Cost-Effectiveness of Intra-Arterial Treatment as an Adjunct to Intravenous Tissue-Type Plasminogen Activator for Acute Ischemic Stroke.

BACKGROUND AND PURPOSE: The objective of this study was to determine the cost-effectiveness of intra-arterial treatment within the 0- to 6-hour window after intravenous tissue-type plasminogen activator within 0- to 4.5-hour compared with intravenous tissue-type plasminogen activator alone, in the US setting and from a social perspective. METHODS: A decision analytic model estimated the lifetime costs and outcomes associated with the additional benefit of intra-arterial therapy compared with standard treatment with intravenous tissue-type plasminogen activator alone. Model inputs were obtained from published literature, the Multicenter Randomized Clinical Trial of Endovascular Therapy for Acute Ischemic Stroke in the Netherlands (MR CLEAN) study, and claims databases in the United States. Health outcomes were measured in quality-adjusted life years (QALYs). Treatment benefit was assessed by calculating the cost per QALY gained. One-way and probabilistic sensitivity analyses were performed to estimate the overall uncertainty of model results. RESULTS: The addition of intra-arterial therapy compared with standard treatment alone yielded a lifetime gain of 0.7 QALY for an additional cost of $9911, which resulted in a cost of $14 137 per QALY. Multivariable sensitivity analysis predicted cost-effectiveness (≤$50 000 per QALY) in 97.6% of simulation runs. CONCLUSIONS: Intra-arterial treatment after intravenous tissue-type plasminogen activator for patients with anterior circulation strokes within the 6-hour window is likely cost-effective. From a societal perspective, increased investment in access to intra-arterial treatment for acute stroke may be justified.

Clinical Decision Support for Patients Presenting With Large Vessel Occlusion.

A single center had a collaborative, multidisciplinary review to determine how to best implement new acute ischemic stroke trials involving large vessel occlusions. A flow diagram process map was created for clinical decision support. Patients were divided into four groups based upon size of infarct and timing of presentation. The process map, available in the electronic health record (EHR) for clinicians to reference, guides the selection of patients for endovascular therapy with neuroimaging. In addition, the process map offers guidance for discussions with families and patients experiencing large vessel occlusions with both small and large core infarcts. This manuscript describes the process of creating the process map through a multidisciplinary review and discussion, with points of controversy and how these were addressed.

Improving Seizure Frequency Documentation and Classification.

Background and Objectives: Accurate and reliable seizure data are essential for evaluating treatment strategies and tracking the quality of care in epilepsy clinics. This quality improvement project aimed to increase seizure documentation (i.e., documentation of seizure frequency from 80% to 100%, date of last seizure from 35% to 50%, and International League Against Epilepsy (ILAE) seizure classification from 35% to at least 50%) over 6 months. Methods: We surveyed 7 epileptologists to determine their perceived seizure frequency, ILAE classification, and date of last seizure documentation habits. Baseline data were collected weekly from September to December 2021. Subsequently, we implemented a newly created flowsheet in our Electronic Health Record (EHR) based on the Epilepsy Learning Healthcare System (ELHS) Case Report Forms to increase seizure documentation in a standardized way. Two epileptologists tested this flowsheet tool in their epilepsy clinics between February 2022 and July 2022. Data were collected weekly and compared with documentation from other epileptologists within the same group. Results: Epileptologists at our center believed they documented seizure frequency for 84%-87% of clinic visits, which aligned with baseline data collection, showing they recorded seizure frequency for 83% of clinic visits. Epileptologists believed they documented ILAE classification for 47%-52% of clinic visits, and baseline data showed this was documented in 33% of clinic visits. They also reported documenting the date of the last seizure for 52%-63% of clinic visits, but this occurred in only 35% of clinic visits. After implementing the new flowsheet, documentation increased to nearly 100% for all fields being completed by the providers who tested the flowsheet. Discussion: We demonstrated that by implementing an easy-to-use standardized EHR documentation tool, our documentation of critical metrics, as defined by the ELHS, improved dramatically. This shows that simple and practical interventions can substantially improve clinically meaningful documentation.

