A Novel Silicon Device for the Packing of Cutaneous Abscesses.

BACKGROUND: Superficial skin abscesses are commonly encountered in emergency medicine practice. Standard treatment includes incision, drainage, and often packing with a gauze strip. The packing component of the procedure has several negative potential outcomes, is painful, and necessitates a return visit for removal. DISCUSSION: Here we report the first case in which a novel silicon packing device was utilized. The patient presented with a facial abscess, which was incised and drained. The novel device was inserted, and removed by the patient independently, without complication. Both patient and provider reported satisfaction with the novel procedure, and noted low pain scores. CONCLUSIONS: This device has the potential to replace traditional packing, and will require further study through a controlled trial to assess for safety and efficacy.

Institutional Pathways to Improve Care of Patients with Elevated Blood Pressure in the Emergency Department.

PURPOSE OF REVIEW: Hypertension (HTN) is the most prevalent cardiovascular disease and poses a major population level risk to long-term health outcomes. Despite this critical importance, and the widespread availability of effective and affordable medications, blood pressure (BP) remains uncontrolled in up to 50% of the diagnosed patients. This problem is exacerbated in communities with limited access to primary care, who often utilize hospital emergency departments (EDs) as their primary healthcare resource. Despite the ubiquity of patients presenting to EDs with severely elevated BP, a unified, evidence-based approach is not yet widely implemented, and both under- and overtreatment are common. The purpose of this review is to describe an approach towards institutional policy regarding asymptomatic HTN, in which we will translate the accepted principles of appropriate outpatient BP management to ED and inpatient settings. RECENT FINDINGS: Results from the recent SPRINT trial, and the subsequent publication of the American Heart Association updated guidelines for the treatment of HTN, significantly lower both the diagnostic threshold and the treatment goals for hypertensive patients. This change will drastically increase the proportion of patients presenting to EDs with newly diagnosed and uncontrolled HTN. Several recent studies emphasize the safety in outpatient management of patients with severely elevated BP in the absence of acute end-organ damage and, conversely, the long- and intermediate-term risk associated with these patients. System-based approaches, particularly those led by non-physicians, have shown the greatest promise in reducing population level uncontrolled HTN. Evidence-based approaches, such as those described in emergency medicine and cardiology society guidelines, can guide appropriate management of ED and inpatient BP elevations. Translating these patient oriented guidelines into institutional policy, and maintaining provider adherence, is a challenge across healthcare institutions. We present here several examples of successful policies developed and implemented by the authors. While brief inpatient and ED encounters cannot replace long-term outpatient care, they have the potential to serve as a crucial inlet to health care and an opportunity to optimize care.

Hot Topic: Global Burden of Treating Hypertension-What is the Role of the Emergency Department?

Hypertension (HTN) is the most common modifiable risk factor for cardiovascular disease (CVD) morbidity and mortality worldwide. Lower- and middle-income countries (LMICs) are projected to bear the vast majority of this disease burden, but local and regional health care delivery systems in these countries are ill equipped to meet this need. Emergency care is receiving increased recognition as a crucial component of public and community health. The rapid evolution of emergency care in LMICs provides a unique opportunity to develop innovative strategies, incorporating existing strengths of emergency departments, to address this paradigm shift in the disease burden associated with HTN on a global scale.

Access to care issues and the role of EDs in the wake of the Affordable Care Act.

CONTEXT: Americans who received public insurance under the Affordable Care Act use the emergency department (ED) more frequently than before they were insured. If newly enrolled patients cannot access primary care and instead rely on the ED, they may not enjoy the full benefits of health care services. OBJECTIVE: The objective of the study is to characterize reasons for ED utilization among American adults by insurance status and usual source of care. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional analysis of adult sample respondents to the 2013 National Health Interview Survey reporting 1 or more ED visits in the preceding 12 months. MAIN OUTCOMES AND MEASURES: Among American ED users that reported no usual source of care and who reported relying on the ED, 27.7% (95% confidence interval [CI], 23.6%-32.2%) and 35.1% (95% CI, 28.0%-43.0%) noted at least 1 issue of access and none of acuity as a reason for their last ED visit, as compared to 17.7% (95% CI, 16.3%-19.2%) among those with a stable usual source of care. CONCLUSIONS AND RELEVANCE: Although past research has shown that those who lack a stable usual source of care use the ED more often, this is the first population-level study to demonstrate their propensity for lack of access-based utilization. In the wake of the Affordable Care Act, EDs will need to evolve into outlets that service a wider range of health care needs rather than function in their current capacity, which is largely to address acute issues in isolation.

Anaphylactic reaction after ongoing exposure to hair glue: a novel case report.

