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.

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.

Multicenter comparison of antiplatelet treatment strategies for urgent/emergent neuroendovascular stenting.

BACKGROUND: Emergent neuroendovascular stenting presents challenges for the utilization of antiplatelet agents. METHODS: This was a multicenter, retrospective cohort of patients who underwent emergent neuroendovascular stenting. The primary endpoints were thrombotic and bleeding events in relation to the timing of antiplatelet administration, route of administration, and choice of intravenous (IV) agent and the study investigated practice variability in antiplatelet utilization. RESULTS: Five-hundred and seventy patients were screened across 12 sites. Of those, 167 were included for data analysis. For patients who presented with ischemic stroke, artery dissection and emergent internal carotid artery (ICA) stenting who received an antiplatelet agent prior to or during the procedure, 57% were given an IV antiplatelet agent; for patients who were given an antiplatelet agent after the procedure, 96% were given an oral agent. For patients who presented for aneurysm repair and received an antiplatelet agent prior to or during the procedure, 74% were given an IV agent; patients who were given an antiplatelet agent after the completion of the procedure were given an oral antiplatelet agent 90% of the time. In patients who presented with ischemic stroke, artery dissection and emergent ICA stenting who received oral antiplatelet agents post-procedure were more likely to have thrombotic events compared to those who received oral antiplatelet agents prior to or during the procedure (29% vs 9%; p = 0.04). There were no differences in the primary outcomes observed when comparing other antiplatelet treatment strategies. CONCLUSION: The optimal timing of antiplatelet administration in relation to stent placement and route of administration of antiplatelet agents is unclear. Timing and route of administration of antiplatelet agents may have an effect on thrombosis in emergent neuroendovascular stenting. Significant practice variation exists in antiplatelet agent utilization in emergent neuroendovascular stenting.

Characterization of Medication Discrepancies and Interventions Resulting From Pharmacy-Led Medication Reconciliation in the Critical Care Setting.

BACKGROUND: Medication reconciliation has been shown to reduce medication-related errors in hospitalized patients, but the impact of pharmacy-led medication reconciliation in the intensive care unit (ICU) has not been extensively studied. METHODS: This was a retrospective chart review of patients with a pharmacy-led medication reconciliation on admission to an ICU between January 1st and March 31st, 2018. Pharmacy-led medication reconciliations were completed by pharmacists, pharmacy residents, and pharmacy students. The objective of this study was to describe medication discrepancies identified by pharmacy-led medication reconciliation and to evaluate the interventions following. RESULTS: A total of 288 patients were screened and 247 met inclusion criteria. There were 1148 medication discrepancies identified resulting in an average of 4.65 discrepancies per patient. Medication addition (54.25%) and medication deletion (45.75%) were most common. Within 24 hours of medication reconciliation, 214 interventions were made to active orders. No differences were observed between discrepancies identified and type of pharmacy staff completing the medication reconciliation. CONCLUSIONS: This study identified a high rate of medication discrepancies on admission to the ICU. Furthermore, it describes the types of pharmacist interventions following pharmacy-led medication reconciliation. This process may be impactful to incorporate as a standard practice in ICUs and warrants further investigation into value, cost, and pharmacist workflow.

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.

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.

Evaluation of Dexmedetomidine's Effect on Temperature in Obese Critically Ill Patients.

INTRODUCTION: Previous literature showed an association between hyperthermia and dexmedetomidine (DEX) use for ongoing sedation in non-obese patients. The purpose of this study is to evaluate DEX's effect on temperature in obese critically ill patients. METHODS: This single center, retrospective, cohort study included patients ≥18 years, admitted to a surgical or medical ICU, received DEX for ≥8 hours as a single continuous infusion sedative, and weighed ≥120% of ideal body weight. Patients were excluded if they had a fever (≥38°C) and positive cultures within 48 hours of DEX initiation. The primary endpoint was a fever (Tmax of ≥38°C) within 48 hours of DEX initiation. RESULTS: A total of 186 patients were included for evaluation. Forty-two patients (22.5%) had a fever during the first 48 hours of DEX initiation. Median weight was not different between the febrile and afebrile groups (99.4 [90.6-122.4] vs 97.6 [81.6-114.2] kg, P = .6). Median change from baseline temperature for all patients within 48 hours was an increase of .5 (.1-.8) °C, P < .001. In multiple regression analysis, duration of DEX and baseline temperature were the only significant predictors of fever development with an adjusted odds ratio of 1.041 (95% CI 1.009-1.074, P = .012) and 7.058 (95% CI 3.307-15.064, P < .001), respectively. CONCLUSIONS: This study suggests that there is a significant increase in body temperature from baseline for obese patients on DEX. Duration of DEX and baseline temperature were found to be risk factors for fever development in this population. Further studies are warranted.