Matched-cohort analysis of autologous hematopoietic cell transplantation with radioimmunotherapy versus total body irradiation-based conditioning for poor-risk diffuse large cell lymphoma.

We conducted a matched-cohort analysis of autologous transplant conditioning regimens for diffuse large cell lymphoma in 92 patients treated with either radioimmunotherapy (RIT) or total body irradiation (TBI)-based conditioning regimens. The RIT regimen consisted of 0.4 mCi/kg of (90)Y-ibritumomab tiuxetan plus BEAM (BCNU, etoposide, cytarabine, melphalan). The TBI-based regimen combined fractionated TBI at 1200 cGy, with etoposide and cyclophosphamide. Five factors were matched between 46 patient pairs: age at transplant ±5 years, disease status at salvage, number of prior regimens, year of diagnosis ±5 years, and year of transplantation ±5 years. Patients in the TBI group had higher rates of cardiac toxicity and mucositis, whereas Z-BEAM patients had a higher incidence of pulmonary toxicity. Overall survival at 4 years was 81.0% for the Z-BEAM and 52.7% for the TBI group (P = .01). The 4-year cumulative incidence of relapse/progression was 40.4% and 42.1% for Z-BEAM and TBI, respectively (P = .63). Nonrelapse mortality was superior in the Z-BEAM group: 0% compared with 15.8% for TBI at 4 years (P < .01). Our data demonstrate that RIT-based conditioning had a similar relapse incidence to TBI, with lower toxicity, resulting in improved overall survival, particularly in patients with ≥2 prior regimens.

Optimizing the electronic health record: An inpatient sprint addresses provider burnout and improves electronic health record satisfaction.

OBJECTIVE: We sought reduce electronic health record (EHR) burden on inpatient clinicians with a 2-week EHR optimization sprint. MATERIALS AND METHODS: A team led by physician informaticists worked with 19 advanced practice providers (APPs) in 1 specialty unit. Over 2 weeks, the team delivered 21 EHR changes, and provided 39 one-on-one training sessions to APPs, with an average of 2.8 hours per provider. We measured Net Promoter Score, thriving metrics, and time spent in the EHR based on user log data. RESULTS: Of the 19 APPs, 18 completed 2 or more sessions. The EHR Net Promoter Score increased from 6 to 60 postsprint (1.0; 95% confidence interval, 0.3-1.8; P = .01). The NPS for the Sprint itself was 93, a very high rating. The 3-axis emotional thriving, emotional recovery, and emotional exhaustion metrics did not show a significant change. By user log data, time spent in the EHR did not show a significant decrease; however, 40% of the APPs responded that they spent less time in the EHR. CONCLUSIONS: This inpatient sprint improved satisfaction with the EHR.

Mexican Americans with atrial fibrillation have more recurrent strokes than do non-Hispanic whites.

BACKGROUND AND PURPOSE: Atrial fibrillation is a common cause of stroke with a known preventive treatment. We compared poststroke recurrence and survival in Mexican Americans (MAs) and non-Hispanic whites (NHWs) with atrial fibrillation in a population-based study. METHODS: Using surveillance methods from the Brain Attack Surveillance in Corpus Christi Project, cases of ischemic stroke/transient ischemic attack with atrial fibrillation were prospectively identified from January 2000 to June 2008. Recurrent stroke and all-cause mortality were compared by ethnicity with survival analysis methods. RESULTS: A total of 236 patients were available (88 MAs, 148 NHWs). MAs were younger than NHWs, with no ethnic differences in severity of the first stroke or proportion discharged on warfarin. MAs had a higher risk of stroke recurrence than did NHWs (Kaplan-Meier estimates of survival free of stroke recurrence risk at 28 days and 1 year were 0.99 and 0.85 in MAs and 0.98 and 0.96 in NHWs, respectively; P=0.01, log-rank test), which persisted despite adjustment for age and sex (hazard ratio=2.46; 95% CI, 1.19-5.11). Severity of the recurrent stroke was higher in MAs than in NHWs (P=0.02). There was no ethnic difference in survival after stroke in unadjusted analysis or after adjusting for demographic and clinical factors (hazard ratio=1.03; 95% CI, 0.63-1.67). CONCLUSIONS: MAs with atrial fibrillation have a higher stroke recurrence risk and more severe recurrences than do NHWs but no difference in all-cause mortality. Aggressive stroke prevention measures focused on MAs are warranted.

