Door to needle time trends after transition to tenecteplase: A Multicenter Texas stroke registry.

BACKGROUND: Tenecteplase (TNK) is considered a promising option for the treatment of acute ischemic stroke (AIS) with the potential to decrease door-to-needle times (DTN). This study investigates DTN metrics and trends after transition to tenecteplase. METHODS: The Lone Star Stroke (LSS) Research Consortium TNK registry incorporated data from three Texas hospitals that transitioned to TNK. Subject data mapped to Get-With-the-Guidelines stroke variables from October 1, 2019 to March 31, 2023 were limited to patients who received either alteplase (ALT) or TNK within the 90 min DTN times. The dataset was stratified into ALT and TNK cohorts with univariate tables for each measured variable and further analyzed using descriptive statistics. Logistic regression models were constructed for both ALT and TNK to investigate trends in DTN times. RESULTS: In the overall cohort, the TNK cohort (n = 151) and ALT cohort (n = 161) exhibited comparable population demographics, differing only in a higher prevalence of White individuals in the TNK cohort. Both cohorts demonstrated similar clinical parameters, including mean NIHSS, blood glucose levels, and systolic blood pressure at admission. In the univariate analysis, no difference was observed in median DTN time within the 90 min time window compared to the ALT cohort [40 min (30-53) vs 45 min (35-55); P = .057]. In multivariable models, DTN times by thrombolytic did not significantly differ when adjusting for NIHSS, age (P = .133), or race and ethnicity (P = .092). Regression models for the overall cohort indicate no significant DTN temporal trends for TNK (P = .84) after transition; nonetheless, when stratified by hospital, a single subgroup demonstrated a significant DTN upward trend (P = 0.002). CONCLUSION: In the overall cohort, TNK and ALT exhibited comparable temporal trends and at least stable DTN times. This indicates that the shift to TNK did not have an adverse impact on the DTN stroke metrics. This seamless transition is likely attributed to the similarity of inclusion and exclusion criteria, as well as the administration processes for both medications. When stratified by hospital, the three subgroups demonstrated variable DTN time trends which highlight the potential for either fatigue or unpreparedness when switching to TNK. Because our study included a multi-ethnic cohort from multiple large Texas cities, the stable DTN times after transition to TNK is likely applicable to other healthcare systems.

Multicenter exploration of tenecteplase transition factors: A quantitative analysis.

BACKGROUND: Tenecteplase (TNK) is gaining recognition as a novel therapy for acute ischemic stroke (AIS). Despite TNK offering a longer half-life, time and cost saving benefits and comparable treatment and safety profiles to Alteplase (ALT), the adoption of TNK as a treatment for AIS presents challenges for hospital systems. OBJECTIVE: Identify barriers and facilitators of TNK implementation at acute care hospitals in Texas. METHODS: This prospective survey used open-ended questions and Likert statements generated from content experts and informed by qualitative research. Stroke clinicians and nurses working at 40 different hospitals in Texas were surveyed using a virtual platform. RESULTS: The 40 hospitals had a median of 34 (IQR 24.5-49) emergency department beds and 42.5 (IQR 23.5-64.5) inpatient stroke beds with 506.5 (IQR 350-797.5) annual stroke admissions. Fifty percent of the hospitals were Comprehensive Stroke Centers, and 18 (45 %) were solely using ALT for treatment of eligible AIS patients. Primary facilitators to TNK transition were team buy-in and a willingness of stroke physicians, nurses, and pharmacists to adopt TNK. Leading barriers were lack of clinical evidence supporting TNK safety profile inadequate evidence supporting TNK use and a lack of American Heart Association guidelines support for TNK administration in all AIS cases. CONCLUSION: Understanding common barriers and facilitators to TNK adoption can assist acute care hospitals deciding to implement TNK as a treatment for AIS. These findings will be used to design a TNK adoption Toolkit, utilizing implementation science techniques, to address identified obstacles and to leverage facilitators.

