Staff Safety Alert Banner Program Against Workplace Violence at an Urban American Hospital.

BACKGROUND: Workplace violence (WPV) in healthcare has become an issue worldwide, with increasing prevalence after the COVID-19 pandemic. Notably, WPV in any setting has individual and systemic repercussions. However, despite extensive literature reporting the prevalence of WPV in healthcare worldwide, effective, standardized prevention policies have not been established. We developed and piloted a WPV initiative at an urban hospital in the state of Maryland. Here, we aim to describe our program development methods and implementation. METHODS: The 6-month program utilized a reporting tool developed within patients' electronic medical records (EMRs) to request the display of a Staff Safety Alert (SSA) banner to alert healthcare professionals of patients who engaged in violent behavior and are at increased risk of subsequent behavior. This tool was piloted on 21 patient care units. A review committee either approved or denied case requests filed by frontline workers, with holistic consideration involving patient status, potential biases, and communication flaws. RESULTS: Twenty-one banner requests were filed during the course of the pilot. Of which, eight were approved, and 13 were denied. The multi-trauma intermediate care floor filed the most case requests for a safety banner. CONCLUSIONS/APPLICATION TO PRACTICE: Our pilot program offers a patient-centered intervention program where extensive personnel training and patient-focused considerations were applied prior to the approval or denial of a banner display. The SSA program was the initial step in institutionally combatting WPV in healthcare as staff are encouraged to officially document unsafe events followed by careful action in response.

Distribution and concentration pathway of particulate pollution during pandemic-induced lockdown in metropolitan cities in India.

To characterize the pollutant dispersal across major metropolitan cities in India, daily particulate matter (PM10 and PM2.5) data for the study areas were collected from the National Air Quality Monitoring stations database provided by the Central Pollution Control Board (CPCB) of India. The data were analysed for three temporal ranges, i.e. before the pandemic-induced lockdown, during the lockdown, and after the upliftment of lockdown restrictions. For the purpose, the time scale ranged from 1st April to 31st May for the years 2019 (pre), 2020, and 2021 (post). Statistical distributions (lognormal, Weibull, and Gamma), aerosol optical thickness, and back trajectories were assessed for all three time periods. Most cities followed the lognormal distribution for PM2.5 during the lockdown period except Mumbai and Hyderabad. For PM10, all the regions followed the lognormal distribution. Delhi and Kolkata observed a maximum decline in particulate pollution of 41% and 52% for PM2.5 and 49% and 53% for PM10, respectively. Air mass back trajectory suggests local transmission of air mass during the lockdown period, and an undeniable decline in aerosol optical thickness was observed from the MODIS sensor. It can be concluded that statistical distribution analysis coupled with pollution models can be a counterpart in studying the dispersal and developing pollution abatement policies for specific sites. Moreover, incorporating remote sensing in pollution study can enhance the knowledge about the origin and movement of air parcels and can be helpful in taking decisions beforehand.

Continuation of Opioid Therapy at Transitions of Care in Critically Ill Patients.

PURPOSE: Opioids are one of the high-risk medication classes that are administered to critically ill patients during their intensive care unit (ICU) stay. However, little attention has been given to inpatient opioid prescribing practices, especially in critically ill patients. The purpose of our study was to characterize opioid prescribing practices across 2 transitions of care during an inpatient hospital stay: medical ICU (MICU)/intermediate care unit (IMC) to floor and floor to hospital discharge and identify potential patient-specific factors that impact opioid continuation. METHODS: This is a retrospective cohort study evaluating opioid-naive adult patients with new opioid therapy initiated in MICU/IMC at a tertiary care academic medical center from December 1, 2016, to November 30, 2017. Opioid continuation rate was assessed twice: transition 1 (MICU/IMC to floor) and transition 2 (floor to hospital discharge). RESULTS: In total, 112 opioid-naive patients with initial opioid administration in the MICU/IMC were included. Opioid therapy was continued in 56.1% (37/66) at transition 1 and 56.8% of patients (21/37) at transition 2. Patients with opioids continued at transition 1 had a longer hospital length of stay compared to those not continued on opioids, 22 (interquartile range [IQR] 11-36) vs 8 (IQR 6-14; P = .0004). Among the patients continued on opioids at hospital discharge, intubation during hospital stay and cumulative opioid dosage were greater than those not continued on opioids (17 [80.9%] vs 7 [43.8%], P = .019; and 3482 mcg [IQR 1690-9530] vs 732.5 mcg [IQR 187.5-1360.9], P = .0018, respectively). CONCLUSIONS: Opioid-naive patients receiving opioid therapy in the MICU/IMC had a continuation rate of >56% during transitions of care, including hospital discharge. Factors that contributed to the continuation of opioids at transitions of care included longer hospital length of stay, intubation, and cumulative hospital opioid dosage. These findings may help to provide health systems with guidance on targeted opioid stewardship programs.

