Objective: To assess the feasibility and potential scalability of telemedicine-enabled ambulances for the prehospital evaluation of patients with suspected acute stroke symptoms. Patients and Methods: A pilot study of telemedicine-enabled ambulances for evaluating patients with suspected acute stroke symptoms en route at 2 tertiary academic comprehensive stroke centers from January 1, 2018, to February 5, 2024. Charts of included patients were reviewed for demographic data, vascular risk factors, final diagnosis, time from arrival to neuroimaging, door-to–needle and door-to-puncture times in patients eligible for acute treatment, and any reported technical challenges during audio-video consultations. Results: Forty-seven patients (mean age, 68.0 years; 62% men) were evaluated via telemedicine-enabled ambulances, of which 35 (74%) where for hospital-to-hospital transferred patients. Mean time from arrival to neuroimaging was 11.8 minutes. Twenty-nine patients (62%) were diagnosed with acute ischemic stroke, and the remainder were diagnosed with intracranial hemorrhage (n=13), seizure (n=2), brain mass (n=1), or other diagnoses (n=3). Four patients (9%) received intravenous thrombolysis with alteplase (mean door to needle, 30.3 minutes), and 15 patients (32%) underwent mechanical thrombectomy (mean door to puncture, 72 minutes). Technical challenges were reported in 15 of the 42 (36%) cases, of which 10 (67%) were related to poor internet connectivity. Conclusion: Telemedicine-enabled ambulances in emergency medical services systems are novel, feasible, and potentially scalable options for evaluating patients with suspected acute stroke in the prehospital setting. However, optimization of infrastructure, staffing models, and internet connectivity is necessary, and larger studies evaluating the clinical and cost effectiveness of this approach are needed before widespread implementation.

Objective: To describe the safety and feasibility of a fast-track pathway for neurosurgical craniotomy patients receiving care in a neurosciences progressive care unit (NPCU). Patients and Methods: Traditionally, most craniotomy patients are admitted to the neurosciences intensive care unit (NSICU) for postoperative follow-up. Decreased availability of NSICU beds during the coronavirus disease-2019 delta surge led our team to establish a de-novo NPCU to preserve capacity for patients requiring high level of care and would bypass routine NSICU admissions. Patients were selected a priori by treating neurosurgeons on the basis of the potential need for high-level ICU services. After operation, selected patients were transferred to the postoperative care unit, where suitability for NPCU transfer was reassessed with checklist-criteria. This process was continued after the delta surge. Results: From July 1, 2021 to September 30, 2022, 57 patients followed the NPCU protocol. Thirty-four (59.6%) were women, and the mean age was 56 years. Fifty-seven craniotomies for 34 intra-axial and 23 extra-axial lesions were performed. After assessment and application of the checklist-criteria, 55 (96.5%) were transferred to NPCU, and only 2 (3.5%) were transferred to ICU. All 55 patients followed in NPCU had good safety outcomes without requiring NSICU transfer. This saved $143,000 and led to 55 additional ICU beds for emergent admissions. Conclusion: This fast-track craniotomy protocol provides early experience that a surgeon-selected group of patients may be suitably monitored outside the traditional NSICU. This system has the potential to reduce overall health care expenses, increase capacity for NSICU bed availability, and change the paradigm of NSICU admission.

Medical-grade ultrasound devices are now pocket sized and can be easily transported to underserved parts of the world, allowing health care providers to have the tools to optimize diagnoses, inform management plans, and improve patient outcomes in remote locations. Other great advances in technology have recently occurred, such as artificial intelligence applied to mobile health devices and cloud computing, as augmented reality instructions make these devices more user friendly and readily applicable across health care encounters. However, broader awareness of the impact of these mobile health technologies is needed among health care providers, along with training on how to use them in valid and reproducible environments, for accurate diagnosis and treatment. This article provides a summary of a Mayo International Health Program journey to Bwindi, Uganda, with a portable mobile health unit. This article shows how point-of-care ultrasonography and other technologies can benefit remote clinical diagnosis and management in underserved areas around the world.