A qualitative study of barriers and facilitators to using tenecteplase to treat acute ischemic stroke.

BACKGROUND: Tenecteplase (TNK) is emerging as an alternative to alteplase (ALT) for thrombolytic treatment of acute ischemic stroke (AIS). Compared to ALT, TNK has a longer half-life, shorter administration time, lower cost, and similarly high efficacy in treating large vessel occlusion. Nevertheless, there are barriers to adopting TNK as a treatment for AIS. This study aimed to identify thematic barriers and facilitators to adopting TNK as an alternative to ALT as a thrombolytic for eligible AIS patients. METHODS: Qualitative research methodology using hermeneutic cycling and purposive sampling was used to interview four stroke clinicians in Texas. Interviews were recorded and transcribed verbatim. Enrollment was complete when saturation was reached. All members of the research team participated in content analysis during each cycle and in thematic analysis after saturation. RESULTS: Interviews were conducted between November 2022 and February 2023 with stroke center representatives from centers that either had successfully adopted TNK, or had not yet adopted TNK. Three themes and eight sub-themes were identified. The theme "Evidence" had three sub-themes: Pro-Con Balance, Fundamental Knowledge, and Pharmacotherapeutics. The theme "Process Flow" had four subthemes: Proactive, Reflective self-doubt, Change Process Barriers, and Parameter Barriers. The theme "Consensus" had one sub-theme: Getting Buy-In. CONCLUSION: Clinicians experience remarkably similar barriers and facilitators to adopting TNK. The results lead to a hypothesis that providing evidence to support a practice change, and identifying key change processes, will help clinicians achieve consensus across teams that need to 'buy in' to adopting TNK for AIS treatment.

Using Mobile Video-Teleconferencing to Deliver Secondary Stroke Prevention Interventions: A Pilot Study.

Objectives: Patient self-management support (SMS) interventions help stroke survivors control stroke risk factors and assist with secondary prevention. We examined utility and preliminary effectiveness of mobile video-teleconferencing (VT) to deliver SMS to stroke survivors in rural and low-income urban Texas communities. Methods: We applied a within-subjects design to assess improvement in self-management behaviors and stroke risk factors among stroke survivors receiving SMS intervention through mobile VT. Adults with stroke and two or more uncontrolled stroke risk factors were eligible. The SMS program, Video-teleconference-Self-management TO Prevent stroke (V-STOP) was delivered over 6 weeks by trained health coaches through VT. We applied Generalized Estimating Equations with site and time in intervention as covariates to evaluate psychological, social, physiological outcomes, self-management behaviors, and quality of life. Results: Mean age of 106 participants was 59.3 (±10.9); most were White, Hispanic men, living with someone, with low income. Approximately 69% completed all measures at 6 weeks. Median number of sessions attended was 5 (interquartile range 3) potentially avoiding 210 km of travel per person. Satisfaction with V-STOP and VT delivery was high, at (4.8 [±0.5]) and (4.7 [±0.5]), respectively. Stroke knowledge was improved from 8.8 (±1.0) at baseline to 9.6 (±0.7) at 12 weeks, (p < 0.0001). Improvements were observed in self-efficacy, exercise behaviors, depression and anxiety, disability, and quality of life. Conclusion: Implementation of SMS is feasible and shows good utility and preliminary effectiveness of using mobile VT to provide stroke follow-up care to stroke survivors. Participants improved self-management behaviors and stroke risk factors.

Veteran stroke survivors' lived experiences after being discharged home: a phenomenological study.

