Preventive Cardiovascular Care for Hypercholesterolemia in US Emergency Departments: A National Missed Opportunity

BACKGROUND

Hypercholesterolemia (HCL) affects nearly half of Emergency Department (ED) patients who present with possible acute coronary syndrome (ACS). However, it is unknown whether US ED providers obtain lipid panels, calculate 10-year atherosclerotic cardiovascular disease (ASCVD) risk, and prescribe cholesterol-lowering medications for these patients.

METHODS

We conducted a nationwide cross-sectional ED survey from April 18, 2023, to May 12, 2023. An electronic survey assessing current preventive HCL care practices for patients being evaluated for ACS. A convenience sample was obtained by sharing the survey with ED medical directors, chairs, and senior leaders using emergency medicine professional organization listservs and snowball sampling. Responding EDs were categorized as being associated with an academic medical center (AMC) or not (non-AMC).

RESULTS

During the 4-week study period, 110 EDs (50 AMC and 60 non-AMC EDs) across 39 states responded. Just 1.8% (2/110) stated that their providers obtain a lipid panel on at least half of patients with possible ACS and only one ED (0.9%) responded that its providers calculate 10-year ASCVD risk and prescribe cholesterol medication for the majority of eligible patients. Most reported never obtaining lipid panels (60.9%, 67/110), calculating 10-year ASCVD risk (55.5%, 61/110), or prescribing cholesterol-lowering medications (52.7%, 58/110).

CONCLUSIONS

The vast majority of US ED providers do not provide preventive cardiovascular care for patients presenting with possible ACS. Most ED providers do not evaluate for HCL, calculate ASCVD risk, or prescribe cholesterol-lowering medications for these patients.

Emergency Department Observation Unit Patients Want Evaluation and Treatment for Hypercholesterolemia: A Health Belief Model Study

BACKGROUND

Hypercholesterolemia (HCL) is common among emergency department (ED) and ED observation unit (EDOU) patients with chest pain but is not typically addressed in these settings. The objective of this study was to assess patient attitudes towards EDOU-based HCL care using the Health Belief Model.

METHODS

We conducted a cross-sectional survey study among 100 EDOU patients ≥18 years-old evaluated for chest pain in the EDOU of a tertiary care center from September 1, 2020, to November 01, 2021. Five-point Likert-scale surveys were used to assess each Health Belief Model domain: Cues to Action, Perceived Susceptibility, Perceived Barriers, Perceived Self-Efficacy, and Perceived Benefits. Responses were categorized as agree or do not agree.

RESULTS

The participants were 49.0% (49/100) female, 39.0% (39/100) non-white, and had a mean age of 59.0 ± 12.4 years. Most (83.0% [83/100, 95% confidence interval (CI), 74.2%-89.8%]) agreed the EDOU is an appropriate place for HCL education and 52.0% (52/100, 95% CI, 41.8%-62.1%) were interested in talking with their EDOU care team about HCL. Regarding Perceived Susceptibility, 88.0% (88/100, 95% CI, 80.0%-93.6%) believed HCL to be bad for their health, while 41.0% (41/100, 95% CI, 31.3%-51.3%) believed medication costs could be a barrier. For Perceived Self-Efficacy, 76.0% (76/100, 95% CI, 66.4%-84.0%) were receptive to taking medications. Overall, 95.0% (95/100, 95% CI, 88.7%-98.4%) believed managing HCL would benefit their health.

CONCLUSIONS

This Health Belief Model-based survey indicates high patient interest in EDOU-initiated HCL care. Patients reported high rates of Perceived Susceptibility, Self-Efficacy, and Benefits and a minority found HCL therapy costs a barrier.

Effectiveness of an Emergency Department-Based Machine Learning Clinical Decision Support Tool to Prevent Outpatient Falls Among Older Adults: Protocol for a Quasi-Experimental Study

BACKGROUND

Emergency department (ED) providers are important collaborators in preventing falls for older adults because they are often the first health care providers to see a patient after a fall and because at-home falls are often preceded by previous ED visits. Previous work has shown that ED referrals to falls interventions can reduce the risk of an at-home fall by 38%. Screening patients at risk for a fall can be time-consuming and difficult to implement in the ED setting. Machine learning (ML) and clinical decision support (CDS) offer the potential of automating the screening process. However, it remains unclear whether automation of screening and referrals can reduce the risk of future falls among older patients.

OBJECTIVE

The goal of this paper is to describe a research protocol for evaluating the effectiveness of an automated screening and referral intervention. These findings will inform ongoing discussions about the use of ML and artificial intelligence to augment medical decision-making.

METHODS

To assess the effectiveness of our program for patients receiving the falls risk intervention, our primary analysis will be to obtain referral completion rates at 3 different EDs. We will use a quasi-experimental design known as a sharp regression discontinuity with regard to intent-to-treat, since the intervention is administered to patients whose risk score falls above a threshold. A conditional logistic regression model will be built to describe 6-month fall risk at each site as a function of the intervention, patient demographics, and risk score. The odds ratio of a return visit for a fall and the 95% CI will be estimated by comparing those identified as high risk by the ML-based CDS (ML-CDS) and those who were not but had a similar risk profile.

RESULTS

The ML-CDS tool under study has been implemented at 2 of the 3 EDs in our study. As of April 2023, a total of 1326 patient encounters have been flagged for providers, and 339 unique patients have been referred to the mobility and falls clinic. To date, 15% (45/339) of patients have scheduled an appointment with the clinic.

CONCLUSIONS

This study seeks to quantify the impact of an ML-CDS intervention on patient behavior and outcomes. Our end-to-end data set allows for a more meaningful analysis of patient outcomes than other studies focused on interim outcomes, and our multisite implementation plan will demonstrate applicability to a broad population and the possibility to adapt the intervention to other EDs and achieve similar results. Our statistical methodology, regression discontinuity design, allows for causal inference from observational data and a staggered implementation strategy allows for the identification of secular trends that could affect causal associations and allow mitigation as necessary.

Rarely tested or treated but highly prevalent: Hypercholesterolemia in emergency department observation unit patients with chest pain

BACKGROUND

Hypercholesterolemia (HCL) is common among Emergency Department (ED) patients with chest pain but is typically not addressed in this setting. This study aims to determine whether a missed opportunity for Emergency Department Observation Unit (EDOU) HCL testing and treatment exists.

METHODS

We conducted a retrospective observational cohort study of patients ≥18 years old evaluated for chest pain in an EDOU from 3/1/2019-2/28/2020. The electronic health record was used to determine demographics and if HCL testing or treatment occurred. HCL was defined by self-report or clinician diagnosis. Proportions of patients receiving HCL testing or treatment at 1-year following their ED visit were calculated. HCL testing and treatment rates at 1-year were compared between white vs. non-white and male vs. female patients using multivariable logistic regression models including age, sex, and race.

RESULTS

Among 649 EDOU patients with chest pain, 55.8% (362/649) had known HCL. Among patients without known HCL, 5.9% (17/287, 95% CI 3.5-9.3%) had a lipid panel during their index ED/EDOU visit and 26.5% (76/287, 95% CI 21.5-32.0%) had a lipid panel within 1-year of their initial ED/EDOU visit. Among patients with known or newly diagnosed HCL, 54.0% (229/424, 95% CI 49.1-58.8%) were on treatment within 1-year. After adjustment, testing rates were similar among white vs. non-white patients (aOR 0.71, 95% CI 0.37-1.38) and men vs. women (aOR 1.32, 95% CI 0.69-2.57). Treatment rates were similar among white vs. non-white (aOR 0.74, 95% CI 0.53-1.03) and male vs. female (aOR 1.08, 95% CI 0.77-1.51) patients.

CONCLUSIONS

Few patients were evaluated for HCL in the ED/EDOU or outpatient setting after their ED/EDOU encounter and only 54% of patients with HCL were on treatment during the 1-year follow-up period after the index ED/EDOU visit. These findings suggest a missed opportunity to reduce cardiovascular disease risk exists by evaluating and treating HCL in the ED or EDOU.

Chest pain observation unit: A missed opportunity to initiate smoking cessation therapy

BACKGROUND

Emergency Department Observation Unit (EDOU) patients with chest pain have a high prevalence of smoking, a key cardiovascular disease risk factor. While in the EDOU, there is an opportunity to initiate smoking cessation therapy (SCT), but this is not standard practice. This study aims to describe the missed opportunity for EDOU-initiated SCT by determining the proportion of smokers who receive SCT in the EDOU and within 1-year of EDOU discharge and to evaluate if SCT rates vary by race or sex.

