Database derived from an electronic medical record-based surveillance network of US emergency department patients with acute respiratory illness. BMC Med Inform Decis Mak 2023; 23:224. [PMID: 37848896 PMCID: PMC10580574 DOI: 10.1186/s12911-023-02310-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 09/27/2023] [Indexed: 10/19/2023] Open
Abstract
BACKGROUND For surveillance of episodic illness, the emergency department (ED) represents one of the largest interfaces for generalizable data about segments of the US public experiencing a need for unscheduled care. This protocol manuscript describes the development and operation of a national network linking symptom, clinical, laboratory and disposition data that provides a public database dedicated to the surveillance of acute respiratory infections (ARIs) in EDs. METHODS The Respiratory Virus Laboratory Emergency Department Network Surveillance (RESP-LENS) network includes 26 academic investigators, from 24 sites, with 91 hospitals, and the Centers for Disease Control and Prevention (CDC) to survey viral infections. All data originate from electronic medical records (EMRs) accessed by structured query language (SQL) coding. Each Tuesday, data are imported into the standard data form for ARI visits that occurred the prior week (termed the index file); outcomes at 30 days and ED volume are also recorded. Up to 325 data fields can be populated for each case. Data are transferred from sites into an encrypted Google Cloud Platform, then programmatically checked for compliance, parsed, and aggregated into a central database housed on a second cloud platform prior to transfer to CDC. RESULTS As of August, 2023, the network has reported data on over 870,000 ARI cases selected from approximately 5.2 million ED encounters. Post-contracting challenges to network execution have included local shifts in testing policies and platforms, delays in ICD-10 coding to detect ARI cases, and site-level personnel turnover. The network is addressing these challenges and is poised to begin streaming weekly data for dissemination. CONCLUSIONS The RESP-LENS network provides a weekly updated database that is a public health resource to survey the epidemiology, viral causes, and outcomes of ED patients with acute respiratory infections.

The Determining Effective Testing in Emergency Departments and Care Coordination on Treatment Outcomes (DETECT) for Hepatitis C (Hep C) Linkage-to-Care Trial: rationale and design of an emergency department-based randomized clinical trial of linkage-to-care strategies for hepatitis C. Trials 2023; 24:63. [PMID: 36707909 PMCID: PMC9880363 DOI: 10.1186/s13063-022-07018-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 12/15/2022] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Hepatitis C (HCV) poses a major public health problem in the USA. While early identification is a critical priority, subsequent linkage to a treatment specialist is a crucial step that bridges diagnosed patients to treatment, cure, and prevention of ongoing transmission. Emergency departments (EDs) serve as an important clinical setting for HCV screening, although optimal methods of linkage-to-care for HCV-diagnosed individuals remain unknown. In this article, we describe the rationale and design of The Determining Effective Testing in Emergency Departments and Care Coordination on Treatment Outcomes (DETECT) for Hepatitis C (Hep C) Linkage-to-Care Trial. METHODS The DETECT Hep C Linkage-to-Care Trial will be a single-center prospective comparative effectiveness randomized two-arm parallel-group superiority trial to test the effectiveness of linkage navigation and clinician referral among ED patients identified with untreated HCV with a primary hypothesis that linkage navigation plus clinician referral is superior to clinician referral alone when using treatment initiation as the primary outcome. Participants will be enrolled in the ED at Denver Health Medical Center (Denver, CO), an urban, safety-net hospital with approximately 75,000 annual adult ED visits. This trial was designed to enroll a maximum of 280 HCV RNA-positive participants with one planned interim analysis based on methods by O'Brien and Fleming. This trial will further inform the evaluation of cost effectiveness, disparities, and social determinants of health in linkage-to-care, treatment, and disease progression. DISCUSSION When complete, the DETECT Hep C Linkage-to-Care Trial will significantly inform how best to perform linkage-to-care among ED patients identified with HCV.

