Multicenter Comparison of the Safety and Efficacy of Clopidogrel Versus Ticagrelor for Neuroendovascular Stents.

BACKGROUND: Dual antiplatelet therapy (DAPT) is commonly employed for neuroendovascular stenting due to the significant risk of thromboembolism. Clopidogrel and aspirin are most often selected as initial DAPTs; however, there is limited literature available to support guidance of DAPT in this setting. The objective of this study was to evaluate safety and efficacy in patients whose final regimen included either DAPT with aspirin and clopidogrel (DAPT-C) or DAPT with aspirin and ticagrelor (DAPT-T). METHODS: This was a multicenter, retrospective cohort of patients who underwent neuroendovascular stenting and received DAPT between July 1, 2017, and October 31, 2020. Study participants were allocated into groups based on discharge DAPT regimen. The primary outcome was incidence of stent thrombosis at 3-6 months on DAPT-C versus DAPT-T, as defined by the presence of thrombus on imaging or new onset stroke. Secondary outcomes included major and minor bleeding and death within 3-6 months after the procedure. RESULTS: Five hundred and seventy patients were screened across 12 sites. Of those, 486 were included (DAPT-C n = 360, DAPT-T n = 126). There was no difference in the primary outcome of stent thrombosis between the DAPT-C and DAPT-T groups (8% vs. 8%, p = 0.97) and no difference in any of the secondary safety outcomes. CONCLUSIONS: Using DAPT-C or DAPT-T regimens in a broad population of neuroendovascular stenting procedures appears to have similar safety and efficacy profiles. Further prospective evaluation is warranted to streamline the practice of DAPT selection and monitoring to determine the impact on clinical outcomes.

Comparing Medication History Capture Rates In-Person Versus Hybrid: A Multisite Pilot Study.

Purpose: Medication history is the method many organizations use to adhere to The Joint Commission's (TJC) National Patient Safety Goal (NPSG) to communicate accurate patient medication information. Literature is sparse comparing the number of medication histories completed in-person versus virtually. Methods: This is a single system, multi-site, retrospective observational study. Patients included were admitted through the Emergency Department during October 2022. The primary aim of this study compared the percent capture rates of medication history between 2 hybrid sites to an in-person site within a health-system. Our secondary objective compared the differences in the 'medication history acuity score' (MHAS), defined as the total number of edits, additions, and deletions made during a medication history. Results: The medication history capture rate at the in-person site was 74% and at the hybrid sites were 91% and 80%. There were no differences in total medications on each medication history between in-person and hybrid (11 [5-16] vs 11 [6-16]; P = .252). There were no differences in changes made on medication histories between in-person and hybrid (4 [1-7] vs 3 [1-7]; P = .595). Conclusions: Our study demonstrates that medication history capture rates and MHAS are comparable in both in-person and hybrid environments. This similarity suggests the feasibility of implementing hybrid models for medication history services in diverse healthcare settings, potentially enhancing the capacity of health systems to meet TJC NPSG. These findings indicate that hybrid models could be an effective strategy for healthcare systems to optimize their medication history services, especially in settings with varied patient volumes and site specialties.

Review of Target-Specific Anticoagulation Reversal Agents.

Bleeding related to direct oral anticoagulants accounts for nearly half of emergency department visits annually and until recently there were no reversal antidotes available. As there continues to be a shift in prescribing practices away from warfarin, it is essential to have these reversal agents readily available for the treatment of life-threatening bleeds associated with these anticoagulants. In addition, for agents that continue to lack a targeted reversal agent (eg, low-molecular-weight heparin, antiplatelets, and new antithrombotics), it is imperative that research continues to evaluate improved reversal strategies. This review focuses on target-specific anticoagulation reversal agents currently available in the United States (protamine, idarucizumab, and andexanet alfa) and summarizes agents that are in the pipeline for these anticoagulants and antiplatelets.

Safety and Efficacy of Urea for Hyponatremia.