BACKGROUND: Latex allergy is thought to be present in up to 6.5% of the general population, and can be much higher among those with chronic exposure. It is, however, uncommonly associated with severe anaphylactic reactions. Hair-care practices, such as the application of a hair weave, are a potential cause of latex-related anaphylaxis because the adhesives often contain natural rubber latex. CASE REPORT: We report the first case in the emergency medicine literature of successful treatment of a patient with airway compromise secondary to hair glue exposure. This case involved a 29-year-old woman who presented to the emergency department with severe angioedema and airway compromise. The patient had recently had an adhesive substance applied to her scalp for a hair weave placement. The patient did respond initially to antihistamine and alpha-adrenergic medication, however, because the allergen could not be removed, she relapsed, was subsequently intubated, and admitted to the intensive care unit. The latex-containing hair glue was removed over a period of several hours using an oil-based hair-conditioning product. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This unique and potentially lethal situation required innovative management. Successful resolution of this case required a high degree of cultural literacy leading to the correct diagnosis and treatment, and utilization of resources outside of the health care field. Clinicians treating patients in areas where similar hair-care practices are prevalent should be aware of this pathology, and consider similar management strategies.

Does Vitamin D Provide Added Benefit to Antihypertensive Therapy in Reducing Left Ventricular Hypertrophy Determined by Cardiac Magnetic Resonance?

BACKGROUND: Left ventricular hypertrophy (LVH) and vitamin D deficiency have been linked to hypertension (HTN) and cardiovascular disease, particularly in African Americans (AAs). Our objective was to determine if the addition of vitamin D to antihypertensive therapy would lead to greater regression of LV mass index (LVMI) as determined by cardiac magnetic resonance (CMR) after 1 year in vitamin D deficient AA patients with uncontrolled HTN and LVH. METHODS: This study was a randomized, double-blind, placebo-controlled, single-center study. AA patients with HTN (systolic blood pressure [BP] >160 mm Hg), increased LVMI, and vitamin D deficiency (<20 ng/ml) were randomized. All patients received antihypertensive therapy combined with biweekly 50,000 IU vitamin D3 (vitamin D group, n = 55) or placebo (placebo group, n = 58). RESULTS: At 1 year, there were no statistical differences between the vitamin D and placebo groups in LVMI (-14.1 ± 14.6 vs. -16.9 ± 13.1 g/m2; P = 0.34) or systolic BP (-25.6 ± 32.1 vs. -25.7 ± 25.6 mm Hg; P = 0.99) reduction, respectively. Serum vitamin D levels increased significantly in the vitamin D group compared with placebo (12.7 ± 2.0 vs. 1.8 ± 8.2 ng/ml; P < 0.001). CONCLUSIONS: In this high-risk cohort of AAs we did not find an association between vitamin D supplementation and differential regression of LVMI or reduction in systolic BP. However, our study suffered from a small sample size with low statistical power precluding a definitive conclusion on the therapeutic benefit of vitamin D in such patients.

Achieving the BpTRUth: emergency department hypertension screening and the Centers for Medicare & Medicaid Services quality measure.

In 2012, the Centers for Medicare & Medicaid Services (CMS) instituted a Physician Quality Reporting System measure for screening and referring patients with elevated blood pressure (BP). The aims of this study were to (1) assess the reliability of ED triage BP as a metric to establish when the CMS threshold (≥120/80 mm Hg), and other clinically relevant BP thresholds (≥140/90 and ≥160/100 mm Hg) have been met, using BP measured with a highly accurate device (BpTRU) in the emergency department as the gold standard; and (2) determine whether correct identification varies by gender, race, or triage acuity. Using the BpTRU, we calculated the proportion of patients whose triage BP accurately indicated a need for further referral and treatment for hypertension according to three suggested BP thresholds (≥120/80, ≥140/90, and ≥160/100 mm Hg). Of 354 patients, the median age was 39 years, 48.9% were women, and 66.4% were White. At the three suggested BP thresholds (≥120/80, ≥140/90, and ≥160/100 mm Hg), 66.1%, 74.0%, and 88.8% of patients were confirmed to meet the CMS threshold, respectively. There were no differences by gender, race, or triage acuity. Emergency department triage BP would reliably identify elevated BP using the CMS threshold in up to two-thirds of those without known hypertension.

Screening and Treatment for Subclinical Hypertensive Heart Disease in Emergency Department Patients With Uncontrolled Blood Pressure: A Cost-effectiveness Analysis.

OBJECTIVES: Poorly controlled hypertension (HTN) is extremely prevalent and, if left unchecked, subclinical hypertensive heart disease (SHHD) may ensue leading to conditions such as heart failure. To address this, we designed a multidisciplinary program to detect and treat SHHD in a high-risk, predominantly African American community. The primary objective of this study was to determine the cost-effectiveness of our program. METHODS: Study costs associated with identifying and treating patients with SHHD were calculated and a sensitivity analysis was performed comparing the effect of four parameters on cost estimates. These included prevalence of disease, effectiveness of treatment (regression of SHHD, reversal of left ventricular hypertrophy [LVH], or blood pressure [BP] control as separate measures), echocardiogram costs, and participant time/travel costs. The parent study for this analysis was a single-center, randomized controlled trial comparing cardiac effects of standard and intense (<120/80 mm Hg) BP goals at 1 year in patients with uncontrolled HTN and SHHD. A total of 149 patients (94% African American) were enrolled, 133 (89%) had SHHD, 123 (93%) of whom were randomized, with 88 (72%) completing the study. Patients were clinically evaluated and medically managed over the course of 1 year with repeated echocardiograms. Costs of these interventions were analyzed and, following standard practices, a cost per quality-adjusted life-year (QALY) less than $50,000 was defined as cost-effective. RESULTS: Total costs estimates for the program ranged from $117,044 to $119,319. Cost per QALY was dependent on SHHD prevalence and the measure of effectiveness but not input costs. Cost-effectiveness (cost per QALY less than $50,000) was achieved when SHHD prevalence exceeded 11.1% for regression of SHHD, 4.7% for reversal of LVH, and 2.9% for achievement of BP control. CONCLUSIONS: In this cohort of predominantly African American patients with uncontrolled HTN, SHHD prevalence was high and screening with treatment was cost-effective across a range of assumptions. These data suggest that multidisciplinary programs such as this can be a cost-effective mechanism to mitigate the cardiovascular consequences of HTN in emergency department patients with uncontrolled BP.

