalent. This could be attributed to excipient differences, inconsistency and inaccuracy in medication administration, and altered nimodipine bioavailability. Further studies are needed.