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.

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.

Effect of desmopressin acetate on acute spontaneous intracranial hemorrhage in patients on antiplatelet therapy.

PURPOSE: To evaluate the impact of desmopressin acetate (DDAVP) on poor outcomes, hematoma expansion, and adverse events in patients diagnosed with a non-traumatic, antiplatelet-associated intracranial hemorrhage (ICH). METHODS: This was a multicenter, retrospective, propensity-matched cohort study comparing DDAVP to control in patients diagnosed with a non-traumatic ICH previously on antiplatelet therapy. Notable exclusion criteria included admission to trauma service, subarachnoid hemorrhages, confounding coagulopathic factors, and hematoma evacuation. Poor outcome, defined as discharge to hospice or in-patient mortality, was the primary outcome. Secondary outcomes included intracranial hematoma expansion and occurrence of adverse events, which included hyponatremia and thromboembolic events. RESULTS: A total of 49 patients receiving DDAVP were compared to 107 controls in the unmatched cohort. Thirty-seven patients treated with DDAVP and 55 controls were included in the propensity-matched analysis, which was adjusted for age, ethnicity, history of diabetes, receipt of platelet transfusion, and thromboembolism prophylaxis. Poor outcome (16.2% DDAVP vs 29% control, p = 0.13), rates of hematoma expansion (11.8% DDAVP vs 11.1% control, p = 0.99), and adverse events (21.6% DDAVP vs 20% control, p = 0.99) were statistically similar between the matched groups. CONCLUSIONS: DDAVP administration in patients with spontaneous antiplatelet-associated ICH was not associated with a reduction in poor outcomes, hematoma expansion, or an increase in adverse events. Use of DDAVP in this patient population appears to be safe. Larger prospective studies are warranted to evaluate DDAVP utility in this patient population.

Evaluation of energy intake compared with indirect calorimetry requirements in critically ill patients with acute brain injury.

BACKGROUND: Nutrition support in critically ill patients with acute brain injury is vitally important because of known hypermetabolism. We aimed to describe energy and protein intake within the first 72 h in a broad neurocritical care population and compare energy intake with the indirect calorimetry (IC) resting energy expenditure (REE) target. METHODS: IC data, daily energy, and protein intake were collected through chart review over the first 7 days of hospital admission. We evaluated the type and amount of tube-feed product received, volume of propofol (1.1 kcal/ml) and clevidipine (2 kcal/ml), and amount of supplemental protein received. RESULTS: Ninety-one patients were included, with the majority presenting with either intracerebral hemorrhage (35.2%) or acute ischemic stroke (26.4%). The median day of admission on which IC was completed and enteral nutrition was initiated was day 3 (2-5) and day 1 (1-2), respectively. The difference in kilocalories received compared with IC REE target within the first 72 h was significantly different (2831 kcal [1663-4072] vs 4275 kcal [3450-5811]; Z = -6.469; P < .001). The median kilocalories received as tube feeds during the first 72 h was 88% (55%-99%), and the mean protein received in the first 72 h was 0.7 ± 0.5 g/kg/day. CONCLUSION: In this population, patients had lower energy intake compared with their energy needs determined by IC during the first 72 h of admission but attained 7-day goals. Future studies should investigate barriers to improve energy delivery in this patient population.

Supraprophylactic Anti-Factor Xa Levels Are Associated with Major Bleeding in Neurosurgery Patients Receiving Prophylactic Enoxaparin.