Objective: To describe telemedicine utilization in neurosurgery at a single tertiary institution to provide outpatient care during the coronavirus disease 2019 (COVID-19) pandemic, with 315 telemedicine visits performed by the neurosurgery department. Patients and Methods: In response to the COVID-19 pandemic national stay-at-home orders and postponed elective surgeries, we converted upcoming clinic visits into telemedicine visits and rescheduled other patients thought not to be markedly affected by surgical postponement. We reviewed the charts of all patients who had telehealth visits from April 1 through April 30, 2020, and collected demographic information, diagnosis, type of visit, and whether they received surgery; a satisfaction questionnaire was also administered. Results: In March 2020, 94% (644 of 685) of the neurosurgery clinic visits were face-to-face, whereas in April 2020, 55% (315 of 573) of the visits were telemedicine (P

Objective: To determine whether earlier hospital discharge is feasible and safe in selected patients with subarachnoid hemorrhage (SAH) using an outpatient “fast-track” protocol. Patients and Methods: We conducted a prospective quality improvement cohort study with the primary feasibility end point of patients with SAH deemed safe for discharge by treating team consensus. All patients received detailed education and outpatient transcranial Doppler monitoring; caregivers could contact the on-call team 24-7. Primary safety end points were adverse events after discharge and hospital readmission. Results: From January 1, 2010, to January 1, 2015, our center had 377 SAH diagnoses, of which 200 were included in the final cohort, 36 qualifying for fast-track early discharge. The 30-day readmission rate for fast-track patients was 11.0% (4 of 36) compared with 11.4% (18 of 164) for non–fast-track patients. The rate of delayed cerebral ischemia and stroke was 3% (1 of 36) in the fast-track group vs 25.0% (41 of 164) for the non–fast-track group. Adverse events occurred in 11.0% (4 of 36) of the fast-track group compared with 26.0% (43 of 164) in the non–fast-track group. The mean length of stay was reduced 60% from 15 days to 6.6 days in the fast-track group. Conclusion: Although our fast-track group was relatively small, data suggested early feasibility and safety in a carefully selected group of patients with SAH. Direct and indirect financial benefits of early discharge over a 5-year period were an estimated savings at least $864,000 in overall costs. A comparative effectiveness study is planned to replicate and validate these results using a larger multicenter design.

Objective: To reduce door-to-angiographic reperfusion (DTR) time to 120 minutes for patients presenting with acute ischemic stroke attributed to anterior circulation large-vessel occlusion amenable to endovascular mechanical thrombectomy. Patients and Methods: Patients treated with mechanical thrombectomy before (April 10, 2015, through April 11, 2016) and after (April 12, 2016, through May 10, 2017) implementation of a multitiered notification system were studied. Lean process mapping was used to assess inefficiencies with multidisciplinary triage. A 3-tiered paging platform, which rapidly alerts essential personnel of the acute ischemic stroke team at advancing decision points, was introduced. Results: Sixty-two patients were analyzed before and after implementation (34 vs 28, respectively). Following intervention, DTR time was reduced by 43 minutes (mean DTR, 170 minutes vs 127 minutes; P=.02). At 90-day follow up, 5 of the 28 patients in the postintervention cohort (19%) had excellent neurologic outcomes, defined as a modified Rankin Scale score of 0, compared to 0 of 34 (0%) in the preintervention cohort (P=.89). Reductions were also seen in the length of stay on the neurocritical care service (mean, 6 vs 3 days; P=.006), and total hospital charges for combined groups (mean, $100,083 vs $161,458; P

