RESUMO
STUDY OBJECTIVE: Identification of HIV remains a critical health priority for which emergency departments (EDs) are a central focus. The comparative cost-effectiveness of various HIV screening strategies in EDs remains largely unknown. The goal of this study was to compare programmatic costs and cost-effectiveness of nontargeted and 2 forms of targeted opt-out HIV screening in EDs using results from a multicenter, pragmatic randomized clinical trial. METHODS: This economic evaluation was nested in the HIV Testing Using Enhanced Screening Techniques in Emergency Departments (TESTED) trial, a multicenter pragmatic clinical trial of different ED-based HIV screening strategies conducted from April 2014 through January 2016. Patients aged 16 years or older, with normal mental status and not critically ill, or not known to be living with HIV were randomized to 1 of 3 HIV opt-out screening approaches, including nontargeted, enhanced targeted, or traditional targeted, across 4 urban EDs in the United States. Each screening method was fully integrated into routine emergency care. Direct programmatic costs were determined using actual trial results, and time-motion assessment was used to estimate personnel activity costs. The primary outcome was newly diagnosed HIV. Total annualized ED programmatic costs by screening approach were calculated using dollars adjusted to 2023 as were costs per patient newly diagnosed with HIV. One-way and multiway sensitivity analyses were performed. RESULTS: The trial randomized 76,561 patient visits, resulting in 14,405 completed HIV tests, and 24 (0.2%) new diagnoses. Total annualized new diagnoses were 12.9, and total annualized costs for nontargeted, enhanced targeted, and traditional targeted screening were $111,861, $88,629, and $70,599, respectively. Within screening methods, costs per new HIV diagnoses were $20,809, $23,554, and $18,762, respectively. Enhanced targeted screening incurred higher costs but with similar annualized new cases detected compared with traditional targeted screening. Nontargeted screening yielded an incremental cost-effectiveness ratio of $25,586 when compared with traditional targeted screening. Results were most sensitive to HIV prevalence and costs of HIV tests. CONCLUSION: Nontargeted HIV screening was more costly than targeted screening largely due to an increased number of HIV tests performed. Each HIV screening strategy had similar within-strategy costs per new HIV diagnosis with traditional targeted screening yielding the lowest cost per new diagnosis. For settings with budget constraints or very low HIV prevalences, the traditional targeted approach may be preferred; however, given only a slightly higher cost per new HIV diagnosis, ED settings looking to detect the most new cases may prefer nontargeted screening.

BACKGROUND: Integration of a sensitive point-of-care (POC) HIV viral load (VL) test into screening algorithms may help detect acute HIV infection earlier, identify people with HIV (PWH) who are not virally suppressed, and facilitate earlier referral to antiretroviral therapy (ART), or evaluation for pre-exposure prophylaxis (PrEP). This report describes a randomized clinical trial sponsored by the Centers for Disease Control and Prevention (CDC): "Ending the HIV Epidemic Through Point-of-Care Technologies" (EHPOC). The study's primary aim is to evaluate the use of a POC HIV VL test as part of a testing approach and assess the impact on time to linkage to ART or PrEP. The study will recruit people in Baltimore, Maryland, including patients attending a hospital emergency department, patients attending an infectious disease clinic, and people recruited via community outreach. The secondary aim is to evaluate the performance characteristics of two rapid HIV antibody tests approved by the United States Food and Drug Administration (FDA). METHODS: The study will recruit people 18 years or older who have risk factors for HIV acquisition and are not on PrEP, or PWH who are not taking ART. Participants will be randomly assigned to either the control arm or the intervention arm. Participants randomized to the control arm will only receive the standard-of-care (SOC) HIV screening tests. Intervention arm participants will receive a POC HIV VL test in addition to the SOC HIV diagnostic screening tests. Follow up will consist of an interim phone survey conducted at week-4 and an in-person week-12 visit. Demographic and behavioral information, and oral fluid and blood specimens will be collected at enrollment and at week-12. Survey data will be captured in a Research Electronic Data Capture (REDCap) database. Participants in both arms will be referred for either ART or PrEP based on their HIV test results. DISCUSSION: The EHPOC trial will explore a novel HIV diagnostic technology that can be performed at the POC and provide viral assessment. The study may help inform HIV testing algorithms and contribute to the evidence to support same day ART and PrEP recommendations. TRIAL REGISTRATION: NIH ClinicalTrials.gov NCT04793750. Date: 11 March 2021.