METHODS

We performed an observational cohort study of patients ≥18 years old being evaluated for chest pain in a tertiary care center EDOU from 3/1/2019-2/28/2020. Demographics, smoking history, and SCT were determined by electronic health record review. Emergency, family medicine, internal medicine, and cardiology records were reviewed to determine if SCT occurred within 1-year of their initial visit. SCT was defined as behavioral interventions or pharmacotherapy. Rates of SCT in the EDOU, 1-year follow-up period, and the EDOU through 1-year of follow-up were calculated. SCT rates from the EDOU through 1-year were compared between white vs. non-white and male vs. female patients using a multivariable logistic regression model including age, sex, and race.

RESULTS

Among 649 EDOU patients, 24.0% (156/649) were smokers. These patients were 51.3% (80/156) female and 46.8% (73/156) white, with a mean age of 54.4 ± 10.5 years. From the EDOU encounter through 1-year of follow-up, only 33.3% (52/156) received SCT. In the EDOU, 16.0% (25/156) received SCT. During the 1-year follow-up period, 22.4% (35/156) had outpatient SCT. After adjusting for potential confounders, SCT rates from the EDOU through 1-year were similar among whites vs. non-whites (aOR 1.19, 95% CI 0.61-2.32) and males vs. females (aOR 0.79, 95% CI 0.40-1.56).

CONCLUSIONS

SCT was rarely initiated in the EDOU among chest pain patients who smoke and most patients who did not receive SCT in the EDOU never received SCT at 1-year of follow-up. Rates of SCT were similarly low among race and sex subgroups. These data suggest an opportunity exists to improve health by initiating SCT in the EDOU.

Evaluation of a pilot emergency department linkage to care program for patients previously diagnosed with Hepatitis C

There is a significant number of Emergency Department (ED) patients with known chronic hepatitis C virus (HCV) infection who have not been treated with directly acting antivirals. We implemented a pilot ED-based linkage-to-care program to address this need and evaluated the impact of the program using the HCV Care Continuum metrics. Between March 2015 and May 2016, dedicated patient care navigators identified HCV RNA-positive patients in an urban ED and offered expedited appointments with the on-site viral hepatitis clinic. Patient demographics and care continuum outcomes were abstracted from the EMR and analysed to determine significant factors influencing linkage-to-care (LTC) and treatment initiation rates. The ED linkage-to-care program achieved a 43% linkage-to-care rate (165/384), 22% treatment rate (84/384) and 16% sustained virologic response rate (63/384). Significant associations were found between linkage-to-care and increasing age (OR = 1.03), Medicare insurance (OR = 2.21) and having a primary care physician (PCP) (OR = 4.03). For patients who were linked, the odds of initiating treatment were also positively significantly associated with increasing age (OR = 1.04) and having a PCP (OR = 2.77). For patients who initiated treatment, the odds of sustained virologic response were marginally associated with having a PCP (OR = 4.92).Our ED linkage-to-care program utilized care coordination to successfully link nearly half of approached HCV RNA-positive patients to care. This design can be feasibly replicated by other EDs given limited non-clinical training required for linkage-to-care staff. Adoption of similar programs in other EDs may improve the rates of LTC and treatment initiation for previously diagnosed HCV patients.

Barriers to implementation of pediatric emergency department interventions for parental tobacco use and dependence: a qualitative study using the theoretical domains framework

Background

Pediatric emergency department (PED) and urgent care (UC) professionals can play a key role in delivering evidence-based guidelines to address parental tobacco use and child tobacco smoke exposure (TSE). Understanding PED/UC professionals’ perceptions regarding these guidelines is the first step in developing and implementing a TSE screening and counseling intervention in these settings. This study aimed to use the theoretical domains framework (TDF) to identify current screening and counseling behaviors of PED/UC professionals related to parental tobacco use and child TSE, and determine barriers and enablers that influence these behaviors.

Methods

Semi-structured, focused interviews were conducted with 29 actively practicing PED/UC clinical staff who worked at one large, Midwestern children’s hospital. The interview guide was informed by the TDF and included open-ended questions. Content analysis of interview transcripts was guided by the TDF. Nurses, physicians, and healthcare administrators were assessed overall and by group membership to ensure each group was represented based on their varying PED/UC roles.

Results

Fifty-one percent were nurses, 38% were physicians, and 11% were healthcare administrators. Most PED/UC professionals did not currently follow the guidelines, but perceived addressing parental tobacco use as part of their role. All 14 TDF domains were identified by nurses, physicians, and administrators in relation to counseling for parental tobacco use and child TSE. Domains with the most sub-themes were (1) knowledge: lack of knowledge about tobacco counseling, including implementing counseling, cessation resources/referrals, and thirdhand smoke; (2) beliefs about capabilities: not comfortable counseling parents, easier to discuss with parents who are receptive and to ask and advise when patients have a TSE-related complaint, and more likely to discuss if there were resources/referrals; and (3) environmental context and resources: barriers include lack of time, training, and resources and referral information to give to parents, and an enabler is using TSE-related complaints as a context to offer counseling.

Conclusions

Study findings provide a strong foundation for developing and implementing clinical practice guidelines regarding parental tobacco use and child TSE in the PED/UC setting. Future intervention development will address all TDF domains and test the implementation of the intervention in the PED/UC setting.

Variation in Participation in Nurse-Driven Emergency Department Hepatitis C Screening

Emergency departments (EDs) are an important potential site for public health screening programs, although implementation of such programs can be challenging. Potential barriers include system-level issues (e.g., funding and time pressures) and individual provider-level issues (e.g., awareness and acceptance). This cross-sectional evaluation of a nurse-driven, triage-based hepatitis C virus (HCV) screening program in an urban, academic ED assessed variation in nurse participation from April to November 2017. For this program, electronic health record (EHR) prompts for HCV screening were integrated into nurses' triage workflow. Process measures evaluating HCV screening participation were abstracted from the EHR for all ED encounters with patient year of birth between 1945 and 1965. Registered nurses who routinely worked in triage and were full-time employees throughout the study period were included for analysis. The primary outcome was the proportion of eligible ED encounters with completed HCV screening, by nurse. Of 14,375 ED encounters, 3,375 (23.5%, 95% confidence interval [CI]: 22.8, 24.2) had completed HCV screening and 1,408 (9.8%, 95% CI: 3.9, 10.3) had HCV screening EHR sections opened by the triage nurse but closed without action; the remainder of encounters had no activity in HCV screening EHR sections. Among the 93 eligible nurses, 22 nurses (24%, 95% CI: 16, 34) completed HCV screening for more than 70% of encounters, whereas 10 nurses (11%, 95% CI: 6, 19) never completed HCV screening. The proportion of eligible encounters with completed HCV screening was 11.0% higher (95% CI: 9.8, 12.6) for encounters seen between 7 a.m. and 7 p.m. than between 7 p.m. and 7 a.m. (27.5% and 16.3%, respectively). In conclusion, wide variation in individual nurse participation in HCV screening suggests individual-level barriers are a more significant barrier to ED screening than previously recognized. Implementation research should expand beyond questions of resource availability and procedural streamlining to evaluate and address staff knowledge, beliefs, attitudes, and motivation.

Case Series of Patients with Opioid Use Disorder and Suicidal Ideation Treated with Buprenorphine

Introduction

Buprenorphine benefits patients with opioid use disorder (OUD) in the emergency department (ED), but its efficacy for OUD patients with suicidal ideation (SI) in the ED is unknown.

Case Series

We present a case series of 14 OUD patients with SI who were given buprenorphine and a referral to outpatient substance use treatment in the ED. All experienced SI resolution, engaged with outpatient services, and remained in outpatient substance use treatment 30 days after ED discharge.

Conclusion

Our data provide evidence for the feasibility of starting buprenorphine in OUD patients with SI in the ED, and suggest that buprenorphine may be useful in helping to resolve SI for these patients. Future research with larger samples is needed.

Remote area nursing: best practice or paternalism in action? The importance of consumer perspectives on primary health care nursing practice in remote communities

This paper reports on a study that aimed to understand how remote area nurses implemented primary health care principles in the Australian remote health care setting. Twenty-four Registered Nurses and Nurse Practitioners who worked in remote health services without inpatient facilities were interviewed using constructivist grounded theory methods. Findings revealed that nurses in this study aimed to practice in a way that was guided by Indigenous empowerment and social justice. However, some nurses questioned elements of their practice such as 'chasing' people for appointments or routine screening required by clinical guidelines that may not reflect the values of Indigenous peoples. Nurses expressed concern that they may be reinforcing past colonising practices and their actions may be considered paternalistic rather than empowering. Nurses in this study wanted to develop partnerships and provide nursing care that aligned with the health and wellbeing expectations of communities. However, ways of communicating the needs of communities and the development of partnerships between health providers and communities need to be developed. The present study calls for further research from the perspective of remote community members in order to develop ways of sharing knowledge about health and wellbeing between remote area nurses and communities.

