Neurologic Quality of Life Outcomes in Patients with Normal Pressure Hydrocephalus After Ventriculoperitoneal Shunt Placement: A Prospective Assessment of Cognition, Mobility, and Social Participation.

BACKGROUND: Idiopathic normal pressure hydrocephalus (iNPH) typically presents with gait disturbances, cognitive decline, and urinary incontinence. Symptomatic improvement generally occurs following shunt placement, but limited evidence exists on the quality of life (QOL) metrics in iNPH. Therefore, we conducted a prospective study of the effect of shunt placement on QOL in iNPH patients, using Quality of Life in Neurologic Disorders (Neuro-QOL) metrics. METHODS: Eligible patients underwent shunt placement after evidence of symptomatic improvement following temporary cerebrospinal fluid diversion via inpatient lumbar drain trial. Patients were administered short- and long-form Neuro-QOL assessments prior to shunt placement and at 6-month and 1-year postoperative timepoints to evaluate lower extremity mobility, cognitive function, and social roles and activities participation. Changes in QOL measures were analyzed using a repeated-measures linear mixed effects model. RESULTS: There were 48 patients with a mean age of 75.4 ± 6.3 years. Average short-form mobility scores improved by 3.9 points (14.6%) at 6-month follow-up and by 6.2 points (23.2%) at 1-year follow-up compared with preoperative baseline (P = 0.027 and P = 0.0002, respectively). Short-form cognition scores increased by 5.2 points (22.4%) at 6 months and 10.9 points (47.0%) at 1 year postoperatively (P = 0.007 and P < 0.0001, respectively). On long-form assessment, social roles and activity participation scores improved by 29.3 points (23.4%) at 6 months and 31.6 points (25.2%) at 1 year after surgery compared to baseline (P = 0.028 and P = 0.02, respectively). CONCLUSIONS: Our findings demonstrate that shunt placement leads to improved QOL in iNPH patients across multiple domains. Significant improvements in mobility, cognition, and social roles and activity participation are realized within the first 6 months and are sustained on 1-year follow-up.

Validation of a Novel Neurologic Assessment Test for Healthcare Staff.

ABSTRACT: BACKGROUND: To measure the effectiveness of an educational intervention, it is essential to develop high-quality, validated tools to assess a change in knowledge or skills after an intervention. An identified gap within the field of neurology is the lack of a universal test to examine knowledge of neurological assessment. METHODS: This instrument development study was designed to determine whether neuroscience knowledge as demonstrated in a Neurologic Assessment Test (NAT) was normally distributed across healthcare professionals who treat patients with neurologic illness. The variables of time, knowledge, accuracy, and confidence were individually explored and analyzed in SAS. RESULTS: The mean (standard deviation) time spent by 135 participants to complete the NAT was 12.9 (3.2) minutes. The mean knowledge score was 39.5 (18.2), mean accuracy was 46.0 (15.7), and mean confidence was 84.4 (24.4). Despite comparatively small standard deviations, Shapiro-Wilk scores indicate that the time spent, knowledge, accuracy, and confidence are nonnormally distributed ( P < .0001). The Cronbach α was 0.7816 considering all 3 measures (knowledge, accuracy, and confidence); this improved to an α of 0.8943 when only knowledge and accuracy were included in the model. The amount of time spent was positively associated with higher accuracy ( r2 = 0.04, P < .05), higher knowledge was positively associated with higher accuracy ( r2 = 0.6543, P < .0001), and higher knowledge was positively associated with higher confidence ( r2 = 0.4348, P < .0001). CONCLUSION: The scores for knowledge, confidence, and accuracy each had a slightly skewed distribution around a point estimate with a standard deviation smaller than the mean. This suggests initial content validity in the NAT. There is adequate initial construct validity to support using the NAT as an outcome measure for projects that measure change in knowledge. Although improvements can be made, the NAT does have adequate construct and content validity for initial use.

Automated Pupillometry as a Triage and Assessment Tool in Patients with Traumatic Brain Injury.