The Determining Effective Testing in Emergency Departments and Care Coordination on Treatment Outcomes (DETECT) for Hepatitis C (Hep C) Screening Trial: rationale and design of a multi-center pragmatic randomized clinical trial of hepatitis C screening in emergency departments. Trials 2022; 23:354. [PMID: 35468807 PMCID: PMC9036509 DOI: 10.1186/s13063-022-06265-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Accepted: 03/31/2022] [Indexed: 12/24/2022] Open
Abstract
Background Early identification of HCV is a critical health priority, especially now that treatment options are available to limit further transmission and provide cure before long-term sequelae develop. Emergency departments (EDs) are important clinical settings for HCV screening given that EDs serve many at-risk patients who do not access other forms of healthcare. In this article, we describe the rationale and design of The Determining Effective Testing in Emergency Departments and Care Coordination on Treatment Outcomes (DETECT) for Hepatitis C (Hep C) Screening Trial. Methods The DETECT Hep C Screening Trial is a multi-center prospective pragmatic randomized two-arm parallel-group superiority trial to test the comparative effectiveness of nontargeted and targeted HCV screening in the ED with a primary hypothesis that nontargeted screening is superior to targeted screening when identifying newly diagnosed HCV. This trial will be performed in the EDs at Denver Health Medical Center (Denver, CO), Johns Hopkins Hospital (Baltimore, MD), and the University of Mississippi Medical Center (Jackson, MS), sites representing approximately 225,000 annual adult visits, and designed using the PRECIS-2 framework for pragmatic trials. When complete, we will have enrolled a minimum of 125,000 randomized patient visits and have performed 13,965 HCV tests. In Denver, the Screening Trial will serve as a conduit for a distinct randomized comparative effectiveness trial to evaluate linkage-to-HCV care strategies. All sites will further contribute to embedded observational studies to assess cost effectiveness, disparities, and social determinants of health in screening, linkage-to-care, and treatment for HCV. Discussion When complete, The DETECT Hep C Screening Trial will represent the largest ED-based pragmatic clinical trial to date and all studies, in aggregate, will significantly inform how to best perform ED-based HCV screening.

Abstract
BACKGROUND Chlamydia trachomatis (CT) infection remains highly prevalent, and young women are disproportionately affected. Most CT-infected women are asymptomatic, and their infection often goes unrecognized and untreated. We hypothesized that testing for active CT infection with molecular diagnostics and obtaining a reported history of CT infection underestimate the prevalence of current and past CT infection, and incorporating serum CT antibody testing in addition to these other prevalence measures would generate more accurate estimates of the prevalence of CT infection in asymptomatic young women. METHODS We enrolled 362 asymptomatic women aged 16 to 29 years at 4 different clinical settings in Birmingham, AL, between August 2016 and January 2020 and determined the prevalence of CT infection based on having 1 or more of the following prevalence measures: an active urogenital CT infection based on molecular testing, reported prior CT infection, and/or being CT seropositive. Multivariable regression analysis was used to determine predictors of the prevalence of CT infection after adjustment for participant characteristics. RESULTS The prevalence of CT infection was 67.7% (95% confidence interval, 62.6%-72.5%). Addition of CT antibody testing to the other individual prevalence measures more than doubled the CT infection prevalence. Non-Hispanic Black race, reported prior gonorrhea, and reported prior trichomoniasis predicted a higher prevalence of CT infection. CONCLUSIONS More than half of women were unaware of ever having CT infection, suggesting many were at risk for CT-associated reproductive complications. These data reinforce the need to adhere to chlamydia screening guidelines and to increase screening coverage in those at risk.

Abstract
Mycoplasma genitalium (MG) infection, a sexually transmitted infection (STI), causes cervicitis and may cause reproductive sequelae and adverse pregnancy outcomes. Some MG-infected women report dysuria, a symptom frequently attributed to urinary tract infection (UTI). Given potential MG-associated morbidity and the likelihood that UTI treatment would be ineffective in eradicating MG, an improved understanding of MG infection frequency and clinical significance in young women reporting dysuria is needed. We conducted MG testing on stored urogenital specimens collected in a pilot study on frequency of STIs in young women presenting to an emergency department for dysuria evaluation and performed a literature review on MG infection frequency in women reporting dysuria. Among 25 women presenting for dysuria evaluation in our pilot study, 6 (24.0%) had MG detected and one-third had co-infection with chlamydia and one-third with trichomoniasis; half with MG detected did not receive an antibiotic with known efficacy against MG, while the other half received azithromycin. In five studies identified in the literature review, dysuria was reported by 7%-19% of women and MG detected in 5%-22%. MG infection is common in young women with dysuria and empiric UTI treatment may not be effective against MG. Studies evaluating the clinical significance of MG infection in women reporting dysuria are needed.

Human Papillomavirus Awareness, Vaccine Status, and Risk Factors in Female Emergency Patients. West J Emerg Med 2020; 21:203-208.