BACKGROUND: Stroke is a leading cause of disability in adults and third cause of death in the United States. Survivors face challenges postdischarge, including risks in self-management (SM) following prescribed regimens. Although SM education can help develop skills to control risk factors for stroke recurrence, little is known about lived experiences of patients adopting SM. AIMS: To examine Veterans' lived poststroke experiences after discharge and their experiences in SM goal setting/attainment. METHODS: Patients within one year of discharge from a Veterans Administration Medical Center in the United States with two risk factors for stroke recurrence were enrolled and received an SM workbook. Eight patients were interviewed (six males, two females; mean age 62: range 45-80). Part I concerned lived experience. Part II described experiences with goal setting and attainment. Data were analyzed inductively, identifying common experiences. Deductive analysis described goal setting and attainment. Transcript reviews identified SM themes and strategies. RESULTS: Lived experiences included 1) uncertainty about life, 2) anger and frustration, and 3) healthcare system challenges. Coping skills and setting goals to manage risks were critical for physical and emotional functioning. CONCLUSIONS: SM coping and goal setting aided recovery and improved life quality among Veterans after stroke. SM interventions assisted in regaining physical and emotional function. Findings may help in design of interventions for survivors, using SM and goal setting and attainment.IMPLICATIONS FOR REHABILITATIONSeveral implications for clinical practice were identified:Providers should acknowledge Veterans' challenges and struggles after their stroke and help Veterans to re-establish social identity, enhance self-esteem and improve mood.More emphasis should be given to the Veterans' caregivers' availability and willingness to help with their loved one's recovery, work reinstatement status and financial struggles.Recognition of the importance of the social context of recovery after a stroke is important, as nonmedical social interaction is often overlooked.Improvements are needed in the area of providers working with social workers and physical, occupational and mental health therapists to arrange more inpatient and outpatient treatments, including more frequent home visits.Veterans should be strongly encouraged to attend self-management diabetes education classes and smoking cessation and weight-loss programs offered for free within the Veterans Health Administration system.Self-management strategies using goal-setting and attainment concepts may assist individuals with stroke to regain physical and emotional functions, subsequently preventing another stroke.

Management of Lipids in Patients with Diabetes.

Abnormal lipids, sometimes referred to as diabetes dyslipidemia, is a common condition in patients with diabetes. With the increasing number of patients with abnormal lipids, especially those with type 2 diabetes, health care practitioners, including nurses, have to properly manage patients with diabetes as well as abnormal lipids. This article examines the pathophysiology of abnormal lipids, the management of abnormal lipids, and the lipid goals for patients with diabetes. Lastly, this article discusses pharmacologic and nonpharmacologic therapies and the role of primary care providers and nurses in the management of abnormal lipids.

The Relationship Between Lesion Localization and Dysphagia in Acute Stroke.

Factors that can facilitate early identification of individuals at risk of dysphagia such as stroke location are potentially of great benefit. The aim of this study was to examine the role of hemisphere and lesion location in assessing dysphagia pattern and airway invasion as identified through the use of validated, standardized interpretation measures for the videofluoroscopic swallowing study. Consecutive patients (N = 80) presenting with stroke symptoms who had a first-time acute ischemic stroke confirmed on diffusion-weighted magnetic resonance imaging (DW-MRI) scan participated. Three swallowing outcome variables were assessed using regression models: modified barium swallow impairment profile (MBSImP) oral impairment (OI) and pharyngeal impairment (PI) scores and penetration aspiration scale (PAS) score. Subjects were primarily male and demonstrated mild stroke and mild to moderate dysphagia. There was a significantly higher likelihood of abnormal PAS scores for infratentorial lesions compared to right hemisphere location (Odds ratio: 3.1, SE: 1.8, p = 0.046) and for Whites compared to African Americans (Odds ratio: 5.5, SE: 2.6, p = <0.001). However, OI scores were higher (worse) in African Americans compared to Whites (Beta = -1.2; SE: 0.56; p = 0.037). PI scores had no significant association with race or lesion location. Using DW-MRI to identify infratentorial stroke can help identify individuals at risk of airway invasion; however, imaging information concerning supratentorial infarct hemisphere and location may not be useful to predict which individuals with mild stroke are at risk for dysphagia and aspiration when admitted with acute stroke symptoms. Future studies should explore the role of race in the development of stroke-related dysphagia.