Relationship between early follow-up and readmission within 30 and 90 days after ischemic stroke.

OBJECTIVE: To examine whether early follow-up with primary care or neurology is associated with lower all-cause readmissions within 30 and 90 days after acute ischemic stroke admission. METHODS: We performed a retrospective cohort study of patients who were discharged home after acute ischemic stroke, identified by ICD-9 and ICD-10 codes, using PharMetrics, a nationally representative claims database of insured Americans from 2009 to 2015. The primary predictor was outpatient primary care or neurology follow-up within 30 and 90 days of discharge, and the primary outcome was all-cause 30- and 90-day readmissions. Multivariable Cox models were used with primary care and neurology visits specified as time-dependent covariates, with adjustment for patient demographics, comorbid conditions, and stroke severity measures. RESULTS: The cohort included 14,630 patients. Readmissions within 30 days occurred in 7.3% of patients, and readmissions within 90 days occurred in 13.7% of patients. By 30 days, 59.3% had a primary care visit, and 24.4% had a neurology visit. Primary care follow-up was associated with reduced 30-day readmissions (hazard ratio [HR] 0.84, 95% confidence interval [CI] 0.72-0.98). Primary care follow-up before 90 days did not reach significance (HR 0.92, 95% CI 0.83-1.03). Neurology follow-up was not associated with reduced readmissions within 30 or 90 days (HR 1.05, 95% CI; HR 1.00, 95% CI, respectively). CONCLUSION: Early outpatient follow-up with primary care is associated with a reduction in 30-day hospital readmissions. Early outpatient follow-up may represent an important opportunity for intervention after acute stroke admissions.

Ambulatory Clinician's Guide to Inpatient Service: An Innovative Rapid Onboarding Strategy for the COVID-19 Pandemic.

BACKGROUND AND SIGNIFICANCE: When hospitals are subject to prolonged surges in patients, such as during the coronavirus disease 2019 (COVID-19) pandemic, additional clinicians may be needed to care for the rapid increase of acutely ill patients. How might we quickly prepare a large number of ambulatory-based clinicians to care for hospitalized patients using the inpatient workflow of the electronic health record (EHR)? OBJECTIVES: The aim of the study is to create a successful training intervention which prepares ambulatory-based clinicians as they transition to inpatient services. METHODS: We created a training guide with embedded videos that describes the workflow of an inpatient clinician. We delivered this intervention via an e-mail hyperlink, a static hyperlink inside of the EHR, and an on-demand hyperlink within the EHR. RESULTS: In anticipation of the first peak of inpatients with COVID-19 in April 2020, the training manual was accessed 261 times by 167 unique users as clinicians anticipated being called into service. As our institution has not yet needed to deploy ambulatory-based clinicians for inpatient service, usage data of the training document is still pending. CONCLUSION: We intend that our novel implementation of a multimedia, highly accessible onboarding document with access from points inside and outside of the EHR will improve clinician performance and serve as a helpful example to other organizations during the COVID-19 pandemic and beyond.

Coding and billing issues in hospital neurology compensation.

BACKGROUND: Accurate coding and billing are critical for the financial health of hospitals. Neurologic inpatient services have specific, complex documentation requirements, which can result in inadequate billing. METHODS: We retrospectively compared coding practices from July 2013 to June 2014 (FY2014) using evaluation and management codes for initial inpatient encounters (CPT 99221-3) of a neurohospitalist group (NHG) to a hospital medicine group (HMG) and to national benchmarks. We further examined a sample of the lowest level encounters (CPT 99221) from the 4th quarter of FY2014 for specific deficiencies and compared these among groups. RESULTS: Low codes (CPT 99221) were more common in the NHG than the HMG and national benchmarks (54% vs 7% vs 4%, p < 0.01). Deficiencies in the examination were the most common reason for low coding in the NHG compared to the HMG (62% vs 5%, p < 0.001). Deficiencies in social history were more common in the NHG than the HMG (11% vs 0%, p < 0.003) but deficiencies in family history (34% vs 37%, p = 0.75) and review of systems (30% vs 30%, p = 1.0) were common in both groups. In the NHG group, documentation did not reflect the acuity of patients' medical conditions. CONCLUSIONS: Neurologists should pay close attention to documentation requirements-especially the neurologic examination-in order to allow for accurate coding and billing.

