Implementation of low-intensity thrombolysis monitoring care in routine practice: process evaluation of the Optimal Post rtPA-IV Monitoring in Acute Ischemic Stroke (OPTIMISTmain) study in the United States.

INTRODUCTION: The ongoing OPTIMISTmain study, an international, multicenter, stepped-wedge cluster randomized trial, aims to determine effectiveness and safety of low-intensity versus standard monitoring in thrombolysis-treated patients with mild-to-moderate acute ischemic stroke (AIS). An embedded process evaluation explored integration and impact of the intervention on care processes at participating US sites. METHODS: A mixed-methods approach with quantitative and qualitative data were collected between September 2021 and November 2022. Implementer surveys were undertaken at pre- and post-intervention phases to understand the perceptions of low-intensity monitoring strategy. A sample of stroke care nurses were invited to participate in semi-structured interviews at an early stage of post-intervention. Qualitative data were analyzed deductively using the normalization process theory; quantitative data were tabulated. RESULTS: Interviews with 21 nurses at 8 hospitals have shown low-intensity monitoring was well accepted, as there were less time constraints and reduced workload for each patient. There were initial safety concerns over missing deteriorating patients and difficulties in changing established routines. Proper training, education, and communication, and changing the habits and culture of care, were key elements to successfully adopting the new monitoring care into routine practice. Similar results were found in the post-intervention survey (42 nurses from 13 hospitals). Nurses reported time being freed up to provide patient education (56%), daily living care (50%), early mobilization (26%), mood/cognition assessment (44%), and other aspects (i.e. communication, family support). CONCLUSIONS: Low-intensity monitoring for patients with mild-to-moderate acute ischemic stroke, facilitated by appropriate education and organizational support, appears feasible and acceptable at US hospitals.

Managing the Rehabilitation Wave: Rehabilitation Services for COVID-19 Survivors.

The coronavirus disease 2019 (COVID-19) pandemic is having a profound effect on the provision of medical care. As the curve progresses and patients are discharged, the rehabilitation wave brings a high number of postacute COVID-19 patients suffering from physical, mental, and cognitive impairments threatening their return to normal life. The complexity and severity of disease in patients recovering from severe COVID-19 infection require an approach that is implemented as early in the recovery phase as possible, in a concerted and systematic way. To address the rehabilitation wave, we describe a spectrum of interventions that start in the intensive care unit and continue through all the appropriate levels of care. This approach requires organized rehabilitation teams including physical therapists, occupational therapists, speech-language pathologists, rehabilitation psychologists or neuropsychologists, and physiatrists collaborating with acute medical teams. Here, we also discuss administrative factors that influence the provision of care during the COVID-19 pandemic. The services that can be provided are described in detail to allow the reader to understand what services may be appropriate locally. We have been learning and adapting real time during this crisis and hope that sharing our experience facilitates the work of others as the pandemic evolves. It is our goal to help reduce the potentially long-lasting challenges faced by COVID-19 survivors.

Nonpharmacological Treatments for Hospitalized Patients with Stroke: A Nuanced Approach to Prescribing Early Activity.

Stroke remains a leading cause of adult disability. To date, hyperacute revascularization procedures reach 5-10% of stroke patients even in high resource health systems. There is a limited time window for brain repair after stroke, and therefore, the activities such as prescribed exercise in the earliest period will likely have long-term significant consequences. Clinicians who provide care for hospitalized stroke patients make treatment decisions specific to activity often without guidelines to direct these prescriptions. This requires a balanced understanding of the available evidence for early post-stroke exercise and physiological principles after stroke that drive the safety of prescribed exercise. Here, we provide a summary of these relevant concepts, identify gaps, and recommend an approach to prescribing safe and meaningful activity for all patients with stroke. The population of thrombectomy-eligible stroke patients can be used as the exemplar for conceptualization.

Development and Implementation of a New Model of Care for Patients With Stroke, Acute Hospital Rehabilitation Intensive SErvices: Leveraging a Multidisciplinary Rehabilitation Team.

ABSTRACT: The optimal timing and intensity of early rehabilitation remain uncertain. The literature has stated that too early high-intensity mobility within 24 hours can result in poor outcomes as compared with the 24- to 48-hour poststroke (Stroke 2012;43:2389-94. Stroke 2004;35:1005-9). However, few studies have shown that mobilizing patients a few times per day can have positive results (Stroke 2004;35:1005-9. Cerebrovasc Dis 2010;29:352-60). In addition to mobility impairments, many patients after stroke have dysphagia, aphasia, and cognitive-linguistic deficits. To date, there is limited literature on early rehabilitation in these areas. Here, we describe a program of enhanced rehabilitation in the acute care hospital. In this enhanced model of care, our team delivers up to six sessions of therapy per day focused on the patient's deficits. A patient can receive up to two sessions of each discipline daily to include physical therapy, occupational therapy, and speech language pathology. The model emphasizes team collaboration between therapy disciplines, physiatry, nursing, and neurology accomplished through a daily therapy schedule, rehabilitation huddle, and direct communication before and after therapy sessions. With this model, we aim to enhance coordination of care resulting in improved patient satisfaction and, ultimately, recovery.

