Risk-based HIV testing in South Carolina health care settings failed to identify the majority of infected individuals

Sub-optimal routine HIV testing rates in an urban HIV and infectious disease clinic

Background: Routine opt-out HIV testing is central to ending the HIV epidemic, as early case finding improves outcomes and reduces transmission. Despite strong evidence-based guideline recommendations, adoption of routine opt-out testing has been sub-optimal. Methods: A survey of providers and staff at an urban HIV and infectious disease clinic assessed awareness and knowledge of guidelines, screening practices, testing barriers, and possible interventions to improve testing. Responses were compared against actual testing data. Results: 86% of survey responders reported familiarity with guideline recommendations, and 37% reported routinely offering opt-out testing to all patients. A review of presumed HIV-negative patients over a two-year period showed that 7% of eligible patients had HIV screening ordered. Despite reported awareness of recommended routine HIV testing, testing was associated with perceived risk rather than offered uniformly, and potentially hampered by the COVID-19 pandemic and utilization of telemedicine visits. Provider education and electronic reminders, patient education, and rapid HIV test availability were proposed interventions to improve screening rates. Conclusions: Routine HIV testing was underutilized, with tests ordered based on perceived acquisition risk rather than offered uniformly.

Healthcare utilization among persons living with HIV in Manitoba, Canada, prior to HIV diagnosis: A case-control analysis

BACKGROUND

Understanding care patterns of persons living with HIV prior to diagnosis can inform prevention opportunities, earlier diagnosis, and engagement strategies. We examined healthcare utilization among HIV-positive individuals and compared them to HIV-negative controls.

METHODS

Data were from a retrospective cohort from Manitoba, Canada. Participants included individuals living with HIV presenting to care between 2007 and 2011, and HIV-negative controls, matched (1:5) by age, sex, and region. Data from population-based administrative databases included physician visits, hospitalizations, drug dispensation, and chlamydia and gonorrhea testing. Diagnoses associated with physician visits were classified according to International Classification of Diseases chapters. Conditional logistic regression models were used to compare cases/controls, with adjusted odds ratios (AORs) and their 95% confidence intervals (95% CI) reported.

RESULTS

A total of 193 cases and 965 controls were included. Physician visits and hospitalizations were higher for cases, compared to controls. In the 2 years prior to case date, cases were more likely to be diagnosed with "blood disorders" (AOR: 4.2, 95% CI: 2.0-9.0), be treated for mood disorders (AOR: 2.4, 95% CI: 1.6-3.4), and to have 1+ visits to a hospital (AOR: 2.2, 95% CI: 1.4-3.6).

CONCLUSION

Opportunities exist for prevention, screening, and earlier diagnosis. There is a need for better integration of healthcare services with public health.

Predictors of late presentation and advanced HIV disease among people living with HIV in Oman (2000-2019)

Background

The aim of this study was to determine the proportions and predictors of late presentation (LP) and advanced HIV disease (AD) in Oman. LP and AD were defined as presenting with a baseline CD4 count of < 350 and < 200 cells/mm3, respectively.

Methods

We conducted a retrospective database analysis of the National HIV Surveillance System to identify Omani people (≥ 13 years old) who were diagnosed with HIV in the period between January 2000 and December 2019 and had a documented baseline CD4 cell count. We calculated the rates and trend over time of LP and AD. A logistic regression was carried out to determine the predictors of LP and AD.

Results

A total of 1418 patients, who were diagnosed with HIV in the period from January 2000 to December 2019, were included; 71% were male and 66% were heterosexuals. The median (IQR) age at diagnosis was 33 (25–39) years. Overall, 71% (95% CI: 68–73) and 46% (95% CI: 44–49) of patients had LP and AD at presentation, respectively. The LP percentage decreased from 76% in 2000–2004 to 69% in 2015–2019; AD percentage decreased from 57 to 46% over the same period. The proportions of men with LP and AD were higher than women (74% vs. 62 and 50% vs. 36%, respectively). The percentages of persons with LP among people aged 13–24, 25–49, and ≥ 50 years were 65, 71, and 84%, respectively. The proportions of persons with AD among people aged 13–24, 25–49, and ≥ 50 years were 39, 46, and 65%, respectively. Logistic regression showed that male sex, older age, having an “unknown” HIV risk factor, and living outside Muscat were independent predictors of AD. Male sex also independently predicted LP.

Conclusions

This analysis indicates that a significant proportion of new HIV cases in Oman continue to present late. This study identified patient subgroups at greatest risk of late HIV diagnosis such as men and older people. Targeted interventions and greater efforts to scale up HIV testing services in Oman are needed.

Economic impact on direct healthcare costs of missing opportunities for diagnosing HIV within healthcare settings

BACKGROUND

The economic consequences of a missed opportunity for HIV testing at an earlier stage of infection within a healthcare setting are poorly described.

METHODS

For all newly diagnosed HIV patients followed at the Southern Alberta HIV/AIDS Clinic (SAC), Calgary, Canada, between 1 April 2011 and 1 April 2016, all clinical encounters occurring < 3 years prior to diagnosis within the region were obtained. The direct costs of HIV care after diagnosis to 31 March 2019 were determined from a payers' perspective and reported as mean cost per patient per month (PPPM) in 2019 Canadian dollars (CDN$). Patients with no encounters for 3 years prior to diagnosis were compared with patients with encounters, with special attention to patients with HIV clinical indicator conditions (HCICs).

RESULTS

Of 388 patients, 60% had one or more prior encounter without HIV testing; 14% had been treated for an HCIC. Females, older patients and heterosexuals were more likely to have prior encounters. At diagnosis, patients with previous encounters presented with lower CD4 counts and higher rates of AIDS. The mean PPPM costs for patients with any prior encounter or for an HCIC-based encounter were 16% and 33% higher, respectively, than for patients with no prior encounters. While mean PPPM costs for antiretroviral drugs and outpatient visits were slightly higher, in-patient costs were 10 times higher for people with HIV who had a previous HCIC encounter vs. those with no encounters (CDN$316 vs. $31, respectively).

CONCLUSIONS

Any healthcare visit, especially for an HCIC, represents relatively easy opportunities for HIV testing. Not testing can result in poorer health and higher costs. Targeted clinical testing and novel interventions to correct overlooked testing opportunities within healthcare settings may be an easy way to implement cost savings.

Missed opportunities within healthcare for an earlier diagnosis of HIV

Despite guidelines, many individuals are not routinely tested for HIV within healthcare settings. Our objective was to quantify and characterize preceding clinical encounters by newly-diagnosed persons living with HIV in southern Alberta, Canada. We discuss the clinical impact of missed HIV testing, and options for remediation. Clinical encounters prior to HIV diagnosis including the discharge diagnosis were collected between 1 April 2011 and 1 April 2016. We followed the HIV Indicator Diseases across Europe Study criteria to identify HIV Clinical Indicator Conditions (HCICs) present at clinical encounters. Patients accessing prior care were compared to those who had not previously accessed care. Of 393 individuals, 231 (58.7%) had ≥1 encounter prior to diagnosis; 224 (57%) of encounters occurred in outpatient clinics, 130 (33.1%) in emergency departments, and 39 (9.9%) in urgent care clinics. Approximately 25% (n = 57) of patients who engaged healthcare had ≥ 1 recognized HCIC but did not receive HIV testing. The most frequent HCICs were infection (n = 34; 60%) and hematological disorders (n = 12; 21%). The median CD4 cell count at HIV diagnosis for patients with an HCIC was 127 cells/mm³. In this population, three of five patients had accessed healthcare prior to diagnosis with one of four presenting with HCICs but were not offered HIV testing. Protocols beyond the current recommendations are urgently required to address missed HIV diagnostic opportunities who engaged healthcare.