BACKGROUND: Point of care diagnostic tests (POCTs) for sexually transmitted infections (STIs) have the potential to improve STI care worldwide. However, barriers to adoption, cost considerations and practitioner priorities may not be uniform globally and over time. We conducted two surveys, 7 years apart, among members of the International Union Against Sexually Transmitted Infections (IUSTI), and compare results here. METHODS: Surveys were given to members attending two IUSTI conferences in 2012 (Australia) and 2019 (Estonia). Descriptive analyses were performed and chi-square or Fisher's exact tests conducted. RESULTS: Amongst N = 190 participants in 2012 and N = 166 in 2019, 61% in 2012 and 77% in 2019 were from high-income countries (HICs). In 2012, 84% of respondents from low- and middle-income countries (LMICs) and 70% from HICs thought cost of test was more important than amount of reimbursement. Trends were similar in 2019. In 2012, unreliability was considered the most important barrier to POCT use by all groups, followed by being laboratory-driven and complexity. In 2019, time frame was considered most important, followed by unreliability and being laboratory-driven. In 2012, the top priority for POCT development among LMIC respondents was early HIV seroconversion (31%), versus chlamydia (57%) for HICs. In 2019, chlamydia remained top priority for HICs (40%), followed by early HIV seroconversion (19%) and gonorrhea (17%); top priorities for LMICs were chlamydia (26%), HPV (24%), and early HIV seroconversion (21%). CONCLUSIONS: Practitioner priorities for STI POCTs may be shifting. Cost may be critical to adoption in all settings. Larger studies are needed to verify findings.

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.

BACKGROUND: Emergency Departments (EDs) can serve as surveillance sites for infectious diseases. Our purpose was to determine the burden of SARS-CoV-2 infection and prevalence of vaccination against COVID-19 among patients attending an urban ED in Baltimore City. METHODS: Using 1914 samples of known exposure status, we developed an algorithm to differentiate previously infected, vaccinated, and unexposed individuals using a combination of antibody assays. We applied this testing algorithm to 4360 samples ED patients obtained in the springs of 2020 and 2021. Using multinomial logistic regression, we determined factors associated with infection and vaccination. RESULTS: For the algorithm, sensitivity and specificity for identifying vaccinated individuals was 100% and 99%, respectively, and 84% and 100% for naturally infected individuals. Among the ED subjects, seroprevalence to SARS-CoV-2 increased from 2% to 24% between April 2020 and March 2021. Vaccination prevalence rose to 11% by mid-March 2021. Marked differences in burden of disease and vaccination coverage were seen by sex, race, and ethnicity. Hispanic patients, though 7% of the study population, had the highest relative burden of disease (17% of total infections) but similar vaccination rates. Women and White individuals were more likely to be vaccinated than men or Black individuals (adjusted odds ratios [aOR] 1.35 [95% CI: 1.02, 1.80] and aOR 2.26 [95% CI: 1.67, 3.07], respectively). CONCLUSIONS: Individuals previously infected with SARS-CoV-2 can be differentiated from vaccinated individuals using a serologic testing algorithm. SARS-CoV-2 exposure and vaccination uptake frequencies reflect gender, race and ethnic health disparities in this urban context. SUMMARY: Using an antibody testing algorithm, we distinguished between immune responses from SARS-CoV-2-infected and vaccinated individuals. When applied to blood samples from an emergency department in Baltimore, disparities in disease burden and vaccine uptake by sex, race, and ethnicity were identified.
RESUMO
Background: Given the lack of new antimicrobials to treat Neisseria gonorrhoeae (NG) infections, reusing previously recommended antimicrobials has been proposed as a strategy to control the spread of multi-drug-resistant NG. We assessed ciprofloxacin susceptibility in a large sample set of NG isolates and identified correlates associated with ciprofloxacin-resistant NG infections. Methods: NG isolates collected in Baltimore, Maryland between 2014 and 2016 were evaluated by Gyrase A (gyrA) PCR and E-test for susceptibility to ciprofloxacin. Clinical characteristics and demographics were evaluated by multivariate regression analysis to identify correlates of ciprofloxacin-resistant NG infections. Results: 510 NG isolates from predominately African American (96.5%), heterosexual (85.7%), and HIV-negative (92.5%) male subjects were included in the study. The overall percentage of isolates with mutant gyrA sequences, indicative of ciprofloxacin resistance, was 32.4%, and significantly increased from 24.7% in 2014 to 45.2% in 2016 (p < 0.001). Participants older than 35 years of age were 2.35 times more likely to have a gyrA mutant NG infection than younger participants (p < 0.001). Race, sexual orientation, symptomology, or co-infection the HIV or syphilis were not associated with a particular NG gyrA genotype. Conclusions: Resistance to ciprofloxacin in Baltimore is lower than other regions and indicates that in this environment, use of ciprofloxacin may be appropriate for targeted treatment provided utilization of enhanced surveillance tools. The targeted use of ciprofloxacin may be more beneficial for individuals under 35 years of age. Point-of-care tests for NG diagnosis and susceptibility testing are urgently needed to identify individuals who can be treated with this targeted approach.
RESUMO
Point-of-care tests (POCTs) offer the opportunity for increased diagnostic capacity in resource-limited settings, where there is lack of electricity, technical capacity, reagents, and infrastructure. Understanding how POCTs are currently used and determining what health care workers (HCWs) need is key to development of appropriate tests. In 2016, we undertook an email survey of 7584 HCWs who had received training at the Infectious Diseases Institute, Uganda, in a wide variety of courses. HCWs were contacted up to three times and asked to complete the survey using Qualtrics software. Of 555 participants answering the survey (7.3% response rate), 62% completed. Ninety-one percent were from Uganda and 50.3% were male. The most commonly-used POCTs were pregnancy tests (74%), urine dipstick (71%), syphilis rapid test (66%), and Gram stain (41%). The majority (74%) practiced syndromic diagnosis for sexually transmitted infections/HIV. Lack of availability of POCTs, increased patient wait time, and lack of training were the leading barriers for POCT use. Increasing POCT availability and training could improve uptake of POCTs for sexually transmitted infections in Africa and decrease syndromic management. This could reduce overtreatment and slow the emergence of antibiotic resistance. This is the first published email survey of HCWs in Uganda; mechanisms to increase the response rate should be evaluated.