Abstract
Introduction A vaccine targeting high-risk human papillomavirus (HPV) strains can effectively prevent HPV-associated cervical cancer risk. However, many girls and women do not receive the vaccine, more often those impacted by health disparities associated with race and/or socioeconomic status. This same disparate population has also been shown to be at higher risk for cervical cancer. Many of these women also rely on the emergency department (ED) as a safety net for their healthcare. This study sought to gather information pertaining to HPV and cervical cancer risk factors, awareness of HPV and the vaccine, as well as HPV vaccine uptake in female patients presenting to an ED. Methods We obtained 81 surveys completed by female ED patients. Demographics included age, race, income, insurance status, primary care provider status, and known cervical-cancer risk factors. Subsequent survey questions explored respondents’ knowledge, familiarity, and attitudes regarding HPV, cervical cancer, and the HPV vaccine, including vaccination uptake rates. We analyzed data using descriptive statistics and Fisher’s exact test. Results Approximately one in seven respondents (14.8%) had never previously heard of HPV and 32.1% were unaware of the existence of a HPV vaccine. Minority patients, including those who were Black and Hispanic patients, low income patients, and uninsured and publicly insured patients were less likely to be aware of HPV and the vaccine and likewise were less likely to be offered and receive the vaccine. More than 60% of all respondents (61.3%) had never previously been offered the vaccine, and only 24.7% of all respondents had completed the vaccine series. Conclusion Female ED patients may represent an at-risk cohort with relatively low HPV awareness and low HPV vaccine uptake. The ED could represent a novel opportunity to access and engage high-risk HPV populations.

Predictors of linkage to care for a nontargeted emergency department hepatitis C screening program. Am J Emerg Med 2019; 38:1396-1401. [PMID: 31836342 DOI: 10.1016/j.ajem.2019.11.034] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2019] [Revised: 11/18/2019] [Accepted: 11/18/2019] [Indexed: 01/23/2023] Open
Abstract
OBJECTIVE We implemented a nontargeted, opt-out HCV testing and linkage to care (LTC) program in an academic tertiary care emergency department (ED). Despite research showing the critical role of ED-based HCV testing programs, predictors of LTC have not been defined for patients identified through the nontargeted ED testing strategy. In order to optimize health outcomes for patients with HCV, we sought to identify predictors of LTC failure. METHODS This was a retrospective cohort study of adult patients who were tested for HCV in the ED between August 2015 and September 2018 and were confirmed to have chronic HCV infection through RNA testing. We used logistic regression to assess the relationship between candidate predictors and the primary outcome, LTC failure, which was defined as a patient not being seen by an HCV treating provider after discharge from the ED. RESULTS Of 53,297 patients tested, 1,674 (3.1%) had HCV on confirmatory testing, and 355 (21%) linked to care. Predictors of LTC failure included younger age (OR 0.96, 95% CI 0.95-0.97), white race (OR 1.65, 95% CI 1.23-2.22), homelessness (OR 1.91, 95% CI 1.19-3.08), substance use (OR 1.77, 95% CI 1.34-2.34), and comorbid psychiatric illness (OR 2.16, 95% CI 1.59-2.94). Patients with significant medical comorbidities (OR 0.57, 95% CI 0.41-0.78) or HIV co-infection (OR 0.11, 95% CI 0.03-0.46) were less likely to experience LTC failure. CONCLUSIONS One in five HCV-infected patients identified by ED-based nontargeted testing successfully linked to an HCV treating provider. Predictors of LTC failure may guide the development of targeted interventions to improve LTC success.

Abstract
INTRODUCTION Residents may differentially experience high stress and poor sleep across multiple post-graduate years (PGYs), negatively affecting safety. This study characterized sleep and stress among medical and surgical residents across multiple PGYs and at specific times surrounding duty. METHOD Thirty-two medical and surgical residents (Mage = 28.6 years; 56% male) across PGYs 1-5 participated in 3 appointments (immediately before duty, after duty, and on an off day) providing 96 data points. Sleep, stress, and occupational fatigue were measured by both self-report and objectively (actigraphy, salivary coritsol). RESULTS Residents averaged 7 h of actigraphy-estimated sleep per night but varied ±3 h day-to-day. Residents reported clinically poor sleep quality. Life stress decreased by PGY-2. All residents averaged elevated life stress values. Poor sleep quality did not differ among PGY cohorts. DISCUSSION Poor sleep quality is similar between early residency cohorts (PGY-1) and later residency cohorts (PGY-3+). Persistent fatigue is highest in later residency cohorts. Even the most experienced residents may struggle with persisting fatigue. Current hour policies may have shortcomings in addressing this risk.