Patterns of HIV testing among women diagnosed with invasive cervical cancer in the New Jersey Medicaid Program

PURPOSE

Practice-based guidelines recommend HIV testing during initial invasive cervical cancer (ICC) workup. Determinants of HIV testing during diagnosis of AIDS-defining cancers in vulnerable populations, where risk for HIV infection is higher, are under-explored.

METHODS

We examine factors associated with patterns of HIV testing among Medicaid enrollees diagnosed with ICC. Using linked data from the New Jersey State Cancer Registry and New Jersey Medicaid claims and enrollment files, we evaluated HIV testing among 242 ICC cases diagnosed from 2012 to 2014 in ages 21-64 at (a) any point during Medicaid enrollment (2011-2014) and (b) during cancer workup 6 months pre ICC diagnosis to 6 months post ICC diagnosis. Logistic regression models identified factors associated with HIV testing.

RESULTS

Overall, 13% of women had a claim for HIV testing during ICC workup. Two-thirds (68%) of women did not have a claim for HIV testing (non-receipt of HIV testing) while enrolled in Medicaid. Hispanic/NH-API/Other women had lower odds of non-receipt of HIV testing compared with NH-Whites (OR: 0.40; 95% CI: 0.17-0.94). Higher odds of non-receipt of HIV testing were observed among cases with no STI testing (OR: 4.92; 95% CI 2.27-10.67) and < 1 year of Medicaid enrollment (OR: 3.07; 95% CI 1.14- 8.26) after adjusting for other factors.

CONCLUSIONS

Few women had HIV testing claims during ICC workup. Opportunities for optimal ICC care are informed by knowledge of HIV status. Further research should explore if lack of HIV testing claims during ICC workup is an accurate indicator of ICC care, and if so, to assess testing barriers during workup.

Missed Opportunities to Prescribe Preexposure Prophylaxis in South Carolina, 2013-2016

Background

Expanding use of preexposure prophylaxis (PrEP) in ways that address current racial/ethnic disparities is an important human immunodeficiency virus (HIV) prevention goal. We investigated missed opportunities to provide PrEP during healthcare visits that occur prior to HIV infection.

Methods

This retrospective cohort study linked South Carolina HIV case surveillance data to 3 statewide healthcare databases. Characteristics of patients, healthcare visits and providers, sexually transmitted diseases (STDs), and other diagnoses were assessed for medical encounters occurring before an initial HIV diagnosis. Adjusted odds ratios were used to identify correlates of missed opportunities for PrEP provision.

Results

Of 885 persons newly diagnosed during the study period, 586 (66%) had 4029 visits to a healthcare facility prior to their HIV diagnosis (mean of 6.9 visits) with missed opportunities for provision of PrEP. Emergency medicine-trained clinicians conducted (61%) and primary care clinicians (family practice or internal medicine) conducted 10% of visits. Also, 42% of visits were by persons who were uninsured or self-paid, 36% had public insurance, and 18% had commercial insurance. In multivariable analyses, being female, black, or aged <30 years were statistically significant predictors of having prior healthcare visits. Among persons with at least 1 healthcare visit prior to their HIV diagnosis, 28.5% had a diagnosis of gonorrhea, syphilis, or chlamydia at any visit.

Conclusions

Healthcare visits occurring among persons who would benefit from provision of PrEP, especially persons with diagnosed STDs, should be leveraged to increase use of PrEP and reduce the risk of HIV acquisition.

HIV Testing, Access to HIV-Related Services, and Late-Stage HIV Diagnoses Across US States, 2013-2016

Objectives. To examine state-level factors associated with late-stage HIV diagnoses in the United States.Methods. We examined state-level factors associated with late-stage diagnoses by estimating negative binomial regression models. We used 2013 to 2016 data from the National HIV Surveillance System (late-stage diagnoses), the Behavioral Risk Factor Surveillance System (HIV testing), and the American Community Survey (sociodemographics).Results. Among individuals 25 to 44 years old, a 5% increase in the percentage of the state population tested for HIV in the preceding 12 months was associated with a 3% decrease in late-stage diagnoses. Among both individuals 25 to 44 years of age and those aged 45 years and older, a 5% increase in the percentage of the population living in a rural area was associated with a 2% to 3% increase in late-stage diagnoses.Conclusions. Increasing HIV testing may lower late-stage HIV diagnoses among younger individuals. Increasing HIV-related services may benefit both younger and older people in rural areas.

Timeliness of diagnosis of HIV in Newfoundland and Labrador, Canada: A mixed-methods study

BACKGROUND

Late diagnosis of HIV is associated with poor outcomes and increased cost. Novel HIV testing promotion strategies may reduce late diagnosis. The purpose of this study was to determine the timeliness of HIV testing in Newfoundland and Labrador (NL), missed opportunities for testing, and barriers to HIV testing.

METHODS

Demographic and clinical information from individuals diagnosed with HIV in NL from 2006-2016 was retrospectively reviewed. Patients were also invited to participate in semi-structured interviews regarding knowledge about HIV transmission, risk associated with their behaviour, testing decision making, and testing opportunities.

RESULTS

Fifty-eight new HIV diagnoses occurred during the study period: 53/58 (91.4%) were male and 33/58 (56.9%) were men who have sex with men. The mean age at diagnosis was 40.6 (SD 11.05) years. CD4 count at diagnosis ranged from 2 to 1,408 cells/mm³, with a mean of 387 cells/mm³. For 39/58 (67.2%) of individuals, the first-ever HIV test was positive. Of the 58 patients, 55 (94.8%) had had health care contact within the 5 years prior to diagnosis (mean 13.7 contacts). Heterosexual men were more likely to present with a late diagnosis (p = 0.049). Ten (17.2%) individuals agreed to an interview. Thematic analysis revealed that barriers to testing were stigma, negative health care interactions, denial, and fear of the diagnosis.

CONCLUSIONS

HIV diagnosis is made later in NL than in other Canadian provinces. Late diagnosis may be prevented if HIV testing became a routine testing procedure.

Indicators of self-reported human immunodeficiency virus risk and differences in willingness to get tested by age and ethnicity: An observational study

There are many barriers that prevent people from receiving human immunodeficiency virus (HIV) testing; however, little is known about the impact of age and ethnicity on HIV testing. We explored differences in self-reported HIV risk and willingness to be tested in the 2014 Get Tested Coachella Valley Community Survey by age and ethnicity.Data were collected from 995 participants via survey methods (online, hard copy, and in person). Surveys asked about demographics, sexual history, HIV testing history, thoughts on who should get tested, and future preferences for HIV testing.Most participants were women (62.5%), Hispanic (55.8%), and older than 50 years (51%). Participants who did not receive testing said they did not do so because they did not perceive themselves as at risk of contracting HIV (51.8%). Many participants (24.1%) said they did not receive testing because their health care provider never offered them the HIV test. Participants were more likely to have been tested if they were between 25 and 49 years old, compared to participants aged 50 or older (70.2% vs 48.6%, respectively, P < .001). Participants who were not Hispanic or Latino were more likely to have had an HIV test compared to Hispanic or Latino participants (62.5% vs 51.1%, P < .001).Interventions are needed to reach older adults to address HIV testing and beliefs. These interventions must debunk beliefs among physicians that older adults are not sexually active and beliefs among older adults that only certain populations are at risk of HIV.