Identifying opportunities for health promotion and intervention in the ED

BACKGROUND

ED staff assess patients with modifiable risk factors for acute and chronic illness. Health promotion interventions delivered in the ED have been advocated for these patients. The engagement of staff is essential to provide effective screening and brief interventions for patients. This survey aimed to assess if staff support the ED as an environment for health promotion.

METHODS

A multicentre, structured survey was conducted in four EDs in Scotland from 2017 to 2018. Physician and nursing staff at two teaching and two district general hospitals (n=423) were study eligible and offered a multicomponent survey. Outcomes measured included perceived barriers to practice and risk factor specific ED interventions.

RESULTS

Of the 283 respondents, 116 (41%) were physicians and 167 (59%) were nurses. More physicians (86.1%) than nurses (49.7%) reported offering health promotion interventions. Time constraints and a lack of health promotion infrastructure in the ED were cited as challenges to intervention delivery. Staff believed that alcohol (n=170/283, 60.1%) and drug misuse (n=173/283, 61.1%) were more appropriately managed in the ED than primary care. ED staff believed same day brief interventions were more appropriate when alcohol/drug misuse and smoking were directly related to ED presentations.

DISCUSSION AND CONCLUSIONS

Staff support the concept of the ED as a potential environment for offering health promotion interventions. ED physicians and nurses have different perspectives on the delivery of health promotion. The role of the ED in health promotion is likely to be multimodal and dependant on the reason for ED attendance.

Child tobacco smoke exposure and healthcare resource utilization patterns

BACKGROUND

The objective was to examine the relationship between healthcare resource utilization patterns in tobacco smoke-exposed children (TSE group) compared with unexposed children (non-TSE group).

METHODS

We matched 380 children in the TSE group with 1140 children in the non-TSE group based on child age, sex, race, and ethnicity using propensity scores. Healthcare resource utilization variables included respiratory-related procedures, diagnostic testing, disposition, and medications. Logistic and linear regression models were built.

RESULTS

Child mean age was 4.9 (SD = 0.1) years, 50.5% were female, 55.5% black, and 73.2% had public insurance/self-pay. Compared to the non-TSE group, the TSE group was at increased odds to have the following performed/obtained: nasal bulb suctioning, infectious diagnostic tests, laboratory tests, and radiologic tests. The TSE group was more likely to be admitted to the hospital, and more likely to receive steroids and intravenous fluids during their visit. Among asthmatics, the TSE group was more likely to receive steroids, albuterol, or ipratropium alone, or a combination of all three medications during their visit, and be prescribed albuterol alone or steroids and albuterol.

CONCLUSION

Tobacco smoke-exposed children are more likely to have higher resource utilization patterns, highlighting the importance of screening and providing TSE prevention and remediation interventions.

IMPACT

Tobacco smoke exposure may affect the healthcare resource utilization patterns of children. Evidence is lacking concerning these associations among the highly vulnerable pediatric emergency department patient population. This study examined the association between tobacco smoke exposure and healthcare resource utilization patterns among pediatric emergency department patients. Tobacco smoke exposure increased the risk of pediatric patients having respiratory-related procedures, respiratory-related and non-respiratory-related testing, medications administered during the pediatric emergency department visit, and medications prescribed for home administration. Tobacco smoke-exposed patients were more likely to be admitted to the hospital compared to unexposed patients.

Emergency department targeted screening for hepatitis C does not improve linkage to care

BACKGROUND

Hepatitis C virus (HCV) infection is a leading cause of chronic liver disease worldwide. New treatments for HCV revolutionized management and prompted the world health organization to set the goal of viral elimination by 2030. These developments strengthen the need for HCV screening in order to identify asymptomatic carriers prior to development of chronic liver disease and its complications. Different screening strategies have been attempted, most targeting high-risk populations. Previous studies focusing on patients arriving at emergency departments showed a higher prevalence of HCV compared to the general population.

AIM

To identify previously undiagnosed HCV carriers among high risk emergency room attendees and link them to care for anti-viral treatment.

METHODS

In this single center prospective study, persons visiting the emergency department in an urban hospital were screened by a risk factor-specific questionnaire. The risk factors screened for were exposure to blood products or organ transplantation before 1992; origins from countries with high prevalence of HCV; intravenous drug use; human immunodeficiency virus carriers; men who have sex with men; those born to HCV-infected mothers; prior prison time; and chronic kidney disease. Those with at least one risk factor were tested for HCV by serum for HCV antibodies, a novel oral test from saliva (OraQuick^®) or both.

RESULTS

Five hundred and forty-one participants had at least one risk factor and were tested for HCV. Eighty four percent of all study participants had only one risk factor. Eighty five percent of participants underwent OraQuick^® testing, 34% were tested for serum anti-HCV antibodies, and 25% had both tests. 3.1% of patients (17/541) had a positive result, compared to local population incidence of 1.96%. Of these, 82% were people who inject drugs (current or former), and 64% served time in prison. One patient had a negative HCV-RNA, and two patients died from non-HCV related reasons. On review of past medical records, 12 patients were found to have been previously diagnosed with HCV but were unaware of their carrier state. At 1-year follow-up none of the remaining 14 patients had completed HCV-RNA testing, visited a hepatology clinic or received anti-viral treatment.

CONCLUSION

Targeted high-risk screening in the emergency department identified undiagnosed and untreated HCV carriers, but did not improve treatment rates. Other strategies need to be developed to improve linkage to care in high risk populations.

Screening, Counseling, and Health Care Utilization Among a National Sample of Adolescent Smokers

Our objective was to assess the association between cigarette smoking and tobacco use screening and advising to quit use by a clinician among adolescents nationwide. We also examined the relationships between smoking and health-related indicators and health care utilization. A secondary analysis of the 2017 National Survey on Drug Use and Health was conducted (N = 11 884). Ever smokers were less likely to be screened for tobacco use. Current smokers and those who were nicotine dependent were more likely to have been advised to quit use. Ever and current smokers were significantly more likely to report good/fair/poor health status, illness-related school absenteeism in the past 30 days, and were more likely to have had an emergency department visit or an overnight hospital stay. Standardized tobacco control efforts are needed in health care settings to support clinicians to screen all adolescents for tobacco use and advise every smoker irrespective of smoking frequency to quit use.

A Research Agenda for Emergency Medicine-based Adolescent Sexual and Reproductive Health

OBJECTIVE

The objective was to identify key questions for emergency medicine (EM)-based adolescent sexual and reproductive health and to develop an evidence-based research agenda.

METHODS

We recruited national content experts to serve as advisory group members and used a modified Delphi technique to develop consensus around actionable research questions related to EM-based adolescent reproductive and sexual health care. Author subgroups conducted literature reviews and developed the initial list of research questions, which were iteratively refined with advisory members. External stakeholders then independently rated each item for its importance in expanding the evidence base (1 = not important to 5 = very important) via electronic survey.

RESULTS

Our final list of 24 research questions included items that intersected all sexual and reproductive health topics as well as questions specific to human immunodeficiency virus/sexually transmitted infections (HIV/STIs), pregnancy prevention, confidentiality/consent, public health, and barriers and facilitators to care. External stakeholders rated items related to HIV/STI, cost-effectiveness, brief intervention for sexual risk reduction, and implementation and dissemination as most important.

CONCLUSIONS

We identified critical questions to inform EM-based adolescent sexual and reproductive health research. Because evidence-based care has potential to improve health outcomes while reducing costs associated with HIV/STI and unintended pregnancy, funders and researchers should consider increasing attention to these key questions.

Methodology and Demographics of a Brief Adolescent Alcohol Screen Validation Study

OBJECTIVE

The aim of this study was to determine the psychometric properties of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) 2-question alcohol screen within 16 Pediatric Emergency Care Applied Research Network pediatric emergency departments. This article describes the study methodology, sample characteristics, and baseline outcomes of the NIAAA 2-question screen.