Attitudes and availability: A comparison of naloxone dispensing across chain and independent pharmacies in rural and urban areas in Alabama. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2019; 74:229-235. [PMID: 31698165 DOI: 10.1016/j.drugpo.2019.09.021] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Revised: 09/27/2019] [Accepted: 09/30/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND Fatal opioid overdoses remain the leading cause of accidental deaths in the United States, which have contributed to implementation of standing order laws that allow pharmacists to dispense naloxone to patients. Although pharmacy distribution of naloxone is a promising approach to increase access to this intervention, understanding barriers preventing greater uptake of this service is needed. METHODS Data for the current study were collected via telephone survey assessing the availability of various formulations of naloxone at chain and independent pharmacies in rural and urban areas in Birmingham, Alabama (N = 222). Pharmacists' attitudes toward naloxone and potential barriers of pharmacy naloxone distribution were also assessed. One-way analysis of variance (ANOVA) and logistic regression analyses were utilized to examine differences in stocking of naloxone in chain and independent pharmacies and to determine predictors of the number of kits dispensed by pharmacies. RESULTS Independent pharmacies were less likely to have naloxone in stock, especially those in rural areas. Furthermore, rural pharmacies required more time to obtain all four formulations of naloxone, and offered less extensive training on naloxone use. Pharmacists endorsing the belief that naloxone allows avoidance of emergent treatment in an overdose situation was associated with fewer dispensed kits by the pharmacies. Over 80% of pharmacists endorsed at least one negative belief about naloxone (e.g., allowing riskier opioid use). Pharmacists noted cost to patients and the pharmacy as contributing to not dispensing more naloxone kits. CONCLUSION The current study demonstrates the lower availability of naloxone stocked at pharmacies in independent versus chain pharmacies, particularly in rural communities. This study also highlights several barriers preventing greater naloxone dispensing including pharmacists' attitudes and costs of naloxone. The potential benefit of standing order laws is not being fully actualized due to the structural and attitudinal barriers identified in this study. Strategies to increase naloxone access through pharmacy dispensing are discussed.

Abstract
INTRODUCTION Drug overdoses are the leading cause of accidental death in the United States. It is imperative to explore predictors of opioid overdose in order to facilitate targeted treatment and prevention efforts. The present study was conducted as an exploratory examination of the factors associated with having a past opioid overdose. METHODS Participants (N = 244) from substance treatment facilities, inpatient services following ER admittance, or involved within the drug court system and who reported opioid use in the past 6 months were recruited in this study. Measures of opioid use and history were used to determine characteristics associated with previous experience of a non-fatal opioid overdose. RESULTS Opioid users who were Caucasian and used a combination of prescription opioids and heroin were more likely to have experienced a prior overdose. Opioid user characteristics associated with greater odds of experiencing a prior overdose included: witnessing a friend overdose (OR 4.21), having chronic hepatitis C virus (HCV) infection (OR 2.44), reporting a higher frequency of buprenorphine treatment episodes (OR 1.55), and having a higher frequency of witnessing others overdose (OR 1.42). Greater frequency of methadone treatment episodes was related to decreased odds of experiencing an overdose (OR 0.67). CONCLUSION Overall, this study demonstrated certain demographic and drug use factors associated with elevated risk for an overdose. Understanding the risk factors associated with drug overdose can lead to targeted naloxone training and distribution to prevent fatal overdoses.

Abstract
BACKGROUND Emergency departments (EDs) are high-yield sites for hepatitis C virus (HCV) screening, but data regarding linkage to care (LTC) determinants are limited. METHODS Between September 2013 and June 2014, 4371 baby boomers unaware of their HCV status presented to the University of Alabama at Birmingham ED and underwent opt-out screening. A linkage coordinator facilitated referrals for positive cases. Demographic data, International Classification of Diseases, Ninth Revision codes, and clinic visits were collected, and patients were (retrospectively) followed up until February 2015. Linkage to care was defined as an HCV clinic visit within the hospital system. RESULTS Overall, 332 baby boomers had reactive HCV antibody and detectable plasma ribonucleic acid. The mean age was 57.3 years (standard deviation = 4.8); 70% were male and 61% were African Americans. Substance abuse (37%) and psychiatric diagnoses (30%) were prevalent; 9% were identified with cirrhosis. During a median follow-up of 433 days (interquartile range, 354-500), 117 (35%) linked to care and 48% needed inpatient care. In multivariable analysis, the odds of LTC failure were significantly higher for white males (adjusted odds ratio [aOR], 2.57; 95% confidence interval [CI], 1.03-6.38) and uninsured individuals (aOR, 5.16; 95% CI, 1.43-18.63) and lower for patients with cirrhosis (aOR, 0.36; 95% CI, 0.14-0.92) and access to primary care (aOR, 0.20; 95% CI, 0.10-0.41). CONCLUSIONS In this cohort of baby boomers with newly diagnosed HCV in the ED, only 1 in 3 were linked to HCV care. Although awareness of HCV diagnosis remains important, intensive strategies to improve LTC and access to curative therapy for diagnosed individuals are needed.

