Impact of an electronic medical record system on emergency department discharge instructions for patients with hypertension.
Postgrad Med
PUBLISHED: 10-12-2013
Show Abstract
Hide Abstract
Uncontrolled hypertension is associated with significant patient morbidity and health care costs. Many patients evaluated in the emergency department (ED) do not regularly consult health care providers and have socioeconomic barriers to receiving primary care. Hypertension screening and counseling has been advocated as a routine part of ED care. Previous work has shown poor referral rates and education for ED patients presenting with elevated blood pressure (BP). We sought to determine whether implementation of an electronic medical record (EMR) would improve these rates.

NEXUS chest: validation of a decision instrument for selective chest imaging in blunt trauma.
JAMA Surg
PUBLISHED: 08-09-2013
Show Abstract
Hide Abstract
Chest radiography (chest x-ray [CXR] and chest computed tomography [CT]) is the most common imaging in blunt trauma evaluation. Unnecessary trauma imaging leads to greater costs, emergency department time, and patient exposure to ionizing radiation. OBJECTIVE To validate our previously derived decision instrument (NEXUS Chest) for identification of blunt trauma patients with very low risk of thoracic injury seen on chest imaging (TICI). We hypothesized that NEXUS Chest would have high sensitivity (>98%) for the prediction of TICI and TICI with major clinical significance.

A randomized clinical trial of the Health Evaluation and Referral Assistant (HERA): research methods.
Contemp Clin Trials
PUBLISHED: 02-14-2013
Show Abstract
Hide Abstract
The Health Evaluation and Referral Assistant (HERA) is a web-based program designed to facilitate screening, brief intervention, and referral to treatment (SBIRT) for tobacco, alcohol, and drug abuse. After the patient completes a computerized substance abuse assessment, the HERA produces a summary report with evidence-based recommended clinical actions for the healthcare provider (the Healthcare Provider Report) and a report for the patient (the Patient Feedback Report) that provides education regarding the consequences of use, personally tailored motivational messages, and a tailored substance abuse treatment referral list. For those who provide authorization, the HERA faxes the individuals contact information to a substance abuse treatment provider matched to the individuals substance use severity and personal characteristics, like insurance and location of residence (dynamic referral). This paper summarizes the methods used for a randomized controlled trial to evaluate the HERAs efficacy in leading to increased treatment initiation and reduced substance use. The study was performed in four emergency departments. Individual patients were randomized into one of two conditions: the HERA or assessment only. A total of 4269 patients were screened and 1006 participants enrolled. The sample was comprised of 427 tobacco users, 212 risky alcohol users, and 367 illicit drug users. Forty-two percent used more than one substance class. The enrolled sample was similar to the eligible patient population. The study should enhance understanding of whether computer-facilitated SBIRT can impact process of care variables, such as promoting substance abuse treatment initiation, as well as its effect on subsequent substance abuse and related outcomes.

A clinical decision rule that identifies patients at low risk for appendicitis may reduce the reliance on computed tomography (CT) for diagnosis. We seek to prospectively evaluate the accuracy of a low modified Alvarado score in emergency department (ED) patients with suspected appendicitis and compare the score to clinical judgment. We hypothesize that a low modified Alvarado score will have a sufficiently high sensitivity to rule out acute appendicitis.

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.

Hide Abstract
We report the case of a 62-year-old African American woman with poorly controlled diabetes who presented with the complaint of not being able to remove her stockings from her left foot. The patient had long-standing peripheral neuropathy from diabetes. Her physical examination in the emergency department was challenging because of extensive infection in her left lower extremity. Careful removal of the stockings resulted in the debridement of the lower third of her left leg and entire foot. Her laboratory findings were notable for a white blood cell count of 11.7 x 10(3) cells/mm(3) with 18% bands, an erythrocyte sedimentation rate of 100 mm/hour, and glycated hemoglobin of 11.5%. This case is unique in that the patient presented with both wet and dry gangrene of her lower extremities. We discuss the spectrum of infectious processes in diabetic foot infections and discuss the management of patients with necrotizing fasciitis.

