ABSTRACT Clinical pharmacists are increasingly recognized as vital contributors to acute stroke care, yet their role remains inconsistently defined and underutilized across health care systems. This consensus statement explores the expanding presence of clinical pharmacists within interdisciplinary stroke teams, particularly in the management of both acute ischemic stroke ( AIS ) and hemorrhagic stroke. This consensus statement panel was composed of clinical pharmacists, emergency medicine physicians, and a vascular neurologist. The Grading of Recommendations, Assessment, Development, and Evaluation ( GRADE ) approach was used to assess the level of certainty and strength of recommendations. We focused on two questions regarding the clinical pharmacist's role in caring for adult patients presenting to the emergency department ( ED ) with AIS or hemorrhagic stroke. Despite the very low level of evidence, a consensus was reached for the following recommendations: (1) clinical pharmacist involvement in AIS care for adult patients presenting to the ED and (2) clinical pharmacist involvement in hemorrhagic stroke care for adult patients presenting to the ED . Based on the available literature, we believe optimizing the clinical pharmacist role is a critical factor in improving time‐sensitive treatment and equity in care delivery.

Abstract Introduction: Current guidelines state the effectiveness of desmopressin to reduce hematoma expansion in antiplatelet-related intracerebral hemorrhage (ICH) is uncertain. This study sought to determine if desmopressin decreased hematoma expansion in ICH patients on antiplatelet agents. Methods: We conducted a multi-center, retrospective propensity-matched cohort study at 11 US emergency departments (ED) that participate in EMPHARM-NET. Adult patients ≥18 years with a primary diagnosis of spontaneous ICH on antiplatelets prior to admission from January 1, 2017 through May 1, 2021 were included. The primary endpoint was good or excellent hemostatic efficacy within the first 24 hours following ICH between patients that did and did not receive desmopressin. Brain imaging was reviewed using 3D-Slicer by blinded expert physicians. Results: Overall, 1408 patients were evaluated for inclusion. A total of 324 patients were included, of which 13.8% (n=45) received desmopressin and 86.1% (n=279) did not. After propensity matching, 35 patients receive desmopressin compared to 140 controls. Baseline hematoma volume (27.6 mL vs. 2.1 mL) and was significantly higher in the desmopressin group. The primary endpoint of good or excellent hemostatic efficacy was similar between groups (74.3% desmopressin group vs. 85% control group, -10.7% [-28.1% to 6.7%]). There was no difference in secondary outcomes. Conclusion: In this multicenter cohort, patients receiving desmopressin had higher baseline intraparenchymal hematoma volume, and did not appear to result in improved hemostatic efficacy relative to the control group. These results suggest against routine administration of desmopressin for antiplatelet-related ICH, though future study in a randomized trial design is necessary.

Abstract Background Urinary tract infections (UTIs) are commonly treated in the emergency department (ED), and unfortunately, resistance to first-line agents is increasing. Objectives To characterize treatment of pyelonephritis in a nationally representative sample of ED patients and to identify patient- and treatment-specific factors associated with receiving initial inactive antibiotics. Methods We conducted a multicentre, observational cohort study utilizing the Emergency Medicine PHARMacotherapy Research NETwork (EMPHARM-NET), comprising 15 geographically diverse US EDs. All patients ≥18 years of age with a diagnosis of pyelonephritis between 2018 and 2020 were included. The primary endpoint was the proportion of patients who received initial inactive empirical antibiotic therapy and to identify predictive factors of inactive antibiotic therapy. Results Of the 3714 patients evaluated, 223 had culture-positive pyelonephritis. Median patient age was 50.1 years and patients were mostly female (78.3%). Overall, 40.4% of patients received an IV antibiotic, most commonly ceftriaxone (86.7%). The most frequently prescribed antibiotics were cefalexin (31.8%), ciprofloxacin (14.3%), cefdinir (13.5%) and trimethoprim/sulfamethoxazole (12.6%). Overall, 10.3% of patients received initial inactive therapy. After adjustment in a multivariable analysis, long-acting IV antibiotic was predictive of inactive therapy (OR 0.23, 95% CI 0.07–0.83). Conclusions In our prospective, multicentre observational study, we found that only 40.4% of patients with pyelonephritis received empirical IV antibiotics in the ED, contributing to inactive therapy. Receipt of long-acting IV antibiotics was independently associated with a decreased rate of initial inactive therapy. This reinforces guideline recommendations to administer long-acting IV antibiotics empirically in the ED upon suspicion of pyelonephritis.

AbstractBackgroundUropathogen resistance, fluoroquinolone‐resistance (FQR), and extended spectrum beta‐lactamase (ESBL), has been observed to be emerging worldwide with prevalences above recommended thresholds for routine empirical treatment. The primary aim of our study was to determine the prevalence of FQR from a geographically diverse sample of United States emergency departments (EDs).MethodsWe conducted a multi‐center, observational cohort study using a network of 15 geographically diverse US EDs. All patients ≥18 years of age with the primary or secondary diagnosis of urinary tract infection (UTI) in the ED identified using International Classification of Diseases (ICD‐10) diagnosis code of cystitis, pyelonephritis, or UTI from 2018 to 2020 were included. We calculated descriptive statistics for uropathogens and susceptibilities. Logistic regression analysis was used to identify antimicrobial resistance risk factors associated with FQR Escherichia coli.ResultsAmong 3779 patients who met inclusion criteria, median age was 62.9 years (interquartile range [IQR]: 41–77.6) and 76.3% were female. The most common diagnoses were complicated (41.2%) and uncomplicated cystitis (40.3%). E. coli was the most common pathogen (63.2%), followed by Klebsiella pneumoniae (13.2%) and Enterococcus species (5.8%). Across all sites, overall E. coli FQ‐resistance prevalence was 22.1%, ranging from 10.5 to 29.7% by site. The prevalence of ESBL‐producing uropathogen was 7.4%, ranging from 3.6% to 11.6% by site. Previous IV or oral antimicrobial use in the past 90‐days and history of a multi‐drug resistant pathogen were associated with FQ‐resistant E. coli (odds ratio [OR] 2.68, 95% confidence interval [CI]: 2.04–3.51, and OR 6.93, 95% CI: 4.95–9.70, respectively). Of the patients who had FQ‐resistant E. coli or an ESBL‐producing uropathogen isolated, 116 (37.1%) and 61 (36.7%) did not have any documented risk factors for resistance.ConclusionFQ‐resistant E. coli is widely prevalent across US sites highlighting the need for ongoing monitoring of antimicrobial resistance and, at some locations, modification of empirical treatments.
