Abstract WP430: Implementation of Inpatient Stroke Champions Leads to Improved Inpatient Code Stroke Metrics

Introduction: Stroke Champions (SC) are AHA recommended designated inpatient nurses that serve as expert resources for their units to ensure that evidence-based practices for stroke care are implemented. Inpatient Code Strokes (ICS) are difficult to recognize which results in delayed treatment. The purpose of this study is to determine if there was an improvement in inpatient acute stroke metrics with the addition of SC in the hospital. Methods: Over a 12-month period at a Comprehensive Stroke Center (CSC), 12 nurses in the inpatient stroke units were trained as SC. This training consisted of advanced education in CSC metrics, guidelines and required documentation. SC provided peer-to-peer education, served as expert resources, conducted comprehensive chart reviews, shift huddles, and “on the spot” feedback to nurses and physicians. The metrics were examined pre and post intervention and included: Symptom Recognition Time (SRT) to CT interpretation, SRT to tPA bolus time, and SRT to groin puncture. SRT is equivalent to Emergency Department door time for inpatient strokes. Statistical analysis was performed using T-test and the Mann-Whitney test. Results: There were 114 pre-SC and 101 post-SC ICS. There was a trend toward more patients being accurately diagnosed with a TIA or stroke (75.3% post vs. 65.8% pre-SC; p=0.06). The SRT to CT interpretation time for patients who received tPA improved from 43 to 35 mins. The number of patients treated with tPA increased from 10 to 17. SRT to tPA bolus time trended toward improvement from 57 to 42 mins (p=0.07). SRT to groin puncture time in patients who received both tPA and thrombectomy trended toward improvement from 81 vs. 65 mins (p=0.07). There were twice as many inpatient thrombectomy cases in post-SC (n=23) vs. pre-SC (n=12). Conclusion: The knowledge and expertise provided by SC resulted in a higher percentage of ICS having a final diagnosis of stroke. This demonstrates an increased accuracy of stroke specific symptom recognition by the inpatient nursing teams. There was improved SRT to tPA bolus and groin puncture time. This is the only study that shows implementation of the AHA recommended SC program improves inpatient code stroke recognition and treatment metrics.

The Impact

Introduction. Many reports have described a decrease in the numbers of patients seeking medical attention for typical emergencies during the COVID-19 pandemic. These reports primarily relate to urban areas with widespread community transmission. The impact of COVID-19 on nonurban areas with minimal community transmission is less well understood. Methods. Using a prospectively maintained prehospital quality improvement database, we reviewed our hospital EMS transports with a diagnosis of stroke from January to April 2019 (baseline) and January to April 2020 (pandemic). We compared the volume of patients, transport/presentation times, severity of presenting symptoms, and final diagnosis. Results. In January, February, March, and April 2019, 10, 11, 17, and 19 patients, respectively, were transported in comparison to 19, 14, 10, and 8 during the same months in 2020. From January through April 2019, there was a 53% increase in transports, compared to a 42% decrease during the same months in 2020, constituting significantly different trend-line slopes (3.30; 95% CI 0.48–6.12 versus -3.70; 95% CI -5.76–-1.64, p = 0.001 ). Patient demographics, comorbidities, and symptom severity were mostly similar over the two time periods, and the number of patients with a final diagnosis of stroke was also similar. However, the median interval from EMS dispatch to ED arrival for patients with a final diagnosis of stroke was significantly longer in January to April 2020 ( 50 ± 11.7 min ) compared to the same time period in 2019 ( 42 ± 8.2 min , p = 0.01 ). Discussion/Conclusion. Our data indicate a decrease in patient transport volumes and longer intervals to EMS activation for suspected stroke care. These results suggest that even in a nonurban location without widespread community transmission, patients may be delaying or avoiding care for severe illnesses such as stroke. Clinicians and public health officials should not ignore the potential impact of pandemic-like illnesses even in areas of relatively low disease prevalence.