OBJECTIVE: Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in young adults. Automated infrared pupillometry (AIP) has shown promising results in predicting neural damage in aneurysmal subarachnoid hemorrhage and ischemic stroke. We aimed to explore potential uses of AIP in triaging patients with TBI. We hypothesized that a brain injury severe enough to require an intervention would show Neurologic Pupil Index (NPI) changes. METHODS: We conducted a prospective pilot study at a level-1 trauma center between November 2019 and February 2020. AIP readings of consecutive patients seen in the emergency department with blunt TBI and abnormal imaging findings on computed tomography were recorded by the assessing neurosurgery resident. The relationship between NPI and surgical intervention was studied. RESULTS: Thirty-six patients were enrolled, 9 of whom received an intervention. NPI was dichotomized into normal (≥3) versus abnormal (<3) and was predictive of intervention (Fisher exact test; P < 0.0001). Six of the 9 patients had a Glasgow Coma Scale (GCS) score ≤8 and imaging signs of increased intracranial pressure (ICP) and underwent craniectomy (n = 4) or ICP monitor placement (n = 2) and had an abnormal NPI. Three patients underwent ICP monitor placement for GCS score ≤8 in accordance with TBI guidelines despite minimal imaging findings and had a normal NPI. The GCS score of these patients improved within 24 hours, requiring ICP monitor removal. NPI was normal in all patients who did not require intervention. CONCLUSIONS: AIP could be useful in triaging comatose patients after blunt TBI. An NPI ≥3 may be reassuring in patients with no signs of mass effect or increased ICP.

Objective Pupillometry as an Adjunct to Prediction and Assessment for Oculomotor Nerve Injury and Recovery: Potential for Practical Applications.

BACKGROUND: Pupillary light reflex examinations are intrinsic to any good neurological examination. Consistent evidence has shown that automated pupillometry assessments provide superior accuracy and interrater correlation compared with bedside eye examinations. Pupillary indexes such as the neurological pupil index (NPI) can also provide several hours of warning before the advent of herniation syndromes or third nerve palsy. METHODS: We determined the unique temporal relationship between NPI changes and third nerve palsy occurrence and recovery in an initially neurologically intact hospitalized patient. A 53-year-old woman presented with aneurysmal subarachnoid hemorrhage and headaches. Her aneurysm was treated surgically without complications. After lumbar drainage for hydrocephalus, she developed isolated left third nerve palsy that slowly recovered over the following weeks. Pupilometer data were obtained throughout her hospital stay. RESULTS: A total of 121 pupillary measurement sets were obtained. The NPI had decreased to an abnormal level (<3) 12 hours before she became symptomatic. The NPI also started improving 24 hours before improvement in her clinical examination. The patient did not display signs of neurological dysfunction related to vasospasm during her stay. CONCLUSION: The NPI seems to reliably correlate with third nerve function and appears to possess predictive temporal properties that could allow practitioners to anticipate neurological injury and recovery. These findings could affect the fields of neurosciences, trauma, military medicine, critical care, and ophthalmology.

The impact of motivational interviewing on self-perceived burden in patients receiving therapeutic plasma exchange.

BACKGROUND: Autoimmune disorders and neurodegenerative disorders take a physical and emotional toll on patients that undergo therapeutic plasma exchange (TPE) treatments. Previous literature has shown that these patients may feel a greater sense of self-burden. Motivational Interviewing (MI) is a technique used in various settings that has the potential to decrease feelings of self-burden. MI for patients who receive TPE has not been tested. The purpose of this study was to examine the impact of MI in patients with a neurodegenerative diagnosis (eg, transverse myelitis, myasthenia gravis, multiple sclerosis, and chronic inflammatory demyelinating polyneuropathy) that are undergoing TPE treatments. METHODS: This was a prospective, non-randomized, longitudinal study of the impact of MI with patients at high risk of sense of self-burden who underwent apheresis treatments. Consented patients underwent three to six MI sessions with a trained clinician. Patients completed a self-report baseline and post-test of self-perceived burden. RESULTS: Thirty participants consented to the study; 27 were included in the analysis. The Self-Perceived Burden Scale scores were significantly higher at baseline (m = 26.2) when compared to scores post MI sessions (m = 21.48, P < .05). The number of MI sessions (3, 4, 5, 6 sessions) did not significantly impact the outcome score (r2 = 0.001; P = .901). CONCLUSION: MI is a straightforward technique that is feasible and shown to be effective to be used by bedside clinicians while working with patients who receive TPE to decrease levels of self-perceived burden.