The Dynamic Assessment and Referral System for Substance Abuse (DARSSA): development, functionality, and end-user satisfaction.
Drug Alcohol Depend
PUBLISHED: 05-22-2009
Show Abstract
Hide Abstract
The Dynamic Assessment and Referral System for Substance Abuse (DARSSA) conducts a computerized substance abuse assessment; prints personalized summary reports that include tailored substance abuse treatment referral lists; and, for individuals who provide authorization, automatically faxes their contact information to a "best match" substance abuse treatment provider (dynamic referral). After piloting the program and resolving problems that were noted, we enrolled a sample of 85 medical patients. The DARSSA identified 48 (56%) participants who were risky substance users, many of whom had not been identified during their routine medical assessment. Mean satisfaction scores for all domains ranged between "Good" to "Excellent" across patients, nurses, doctors, and substance abuse treatment providers. The median completion time was 13min. Of the 48 risky substance using participants, 20 (42%) chose to receive a dynamic referral. The DARSSA provides a user-friendly, desirable service for patients and providers. It has the potential to improve identification of substance abuse in medical settings and to provide referrals that would not routinely be provided. Future studies are planned to establish its efficacy at promoting treatment initiation and abstinence.

Smoking, cardiac symptoms, and an emergency care visit: a mixed methods exploration of cognitive and emotional reactions.
Emerg Med Int
Show Abstract
Hide Abstract
Emergency departments and hospitals are being urged to implement onsite interventions to promote smoking cessation, yet little is known about the theoretical underpinnings of behavior change after a healthcare visit. This observational pilot study evaluated three factors that may predict smoking cessation after an acute health emergency: perceived illness severity, event-related emotions, and causal attribution. Fifty smokers who presented to a hospital because of suspected cardiac symptoms were interviewed, either in the emergency department (ED) or, for those who were admitted, on the cardiac inpatient units. Their data were analyzed using both qualitative and quantitative methodologies to capture the individual, first-hand experience and to evaluate trends over the illness chronology. Reported perceptions of the event during semistructured interview varied widely and related to the individuals intentions regarding smoking cessation. No significant differences were found between those interviewed in the ED versus the inpatient unit. Although the typical profile was characterized by a peak in perceived illness severity and negative emotions at the time the patient presented in the ED, considerable pattern variation occurred. Our results suggest that future studies of event-related perceptions and emotional reactions should consider using multi-item and multidimensional assessment methods rated serially over the event chronology.

Measuring cognitive and affective constructs in the context of an acute health event.
Psychol Health Med
Show Abstract
Hide Abstract
The latest recommendations for building dynamic health behavior theories emphasize that cognitions, emotions, and behaviors--and the nature of their inter-relationships--can change over time. This paper describes the development and psychometric validation of four scales created to measure smoking-related causal attributions, perceived illness severity, event-related emotions, and intention to quit smoking among patients experiencing acute cardiac symptoms. After completing qualitative work with a sample of 50 cardiac patients, we administered the scales to 300 patients presenting to the emergency department for cardiac-related symptoms. Factor analyses, alpha coefficients, ANOVAs, and Pearson correlation coefficients were used to establish the scales reliability and validity. Factor analyses revealed a stable factor structures for each of the four constructs. The scales were internally consistent, with the majority having an alpha of >0.80 (range: 0.57-0.89). Mean differences in ratings of the perceived illness severity and event-related emotions were noted across the three time anchors. Significant increases in intention to quit at the time of enrollment, compared to retrospective ratings of intention to quit before the event, provide preliminary support for the sensitivity of this measure to the motivating impact of the event. Finally, smoking-related causal attributions, perceived illness severity, and event-related emotions correlated in the expected directions with intention to quit smoking, providing preliminary support for construct validity.

Over the past decade, clinicians have become increasingly reliant on computed tomography (CT) for the evaluation of patients with suspected acute appendicitis. To limit the radiation risks and costs of CT, investigators have searched for biomarkers to aid in diagnostic decision-making. We evaluated one such biomarker, calprotectin or S100A8/A9, and determined the diagnostic performance characteristics of a developmental biomarker assay in a multicenter investigation of patients presenting with acute right lower quadrant abdominal pain.

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.