Impact of an Antipsychotic Discontinuation Bundle During Transitions of Care in Critically Ill Patients.

INTRODUCTION:: Delirium affects a large proportion of patients admitted to the intensive care unit (ICU) and is associated with increased morbidity and mortality. Antipsychotics have become frequently used agents for the treatment of delirium; however, they are often continued at transitions of care. This has potential negative short- and long-term health consequences that are preventable. We investigated the antipsychotic tapering bundle's impact on the rate of antipsychotic continuation at transitions from the medical intensive care unit (MICU). METHODS:: This was a preretrospective and postretrospective chart review that included adult patients in the MICU initiated on antipsychotic therapy for ICU delirium. A bundled multidisciplinary education program and antipsychotic discontinuation algorithm were implemented in the MICU to provide recommendations for safe and effective use of antipsychotics for ICU delirium and minimize continuation of therapy at transitions of care. Rates of antipsychotic continuation at transition from the MICU were compared between the preintervention and postintervention groups with the χ2 test. RESULTS:: A total of 140 patients in the prebundle group and 141 patients in the postbundle group were enrolled. Overall, baseline characteristics were similar. After implementation of the discontinuation bundle, antipsychotic continuation at MICU discharge decreased (27.9% in the prebundle group vs 17.7% in the postbundle group; P < .05). In the multivariate analysis, patients were less likely to be continued on antipsychotic therapy at MICU discharge after implementation of the bundle (odds ratio [OR]: 0.47; 95% confidence interval [CI]: 0.26-0.86). There were also lower rates of overall antipsychotic continuation at hospital discharge (OR: 0.4; 95% CI: 0.18-0.89). CONCLUSION:: This is the first study to demonstrate a reduction in antipsychotic continuation at transition from the MICU after implementation of an antipsychotic discontinuation bundle in ICU patients. We believe this bundle allows for safer transitions of care from the MICU and decreases unnecessary antipsychotic therapy.

Measurement of adult antimicrobial drug use in tertiary care hospital using defined daily dose and days of therapy.

Widespread overuse and inappropriate use of antimicrobial drugs continues to fuel an increase in antimicrobial resistance and leads to consequent treatment complications and increased healthcare costs. In the present study we aimed to describe antimicrobial drug consumption and predictors and to identify potential targets for antimicrobial stewardship. This was a prospective observational study conducted at adult medicine wards of tertiary care teaching hospital over the period of five months. Antimicrobial drug consumption was measured using days of therapy per 1000 patient days and defined daily dose per 1000 patient days. Additionally, predictors of multiple antimicrobial prescribing were also analyzed. Seven hundred thirty patients were screened and 550 enrolled, receiving 1,512 courses of antimicrobial therapy, mainly intravenously (66%). Most frequently prescribed agents were artesunate (13%), ceftriaxone (11%) and metronidazole (10.5%). Overall consumption was 1,533 days of therapy per 1000 patient days and was mainly attributed to antibiotics (98.3%) for empirical therapy (50%). Median days of antimicrobial drugs prescribing were 3 (inter quartile range 2-5). Most commonly consumed antimicrobials were ceftriaxone (31%, 248.8 g) and artesunate (26%, 29 g). Antimicrobials contributed to 72.5% expense of the total incurred. Multivariate analysis reveals that younger patients (≥45 years) (odds ratio: 1.59, 95% CI 1.14-2.21) were more likely and absence of comorbidities (odds ratio: 0.58, 95% CI 0.42-0.79) and shorter hospital stay (≥6 days)(odds ratio: 0.44, 95% CI 0.32-0.60) were associated with less likelihood of prescribing multiple antimicrobial drugs. Estimating antimicrobial drugs use by defined daily dose method will remain open to criticism because the prescribed dosage is not often in agreement with the "usual" daily dose, which depends on location of and susceptibility of pathogenic organisms and metabolic status of the patient.

Urgent endovascular revascularization for symptomatic intracranial atherosclerotic stenosis.