Objective: Hourly neurological examinations are frequently performed in the neurointensive care unit (NICU) to quickly detect neurological deterioration. These examinations require the patient to be awakened hourly for days disrupting the sleep cycle and potentially causing neurological deterioration through sleep deprivation and the development of delirium. This pilot study's aim was to describe the prevalence of neurologic deterioration and delirium in patients receiving hourly neuro checks., Design: A 6-month prospective observational cohort study was conducted within the NICU at Mayo Clinic Florida. Twenty subjects were enrolled between July 24, 2016, and January 30, 2017., Results: Neurological deterioration as defined as a decrease in Glasgow Coma Scale score of 2 or more, an increase in National Institute of Health Stroke Scale score by 4 or more, or a change in Confusion Assessment Method score for use in intensive care unit patients from negative to positive occurred in 19 of 20 patients (95%) for a total of 67 events, with most patients having multiple events. Seventy-five percent of the subjects experienced a decrease in Glasgow Coma Scale score of 2 or more at least once during the study period. The largest number of events occurred within the first 24 hours (39%). Surprisingly, 75% of the subjects also developed delirium. Forty percent of the subjects demonstrating neurological deterioration received computed tomography imaging to evaluate the change. Sixty-seven percent lacked deterioration evident on computed tomography imaging, and the deterioration was not attributed to medication effect or seizure by an experienced provider., Conclusions: Neurological deterioration is prevalent in the NICU population. Although hourly neurological examinations may be beneficial in the acute phase of neurological injury, prolonged use may be paradoxically harmful due to sleep deprivation.

Introduction: We hypothesized that a nocturnist advanced practice provider (APP) model compared with overnight neurocritical care coverage with general critical care physicians and neurology residents would provide similar patient outcomes, as measured by patient mortality., Methods: This study is a retrospective review of healthcare outcomes of aneurysmal subarachnoid hemorrhage (aSAH) patients from 2013 and 2016, after implementation of specialty-trained neurocritical care nocturnist APPs. In 2013, overnight hours were covered by the general intensive care unit team and a junior neurology resident. In 2016, these patients were cared for by APPs overnight. The primary outcome measured was comparison of mortality before and after this change of overnight coverage because the daytime coverage remained similar between years., Results: In 2013, 58 patients were admitted to the neurocritical care unit with aSAH. In 2016, 19 aSAH patients were admitted to the neurocritical care unit. The mean modified Fisher grade was 3.36 in 2013, with 14 of 58 deaths (mortality rate, 24%). In 2016, the mean modified Fisher grade was 3.4. Three patients died (mortality rate, 15.7%)., Conclusion: The active nocturnist APP model was associated with an approximately 10% reduction in SAH mortality (P = .54). This supports the hypothesis that APPs can provide noninferior care as the previous model. Further studies are needed to demonstrate the effects of both nocturnist and APP-driven models.

Introduction: It was observed that women with aneurysmal subarachnoid hemorrhage (aSAH) tended to have earlier menses than a typical 21- to 28-day cycle. The goal was to determine whether there is an association between aSAH and early onset of menses., Methods: All cases of aSAH in women aged 18 to 55 years who were admitted to our facility's neuroscience intensive care unit from June 1, 2011, to June 30, 2012, were reviewed. The electronic healthcare record for each of these patients was examined for documentation of menses onset, computed tomography of the head, brain aneurysm characteristics, modified Fisher score and Glasgow Coma Scale on admission, presence/absence of vasospasm, medical/surgical history, and use of medications that affect the menstrual cycle. The mean onset of menses in this study population was compared with the mean of 21 to 28 days with the 1-sample t test., Results: During the study period, 103 patients with subarachnoid hemorrhage were admitted. Sixty-one were women, and 15 were aged 18 to 55 years. Nine of the 15 (60%) had documentation of menses occurring during their initial week of hospitalization; 1 patient had documentation of menses on hospital day 12. There is a significant difference when the mean onset of menses in our patient population is compared with the approximate normal menstrual cycle of 21 to 28 days (P < .01)., Conclusion: Early onset of menses or abnormal uterine bleeding after SAH may occur in women with aSAH and typically within the first 7 to 10 days after intracranial aneurysm rupture. The physiologic cause of early onset of menses after aSAH, whether primary or secondary, remains unknown.
