Perception and Practice Among Emergency Medicine Health Care Providers Regarding Discharging Patients After Opioid Administration

Purpose

This study aimed to determine the current attitudes, perceptions, and practices of emergency medicine providers and nurses (RNs) regarding the discharge of adult patients from the emergency department (ED) after administration of opioid analgesics.

Resource utilization and health care charges associated with the most frequent ED users

Study objective

Emergency department (ED) visits have continued to rise, and frequent ED users account for up to 8% of all ED visits. Reducing visits by frequent ED users may be one way to help reduce health care costs. We hypothesize that frequent users have unique ED utilization patterns resulting in differences in health care charges.

Methods

We conducted a retrospective review of electronic medical records from an urban community teaching hospital for the year 2012 comparing the top 108 frequent ED users (> 12 visits/year) to a randomly selected group of 108 nonfrequent users (< 4 visits/year). We compared demographic characteristics, distance lived from the hospital, medical and psychiatric history, substance abuse history, diagnostic testing, disposition, and amount charged to the patient for each visit. We compared data using χ² for proportions and t test or Wilcoxon rank sum based on normality of the data.

Results

The top 108 frequent ED users accounted for 1922 visits (2.9%), whereas the 108 nonfrequent users accounted for 150 visits (0.2%), in 2012 (all ED visits n = 65,398). Frequent users were more often unemployed, have public insurance, have mental health conditions, use tobacco, have a greater number of allergies to medications, and live closer to the hospital (P < .01). Disposition and median charge per visit did not differ between frequent and nonfrequent users ($1220 vs $1280). The total charges of the frequent ED users’ visits were $10,465,216.07 versus $1,012,610.21 for nonfrequent users.

Conclusions

Frequent users have unique medical and social characteristics; however, disposition and visit charges did not differ from nonfrequent users.     

Methamphetamine-related Psychiatric Visits to an Urban Academic Emergency Department: An Observational Study

Background

Methamphetamine, a stimulant of abuse, is associated with a significant number of Emergency Department (ED) visits. Methamphetamine use may produce psychiatric symptoms including acute psychosis, depression, and anxiety disorders.

Study Objectives

To characterize psychiatric emergencies either directly or indirectly attributable to methamphetamine use in an urban academic ED.

Methods

We analyzed a database of patients determined to have an ED visit that was either methamphetamine related or non-methamphetamine related. We retrospectively reviewed the records of the subset of ED visits from this database with psychiatric diagnoses. We compared the characteristics of patients with methamphetamine-related psychiatric visits (MRPVs) and non-methamphetamine-related psychiatric visits (non-MRPVs).

Results

We identified 130 patients with MRPVs. This represented 7.6% (130 of 1709) of all psychiatric visits. Patients with MRPV, compared to non-MRPV patients, were younger (34.4 years vs. 39.1 years, respectively, p = 0.0005), more likely to be uninsured (55% vs. 37%, respectively, p = 0.001), and less likely to have a past history of depression (10% vs. 19%, respectively, p = 0.011). Many characteristics between the two groups (MRPV vs. non-MRPV) were similar: likelihood of patient being placed on a psychiatric hold; hospital charges; previous histories of psychiatric visits; and history of anxiety, bipolar disorder, or schizophrenia.

Conclusions

Methamphetamine may be related to a significant proportion (7.6%) of psychiatric ED visits. Furthermore, patients with methamphetamine-associated psychiatric visits are younger, have lower rates of depression, are more likely to be uninsured, and are less likely to have a substance abuse-related chief complaint than patients with non-methamphetamine-associated ED psychiatric visits.     

Violent behavior by emergency department patients with an involuntary hold status

Background

Violence against health care workers has been increasing. Health care workers in emergency departments (EDs) are highly vulnerable because they provide care for patients who may have mental illness, behavioral problems, or substance use disorders (alone or in combination) and who are often evaluated during an involuntary hold. Our objective was to identify factors that may be associated with violent behavior in ED patients during involuntary holds.