Trends in the Incidence of Hypertensive Emergencies in US Emergency Departments From 2006 to 2013.

BACKGROUND: The incidence of hypertensive emergency in US emergency departments (ED) is not well established. METHODS AND RESULTS: This study is a descriptive epidemiological analysis of nationally representative ED visit-level data from the Nationwide Emergency Department Sample for 2006-2013. Nationwide Emergency Department Sample is a publicly available database maintained by the Healthcare Cost and Utilization Project. An ED visit was considered to be a hypertensive emergency if it met all the following criteria: diagnosis of acute hypertension, at least 1 diagnosis indicating acute target organ damage, and qualifying disposition (admission to the hospital, death, or transfer to another facility). The incidence of adult ED visits for acute hypertension increased monotonically in the period from 2006 through 2013, from 170 340 (1820 per million adult ED visits overall) to 496 894 (4610 per million). Hypertensive emergency was rare overall, accounting for 63 406 visits (677 per million adult ED visits overall) in 2006 to 176 769 visits (1670 per million) in 2013. Among adult ED visits that had any diagnosis of hypertension, hypertensive emergency accounted for 3309 per million in 2006 and 6178 per million in 2013. CONCLUSIONS: The estimated number of visits for hypertensive emergency and the rate per million adult ED visits has more than doubled from 2006 to 2013. However, hypertensive emergencies are rare overall, occurring in about 2 in 1000 adult ED visits overall, and 6 in 1000 adult ED visits carrying any diagnosis of hypertension in 2013. This figure is far lower than what has been sometimes cited in previous literature.

Utility of Framingham risk score in urban emergency department patients with asymptomatic hypertension.

Hypertension (HTN) is the primary population-attributable risk for the development of heart failure (HF); a disease with devastating consequences particularly in urban centers where morbidity and mortality are more pronounced. The Framingham Risk Profile (FRP) is widely used to quantify risk for cardiovascular disease (CVD), but its applicability in an urban population who utilize the emergency department (ED) for primary care is unknown. The objective of this study is to evaluate FRP scores in ED patients with asymptomatic HTN and subclinical hypertensive heart disease (SHHD). This is a substudy of a prospective randomized clinical trial designed to evaluate optimal blood pressure (BP) targets. Eligible patients were screened with echocardiography for the presence of SHHD and FRP scores were calculated. One hundred forty-nine patients enrolled in the study, 133 (89.2%) of whom had detectable SHHD. Mean [SD] calculated FRP scores were statistically similar for patients with SHHD versus those without (general CVD: 20.2 [8.5] vs. 15.6 [8.7]; P = 0.13 and HF calibrated: 2.4 [1.0] vs. 1.8 [1.0]; P = 0.12) corresponding to a calculated risk of 15%-30% for subsequent development of CVD. The HF-specific risk score for patients with SHHD was 2.4, which equates to a 2.5% risk of HF development in 10 years. The FRP correctly identified those with SHHD as high-risk for general CVD but appeared to underestimate the likelihood of HF. Recalibration of the HF adjustment factor and inclusion of additional data elements such as echocardiography is needed to enhance applicability of the FRP in this setting.

Blood pressure control and perceived health status in African Americans with subclinical hypertensive heart disease.

The role of antihypertensive therapy in reducing the risk of cardiovascular complications such as heart failure is well established, but the effects of different blood pressure goals on patient-perceived health status has not been well defined. We sought to determine if adverse effects on perceived health status will occur with lower blood pressure goals or more intensive antihypertensive therapy. Data were prospectively collected as a part of a single center, randomized controlled trial designed to evaluate standard (Seventh Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure-compliant) versus intense (<120/80 mm Hg) blood pressure goals for patients with uncontrolled hypertension and subclinical hypertensive heart disease. Blood pressure management was open label, and health status was measured at 3-month intervals over 1 year of follow-up using the short-form (SF)-36. Mixed linear models were constructed for each of the SF-36 summary scores. One hundred twenty-three (mean age 49.4 ± 8.2; 65% female; 95.1% African American) patients were randomized, 88 of whom completed the protocol. With the exception of a decrease in perceived health transition, health status did not change significantly on repeat measurement. Lower blood pressure goals and more intensive antihypertensive therapy appear to be well tolerated with limited effects on patients' perception of health status.