Feasibility of an Enhanced Therapy Model of Care for Hospitalized Stroke Patients.

INTRODUCTION: The aim of this study was to determine the safety and feasibility of an enhanced therapy model for hospitalized stroke patients. METHODS: This was a quasi-experimental cohort study of acute stroke patients from a single hospital. In the intervention group, all hospitalized patients on the acute stroke service were seen by at least two therapy disciplines daily in addition to routine stroke care. The comparison group consisted of all patients admitted to the same stroke service 1 year before who received the standard of care. The primary endpoint was the number of completed therapy sessions. Exploratory endpoints compared the length of hospital stay, hospital readmission rates, and degree of disability measured by the 90-day modified Rankin Scale score. RESULTS: A total of 1110 records were analyzed with 553 subjects in the intervention group and 557 in the control group. The intervention group received a significantly higher number of therapy sessions. There was no significant difference in length of hospital stay. However, 30-day readmission rates were lower, and the percentage of patients who achieved a good functional outcome on the modified Rankin Scale was higher during the intervention period. CONCLUSION: Increasing exposure to intensive multidisciplinary therapy comparable with that of acute inpatient rehabilitation in the hospital setting is feasible and may reduce both readmission rates and disability.

Development and Implementation of a Standard Assessment Battery Across the Continuum of Care for Patients After Stroke.

ABSTRACT: Stroke rehabilitation occurs across the continuum of care starting in the acute hospital and through the inpatient and outpatient settings. Rehabilitation aims to minimize impairments and maximize function in individuals after stroke. Because patients often undergo rehabilitation for extended periods, longitudinal assessment of impairment, activity, and participation can facilitate the evaluation of patients' progress toward recovery, as well as communication and decision making to guide clinical practice regarding the intervention(s) to be used and may also be leveraged for clinical research. However, the clinical implementation of a standard assessment battery that spans the continuum of care for patients after stroke is challenging because of operational and time constraints. Here, we describe the development and implementation of a standard assessment battery across the continuum of care by physical therapists, occupational therapists, and speech-language pathologists at the Sheikh Khalifa Stroke Institute. We specifically describe our experience in (1) identifying the core team to lead the process, (2) selecting the measures for the standard assessment battery, and the timeframe for administration, and (3) implementing the standard assessment battery in routine clinical practice.

Clinical Implementation of Noninvasive Brain Stimulation in an Outpatient Neurorehabilitation Program.

ABSTRACT: Motor, speech, and cognitive impairments are the most common consequences of neurological disorders. There has been an increasing interest in the use of noninvasive brain stimulation techniques such as transcranial direct current stimulation and transcranial magnetic stimulation to augment the effects of neurorehabilitation. Numerous research studies have shown that transcranial direct current stimulation and transcranial magnetic stimulation are highly promising neuromodulation tools that can work as adjuvants to standard neurorehabilitation services, including physical therapy, occupational therapy, and speech-language pathology. However, to date, there are vast differences in methodology in studies including noninvasive brain stimulation parameters, patient characteristics, time point of intervention after injury, and outcome measures, making it difficult to translate and implement transcranial direct current stimulation and transcranial magnetic stimulation in the clinical setting. Despite this, a series of principles are thought to underlie the effectiveness of noninvasive brain stimulation techniques. We developed a noninvasive brain stimulation rehabilitation program using these principles to provide best practices for applying transcranial direct current stimulation and/or transcranial magnetic stimulation as rehabilitation adjuvants in the clinical setting to help improve neurorehabilitation outcomes. This article outlines our approach, philosophy, and experience.

Implementation of a Framework for Telerehabilitation in Clinical Care Across the Continuum During COVID-19 and Beyond.

ABSTRACT: The COVID-19 pandemic has propelled an unprecedented global implementation of telemedicine and telerehabilitation as well as its integration into the healthcare system. Here, we describe the clinical implementation of the A3E framework for the deployment of telerehabilitation in the inpatient and outpatient rehabilitation continuum by addressing accessibility, adaptability, accountability, and engagement during the COVID-19 pandemic. By using an organized, coordinated, and stratified approach, we increased our telerehabilitation practice from 0 to more than 39,000 visits since the pandemic began. Learning from both the successes and challenges can help address the need to increase access to rehabilitation services even beyond the COVID-19 pandemic.

Temporal evolution of oscillatory activity predicts performance in a choice-reaction time reaching task.