Introduction: The Joint Commission has established time sensitive metrics for stroke care in the Emergency Department (ED) including door to initial physician evaluation, door to lab and CT order placement, door to lab resulted and door to CT interpretation. Purpose: The purpose of this quality improvement project was to assess if nurse entered protocolized order sets for stroke patients would help to improve these metrics. Methods: A code stroke order set was initiated independently by nursing staff upon symptom recognition in the ED. The order set included CBC, electrolyte panel, BUN, creatinine, glucose, troponin, PT/INR, aPTT, non-contrast CT head, EKG, swallow screen and continuous cardiac monitoring. Data was collected for 3 months pre and post intervention. All ED nurses were trained on order set entry and their skills were validated. Data was analyzed using a T-Test. Results: 60 patient pre and 52 post-implementation were evaluated. Door to initial physician evaluation was faster (7 mins pre vs. 5 mins post; p=0.029). Door to lab order placement was faster (8 mins pre vs. 3 mins post; p=0.038). Door to CT ordered was faster (8 mins pre vs. 6 mins post; p<0.01). Door to labs resulted was faster (32 mins pre vs. 27 mins post; p=0.01). Door to CT interpretation was faster (19 mins pre vs. 18 mins post; p=0.04). Conclusion: Implementation of nurse entered order sets can improve ED metrics for door to initial physician evaluation, door to lab and CT order placement. This subsequently led to faster interpretation of the CT scan and lab results.

Introduction: Although Mobile Stroke Treatment Units (MSTU) can reduce time to intravenous thrombolysis (IVtPA), limitations in MSTU care have not been well described. Methods: We retrospectively reviewed consecutive patients transported by MSTU to our academic comprehensive stroke center (CSC) from May 2019 to August 2020 for suspected stroke to assess for potential limitations of care. The Columbus MSTU is owned by a separate health system, but represents a collaborative venture with 3 CSCs and the Columbus Division of Fire, operating daily from 7am-7pm. Data was abstracted on demographics, clinical presentation, last known normal (LKN) time, initial National Institutes of Health Stroke Scale (NIHSS), neuroimaging, and IVtPA administration. Results: Among 93 patients transported to our CSC by MSTU, the mean age was 65 years (range, 21-93) and 61 (66%) were female. The mean initial NIHSS was 7.1 (range, 0 to 33) and 52 (55.9%) had a final diagnosis of stroke (4 hemorrhagic, 48 ischemic). IVtPA was administered in 15 (16.1%) with a mean LKN to IVtPA time of 120 minutes (range, 41 to 243). Among 15 patients treated with IVtPA, 10 received IVtPA in MSTU and 5 in CSC ED. In 7 patients who underwent thrombectomy, mean door to groin time was 57 minutes (range, 28 to 88). Among the overall group, 9 (9.7%) cases were identified with limitations in MSTU care, including 2 patients who received IVtPA by MSTU that were more than 10% off from ideal dosing (underdosed by 9mg and overdosed by 21mg), 1 warfarin-associated hemorrhage requiring intubation who did not receive reversal in MSTU but did upon arrival to CSC ED, and 5 patients who received IVtPA after arrival to CSC ED. The reasons for withholding IVtPA included inability to confirm LKN, patient declination, lack of translator, incorrect LKN, and seizure requiring intubation. The LKN to IVtPA time was significantly longer in the ED compared to MSTU (197 vs 82 minutes, p <0.0001). Conclusion: In our series of suspected stroke patients evaluated by MSTU, gaps identified within MSTU acute stroke care were related to limitations of resources and included errors in weight-based IVtPA dosing, inability to administer IVtPA, or reversal for anti-coagulation related hemorrhage. Clinicians need to be aware of potential pitfalls of MSTU evaluation.

The slopes of these trend lines are significantly different (3.30; 95%CI 0.48 - 6.12 versus -3.70; 95%CI -5.76 - -1.64, P = 0.001). There were no significant differences in demographics, comorbidities, symptom severity, or stroke discharge diagnoses between the two time periods. However, the median interval from LKW to time of EMS dispatch was significantly longer in January to April 2020 (12 + 273 min) compared to the same time period of January through April in 2019 (7 + 115 min). Conclusion: Our data indicate not only a decrease in patient transport volumes but more alarmingly, significantly longer intervals to EMS activation for suspected stroke care. These results suggest that even in a non-urban location without widespread community transmission patients were delaying or avoiding care for severe illness such as stroke.