Formatting an experiential learning education module to encourage dysphagia assessment in apheresis patients.

BACKGROUND: Dysphagia screening is oftentimes a focus of hospitalized patients, but dysphagia can also occur in outpatient settings. Dysphagia can be overlooked by nurses and clinicians, and it is therefore important to educate nurses on the importance of dysphagia screenings. METHODS: This was a randomized prospective pilot study to compare the effect of experiential learning versus traditional PowerPoint learning regarding nurses' attitudes towards performing dysphagia screening in an outpatient setting. Twelve pre and post-test surveys were collected from nurses working in outpatient apheresis about their attitudes towards dysphagia screening. Additionally, 128 electronic medical records (EMR) were reviewed to determine if education increased the occurrence of dysphagia screening. RESULTS: There was a statistically significant difference in the pre vs. post-test group scores (P < .001), but due to small sample size, there was insufficient evidence to reject the null hypothesis that nurses had changed their attitudes towards dysphagia screening. Comparing documentation of dysphagia assessment in the EMR, there was not a significant difference in practice before or after the educational intervention (P = 0.18). CONCLUSIONS: The study results showed that the both types of teaching strategies are possible with nurses and they were receptive to both. Although the results of this study did not show a significant difference in practice, more research is needed to determine how to raise awareness and put this into practice.

Nurses Perceptions of a Novel Protocol Addressing Uniform Periods of Minimum Assessment Times.

AIMS AND OBJECTIVES: This quality improvement project aimed to understand the impact of a quiet time protocol on nurses and patients in the neurocritical care unit (NCCU) by comparing pretest and posttest outcomes, taking decibel readings, and abstracting chart information. BACKGROUND: Sleep is essential for maintaining a healthy life. Patients in the NCCU often do not get adequate amounts of sleep. Quiet time studies have focused on implementing periods of reduced noise levels to improve patient sleep. However, the perceptions of the caregivers about the protocols have not been taken into consideration, leading to difficulty in implementing these protocols if it impedes with the routine work of the caregivers. METHODS: This was a prospective quality improvement project, with a quiet time protocol in the novel setting of the NCCU with caregiver feedback on the protocol. The quiet protocol involved decreasing light, noise, and patient interactions between 11:30 PM and 2:30 AM. There were 16 nurses who consented to the study and provided feedback via self-report questionnaires. RESULTS: Implementation of this protocol did not suggest a decrease in nurse enjoyment with their job (P = .51). There were significant improvements in patient sleep quality and quantity (P < .0001). In addition, there was some evidence of decrease in the noise level and number of patient disruptions. CONCLUSIONS: The results of this single-site project suggest that, by implementing a quiet time protocol in the NCCU, patients obtained higher levels of sleep quality and quantity. The implementation of this protocol did not impact nurses' job satisfaction, suggesting that the quiet time protocol is possible, improves patients care, and does not hinder nurses' job satisfaction.

Establishing Normative Data for Pupillometer Assessment in Neuroscience Intensive Care: The "END-PANIC" Registry.

BACKGROUND: Trained medical practitioners have been assessing the pupillary light reflex for more than 2 millennia. However, the interrater reliability of the pupillary light reflex remains low. To overcome the drawbacks of a subjective interpretation of pupillary size and reactivity, automated pupillometers are becoming increasingly commonplace, but practitioners do not have adequate data from which to judge whether the numerical values provided by the pupillometer are "within reference limits." METHODS: This article details the methods used to create an extensive database of automated pupillometer readings and associated patient data (eg, intracranial pressure). DISCUSSION/CONCLUSIONS: The "Establishing Normative Data for Pupillometer Assessments in Neuroscience Intensive Care" Registry will provide a large data set of pupillary size, reactivity, and speed of contraction in a cohort of patients admitted to a neuroscience intensive care unit with a variety of conditions. Analysis of this data set will help establish normative data for pupillometer readings for neurologically impaired patients. Exploratory analysis of this data set may also provide preliminary hypothesis generating data for future prospective studies on pupillary findings and trends in acute neurological conditions.

Toward Solving the Sedation-Assessment Conundrum: Neurofunction Monitoring.