OBJECTIVE: A 2010 survey identified disparities in salaries by gender and underrepresented minorities (URM). With an increase in the emergency medicine (EM) workforce since, we aimed to 1) describe the current status of academic EM workforce by gender, race, and rank and 2) evaluate if disparities still exist in salary or rank by gender. METHODS: Information on demographics, rank, clinical commitment, and base and total annual salary for full-time faculty members in U.S. academic emergency departments were collected in 2015 via the Academy of Administrators in Academic Emergency Medicine (AAAEM) Salary Survey. Multiple linear regression was used to compare salary by gender while controlling for confounders. RESULTS: Response rate was 47% (47/101), yielding data on 1,371 full-time faculty: 33% women, 78% white, 4% black, 5% Asian, 3% Asian Indian, 4% other, and 7% unknown race. Comparing white race to nonwhite, 62% versus 69% were instructor/assistant, 23% versus 20% were associate, and 15% versus 10% were full professors. Comparing women to men, 74% versus 59% were instructor/assistant, 19% versus 24% were associate, and 7% versus 17% were full professors. Of 113 chair/vice-chair positions, only 15% were women, and 18% were nonwhite. Women were more often fellowship trained (37% vs. 31%), less often core faculty (59% vs. 64%), with fewer administrative roles (47% vs. 57%; all p < 0.05) but worked similar clinical hours (mean ± SD = 1,069 ± 371 hours vs. 1,051 ± 393 hours). Mean overall salary was $278,631 (SD ± $68,003). The mean (±SD) salary of women was $19,418 (±$3,736) less than men (p < 0.001), even after adjusting for race, region, rank, years of experience, clinical hours, core faculty status, administrative roles, board certification, and fellowship training. CONCLUSIONS: In 2015, disparities in salary and rank persist among full-time U.S. academic EM faculty. There were gender and URM disparities in rank and leadership positions. Women earned less than men regardless of rank, clinical hours, or training. Future efforts should focus on evaluating salary data by race and developing systemwide practices to eliminate disparities.

