RESUMO

Mortality surveillance systems can have limitations, including reporting delays, incomplete reporting, missing data, and insufficient detail on important risk or sociodemographic factors that can impact the accuracy of estimates of current trends, disease severity, and related disparities across subpopulations. The Centers for Disease Control and Prevention used multiple data systems during the COVID-19 emergency response-line-level case‒death surveillance, aggregate death surveillance, and the National Vital Statistics System-to collectively provide more comprehensive and timely information on COVID-19‒associated mortality necessary for informed decisions. This article will review in detail the line-level, aggregate, and National Vital Statistics System surveillance systems and the purpose and use of each. This retrospective review of the hybrid surveillance systems strategy may serve as an example for adaptive informational approaches needed over the course of future public health emergencies.

RESUMO

Internet-recruited gay, bisexual, and other men who have sex with men (MSM) were offered HIV self-tests (HIVSTs) after completing baseline, 3-, 6-, and 9-month follow-up surveys. The surveys asked about the use and distribution of these HIVSTs. Among 995 who reported on their distribution of HIVSTs, 667 (67.0%) distributed HIVSTs to their social network associates (SNAs), which resulted in 34 newly identified HIV infections among 2301 SNAs (1.5%). The main reasons participants reported not distributing HIVSTs included: wanting to use the HIVSTs themselves (74.9%); thinking that their SNAs would get angry or upset if offered HIVSTs (12.5%); or not knowing that they could give the HIVSTs away (11.3%). Self-testing programs can provide multiple HIVSTs and encourage the distribution of HIVST by MSM to their SNAs to increase awareness of HIV status among persons disproportionately affected by HIV.


RESUMEN: Hombres gais, bisexuales y otros hombres que indicaron tener contacto sexual con hombres (MSM, por sus siglas en inglés) fueron reclutados por el Internet y se les ofreció autopruebas del VIH (HIVST, por sus siglas en inglés) después de completar una encuestas inicial y encuestas de seguimiento a los 3, 6 y 9 meses. Las encuestas recogieron datos sobre el uso y distribución de estas autopruebas del VIH. De los 995 MSM que indicaron distribuir las autopruebas, 667 (67.0%) distribuyeron las autopruebas a personas en sus redes sociales (SNA, por sus siglas en inglés), resultando en 34 nuevas infecciones por el VIH identificadas entre 2,301 SNA (1.5%). Las razones principales por las que algunos participantes no distribuyeron las autopruebas del VIH incluyen: el deseo de utilizar las autopruebas del VIH para sí mismos (74.9%); pensar que las SNA se enfadarían o molestarían si se les ofreciesen autopruebas del VIH (12.5%); o no saber que podían distribuir las autopruebas del VIH (11.3%). Los programas que proporcionen múltiples autopruebas del VIH podrían alentar la distribución de las autopruebas por parte de los MSM a las SNA para aumentar el conocimento sobre el estado del VIH entre personas afectadas de manera desproporcionada por el VIH.

RESUMO

Background: HIV prevention programmes that include pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) and transgender women (TGW) in South Africa have not been widely implemented. Objectives: The authors examined oral PrEP uptake, adherence, and adverse events among HIV-uninfected MSM and TGW to inform intervention acceptability and feasibility. Method: In 2015, MSM and TGW in two South African cities were offered a comprehensive package of HIV prevention services, including daily oral PrEP, and were followed for one year. Different models of PrEP delivery were used at each site. Adherence was measured using self-report and pill-count data and tenofovir-diphosphate (TFV-DP) concentrations. Results: Among 135 participants who were eligible for PrEP, 82 (61%) initiated PrEP, of whom 67 (82%) were on PrEP at study end. Participants were on PrEP for a median of 294 out of 314.5 possible days (93% protected days). The median time from PrEP initiation to discontinuation or study end was 305 days (interquartile range: 232-325 days). Across the follow-up time points, 57% - 72% of participants self-reported taking protective levels of PrEP and 59% - 74% were adherent to PrEP as indicated by pill counts. Fewer (≤ 18%) achieved protective TFV-DP concentrations of ≥ 700 fmol/punch in dried blood spots. Side effects, while typically mild, were the most commonly cited reason by participants for early PrEP discontinuation. Conclusion: Many MSM and TGW initiated and maintained PrEP, demonstrating that PrEP can be successfully delivered to South African MSM and TGW in diverse programmatic contexts. Biologic adherence measures suggest MSM and TGW may experience challenges taking PrEP regularly. Counselling for coping with side effects and motivating daily pill taking is recommended to support South African MSM and TGW in achieving protection with PrEP.