A Multiple Behavior Self-Monitoring Intervention for African- American Veterans with Type 2 Diabetes: A Feasibility Implementation Study.

The purpose of this study was to determine the feasibility of implementing a multiple-behavior self-monitoring intervention within a diabetes education program. This study was a 3-month pre- post-design, conducted with African-Americans (N = 20), who attended diabetes education classes at a large Veteran's Affairs (VA) hospital in Southwest Texas. Participants selfmonitored their blood glucose, diet, exercise, and weight on either a smart phone application or paper diaries. Paired t tests showed strong evidence that patient self-monitoring of healthy lifestyle behaviors improved blood glucose (t = -3.858, p = .001) and HbAlc (t = -4.428, p <.001), respectively. Moreover Spearman's correlation coefficient showed significant correlations between blood glucose and exercise (rs = -.68, p = .008) and HbAlc and exercise (rs = -.56, p = .036). This feasibility study showed that multiple-behavior self-monitoring was effective in lowering blood glucose and HbA1c levels among African-American Veterans; however, a randomized controlled trial with a larger sample is needed to validate these preliminary findings.

The effect of a locally adapted, secondary stroke risk factor self-management program on medication adherence among veterans with stroke/TIA.

We targeted stroke/transient ischemic attack (TIA) survivors to engage in self-management practices to manage secondary stroke risk factors. We conducted a randomized, regional pilot trial of a locally adapted, secondary stroke prevention program. We implemented the program at two Veterans Administration Medical Centers. Program sessions targeted stroke risk factor self-management. Specifically, we evaluated the effect of the program on the reach, implementation, and effectiveness on patient self-efficacy; stroke-specific, health-related quality of life; and medication adherence for the prevalent stroke risk factors: (1) diabetes, (2) hypertension, and (3) hyperlipidemia. Medication possession ratios were calculated to evaluate medication adherence using VA pharmacy benefits data pre (6 months prior) and post (6 months after) the stroke/TIA event. Based upon the literature standard of 80 % compliance rate, we dichotomized compliance and modeled the data using logistical regression. Final sample included 174 veterans with an acute stroke or TIA who were randomized to receive either the intervention (n = 87) or attention control program (n = 87). Patient self-efficacy and stroke-specific, health-related quality of life at 6 months did not significantly differ between groups. We found improvements in medication adherence within the intervention group. In the intervention group, the odds of compliance with diabetes medications post-stroke were significantly larger than the odds of compliance prior to the stroke (odds ratio = 3.45 (95 % CI = 1.08-10.96). For compliance to hypertension medications, the intervention group showed significantly greater odds of compliance post intervention than pre intervention (odds ratio = 3. 68 (95 % CI = 1.81-7.48). The control group showed no difference in compliance rates from baseline to follow-up. For adherence to hypercholesterolemia medications, both the intervention (odds ratio = 5.98 (95 % CI = 2.81-12.76) and control groups (odds ratio = 3.83 (95 % CI = 1.83-8.01), had significant increases in the odds of compliance to statin medications; however, the comparison of changes in log odds of compliance between these two groups showed that the increases were not significantly different. We observed within group improvements in medication adherence among those receiving a post-stroke risk factor self-management program suggesting that a self-management format may be feasible to enable adherence to prescribed medications to reduce secondary stroke risk after stroke in concordance with guideline care. Additional research is needed to enhance intervention components to improve effectiveness outcomes.

Rapid Aspiration Screening for Suspected Stroke: Part 2: Initial and Sustained Nurse Accuracy and Reliability.