Patient Factors Associated with Failure to Diagnose Tuberculosis in the Emergency Department

Background

Emergency department (ED) presentation of pulmonary tuberculosis (TB) can be highly atypical and an ED visit might be the only health care interaction for high-risk patients.

Objective

Our objective was to identify patient factors associated with discharge without a diagnosis of TB during an infectious ED visit.

Methods

The study population consisted of 150 patients from 2000 to 2009 with 190 infectious ED visits. Patients were initially identified from the state registry of confirmed TB cases and epidemiological characteristics were identified prospectively during case investigation. A retrospective review was performed for clinical characteristics of visits dichotomized according to whether the diagnosis of TB was made during the ED visit.

Results

Analysis revealed that 77% of all infectious-patient visits ended with a diagnosis of TB. A TB diagnosis was more likely when patients presented with pulmonary or infectious chief complaints, endorsed cough, subjective fever, chills, dyspnea, previous TB infection, or had an abnormal lung examination or chest x-ray study. Patients were significantly less likely to be diagnosed with TB when they were unresponsive during clinical evaluation or when they reported a history of both homelessness and any substance abuse during the last year. In addition, these characteristics were independent predictors of nondiagnosis when traditional TB risk factors or abnormal vital signs were considered.

Conclusions

Patients with atypical presentations, as well as those who were unresponsive or reported a history of homelessness and substance abuse, were at greater risk for nondiagnosis of TB during an infectious ED visit.     

An Observational Study of Concomitant Use of Emerging Therapies and Denosumab or Zoledronic Acid in Prostate Cancer

Purpose

This observational study of oncologic clinical practices was designed to describe real-world patterns of use of emerging therapies (abiraterone acetate, cabazitaxel, enzalutamide, radium-223, sipuleucel-T) in patients with castration-resistant prostate cancer and to characterize their concomitant use with denosumab or zoledronic acid.

Prevalence of validated risk factors for developing atrial fibrillation-can we identify high-risk ED patients?

Objective

The aim of this study was to investigate whether emergency department (ED) patients who were newly diagnosed with atrial fibrillation (AF) displayed risk factors for incident AF on prior ED visits.

Methods

This was a secondary analysis of a retrospective cohort study of ED patients with symptomatic AF at a tertiary referral center. We selected patients who were newly diagnosed with AF between July 1, 2005, and August 31, 2008, and had at least 1 ED visit before their diagnosis. We calculated the Framingham Heart Study AF risk score for each visit by documenting the presence of the risk factors (age, sex, body mass index, systolic blood pressure, hypertension treatment, PR interval, and ages of clinically significant cardiac murmur and heart failure diagnosis).

Results

Of the 296 patients newly diagnosed with AF, 115 (39%) had at least 1 prior ED visit resulting in 454 ED visits for analysis. The median time from first to last visit was 4 years (interquartile range [IQR], 2.1-5.9). The median age was 66 years (IQR, 49-79 years). Home medications included antihypertensives in 81% of visits, and 60% of visits with available electrocardiograms had a PR interval of 160 milliseconds or more. Heart failure history was reported in 23% of visits. The median AF risk score was 8 (IQR, 4-10) corresponding to a 16% 10-year predicted risk.

Conclusions

Nearly 40% of patients diagnosed with new AF had previous ED visits and displayed validated risk factors for incident AF. The ED provides an opportunity to identify and educate these patients as well as refer them for primary prevention interventions.     

Hospitalizations and return visits after chronic obstructive pulmonary disease ED visits

Purpose

The aim of this study was to describe population-based patterns of chronic obstructive pulmonary disease (COPD)–related emergency department (ED) visits.

Methods

We analyzed all COPD-related ED visits made by North Carolina residents 45 years or older in 2008 to 2009 using statewide surveillance system data. Return visits were identified when patients returned to the same ED within 3 or 14 days of a prior COPD-related visit. We quantify the prevalence of hospitalization and return visits by age, sex, and payment method and describe ED disposition patterns.