Background and Objective: Urea is an alternative for treatment of hyponatremia however, its use has not been widely studied. The purpose of this study was to evaluate the safety and efficacy of urea for the treatment of hyponatremia. Methods: A retrospective cohort of patients with hyponatremia (serum sodium <135 mEq/L) of any cause who received at least 1 dose of urea during hospitalization and no prior use of urea. Serum sodium levels were collected at baseline and for 4 days or until urea was discontinued, whichever occurred first. The primary outcome was the serum sodium change between baseline and discharge or urea discontinuation. Results: Median serum sodium increased 2 [IQR, 0-4] mEq/L per day after urea administration at a median dose of 30 g/day. A significant difference in serum sodium was observed between baseline and discharge or discontinuation (124.2 ± 4 vs 130.1 ± 5.1; P < .001) and serum blood urea nitrogen (BUN) levels (18.4 ± 13.1 vs 41.1 ± 26.6; P ≤ .001). Serum sodium overcorrection (increase >8 mEq/L in 24 hours) occurred in 6 patients (8%). Urea was discontinued in 39 patients (53%); 20 discontinuations were due to patient intolerance. Conclusion: Urea appears to be an effective treatment for hyponatremia; however, patient tolerance, the rate of serum sodium overcorrection, and outpatient affordability may limit its use.

Management of tandem occlusions in patients who receive rtPA.

BACKGROUND: Tandem occlusions exist in 17-32% of large vessel occlusion (LVO) strokes. A significant concern is bleeding when carotid stenting is performed in tandem with thrombectomy due the administration of antiplatelet agents such as glycoprotein IIb/IIIa inhibitors (GP2b3aI) after receiving rtPA, but data are limited in this setting. METHODS: A mutlicenter, retrospective chart review was conducted at two comprehensive stroke centers to assess the safety and efficacy of using GP2b3aI to facilitate carotid stent placement simultaneously with endovascular thrombectomy in patients who have received rtPA. RESULTS: Overall, 32 patients were included in this study, with average age of 66.3 ± 10.4 years and predominantly male (87.5%). The cause of stroke was mostly large artery atherosclerosis (59.4%) and the thrombectomy target vessels were typically first- or second segment middle cerebral artery (37.5% and 31.3%). Time from symptom onset to rtPA bolus was 1.8 h [interquartile range (IQR) 1.5-2.7], rtPA bolus to first pass was 2 h [IQR 1.5-3.1], rtPA bolus to GP2b3aI bolus was 2 h [IQR 1.6-3.5], and rtPA bolus to aspirin and clopidogrel administration was 4.3 h [IQR 2.6-8.9] and 6.6 h [IQR 4.5-11.6] respectively. No patients had acute in-stent thrombosis or post-op bleeding from the access site. Two patients (6.3%) had significant hemorrhagic conversion. CONCLUSION: The use of GP2b3aI in the setting of tandem occlusions that required emergent stent placement post-rtPA appears safe and effective. Given the small sample size, these findings should be interpreted cautiously, and need to be confirmed in a larger patient population.

Facilitators and Barriers to Nursing Implementation of Continuous Glucose Monitoring (CGM) in Critically Ill Patients With COVID-19.

OBJECTIVE: We describe our implementation of a continuous glucose monitoring (CGM) guideline to support intravenous insulin administration and reduce point of care (POC) glucose monitoring frequency in the coronavirus disease 2019 medical intensive care unit (MICU) and evaluate nurses' experience with implementation of CGM and hybrid POC + CGM protocol using the Promoting Action on Research in Health Services framework. METHODS: A multidisciplinary team created a guideline providing criteria for establishing initial sensor-meter agreement within each individual patient followed by hybrid use of CGM and POC. POC measures were obtained hourly during initial validation, then every 6 hours. We conducted a focus group among MICU nurses to evaluate initial implementation efforts with content areas focused on initial assessment of evidence, context, and facilitation to identify barriers and facilitators. The focus group was analyzed using a qualitative descriptive approach. RESULTS: The protocol was integrated through a rapid cycle review process and ultimately disseminated nationally. The Diabetes Consult Service performed device set-up and nurses received just-in-time training. The majority of barriers centered on contextual factors, including limitations of the physical environment, complex device set-up, hospital firewalls, need for training, and CGM documentation. Nurses' perceived device accuracy and utility were exceptionally high. Solutions were devised to maximize facilitation and sustainability for nurses while maintaining patient safety. CONCLUSION: Outpatient CGM systems can be implemented in the MICU using a hybrid protocol implementation science approach. These efforts hold tremendous potential to reduce healthcare worker exposure while maintaining glucose control during the COVID-19 pandemic.