OBJECTIVE: To determine registered nurses' (RNs') ability to obtain and maintain accurate procedural skills and reliable interpretation of the screening items under study to develop the Rapid Aspiration Screening for Suspected Stroke. DESIGN: Prospective, observation study. SETTING: A certified primary stroke center in a major metropolitan medical facility. PARTICIPANTS: RNs (N=15) were recruited and trained in the administration and interpretation of the screening items under study to develop the Rapid Aspiration Screening for Suspected Stroke. INTERVENTIONS: RNs completed a total of 239 screenings of patients admitted with suspected stroke over a 2-year period. RNs administered the swallowing screening items and interpreted the patient's response to each item. Independent of the RN, a speech-language pathologist simultaneously interpreted the response of the participant with stroke to each swallowing screening item. MAIN OUTCOME MEASURES: Reliability of the interpretation and accuracy of the administration of the swallowing screening items. RESULTS: The average accuracy rate for the administration of the Rapid Aspiration Screening for Suspected Stroke was 98.33%, with the overall accuracy rate for each procedural task ranging from 95.42% to 100%. For the specific swallowing screening items that formed the Rapid Aspiration Screening for Suspected Stroke, dysarthria and a positive sign after water swallow, reliability was high (k=.817). The accuracy rate for the administration and reliability of the interpretation of the swallowing screening items improved as RNs gained experience, and both were maximized at 20 screening opportunities. CONCLUSIONS: RNs demonstrate both excellent accuracy of procedural administration and reliability of interpretation of the items of the Rapid Aspiration Screening for Suspected Stroke. With feedback and repeated opportunities to practice, maintenance of skills is achievable.

Rapid Aspiration Screening for Suspected Stroke: Part 1: Development and Validation.

OBJECTIVE: To develop and validate a nurse-administered screening tool to identify aspiration risk in patients with suspected stroke. DESIGN: Validity study comparing evidence-based swallowing screening items with the videofluoroscopic swallowing study (VFSS) results. SETTING: A certified primary stroke center in a major metropolitan medical facility. PARTICIPANTS: Consecutive patients (N=250) admitted with suspected stroke. INTERVENTIONS: Patients were administered evidence-based swallowing screening items by nurses. A VFSS was completed within 2 hours of swallowing screening. MAIN OUTCOME MEASURES: Validity relative to identifying VFSS-determined aspiration for each screening item and for various combinations of items. RESULTS: Aspiration was identified in 29 of 250 participants (12%). Logistic regression revealed that age (P=.012), dysarthria (P=.001), abnormal volitional cough (P=.030), and signs related to the water swallow trial (P=.021) were significantly associated with aspiration. Validity was then determined on the basis of the best combination of significant items for predicting aspiration. The results revealed that age >70 years, dysarthria, or signs related to the water swallow trial (ie, cough, throat clear, wet vocal quality, and inability to continuously drink 90mL water) yielded 93% sensitivity and 98% negative predictive value. CONCLUSIONS: The final validated tool, Rapid Aspiration Screening for Suspected Stroke, is a valid nurse-administered tool to detect risk of aspiration in patients presenting with suspected stroke.

MCAM and LAMA4 Are Highly Enriched in Tumor Blood Vessels of Renal Cell Carcinoma and Predict Patient Outcome.

The structure and molecular signature of tumor-associated vasculature are distinct from those of the host tissue, offering an opportunity to selectively target the tumor blood vessels. To identify tumor-specific endothelial markers, we performed a microarray on tumor-associated and nonmalignant endothelium collected from patients with renal cell carcinoma (RCC), colorectal carcinoma, or colorectal liver metastasis. We identified a panel of genes consistently upregulated by tumor blood vessels, of which melanoma cell adhesion molecule (MCAM) and its extracellular matrix interaction partner laminin alpha 4 (LAMA4) emerged as the most consistently expressed genes. This result was subsequently confirmed by immunohistochemical analysis of MCAM and LAMA4 expression in RCC and colorectal carcinoma blood vessels. Strong MCAM and LAMA4 expression was also shown to predict poor survival in RCC, but not in colorectal carcinoma. Notably, MCAM and LAMA4 were enhanced in locally advanced tumors as well as both the primary tumor and secondary metastases. Expression analysis in 18 different cancers and matched healthy tissues revealed vascular MCAM as highly specific in RCC, where it was induced strongly by VEGF, which is highly abundant in this disease. Lastly, MCAM monoclonal antibodies specifically localized to vessels in a murine model of RCC, offering an opportunity for endothelial-specific targeting of anticancer agents. Overall, our findings highlight MCAM and LAMA4 as prime candidates for RCC prognosis and therapeutic targeting. Cancer Res; 76(8); 2314-26. ©2016 AACR.