Abstract Background Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, the stroke care systems have been seriously affected because of social restrictions and other reasons. As the pandemic continues to spread globally, it is of great significance to understand how COVID-19 affects the stroke care systems in mainland China. Methods We retrospectively studied the real-world data of one comprehensive stroke center in mainland China from January to February 2020 and compared it with the data collected during the same period in 2019. We analyzed DTN time, onset-to-door time, severity, effects after treatment, the hospital length of stays, costs of hospitalization, etc., and the correlation between medical burden and prognosis of acute ischemic stroke (AIS) patients. Results The COVID-19 pandemic was most severe in mainland China in January and February 2020. During the pandemic, there were no differences in pre-hospital or in-hospital workflow metrics (all p>0.05), while the degree of neurological deficit on admission and at discharge, the effects after treatment, and the long-term prognosis were all worse (all p<0.05). The severity and prognosis of AIS patients were positively correlated with the hospital length of stays and total costs of hospitalization (all p<0.05). Conclusions COVID-19 pandemic is threatening the stroke care systems. Measures must be taken to minimize the collateral damage caused by COVID-19.

BackgroundCurrent efforts to reduce door to groin puncture time (DGPT) aim to optimize clinical outcomes in stroke patients with large vessel occlusions (LVOs). The RapidAI mobile application (Rapid Mobile App) provides quick access to perfusion and vessel imaging in patients with LVOs. We hypothesize that utilization of RapidAI mobile application can significantly reduce treatment times in stroke care by accelerating the process of mobilizing stroke clinicians and interventionalists.MethodsWe analyzed patients presenting with LVOs between June 2019 and October 2020. Thirty-one patients were treated between June 2019 and March 2020 (pre-app group). Thirty-three patients presented between March 2020 and October 2020 (post-app group). Mann–Whitney U test and Kruskal–Wallis tests were used to examine variables that are not normally distributed. In a secondary analysis we analyzed interhospital time metrics between primary stroke centers and our comprehensive stroke center.ResultsBaseline demographic and vascular risk factors were similar in both groups. Use of Rapid Mobile App resulted in 33 min reduction in DGPT (P=0.02), 35 min reduction in door to first pass time (P=0.02), and 37 min reduction in door to recanalization time (P=0.02) in univariate analyses when compared with patients treated pre-app. In a multiple linear regression model, utilization of Rapid Mobile App significantly predicted shorter DGPT (P=0.002). In an adjusted model, National Institutes of Health Stroke Scale (NIHSS) 24 hours after procedure and at discharge were significantly lower in the post-app group (P=0.03). Time of transfer between primary and comprehensive stroke center was comparable in both groups (P=0.26).ConclusionIn patients with LVOs, the implementation of the RapidAI mobile application was independently associated with reductions in intrahospital treatment times.

Background: “Drip-and-ship” denotes patients in whom intravenous (IV) recombinant tissue plasminogen activator (rt-PA) is initiated at the emergency department (ED) of a community hospital, followed by transfer within 24 hours to a comprehensive stroke center. Although drip-and-ship paradigm has the potential to increase the number of patients who receive IV rt-PA, comparative outcomes have not been assessed at a population based level. Methods: State-wide estimates of thrombolysis, associated in-hospital outcomes and mortality were obtained from 2008-2009 Minnesota Hospital Association (MHA) data. Patient numbers and frequency distributions were calculated for state-wide sample of patients hospitalized with a primary diagnosis of ischemic stroke. Patients outcomes were analyzed after stratification into patients treated with IV rt-PA through primary ED arrival or drip-and-ship paradigm. Results: Of the 21,024 admissions, 602 (2.86%) received IV rt-PA either through primary ED arrival (n=473) or drip-and-ship paradigm (n=129). The rates of secondary intracerebral or subarachnoid hemorrhage were higher in patients treated with IV rt-PA through primary ED arrival compared with those treated with drip-and-ship paradigm (8.5% versus 3.1, p=0.038). The in-hospital mortality rate was similar among ischemic stroke patients receiving IV rt-PA through primary ED arrival or drip-and-ship paradigm (5.9% versus 7.0%). The mean hospital charges were $65,669 for primary ED arrival and $47,850 for drip-and-ship treated patients (p<0.001). Conclusions: The results of drip-and-ship paradigm compare favorably with IV rt-PA treatment through primary ED arrival in this state-wide study.