Although implementation of HIV testing in the emergency department has met with some success, one commonly cited challenge is the consent process. Kiosks offer one potential strategy to overcome this barrier. This pilot cross-sectional survey study examined patient comprehension of opt-in HIV testing consent and acceptability of using a kiosk to provide consent. Subjects were guided through a simulated consent process using a kiosk and then completed a survey of consent comprehension and acceptability of kiosk use. Subjects were 50.3% female, Black (74.4%), and had an education level of high school or less (61.3%). Subjects found the kiosk very easy or easy to use (83.9%) and reported they were very or mostly comfortable using the kiosk to consent to HIV testing (89.4%). Subjects understood the required aspects of consent: HIV testing was voluntary (93.0%, n = 185) and that refusal would not impact their care (98.5%, n = 196; 99.0%, n = 197). Following a simulated consent process, subjects demonstrated a high rate of comprehension about the vital components of HIV testing consent. Subjects reported they were comfortable using the kiosk, found the kiosk easy to use, and reported a positive experience using the kiosk to provide consent for HIV testing.

INTRODUCTION: Our goal was to reduce ordering of coagulation studies in the emergency department (ED) that have no added value for patients presenting with chest pain. We hypothesized this could be achieved via implementation of a stopgap measure in the electronic medical record (EMR). METHODS: We used a pre and post quasi-experimental study design to evaluate the impact of an EMR-based intervention on coagulation study ordering for patients with chest pain. A simple interactive prompt was incorporated into the EMR of our ED that required clinicians to indicate whether patients were on anticoagulation therapy prior to completion of orders for coagulation studies. Coagulation order frequency was measured via detailed review of randomly sampled encounters during two-month periods before and after intervention. We classified existing orders as clinically indicated or non-value added. Order frequencies were calculated as percentages, and we assessed differences between groups by chi-square analysis. RESULTS: Pre-intervention, 73.8% (76/103) of patients with chest pain had coagulation studies ordered, of which 67.1% (51/76) were non-value added. Post-intervention, 38.5% (40/104) of patients with chest pain had coagulation studies ordered, of which 60% (24/40) were non-value added. There was an absolute reduction of 35.3% (95% confidence interval [CI]: 22.7%, 48.0%) in the total ordering of coagulation studies and 26.4% (95% CI: 13.8%, 39.0%) in non-value added order placement. CONCLUSION: Simple EMR-based interactive prompts can serve as effective deterrents to indiscriminate ordering of diagnostic studies.

Background Ultrasound-guided peripheral intravenous line (USGPIV) placement is becoming an important tool in current clinical practice. Many residency programs utilize unstructured clinical observation to evaluate residents in this and other procedural skills. Simulation-based assessment permits educators to make objective, standardized observations, and may be ideal for assessment of important procedural competencies. Objective We created a simulation-based assessment tool for the skill of USGPIV placement. Methods A checklist tool was developed by a review of relevant literature and an expert review in accordance with established guidelines. Emergency medicine residents were recruited and surveyed on previous experience with USGPIV placement. Blinded, independent reviewers then utilized the checklist to assess residents as they made up to 3 attempts at USGPIV placement on a simulated pediatric arm. Results Of the 26 residents enrolled in our study, 26 participated (100%). A best attempt checklist score greater than or equal to 9 out of 10 correlated with expert performance (P < .001). Agreement between independent raters on first-attempt USGPIV placement score was determined by weighted kappa statistics to be 0.93 (95% CI 086-1.00). Conclusions The checklist assessment tool has acceptable interrater reliability and ability to distinguish performance at differing levels of competence. We propose this tool as a valuable component in the assessment of USGPIV access, and we hope this article serves as a roadmap for other educators to create similar assessment tools.

BACKGROUND: The rise of antibiotic-resistant pathogens is believed to have influenced the emergency department (ED) epidemiology and management of infectious diseases (IDs) since 2000. METHODS: Data from the National Hospital Ambulatory Medical Care Survey from 2000 to 2010 were used to examine temporal trends in the incidence of IDs presenting to EDs. Outcome measures included national visit rates, visit proportions, and antimicrobial prescriptions for all ID primary diagnoses, as well as for specific organ systems of interest (respiratory tract, skin/soft tissue, and urinary tract). RESULTS: An ID-related primary diagnosis was given in 18.3% (95% confidence interval, 17.9%-18.8%) of all ED visits during the study period. The hospitalization rate for these conditions is 7.8% (95% confidence interval, 7.3%-8.3%). The share of macrolide prescriptions for upper respiratory tract infections and lower respiratory tract infections increased by 34% and 46%, respectively, and that of quinolone prescription for lower respiratory tract infections doubled from 9% to 18.4% during the study period. Management of skin and soft tissue infections shifted from predominant use of cephalosporins to sulfonamides. For UTIs, quinolones were most commonly prescribed, with an increasing use of third-generation cephalosporins. Antibiotics were more frequently prescribed to patients who are white compared with (white: 60%, black: 57%, other races: 52%, P < .05). CONCLUSION: The changing epidemiology of IDs diagnosed in US EDs reflects national trends in emerging pathogens and drug resistance. Broad-spectrum antibiotics are being prescribed at increasing rates. There are significant demographic disparities in nationwide antibiotic prescription practices.