RESUMO

Lesbian, gay, bisexual, and transgender (LGBT) populations have higher prevalences of health conditions associated with severe COVID-19 illness compared with non-LGBT populations (1). The potential for low vaccine confidence and coverage among LGBT populations is of concern because these persons historically experience challenges accessing, trusting, and receiving health care services (2). Data on COVID-19 vaccination among LGBT persons are limited, in part because of the lack of routine data collection on sexual orientation and gender identity at the national and state levels. During August 29-October 30, 2021, data from the National Immunization Survey Adult COVID Module (NIS-ACM) were analyzed to assess COVID-19 vaccination coverage and confidence in COVID-19 vaccines among LGBT adults aged ≥18 years. By sexual orientation, gay or lesbian adults reported higher vaccination coverage overall (85.4%) than did heterosexual adults (76.3%). By race/ethnicity, adult gay or lesbian non-Hispanic White men (94.1%) and women (88.5%), and Hispanic men (82.5%) reported higher vaccination coverage than that reported by non-Hispanic White heterosexual men (74.2%) and women (78. 6%). Among non-Hispanic Black adults, vaccination coverage was lower among gay or lesbian women (57.9%) and bisexual women (62.1%) than among heterosexual women (75.6%). Vaccination coverage was lowest among non-Hispanic Black LGBT persons across all categories of sexual orientation and gender identity. Among gay or lesbian adults and bisexual adults, vaccination coverage was lower among women (80.5% and 74.2%, respectively) than among men (88.9% and 81.7%, respectively). By gender identity, similar percentages of adults who identified as transgender or nonbinary and those who did not identify as transgender or nonbinary were vaccinated. Gay or lesbian adults and bisexual adults were more confident than were heterosexual adults in COVID-19 vaccine safety and protection; transgender or nonbinary adults were more confident in COVID-19 vaccine protection, but not safety, than were adults who did not identify as transgender or nonbinary. To prevent serious illness and death, it is important that all persons in the United States, including those in the LGBT community, stay up to date with recommended COVID-19 vaccinations.

RESUMO

Although severe COVID-19 illness and hospitalization are more common among adults, these outcomes can occur in adolescents (1). Nearly one third of adolescents aged 12-17 years hospitalized with COVID-19 during March 2020-April 2021 required intensive care, and 5% of those hospitalized required endotracheal intubation and mechanical ventilation (2). On December 11, 2020, the Food and Drug Administration (FDA) issued Emergency Use Authorization (EUA) of the Pfizer-BioNTech COVID-19 vaccine for adolescents aged 16-17 years; on May 10, 2021, the EUA was expanded to include adolescents aged 12-15 years; and on August 23, 2021, FDA granted approval of the vaccine for persons aged ≥16 years. To assess progress in adolescent COVID-19 vaccination in the United States, CDC assessed coverage with ≥1 dose* and completion of the 2-dose vaccination series† among adolescents aged 12-17 years using vaccine administration data for 49 U.S. states (all except Idaho) and the District of Columbia (DC) during December 14, 2020-July 31, 2021. As of July 31, 2021, COVID-19 vaccination coverage among U.S. adolescents aged 12-17 years was 42.4% for ≥1 dose and 31.9% for series completion. Vaccination coverage with ≥1 dose varied by state (range = 20.2% [Mississippi] to 70.1% [Vermont]) and for series completion (range = 10.7% [Mississippi] to 60.3% [Vermont]). By age group, 36.0%, 40.9%, and 50.6% of adolescents aged 12-13, 14-15, and 16-17 years, respectively, received ≥1 dose; 25.4%, 30.5%, and 40.3%, respectively, completed the vaccine series. Improving vaccination coverage and implementing COVID-19 prevention strategies are crucial to reduce COVID-19-associated morbidity and mortality among adolescents and to facilitate safer reopening of schools for in-person learning.