METHODS

Participants included 12- to 17-year-olds treated in one of the participating pediatric emergency departments across the United States. After enrollment, a criterion assessment battery including the NIAAA 2-question screen and other measures of alcohol, drug use, and risk behavior was self-administered by participants on a tablet computer. Two subsamples were derived from the sample. The first subsample was readministered the NIAAA 2-question screen 1 week after their initial visit to assess test-retest reliability. The second subsample is being reassessed at 12 and 24 months to examine predictive validity of the NIAAA 2-question screen.

RESULTS

There were 4834 participants enrolled into the study who completed baseline assessments. Participants were equally distributed across sex and age. Forty-six percent of the participants identified as white, and 26% identified as black. Approximately one quarter identified as Hispanic. Using the NIAAA 2-question screen algorithm, approximately 8% were classified as low risk, 12% were classified as moderate risk, and 4% were classified as highest risk. Alcohol use was less likely to be reported by black participants, non-Hispanic participants, and those younger than 16 years.

DISCUSSION

This study successfully recruited a large, demographically diverse sample to establish rates of the NIAAA screen risk categories across age, sex, ethnicity, and race within pediatric emergency departments.

Secondary analysis of an RCT on Emergency Department-Initiated Tobacco Control: Repeatedly assessed point-prevalence abstinence up to 12 months and extension of results through a 10-year follow-up

INTRODUCTION

Emergency departments (EDs) are opportune places for tobacco control interventions. The ‘Tobacco Control in an Urban Emergency Department’ (TED) study, ISRCTN41527831, originally evaluated the effect of motivational interviewing on-site plus up to four booster telephone calls on 12-month abstinence. This study’s aim was to evaluate the effect of the intervention on 7-day point-prevalence abstinence at 10 years follow-up (primary outcome) as well as on repeated point-prevalence abstinence at 1, 3, 6, 12 months and at 10 years (continual smoking abstinence, secondary outcome).

METHODS

At the 10 years follow-up and after informed consent, study participants responded to a mailed questionnaire. The primary outcome was analyzed in observed-only and in all-cases analyses. The secondary outcomes were analyzed using a multiple adjusted GLMM for binary outcomes.

RESULTS

Out of 1012 TED-study participants, 986 (97.4%) were alive and 231 (23.4% of 986) responded to the follow-up at 10 years. For observed-only and all-cases analyses, the effect of the baseline intervention on 7-day point-prevalence abstinence at the 10 years follow-up was statistically non-significant. However, when taking into account all repeated measures, the intervention significantly influenced continual abstinence with odds ratio 1.32 (95% CI: 1.01–1.73; p=0.042). Baseline motivation, perceived self-efficacy to stop smoking, and nicotine dependency were independently associated with long-term continual smoking abstinence (all p<0.05).

CONCLUSIONS

A conventional analysis failed to confirm a significant effect of the ED-initiated tobacco control intervention on the point-prevalence abstinence at 10 years. Results from a more integrative analysis nonetheless indicated an enduring intervention effect on continual abstinence among smokers first encountered in the emergency department setting 10 years earlier.

An example of public health training in emergency medicine

There is growing recognition of the vital roles that Emergency Physicians can play in public health. Accordingly, there is a need for emergency medicine trainees to have opportunities to acquire relevant public health skillsets. This article provides an example of such a possibility. It describes the experience of an emergency medicine trainee in undertaking a 6 month training rotation at a Public Health Unit. The example illustrates the feasibility and benefits of a public health rotation for interested trainees, and offers recommendations for establishing such rotations. There are challenges, including eligibility requirements and funding. However, possible approaches exist at the individual and college levels to facilitate such training opportunities so that emergency medicine trainees can acquire necessary and valuable public health skills.

Screening for Adolescent Alcohol Use in the Emergency Department: What Does It Tell Us About Cannabis, Tobacco, and Other Drug Use?

BACKGROUND

The pediatric emergency department (PED) represents an opportune time for alcohol and drug screening. The National Institute of Alcohol Abuse and Alcoholism (NIAAA) recommends a two-question alcohol screen for adolescents as a predictor of alcohol and drug misuse.

OBJECTIVE

A multi-site PED study was conducted to determine the association between the NIAAA two-question alcohol screen and adolescent cannabis use disorders (CUD), cigarette smoking, and lifetime use of other drugs.

METHODS

Participants included 12-17-year olds (n = 4834) treated in one of 16 participating PEDs. An assessment battery, including the NIAAA two-question screen and other measures of alcohol, tobacco and drug use, was self-administered on a tablet computer.

RESULTS

A diagnosis of CUD, lifetime tobacco use or lifetime drug use was predicted by any self-reported alcohol use in the past year, which indicates a classification of moderate risk for middle school ages and low risk for high school ages on the NIAAA two-question screen. Drinking was most strongly predictive of a CUD, somewhat weaker for lifetime tobacco use, and weakest for lifetime drug use. This same pattern held for high school and middle school students and was stronger for high school students over middle school students for all three categories. This association was also found across gender, ethnicity and race. The association was strongest for CUD for high school students, sensitivity 81.7% (95% CI, 77.0, 86.5) and specificity 70.4% (95% CI, 68.6, 72.1). Conclusions/Importance: A single question about past year alcohol use can provide valuable information about other substance use, particularly marijuana.

Adolescent Tobacco Smoke Exposure, Respiratory Symptoms, and Emergency Department Use

OBJECTIVES

Our objective was to examine the relationship between distinct tobacco smoke exposure (TSE) measures and TSE-related symptoms and emergency department (ED) and/or urgent care (UC) use among nonsmoking adolescents without asthma diagnoses.

METHODS

We performed a secondary analysis of 7389 adolescents who completed the Population Assessment of Tobacco and Health Study wave 2. Logistic regression and Poisson regression models were built.

RESULTS

Adolescents with TSE were at increased risk of reporting: shortness of breath, finding it hard to exercise, wheezing during or after exercise, and dry cough at night. Adolescents who lived with a smoker and had home TSE were at increased odds of reporting wheezing or whistling in the chest, and only adolescents with home TSE were at increased risk of reporting wheezing that disturbed sleep. Adolescents with TSE were less likely to report very good or excellent overall health and physical health but were more likely to report they sometimes, often, or very often missed school because of illness. Participants who lived with a smoker and had TSE ≥1 hour were more likely to have had an ED and/or UC visit. Participants with any TSE were at increased risk of having a higher number of ED and/or UC visits.

CONCLUSIONS

Different TSE measures uniquely increased the risk of TSE-related symptoms, but any TSE increased the risk of having a higher number of ED and/or UC visits. The providers at these high-volume settings should offer interventions to adolescents who are exposed to tobacco smoke and their families to decrease these symptoms and related morbidity.

Results of an RCT in Two Pediatric Emergency Departments to Evaluate the Efficacy of an m-Health Educational App on Car Seat Use

INTRODUCTION

The growing interest in incorporating prevention into emergency health care make it timely to examine the use of computer technology to efficiently deliver effective education in this setting.

STUDY DESIGN

This RCT compared results from an intervention group (n=367) that received child passenger safety information, to an attention-matched control (n=375). A baseline survey and two follow-up surveys at 3 and 6 months were conducted.

SETTING/PARTICIPANTS

Data were collected from June 2014 to September 2016 from a sample of parents with children aged 4-7 years recruited from a pediatric emergency department in an East Coast urban area and one in a Midwest semi-rural area.

INTERVENTION

A theory-based, stage-tailored educational program, Safety in Seconds v2.0^TM, delivered on a mobile app.

MAIN OUTCOME MEASURES

Four car seat behaviors: (1) having the correct restraint for the child's age and weight; (2) having the child ride in the backseat all the time; (3) buckling up the child all the time; and (4) having the child's restraint inspected by a child passenger safety technician.

RESULTS

At 3 months, adjusting for baseline behaviors and attrition, the odds of reporting the correct behavior by the intervention group relative to the control group was 2.07 (p<0.01) for using the correct car seat; 2.37 (p<0.05) times for having the child ride in the back seat; 1.04 (nonsignificant) for riding buckled up all the time; and 1.99 (p<0.01) times for having the car seat inspected. At 6 months, there were statistically significant effects for reporting use of the correct car seat (OR=1.84, p<0.01) and having the car seat inspected (OR=1.73, p<0.01).

CONCLUSIONS

Mobile apps hold promise for reaching large populations with individually tailored child passenger safety education.

Exploring Older Adult ED Fall Patients' Understanding of Their Fall: A Qualitative Study

Objective:

We sought to understand older patients’ perspectives about their fall, fall risk factors, and attitude toward emergency department (ED) fall-prevention interventions.