High operating costs challenge sustainability of successful US emergency department (ED) HIV screening programs. Free-standing registration kiosks could potentially reduce the marginal costs of ED HIV screening. We investigated incremental cost-effectiveness ratio (CER) per new HIV diagnosis for a kiosk-based approach for offering screening at ED registration versus a testing staff-based approach to offer testing at the bedside. A rapid oral-fluid HIV screening program, instituted in a US ED since 2005, had a rate of new HIV diagnosis 0.16% in 2012. A two-phase quasi experimental design, including a testing staff-based approach to offer testing at the bedside (Phase I, August and September 2011) and a kiosk-based approach to offer testing at ED registration (Phase II, December 2011 and January 2012), was performed. CER per new HIV diagnosis was defined as total cost of the screening program divided by number of newly diagnosed cases. Costs included screening program personnel (study coordinator, testing staff, and kiosk helpers), diagnostic assays (rapid and confirmatory tests), and kiosks (2 kiosks, software, and IT consulting fees). Sensitivity analyses were performed. Data from our dedicated testing staff (DTS) program (Phase I) resulted in an estimated 5434 patients tested in one year and 9 newly diagnosed HIV-infected patients (95% CI: 3, 18). Data from the kiosk program (Phase II), resulted in a projected 4571 ED patients tested in one year and 21 newly diagnosed HIV-infected patients (95% CI: 4, 70). The overall cost was $ 201,433 for the DTS program, versus $292,008 for the kiosk program. Incremental CER per new HIV diagnosis for kiosk-based approach was $7523 (range: $1780-90,025 by sensitivity analysis). Our pilot data demonstrated that the use of kiosks for HIV screening was potentially more cost-effective than a testing staff-based bedside approach.

OBJECTIVES: Herpes simplex virus type 2 (HSV-2) is a common sexually transmitted disease, but there is limited data on its epidemiology among urban populations. The urban Emergency Department (ED) is a potential venue for surveillance as it predominantly serves an inner city minority population. We evaluate the seroprevalence and factors associated with HSV-2 infection among patients attending the Johns Hopkins Hospital Adult Emergency Department (JHH ED). METHODS: An identity unlinked-serosurvey was conducted between 6/2007 and 9/2007 in the JHH ED; sera were tested by the Focus HerpeSelect ELISA. Prevalence risk ratios (PRR) were used to determine factors associated with HSV-2 infection. RESULTS: Of 3,408 serum samples, 1,853 (54.4%) were seropositive for HSV-2. Females (adjPRR â=â1.47, 95% CI 1.38-1.56), non-Hispanic blacks (adjPRR â=â2.03, 95% CI 1.82-2.27), single (adjPRR â=â1.15, 95% CI 1.07-1.25), divorced (adjPRR â=â1.28, 95% CI 1.15-1.41), and unemployed patients (adjPRR â=â1.13, 95% CI 1.05-1.21) had significantly higher rates of HSV-2 infection. Though certain zip codes had significantly higher seroprevalence of HSV-2, this effect was completely attenuated when controlling for age and gender. CONCLUSIONS: Seroprevalence of HSV-2 in the JHH ED was higher than U.S. national estimates; however, factors associated with HSV-2 infection were similar. The high seroprevalence of HSV-2 in this urban ED highlights the need for targeted testing and treatment. Cross-sectional serosurveys in the urban ED may help to examine the epidemiology of HSV-2.