Hospital-based routine HIV testing in high-income countries: a systematic literature review

OBJECTIVES

To produce a summary of the published evidence of the barriers and facilitators for hospital-based routine HIV testing in high-income countries.

METHODS

Electronic databases were searched for studies, which described the offer of HIV testing to adults attending emergency departments (EDs) and acute medical units (AMUs) in the UK and US, published between 2006 and 2015. Other high-income countries were not included, as their guidelines do not recommend routine testing for HIV. The main outcomes of interest were HIV testing uptake, HIV testing coverage, factors facilitating HIV screening and barriers to HIV testing. Fourteen studies met the pre-defined inclusion criteria and critically appraised using mixed methods appraisal tool (MMAT).

RESULTS

HIV testing coverage ranged from 9.7% to 38.3% and 18.7% to 26% while uptake levels were high (70.1-84% and 53-75.4%) in the UK and US, respectively. Operational barriers such as lack of time, the need for training and concerns about giving results and follow-up of HIV positive results, were reported. Patient-specific factors including female sex, old age and low risk perception correlated with refusal of HIV testing. Factors that facilitated the offer of HIV testing were venous sampling (vs. point-of-care tests), commitment of medical staff to HIV testing policy and support from local HIV specialist providers.

CONCLUSIONS

There are several barriers to routine HIV testing in EDs and AMUs. Many of these stem from staff fears about offering HIV testing due to the perceived lack of knowledge about HIV. Our systematic review highlights areas which can be targeted to increase coverage of routine HIV testing.

The South Carolina rural-urban HIV continuum of care

The HIV continuum of care model is widely used by various agencies to describe the HIV epidemic in stages from diagnosis through to virologic suppression. It identifies the various points at which persons living with HIV (PLWHIV) within a population fail to reach their next step in HIV care. The rural population in the Southern United States is disproportionally affected by the HIV epidemic. The purpose of this study was to examine these rural-urban disparities using the HIV care continuum model and determine at what stages these differences become apparent. PLWHIV aged 13 years and older in South Carolina (SC) were identified using data from the enhanced HIV/AIDS Reporting System. The percentages of PLWHIV linked to care, retained in care, and virologically suppressed were determined. Rural versus urban residence was determined using the Office of Management and Budget classification. There were 14,523 PLWHIV in SC at the end of 2012; 11,193 (77%) of whom were categorized as urban and 3305 (22%) as rural. There was no difference between urban and rural for those who had received any care: 64% versus 64% (p = .61); retention in care 53% versus 53% (p = .71); and virologic suppression 49% versus 48% (p = .35), respectively. The SC rural-urban HIV cascade represents the first published cascade of care model using rural versus urban residence. Although significant health care disparities exist between rural and urban residents, there were no major differences between rural and urban residents at the various stages of engagement in HIV care using the HIV continuum of care model.

Clinical indicators associated with HIV acquisition in the United States Air Force

Mandatory HIV screening of United States Air Force (USAF) personnel every two years effectively identifies incident cases, however testing frequency limits the ability to detect early HIV infection. Identifying clinical indicators of HIV in the USAF population is necessary to develop a supplemental provider-based targeted testing strategy. We conducted a matched case-control study of male active duty USAF personnel with a new HIV diagnosis (n = 452) between 1996 and 2011 matched to five randomly selected controls (n = 2176). The relationship between clinical diagnoses, determined by ICD-9 codes, and HIV infection was assessed using conditional logistic regression. In unadjusted analyses of ICD-9 codes ever and within the last two years before HIV diagnosis, the conditional odds of HIV infection were greater in those with clinical signs and symptoms of HIV (cOR 5.05, 95% CI 4.00-6.39), mental health diagnoses (cOR 2.61, 95% CI 1.86-3.67), and STI diagnoses (cOR 2.33, 95% CI 1.50-3.60). Compared to those with ≤10 medical encounters in the two years prior to HIV diagnosis, individuals with 11-35 medical encounters (cOR 2.19, 95% CI 1.73-2.79) and >35 medical encounters (cOR 4.15, 95% CI 2.69-6.39) had a higher odds of HIV acquisition. In multivariate analyses, clinical signs and symptoms of HIV within the last two years of HIV diagnosis (cOR 4.10, 95% CI 3.22-5.22) and ever having a mental health diagnosis (cOR 1.97, 95% CI 1.44-2.70) remained significant (p < .01). Clinical encounters, particularly those featuring clinical signs and symptoms of HIV or a history of mental health complaints, provide an opportunity for targeted testing as a supplement to mandated testing at two-year intervals. Provider education to increase HIV testing in persons at risk would enhance early HIV diagnosis and potentially reduce forward transmission in the USAF population.

Late Presentation of HIV Infection: Prevalence, Trends, and the Role of HIV Testing Strategies in Guangzhou, China, 2008-2013

Background. The prevalence, trends, and the role of different HIV testing strategies in late presentation of HIV infection in China were unknown. Methods. Data of newly reported HIV cases in Guangzhou between 2008 and 2013 was analyzed to examine the prevalence, trends, and characteristics of late presentation of HIV infection by three types of HIV testing strategies. Results. Overall, 53.2% (1412/2653) and 27.3% (724/2653) met the criteria of late presentation and presentation with advanced HIV disease. The overall trend of late presentation of HIV infection within the study period was declining. Late presentation was 62.9% in 2008 and dropped to 43.3% in 2013 (P < 0.001); presentation with advanced HIV disease was 40.3% in 2008 and dropped to 15.2% in 2013 (P < 0.001). Of the three testing strategies, PITC presented higher odds of both late presentation [AOR (95% CI): PITC versus VCT: 1.37 (1.09, 1.73); PITC versus MHT: 3.09 (2.16, 4.42)] and presentation with advanced HIV disease [AOR (95% CI): PITC versus VCT: 1.65 (1.29, 2.11); PITC versus MHT: 13.14 (8.47, 20.39)]. Conclusions. Although the late presentation of HIV infection was declining, it was still high in Guangzhou. The worse situation among PITC cases urges the policy adjustment in medical settings to increase early HIV diagnosis.

Missed Opportunities for HIV Diagnosis

It has been previously shown that patients may present for multiple health issues in the years preceding their initial HIV diagnosis. This retrospective cohort study analyzed the data of patients with a new HIV diagnosis, at Ochsner Health System between January 1, 2011, and December 31, 2012. The primary end point was missed opportunities, the number of healthcare visits these patients made in the 2 years prior to being diagnosed with HIV. The 125 patients in the study cohort had 649 healthcare visits during which an HIV test was not performed. These missed opportunities are the key to capturing the undiagnosed and unaware HIV-positive individual. Primary care is an ideal setting to conduct HIV testing for those who have access to regular health care. However, nontraditional providers should also be encouraged to conduct HIV testing regardless of their ability to provide treatment because evidence shows that knowledge of the diagnosis may change behavior.