Using Medical Mannequins to Train Nurses in Stroke Swallowing Screening.

Screening patients admitted with stroke symptoms for risk of aspiration is often the responsibility of registered nurses (RNs). Simulation technology has become a widely used evidence-based form of training for healthcare professionals. The purpose of this study was to determine if the use of medical simulation mannequins as a training component is feasible when training and evaluating nurses administering swallowing screenings to stroke patients. A total of 32 RNs were divided into one of two training groups: didactic training only or didactic training plus simulation. Acquisition of skills was assessed immediately post-training and compared between the groups revealing significant differences between simulation group and didactic-only group for interpretation (p = 0.01) and administration (p = 0.05) accuracies. Following training to 100 % accuracy for post-training baseline competency, maintenance of skills across participants was assessed three more times over 6 weeks with the third follow-up screening completed with a standardized patient (live patient actor). While interpretation performance at each subsequent trial never equaled the baseline 100 % post-training accuracy (p = 0.001), steady improvement in performance was observed with each follow-up assessment. For screening administration, no significant differences in skills were evident between post-training baseline competency and the 6-week follow-up (p = 0.269) further confirming improvement in skills over time. Extension of screening administration and interpretation skills to the standardized patient was evident. Findings indicate that simulation training using medical mannequins can be used to train and evaluate nurses for obtainment and maintenance of swallowing screening competency.

Speech Pathology Reliability for Stroke Swallowing Screening Items.

Swallowing screening is critical in rapid identification of risk of aspiration in patients presenting with acute stroke symptoms. Accuracy in judgments is vital for the success of the screening. This study examined speech-language pathologists' (SLPs) reliability in interpreting screening items. Swallowing screening was completed in 75 individuals admitted with stroke symptoms. Screening items evaluated were lethargy, dysarthria, wet voice unrelated to swallowing, abnormal volitional cough, and cough, throat clear, wet voice after swallowing, and inability to continuously drink with ingestion of 5 and 90 ml water. Two SLPs, each with more than 10 years of experience, made simultaneous independent judgments of the same observations obtained from the screening. Overall, generally high agreement was identified between the SLPs (k[SE] = 0.83[0.03]). Individual kappas ranged from 0.38 (fair) for non-swallowing wet voice to 0.95 (almost perfect) for cough after swallow, with one item omitted due to minimal variation. SLPs demonstrate high reliability in swallowing screening. Results, however, indicate some potential variability. Items associated with trial swallows had the highest reliability, whereas items related to judgments of speech and voice quality had the lowest. Although SLPs have dedicated training and ample opportunity to practice, differences in agreement are evident. Routine practice in hospital departments is recommended to establish and maintain sensitive perceptual discrimination. If other professionals are to provide swallowing screening, knowledge of SLPs' reliability levels must be considered when identifying screening items, creating education modules, and determining acceptable levels of agreement.

The golden hour Performing an acute ischemic stroke workup.

Ischemic stroke is a medical emergency resulting from an embolic or thrombotic occlusion of an intracranial artery. The purpose of this article is to provide acute care nurse practitioners a summary of recent updates on the rapid evaluation and workup for patient selection and treatment with I.V. fibrinolysis.

Hyperglycemia worsens outcome after rt-PA primarily in the large-vessel occlusive stroke subtype.