INTRODUCTION: The goal of an Emergency Medical Services (EMS) system is to prevent needless death or disability from time-sensitive disease processes. Despite growing evidence that these processes contribute significantly to mortality in low- and middle- income countries (LMICs), there has been little focus on the development of EMS systems in poor countries. Problem The objective of this study was to understand the utilization pattern of a newly-implemented EMS system in Ruhiira, Uganda. METHODS: An EMS system based on community priorities was implemented in rural Uganda in 2009. Six months of ambulance logs were reviewed. Patient, transfer, and clinical data were extracted and analyzed. RESULTS: In total, 207 cases were reviewed. Out of all transfers, 66% were for chief complaints that were obstetric related, while 12% were related to malaria. Out of all activations, 77.8% were for female patients. Among men, 34% and 28% were related to malaria and trauma, respectively. The majority of emergency transfers were from district to regional hospitals, including 52% of all obstetric transfers, 65% of malaria transfers, and 62% of all trauma transfers. There was no significant difference in the call to arrival on scene time, the time to scene or the scene to treatment time during the day and night (P > .05). Cost-benefit analysis revealed a cost of $89.95 per life saved with an estimated $0.93/capita to establish the system and $0.09/capita/year to maintain the system. CONCLUSION: Contrary to current belief, EMS systems in rural Africa can be affordable and highly utilized, particularly for life-threatening, nontrauma complaints.

OBJECTIVES: Dizziness and vertigo account for roughly 4% of chief symptoms in the emergency department (ED). Little is known about the aggregate costs of ED evaluations for these patients. The authors sought to estimate the annual national costs associated with ED visits for dizziness. METHODS: This cost study of adult U.S. ED visits presenting with dizziness or vertigo combined public-use ED visit data (1995 to 2009) from the National Hospital Ambulatory Medical Care Survey (NHAMCS) and cost data (2003 to 2008) from the Medical Expenditure Panel Survey (MEPS). We calculated total visits, test utilization, and ED diagnoses from NHAMCS. Diagnosis groups were defined using the Healthcare Cost and Utilization Project's Clinical Classifications Software (HCUP-CCS). Total visits and the proportion undergoing neuroimaging for future years were extrapolated using an autoregressive forecasting model. The average ED visit cost-per-diagnosis-group from MEPS were calculated, adjusting to 2011 dollars using the Hospital Personal Health Care Expenditures price index. An overall weighted mean across the diagnostic groups was used to estimate total national costs. Year 2011 data are reported in 2011 dollars. RESULTS: The estimated number of 2011 US ED visits for dizziness or vertigo was 3.9 million (95% confidence interval [CI] = 3.6 to 4.2 million). The proportion undergoing diagnostic imaging by computed tomography (CT), magnetic resonance imaging (MRI), or both in 2011 was estimated to be 39.9% (39.4% CT, 2.3% MRI). The mean per-ED-dizziness-visit cost was $1,004 in 2011 dollars. The total extrapolated 2011 national costs were $3.9 billion. HCUP-CCS key diagnostic groups for those presenting with dizziness and vertigo included the following (fraction of dizziness visits, cost-per-ED-visit, attributable annual national costs): otologic/vestibular (25.7%; $768; $757 million), cardiovascular (16.5%, $1,489; $941 million), and cerebrovascular (3.1%; $1059; $127 million). Neuroimaging was estimated to account for about 12% of the total costs for dizziness visits in 2011 (CT scans $360 million, MRI scans $110 million). CONCLUSIONS: Total U.S. national costs for patients presenting with dizziness to the ED are substantial and are estimated to now exceed $4 billion per year (about 4% of total ED costs). Rising costs over time appear to reflect the rising prevalence of ED visits for dizziness and increased rates of imaging use. Future economic studies should focus on the specific breakdown of total costs, emphasizing areas of high cost and use that might be safely reduced.

OBJECTIVES: The objective was to describe the proportions of successful linkage to care (LTC) and identify factors associated with LTC among newly diagnosed human immunodeficiency virus (HIV)-positive patients, from two urban emergency department (ED) rapid HIV screening programs. METHODS: This was a retrospective analysis of programmatic data from two established urban ED rapid HIV screening programs between November 2005 and October 2009. Trained HIV program assistants interviewed all patients tested to gather risk behavior data using a structured data collection instrument. Reactive results were confirmed by Western blot testing. Patients were provided with scheduled appointments at HIV specialty clinics at the institutions where they tested positive within 30 days of their ED visit. "Successful" LTC was defined as attendance at the HIV outpatient clinic within 30 days after HIV diagnosis, in accordance with the ED National HIV Testing Consortium metric. "Any" LTC was defined as attendance at the outpatient HIV clinic within 1 year of initial HIV diagnosis. Multivariate logistic regression was performed to determine factors associated with any LTC or successful LTC. RESULTS: Of the 15,640 tests administered, 108 (0.7%) were newly identified HIV-positive cases. Nearly half (47.2%) of the patients had been previously tested for HIV. Successful LTC occurred in 54% of cases; any LTC occurred in 83% of cases. In multivariate analysis, having public medical insurance and being self-pay were negatively associated with successful LTC (odds ratio [OR] = 0.33, 95% confidence interval [CI] = 0.12 to 0.96; OR = 0.34, 95% CI = 0.13 to 0.89, respectively); being female and having previously tested for HIV was negatively associated with any LTC (OR = 0.30, 95% CI = 0.10 to 0.93; OR = 0.23, 95% CI = 0.07 to 0.77, respectively). CONCLUSIONS: In spite of dedicated resources for arranging LTC in the ED HIV testing programs, nearly 50% of patients did not have successful LTC (i.e., LTC occurred at >30 days), although >80% of patients were LTC within 1 year of initial diagnosis. Further evaluation of the barriers associated with successful LTC for those with public insurance and self-pay is warranted.