Pharmacy-Based Nursing Education Utilizing a Social Media Platform.

Social media has changed the way individuals communicate and recently multiple articles have been published highlighting the utilization of social media for education. To our knowledge, cross-discipline education utilizing these platforms has not been evaluated. The purpose of this study was to implement a pharmacist-led, social media-based nursing education program and evaluate the perceived value. A curriculum of pharmacy-related issues was developed and topics were posted to the neurocritical care unit (NCCU) Facebook group or emailed to non-Facebook users weekly. A pre- and posteducation survey was sent out evaluating the program's effectiveness. Thirty-seven nurses were members of the NCCU Facebook group and 33 received the education via email. A total of 29% and 19% of nurses completed the pre- and posteducation survey, respectively. Of those who completed the survey, 36% received education via Facebook. As compared with the preeducation survey, there were no statistically significant differences in nursing performance on fact-based questions (P value > .05 on all assessment questions); however, 100% of respondents wanted to continue this education delivery. Utilizing social media as a means of cross-discipline education was well-received; however, the solitary utilization should be used cautiously, as performance did not improve on assessment questions.

Pharmacologic Management of Cerebral Vasospasm in Aneurysmal Subarachnoid Hemorrhage.

Aneurysmal subarachnoid hemorrhage (aSAH) is responsible for 5% to 10% of all strokes in the United States annually and is a neurologic emergency with considerable morbidity and mortality. A common complication of aSAH is cerebral vasospasm (CVS) or narrowing of the cerebral arteries. While nearly 70% of aSAH patients will develop CVS, approximately 30% of those patients will go on to develop delayed cerebral ischemia, defined as symptomatic vasospasm or cerebral infarction demonstrated on imaging. While the pathophysiology of CVS is unclear, the prevention and treatment of this complication are a focus of ongoing research. Despite continued efforts, only one medication, nimodipine, is Food and Drug Administration approved for the improvement of neurologic outcomes by reducing the incidence and severity of ischemic deficits in patients with CVS during aSAH. This review provides nurse practitioners and the bedside nursing staff with a summary of the available literature on the pharmacologic management of CVS. It focuses on oral, intravenous, intra-arterial, and intraventricular medications available in the United States that may be utilized in the management of CVS.

Adjusted versus actual body weight dosing of 4-factor prothrombin complex concentrate in obese patients with warfarin-associated major bleeding.

The package insert of 4-factor prothrombin complex concentrate (4F-PCC) contains specific dosing recommendations stating to determine the patients dose based on their INR and weight, capping the weight at 100 kg. However, the mean body mass index (BMI) in the 4F-PCC U.S. approval study was 27 kg/m2, and there is a lack of literature identifying the ideal dosing strategy in obesity. We conducted a retrospective analysis of obese patients (BMI ≥ 30 kg/m2) who received 4F-PCC for warfarin associated emergent bleeding reversal. Treatment groups were those that received 4F-PCC on adjusted body weight (AdjBW) and those on actual body weight (ActBW). The primary outcome was the percent of patients achieving coagulopathy reversal, defined as a post-treatment INR < 1.4 for neurologic indications and < 1.5 for all others. A total of 78 obese patients were included (28 AdjBW and 50 ActBW). Baseline INR (3.1 vs. 2.8; p = 0.052) and BMI (33.6 vs. 33.6 kg/m2) were similar between groups. Achievement of goal INR was significantly lower in the AdjBW group (36% vs. 68%; p = 0.006). A majority of patients had intracranial hemorrhage (32% vs. 54%; p = 0.06), and the median dose of 4F-PCC was lower in the AdjBW group (2120 vs. 2500 units; p = 0.02). Dosing 4F-PCC using adjusted body weight in obese patients resulted in a significantly lower rate of coagulopathy reversal. ActBW should be used to dose 4F-PCC in obese patients when the 100 kg dose cap is utilized per the package insert recommendations.