HIV community viral load trends in South Carolina

Community viral load is an aggregate measure of HIV viral load in a particular geographic location, community, or subgroup. Community viral load provides a measure of disease burden in a community and community transmission risk. This study aims to examine community viral load trend in South Carolina and identify differences in community viral load trends between selected population subgroups using a state-wide surveillance dataset that maintains electronic records of all HIV viral load measurements reported to the state health department. Community viral load trends were examined using random mixed effects models, adjusting for age, race, gender, residence, CD4 counts, HIV risk group, and initial antiretroviral regimen during the study period, and time. The community viral load gradually decreased from 2004 to 2013 ( p < 0.0001). The number of new infections also decreased ( p = 0.0001) over time. A faster rate of decrease was seen among men compared to women ( p < 0.0001), men who have sex with men ( p = 0.0001) compared to heterosexuals, patients diagnosed in urban areas compared to that in rural areas ( p = 0.0004), and patients prescribed single-tablet regimen compared to multiple-tablet regimen ( p < 0.0001). While the state-wide community viral load decreased over time, the decline was not uniform among residence at diagnosis, HIV risk group, and single-tablet regimen versus multiple-tablet regimen subgroups. Slower declines in community viral load among females, those in rural areas, and heterosexuals suggest possible disparities in care that require further exploration. The association between using single-tablet regimen and faster community viral load decline is noteworthy.

Prior history of testing for syphilis, hepatitis B and hepatitis C among a population-based cohort of HIV-positive individuals and their HIV-negative controls

Understanding patterns of serological testing for hepatitis B & C, and syphilis among HIV-positive individuals, prior to HIV diagnosis, can inform HIV diagnosis, engagement and prevention strategies. This was a population-based, retrospective analysis of prior serological testing among HIV-positive individuals in Manitoba, Canada. HIV cases were age-, sex- and region-matched to HIV-negative controls at a 1:5 ratio. Conditional logistic regression was used to examine previous serological tests and HIV status. Odds ratios (ORs) and their 95% confidence intervals (95% CI) were reported. A total of 193 cases and 965 controls were included. In the 5 years prior to diagnosis, 50% of cases had at least one test, compared to 26% of controls. Compared to those who did not have serological testing in the 5 years prior to HIV infection, those who had one serological test were at twice the odds of being HIV positive (OR: 1.9, 95% CI: 1.2-2.9), while those with 2 or more tests were at even higher odds (OR: 5.5, 95%CI: 3.7-8.4). HIV cases had higher serological testing rates. Interactions between public health and other healthcare providers should be strengthened.

Recent HIV Testing Prevalence, Determinants, and Disparities Among U.S. Older Adult Respondents to the Behavioral Risk Factor Surveillance System

BACKGROUND

Although routine human immune deficiency virus (HIV) testing during health care visits is recommended for most adults, many older adults (i.e., ages 50-64 years) do not receive it. This study identified factors associated with HIV testing in the past 12 months (i.e., recent HIV testing) among US adults in the 3 categories of older adulthood (50-54, 55-59, and 60-64 years) for which routine HIV testing is recommended.

METHOD

This was a cross-sectional analysis of data from US older adult respondents to the 2010 Behavioral Risk Factor Surveillance System. We calculated prevalence (proportions) of HIV testing by age category and race/ethnicity. Using multiple logistic regression, we identified predisposing, enabling, and need factors associated with recent HIV testing within and across age categories, by race/ethnicity and controlling for covariates.

RESULTS

HIV testing prevalence was low (<5%), varied by race/ethnicity, and decreased with age. Within and across age categories, the odds of testing were highest among blacks (odds ratio [OR], 3.47; 95% confidence interval [CI], 2.82-4.25) and higher among Latinos (OR, 2.06; 95% CI, 1.50-2.84) and the oldest and youngest categories of American Indians/Alaska Natives (OR, 2.48; 95% CI, 1.11-5.55; OR, 2.98; 95% CI, 1.49-5.95) than among whites. Those reporting a recent doctor visit (OR, 2.32; 95% CI, 1.92-2.74) or HIV risk behaviors (OR, 3.50; 95% CI, 2.67-4.59) had higher odds of HIV testing.

CONCLUSION

Regardless of risk, the oldest older adults, whites, and older women may forego HIV testing. Doctor visits may facilitate HIV testing. Additional research is needed to understand why eligible older adults seen by providers may not be screened for HIV infection.

Perspectives on menopause and women with HIV

Since the implementation of effective combination antiretroviral therapy, HIV infection has been transformed from a life-threatening condition into a chronic disease. As people with HIV are living longer, aging and its associated manifestations have become key priorities as part of HIV care. For women with HIV, menopause is an important part of aging to consider. Women currently represent more than one half of HIV-positive individuals worldwide. Given the vast proportion of women living with HIV who are, and will be, transitioning through age-related life events, the interaction between HIV infection and menopause must be addressed by clinicians and researchers. Menopause is a major clinical event that is universally experienced by women, but affects each individual woman uniquely. This transitional time in women's lives has various clinical implications including physical and psychological symptoms, and accelerated development and progression of other age-related comorbidities, particularly cardiovascular disease, neurocognitive dysfunction, and bone mineral disease; all of which are potentially heightened by HIV or its treatment. Furthermore, within the context of HIV, there are the additional considerations of HIV acquisition and transmission risk, progression of infection, changes in antiretroviral pharmacokinetics, response, and toxicities. These menopausal manifestations and complications must be managed concurrently with HIV, while keeping in mind the potential influence of menopause on the prognosis of HIV infection itself. This results in additional complexity for clinicians caring for women living with HIV, and highlights the shifting paradigm in HIV care that must accompany this aging and evolving population.

Comparing Cost-Effectiveness of HIV Testing Strategies: Targeted and Routine Testing in Washington, DC

Background

Routine HIV testing is an essential approach to identifying undiagnosed infections, linking people to care and treatment, and preventing new infections. In Washington, DC, where HIV prevalence is 2.4%, a combination of routine and targeted testing approaches has been implemented since 2006.

Methods

We sought to evaluate the cost effectiveness of the District of Columbia (DC) Department of Health’s routine and targeted HIV testing implementation strategies. We collected HIV testing data from 3 types of DC Department of Health-funded testing sites (clinics, hospitals, and community-based organizations); collected testing and labor costs; and calculated effectiveness measures including cost per new diagnosis and cost per averted transmission.

Results

Compared to routine testing, targeted testing resulted in higher positivity rates (1.33% vs. 0.44%). Routine testing averted 34.30 transmissions per year compared to targeted testing at 17.78. The cost per new diagnosis was lower for targeted testing ($2,467 vs. $7,753 per new diagnosis) as was the cost per transmission averted ($33,160 vs. $104,205). When stratified by testing site, both testing approaches were most cost effective in averting new transmissions when conducted by community based organizations ($25,037 routine; $33,123 targeted) compared to hospitals or clinics.

Conclusions

While routine testing identified more newly diagnosed infections and averted more infections than targeted testing, targeted testing is more cost effective per diagnosis and per transmission averted overall. Given the high HIV prevalence in DC, the DC Department of Health’s implementation strategy should continue to encourage routine testing implementation with emphasis on a combined testing strategy among community-based organizations.

Trends in HIV Testing Among U.S. Older Adults Prior to and Since Release of CDC's Routine HIV Testing Recommendations: National Findings from the BRFSS

OBJECTIVE

This study examined temporal trends in HIV testing among U.S. older adults (50-64 years of age) before and after the release of CDC's routine HIV testing recommendations in 2006.