RESUMO

Population-based analyses of COVID-19 data, by race and ethnicity can identify and monitor disparities in COVID-19 outcomes and vaccination coverage. CDC recommends that information about race and ethnicity be collected to identify disparities and ensure equitable access to protective measures such as vaccines; however, this information is often missing in COVID-19 data reported to CDC. Baseline data collection requirements of the Office of Management and Budget's Standards for the Classification of Federal Data on Race and Ethnicity (Statistical Policy Directive No. 15) include two ethnicity categories and a minimum of five race categories (1). Using available COVID-19 case and vaccination data, CDC compared the current method for grouping persons by race and ethnicity, which prioritizes ethnicity (in alignment with the policy directive), with two alternative methods (methods A and B) that used race information when ethnicity information was missing. Method A assumed non-Hispanic ethnicity when ethnicity data were unknown or missing and used the same population groupings (denominators) for rate calculations as the current method (Hispanic persons for the Hispanic group and race category and non-Hispanic persons for the different racial groups). Method B grouped persons into ethnicity and race categories that are not mutually exclusive, unlike the current method and method A. Denominators for rate calculations using method B were Hispanic persons for the Hispanic group and persons of Hispanic or non-Hispanic ethnicity for the different racial groups. Compared with the current method, the alternative methods resulted in higher counts of COVID-19 cases and fully vaccinated persons across race categories (American Indian or Alaska Native [AI/AN], Asian, Black or African American [Black], Native Hawaiian or Other Pacific Islander [NH/PI], and White persons). When method B was used, the largest relative increase in cases (58.5%) was among AI/AN persons and the largest relative increase in the number of those fully vaccinated persons was among NH/PI persons (51.6%). Compared with the current method, method A resulted in higher cumulative incidence and vaccination coverage rates for the five racial groups. Method B resulted in decreasing cumulative incidence rates for two groups (AI/AN and NH/PI persons) and decreasing cumulative vaccination coverage rates for AI/AN persons. The rate ratio for having a case of COVID-19 by racial and ethnic group compared with that for White persons varied by method but was <1 for Asian persons and >1 for other groups across all three methods. The likelihood of being fully vaccinated was highest among NH/PI persons across all three methods. This analysis demonstrates that alternative methods for analyzing race and ethnicity data when data are incomplete can lead to different conclusions about disparities. These methods have limitations, however, and warrant further examination of potential bias and consultation with experts to identify additional methods for analyzing and tracking disparities when race and ethnicity data are incomplete.

RESUMO

Throughout the COVID-19 pandemic, older U.S. adults have been at increased risk for severe COVID-19-associated illness and death (1). On December 14, 2020, the United States began a nationwide vaccination campaign after the Food and Drug Administration's Emergency Use Authorization of Pfizer-BioNTech COVID-19 vaccine. The Advisory Committee on Immunization Practices (ACIP) recommended prioritizing health care personnel and residents of long-term care facilities, followed by essential workers and persons at risk for severe illness, including adults aged ≥65 years, in the early phases of the vaccination program (2). By May 1, 2021, 82%, 63%, and 42% of persons aged ≥65, 50-64, and 18-49 years, respectively, had received ≥1 COVID-19 vaccine dose. CDC calculated the rates of COVID-19 cases, emergency department (ED) visits, hospital admissions, and deaths by age group during November 29-December 12, 2020 (prevaccine) and April 18-May 1, 2021. The rate ratios comparing the oldest age groups (≥70 years for hospital admissions; ≥65 years for other measures) with adults aged 18-49 years were 40%, 59%, 65%, and 66% lower, respectively, in the latter period. These differential declines are likely due, in part, to higher COVID-19 vaccination coverage among older adults, highlighting the potential benefits of rapidly increasing vaccination coverage.