Methods:

We conducted semistructured interviews between July 2015 and January 2016 of community-dwelling, nondemented patients in the ED, who presented with a fall to an urban, teaching hospital. Interviews were halted once we achieve thematic saturation with the data coded and categorized into themes.

Results:

Of the 63 patients interviewed, patients blamed falls on the environment, accidents, a medical condition, or themselves. Three major themes were generated: (1) patients blamed falls on a multitude of things but never acknowledged a possible multifactorial rationale, (2) patients have variable level of concerns regarding their current fall and future fall risk, and (3) patients demonstrated a range of receptiveness to ED interventions aimed at preventing falls but provided little input as to what those interventions should be.

Conclusions:

Many older patients who fall do not understand their fall risk. However, based on the responses provided, older adults tend to be more receptive to intervention and more concerned about their future fall risk, making the ED an appropriate setting for intervention.

Emergency Department-Initiated Tobacco Control: Update of a Systematic Review and Meta-Analysis of Randomized Controlled Trials

INTRODUCTION

A 2012 systematic review and meta-analysis of randomized controlled trials on emergency department-initiated tobacco control (ETC) showed only short-term efficacy. The aim of this study was to update data through May 2015.

METHODS

After registering the study protocol on the international prospective register of systematic reviews (PROSPERO) in May 2015, we searched 7 databases and the gray literature. Our outcome of interest was the point prevalence of tobacco-use abstinence at 1-month, 3-month, 6-month, or 12-month follow-up. We calculated the relative risk (RR) of tobacco-use abstinence after ETC at each follow-up time separately for each study and then pooled Mantel-Haenszel RRs by follow-up time. These results were pooled with results of the 7 studies included in the previous review. We calculated the effect of ETC on the combined point prevalence of tobacco-use abstinence across all follow-up times by using generalized linear mixed models.

RESULTS

We retrieved 4 additional studies, one published as an abstract, comprising 1,392 participants overall. The 1-month follow-up point prevalence of tobacco-use abstinence after ETC resulted in an RR of 1.49 (95% confidence interval [CI], 1.08-2.05) across 3 studies; 3-month follow-up, an RR of 1.38 (95% CI, 1.12-1.71) across 9 studies; 6-month follow-up, an RR of 1.09 (95% CI, 0.84-1.41) across 6 studies; and 12-month follow-up, an RR of 1.26 (95% CI, 1.00-1.59) across 3 studies. The effect on the combined point prevalence of abstinence was an RR of 1.40 (95% CI, 1.06-1.86) (P = .02).

CONCLUSION

ETC is effective in promoting continual tobacco-use abstinence up to 12 months after intervention. ETC may be a critically important public health strategy for engaging hard-to-reach smokers in tobacco-use cessation.

Randomized controlled trial of emergency department initiated smoking cessation counselling and referral to a community counselling service

OBJECTIVE

Worldwide, tobacco smoke is still the leading cause of preventable morbidity and mortality. Many smokers develop chronic smoking-related conditions that require emergency department (ED) visits. However, best practices for ED smoking cessation counselling are still unclear.

METHODS

A randomized controlled trial was conducted to determine whether an "ask, advise, and refer" approach increases 12-month, 30-day quit rates in the stable adult ED smoking population compared to usual care. Patients in the intervention group were referred to a community counselling service that offers a quitline, a text-based program, and a Web-based program. Longitudinal intention-to-treat analyses were performed.

RESULTS

From November 2011 to March 2013, 1,295 patients were enrolled from one academic tertiary care ED. Six hundred thirty-five were allocated to usual care, and 660 were allocated to intervention. Follow-up data were available for 70% of all patients at 12 months. There was no statistically significant difference in 12-month, 30-day quit rates between the two groups. However, there was a trend towards higher 7-day quit attempts, 7-day quit rates, and 30-day quit rates at 3, 6, and 12 months in the intervention group.

CONCLUSION

In this study, there was a trend towards increased smoking cessation following referral to a community counselling service. There was no statistically significant difference. However, if ED smoking cessation efforts were to provide even a small positive effect, such an intervention may have a significant public health impact given the extensive reach of emergency physicians.

Reliability and Validity of a Two-Question Alcohol Screen in the Pediatric Emergency Department

BACKGROUND AND OBJECTIVE

A multisite study was conducted to determine the psychometric properties of the National Institute of Alcohol Abuse and Alcoholism (NIAAA) 2-question alcohol screen within pediatric emergency departments (PEDs).

METHODS

Participants (N = 4838) included 12- to 17-year-old subjects treated in 1 of the 16 participating PEDs across the United States. A criterion assessment battery (including the NIAAA 2-question alcohol screen and other measures of alcohol, drug use, and risk behaviors) was self-administered on a tablet computer. A subsample (n = 186) was re-administered the NIAAA 2-question screen 1 week later to assess test-retest reliability.

RESULTS

Moderate to good test-retest reliability was demonstrated. A classification of moderate risk or higher on the screen had the best combined sensitivity and specificity for determining a diagnosis of alcohol use disorder (AUD) for all students. Any past year drinking among middle school students increased the odds of a diagnosis of an AUD according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria, whereas the optimal cutoff for high school ages was ≥3 drinking days in the past year. The optimal cutoff for drinking days determining a positive Alcohol Use Disorders Identification Test score among middle school subjects was ≥1 drinking day, whereas the optimal cutoff for high school subjects was ≥2 drinking days.

CONCLUSIONS

The NIAAA 2-question screen is a brief, valid approach for alcohol screening in PEDs. A positive screen suggests that referral for further evaluation is indicated to determine if an adolescent has an AUD.

Choice of smoking cessation counselling via phone, text, or email in emergency department patients

Globally, tobacco smoke is the leading cause of preventable deaths. Smoking cessation counselling services are widely available in Canada. In British Columbia, our government-funded smoking cessation service offers counselling via phone, text, or email. In this study, we sought to determine whether age, gender, or motivation to quit affect a patient's choice of service modality.

We included all adults ≥ 18 years who had used tobacco within 30 days prior to their Emergency Department (ED) visit and who chose to receive phone, text, or email counselling services from November 2011–February 2013 at Vancouver General Hospital as part of a randomized-controlled trial (ClinicalTrials.gov, NCT0145437). A one-way ANOVA was used to compare the mean age of patients in each group. Chi-squared tests of independence were used to determine if gender or motivation to quit were associated with modality selection.

In total, 368 patients were included. The average age was 41.7 years and 67% were female. In our study, 44% chose phone, 17% chose text, and 40% chose email services. The average age for patients preferring text services (mean = 33.6 years) was significantly lower than both the email (mean = 41.3 years) and phone (mean = 45.1 years) groups (p < 0.001). Gender and motivation to quit were not associated with service modality choice.

Over 80% of ED smokers who accepted a referral to counselling services chose the phone or email modality. The lesser chosen text modality was more popular with younger patients. With further research, smoking cessation counselling services can refine their programs to meet the needs of the population they serve.

•

Many smoking cessation quit lines offer counselling by phone, text, or internet.

•

> 80% of smokers in our study who accepted referral chose phone or internet counselling.

•

The lesser chosen text referral modality was more popular with younger patients.

•

Smoking cessation counselling services should work to meet their demographic's needs.

•

Counselling services that text should know they may attract a younger population.

Evaluating a smartphone application to improve child passenger safety and fire safety knowledge and behaviour

BACKGROUND

Although proven measures for reducing injury due to motor vehicle collision and residential fires exist, the number of families properly and consistently using child passenger restraints and smoke alarms remains low. This paper describes the design of the Safety In Seconds (SIS) 2.0 study, which aims to evaluate the impact of a smartphone app on parents' use of child restraints and smoke alarms.

METHODS

SIS is a multisite randomised controlled trial. Participants are parents of children aged 4-7 years who are visiting the Pediatric Emergency Department or Pediatric Trauma Service. Parents are randomised to receive tailored education about child passenger safety or about fire safety via the SIS smartphone app. A baseline and two follow-up surveys at 3 months and 6 months are conducted. Primary outcomes are: (1) having the correct child restraint for the child's age and size; (2) restraining the child in the back seat of the car; (3) buckling the child up for every ride; (4) having the restraint inspected by a child passenger safety technician; (5) having a working smoke alarm on every level of the home; (6) having hard-wired or lithium battery smoke alarms; (7) having and (8) practising a fire escape plan.

DISCUSSION

Finding ways to communicate with parents about child passenger and fire safety continues to be a research priority. This study will contribute to the evidence about how to promote benefits of proper and consistent child restraint and smoke alarm use.