Acute Management of Hypertension Following Intracerebral Hemorrhage.

Intracerebral hemorrhage (ICH) is responsible for approximately 15% of strokes annually in the United States, with nearly 1 in 3 of these patients dying without ever leaving the hospital. Because this disproportionate mortality risk has been stagnant for nearly 3 decades, a main area of research has been focused on the optimal strategies to reduce mortality and improve functional outcomes. The acute hypertensive response following ICH has been shown to facilitate ICH expansion and is a strong predictor of mortality. Rapidly reducing blood pressure was once thought to induce cerebral ischemia, though has been found to be safe in certain patient populations. Clinicians must work quickly to determine whether specific patient populations may benefit from acute lowering of systolic blood pressure (SBP) following ICH. This review provides nurses with a summary of the available literature on blood pressure control following ICH. It focuses on intravenous and oral antihypertensive medications available in the United States that may be utilized to acutely lower SBP, as well as medications outside of the antihypertensive class used during the acute setting that may reduce SBP.

Management of Chronic Hypertension Following Intracerebral Hemorrhage.

Acute blood pressure control after a cerebrovascular event is integral in the immediate care of these patients to preserve perfusion to ischemic areas and prevent intracerebral bleeding. The majority of patients with ischemic stroke or intracerebral hemorrhage (ICH) present with preexisting hypertension and therefore require a treatment plan after the acute phase. The presence of chronic hypertension after ICH has often been discussed as a modifiable risk factor for recurrent events. Clinical evidence is relatively lacking for clinicians to understand the extent of blood pressure lowering and the optimal agents to use in this setting. Limited data exist describing the long-term management of hypertension in patients after cerebrovascular events. This review provides nurses with a summary of the available literature on long-term blood pressure management to minimize the risk of secondary ICH and ischemic stroke. It focuses on oral antihypertensive medications available in the United States that may be utilized to manage chronic hypertension immediately after the postacute phase of care to lower blood pressure and to improve long-term outcomes.

Oral factor Xa inhibitors for the treatment of left ventricular thrombus: a case series.

Left ventricular thrombus (LVT) formation usually necessitates short term anticoagulation for thrombus resolution and to prevent embolic events. Historically, vitamin K antagonist therapy has been the treatment of choice. However, with the advent of direct acting anticoagulants, their role in the management of LVT is not clear. Patients were included if they had received rivaroxaban or apixaban for more than 1 day for LVT documented on imaging. The primary objective was resolution of LVT at 3 months based on assessment by an independent cardiologist review of initial and subsequent imaging results. The principle safety objective was to assess major or clinically relevant non-major bleeding using GUSTO, TIMI, and BARC bleeding criteria. During the 2-year study period seven patients were treated with rivaroxaban and three with apixaban. Two patients who had received apixaban and one on rivaroxaban were lost to follow up. In those with an initial and follow-up ECHO (n = 6) the median time to follow up imaging was 214 (IQR 33-414) days and complete LVT resolution was observed in 83% of patients. One patient on rivaroxaban had a bleeding events that was minimal (TIMI), Type 2 (BARC), or classified as mild (GUSTO) due to pulmonary hemorrhage. In those deemed not to be a candidate for vitamin K antagonist the use of rivaroxaban or apixaban may be a considered in the treatment of LVT. Further research in this area is needed to assess the efficacy and safety of using FXAI for treatment of LVT.