METHODS

The sample (n=872,797; 51.4% female) comprised 2003-2010 Behavioral Risk Factor Surveillance System respondents in the oldest categories to which the recommendations apply: 50-54 years (34.5%, n=301,519), 55-59 years (34.1%, n=297,865), and 60-64 years (31.3%, n=273,413). We calculated (1) four-year pooled prevalences of past-year HIV testing before and after 2006, when the recommendations were released; and (2) annual prevalences of HIV testing overall and by age category from 2003-2010. Using weighted, multivariable logistic regression analyses, we examined binary (pre- vs. post-recommendations) and annual changes in testing, controlling for covariates. We stratified the data by recent doctor visits, examined racial/ethnic differences, and tested for linear and quadratic temporal trends.

RESULTS

Overall and within age categories, the pooled prevalence of past-year HIV testing decreased following release of the recommendations (p<0.001). The annual prevalence decreased monotonically from 2003 (5.5%) to 2006 (3.6%) (b=-0.16, p<0.001) and then increased immediately after release of the recommendations, but decreased to 3.7% after 2009 (b=0.01, p<0.001). By race/ethnicity, testing increased over time among non-Hispanic black people only. Annual prevalence also increased among respondents with recent doctor visits.

CONCLUSION

CDC's HIV testing recommendations were associated with a reversal in the downward trend in past-year HIV testing among older adults; however, the gains were neither universal nor sustained over time.

HIV testing rate increased following recommendation of routine screening of acute medical admissions at Royal Darwin Hospital

Background To improve HIV detection, Royal Darwin Hospital implemented a guideline in 2012 recommending routine HIV testing for all adult acute medical admissions. This study aimed to determine the uptake, point prevalence and impact on late diagnosis of HIV screening following guideline implementation.

METHODS

Data on the number of HIV tests and number of acute medical admissions over the 8 months prior and post guideline implementation were extracted from hospital databases. A qualitative survey was conducted to ascertain clinician response to routine screening.

RESULTS

Fourteen per cent of admissions were tested post-implementation compared with 5.3% during the implementation period (P<0.001). HIV prevalence pre-implementation was 1.4% compared with 0.3% following implementation (P<0.05). The average CD4 count at diagnosis was <200 cells/mm(3).

CONCLUSIONS

There was a significant increase in HIV testing following guideline implementation; however, the overall testing rate remained low. Routine screening did not increase detection of HIV, and HIV continues to be diagnosed late at Royal Darwin Hospital. Methods for improving understanding of the rationale for routine screening and increased promotion of the guidelines are required to increase testing.

"Express testing" in STI clinics: extant literature and preliminary implementation data

In an era of stagnant resources for sexually transmitted infection (STI) and HIV testing clinics, and at a time of ongoing-and in some cases increasing-STI and HIV transmission, it is important to trial and evaluate novel STI/HIV testing strategies. Based on the extant literature, one such approach is express testing, which includes full STI/HIV testing (as per clinical indication and client request), altered pretest counseling, and no physical examination for both men and women. In this paper, we overview the available research about express testing, including the literature on less-invasive testing, the effects of risk reduction counseling HIV testin/HIV testing, available research on various HIV testing modalities, and the reasons people undergo such testing. Thereafter, we overview our express testing program, which includes a detailed review of our clinical processes (which are unique within the published literature). Lastly, we provide some preliminary pre-implementation data to support the proposed efficacy of express testing.

Prevalence and factors associated with late HIV diagnosis

While highly active antiretroviral therapy has been successful in delaying progression into AIDS, late HIV diagnosis remains a major contributor to the mortality and morbidity of AIDS. An epidemiological study was conducted to evaluate the prevalence and factors of late diagnosis and the characteristics of those individuals with late diagnosis in Liuzhou city. Patients with late diagnosis were defined as either those who were diagnosed with AIDS at the time of HIV diagnosis or as those who developed AIDS no more than 1 year after HIV diagnosis. Of 899 participants, 72.6% had a late diagnosis. Common characteristics of those who experienced late diagnosis included older participants, those who were unexpectedly diagnosed while seeking other medical attention, participants who believed they could not acquire HIV from their regular heterosexual partners, those who never considered getting tested for HIV, and patients with unexplained weight loss, angular cheilitis, or prolonged fever prior to HIV diagnosis. On the other hand, those participants who were diagnosed via testing at compulsory rehabilitation centers and those whose annual household income was greater than 30,000 Yuan were less likely to be diagnosed late. These results suggested that late HIV diagnosis is common in Liuzhou city, and it is essential to promote appropriate strategies to detect HIV infections earlier. Strategies that require HIV/AIDS patients to notify their spouse/sexual-partners about their HIV-positive results within one month and start provider-initiated HIV testing and counseling in medical facilities are beneficial to earlier HIV diagnosis.

Disparities in viral load and CD4 count trends among HIV-infected adults in South Carolina

On a population level, trends in viral load (VL) and CD4 cell counts can provide a marker of infectivity and an indirect measure of retention in care. Thus, observing the trend of CD4/VL over time can provide useful information on disparities in populations across the HIV care continuum when stratified by demography. South Carolina (SC) maintains electronic records of all CD4 cell counts and HIV VL measurements reported to the state health department. We examined temporal trends in individual HIV VLs reported in SC between January 1, 2005 and December 31, 2012 by using mixed effects models adjusting for gender, race/ethnicity, age, baseline CD4 count, HIV risk category, and residence. Overall VL levels gradually decreased over the observation period. There were significant differences in the VL decline by gender, age groups, rural/urban residence, and HIV risk exposure group. There were significant differences in CD4 increases by race/ethnicity, age groups, and HIV risk exposure group. However, the population VL declines were slower among individuals aged 13-19 years compared to older age groups (p<0.0001), among men compared to women (p=0.002), and among people living with HIV/AIDS (PLWHA) with CD4 count ≤200 cell/mm(3) compared to those with higher CD4 counts (p<0.0001). Significant disparities were observed in VL decline by gender, age, and CD4 counts among PLWHA in SC. Population based data such as these can help streamline and better target local resources to facilitate retention in care and adherence to medications among PLWHA.

HIV testing among clients in high HIV prevalence venues: disparities between older and younger adults

The Centers for Disease Control and Prevention recommends routine human immunodeficiency virus (HIV) testing of every client presenting for services in venues where HIV prevalence is high. Because older adults (aged ≥50 years) have particularly poor prognosis if they receive their diagnosis late in the course of HIV disease, any screening provided to younger adults in these venues should also be provided to older adults. We examined aging-related disparities in recent (past 12 months) and ever HIV testing in a probability sample of at-risk adults (N = 1238) seeking services in needle exchange sites, sexually transmitted disease clinics, and Latino community clinics that provide HIV testing. Using multiple logistic regression with generalized estimating equations, we estimated associations between age category (<50 years vs. ≥50 years) and each HIV testing outcome. Even after controlling for covariates such as recent injection drug use, older adults had 40% lower odds than younger adults did of having tested in the past 12 months (odds ratio [OR] = 0.6; 95% confidence interval [CI] = 0.40-0.90) or ever (OR = 0.6; 95% CI = 0.40-0.90). Aging-related disparities in HIV testing exist among clients of these high HIV prevalence venues and may contribute to known aging-related disparities in late diagnosis of HIV infection and poor long-term prognosis.

