Estimation of the prevalence of undiagnosed and diagnosed HIV in an urban emergency department.

ABSTRACT:

Objective

To estimate the prevalence of undiagnosed HIV, the prevalence of diagnosed HIV, and proportion of HIV that is undiagnosed in populations with similar demographics as the Universal Screening for HIV in the Emergency Room (USHER) Trial and the Brigham and Women's Hospital (BWH) Emergency Department (ED) in Boston, MA. We also sought to estimate these quantities within demographic and risk behavior subgroups.

Method

We used data from the USHER Trial, which was a randomized clinical trial of HIV screening conducted in the BWH ED. Since eligible participants were HIV-free at time of enrollment, we were able to calculate the prevalence of undiagnosed HIV. We used data from the Massachusetts Department of Public Health (MA/DPH) to estimate the prevalence of diagnosed HIV since the MA/DPH records the number of persons within MA who are HIV-positive. We calculated the proportion of HIV that is undiagnosed using these estimates of the prevalence of undiagnosed and diagnosed HIV. Estimates were stratified by age, sex, race/ethnicity, history of testing, and risk behaviors.

Results

The overall expected prevalence of diagnosed HIV in a population similar to those presenting to the BWH ED was 0.71% (95% CI: 0.63%, 0.78%). The prevalence of undiagnosed HIV was estimated at 0.22% (95% CI: 0.10%, 0.42%) and resultant overall prevalence was 0.93%. The proportion of HIV-infection that is undiagnosed in this ED-based setting was estimated to be 23.7% (95% CI: 11.6%, 34.9%) of total HIV-infections.

Conclusions

Despite different methodology, our estimate of the proportion of HIV that is undiagnosed in an ED-setting was similar to previous estimates based on national surveillance data. Universal routine testing programs in EDs should use these data to help plan their yield of HIV detection.

Project description:In hospital settings, depression is an underdetected, undertreated, but prevalent and interfering illness that is associated with significant disability, morbidity, and mortality. A general hospital emergency department (ED) setting may be well suited to identify individuals with clinically significant depressive symptoms, facilitating their referral and treatment.Cross-sectional data of adult ED patients in a general hospital enrolling in a human immunodeficiency virus (HIV) screening study between February 2007 and March 2008 were analyzed. Data included demographic factors, the Center for Epidemiologic Studies Depression Scale (CES-D), alcohol and substance use history, sexual risk taking, and brief medical history. The primary outcome was a dichotomous measure of self-reported clinically significant depressive symptoms. Patients who scored >/= 16 on the CES-D were considered to screen positive for depressive symptoms.Of the 3,262 patients enrolled in the screening trial, 2,588 (79%) completed the survey between February 2007 and March 2008. Among these, 1,945 (75%) completed the psychosocial assessment battery; 596 (31%) survey completers screened positive for clinically significant depressive symptoms. In a multivariable model, female sex (RR = 1.36; 95% CI, 1.16-1.57), being unemployed (RR = 1.61; 95% CI, 1.32-1.93), and lower annual income (RR from 1.73 to 2.24) were associated with increased rates of clinically significant depressive symptoms (CES-D score >/= 16). Clinically significant depressive symptoms were more often present in patients who screened positive for alcohol dependence (RR = 1.48; 95% CI, 1.19-1.78), individuals reporting current smoking (RR = 1.39; 95% CI, 1.17-1.62), those with a prior psychiatric disorder diagnosis (RR = 2.20; 95% CI, 1.80-2.57) or history of hypertension (RR = 1.47; 95% CI, 1.18-1.79), and those who reported ever having sex with an HIV-infected partner (RR = 1.58; 95% CI, 1.08-2.09).This study identified a high frequency of undiagnosed clinically significant depressive symptoms among ED patients and highlights several new demographic and clinical correlates of such symptoms. Screening for and diagnosis of clinical depression in the ED setting introduces important opportunities for acute care providers and for the health care system as a whole.

Project description:BackgroundAtrial fibrillation (AF) prevalence estimates vary and have been based on cohorts with clinically established or diagnosed disease. Undiagnosed AF prevalence estimates are less certain as they are based on nongeneralizable convenience samples.HypothesisBecause AF is often asymptomatic, it my remain undiagnosed until the development of complications such as stroke or heart failure. Consequently, the observed prevalence of diagnosed AF from the literature may underestimate total disease burden. We therefore sought to estimate the total prevalence of both diagnosed and undiagnosed AF.MethodsWe performed a retrospective cohort study from 2012 to 2017 using data from five US medical claims data sets. Undiagnosed AF prevalence was estimated based on the observed incidence of ischemic stroke, systemic embolism (SE), and AF incidence after a stroke/SE. The diagnosed AF cohort included AF patients between Q1 2014 and Q3 2015. The undiagnosed AF cohort were patients with assumed undiagnosed AF in the year before a stroke/SE and who were newly diagnosed with AF in the 3-month poststroke/SE. Stroke/SE incidence was calculated among all AF patients and the ratio of number of undiagnosed AF patients to stroke rate was created. Age- and sex-adjusted estimates were stratified by period of assumed undiagnosed AF before poststroke/SE AF diagnosis (1 or 2 years).ResultsThe estimated US prevalence of AF (diagnosed and undiagnosed) in Q3 2015 was 5 628 000 cases, of which 591 000 cases (11%) were undiagnosed. The assumed 2-year undiagnosed AF prevalence was 23% (1 531 000) of the total prevalent patients with AF (6 568 000). Undiagnosed (vs. diagnosed) AF patients were older and had higher CHA2DS2-VASc scores. Of undiagnosed AF, 93% had CHA2DS2-VASc ≥2 and met OAC criteria.ConclusionsThese contemporary estimates demonstrate the high prevalence of undiagnosed AF in the United States. Undiagnosed AF patients are composed of primarily elderly individuals who if diagnosed, would meet criteria for stroke prevention therapy.
