Effect Of In-Hospital Stroke Alert On Thrombolytic Therapy In Women
Full text linkBackground/Purpose. Stroke is the leading cause of disability in the United States. Women who have experienced a stroke have greater disability than men. Thrombolytic agents decrease adverse side effects of stroke by dissolving blood clots. Yet, women have 8% higher odds against being treated with a thrombolytic agent. Also, about 17% of stroke cases occur in-hospital. Therefore, the purpose of this study was to investigate the effects and associated variables of having an in-hospital stroke alert activation on outcomes in women admitted to the hospital for a separate condition.
Methods. Guided by the Model for Nursing Effectiveness Research, a retrospective observational study of 149 women participants was completed for a 4 year period. Study measures based on empirical evidence included the primary independent variable of in-hospital stroke alert, and confounding variables (patient characteristics, clinical conditions, and context of care) that are conceptually related to the primary outcome of thrombolytic therapy and secondary outcome of discharge status. Analysis included regression models and propensity score matching to isolate the treatment (in-hospital stroke alert) and outcome (thrombolytic therapy) while controlling the effects of other influential variables.
Results. In-hospital stroke alert was activated in 46 of 149 or 30.9% women and 15 of 149 or 10.1% of women received thrombolytic therapy. In-hospital stroke alert was significant (p \u3c .001) for women receiving thrombolytic therapy and significant to a home discharge status (p = .014). Age (p \u3c .001), marital status (p = .067), ethnicity (p \u3c .001), common (p = \u3c.001) and unique symptoms (p = .012), stroke risk factors were present (p \u3c.001), comorbid conditions
were present (p \u3c.001), Time Last Known Well (the time that the patient was without stroke symptoms) (p = .041), diagnostic imaging (p \u3c.001) were all significantly related to in-hospital stroke alert.
Discussion/Conclusions. Results from this study suggest that younger married women from non-Caucasian ethnic groups and women with risk factors or comorbid conditions are all at higher levels of late stroke symptom detection and no in-hospital stroke alert activation. Improved stroke detection in women with attention to barriers may improve in-hospital stroke alert activation and early treatment
Nurses Need Education on Women\u27s Unique Stroke Symptoms
No full textBackground: Stroke remains the third-leading cause of death and a major cause of disability in women. After a stroke, women have a 59% disability rate compared to 26% for men in the acute phase. Men and women share common stroke symptoms. However, women can also experience “unique” “atypical,” or “nontraditional” stroke symptoms. Early recognition of stroke is crucial to better outcomes, but despite the fact that nurses play a crucial role in identifying stroke symptoms and activating care early, information is lacking on nurse’s knowledge in recognizing stroke symptoms in women. Purpose: To examine nurse’s knowledge and confidence level in recognizing common and unique stroke symptoms in women. Methods: In this quantitative study, nurses were recruited via targeted social media platforms to complete an online survey about women and stroke. Nurses self-declared that they met eligibility criteria. A nurse was defined as an individual who holds a license, is legally permitted to practice, and holds the title of Registered Nurse, Advanced Practice Nurse (masters or doctorate), or Licensed Practical Nurse. Data were analyzed using descriptive statistics, independent t -tests, and one-way ANOVA. Results: 129 nurses completed the survey over four months. Nurses were 86% women with a mean age of 42 years, and 55% held advanced degrees. Over 80% identified the common stroke symptoms of stroke, and over 70% identified the additional stroke symptoms. However, less than 25% could identify unique stroke symptoms of women, including difficulty breathing or shortness of breath (7%), hallucination (11%). A majority of the nurses (76%) lacked the confidence to recognize stroke symptoms in women. Lower scores for common stroke symptom knowledge ( p =0.01), confidence ( p =0.01), and unique stroke symptoms in women confidence scores ( p =0.05) were observed in nurses with \u3c 20 years’ experience. Conclusions: Nurses lacked knowledge and confidence in correctly identifying unique stroke symptoms in women with nurses who had fewer years of professional experience fairing worse. Education targeted at nurses should include strategies to enhance their knowledge and confidence level in recognizing stroke symptoms unique to women
Effect of In-Hospital Stroke Alert on Thrombolytic Therapy in Women (Doctoral Dissertation)
No full textWomen and In-hospital Stroke Code Activation: Age, Ethnicity and Unique Symptoms Matter.
No full textBackground Women have worse stroke outcomes than men, and almost 17% of all stroke cases have symptom onset when admitted to the hospital for a separate condition.Objective The aim of this study was to investigate the distinctive factors that impact the activation of an in-hospital stroke code and outcomes in women who have a stroke while admitted to the hospital for a separate condition.Methods A retrospective observational propensity score study guided by the model for nursing effectiveness was used.Results In-hospital stroke code was activated in 46 of 149 or 30.9% of women and 15 of 149 or 10.1% of women received thrombolytic therapy. Activation of an in-hospital stroke code was significant (P \u3c .001) for women receiving thrombolytic therapy and significant to a home discharge status (P = .014). Age (P \u3c .001), ethnicity (P \u3c .001), common (P ≤ .001) and unique (P = .012) stroke symptoms, stroke risk factors (P \u3c .001), comorbid conditions (P \u3c .001), time last known well (P = .041), and diagnostic imaging (P \u3c .001) were all significantly related to activation of an in-hospital stroke code.Conclusions Activation of an in-hospital stroke is a key indicator for women to receive thrombolytic therapy and be discharged to home. Younger married women from non-Caucasian ethnic groups and women with stroke risk factors and comorbid conditions are at a greater risk for delayed stroke symptom detection and not having an in-hospital stroke code activated. Awareness of these factors that hinder early stroke detection in women is crucial to improving stroke treatment and outcomes in women
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