BACKGROUND: Prior studies demonstrated reduced risk for venous thromboembolism (VTE) in neurosurgical patients secondary to prophylaxis with both heparin and low-molecular-weight heparin. The ability to monitor low-molecular-weight heparin by obtaining anti-factor Xa (anti-Xa) serum levels provides an opportunity to evaluate safety and efficacy. The aim of this study was to describe characteristics of patients who have anti-Xa levels outside of the goal range (0.2-0.4/0.5 IU/mL) and investigate incidence of major bleeding and VTE. METHODS: A single-center, retrospective, observational study was conducted on neurosurgical patients receiving enoxaparin for VTE prophylaxis between August 2019 and December 2020. Significance testing was conducted via Fisher exact test and independent samples t test. RESULTS: The study included 85 patients. Patients were less likely to have an anti-Xa level in the goal range if they were male, had a higher weight, or were morbidly obese. Three neuroendovascular patients (3.5%) experienced a major bleed. Serum anti-Xa levels were significantly higher in patients who experienced major bleeds compared with patients who did not (0.45 ± 0.16 IU/mL vs. 0.28 ± 0.09 IU/mL, P = 0.003). Patients with a supraprophylactic anti-Xa level (>0.5 IU/mL) were more likely to experience a major bleed (P = 0.005). One VTE event occurred: the patient experienced a pulmonary embolism with anti-Xa level at goal. CONCLUSIONS: Anti-Xa-guided enoxaparin dosing for VTE prophylaxis in neurosurgical patients may help prevent major bleeding. These data suggest that a higher anti-Xa level may predispose patients to major bleeding. Further evaluation is needed to identify the goal anti-Xa level for VTE prophylaxis in this population.

Machine Learning in Action: Stroke Diagnosis and Outcome Prediction.

The application of machine learning has rapidly evolved in medicine over the past decade. In stroke, commercially available machine learning algorithms have already been incorporated into clinical application for rapid diagnosis. The creation and advancement of deep learning techniques have greatly improved clinical utilization of machine learning tools and new algorithms continue to emerge with improved accuracy in stroke diagnosis and outcome prediction. Although imaging-based feature recognition and segmentation have significantly facilitated rapid stroke diagnosis and triaging, stroke prognostication is dependent on a multitude of patient specific as well as clinical factors and hence accurate outcome prediction remains challenging. Despite its vital role in stroke diagnosis and prognostication, it is important to recognize that machine learning output is only as good as the input data and the appropriateness of algorithm applied to any specific data set. Additionally, many studies on machine learning tend to be limited by small sample size and hence concerted efforts to collate data could improve evaluation of future machine learning tools in stroke. In the present state, machine learning technology serves as a helpful and efficient tool for rapid clinical decision making while oversight from clinical experts is still required to address specific aspects not accounted for in an automated algorithm. This article provides an overview of machine learning technology and a tabulated review of pertinent machine learning studies related to stroke diagnosis and outcome prediction.

PHarmacist Avoidance or Reductions in Medical Costs in CRITically Ill Adults: PHARM-CRIT Study.

To comprehensively classify interventions performed by ICU clinical pharmacists and quantify cost avoidance generated through their accepted interventions. DESIGN: A multicenter, prospective, observational study was performed between August 2018 and January 2019. SETTING: Community hospitals and academic medical centers in the United States. PARTICIPANTS: ICU clinical pharmacists. INTERVENTIONS: Recommendations classified into one of 38 intervention categories (divided into six unique sections) associated with cost avoidance. MEASUREMENTS AND MAIN RESULTS: Two-hundred fifteen ICU pharmacists at 85 centers performed 55,926 interventions during 3,148 shifts that were accepted on 27,681 adult patient days and generated $23,404,089 of cost avoidance. The quantity of accepted interventions and cost avoidance generated in six established sections was adverse drug event prevention (5,777 interventions; $5,822,539 CA), resource utilization (12,630 interventions; $4,491,318), individualization of patient care (29,284 interventions; $9,680,036 cost avoidance), prophylaxis (1,639 interventions; $1,414,465 cost avoidance), hands-on care (1,828 interventions; $1,339,621 cost avoidance), and administrative/supportive tasks (4,768 interventions; $656,110 cost avoidance). Mean cost avoidance was $418 per intervention, $845 per patient day, and $7,435 per ICU pharmacist shift. The annualized cost avoidance from an ICU pharmacist is $1,784,302. The potential monetary cost avoidance to pharmacist salary ratio was between $3.3:1 and $9.6:1. CONCLUSIONS: Pharmacist involvement in the care of critically ill patients results in significant avoidance of healthcare costs, particularly in the areas of individualization of patient care, adverse drug event prevention, and resource utilization. The potential monetary cost avoidance to pharmacist salary ratio employing an ICU clinical pharmacist is between $3.3:1 and $9.6:1.