Results

Nearly half (46.3%) of the 97?511 COPD-related ED visits resulted in hospital admission. The percent of visits preceded by another COPD-related visit within 3 and 14 days was 1.6% and 6.2%, respectively. Emergency department–related hospitalizations increased with age; there were no differences by sex. Hospitalizations were less likely for uninsured, Medicare, and Medicaid visits than for privately insured visits. In contrast, 3- and 14-day return visits were more likely to be uninsured, Medicare, and Medicaid visits than privately insured visits. Fourteen-day returns were more likely to be made by men. Return visits initially increased with age compared with the 45- to 49-year age group, then decreased steadily after age 65 years. When return visits were made, discharge at both visits was the most common disposition pattern. However, 33.7% of 3-day returns and 22.7% of 14-day returns were discharged at the first visit and hospitalized upon returning to the ED.

Conclusions

Chronic obstructive pulmonary disease–related hospital admissions and short-term return ED visits were common and varied by age and insurance status. Chronic obstructive pulmonary disease management remains a critical area for intervention and quality improvement.

Sex Differences in Hazard Ratio During Drug Treatment of Non–small-cell Lung Cancer in Major Clinical Trials: A Focused Data Review and Meta-analysis

Purpose

Understanding how sex impacts the efficacy of anticancer agents is a crucial step toward personalized and precision medicine. This review and meta-analysis evaluated sex differences in hazard ratios (HRs) of progression-free survival and overall survival in representative Phase III clinical trials of non–small-cell lung cancer (NSCLC).

Variation in outpatient emergency department utilization in Texas Medicaid: a state-level framework for finding “superutilizers”

Background

Very frequent outpatient emergency department (ED) use—so called “superutilization”—at the state level is not well-studied. To address this gap, we examined frequent ED utilization in the largest state Medicaid population to date.

Methods

Using Texas Medicaid (the third largest in the USA) claims data, we examined the variability in expenditures, sociodemographics, comorbidities, and persistence across seven levels of ED utilization/year (i.e., 1, 2, 3–4, 5–6, 7–9, 10–14, and ≥?15 visits). We classified visits into emergent and non-emergent categories using the most recent New York University algorithm.

Results

Thirty-one percent (n?=?346,651) of Texas Medicaid adult enrollees visited the ED at least once in 2014. Enrollees with ≥?3 ED visits accounted for 8.5% of all adult patients, 60.4% of the total ED visits, and 62.1% of the total ED expenditures. Extremely frequent ED users (≥?10 ED visits) represented <?1% of all users but accounted for 15.5% of all ED visits and 17.4% of the total ED costs. The proportions of ED visits classified as non-emergent or emergent, but primary care treatable varied little as ED visits increased. Overall, approximately 13% of ED visits were considered not preventable or avoidable.

Conclusions

The Texas Medicaid population has a substantial burden of chronic disease with only modest increases in substance use and mental health diagnoses as annual visits increase. Understanding the characteristics that lead to frequent ED use is vital to developing strategies and Medicaid policy to reduce high utilization.

     

Frequent attenders to the ED: patients who present with repeated asthma exacerbations

Background

Asthma has been reported as one of the main causes of frequent attendance to the emergency department (ED), and many of those visits are potentially preventable. Understanding the characteristics of frequent attender (FA) patients with asthmatic exacerbations will help to identify factors associated with frequent attendance and improve case management. The aim of this study is to describe the characteristics of FA who present multiple times to the ED for asthma exacerbations.

Methods

This study was a retrospective review of cases presented to Singapore General Hospital ED in 2010. Patients who attended the ED for 4 times or more with at least 1 visit attributable to asthma exacerbations in 2010 were included. They were then categorized as FA with multiple exacerbations (FAME) and those with fewer exacerbations.