RESUMO

INTRODUCTION: Men who have sex with men (MSM) and transgender women (TGW) experience high incidence and prevalence of sexually transmitted infections (STI), and data are needed to understand risk factors for STIs in these populations. The Sibanye Health Project was conducted in Cape Town and Port Elizabeth, South Africa from 2015 to 2016 to develop and test a package of HIV prevention interventions for MSM and TGW. We describe the incidence, prevalence and symptoms of Chlamydia trachomatis (CT), Neisseria gonorrhea (NG) and syphilis observed during the study. METHODS: Participants completed HIV testing at baseline. All participants who were HIV negative were followed prospectively. Additionally, a sample of participants identified as living with HIV at baseline was selected to be followed prospectively so that the prospective cohort was approximately 20% HIV positive; the remaining participants identified as HIV positive at baseline were not followed prospectively. Prospective participants were followed for 12 months and returned for clinic-based STI/HIV testing and assessment of STI symptoms at months 6 and 12. Additional HIV/STI testing visits could be scheduled at participant request. RESULTS: Following consent, a total of 292 participants attended a baseline visit (mean age = 26 years), and 201 were enrolled for the 12-month prospective study. Acceptance of screening for syphilis and urethral NG/CT was near universal, though acceptance of screening for rectal NG/CT was lower (194/292; 66%). Prevalence of urethral CT and NG at baseline was 10% (29/289) and 3% (8/288) respectively; incidence of urethral CT and NG was 12.8/100 person-years (PY) and 7.1/100 PY respectively. Prevalence of rectal CT and NG at baseline was 25% (47/189) and 16% (30/189) respectively; incidence of rectal CT and NG was 33.4/100 PY and 26.8/100 PY respectively. Prevalence of syphilis at baseline was 17% (45/258) and incidence was 8.2/100 PY. 91%, 95% and 97% of diagnosed rectal NG/CT, urethral NG/CT and syphilis infections, respectively, were clinically asymptomatic. CONCLUSIONS: Prevalence and incidence of urethral and rectal STIs were high among these South African MSM and TGW, and were similar to rates in other settings in the world. Clinical symptoms from these infections were rare, highlighting limitations of syndromic surveillance and suggesting the need for presumptive testing and/or treatment to address the STI epidemic among MSM/TGW in South Africa.

RESUMO

INTRODUCTION: Men who have sex with men (MSM) and transgender women (TGW) are at increased risk for acquiring HIV, but there are limited HIV incidence data for these key populations in Africa. Understanding HIV prevalence and incidence provides important context for designing HIV prevention strategies, including pre-exposure prophylaxis (PrEP) programmes. We describe HIV prevalence, awareness of HIV infection, HIV incidence and associated factors for a cohort of MSM and TGW in Cape Town and Port Elizabeth, South Africa. METHODS: From 2015 to 2016, MSM and TGW in Cape Town and Port Elizabeth were enrolled and prospectively followed for 12 months, receiving a comprehensive package of HIV prevention services. HIV testing was conducted at baseline and at follow-up visits (targeted for three, six and twelve months). All HIV-negative PrEP-eligible participants were offered PrEP enrolment during the first four months of study participation. We determined HIV prevalence among participants at baseline, and incidence by repeat screening of initially HIV-negative participants with HIV tests at three, six and twelve months. RESULTS: Among 292 participants enrolled, HIV prevalence was high (43%; 95% CI: 38 to 49) and awareness of HIV status was low (50%). The 167 HIV-negative participants who were followed prospectively for 144.7 person-years; nine incident HIV infections were documented. Overall annual incidence was 6.2% (CI: 2.8 to 11.8) and did not differ by city. Annual HIV incidence was significantly higher for younger (18 to 19 years) MSM and TGW (MSM: 21.8% (CI: 1.2 to 100); TGW: 31.0 (CI: 3.7, 111.2)). About half of participants started PrEP during the study; the annual incidence of HIV among 82 (49%) PrEP starters was 3.6% (CI: 0.4, 13.1) and among those who did not start PrEP was 7.8% (CI: 3.1, 16.1). CONCLUSIONS: HIV incidence was high among MSM and TGW in the context of receiving a comprehensive package of prevention interventions and offering of PrEP. PrEP uptake was high; the observed incidence of HIV in those who started PrEP was about half the incidence of HIV in those who did not. Future implementation-oriented studies should focus on decisions to start and continue PrEP for those at highest risk, including young MSM.