BACKGROUND: Endovascular revascularization for intracranial atherosclerotic stenoses is being increasingly performed at major medical centers and has been reported to be technically feasible and safe. The authors report their experience with patients who underwent such a procedure for impending stroke and neurologic instability. METHOD: All 18 patients (21 intracranial lesions) treated between 1997 and 2002 at the authors' institution with endovascular revascularization were retrospectively reviewed. Each patient had failed maximal medical therapy and was thought to be at high risk for an imminent stroke. RESULTS: Endovascular revascularization was performed on eight distal internal carotid artery lesions, six middle cerebral artery lesions, four intracranial vertebral artery lesions, and three basilar artery lesions. Recanalization was complete in 5 arteries (Thrombolysis in Myocardial Infarction [TIMI] Grade III), partial in 14 arteries (TIMI Grade II), and complete occlusion (TIMI 0) developed in 1 artery. In a patient with a tight basilar stenosis, no angioplasty could be performed because of the inability to cross the stenosis with the guidewire. Major periprocedural complications occurred in 9 (50%) patients: intracranial hemorrhage in 3 (17%), disabling ischemic stroke in 2 (11%), and major extracranial hemorrhage in 4 (22%). Three patients died: one from intracerebral hemorrhage and two from cardiorespiratory failure. CONCLUSIONS: Endovascular revascularization of intracranial vessels is technically feasible and may be performed successfully. However, periprocedural complication and fatality rates in neurologically unstable patients are high. The results suggest that patient selection, procedure timing, and periprocedural medical management are critical factors to reduce periprocedural morbidity and mortality.

Rheolytic thrombectomy of acute stent thrombosis of cervical vertebral artery. Case report and literature review.

SUMMARY: A new Xpeedior rheolytic thrombectomy catheter has been successfully used to extract thrombus from an acutely thrombosed vertebral artery stent without apparent distal embolism. The ease of use and the speed of thrombectomy suggest that this system may be useful for the treatment of acute ischemic stroke.

Cerebrovascular angioplasty and stenting for the prevention of stroke.

Until recently, stroke preventive strategies have focused on either medical regimens aimed at antagonizing or reversing atherosclerosis, or surgical intervention for revascularization of the cerebrovascular system. However, with the advent of rapidly emerging microcatheterization techniques and technology, endovascular surgical revascularization of the brain is rapidly emerging as a powerful therapeutic modality. In particular, significant advances already have been made in revascularization of the extracranial carotid artery and many common anatomic sites of intracranial athero-occlusive disease, using special adaptations of conventional percutaneous angioplasty and stenting techniques. This paper reviews the cumulative experience with these emerging techniques, with a particular emphasis on clinical outcomes and future directions. It also reports the substantial cumulative institutional experience of the authors over the past 18 months with both extracranial carotid and intracranial artery stent-assisted carotid angioplasty.

Early clinical experience with a dedicated portable computed tomography scanner in a biplane neuroangiography suite: assessment of feasibility and utility in neurointerventional practice.

SUMMARY: The ability to have on-site access to cross-sectional imaging in a biplane neuroangiography suite has tremendous potential for enhancing current neurointerventional practice.Although a few prototypical multimodality suites have been created, several problems/limitations have prevented widespread implementation. Recently, a portable CT scanner has been developed, which may overcome previous shortcomings. We review our recent clinical experience with this new modality, exploring numerous adjunctive diagnostic and therapeutic applications. Forty-one patients underwent periprocedural CT using the Tomoscan M/EG portable CT (Philips). The portable CT scanner is kept at the "head-end" of the biplane neuroangiography suite, being moved into position as needed before, after, or during a procedure. A pivoting angiographic table permits excellent z-plane mobility for rapid gantry to fluoroscopy positioning. Five mm slices at five mm increments were obtained. High quality images were obtained in all cases. The portable CT scanner could be quickly positioned and activated within five min. Total scanning time for a typical case, including initial positioning and set-up was 10-12 min. Twelve of 41 cases were performed adjunctively during diagnostic angiography; 29/41 were performed in an interventional setting.Twenty of 29 scan evaluated baseline or post-therapeutic status of the brain (e.g., Guglielmi detachable coil aneurysm obliteration, arteriovenous malformation (AVM) embolisation, local thrombolysis); 9/29 provided cross-sectional guidance to various interventions (direct puncture embolisation, percutaneous vertebroplasty, spinal biopsy, discography). Use of the portable CT scanner permitted rapidly accessible high quality cross sectional imaging within the biplane neuroangiography suite, which augmented diagnostic and therapeutic decision-making, and therapeutic intervention.