The sedation-assessment conundrum is the struggle to balance the need for sedation against the need to awaken the patient and perform a neurologic examination. This article discusses the nuances of the sedation-assessment conundrum as well as approaches to resolve this and reduce the negative impact of abruptly stopping sedative infusions. Both oversedation and undersedation affect critically ill patients. This article discusses methods of assessing sedation and interpreting individualized patient responses to sedation. The use of neurofunction monitors and periods of sedation interruption are discussed within the context of addressing the sedation-assessment conundrum.

Association of Get With The Guidelines-Stroke Program Participation and Clinical Outcomes for Medicare Beneficiaries With Ischemic Stroke.

BACKGROUND AND PURPOSE: Get With The Guidelines (GWTG)-Stroke is a national, hospital-based quality improvement program developed by the American Heart Association. Although studies have suggested improved processes of care in GWTG-Stroke-participating hospitals, it is not known whether this improved care translates into improved clinical outcomes compared with nonparticipating hospitals. METHODS: From all acute care US hospitals caring for Medicare beneficiaries with acute stroke between April 2003 and December 2008, we matched hospitals that joined the GWTG-Stroke program with similar hospitals that did not. Using a difference-in-differences design, we analyzed whether hospital participation in GWTG-Stroke was associated with a greater improvement in clinical outcomes compared with the underlying secular change. RESULTS: The matching algorithm identified 366 GWTG-Stroke-adopting hospitals that cared for 88 584 acute ischemic stroke admissions and 366 non-GWTG-Stroke hospitals that cared for 85 401 acute ischemic stroke admissions. Compared with the Pre period (18-6 months before program implementation), in the Early period (0-6 months after program implementation), GWTG-Stroke hospitals had accelerated increases in discharge to home and reduced mortality at 30 days and 1 year. In the Sustained period (6-18 months after program implementation), the accelerated reduction in mortality at 1 year was sustained, with a trend toward sustained accelerated increase in discharge home. CONCLUSIONS: Hospital adoption of the GWTG-Stroke program was associated with improved functional outcomes at discharge and reduced postdischarge mortality.

Clinical Effectiveness of Statin Therapy After Ischemic Stroke: Primary Results From the Statin Therapeutic Area of the Patient-Centered Research Into Outcomes Stroke Patients Prefer and Effectiveness Research (PROSPER) Study.

BACKGROUND: In patients with ischemic stroke, data on the real-world effectiveness of statin therapy for clinical and patient-centered outcomes are needed to better inform shared decision making. METHODS AND RESULTS: Patient-Centered Research Into Outcomes Stroke Patients Prefer and Effectiveness Research (PROSPER) is a Patient-Centered Outcomes Research Institute-funded research program designed with stroke survivors to evaluate the effectiveness of poststroke therapies. We linked data on patients ≥65 years of age enrolled in the Get With The Guidelines-Stroke Registry to Medicare claims. Two-year to postdischarge outcomes of those discharged on a statin versus not on a statin were adjusted through inverse probability weighting. Our coprimary outcomes were major adverse cardiovascular events and home time (days alive and out of a hospital or skilled nursing facility). Secondary outcomes included all-cause mortality, all-cause readmission, cardiovascular readmission, and hemorrhagic stroke. From 2007 to 2011, 77 468 patients who were not taking statins at the time of admission were hospitalized with ischemic stroke; of these, 71% were discharged on statin therapy. After adjustment, statin therapy at discharge was associated with a lower hazard of major adverse cardiovascular events (hazard ratio, 0.91; 95% confidence interval, 0.87-0.94), 28 more home-time days after discharge (P<0.001), and lower all-cause mortality and readmission. Statin therapy at discharge was not associated with increased risk of hemorrhagic stroke (hazard ratio, 0.94; 95% confidence interval, 0.72-1.23). Among statin-treated patients, 31% received a high-intensity dose; after risk adjustment, these patients had outcomes similar to those of recipients of moderate-intensity statin. CONCLUSION: In older ischemic stroke patients who were not taking statins at the time of admission, discharge statin therapy was associated with lower risk of major adverse cardiovascular events and nearly 1 month more home time during the 2-year period after hospitalization.