Abstract
OBJECTIVE The Centers for Disease Control and Prevention has recommended emergency department (ED) opt-out HIV screening since 2006. Routine screening can prove challenging due to the ED's complexity and competing priorities. This study examined the implementation and evolution of a routine, integrated, opt-out HIV screening program at an urban academic ED in Alabama since August 2011. METHODS ED routine, opt-out HIV screening was implemented as a standard of care in September 2011. To describe the outcomes and escalation of the screening program, data analyses were performed from three separate data queries: (1) encounter-level HIV screening questionnaire and test results from September 21, 2011, through December 31, 2013; (2) test-level, fourth-generation HIV results from July 9 through December 31, 2013; and (3) daily HIV testing rates and trends from September 9, 2011, through June 30, 2014. RESULTS Of the 46,385 HIV screening tests performed, 252 (0.5%) were confirmed to be positive. Acute HIV infection accounted for 11.8% of all HIV patients identified using the fourth-generation HIV screening assay. Seventy-six percent of confirmed HIV-positive patients had successful linkage to care. Implementation of fourth-generation HIV instrument-based testing resulted in a 15.0% decline in weekly HIV testing rates. Displacement of nursing provider HIV test offers from triage to the bedside resulted in a 31.6% decline in weekly HIV testing rates. CONCLUSION This program demonstrated the capacity for high-volume, routine, opt-out HIV screening. Evolving ED challenges require program monitoring and adaptation to sustain scalable HIV screening in EDs.

Abstract
Introduction The clinical presentation of genital Chlamydia trachomatis infection (chlamydia) in women is often indistinguishable from a urinary tract infection. While merited in the setting of dysuria, emergency department (ED) clinicians do not routinely test for chlamydia in women. The primary aim of our study was to evaluate the frequency of chlamydia testing among women presenting to the ED with dysuria. Methods We conducted a retrospective chart review of women 19–25 years of age presenting with dysuria to an urban ED and who had been coded with urinary tract infection (UTI) as their primary diagnosis (ICD-9 599.0) from October 2005 to March 2011. We excluded women who were pregnant, had underlying anatomical or neurological urinary system pathology, had continuation of symptoms from UTI or a sexually transmitted infection (STI) diagnosed elsewhere, or were already on antibiotics for a UTI or STI. We identified the rates of sexual history screening, pelvic examination and chlamydia assay testing and evaluated predictors using univariate and multivariate analyses. Results Of 280 women with dysuria and a UTI diagnosis, 17% were asked about their sexual history, with 94% reporting recent sexual activity. Pelvic examination was performed in 23%. We were unable to determine the overall chlamydia prevalence as only 20% of women in the cohort were tested. Among the 20% of women tested for chlamydia infection, 21% tested positive. Only 42% of chlamydia-positive women were prescribed treatment effective for chlamydia (azithromycin or doxycycline) at their visit; the remaining were prescribed UTI treatment not effective against chlamydia. Predictors of sexual history screening included vaginal bleeding (OR 5.4, 95% CI=1.5 to 19.6) and discharge (OR 2.8, 95% CI=1.1 to 6.9). Predictors of a pelvic examination being performed included having a complaint of vaginal discharge (OR 11.8, 95% CI=4.2 to 32.9), a sexual history performed (OR 2.5, 95% CI=1.1 to 5.8), abdominal pain (OR 2.2, 95% CI=1.1 to 4.4), or pelvic pain (OR 15.3, 95% CI=2.5 to 92.2); a complaint of urinary frequency was associated with a pelvic examination not being performed (OR 0.34, 95% CI=0.13 to 0.86). Conclusion Sexual histories, pelvic examinations, and chlamydia testing were not performed in the majority of women presenting with dysuria and diagnosed with UTI in the ED. The performance of a sexual history along with the availability of self-administered vaginal swab and first-void urine-based chlamydia tests may increase identification of chlamydia infection in women with dysuria.