Racial and ethnic disparities in future testing intentions for HIV: United States, 2007-2010: results from the National Health Interview Survey

This study examined racial/ethnic differences in rationale for intending to test for HIV. Data were analyzed from 98,971 adults from the 2007-2010 National Health Interview Survey. An estimated 38.5 % of respondents previously tested for HIV. Testing as part of a medical checkup or procedure was the most common reason for being tested among studied racial/ethnic groups. Non-Hispanic whites (80.7 %) and non-Hispanic Asians (71.2 %) had higher proportions (p < 0.001) of respondents that have not been tested for HIV due to believing they were unlikely exposed. Non-Hispanic blacks (ARR: 2.55; 95 % CI 2.39-2.72) and Hispanics (ARR: 1.81; 95 % CI 1.68-1.95) who ever tested for HIV were significantly more likely to report positive future testing intentions compared to non-Hispanic whites. Additional efforts to increase the availability of HIV tests by making HIV testing a routine part of medical care and increasing knowledge of HIV transmission, risk-perception, and treatment may reduce racial/ethnic disparities in HIV testing.

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.

The potential impact of routine testing of individuals with HIV indicator diseases in order to prevent late HIV diagnosis

Background

The aim of our work was to evaluate the potential impact of the European policy of testing for HIV all individuals presenting with an indicator disease, to prevent late diagnosis of HIV. We report on a retrospective analysis among individuals diagnosed with HIV to assess whether a history of certain diseases prior to HIV diagnosis was associated with the chance of presenting late for care, and to estimate the proportion of individuals presenting late who could have been diagnosed earlier if tested when the indicator disease was diagnosed.

Methods

We studied a large cohort of individuals newly diagnosed with HIV infection in 13 counselling and testing sites in the Lazio Region, Italy (01/01/2004-30/04/2009). Considered indicator diseases were: viral hepatitis infection (HBV/HCV), sexually transmitted infections, seborrhoeic dermatitis and tuberculosis. Logistic regression analysis was performed to estimate association of occurrence of at least one indicator disease with late HIV diagnosis.

Results

In our analysis, the prevalence of late HIV diagnosis was 51.3% (890/1735). Individuals reporting at least one indicator disease before HIV diagnosis (29% of the study population) had a lower risk of late diagnosis (OR = 0.7; 95%CI: 0.5-0.8) compared to those who did not report a previous indicator disease. 52/890 (5.8%) late presenters were probably already infected at the time the indicator disease was diagnosed, a median of 22.6 months before HIV diagnosis.

Conclusions

Our data suggest that testing for HIV following diagnosis of an indicator disease significantly decreases the probability of late HIV diagnosis. Moreover, for 5.5% of late HIV presenters, diagnosis could have been anticipated if they had been tested when an HIV indicator disease was diagnosed.

However, this strategy for enhancing early HIV diagnosis needs to be complemented by client-centred interventions that aim to increase awareness in people who do not perceive themselves as being at risk for HIV.

"It is not easy": challenges for provider-initiated HIV testing and counseling in Flanders, Belgium

This study identified physicians' HIV testing practices and their barriers toward implementing provider-initiated HIV testing and counseling (PITC) for Sub-Saharan African migrants (SAM) in Flanders, Belgium. In-depth interviews were conducted on a purposive sample of 20 physicians (ten GPs and ten internists). GPs performed mainly patient-initiated tests, while internists carried out tests based on disease indicators and risk behavior. For the most part, World Health Organization (WHO) guidelines were not followed. Study participants were not in favor of implementing PITC. Reasons included lack of information on the HIV epidemic among SAM, fear of stigmatizing patients, perceiving testing as unethical for undocumented patients, questionable relevance of pre-test counseling, lack of expertise in discussing sexuality, language barriers, lack of time, and the absence of a national or regional HIV testing policy. Implementing PITC will require appropriate training of service providers. Also, supporting policies should be developed with the participation of stakeholders encouraging "normalization" of HIV testing.

Epidemiological characteristics of HIV-infected women with and without a history of criminal justice involvement in South Carolina

The circumstances that lead to incarceration may potentiate the HIV/AIDS epidemic and this has become an emerging public health concern. In the United States and in most jurisdictions, HIV prevalence in the correctional setting is higher among female inmates than male inmates. This dichotomy is not fully understood and few studies have focused on women in the South. Using data from the South Carolina (SC) electronic HIV/AID Reporting System, the SC Law Enforcement Criminal History database, and a public access website of the SC Department of Corrections, the authors describe the epidemiological characteristics and correctional history of a population of HIV-infected women in SC diagnosed between January 1, 1996, and December 31, 2005.

Late HIV detection among adult males in Los Angeles County, 2000-2004

We analyzed HIV surveillance data on white, black, and Latino males diagnosed with HIV between 2000 and 2004 in Los Angeles County (LAC) to identify associations between individual- and community-level factors and late HIV detection by race/ethnicity. We defined late HIV detection as an AIDS diagnosis within 6 months of HIV diagnosis. We conducted multilevel analysis to determine individual- and community-level risk factors associated with late HIV detection stratified by race/ethnicity. We mapped HIV-positive males with late HIV detection by race/ethnicity at the zip code level within LAC to determine high burden areas. Overall, 38% of all males met the definition of late HIV detection. By race/ethnicity, 44% of Latinos, 38% of blacks, and 30% of whites were detected late in their course of HIV infection. Latinos and whites had multiple individual-level risk factors associated with late HIV detection. Among black males, only older age at HIV diagnosis was associated with late HIV detection. The only community-level risk factor associated with late HIV detection was among Latinos living in communities with less than 6% of men who have sex with men (proxy for stigma). Mapping the distribution of late HIV detection showed late detection areas generalized across LAC for Latino males in comparison with white and black males whose maps showed clustered areas of late HIV detection. Analysis and mapping of individual- and community-level risk factors associated with late HIV detection provides an important tool for targeting prevention resources to areas and populations with the highest burden of disease.

Linkages to care for newly diagnosed individuals who test HIV positive in nonprimary care settings

Linkage services are an increasingly important component of the continuum of care for people living with HIV, particularly for individuals diagnosed in nonprimary care settings who are less likely than those identified in primary care settings to have a usual source of care. This study examines successful models used by hospital emergency departments, health department outpatient clinics, and other nonprimary care providers for testing, linking, and engaging newly diagnosed HIV-positive racial and ethnic minorities into medical care. Based on studies of five mature linkage-to-care (LTC) programs implemented in geographically and institutionally diverse settings, we identify five key characteristics that make them viable. Effective linkage programs are low cost, intensive, time limited, unique, and flexible. We also identify four core components of successful LTC protocols: directly employed linkage workers, active referral to medical care, person-centered linkage case management, and cultural and linguistic concordance. Finally, we develop a set of operational strategies to help providers address barriers at all levels of the health care system to help promote the effective linkage of newly diagnosed patients to care. We organize the strategies around four key areas: adherence to LTC protocols, selection of linkage workers, execution of linkage programs, and sustainability of linkage programs. The findings presented in this study provide a practical and operational guide for developing and implementing policies and procedures for linking newly diagnosed individuals who test HIV positive in nonprimary care settings into ongoing care for HIV infection.

Comparing Measures of Late HIV Diagnosis in Washington State

As more US HIV surveillance programs routinely use late HIV diagnosis to monitor and characterize HIV testing patterns, there is an increasing need to standardize how late HIV diagnosis is measured. In this study, we compared two measures of late HIV diagnosis, one based on time between HIV and AIDS, the other based on initial CD4⁺ results. Using data from Washington's HIV/AIDS Reporting System, we used multivariate logistic regression to identify predictors of late HIV diagnosis. We also conducted tests for trend to determine whether the proportion of cases diagnosed late has changed over time. Both measures lead us to similar conclusions about late HIV diagnosis, suggesting that being male, older, foreign-born, or heterosexual increase the likelihood of late HIV diagnosis. Our findings reaffirm the validity of a time-based definition of late HIV diagnosis, while at the same time demonstrating the potential value of a lab-based measure.