Positive Effect

Introduction: Treatment time has gained sufficient popularity because it is now well-known that “Time is Brain”. Treatment rates, however, lag behind in importance even though more lives can be saved by treating more often. Our TJC Comprehensive Stroke Center has a nurse-led stroke alert process that focuses on multiple, rapid, parallel steps to reduce DTN for IV alteplase. The Baptist Emergency Stroke Team (BEST) responders are highly-trained and skilled nurses that assess, coordinate, and initiate processes to ensure the best times. We identified that our treatment rate was lower than the national rate for certified CSCs, so the BEST responders used a stepwise process to develop their own interventions to improve rates. Methods: First, the BEST responders started tracking our monthly rate. Next, they set a rate goal, and then brainstormed how to influence treatment decision-making. The BEST team initiated a monthly PI meeting that focused on the importance of treating disability rather than an NIHSS score. Then the team scripted and rehearsed critical conversations to have providers that advocated specifically for treating disability. The team adopted the motto, “Treat Disability, Not Numbers”. Results Conclusions: Our CSC observed a small decrease in median DTN but double the treatment rate after the BEST responder intervention. In comparison, these statistics did not change at the national CSC level. The sICH rate was reduced from Period A to C, meaning that increased treatment rate did not lead to increased hemorrhagic rate. Nursing initiatives can have a substantial positive effect on increasing the number of patients treated with IV alteplase for acute ischemic stroke.

Good Diagnostic Accuracy

A reliable and fast instrument for prehospital detection of large vessel occlusion (LVO) stroke would be a game-changer in stroke care, because it would enable direct transportation of LVO stroke patients to the nearest comprehensive stroke center for endovascular treatment. This strategy would substantially improve treatment times and thus clinical outcomes of patients. Here, we outline our view on the requirements of an effective prehospital LVO detection method, namely: high diagnostic accuracy; fast application and interpretation; user-friendliness; compactness; and low costs. We argue that existing methods for prehospital LVO detection, including clinical scales, mobile stroke units and transcranial Doppler, do not fulfill all criteria, hindering broad implementation of these methods. Instead, electroencephalography may be suitable for prehospital LVO detection since in-hospital studies have shown that quantification of hypoxia-induced changes in the electroencephalography signal have good diagnostic accuracy for LVO stroke. Although performing electroencephalography measurements in the prehospital setting comes with challenges, solutions for fast and simple application of this method are available. Currently, the feasibility and diagnostic accuracy of electroencephalography in the prehospital setting are being investigated in clinical trials.

The Joint Commission

Background: The Joint Commission (TJC) Comprehensive Stroke Center standard requires monitoring of patients after IV tPA administration, diagnostic angiography, aneurysm coiling, carotid angioplasty and stenting, mechanical endovascular reperfusion (MER) and carotid endarterectomy. Meeting 100% compliance of the standard is challenging. In 2018, monitoring and documentation were among the TJC’s top ten cited survey findings. Purpose: To determine if an electronic tool can improve documentation compliance and reduce delays in monitoring of vital signs, and neurologic, pedal pulse and skin site assessments. Methods: The initiative was implemented in 2018 with the objective for all patients to have 100% of their post procedural monitoring completed. A documentation tool was created and introduced to nursing units via annual stroke education updates. The tool was added to an online nursing resource SharePoint website and application, which was accessible to all nurses within the hospital. The procedure end time was entered in the tool, which automatically calculated the documentation times. Data was compared 12 months pre and post intervention. Analysis and reporting of data were conducted monthly via the program’s quality oversight committee. Data was analyzed using T-Test. Results: In post-IV tPA patients, more patients had 100% complete documentation (79% post vs. 29% pre-implementation; p=0.006). For all post neuro-interventional radiology procedures, more patients had 100% complete documentation (68% post vs. 17% pre-implementation; p<0.001). For post carotid endarterectomy revascularization, there was a trend toward more patients with 100% complete documentation (83% vs 38%; p=0.07). Conclusion: Utilization of an electronic monitoring tool for post procedural documentation adherence can improve the percentage of patients who have 100% completed assessments and help meet the TJC standard.