Prevalence of Diagnosed and Undiagnosed Hepatitis C in a Midwestern Urban Emergency Department

BACKGROUND

Targeted hepatitis C virus (HCV) screening is recommended. Implementation of screening in emergency department (ED) settings is challenging and controversial. Understanding HCV epidemiology in EDs could motivate and guide screening efforts. We characterized the prevalence of diagnosed and undiagnosed HCV in a Midwestern, urban ED.

METHODS

This was a cross-sectional seroprevalence study using de-identified blood samples and self-reported health information obtained from consecutively approached ED patients aged 18-64 years. Subjects consented to a "study of diseases of public health importance" and were compensated for participation. The Biochain ELISA kit for Human Hepatitis C Virus was used for antibody assay. Viral RNA was isolated using the Qiagen QIAamp UltraSens Virus kit, followed by real-time reverse transcription polymerase chain reaction using a Bio-Rad CFX96 SYBR Green UltraFast program with melt-curve analysis.

RESULTS

HCV antibody was detected in 128 of 924 (14%; 95% confidence interval [CI], 12%-16%) samples. Of these, 44 (34%) self-reported a history of HCV or hepatitis of unknown type and 103 (81%; 95% CI, 73%-87%) were RNA positive. Two additional patients were antibody negative but RNA positive. Fully implemented birth cohort screening for HCV antibody would have missed 36 of 128 (28%) of cases with detectable antibody and 26 of 105 (25%) of those with replicative HCV infection.

CONCLUSIONS

HCV infection is highly prevalent in EDs. Emergency departments are likely to be uniquely important for HCV screening, and logistical challenges to ED screening should be overcome. Birth cohort screening would have missed many patients, suggesting the need for complementary screening strategies applied to an expanded age range.

Public Health Information Delivery in the Emergency Department: Analysis of a Kiosk-Based Program

BACKGROUND

Because more than one-third of the U.S. population visits an emergency department (ED) any given year, public health interventions in the ED can have major population-level impacts.

OBJECTIVES

We determined ED patients' interest in receiving information via kiosk on common, chronic conditions for which education and preventive screening could offer public health benefit and to assess what topical information patients are interested in receiving.

METHODS

This is a secondary analysis of survey data from an ED pilot program December 2011 to April 2012. Main outcome measures were patients' interests in receiving information on health topics via kiosk module.

RESULTS

More than half of the 4351 patients indicated interest in receiving information on at least one health topic, including high blood pressure (30%), depression (21%), diabetes (18%), sexually transmitted diseases (11%), drug abuse (6%), and physical abuse (3%). African-American patients were more likely to be interested in receiving information on high blood pressure (odds ratio [OR] 2.7, 95% confidence interval [95% CI] 2.2-3.2]), depression (OR 1.3, 95% CI 1.1-1.6), diabetes/sugar (OR 2.2, 95% CI 1.8-2.8), drug abuse (OR 1.4, 95% CI 1.0-1.9), and sexually transmitted diseases (OR 2.6, 95% CI 1.9-3.7). Participants >55 years of age were more likely to desire information on high blood pressure and diabetes (age 55-64 years: OR 4.0, 95% CI 3.1-5.1; age >64 years: OR 4.4, 95% CI 3.2-6.2). Patients who were interested in receiving public health information were more likely to be older, African American, and male (p < 0.05).

CONCLUSIONS

Interest in obtaining kiosk-delivered education on hypertension predominated. Kiosks are versatile tools that could be used in ED settings to provide health education services.

Predicting future emergency department visits and hospitalizations for asthma using the Pediatric Asthma Control and Communication Instrument - Emergency Department version (PACCI-ED)

OBJECTIVE

Emergency departments (EDs) are potential settings for interventions to improve asthma outcomes. Screening tools can identify children at risk of future morbidity. Our objective was to determine the predictive validity of the Pediatric Asthma Control and Communication Instrument - Emergency Department version (PACCI-ED) for future asthma-related ED visits and hospitalizations.

METHODS

This was a retrospective cohort study of 108 children 1-17 years old who visited an ED for asthma and completed the PACCI-ED. The PACCI-ED queries parents about prior 12-month ED visits, hospitalizations, steroid use, perceived asthma morbidity and burden, and asthma control (over prior 1-2 weeks). The primary outcome was subsequent ED visits and hospitalizations within 1 year of enrollment. Poisson regression was used to model PACCI-ED questions for future ED visits controlling for age and socioeconomic status.

RESULTS

Reported ED visits predicted future ED visits (adjusted incidence rate ratio (aIRR) 3.1, 95% confidence interval (CI): 1.3-7.2) but not future hospitalizations. Reported hospitalizations predicted future ED visits (aIRR 3.3; 95% CI 1.7-6.3) and hospitalizations (aIRR 6.4; 95% CI 2.3-17.6). The remaining PACCI-ED questions did not predict future ED visits or hospitalizations.

CONCLUSIONS

The PACCI-ED risk domain was the only domain that predicted future asthma ED visits and hospitalizations. Questions about previous ED visits and hospitalizations are the most effective questions when screening children with asthma in EDs for the risk of future health-care use.

Screening of mental health and substance users in frequent users of a general Swiss emergency department

Background

The objectives of this study were to determine the proportions of psychiatric and substance use disorders suffered by emergency departments’ (EDs’) frequent users compared to the mainstream ED population, to evaluate how effectively these disorders were diagnosed in both groups of patients by ED physicians, and to determine if these disorders were predictive of a frequent use of ED services.

Methods

This study is a cross-sectional study with concurrent and retrospective data collection. Between November 2009 and June 2010, patients’ mental health and substance use disorders were identified prospectively in face-to-face research interviews using a screening questionnaire (i.e. researcher screening). These data were compared to the data obtained from a retrospective medical chart review performed in August 2011, searching for mental health and substance use disorders diagnosed by ED physicians and recorded in the patients’ ED medical files (i.e. ED physician diagnosis). The sample consisted of 399 eligible adult patients (≥18 years old) admitted to the urban, general ED of a University Hospital. Among them, 389 patients completed the researcher screening. Two hundred and twenty frequent users defined by >4 ED visits in the previous twelve months were included and compared to 169 patients with ≤4 ED visits in the same period (control group).

Results

Researcher screening showed that ED frequent users were more likely than members of the control group to have an anxiety, depressive disorder, post-traumatic stress disorder (PTSD), or suffer from alcohol, illicit drug abuse/addiction. Reviewing the ED physician diagnosis, we found that the proportions of mental health and substance use disorders diagnosed by ED physicians were low both among ED frequent users and in the control group. Using multiple logistic regression analyses to predict frequent ED use, we found that ED patients who screened positive for psychiatric disorders only and those who screened positive for both psychiatric and substance use disorders were more likely to be ED frequent users compared to ED patients with no disorder.

Conclusions

This study found high proportions of screened mental health and/or substance use disorders in ED frequent users, but it showed low rates of detection of such disorders in day-to-day ED activities which can be a cause for concern. Active screening for these disorders in this population, followed by an intervention and/or a referral for treatment by a case-management team may constitute a relevant intervention for integration into a general ED setting.

Adolescents Who Visit the Emergency Department Are More Likely to Make Unhealthy Dietary Choices: An Opportunity for Behavioral Intervention

To identify health behaviors that may be amenable to brief screening and intervention among children in the emergency department (ED), we described the prevalence of health behaviors known to contribute to childhood obesity among middle school students who used the ED recently. Participants included 1590 5th, 7th, and 8th grade students who completed health surveys in 2011. Multivariate logistic regression was used to examine the association between health behaviors and ED use. Children who used the ED reported more unhealthy dietary behaviors, including greater consumption of energy-dense foods such as fried chicken, french fries, and ice cream (OR 1.20, 95% CI 1.06-1.37), fast food (OR 1.07, 95% CI 1.00-1.14) and sugar-sweetened beverages (OR 1.24, 95% CI 1.14-1.35). There was no association with fruit and vegetable consumption, physical activity, or screen time. Unhealthy dietary behaviors are associated with ED use in a low-resource urban population of middle school students.

Correlation between Subclinical Heart Disease and Cardiovascular Risk Profiles in an Urban Emergency Department Population with Elevated Blood Pressures: A Pilot Study

BACKGROUND

Uncontrolled hypertension is a primary risk factor for development of cardiovascular complications.