Evolving experience with direct puncture therapeutic embolization for adjunctive and palliative management of head and neck hypervascular neoplasms.

OBJECTIVES: The use of percutaneous, direct puncture therapeutic embolization (DPTE) of hypervascular head and neck neoplasms is a relatively new modality that may be used to supplement or supplant conventional endovascular transarterial embolization. Although the preliminary clinical experience reported by a single group has been favorable, extensive case series experience is lacking. This prompted us to review our recent clinical experience with these techniques to determine safety, efficacy, and emerging role in the overall neurointerventional therapeutic armamentarium. STUDY DESIGN: A retrospective analysis of the previous 34 consecutive cases of hypervascular tumors undergoing DPTE referred to our service for therapeutic devascularization was performed. METHODS: Complete case record review was undertaken. Twenty-six of 34 cases involved DPTE of head and neck neoplasms. Conventional diagnostic angiography was performed for therapeutic planning and to assist in precise localization. When performed, standard microcatheter transarterial embolization techniques were used either before or after attempted DPTE. Cyanoacrylate embolic mixtures (n-butyl cyanoacrylate [NBCA], lipiodol, powdered tungsten) were used in 21 of 24 cases, and absolute ethanol in 3 of 24. Direct puncture angiography of the targeted tumor neovasculature was always performed before DPTE. RESULTS: Twenty-four of 26 cases had technically successful DPTE. Combined transarterial embolization with DPTE was used in 16 of 24 cases, although for the last 12 cases, 9 were treated predominantly or exclusively by DPTE. There were no major or minor clinical complications, and there was one asymptomatic technical complication. Total or near-total devascularization was achieved in all cases. All preoperative cases had excellent hemostasis within the resected tumor bed. CONCLUSIONS: Our results lend further support to the safety and efficacy of DPTE in the management of hypervascular neoplasms of the head and neck. With our increasing experience, this technique is evolving into a primary therapeutic modality for optimal tumor devascularization.

Use of mechanical thrombolysis via microballoon percutaneous transluminal angioplasty for the treatment of acute dural sinus thrombosis: case presentation and technical report.

OBJECTIVE AND IMPORTANCE: Although conventional superselective chemical thrombolysis is frequently successful for the treatment of severe acute dural sinus thrombosis, the technique has limitations and risks. This prompted us to develop a supplemental technique for achieving more rapid recanalization, using coronary microballoon percutaneous transluminal angioplasty catheters. We describe a successful application of this technique and technology that has not been previously reported. CLINICAL PRESENTATION: After several days of severe headaches, photophobia, and vomiting, a 29-year-old woman presented with rapidly progressive neurological deficits secondary to complete occlusion of the superior sagittal sinus (SSS) and right transverse/sigmoid sinus complex. Owing to her rapid neurological decline, she was referred for emergency endovascular intervention. TECHNIQUE: Initially, superselective chemical thrombolysis of the SSS was performed using urokinase. However, because of the extensive nature of the thrombus and lack of initial therapeutic response, we elected to attempt mechanical thrombolysis with various coronary percutaneous transluminal angioplasty microballoon catheters. This was accomplished by initial coaxial positioning of the device into an occluded segment, followed by gentle inflation and retraction of the device along the course of the right transverse sinus and/or SSS. These maneuvers were repeated with balloons of increasingly large diameter. Near-complete restoration of venous outflow was obtained within the SSS with preferential runoff into the left transverse sinus. The right transverse sinus was only partially recanalized. Despite the patient's rapid neurological decline on presentation, she experienced a dramatic clinical recovery with near-complete reversal of neurological deficits within 24 hours of intervention. CONCLUSION: This report shows the feasibility of performing safe and effective mechanical thrombolysis with percutaneous transluminal angioplasty coronary balloon microcatheters within the major dural sinuses. This technique can probably accelerate clot disruption and thrombolysis, possibly resulting in a more rapid restoration of venous flow.

Multichannel fenestrations of the petrous segment of the internal carotid artery.

Multichannel fenestration of the internal carotid artery (ICA) is a rare, previously unreported developmental anomaly with unknown clinical significance. Although previously thought to have distinct embryologic origins, the presence of multiple channels in a short-segment fenestration favors a common developmental pathway for the origin of duplications and fenestrations: the persistence of a plexiform vascular network from the 4-mm to 5-mm embryologic stage of development.