RESUMO

BACKGROUND: Data to Care (D2C) is a public health strategy that uses HIV surveillance and other data to identify persons living with HIV who are "not in care" to link them to medical care or other services. To support health department implementation of D2C, the Centers for Disease Control and Prevention supported direct technical assistance (TA) to build health department D2C capacity. METHODS: Between 2013 and 2017, 2 contracting organizations worked with the Centers for Disease Control and Prevention to provide intensive D2C TA to 20 US health departments. A requirement for applying for TA was the mandatory reporting of all CD4 T-lymphocyte and HIV viral load test results by laboratories to the health department's HIV surveillance system. Health department selection criteria included organizational factors; jurisdiction laws/policies about data confidentiality and sharing; and HIV morbidity level. RESULTS: Peer-to-peer consultation, technical consultation, training, information transfer, materials development, materials distribution, and technology transfer were methods used for delivering TA based on the health department's needs and preferences. TA supported health department progress in areas such as confidentiality and data security, stakeholder engagement, quality of HIV surveillance data, data sharing, staffing resources, creating "not-in-care" lists, and program evaluation. CONCLUSION: Developing D2C programs is not a linear process, and there is no one standardized approach. Health departments made the most rapid progress when TA included peer-to-peer support among health departments. Participation in this project facilitated, in some cases for the first time, collaboration between staff across HIV surveillance, prevention, and care programs.

RESUMO

HIV-positive men who have sex with men (MSM) were recruited on www.Facebook.com and www.Poz.com to give HIV self-tests to their contacts. Study participants completed a baseline survey, were given two self-tests, and completed a survey 2 months later. Of 133 eligible men, 40 (30%) completed both surveys. Most participants were 30-54 years old and non-Hispanic white. Some had a detectable viral load (n = 4), had condomless anal sex with male partners of negative or unknown status (n = 17), and had met anal sex partners at gay dating websites (n = 23). Of 80 self-tests given to participants, 59 (74%) were distributed, primarily to non-Hispanic white MSM, 30-54 years old who were friends. Participants reported results from 31 distributed tests; 2 sex partners of participants had positive results. Participants indicated these two persons were unaware of their infections. Expanding recruitment websites might reach non-white MSM. Unrecognized infections were identified through online recruitment and self-test distribution via HIV-positive persons.

RESUMO

HIV testing is the gateway into both prevention and treatment services. It is important to understand how men who have sex with men (MSM) perceive HIV self-tests. We conducted focus groups and individual interviews to collect feedback on two HIV self-tests, and on a dried blood spot (DBS) specimen collection kit. Perceptions and attitudes around HIV self-testing (HIVST), and willingness to distribute HIV self-tests to others were assessed. MSM reported HIVST to be complementary to facility-based testing, and liked this approach because it offers privacy and convenience, does not require counseling, and could lead to linkage to care. However, they also had concerns around the accuracy of HIV self-tests, their cost, and receiving a positive test result without immediate access to follow-up services. Despite these issues, they perceived HIVST as a positive addition to their HIV prevention toolbox.

RESUMO

In the United States, an estimated 67% of new HIV diagnoses are among men who have sex with men (MSM), however 25% of HIV-positive MSM in the 2014 National HIV Behavioral Surveillance Survey were unaware of their infection. HIV self-testing (HIVST) with rapid diagnostic tests (RDTs) may facilitate access to HIV testing. We evaluated the ability of 22 MSM to conduct two HIV RDTs (OraQuick ® In-Home HIV Test and a home-use prototype of Sure Check ® HIV 1/2 Assay), interpret sample images of test results, and collect a dried blood spot (DBS) specimen. While some participants did not follow every direction, most participants were able to conduct HIVST and correctly interpret their results. Interpretation of panels of RDT images was especially difficult when the "control" line was missing, and 27% of DBS cards produced were rated as of bad quality. Modifications to the DBS instructions were necessary prior to evaluating the performance of these tests in real-world settings.