OBJECTIVE

Determine the point prevalence of left ventricular hypertrophy (LVH) and diastolic dysfunction in an urban emergency department (ED) population with elevated blood pressures (BP) and examine correlations between subclinical disease and patient cardiovascular risk profiles.

METHODS

A convenience sample of patients with EBP (>140/90 on two measurements) had limited bedside echocardiograms (LBE). Subclinical hypertensive heart disease was classified as the presence of: LVH, abnormal ejection fraction (EF), or diastolic dysfunction.

RESULTS

Thirty-nine patients with EBP were enrolled. The mean age was 46 years (SD = 10.9), 59% were women, 21% were smokers, and 92% had a history of hypertension. The average body mass index was 30.7 (SD = 8.7). Patients were 67% African American, 23% Latino, 5% Caucasian, 3% Asian, and 3% Native American. Subclinical disease was found in 39%: 31% had LVH, 15% had diastolic dysfunction, and 8% had abnormal EF. On bivariate analysis, elevated BP (p = 0.039) and blood urea nitrogen (p = 0.016) were correlated with subclinical heart disease. After adjusting for other covariates, receiving oral/intravenous antihypertensive medications in the ED (p = 0.005) was associated with subclinical heart disease.

CONCLUSIONS

We found a point prevalence of subclinical heart disease of 39% in this urban ED population, using LBE. Real-time identification of subclinical heart disease at early stages in the ED in conjunction with abnormal renal function can help emergency physicians identify those patients in need of more aggressive therapy and urgent follow-up.

Survey of an Australian general emergency department: estimated prevalence of mental health disorders

Compared to the general population, people with mental health disorders have an increased risk of morbidity and mortality, and are associated with higher health-care costs and lost societal productivity. Evidence indicates that more people are presenting to emergency departments with mental health disorders and that this group represents a disproportionately large number of emergency department attendees. The study results indicate that around a third of people who attended the emergency department may have had a mental health disorder, which is more than that found in the general adult Australian population. The results also suggest that the majority of emergency department attendees that have a mental health disorder are not identified at this opportunistic point of contact. The emergency department is an ideal point of contact to screen people for mental health problems. If problems are identified early, and treatment is started early, then it is likely that more people would be helped before their mental health problem became severe. However, increased identification of mental health problems may have implications for mental health services in terms of workload and delivery. The aim of this study was to estimate the prevalence of mental health disorders in an Australian general emergency department. A cross-sectional survey was used to screen a sample of 708 patients, using the Kessler Psychological Distress Scale (K10). The mean age of participants was 50.2 years, and their mean K10 score was 19.96 (SD 7.83), with 24% categorized as having high or very high psychological distress. Seventeen per cent self-reported having a mental health issue. Post-probability calculations based on observed K10 scores estimated that 37% of participants had an actual mental health disorder. The results suggest the prevalence of mental health disorder is significantly higher in emergency department attendees than Australian population norms, supporting the contention that a substantial proportion of ED attendees has a mental health disorder that, in the majority of cases, is not investigated at this point of contact. There is potential to screen all emergency department attendees for the presence of mental health disorder; early identification of mental illness would enable early referral for treatment. However, if all patients are screened, then it is likely that more mental health conditions will be picked up. The implications for mental health nursing are that this may increase workload.

Barriers to and enablers of contraceptive use among adolescent females and their interest in an emergency department based intervention

OBJECTIVE

Over 15 million adolescents, many at high risk for pregnancy, use emergency departments (EDs) in the United States annually, but little is known regarding reasons for failure to use contraceptives in this population. The purpose of this study was to identify the barriers to and enablers of contraceptive use among adolescent females using the ED and determine their interest in an ED-based pregnancy prevention intervention.

STUDY DESIGN

We conducted semistructured, open-ended interviews with females in an urban ED. Eligible females were 14-19 years old, sexually active, presenting for reproductive health complaints and at risk for pregnancy, defined as nonuse of effective (per the World Health Organization) contraception. Interviews were recorded, transcribed and coded based on thematic analysis. Enrollment continued until no new themes emerged. A modified Health Belief Model guided the organization of the data.

RESULTS

Participants (n=14) were predominantly Hispanic (93%), insured (93%) and in a sexual relationship (86%). The primary barrier to contraceptive use was perceived health risk, including effects on menstruation, weight and future fertility. Other barriers consisted of mistrust in contraceptives, ambivalent pregnancy intentions, uncertainty about the future, partner's desire for pregnancy and limited access to contraceptives. Enablers of past contraceptive use included the presence of a school-based health clinic and clear plans for the future. All participants were receptive to ED-based pregnancy prevention interventions.

CONCLUSIONS

The identified barriers and enablers influencing hormonal contraceptive use can be used to inform the design of future ED-based adolescent pregnancy prevention interventions.

IMPLICATIONS

Adolescents who visit the emergency department (ED) identify contraceptive side effects, mistrust in contraceptives, limited access, pregnancy ambivalence and partner pregnancy desires as barriers to hormonal contraception use. They expressed interest in an ED-based intervention to prevent adolescent pregnancy; such an intervention could target these themes to maximize effectiveness.

Impact of gender on patient preferences for technology-based behavioral interventions

Introduction:

Technology-based interventions offer an opportunity to address high-risk behaviors in the emergency department (ED). Prior studies suggest behavioral health strategies are more effective when gender differences are considered. However, the role of gender in ED patient preferences for technology-based interventions has not been examined. The objective was to assess whether patient preferences for technology-based interventions varies by gender.

Methods:

This was a secondary analysis of data from a systematic survey of adult (≥18 years of age), English-speaking patients in a large urban academic ED. Subjects were randomly selected during a purposive sample of shifts. The iPad survey included questions on access to technology, preferences for receiving health information, and demographics. We defined “technology-based” as web, text message, e-mail, social networking, or DVD; “non-technology-based” was defined as in-person, written materials, or landline. We calculated descriptive statistics and used univariate tests to compare men and women. Gender-stratified multivariable logistic regression models were used to examine associations between other demographic factors (age, race, ethnicity, income) and technology-based preferences for information on specific risky behaviors.

Results:

Of 417 participants, 45.1% were male. There were no significant demographic differences between men and women. Women were more likely to use computers (90.8% versus 81.9%; p=0.03), Internet (66.8% versus 59.0%; p=0.03), and social networks (53.3% versus 42.6%; p=0.01). 89% of men and 90% of women preferred technology-based formats for at least type of health information; interest in technology-based for individual health topics did not vary by gender. Concern about confidentiality was the most common barrier to technology-based use for both genders. Multivariate analysis showed that for smoking, depression, drug/alcohol use, and injury prevention, gender modified the relationship between other demographic factors and preference for technology-based health information; e.g., older age decreases interest in technology-based information for smoking cessation in women but not in men (aOR 0.96, 95% CI 0.93-0.99 versus aOR 1.00, 95% CI 0.97-1.03).

Conclusion:

Our findings suggest ED patients' gender may affect technology preferences. Receptivity to technology-based interventions may be a complex interaction between gender and other demographic factors. Considering gender may help target ED patient populations most likely to be receptive to technology-based interventions.

Characteristics of youth seeking emergency care for assault injuries

OBJECTIVE

To characterize youth seeking care for assault injuries, the context of violence, and previous emergency department (ED) service utilization to inform ED-based injury prevention.

METHODS

A consecutive sample of youth (14-24) presenting to an urban ED with an assault injury completed a survey of partner violence, gun/knife victimization, gang membership, and context of the fight.

RESULTS

A total of 925 youth entered the ED with an assault injury; 718 completed the survey (15.4% refused); 730 comparison youth were sampled. The fights leading to the ED visit occurred at home (37.6%) or on streets (30.4%), and were commonly with a known person (68.3%). Fights were caused by issues of territory (23.3%) and retaliation (8.9%); 20.8% of youth reported substance use before the fight. The assault-injured group reported more peer/partner violence and more gun experiences. Assault-injured youth reported higher past ED utilization for assault (odds ratio [OR]: 2.16) or mental health reasons (OR: 7.98). Regression analysis found the assault-injured youth had more frequent weapon use (OR: 1.25) and substance misuse (OR: 1.41).

CONCLUSIONS

Assault-injured youth seeking ED care report higher levels of previous violence, weapon experience, and substance use compared with a comparison group seeking care for other complaints. Almost 10% of assault-injured youth had another fight-related ED visit in the previous year, and ~5% had an ED visit for mental health. Most fights were with people known to them and for well-defined reasons, and were therefore likely preventable. The ED is a critical time to interact with youth to prevent future morbidity.