BACKGROUND: Submission of self-obtained vaginal samples (SOVs) collected at home could remove barriers that women face in getting tested for sexually transmitted infections (STIs). Internet recruitment of SOVs is highly acceptable. METHODS: Sexually active women ≥14 years were recruited by an educational Internet program, available at: www.iwantthekit.org (IWTK), which offered free testing for trichomonas as part of a panel, which also offered testing for chlamydia and gonorrhea. Kits were ordered online, SOVs were sent through US mail to the laboratory, and tested by nucleic acid amplification tests. Demographics and sexual risk factors were accessed by questionnaires. Women called or were contacted to receive their results. RESULTS: Of women requesting kits, 1525 (43%) returned swabs by mail. In all, 61% were <25 years, 52% were black, and 80% were single. Vaginal discharge was reported by 44%, prevalence for trichomonas was 10% (10% for chlamydia, 1% for gonorrhea), and 18% had at least one prevalent STI. Multivariate logistic regression demonstrated several significantly associated risks factors as follows: adjusted odds ratio for black race was 2.69; for residence of Illinois, 3.85; for not having health insurance, 1.57; for lack of a bachelor's degree, 5.53; for having 2 to 15 partners, 1.60; for having ≥16 partners in previous year, 3.51; for being bisexual, 2.0; for not always using condoms, 3.04; and for having a partner who had a previous STI, 1.71. Age was not associated with trichomonas infection. All infected women were treated. CONCLUSIONS: A high prevalence of trichomonas and high sexual risk factors were demonstrated. Internet recruitment was a useful method of screening women for trichomonas infection.

OBJECTIVE: We compare the outcomes and costs of alternative staffing models for an emergency department (ED) rapid HIV testing program. METHODS: A rapid oral-fluid HIV testing program was instituted in an inner-city ED in 2005. Three staffing models were compared during 24.5 months: indigenous medical staff only, exogenous staff only, or exogenous staff plus medical staff (hybrid). Personnel obtained written consent and provided brief pretest counseling, obtained kits, collected specimens, returned specimens to the ED satellite laboratory, and performed posttest counseling and referral to care. Cost analysis was performed to estimate cost per patient tested and cost per patient linked to care. RESULTS: Overall, 44 of 2,958 (1.5%) patients tested received confirmed positive results and 30 (68%) were linked to care. The exogenous staff only model yielded the highest number tested per month (587), and indigenous medical staff only yielded the lowest (57). Significantly higher positivity rates were found in both indigenous medical staff only (2.2%) and hybrid (2.0%) models versus the exogenous staff only model (0.6%) (prevalence rate ratio: 3.7 [95% confidence interval {CI}1.5 to 9.3] versus 3.4 [95% CI 1.5 to 7.8], respectively). All patients with confirmed positive results were linked to care in the indigenous medical staff only model but only approximately 60% were linked to care in the 2 other models (linked to care rate ratio versus exogenous staff only: 1.8 [95% CI 1.1 to 4.4]; versus hybrid: 1.7 [95% CI 1.2 to 2.5]). The indigenous medical staff only model had the highest cost ($109) per patient tested, followed by the hybrid ($87) and the exogenous staff only ($39). However, the indigenous medical staff only model had the lowest cost ($4,937) per patient linked to care, followed by the hybrid ($7,213) and exogenous staff only ($11,454). CONCLUSION: The exogenous staff only model tested the most patients at the least cost per patient tested. The indigenous medical staff only model identified the fewest patients with unrecognized HIV infection and had the highest cost per patient tested but the lowest cost per patient linked to care.