Perception Versus Actual Performance in Timely Tissue Plasminogen Activation Administration in the Management of Acute Ischemic Stroke.

BACKGROUND: Timely thrombolytic therapy can improve stroke outcomes. Nevertheless, the ability of US hospitals to meet guidelines for intravenous tissue plasminogen activator (tPA) remains suboptimal. What is unclear is whether hospitals accurately perceive their rate of tPA "door-to-needle" (DTN) time within 60 minutes and how DTN rates compare across different hospitals. METHODS AND RESULTS: DTN performance was defined by the percentage of treated patients who received tPA within 60 minutes of arrival. Telephone surveys were obtained from staff at 141 Get With The Guidelines hospitals, representing top, middle, and low DTN performance. Less than one-third (29.1%) of staff accurately identified their DTN performance. Among middle- and low-performing hospitals (n=92), 56 sites (60.9%) overestimated their performance; 42% of middle performers and 85% of low performers overestimated their performance. Sites that overestimated tended to have lower annual volumes of tPA administration (median 8.4 patients [25th to 75th percentile 5.9 to 11.8] versus 10.2 patients [25th to 75th percentile 8.2 to 17.3], P=0.047), smaller percentages of eligible patients receiving tPA (84.7% versus 89.8%, P=0.008), and smaller percentages of DTN ≤60 minutes among treated patients (10.6% versus 16.6%, P=0.002). CONCLUSIONS: Hospitals often overestimate their ability to deliver timely tPA to treated patients. Our findings indicate the need to routinely provide comparative provider performance rates as a key step to improving the quality of acute stroke care.

The Adam Williams initiative: collaborating with community resources to improve care for traumatic brain injury.

BACKGROUND: The Brain Trauma Foundation has developed treatment guidelines for the care of patients with acute traumatic brain injury. However, a method to provide broad acceptance and application of these guidelines has not been published. OBJECTIVE: To describe methods for the development, funding, and continued educational efforts of the Adam Williams Initiative; the experiences from the first 10 years may serve as a template for hospitals and nurses that seek to engage in long-term quality improvement collaborations with foundations and/or industry. METHODS: In 2004, the nonprofit Adam Williams Initiative was established with the goal of providing education and resources that would encourage hospitals across the United States to incorporate the Brain Trauma Foundation's guidelines into practice. RESULTS: Between 2004 and 2014, 37 hospitals have been funded by the Adam Williams Initiative and have had staff members participate in an immersion experience at Mission Hospital (Mission Viejo, California) during which team members received both didactic and hands-on education in the care of traumatic brain injury. CONCLUSIONS: Carefully cultivated relationships and relentless teamwork have contributed to successful implementation of the Brain Trauma Foundation's guidelines in US hospitals.

Insurance status and outcome after intracerebral hemorrhage: findings from Get With The Guidelines-stroke.

BACKGROUND: [corrected] Few studies have examined associations among insurance status, treatment, and outcomes in patients hospitalized for intracerebral hemorrhage (ICH). METHODS: Through retrospective analyses of the Get With The Guidelines (GWTG)-Stroke database, a national prospective stroke registry, from April 2003 to April 2011, we identified 95,986 nontransferred subjects hospitalized with ICH. Insurance status was categorized as Private/Other, Medicaid, Medicare, or None/Not Documented (ND). Associations between insurance status and in-hospital outcomes and quality of care measures were analyzed using patient- and hospital-specific variables as covariates. RESULTS: There were significant differences in age and frequency of comorbid conditions by insurance group. Compliance with evidence-based quality of care indicators varied across all insurance status groups (P < .0001) but was generally high. In adjusted analysis with the Private insurance group as reference, the None/ND group most consistently demonstrated higher odds ratios (ORs) for quality of care measures (Dysphagia Screen: OR 1.10, 95% confidence interval [CI] 1.02-1.17, P = .0096; Stroke Education: OR 1.16, 95% CI 1.05-1.29, P = .0042; and Rehabilitation: OR 1.25, 95% CI 1.08-1.44, P = .0027). In-hospital mortality rates were higher for None/ND, Medicaid, and Medicare patients; after risk adjustment, the None/ND group had the highest mortality risk (OR 1.29, 95% CI 1.21-1.38, P < .0001). Medicare and Medicaid patients had lower adjusted odds for both independent ambulation at discharge and discharge to home when compared with the Private/Other group. CONCLUSIONS: GWTG-Stroke ICH patients demonstrated differences in mortality, functional status, discharge destination, and quality of care measures associated with insurance status.

