Pilot Study on the Impact of Early Subcutaneous Basal Insulin Administration in Diabetic Ketoacidosis.

Purpose/Background: Recent studies have shown improved outcomes with the initiation of earlier subcutaneous (SQ) basal insulin. The purpose of this study was to examine the effects of early SQ basal insulin administration on hospital length of stay in patients with mild to moderate diabetic ketoacidosis (DKA). Methods: This was a retrospective, single-center study from a large community teaching hospital that included patients 18 years or older with mild to moderate DKA, identified using ICD-10 codes, who received intravenous (IV) insulin. Patients who received SQ basal insulin prior to a documented anion gap ≤12 mmol/L were considered to have received early SQ basal insulin and were compared to patients who received SQ basal insulin after closure of their anion gap (AG). The primary outcome was hospital length of stay. Secondary outcomes included intensive care unit length of stay, duration of IV insulin, time to anion gap closure, and incidences of rebound hyperglycemia. Safety outcomes included incidences of hypoglycemia, and hypokalemia. Results: Of 301 patients screened, 108 patients were included in the final analysis. Forty patients received early SQ basal insulin and 68 did not. Median hospital length of stay in the nonearly group was 71 h, compared to 62 h in the early group (P = .57). Secondary and safety outcomes were similar between groups. Conclusions: In this study, there was no statistically significant difference in length of stay in patients that received early SQ basal insulin. Larger trials are needed to determine the significance of earlier SQ basal insulin in DKA.

Prothrombin complex concentrate administration timing in warfarin-associated intracranial hemorrhage.

INTRODUCTION: Guidelines recommend "rapid" and "urgent" reversal of anticoagulation for warfarin-associated intracranial hemorrhage (ICH) treatment; however, they do not specify goals for time-to-administration. There are limited studies evaluating time to reversal, or international normalized ratio (INR) correction, on hematoma expansion and outcomes in intervals of <4 h. The purpose of this study was to evaluate the association of 4-factor prothrombin concentrate (4F-PCC) time-to-administration on rates of achieving effective hemostasis, determined by hematoma expansion, for treatment of warfarin-associated ICH. METHODS: This was a retrospective, observational, single center study performed at a large community teaching hospital. Patients were stratified into three groups based on time of CT diagnosis of ICH to administration of 4F-PCC: <45 min, 45-90 min, and >90 min. The primary outcome was rates of achieving effective hemostasis in each group defined as a ≤20% increase in hematoma volume as estimated by a radiologist. RESULTS: A total of 227 patients were screened for inclusion with ultimately 39 being included. Baseline characteristics were similar between groups. The primary outcome was not significantly different among groups stratified by time to 4F-PCC administration of <45 min, 45-90 min, and >90 min (85.7% vs 73.3% vs 90%, p value 0.514). There was no difference among secondary outcomes between groups including in-hospital mortality, hospital length of stay (LOS), and intensive care unit LOS. CONCLUSION: There was no association with time-to-administration of 4F-PCC on rates of hemostasis achievement, defined as hematoma expansion of ≤20%, identified in this study.

What are we waiting for? A review of early basal insulin therapy in diabetic ketoacidosis management.

Diabetic ketoacidosis (DKA) remains a significant challenge for healthcare systems due to prolonged lengths of stay and rising costs. The current American Diabetes Association (ADA) guidelines recommend starting basal insulin after resolution of DKA. However, these guidelines have not been updated since 2009, which can potentially limit optimal care. Meanwhile, the Joint British Society guidelines on DKA management, which were more recently updated in March 2023, do advocate for early administration of basal insulin in their treatment algorithm. This article assesses the rationale and literature associated with the recommendation for early basal insulin administration in the management of DKA. Benefits of early basal insulin in this cohort appears to be associated with less rebound hyperglycemia, reduction in time to DKA resolution, reduced intravenous insulin requirements, and reduced length of stay without associated increases in hypoglycemic or hypokalemic events.

Indirect antiplatelet effects of rivaroxaban in a patient with intracranial hemorrhage: An underappreciated coagulopathy of factor Xa inhibitors?

Rivaroxaban is a direct oral anticoagulant (DOAC) used for prophylaxis and treatment of many prothrombotic states. The anticoagulation effects of rivaroxaban are produced by selectively binding and inhibiting factor Xa, causing delayed thrombin generation. Additionally, the delay in thrombin generation produces an indirect, dose dependent antiplatelet effect via reduction in tissue factor platelet aggregation. As with any anticoagulant, rivaroxaban use increases a patient's risk for major and minor hemorrhagic events. With mortality rates reported as high as 25% for those who experience an intracranial hemorrhage (ICH), immediate mitigation of hematoma and hemorrhage volume expansion is imperative. Management strategies include utilizing prothrombin complex concentrates (PCC) and factor Xa inhibitor specific antidotes, such as coagulation factor Xa recombinant, inactivated-zhzo. Routine monitoring or management of DOAC induced antiplatelet effects is ill-defined and not a part of routine standard of care. We report the first case, to our knowledge, of rivaroxaban's indirect antiplatelet effects identified by platelet function assays and managed with four-factor PCC and desmopressin in a patient experiencing an ICH. Further exploration is needed to determine the true clinical impact attributed to rivaroxaban's antiplatelet effects.

Anticoagulation Monitoring in the Intensive Care Unit.

Patients with critical illness often display variable hypo- and hypercoagulable sequalae requiring intense monitoring and anticoagulation pharmacotherapy to prevent or treat inappropriate clot formation. It is imperative to understand the various stages of the clotting cascade and where each pharmacotherapy agent exerts its therapeutic effect. Common coagulation tests are utilized to monitor the areas of the clotting cascade and the effects that anticoagulant pharmacotherapy exhibits. Many novel coagulation tests are also in development. The purpose of this narrative review is to evaluate commonly utilized coagulation tests that monitor anticoagulation while in the intensive care unit.