In this study, we characterized the patterns and timing of cortical activation of visually guided movements in a task with critical temporal demands. In particular, we investigated the neural correlates of motor planning and on-line adjustments of reaching movements in a choice-reaction time task. High-density electroencephalography (EEG, 256 electrodes) was recorded in 13 subjects performing reaching movements. The topography of the movement-related spectral perturbation was established across five 250-ms temporal windows (from prestimulus to postmovement) and five frequency bands (from theta to beta). Nine regions of interest were then identified on the scalp, and their activity was correlated with specific behavioral outcomes reflecting motor planning and on-line adjustments. Phase coherence analysis was performed between selected sites. We found that motor planning and on-line adjustments share similar topography in a fronto-parietal network, involving mostly low frequency bands. In addition, activities in the high and low frequency ranges have differential function in the modulation of attention with the former reflecting the prestimulus, top-down processes needed to promote timely responses, and the latter the planning and control of sensory-motor processes.

Acquisition and retention of motor sequences: the effects of time of the day and sleep.

STUDY OBJECTIVES: We used a sequence-learning task to assess whether: 1. The time interval between awakening and training equally affects the rate of acquisition of sequence order, a declarative component, and the kinematic optimization process, an implicit component; 2. Sleep enhances the retention of both these aspects of sequence learning. DESIGN: For aim 1, we compare the acquisition rate of a new motor sequence in a group trained in the morning and another in the evening. For aim 2., we tested retention of the same motor sequence twelve hours later, either without sleep (normal day activity or a night of sleep deprivation) or with interposed sleep (afternoon napping or regular full night sleep). SETTING: Training and Testing were performed in a controlled laboratory setting. PARTICIPANTS: Thirty-six right-handed normal subjects (age range 18-24 years; 16 women). RESULTS: During the training, acquisition rate of the sequence order was significantly higher in the AM-trained than in the PM-trained group, without differences in the kinematic optimization processes. Both declarative and implicit learning indices were significantly higher in the subjects tested after sleep compared to those tested without interposed sleep. CONCLUSION: The best time for fast and efficient acquisition of new declarative material is the morning, while the kinematic aspects of skill acquisition are not sensitive to the time of day. However, better retention of both declarative material and motor skills requires two conditions: a period of post-training sleep and the achievement of performance saturation during training.

Comparison between 3-Nitrooxyphenyl acetylsalicylate (NO-ASA) and O2-(acetylsalicyloxymethyl)-1-(pyrrolidin-1-yl)diazen-1-ium-1,2-diolate (NONO-ASA) as safe anti-inflammatory, analgesic, antipyretic, antioxidant prodrugs.

Chronic inflammation is an underlying etiological factor in carcinogenesis; nonsteroidal anti-inflammatory drugs (NSAIDs) and their chemically modified NO-releasing prodrugs (NO-NSAIDs) are promising chemopreventive agents. The aim of this study was to conduct a head-to-head comparison between two NO-ASAs possessing different NO donor groups, an organic nitrate [3-nitrooxyphenyl acetylsalicylate (NO-ASA; NCX-4016)] and an N-diazeniumdiolate [NONO-ASA, O(2)- (acetylsalicyloxymethyl)-1-(pyrrolidin-1-yl)diazen-1-ium-1,2-diolate (NONO-ASA; CVM-01)], as antiulcerogenic, analgesic, anti-inflammatory, and antipyretic agents. All drugs were administered orally at equimolar doses. For antiulcerogenic study, 6 h after administration, the number and size of hemorrhagic lesions in stomachs from euthanized animals were counted. Tissue samples were frozen for prostaglandin E(2) (PGE(2)), superoxide dismutase (SOD), and malondialdehyde determination. For anti-inflammatory study, 1 h after drug administration, the volume of carrageenan-induced rat paw edemas was measured for 6 h. For antipyretic study, 1 h after dosing, fever was induced by intraperitoneal LPS, and body core temperatures measured for 5 h. For analgesic study, time-dependent analgesic effect of prodrugs was evaluated by carrageenan-induced hyperalgesia. Drugs were administered 30 min after carrageenan. NO-ASA and NONO-ASA were equipotent as analgesic and anti-inflammatory agents but were better than aspirin. Despite a drastic reduction of PGE(2) in stomach tissue, both prodrugs were devoid of gastric side effects. Lipid peroxidation induced by aspirin was higher than that observed by prodrugs. SOD activity induced by both prodrugs was similar, but approximately 2-fold higher than that induced by aspirin. CVM-01 is as effective as NCX-4016 in anti-inflammatory, analgesic, and antipyretic assays in vivo, and it showed an equivalent safety profile in the stomach. These results underscore the use of N-diazeniumdiolate moieties in drug design.