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.

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.

Use of Continuous Glucose Monitor in Critically Ill COVID-19 Patients Requiring Insulin Infusion: An Observational Study.

CONTEXT: The coronavirus disease 2019 (COVID-19) pandemic has created a need for remote blood glucose (BG) monitoring in the intensive care unit (ICU). OBJECTIVE: To evaluate feasibility and patient safety of a hybrid monitoring strategy of point-of-care (POC) BG plus continuous glucose monitor (CGM) in the ICU. DESIGN: Retrospective analysis. SETTING: ICU of an academic medical center. PATIENTS: Patients with COVID-19 on IV insulin. INTERVENTION: After meeting initial validation criteria, CGM was used for IV insulin titration and POC BG was performed every 6 hours or as needed. MAIN OUTCOME MEASURES: Outcomes included frequency of POC BG, workflow, safety, and accuracy measures. RESULTS: The study included 19 patients, 18 with CGM data, mean age 58 years, 89% on mechanical ventilation, 37% on vasopressors, and 42% on dialysis. The median time to CGM validation was 137 minutes (interquartile range [IQR] 114-206). During IV insulin, the median number of POC values was 7 (IQR 6-16) on day 1, and declined slightly thereafter (71% reduction compared with standard of 24/day). The median number of CGM values used nonadjunctively to titrate IV insulin was 11.5 (IQR 0, 15) on day 1 and increased thereafter. Time in range 70 to 180 mg/dL was 64 ± 23% on day 1 and 72 ± 16% on days 2 through 7, whereas time <70 mg/dL was 1.5 ± 4.1% on day 1 and <1% on days 2 through 7. CONCLUSIONS: This study provides data to support that CGM using a hybrid protocol is feasible, accurate, safe, and has potential to reduce nursing and staff workload.

PHarmacist Avoidance or Reductions in Medical Costs in Patients Presenting the EMergency Department: PHARM-EM Study.

To comprehensively classify interventions performed by emergency medicine clinical pharmacists and quantify cost avoidance generated through their accepted interventions. DESIGN: A multicenter, prospective, observational study was performed between August 2018 and January 2019. SETTING: Community and academic hospitals in the United States. PARTICIPANTS: Emergency medicine clinical pharmacists. INTERVENTIONS: Recommendations classified into one of 38 intervention categories associated with cost avoidance. MEASUREMENTS AND MAIN RESULTS: Eighty-eight emergency medicine pharmacists at 49 centers performed 13,984 interventions during 917 shifts that were accepted on 8,602 patients and generated $7,531,862 of cost avoidance. The quantity of accepted interventions and cost avoidance generated in six established categories were as follows: adverse drug event prevention (1,631 interventions; $2,225,049 cost avoidance), resource utilization (628; $310,582), individualization of patient care (6,122; $1,787,170), prophylaxis (24; $22,804), hands-on care (3,533; $2,836,811), and administrative/supportive tasks (2,046; $342,881). Mean cost avoidance was $538.61 per intervention, $875.60 per patient, and $8,213.59 per emergency medicine pharmacist shift. The annualized cost avoidance from an emergency medicine pharmacist was $1,971,262. The monetary cost avoidance to pharmacist salary ratio was between $1.4:1 and $10.6:1. CONCLUSIONS: Pharmacist involvement in the care of patients presenting to the emergency department results in significant avoidance of healthcare costs, particularly in the areas of hands-on care and adverse drug event prevention. The potential monetary benefit-to-cost ratio for emergency medicine pharmacists is between $1.4:1 and $10.6:1.

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.