Review of Continuous Infusion Neuromuscular Blocking Agents in the Adult Intensive Care Unit.

The use of continuous infusion neuromuscular blocking agents remains controversial. The clinical benefit of these medications may be overshadowed by concerns of propagating intensive care unit-acquired weakness, which may prolong mechanical ventilation and impair the inability to assess neurologic function or pain. Despite these risks, the use of neuromuscular blocking agents in the intensive care unit is indicated in numerous clinical situations. Understanding pharmacologic nuances and clinical roles of these agents will aid in facilitating safe use in a variety of acute disease processes. This article provides clinicians with information regarding pharmacologic differences, indication for use, adverse effects, recommended doses, ancillary care, and monitoring among agents used for continuous neuromuscular blockade.

3-Factor Versus 4-Factor Prothrombin Complex Concentrate for Warfarin Reversal in Severe Bleeding: A Multicenter, Retrospective, Propensity-Matched Pilot Study.

Current guidelines recommend 4-factor prothrombin complex concentrate (4PCC) for emergent reversal of bleeding secondary to warfarin. While current research has demonstrated superiority of 4PCC over plasma, direct comparisons with 3-factor PCC (3PCC) are lacking. The purpose of this study is to compare the efficacy and safety of 3PCC and 4PCC. We conducted a retrospective analysis of patients who received PCC at one of four medical centers. All patients in the 3PCC group were treated at one center that utilizes a fixed, weight-based dosing protocol. After evaluation of all patients meeting inclusion criteria, propensity-score matching was used to adjust for differences in treatment characteristics. There was no difference in the primary outcome of INR ≤ 1.4 between 3PCC and 4PCC in both the unmatched (85.7 vs. 90.6 %; p = 0.37) and matched (84.2 vs. 92.1 %; p = 0.48) analyses. There was a significant difference in goal INR achieved favoring 4PCC (56.3 vs 90.0 %; p < 0.02) when baseline INR > 4.0. A total of three thrombotic events were documented, all in the 4PCC group. We found no difference in the rate of INR reversal in those treated with 3PCC and 4PCC. However, those with a baseline INR > 4.0 may experience more successful INR reversal with 4PCC.

The role of hormone replacement therapy in the intensive care management of deceased organ donors: a primer for nurses.

Donation after brain death remains the primary contributor to the supply of organs available for transplantation in the United States. After brain death, both a surge of catecholamines and a dysregulation of the neurohormonal axis may result in hypotension, decreased organ perfusion, and reduced viability of organs to be transplanted. Hormone replacement therapy is widely used to maintain organ perfusion and has been shown to increase the number of organs procured. This article reviews the literature and mechanisms supporting the use of hormone replacement therapy in brain-dead organ donors and provides clinicians with information regarding the administration, monitoring, and preparation of thyroid hormone, arginine vasopressin, and corticosteroids.

Clinical Advanced Pharmacy Practice Experience Rotations During COVID-19: Evaluation of a Transition to Virtual Learning.

BackgroundAll Advanced Pharmacy Practice Experience (APPE) pharmacy rotations at a large academic medical center were converted to virtual experiences during the beginning of the coronavirus disease 2019 (COVID-19) pandemic. Objective: This study aimed to describe information obtained through pre- and post-rotation surveys, implemented to improve experiences for future students who may be required to complete virtual APPE pharmacy rotations. Methods: A single-center, descriptive study was conducted at a 1382-bed academic medical center. A pre- and post-rotation survey was sent to 32 students, and a post-rotation survey was sent to 38 preceptors via email to assess newly implemented virtual rotations. Results: Students' response rate for pre- and post-rotation surveys was 59% and 41%, respectively, and the preceptors' response rate for the post-rotation survey was 37%. A statistically significant improvement in videoconferencing abilities after the rotation was found for students but no differences in other skills were noted. In the post-rotation survey, students rated all of the following areas as being "effective": rotation as a whole, virtual topic and patient discussions; but were "neutral" regarding the utility of the introductory training guide. In the post-rotation survey, preceptors rated all of the following areas as being "effective": rotation as a whole, virtual topic and patient discussions. Conclusion: Abrupt shifts to virtual pharmacy clinical rotations due to COVID-19 have led to many challenges. Both students and preceptors felt that virtual rotations were an effective alternative to in-person experiences; however, further studies are warranted to evaluate actual performance compared to perceived effectiveness.