Experiences of pediatric emergency physicians in providing alcohol-related care to adolescents in the emergency department

OBJECTIVE

The emergency department (ED) is a key clinical care setting for identifying and managing patients with alcohol-related presentations. We explored the experiences of emergency physicians in providing alcohol-related care to adolescents.

METHODS

Purposeful sampling was used to identify pediatric emergency physicians with at least 1 year of experience (n = 12) from pediatric EDs across Canada. Data were collected via telephone using a semistructured interview guide. Hermeneutic phenomenology was used to identify common and unique experiences among respondents, using Moustakas' immersion/crystallization procedures.

RESULTS

Physicians expressed frustration with patient behaviors accompanying intoxication and described providing care as a struggle; developing an effective therapeutic alliance was challenging. Physicians believed intoxicated adolescent patients required more clinical time and resources than they could offer. Although physicians described the ED as unsuitable for ensuring continuity of care and addressing the broader social issues that accompany alcohol use, they did view the ED as a place to medically stabilize the patient and initiate a discussion on alcohol use and its harmful effects.

CONCLUSIONS

Pediatric ED physicians struggled during the caring experience and were skeptical that broader, more chronic social issues that are often associated with adolescent alcohol misuse can be effectively managed in a clinical setting where they feel primarily responsible for providing medical stabilization. Physicians did believe the ED was an appropriate place to ensure medical stability of a patient and then initiate a conversation regarding alcohol use and its harmful effects.

Randomized comparison of universal and targeted HIV screening in the emergency department

OBJECTIVE

Universal HIV screening is recommended but challenging to implement. Selectively targeting those at risk is thought to miss cases, but previous studies are limited by narrow risk criteria, incomplete implementation, and absence of direct comparisons. We hypothesized that targeted HIV screening, when fully implemented and using maximally broad risk criteria, could detect nearly as many cases as universal screening with many fewer tests.

METHODS

This single-center cluster-randomized trial compared universal and targeted patient selection for HIV screening in a lower prevalence urban emergency department. Patients were excluded for age (<18 and >64 years), known HIV infection, or previous approach for HIV testing that day. Targeted screening was offered for any risk indicator identified from charts, staff referral, or self-disclosure. Universal screening was offered regardless of risk. Baseline seroprevalence was estimated from consecutive deidentified blood samples.

RESULTS

There were 9572 eligible visits during which the patient was approached. For universal screening, 40.8% (1915/4692) consented with 6 being newly diagnosed [0.31%, 95% confidence interval (CI): 0.13% to 0.65%]. For targeted screening, 37% (1813/4880) had no testing indication. Of the 3067 remaining, 47.4% (1454) consented with 3 being newly diagnosed (0.22%, 95% CI: 0.06% to 0.55%). Estimated seroprevalence was 0.36% (95% CI: 0.16% to 0.70%). Targeted screening had a higher proportion consenting (47.4% vs. 40.8%, P < 0.002), but a lower proportion of ED encounters with testing (29.7% vs. 40.7%, P < 0.002).

CONCLUSIONS

Targeted screening, even when fully implemented with maximally permissive selection, offered no important increase in positivity rate or decrease in tests performed. Universal screening diagnosed more cases, because more were tested, despite a modestly lower consent rate.

Developing emergency department-based education about emergency contraception: adolescent preferences

OBJECTIVES

The objective was to identify adolescent preferences for emergency department (ED)-based education about emergency contraception.

METHODS

This was a cross-sectional computerized survey, using adaptive conjoint analysis (ACA). Patients were eligible if they were females ages 14 through 19 years old and were seeking care in one of two urban EDs. Patients were excluded if they were too ill to participate in the survey or if they were non-English speaking. Participants completed a computerized survey that used ACA, a technique that can be used to assess patients' relative preferences for services. ACA uses the individual's answers to update and refine questions through trade-off comparisons, so that each respondent answers a customized set of questions. The survey assessed preferences for the following attributes of emergency contraception education: who should deliver the education, if anyone (e.g., nurse, doctor); how the education should be delivered (e.g., by a person or via video); how often the education should be offered if patients were to frequent the ED (e.g., every time or only when asking for it); length (e.g., 5 minutes, 10 minutes); and chief complaint that would trigger the education (e.g., headache or stomach pain).

RESULTS

A total of 223 patients were enrolled (37.2% at Hospital 1 and 62.8% at Hospital 2). The mean (±SD) age of the participants was 16.1 (±1.3) years. Just over half (55%) reported a history of sexual activity; 8% reported a history of pregnancy. Overall, the participants preferred education that was delivered by a person, specifically a doctor or nurse. They preferred a slightly longer education session and preferred education directed at patients seeking care in the ED for complaints potentially related to sexual activity.

CONCLUSIONS

Adolescents have specific preferences for how education about emergency contraception would best serve their needs. This information can inform clinicians as they work to improve adolescents' knowledge about pregnancy prevention and emergency contraception in particular.

Attitudes towards homeless people among emergency department teachers and learners: a cross-sectional study of medical students and emergency physicians

BACKGROUND

Medical students' attitudes and beliefs about homeless people may be shaped by the attitudes of their teachers and one of the most common sites for learning about homeless patients is the emergency department. The objective of this study was to determine if medical students in the preclinical and clinical years and emergency medicine faculty and residents have different attitudes and beliefs about homeless people.

METHODS

The Health Professional Attitudes Toward the Homeless Inventory (HPATHI), was administered to all medical students, and emergency medicine physicians and residents at a large academic health sciences center in Canada. The HPATHI examines attitudes, interest and confidence on a 5-point Likert scale. Differences among groups were examined using the Kruskal Wallis test and Pearson's chi-square test.

RESULTS

The HPATHI was completed by 371 individuals, for an overall response rate of 55%. Analysis of dichotomized median and percentage results revealed 5/18 statements were significant by both methods. On the attitudes subscales physicians and residents as a group were more negative for 2/9 statements and on the confidence subscale more positive for 1/4 statements. The interest subscale achieved overall statistical significance with decreased positive responses among physicians and residents compared to medical students in 2/5 statements.

CONCLUSION

This study revealed divergences in attitudes, interests and beliefs among medical students and emergency medicine physicians and residents. We offer strategies for training interventions and systemic support of emergency faculty. Emergency medicine physicians can examine their role in the development of medical students through both formal and informal teaching in the emergency department.

Emergency department-based brief intervention to reduce risky driving and hazardous/harmful drinking in young adults: a randomized controlled trial

BACKGROUND

Risky driving and hazardous drinking are associated with significant human and economic costs. Brief interventions for more than one risky behavior have the potential to reduce health-compromising behaviors in populations with multiple risk-taking behaviors such as young adults. Emergency department (ED) visits provide a window of opportunity for interventions meant to reduce both risky driving and hazardous drinking.

METHODS

We determined the efficacy of a Screening, Brief Intervention, and Referral to Treatment (SBIRT) protocol addressing risky driving and hazardous drinking. We used a randomized controlled trial design with follow-ups through 12 months. ED patients aged 18 to 44 who screened positive for both behaviors (n = 476) were randomized to brief intervention (BIG), contact control (CCG), or no-contact control (NCG) groups. The BIG (n = 150) received a 20-minute assessment and two 20-minute interventions. The CCG (n = 162) received a 20-minute assessment at baseline and no intervention. The NCG (n = 164) were asked for contact information at baseline and had no assessment or intervention. Outcomes at 3, 6, 9, and 12 months were self-reported driving behaviors and alcohol consumption.

RESULTS

Outcomes were significantly lower in BIG compared with CCG through 6 or 9 months, but not at 12 months: Safety belt use at 3 months (adjusted odds ratio [AOR], 0.22; 95% confidence interval [CI], 0.08 to 0.65); 6 months (AOR, 0.13; 95% CI, 0.04 to 0.42); and 9 months (AOR, 0.18; 95% CI, 0.06 to 0.56); binge drinking at 3 months (adjusted rate ratio [ARR] 0.84; 95% CI, 0.74 to 0.97) and 6 months (ARR, 0.81; 95% CI, 0.67 to 0.97); and ≥5 standard drinks/d at 3 months (AOR, 0.43; 95% CI, 0.20 to 0.91) and 6 months (AOR, 0.41; 95% CI, 0.17 to 0.98). No substantial differences were observed between BIG and NCG at 12 months.

CONCLUSIONS

Our findings indicate that SBIRT reduced risky driving and hazardous drinking in young adults, but its effects did not persist after 9 months. Future research should explore methods for extending the intervention effect.