HIV testing among midlife women in the deep south: an analysis of the 2008 Behavioral Risk Factor Surveillance System survey data

OBJECTIVE AND BACKGROUND

Our objective was to examine HIV testing uptake among postmenopausal women. Many women are routinely tested for HIV during pregnancy. Disproportionate numbers of women beyond reproductive age are diagnosed HIV-positive late in the disease course. Some older women and healthcare providers have dismissed early AIDS symptoms as signs of aging. This has resulted in missed opportunities for early initiation of effective antiretroviral therapy.

METHODS

Behavioral Risk Factor Surveillance System (BRFSS) 2008 data were analyzed for non-Hispanic white and non-Hispanic black women (50-64 years) from six deep south states. Logistic regression models examined associations between uptake of HIV testing and population/behavioral characteristics.

RESULTS

More than half of our sample (1091 of 2027) had an HIV test during their postreproductive years (>45 years old). Women 50-54 years old were about 40% as likely to have been tested for HIV during their postreproductive years as those 60-64 years old (adjusted odds ratio [AOR] 0.62, 95% confidence interval [CI] 0.45-0.84). Population characteristics, such as race/ethnicity, family poverty status, and urbanization, as well as HIV exposure risk, were all potential confounders of this relationship.

CONCLUSIONS

Routine HIV testing is underused among women during their postreproductive years. HIV prevention messages that target midlife women are needed to reduce the prevalence of HIV/AIDS and disproportionate burden of late diagnosed HIV infection in this population.

HIV testing in women: missed opportunities

OBJECTIVE

To investigate opportunities for early human immunodeficiency virus (HIV) testing of women.

METHODS

A retrospective cohort study design linked case reports from HIV surveillance to several statewide health-care databases. Medical encounters occurring before the first positive HIV test (missed opportunities) were categorized by diagnosis/procedure codes to distinguish visits that were likely to have prompted an HIV test. Women were categorized as late testers (AIDS diagnosis <12 months from first HIV test date), non-late testers (no AIDS diagnosis during study period or diagnosis of AIDS >12 months of HIV diagnosis), of reproductive age (13-44 years old), and not of reproductive age (>44 years old). Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were used to estimate risk and its statistical significance.

RESULTS

Of 3303 HIV-infected women diagnosed during the study period, 2408 (73%) had missed opportunity visits. Late testers (39%) were more likely to be black than white (aOR 1.48, 95% CI 1.12-1.95), be older (>44 years old; aOR 7.85, 95% CI 4.49-13.7), and have >10 missed opportunity visits (aOR 2.17, 95% CI 1.62-2.91). Fifty-four percent of women >44 years old were also late testers. Women >44 years old had lower median initial CD4 counts (p<0.001). The top two procedures were the same for all groups of women but mammography was ranked fourth for women >44 years old and Papanicolau smear was ranked fourth for late testers.

CONCLUSIONS

Feasibility and acceptability of routine HIV testing in nontraditional health-care settings, such as mammography and Papanicolau screenings, should be explored to identify late testers and older (not of reproductive age) HIV-infected women.

Comparison of missed opportunities for earlier HIV diagnosis in 3 geographically proximate emergency departments

OBJECTIVE

Differences in the prevalence of undiagnosed HIV between different types of emergency departments (EDs) are not well understood. We seek to define missed opportunities for HIV diagnosis within 3 geographically proximate EDs serving different patient populations in a single metropolitan area.

METHODS

For an urban academic, an urban community, and a suburban community ED located within 10 miles of one another, we reviewed visit records for a cohort of patients who received a new diagnosis of HIV between July 1999 and June 2003. Missed opportunities for earlier HIV diagnosis were defined as ED visits in the year before diagnosis, during which there was no documented ED HIV testing offer or test. Outcomes were the number of missed opportunity visits and the number of patients with a missed opportunity for each ED. We secondarily reviewed medical records for missed opportunity encounters, using an extensive list of indications that might conceivably trigger testing.

RESULTS

Among 276 patients with a new HIV diagnosis, 123 (44.5%) visited an ED in the year before diagnosis or received a diagnosis in the ED. The urban academic ED HIV testing program diagnosed 23 (8.3%) cases and offered testing to 24 (8.7%) patients who declined. Missed opportunities occurred during 187 visits made by 76 (27.5%) patients. These included 70 patients with 157 visits at the urban academic ED, 9 patients with 24 visits at the urban community ED, and 4 patients with 6 visits at the suburban community ED. Medical records were available for 172 of the 187 missed opportunity visits. Visits were characterized by the following potential testing indicators: HIV risk factors (58; 34%), related diagnosis indicating risk (7; 4%), AIDS-defining illness (8; 5%), physician suspicion of HIV (29; 17%), and nonspecific signs or symptoms of illness potentially consistent with HIV (126; 73%).

CONCLUSION

Geographically proximate EDs differ in their opportunities for earlier HIV diagnosis, but all 3 sites had missed opportunities. Many ED patients with undiagnosed HIV have potential indications for testing documented even in the absence of a dedicated risk assessment, although most of these are nonspecific signs or symptoms of illness that may not be clinically useful selection criteria.

HIV testing among Deep South residents 50 to 64 years old with cardiovascular disease and/or diabetes

PURPOSE

To describe HIV testing among Deep South residents aged 50 to 64 years old with cardiovascular disease (CVD) and/or diabetes.

METHODS

Deep South residents from Alabama, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina who completed the 2008 Behavioral Risk Factor Surveillance System (BRFSS) survey were sampled. Associations between chronic health conditions (CVD, diabetes) and human immunodeficiency virus (HIV) testing were examined.

RESULTS

Fewer than one-third (30.8%) of the sample (n = 1017) reported that they had been tested for HIV. Of the weighted sample of adults tested for HIV, the mean age--56.63 +/- 0.20 SE (95% confidence interval [CI], 56.24-57.03)--was significantly lower than that of those who had never been tested for HIV--57.60 +/- 0.12 SE (95% CI, 57.37-57.84; p < .0001). Although not statistically significant, HIV testing was slightly higher among men (53.3%) (p = .9432). Persons with CVD or diabetes were 22% less likely to report that they had been tested for HIV, compared to those with both CVD and diabetes (adjusted odds ratio [AOR], 0.776; 95% CI, 0.611-0.985).

CONCLUSIONS

Chronic conditions (CVD, diabetes) among HIV-infected persons can be adversely affected by antiretroviral regimens. All adults 50 to 64 years old should be routinely offered an HIV test if their HIV serostatus is unknown, regardless of perceived risk for HIV/AIDS. Our findings suggest that linking HIV testing with routine checkups for persons with CVD and/or diabetes is a potentially missed opportunity for earlier diagnosis of HIV infection, especially among older adults who are at a greater risk of being diagnosed with AIDS within 1 year of an initial HIV-positive diagnosis.

Late HIV diagnosis in Houston/Harris County, Texas, 2000-2007

This cross-sectional study aimed to evaluate the prevalence and predictive factors associated with late HIV diagnoses in Houston, Texas using surveillance data. Study subjects were Houston/Harris County residents, 13 years or older, diagnosed with HIV and reported to the Houston Department of Health and Human Services. Late HIV diagnosis was defined as an AIDS diagnosis within three months of an HIV diagnosis. Logistic regression was used to investigate the association between late HIV diagnoses and predictive factors. We found 31% of the study population had late HIV diagnoses. The Hispanic population, men, older individuals, heterosexuals, and those diagnosed in private facilities were more likely to receive late HIV diagnoses. Sensitivity analysis was conducted to evaluate the effect of time from HIV to AIDS diagnosis on the prevalence of a late diagnosis, and on the predictors of late diagnosis. The sensitivity analysis showed time affects prevalence, but not the odds ratios of the risk factors for late diagnosis. This finding suggests HIV prevention programs should specifically target these populations at risk for late HIV diagnosis to encourage frequent HIV testing.