Successful Use of Aspirin, Apixaban, and Viscoelastography in a Patient with Severe COVID Disease and Allergy to Porcine Products.

Coagulation abnormalities are frequently described in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Common thromboprophylaxis and anticoagulation treatment strategies include the use of heparinoid therapy. We describe a 57-year-old woman with an allergy to porcine products that was started on apixaban for anticoagulation therapy given her allergy profile and need for venous thromboembolism prophylaxis. Apixaban and aspirin therapy were optimized with the support of serial viscoelastography and platelet function assays. Our patient experienced respiratory failure requiring intubation for 7 days but was successfully weaned to room air, tolerated a regular diet, and ultimately discharged to home after a 17-day hospital course. Here we report the safe and successful use of aspirin, apixaban, and viscoelastography for COVID-19-associated coagulopathy.

Modified version of the American College of Cardiology's recommendation for low-dose prothrombin complex concentrate is effective for warfarin reversal.

BACKGROUND: Dosing of four factor prothrombin complex concentrate (4PCC) for warfarin reversal remains controversial. Recently, the American College of Cardiology (ACC) recommended a low-dose PCC regimen as an option for warfarin reversal in acute major bleeding. We performed a retrospective study evaluating if a modified version of the ACC guideline recommendations was effective for warfarin reversal in acute major bleeds when compared to traditional variable dosing. METHODS: This was a retrospective cohort study of patients who received 4PCC for warfarin reversal in a 12 month period. We included patients that were ≥18 years of age, received 4PCC for warfarin reversal, and had an initial International Normalized Ratio (INR) of >2. Our primary outcome was the number of patients who had a post-4PCC infusion INR of <1.6. RESULTS: A total of 60 patients were included in the final analysis with 30 patients stratified to the traditional dosing and low-dose groups, respectively. Patient demographics were similar between both groups. We found no difference in the number of patients who had a post-4PCC infusion INR <1.6 between the traditional dosing and low dosing group (90.0% vs. 86.7%; p = 0.68). Additionally, we found no difference between post-infusion median INRs in each group (1.35 vs. 1.30; p = 0.16). Approximately 1000 units per patient were spared when utilizing the low-dose regimen. CONCLUSION: A modified version of the ACC's low-dose 4PCC option for warfarin reversal achieves similar outcomes for lowering INR values compared to traditional variable dosing regimens.

Tracing the Lines: A Review of Viscoelastography for Emergency Medicine Clinicians.

BACKGROUND: Viscoelastography (VE) is an established method to identify coagulopathies in various disease processes. Clinical decisions can be made with real-time tracings and quantitative values at the bedside. Thromboelastography (TEG®) and rotational thromboelastometry (ROTEM®) have been utilized in several disease states with clinical varying success. OBJECTIVES: This review will summarize the literature and provide recommendations pertaining to major disease processes where VE may be beneficial, including trauma, anticoagulation reversal, liver disease, acute ischemic stroke, and acquired brain injuries. DISCUSSION: VE has a role in many emergency medicine patients encountered by clinicians. Reduced mortality, decreased blood product utilization, and prognostication ability makes VE an intriguing tool that can be utilized by providers to improve patient care. CONCLUSION: This review serves as a way for emergency medicine clinicians to utilize VE in their practice and provides an insightful literature overview.

Utilization of thromboelastography and a low molecular weight heparin anti-Xa assay for guidance in apixaban reversal: A case report.

Reversal of oral factor Xa (FXa) inhibitors, such as apixaban, remains a controversial topic. However, the controversy goes beyond what reversal agent to utilize. Often times these patients present with an acute major bleed and are difficult to assess whether reversal is warranted or not. Furthermore, it is difficult to assess whether reversal was successful in a timely manner. A paucity of literature exists regarding the utilization of low molecular weight heparin (LMWH) anti-Xa assays and thromboelastography for identifying coagulopathies associated with oral FXa inhibitors. We report a case of apixaban induced coagulopathy utilizing thromboelastography and a LMWH anti-Xa assay as a guide for reversal.

Pharmacoeconomic impact of an alternative workflow process for stroke.

OBJECTIVE: The objective of this study was to evaluate a new multidisciplinary process in which intravenous alteplase (tPA) waste, used for acute ischemic stroke (AIS), was salvaged in an attempt to maximize cost effectiveness without impacting door-to-needle (DTN) administration times. DESIGN: This was a retrospective cohort between May 2017 and February 2018. The primary endpoint evaluated for this study was the total tPA salvaged and total cost savings in U.S. dollars. Secondary endpoints evaluated included overall DTN time in minutes. SETTING: Emergency department of a primary stroke center. PATIENTS: A convenience sample of sequential adult (>18 years) patients who received tPA in the ED for AIS were included for analysis. INTERVENTIONS: New stroke process which involved bedside mixing of tPA and salvaging of excess waste in the main central pharmacy. MEASUREMENTS AND MAIN RESULTS: A total of 50 patients were included in the final analysis. There were 25 patients included in the new process and old process groups respectively. A total of 605 mg of alteplase was salvaged from 25 patients in the new process group which was associated with an estimated cost savings of over $120,000 annually. Patients in the new process group had statistically faster average (52 min vs. 60 min; p = 0.01) and median (50 min vs. 58 min; p = 0.03) DTN administration times. CONCLUSION: Preliminary data, in this pilot study, utilizing a multidisciplinary model for tPA administration led to significant cost savings of tPA and decreases in overall DTN administration times.