Inpatient Falls: Defining the Problem and Identifying Possible Solutions. Part II: Application of Quality Improvement Principles to Hospital Falls.

In this 2 part series, analysis of the risk stratification tools that are available and definition of the scope of the problem and potential solutions through a review of the literature is presented. A systematic review was used to identify articles for risk stratification and interventions. Three risk stratification systems are discussed, STRATIFY, Morse Fall Scale, and the Hendrich Fall Risk Model (HFRM). Of these scoring systems, the HFRM is the easiest to use and score. Predominantly, multifactorial interventions are used to prevent patient falls. Education and rehabilitation are common themes in studies with statistically significant results. The second article presents a guide to implementing a quality improvement project around hospital falls. A 10-step approach to Plan-Do-Study-Act (PDSA) cycles is described. Specific examples of problems and analysis are easily applicable to any institution. Furthermore, the sustainability of interventions and targeting new areas for improvement are discussed. Although specific to falls in the hospitalized patient, the goal is to present a stepwise approach that is broadly applicable to other areas requiring quality improvement.

Outpatient cardiac telemetry detects a high rate of atrial fibrillation in cryptogenic stroke.

BACKGROUND: The etiology of cerebral ischemia is undetermined in one-third of patients upon discharge. Occult paroxysmal atrial fibrillation (PAF) is considered a potential etiology. A high rate of PAF detection with 21-day mobile cardiac outpatient telemetry (MCOT) has been reported in two small studies. Optimal monitoring duration and factors predicting PAF have not been adequately defined. METHODS: We performed a retrospective analysis on patients evaluated by MCOT monitoring within 6 months of a cryptogenic stroke or TIA. Multivariate analysis with survival regression methods was performed using baseline characteristics to determine predictive risk factors for detection of PAF. Kaplan-Meier estimates were computed for 21-day PAF rates. RESULTS: We analyzed 156 records; PAF occurred in 27 of 156 (17.3%) patients during MCOT monitoring of up to 30 days. The rate of PAF detection significantly increased from 3.9% in the initial 48 h, to 9.2% at 7 days, 15.1% at 14 days, and 19.5% by 21 days (p<0.05). Female gender, premature atrial complex on ECG, increased left atrial diameter, reduced left ventricular ejection fraction and greater stroke severity were independent predictors of PAF detection on multivariate analysis with strongest correlation seen for premature atrial complex on ECG (HR 13.7, p=0.001). CONCLUSION: MCOT frequently detects PAF in patients with cryptogenic stroke and TIA. Length of monitoring is strongly associated with detection of PAF, with an optimal monitoring period of at least 21 days. Of the predictors of PAF detection, the presence of premature atrial complexes on ECG held the strongest correlation with PAF.

Safety of thrombolysis in acute ischemic stroke: a review of complications, risk factors, and newer technologies.

Intravenous recombinant tissue plasminogen activator (r-tPA) was approved for use in acute ischemic stroke in the United States in 1996. Approximately 2% to 5% of patients with acute ischemic stroke receive r-tPA. Complications related to intravenous r-tPA include symptomatic intracranial hemorrhage, major systemic hemorrhage, and angioedema in approximately 6%, 2%, and 5% of patients, respectively. Risk factors for symptomatic hemorrhage include age, male gender, obesity, increased stroke severity, diabetes, hyperglycemia, uncontrolled hypertension, combination antiplatelet use, large areas of early ischemic change, atrial fibrillation, congestive heart failure, and leukoariosis. A risk factor for angioedema is the use of angiotensin-converting enzyme inhibitor. Risk assessment scores, novel imaging strategies, and telemedicine may offer methods of optimizing the risk-benefit ratio.