Risk behavior disclosure during HIV test counseling

Individualized risk assessments during HIV testing are an integral component of prevention counseling, a currently recommended behavioral intervention for patients in high-risk settings. Additionally, aggregate risk assessment data are the source of aggregate behavioral statistics that inform prevention programs and allocation of resources. Consequently, inaccurate or incomplete risk behavior disclosure during test counseling may impact the efficacy of the counseling intervention, as well as bias aggregate behavioral statistics. To quantify client-reported accuracy during the risk assessment and identify barriers and facilitators to risk behavior disclosure, we interviewed young men accessing HIV testing services in a southeastern United States city using mixed methodology. Data were collected from August 2007 to April 2008. Based on data collected via an audio and computer-assisted self-interview (n = 203), over 30% of men reported that they were not accurate during the risk assessment. Participants reported numerous interpersonal facilitators to complete disclosure. During qualitative interviews (n = 25), participants revealed that many did not understand the purpose of the risk assessment. Findings suggest that risk assessments completed during HIV test counseling may be incomplete. Modifications to the risk assessment process, including better explaining the role of the risk assessment in prevention counseling, may increase the validity of the data.

The treatment of patients with HIV

BACKGROUND

Infection with the human immunodeficiency virus (HIV) remains a major medical challenge.

METHODS

Selective literature review, including the current German/Austrian, European, and American guidelines on the treatment of HIV infection in adults.

RESULTS

In Germany, 3000 persons become infected with HIV each year; in 2009, 67,000 persons in Germany were living with HIV. When highly active antiretroviral therapy (HAART) is initiated in time, patients can achieve a nearly normal life expectancy. Nonetheless, in Germany as elsewhere, 30% of patients receive the diagnosis of HIV infection only when they have reached the AIDS stage of the disease or are suffering from advanced immunodeficiency. HAART should be started, at the latest, when the CD4-positive helper cell count drops below 350/microL. Primary drug resistances, accompanying illnesses, and the patient's living circumstances must all be taken into account in the selection of antiretroviral drugs. The goal of treatment is lasting suppression of HIV-RNA to below 50 copies per milliliter of plasma.

CONCLUSIONS

HIV testing should be offered to all patients at high risk for HIV infection and all persons newly diagnosed with a sexually transmitted disease. As persons with HIV grow older, their treatment is complicated by increasing comorbidity and requires increased vigilance for possible drug interactions.

Feasibility and acceptability of door-to-door rapid HIV testing among latino immigrants and their HIV risk factors in North Carolina

Latino immigrants in the United States are disproportionally impacted by the HIV epidemic but face barriers to clinic-based testing. We assessed a community-based strategy for rapid HIV testing by conducting "door-to-door" outreaches in apartments with predominately Latino immigrants in Durham, North Carolina, that has experienced an exponential growth in its Latino population. Eligible persons were 18 years or older, not pregnant, and reported no HIV test in the previous month. Participants were asked to complete a survey and offered rapid HIV testing. Of the 228 Latino participants, 75.4% consented to HIV testing. There was a high prevalence of sexual risk behaviors among participants, with 42.5% acknowledging ever having sex with a commercial sex worker (CSW). Most (66.5%) had no history of prior HIV testing. In bivariate analysis, perceived HIV risk, no history of HIV testing, sex with a CSW, sex in exchange for drugs or money, living with a partner, and alcohol use were significantly associated with test acceptance. In the multivariate analysis, participants who had never been tested for HIV were more likely to consent to rapid HIV testing than those who had tested in the past (adjusted odds ratio 2.5; 95% confidence interval [CI], 1.1, 5.6). Most participants supported rapid HIV testing in the community (97%). Door-to-door rapid HIV testing is a feasible and acceptable strategy for screening high-risk Latino immigrants in the community. Factors associated with HIV risk among Latino migrants and immigrants in the United States should be considered along with novel testing strategies in HIV prevention programs.

Pap test and HIV testing behaviors of South Carolina women 18-64 years old

BACKGROUND

Pap tests are used to detect abnormal cell growth in the cervix. Early detection of precancerous cells increases the likelihood of treatment success. In fact, the Pap test is one of only a few cancer screening procedures that can prevent cancer by virtue of identifying and intervening upon abnormal precancerous cells in the early stages. There has been a growing prevalence of cervical cancer among HIV-positive women. Early diagnosis is essential to improving survival outcomes of women living with HIV/AIDS. The purpose of this study was to describe Pap test behaviors among women in South Carolina and examine its relationship with HIV testing.

METHODS

Behavioral Risk Factor Surveillance System (BRFSS) data from 2008 were analyzed. Chi-square tests and logistic regression analyses were performed to describe Pap test behaviors among our sample (n=3,404) of non-Hispanic White and non-Hispanic Black women (18–64 years old).

RESULTS

The majority of participants (97%) reported ever having a Pap test. Participants who reported never having a Pap test were 50% less likely to have ever been tested for HIV.

CONCLUSIONS

The participants in our study met the Healthy People 2010 target of ever having a Pap test. However, less than half of participants (42%) had ever been tested for HIV. A larger proportion of women who have had a Pap test had also been tested for HIV.

PRACTICE IMPLICATIONS

Our findings suggest that offering women an HIV test during routine Pap tests may present an opportunity to increase the number of women in South Carolina who know their HIV serostatus.

Missed opportunities for early HIV diagnosis in correctional facilities

To quantify the extent that South Carolina HIV/AIDS cases could have been diagnosed during a prior arrest we designed a retrospective population-based cohort study linking case reports from HIV/AIDS Reporting System (HARS) and the South Carolina Law Enforcement Division database. Data from individuals newly diagnosed between January 2001 and December 2005 were linked with statewide arrest records from April 1991 through November 2005. Criminal history data for this report were derived from 28 state prisons and more than 250 law enforcement agencies (jails, lockups, detention centers). Odds ratios and 95% confidence intervals were used to determine how demographic variables and arrest reasons affects receipt of HIV testing. There were 1961/4036 (48.6%) incident cases of HIV diagnosis that had at least one arrest prior to their first positive HIV test. When restricted to 1286/1961 (65.6%) individuals most likely to have been HIV-infected at the time of arrest, 592 (46%) were early testers (no AIDS within 1 year) and 694 (54%) developed AIDS more than 1 year of testing (late testers). After controlling for gender, age, race, behavioral risk and source of HIV report, the odds of being a late tester increased with age (p < 0.001). Overall, 3750 separate arrests were recorded for these 1286 individuals and 491 (13%) arrests were for drug and alcohol or sex crimes. Individuals with 4 or more arrests were more likely to be late testers when compared to those with fewer than 4 arrests (adjusted odds ratio [AOR] 3.30; 95% confidence [CI] 2.28, 4.72). Correctional facilities present considerable opportunities to identify individuals with undiagnosed HIV infection. Providing correctional facilities with the infrastructure for implementation of routine HIV testing would consequently have a significant impact on the health status of the entire community.