Hyperglycemia at the time of ischemic stroke has been associated with poorer outcomes. Preclinical literature suggests that hyperglycemia is an independent prognostic factor and the vasculature is more vulnerable to reperfusion injury. We applied a method to match subjects on important baseline factors to test whether, independent of stroke severity, stroke subtype influences the effect of hyperglycemia on outcome after recombinant tissue plasminogen activator (rt-PA). We reanalyzed the NINDS rt-PA dataset with respect to matching variables baseline NIHSS, age, and investigator-determined stroke subtypes small-vessel occlusive stroke (SVS), large-vessel occlusive stroke (LVS), and cardioembolic stroke (CES), above and below a glucose threshold of 150 mg/dl. Ninety-day outcomes were compared. Post hoc baseline matching was excellent in most cases. Hyperglycemia was associated with worsened functional outcome mostly in the LVS subtype with increased mortality in the placebo arm (15.3% mortality normoglycemia vs. 30.6% hyperglycemia; p = .046), worse functional outcome in the rt-PA arm (modified Rankin Score (mRS) 0-1; 46.3 vs. 22.0%; p = .034), and no improvement in functional outcome with rt-PA compared to placebo (mRS 0-1; 25% in both groups). Among hyperglycemic subjects, CES subjects showed significant improvement following rt-PA (p = .027). After matching for baseline severity, the influence of hyperglycemia on outcome was primarily in the LVS subtype, especially after rt-PA. This finding is consistent with a deleterious effect of hyperglycemia on ischemia/reperfusion of symptomatic large arteries. If confirmed, the particular vulnerability of the LVS subtype is important in understanding the role of stroke subtype in the mechanism of worsening and potential treatment of hyperglycemic stroke patients.

Accessibility, usability, and usefulness of a Web-based clinical decision support tool to enhance provider-patient communication around Self-management TO Prevent (STOP) Stroke.

This article reports redesign strategies identified to create a Web-based user-interface for the Self-management TO Prevent (STOP) Stroke Tool. Members of a Stroke Quality Improvement Network (N = 12) viewed a visualization video of a proposed prototype and provided feedback on implementation barriers/facilitators. Stroke-care providers (N = 10) tested the Web-based prototype in think-aloud sessions of simulated clinic visits. Participants' dialogues were coded into themes. Access to comprehensive information and the automated features/systematized processes were the primary accessibility and usability facilitator themes. The need for training, time to complete the tool, and computer-centric care were identified as possible usability barriers. Patient accountability, reminders for best practice, goal-focused care, and communication/counseling themes indicate that the STOP Stroke Tool supports the paradigm of patient-centered care. The STOP Stroke Tool was found to prompt clinicians on secondary stroke-prevention clinical-practice guidelines, facilitate comprehensive documentation of evidence-based care, and support clinicians in providing patient-centered care through the shared decision-making process that occurred while using the action-planning/goal-setting feature of the tool.

Percutaneous cryoablation of renal tumours: outcomes from 171 tumours in 147 patients.

OBJECTIVE: To evaluate the technical and oncological efficacy of an image-guided cryoablation programme for renal tumours. PATIENTS AND METHODS: A prospective analysis of technical and radiological outcomes was undertaken after treatment of 171 consecutive tumours in 147 patients. Oncological efficacy in a subset of 125 tumours in 104 patients with >6 months' radiological follow-up and a further subset of 62 patients with solitary, biopsy-proven renal carcinoma was also analysed. Factors influencing technical success, as determined by imaging follow-up, and complication rates were statistically analysed using a statistics software package and logistic regression analyses. RESULTS: No variables were found to predict subtotal treatment, although gender (P = 0.08), tumour size of >4 cm (P = 0.09) and central location of tumour (P = 0.07) approached significance. Upper pole location was the single variable that was found to predict complications (P = 0.006). Among the 104 patients (125 tumours), radiologically assessed at ≥6 months and with a mean radiological follow-up of 20.1 months, we found a single case of unexpected late local recurrence. CONCLUSION: Percutaneous image-guided cryoablation, at a mean of 20.1 months' follow-up, appears to provide a safe and effective treatment option with a low complication rate. Anteriorly sited tumours should not be considered a contraindication for percutaneous image-guided cryoablation.