Unrecognized chronic hepatitis C virus infection among baby boomers in the emergency department. Hepatology 2015; 61:776-82. [PMID: 25179527 DOI: 10.1002/hep.27410] [Citation(s) in RCA: 98] [Impact Index Per Article: 10.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2014] [Revised: 07/25/2014] [Accepted: 08/28/2014] [Indexed: 12/20/2022]
Abstract
UNLABELLED The Centers for Disease Control and Prevention and U.S. Preventive Services Task Force have highlighted public screening as an essential strategy for increasing hepatitis C virus (HCV) detection in persons born between 1945 and 1965 ("baby boomers"). Because earlier HCV screening efforts have not targeted emergency department (ED) baby boomer patients, we describe early experience with integrated opt-out HCV antibody (Ab) screening of medically stable baby boomers presenting to an urban academic ED. We performed HCV Ab testing 24 hours per day and confirmed positive test results using polymerase chain reaction (PCR). The primary outcome was prevalence of unrecognized HCV infection. Among 2,325 unique HCV-unaware baby boomers, 289 (12.7%) opted out of HCV screening. We performed HCV Ab tests on 1,529 individuals, of which 170 (11.1%) were reactive. Among Ab reactive cases, follow-up PCR was performed on 150 (88.2%), of which 102 (68.0%) were confirmed RNA positive. HCV Ab reactivity was more likely in males compared to females (14.7% vs. 7.4%; P<0.001), African Americans compared to whites (13.3% vs. 8.8%; P=0.010), and underinsured/ uninsured patients compared to insured patients (16.8%/16.9% vs. 5.0%; P=0.001). Linkage-to-care service activities were recorded for 100 of the 102 confirmed cases. Overall, 54 (54%) RNA-positive individuals were successfully contacted by phone within five call-back attempts. We confirmed initial follow-up appointments for 38 (70.4%) RNA-positive individuals successfully contacted, and 21 (55.3%) individuals with confirmed appointments attended their initial visit with a liver specialist; 3 (7.9%) are awaiting an upcoming scheduled appointment. CONCLUSION We observed high prevalence of unrecognized chronic HCV infection in this series of baby boomers presenting to the ED, highlighting the ED as an important venue for high-impact HCV screening and linkage to care.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is a major public health problem in the United States. Although prior studies have evaluated the HCV-related healthcare burden, these studies examined a single treatment setting and did not account for the growing "baby boomer" population (individuals born during 1945-1965). METHODS Data from the National Ambulatory Medical Care Survey, the National Hospital Ambulatory Medical Care Survey, and the Nationwide Inpatient Sample were analyzed. We sought to characterize healthcare utilization by individuals infected with HCV in the United States, examining adult (≥18 years) outpatient, emergency department (ED), and inpatient visits among individuals with HCV diagnosis for the period 2001-2010. Key subgroups included persons born before 1945 (older), between 1945 and 1965 (baby boomer), and after 1965 (younger). RESULTS Individuals with HCV infection were responsible for >2.3 million outpatient, 73 000 ED, and 475 000 inpatient visits annually. Persons in the baby boomer cohort accounted for 72.5%, 67.6%, and 70.7% of care episodes in these settings, respectively. Whereas the number of outpatient visits remained stable during the study period, inpatient admissions among HCV-infected baby boomers increased by >60%. Inpatient stays totaled 2.8 million days and cost >$15 billion annually. Nonwhites, uninsured individuals, and individuals receiving publicly funded health insurance were disproportionately affected in all healthcare settings. CONCLUSIONS Individuals with HCV infection are large users of outpatient, ED, and inpatient health services. Resource use is highest and increasing in the baby boomer generation. These observations illuminate the public health burden of HCV infection in the United States.

Taxation, smuggling and demand for cigarettes in Canada: evidence from time-series data. JOURNAL OF HEALTH ECONOMICS 1997; 16:287-301.

Abstract
This study analyzes Canadian cigarette consumption and taxation between 1980 and 1994, a period in which there have been large price rises and declines, and a dramatic increase in the consumption of contraband tobacco products. We examine elasticities of legal cigarette sales and total sales (including contraband) with respect to the price of legal cigarettes and various other factors. The growth of the contraband market since 1987 appears to have created two classes of cigarette--taxed and untaxed--with responses to changes in the legal price that are respectively higher, and lower, than was previously the case. The sensitivity of total cigarette sales to the taxation instrument is much lower than it would appear from sales of taxed cigarettes alone.