Retrospective evaluation of dexmedetomidine dosing in a cohort of neurologically injured obese critically ill patients.

Background: Dexmedetomidine is used in neurocritical care units (NCCUs) due to the light, dose-dependent sedation, and anxiolysis provided. It is unknown how to dose dexmedetomidine in obese patients. The primary objective is to assess the ability to achieve the goal Richmond Agitation Sedation Scale (RASS) measurements in obese patients with a neurological injury who are solely on dexmedetomidine before and after an institutional dosing change from actual body weight (ABW) to adjusted body weight (AdjBW). Methods: This study included patients admitted to the NCCU with a neurological condition, required dexmedetomidine for at least 8 h as a sole sedative, and weighed ≥120% of ideal body weight. Percentage of RASS measurements within the goal range (-1 to +1) during the first 48 h while on dexmedetomidine were compared between patients dosed on ABW and on AdjBW. Results: Sixty-eight patients in the ABW cohort and 72 patients in the AdjBW cohort were included. There were no statistical differences between the two groups (ABW vs. AdjBW) in the percent of RASS measurements in the goal range (53.2% ± 34.8% vs. 55% ± 37%; P = 0.78), mean weight (99.2 ± 26 vs. 96.8 ± 20.9 kg; P = 0.55), or the average dose of dexmedetomidine required to achieve first goal RASS score (0.4 ± 0.3 vs. 0.4 ± 0.3 mcg/kg/h; P = 0.98). Conclusions: Dosing dexmedetomidine using AdjBW in obese critically ill neurologically injured patients for ongoing sedation resulted in no statistical difference in the percent of RASS measurements within the goal when compared to ABW dosing. Further studies are warranted.

Evaluation of Dexmedetomidine Dosing in Obese Critically Ill Patients.

BACKGROUND: Dexmedetomidine is a highly selective α2-adrenoreceptor agonist that produces dose-dependent sedation, anxiolysis, and analgesia without respiratory depression. Due to these ideal sedative properties, there has been increased interest in utilizing dexmedetomidine as a first-line sedative for critically ill patients requiring light sedation. OBJECTIVE: To evaluate the ability to achieve goal intensive care unit (ICU) sedation before and after an institutional change of dosing from actual (ABW) to adjusted (AdjBW) body weight in obese patients on dexmedetomidine. METHODS: This study included patients ≥ 18 years old, admitted to a surgical or medical ICU, required dexmedetomidine for at least 8 hours as a single continuous infusion sedative, and weighed ≥ 120% of ideal body weight. Percentage of RASS measurements within goal range (-1 to +1) during the first 48 hours after initiation of dexmedetomidine as the sole sedative agent or until discontinuation dosed on ABW compared to AdjBW was evaluated. RESULTS: 100 patients were included in the ABW cohort and 100 in the AdjBW cohort. The median dosing weight was significantly higher in the ABW group (95.9 [78.9-119.5] vs 82.2 [72.1-89.8] kg; p = 0.001). There was no statistical difference in percent of RASS measurements in goal range (61.5% vs 69.6%, p = 0.267) in patients that received dexmedetomidine dosed based on ABW versus AdjBW. CONCLUSION: Dosing dexmedetomidine using AdjBW in obese critically ill patients for ongoing ICU sedation resulted in no statistical difference in the percent of RASS measurements within goal when compared to ABW dosing. Further studies are warranted.