Results

Of 105 616 ED patients, 155 patients attending the ED in 2010 were identified as FA with asthma, and 26 (17%) of these patients were classified as FAME, resulting in 213 visits (45% of total visits). Compared with FA with fewer exacerbations group, FAME were more likely to be men (P = .002), unemployed (P < .000), bad debtors (P = .045), substance abusers (P = .022), previously known to medical social workers (P = .002), and were found to spend a longer amount of time in the ED (> 6 hours) (P = .03).

Conclusion

We found that a small number of FAME patients accumulated a large number of ED visits and spent a significantly longer time in the ED. This group tended to be males with social, financial, and addiction problems.     

Utilization of head CT during injury visits to United States emergency departments: 2012–2015

Introduction

Studies have shown increasing utilization of head computed tomography (CT) imaging of emergency department (ED) patients presenting with an injury-related visit. Multiple initiatives, including the Choosing Wisely? campaign and evidence-based clinical decision support based on validated decision rules, have targeted head CT use in patients with injuries. Therefore, we investigated national trends in the use of head CT during injury-related ED visits from 2012 to 2015.

Characteristics and Trends of Emergency Department Visits in the United States (2010–2014)

Background

It is important that policy makers, health administrators, and emergency physicians have up-to-date statistics on the most common diagnoses of patients seen in the emergency department (ED).

Fetal Sex,Need for Insulin,and Perinatal Outcomes in Gestational Diabetes Mellitus: An Observational Cohort Study

Purpose

This was a prospective observational cohort study that aimed to determine whether fetal sex influences the maternal and fetal outcomes of gestational diabetes mellitus (GDM).

Short-term Unscheduled Return Visits of Adult Patients to the Emergency Department

Background

Emergency department (ED) crowding is a major international concern that affects patients and providers.

Study Objective

We describe the characteristics of patients who had an unscheduled related return visit to the ED and investigate its relation to ED crowding.

Methods

Retrospective medical record review of all unscheduled related ED return visits by patients older than 16 years of age over a 1-year period. The top quartile of ED occupancy rates was defined as ED crowding.

Results

Eight hundred thirty-seven patients (1.9%) made an unscheduled related return visit. Length of stay (LOS) at the ED for the index visit and the LOS for the return visit (5 h, 54 min vs. 6 h, 51 min) were significantly different, as were the percent admitted (11.6% vs. 46.1%). Of these patients, 85.1% and 12.0% returned due to persistence or a wrong initial diagnosis, of their initial illness, respectively, and 2.9% returned due to an adverse event related to the treatment initially received. Patients presented the least frequently with an alcohol-related complaint during the index visit (480 patients), but they had the highest number of unscheduled return visits (45 patients; 9.4%). Unscheduled related return visits were not associated with ED crowding.

Conclusion

Return visits impose additional pressure on the ED, because return patients have a significantly longer LOS at the ED. However, the rate of unscheduled return visits and ED crowding was not related. Because this parameter serves as an essential quality assurance tool, we can assume that the studied hospital scores well on this particular parameter.     

The impact of poison control centers on poisoning-related visits to EDs--United States, 2003

Purpose

This study analyzes the association between center usage rates and the rates of nonadmitted visits to emergency departments (EDs) for poisoning.

Basic Procedures

With a log-normal regression model, we analyzed the association between the number of human exposure calls per hospitalized poisoning patient and the number of nonhospitalized ED visits. The data were from 14 states at county level.

Main Findings

A 1% higher poison control center (PCC) human exposure call rate for unintentional poisoning is associated, but not necessarily causally, with a 0.18% lower ED visit rate (P < .0001). If the observed association is causative, 15.5 PCC human poison exposure calls prevent one nonadmitted ED visit, yielding a $205 net cost saving and a benefit-cost ratio of 1.4. The savings ignore any reduction in hospital admissions.

Principal Conclusions

Increased PCC exposure calls appear to be associated with reduced ED use for unintentional poisoning and appear to reduce net medical spending.