Exploring the impact of augmenting sedation assessment with physiologic monitors.

BACKGROUND: Pharmacological sedation is a necessary tool in the management of critically ill, mechanically ventilated patients. The intensive care unit (ICU) sedation strategy is to use the least amount of medication to meet safety and comfort goals. Titration of pharmacological agents is currently guided by clinical assessment tools. The purpose of this study was to determine whether the addition of a neurophysiological monitor, bispectral index (BIS), aided the ICU nurse in reducing the amount of drug used, compared to a clinical tool alone, in a general critical care population. METHODS: In this prospective clinical trial, mechanically ventilated adults (N=300) were randomised to sedation assessment using only the observational assessment tool (RASS) or a combination of observational and physiologic measures (RASS+BIS). Subjects were enrolled from a medical ICU (N=154), a trauma ICU (N=72) and a general mixed-use ICU (N=74). RESULTS: BIS-augmented sedation was only associated with the reduction of drug use when patients were sedated with propofol or narcotic agents (propofol [1.61 mg/kg/h vs. 1.77 mg/kg/h; p<0.0001], fentanyl [54.73 mcg/h vs. 66.81 mcg/h; p<0.0001], and hydromorphone [0.97 mg/h vs. 4.00 mg/h: p<0.0001] compared to RASS alone. In contrast, patients sedated with dexmedetomidine or benzodiazepines were given higher doses under the BIS-augmented dexmedetomidine [0.46 mcg/kg/h vs. 0.33 mcg/kg/h; p<0.0001], lorazepam [4.13 mg/h vs. 3.29 mg/h p<0.0001], and midazolam [3.73 mg/h vs 2.86 mg/h; p<0.0001]) protocol compared to clinical assessment alone. CONCLUSION: The clinical evaluation of depth of sedation remains the most reliable method for the titration of pharmacological sedation in the critical care unit. However, BIS-augmented assessment is helpful in reducing the amount of propofol and narcotic medication used and may be considered an adjunct when these agents are utilised.

Interrater reliability of the bedside shivering assessment scale.

BACKGROUND: Since its early development, the Bedside Shivering Assessment Scale (BSAS) has had only initial psychometric testing. Before this instrument is incorporated into routine practice, its interrater reliability should be explored in a diverse group of practitioners. METHODS: This prospective nonrandomized study used a panel of 5 observers who completed 100 paired assessments. Observers independently scored patients for shivering by using the BSAS. Kappa statistics were determined by using SAS version 9.4 with BSAS scores treated as ordinal data. RESULTS: A weighted kappa value of 0.48 from 100 paired observations of 22 patients indicates moderate agreement of the BSAS scores. Most of the BSAS scores were 0 or 1; dichotomizing shivering as little or no shivering versus significant shivering resulted in a kappa of 0.66 (substantial agreement). No relationship was found between timing of assessment or the role of the practitioner and the likelihood of both observers assigning the same BSAS score. CONCLUSION: The BSAS has adequate interrater reliability to be considered for use among a diverse group of practitioners.

Comparison of 30-day mortality models for profiling hospital performance in acute ischemic stroke with vs without adjustment for stroke severity.

