Attitudes toward patients with sickle cell disease in a multicenter sample of emergency department providers.
Adv Emerg Nurs J

Show Abstract
Hide Abstract
Patients with sickle cell disease (SCD) often seek care in the emergency department (ED) for pain associated with vaso-occlusive crises. Research has shown that negative provider attitudes serve as a barrier to care in this patient population. Our aim was to validate a survey that measures attitudes toward SCD patients among ED providers (nurses and physicians) and to compare differences in attitude scores between provider types. We administered the general perceptions about Sickle Cell Disease Patients Scale, previously validated among internal medicine providers, and the Medical Condition Regard Scale (MCRS) to ED nurses and physicians from two EDs. A total of 215 surveys were returned (63% response rate, 200 with attitude items completed). Three subscales were identified: Negative Attitudes, Uneasiness With Care, and Positive Attitudes. Cronbach's ?s exceeded 0.81 for each subscale. Mean (SD) scores for the Negative, Uneasiness, and Positive subscales and MCRS were 61.5 (20.3), 66.1 (17.1), 41.2 (17.8), and 42.2 (8.9), respectively. Compared with physicians, nurses had significantly higher mean Negative Attitude scores and lower Uneasiness scores. A slightly modified version of the general perceptions about Sickle Cell Disease Patients Scale appears to be a valid measure of ED provider attitudes toward SCD patients. Among ED providers, this scale identified a dimension not observed in research with the original instrument among internal medicine providers. Provider attitudes influence patient-provider interactions and quality of care. The scale we present here has major clinical implications, particularly for advanced practice nurses, who can use the scale not only to assess providers' attitudes toward SCD patients but also to determine the effectiveness of tailored interventions to improve those attitudes.

Hide Abstract
Patients with sickle cell disease (SCD) often seek care in emergency departments (EDs) for severe pain. However, there is evidence that they experience inaccurate assessment, suboptimal care, and inadequate follow-up referrals. The aim of this project was to 1) explore the feasibility of applying a failure modes, effects and criticality analysis (FMECA) in two EDs examining four processes of care (triage, analgesic management, high risk/high users, and referrals made) for patients with SCD, and 2) report the failures of these care processes in each ED.

Show Abstract
Hide Abstract
The effect of chemical pretreatments on the color and carotenoid content of yellow discolored channel catfish fillets was studied. The color and carotenoid content of the fillets were analyzed by the L*a*b* color system and high-performance liquid chromatography, respectively. Untreated fillets turned more yellow and darker after 12-d storage. Sodium bicarbonate had a beneficial effect on reducing the degree of yellowness, but the fillets still turned darker after storage. Sodium bisulfite gave the best results with fillets becoming less yellow and brighter after storage. Ascorbic acid, butylated hydroxyanisole, citric acid, and sodium metabisulfite were not successful at reducing the discoloration. The sum of carotenoid contents of untreated fillets decreased significantly (P < 0.05) during storage as compared to the fresh fillets. However, the sum of the carotenoid contents of fillets treated by various chemicals was not significantly (P > 0.05) different from the fresh or untreated fillets. The appearance of catfish fillets may be improved during storage by pretreating with sodium bisulfite.

Treatment of hypertension in the emergency department.

Show Abstract
Hide Abstract
This review updates concepts of hypertension evaluation and management in patients presenting to the emergency department. It outlines the current challenges faced by emergency physicians in the identification and management of hypertensive patients: In spite of published emergency care guidelines, identification and referral rates remain low in patients presenting to the emergency department with moderate blood pressure (BP) elevations. In patients with severely elevated BP, the evaluation for acute end organ damage remains inconsistent and is symptom-based. Using current consensus guidelines, this review provides an algorithm for the management of the hypertensive emergency department patient. The final section of this review outlines management strategies for specific hypertensive emergencies.

Route visualization using detail lenses.
IEEE Trans Vis Comput Graph
PUBLISHED: 01-16-2010
Show Abstract
Hide Abstract
We present a method designed to address some limitations of typical route map displays of driving directions. The main goal of our system is to generate a printable version of a route map that shows the overview and detail views of the route within a single, consistent visual frame. Our proposed visualization provides a more intuitive spatial context than a simple list of turns. We present a novel multifocus technique to achieve this goal, where the foci are defined by points of interest (POI) along the route. A detail lens that encapsulates the POI at a finer geospatial scale is created for each focus. The lenses are laid out on the map to avoid occlusion with the route and each other, and to optimally utilize the free space around the route. We define a set of layout metrics to evaluate the quality of a lens layout for a given route map visualization. We compare standard lens layout methods to our proposed method and demonstrate the effectiveness of our method in generating aesthetically pleasing layouts. Finally, we perform a user study to evaluate the effectiveness of our layout choices.

Asymptomatic hypertension in the emergency department: a matter of critical public health importance.
Acad Emerg Med
PUBLISHED: 10-20-2009
Show Abstract
Hide Abstract
Asymptomatic hypertension (HTN) is commonly encountered in the emergency department (ED), but in most circumstances little is done about it. While many factors may contribute to this, the failure to recognize asymptomatic HTN as a public health problem is particularly important. Given the established long-term consequences of elevated blood pressure (BP), a reconsideration of methods that could enhance surveillance and intervention in the ED is needed. In this article, we discuss the relevant epidemiology of asymptomatic HTN and present a novel approach using a modified version of the Haddons matrix to systematically address the challenges that contribute to ineffective screening and suboptimal outcomes.

Importance of residency program web sites to emergency medicine applicants.
J Emerg Med
PUBLISHED: 05-05-2009
Show Abstract
Hide Abstract
Emergency Medicine (EM) residency program web sites are an important tool that programs use to attract applicants. However, there are only a few studies examining the aspects of a programs web site that are most important to EM applicants. We conducted a cross-sectional study of 142 prospective residency applicants interviewing for an EM position at one of three EM residency programs for the 2003 match. The survey demonstrated that almost all applicants researched EM programs online. The majority (71%) identified geographic location as the most important factor in applying to a specific program. Approximately 40% considered an easily navigated web site as very/moderately important to their application decision-making process. Rotation schedule was also important in applicant decision-making. The Internet is a significant source of information to the majority of applicants in EM. Online information from programs web sites, although not as significant as geography, influences an applicants choice of where to apply for a residency position. An easily navigated, complete web site may improve the recruitment of candidates to EM residency programs.

Emergency department patients self-report higher patient inertia, hopelessness, and harmful lifestyle choices than community counterparts.
J Clin Hypertens (Greenwich)
Show Abstract
Hide Abstract
Patient inertia is defined as an individuals failure to take responsibility for proactive lifestyle change and health conditions including hypertension. Generalized and hypertension-specific patient inertia factors were compared in 110 patients (48% women; 52% African American) from a Forsyth County, NC, emergency department (ED) and 104 community members (79% women; 70% African American) using the patient inertia-facilitated survey Patient Inertia-36. Statistically, more ED than community participants added salt to food at the table and consumed fast foods 5 to 7 days a week. ED patients agreed less often with health literacy questions about salt and BP. Hypertension associated Patient inertia questions asked of 45 ED and 40 community participants with a personal history of hypertension revealed a statistically higher sense of hopelessness surrounding blood pressure management in ED participants. Past BP control experiences of family members had statistically greater impact on community participants regarding their own BP control. Using a logistic regression model, advancing age and being surveyed in the ED were correlated with hopelessness towards BP control. ED patients make unhealthier diet choices and possess heightened generalized and hypertension-specific patient inertia including hopelessness towards controlling their BP that increases with age. These factors may contribute to this populations poor BP control, particularly self-efficacy barriers.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