CONTEXT: There is increasing interest in reporting risk-standardized outcomes for Medicare beneficiaries hospitalized with acute ischemic stroke, but whether it is necessary to include adjustment for initial stroke severity has not been well studied. OBJECTIVE: To evaluate the degree to which hospital outcome ratings and potential eligibility for financial incentives are altered after including initial stroke severity in a claims-based risk model for hospital 30-day mortality for acute ischemic stroke. DESIGN, SETTING, AND PATIENTS: Data were analyzed from 782 Get With The Guidelines-Stroke participating hospitals on 127,950 fee-for-service Medicare beneficiaries with ischemic stroke who had a score documented for the National Institutes of Health Stroke Scale (NIHSS, a 15-item neurological examination scale with scores from 0 to 42, with higher scores indicating more severe stroke) between April 2003 and December 2009. Performance of claims-based hospital mortality risk models with and without inclusion of NIHSS scores for 30-day mortality was evaluated and hospital rankings from both models were compared. MAIN OUTCOMES MEASURES: Model discrimination, hospital 30-day mortality outcome rankings, and value-based purchasing financial incentive categories. RESULTS: Across the study population, the mean (SD) NIHSS score was 8.23 (8.11) (median, 5; interquartile range, 2-12). There were 18,186 deaths (14.5%) within the first 30 days, including 7430 deaths (5.8%) during the index hospitalization. The hospital mortality model with NIHSS scores had significantly better discrimination than the model without (C statistic, 0.864; 95% CI, 0.861-0.867, vs 0.772; 95% CI, 0.769-0.776; P < .001). Among hospitals ranked in the top 20% or bottom 20% of performers by the claims model without NIHSS scores, 26.3% were ranked differently by the model with NIHSS scores. Of hospitals initially classified as having "worse than expected" mortality, 57.7% were reclassified to "as expected" by the model with NIHSS scores. The net reclassification improvement (93.1%; 95% CI, 91.6%-94.6%; P < .001) and integrated discrimination improvement (15.0%; 95% CI, 14.6%-15.3%; P < .001) indexes both demonstrated significant enhancement of model performance after the addition of NIHSS. Explained variance and model calibration was also improved with the addition of NIHSS scores. CONCLUSION: Adding stroke severity as measured by the NIHSS to a hospital 30-day risk model based on claims data for Medicare beneficiaries with acute ischemic stroke was associated with considerably improved model discrimination and change in mortality performance rankings for a substantial portion of hospitals.

A qualitative assessment of practices associated with shorter door-to-needle time for thrombolytic therapy in acute ischemic stroke.

Early treatment with intravenous (IV) recombinant tissue plasminogen activator/alteplase (tPA) is associated with improved outcomes for patients with an acute ischemic stroke. Thus, rapid triage and treatment of stroke patients are essential, with a goal of door-to-needle time of no more than 60 minutes. We sought to identify best practices associated with faster treatment among hospitals participating in Get With the Guidelines--Stroke. Qualitative telephone interviews were conducted to elicit strategies being used by these centers to assess, treat, and monitor stroke patients treated with IV tPA. We sequentially carried out these interviews until we no longer identified novel factors. Interviews were conducted with 13 personnel at 7 top-performing U.S. hospitals. With the use of a hermeneutic-phenomenological framework, 5 distinct domains associated with rapid IV tPA delivery were identified. These included (a) communication and teamwork, (b) process, (c) organizational culture, (d) performance monitoring and feedback, and (e) overcoming barriers.

Are quality improvements in the get with the guidelines: stroke program related to better care or better data documentation?

BACKGROUND- Increased compliance with performance measures could reflect better care or better data documentation. We examined trends in the documentation of eligibility criteria, treatment contraindications, and missing data in the Get With The Guidelines-Stroke program to quantify their contribution to increased performance measure compliance. METHODS AND RESULTS- Data on 569 883 ischemic stroke admissions to 1028 GWTG-Stroke hospitals between April 2003 and September 2009 were obtained. Seven measures were examined: intravenous recombinant tissue plasminogen activator therapy, early antithrombotics, deep vein thrombosis prophylaxis, anticoagulants for atrial fibrillation/flutter, discharge antithrombotics, lipid therapy, and smoking cessation. Within each target population, the proportion of subjects treated, not treated, not treated because of contraindications, or with missing data were generated by calendar year. There were minimal changes in the size of the target populations for 6 of the measures; however, the size of the deep vein thrombosis prophylaxis population was reduced ≈5% in 2008 because of a format change to the data collection form. All measures showed significant increases in the proportion of eligible subjects treated across the study period. These increases occurred without major shifts in contraindications or missing data, with the exception of anticoagulation for atrial fibrillation/flutter where the increase occurred in conjunction with a decline in contraindications. Similar findings were seen when the data were examined by the duration of hospital participation in the program. CONCLUSIONS- These findings suggest that the majority of performance improvement in the Get With The Guidelines-Stroke program represent an increase in the number of patients with stroke treated and not changes to the underlying target populations or documentation of contraindications or missing data.