RESUMO

Peer-driven HIV prevention strategies can be effective in identifying high-risk persons with undiagnosed infections. Besides individual self-testing, other potential uses of rapid home HIV test kits include distributing them, and testing with others within one's social or sexual networks. We sought to identify factors associated with the willingness to engage in these alternative activities among men who have sex with men (MSM) in the United States. From May to October 2014, we surveyed 828 HIV-negative or unknown status MSM about multiple aspects of rapid home HIV testing. A greater proportion indicated being likely to distribute free oral fluid (OF) tests compared to free finger-stick blood (FSB) tests (91% versus 79%), and almost three-fourths (72%) reported being likely to test with their friends or sex partners in the future. MSM not identifying as homosexual/gay were less willing to distribute OF tests, and those with lower educational attainment were more willing to distribute FSB tests. MSM unaware of their HIV status were less likely to report potentially testing with others using free rapid home HIV tests compared to those who were HIV-negative. Finally, MSM willing to self-test were more likely to report future test kit distribution, and those willing to distribute kits were more likely to report potentially testing with others. Engaging individuals with positive attitudes towards these strategies in prevention efforts could help increase HIV testing levels among MSM. A greater understanding of the potential public health impact of rapid home HIV test kits is necessary.

RESUMO

BACKGROUND: Women living with HIV infection are at higher risk for cervical cancer, an AIDS-defining diagnosis. We examined the prevalence of cervical cancer and sexually transmitted disease (STD) screening among human immunodeficiency virus (HIV)-infected women and factors associated with the receipt of Papanicolaou (Pap) tests. METHODS: We did a cross-sectional analysis of weighted data from a sample of HIV-infected adults receiving outpatient medical care. We used matched interview (report of Pap test) and medical record data (STD screenings) from HIV-infected women. We performed logistic regression to compute adjusted prevalence ratios and 95% confidence intervals for the association between demographic, behavioral, and clinical factors and receipt of Pap tests among HIV-infected women. RESULTS: Data were available for 2,270 women, who represent 112,894 HIV-infected women; 62% were African American, 17% were Hispanic/Latina, and 18% were white. Most (78%) reported having a Pap test in the past year. Among sexually active women (n = 1234), 20% reported sex without condoms, 27% were screened for gonorrhea, and 29% were screened for chlamydia. Being screened for STDs was less likely among women who did not have a Pap test in the past year (adjusted prevalence ratios 0.82, 95% confidence interval 0.77-0.87). Women who were ≥50 years of age and reported income above federal poverty level, no sexual activity, depression, no HIV care from an obstetrician/gynecologist, and no documented STD tests, were less likely to report a Pap test (p < 0.05). CONCLUSIONS: Screening for cervical cancer and STDs among HIV-infected women is suboptimal. Clinical visits for Pap tests are an important opportunity for HIV-infected sexually active women to also receive STD screenings and counseling regarding condoms.

RESUMO

OBJECTIVE: To determine which of 3 HIV testing and counseling (HTC) models in outpatient departments (OPDs) increases HIV testing and entry of newly identified HIV-infected patients into care. DESIGN: Randomized trial of HTC interventions. METHODS: Thirty-six OPDs in South Africa, Tanzania, and Uganda were randomly assigned to 3 different HTC models: (A) health care providers referred eligible patients (aged 18-49, not tested in the past year, not known HIV positive) to on-site voluntary counseling and testing for HTC offered and provided by voluntary counseling and testing counselors after clinical consultation; (B) health care providers offered and provided HTC to eligible patients during clinical consultation; and (C) nurse or lay counselors offered and provided HTC to eligible patients before clinical consultation. Data were collected from October 2011 to September 2012. We describe testing eligibility and acceptance, HIV prevalence, and referral and entry into care. Chi-square analyses were conducted to examine differences by model. RESULTS: Of 79,910 patients, 45% were age eligible and 16,099 (45%) age eligibles were tested. Ten percent tested HIV positive. Significant differences were found in percent tested by model. The proportion of age eligible patients tested by Project STATUS was highest for model C (54.1%, 95% confidence interval [CI]: 42.4 to 65.9), followed by model A (41.7%, 95% CI: 30.7 to 52.8), and then model B (33.9%, 95% CI: 25.7 to 42.1). Of the 1596 newly identified HIV positive patients, 94% were referred to care (96.1% in model A, 94.7% in model B, and 94.9% in model C), and 58% entered on-site care (74.4% in model A, 54.8% in model B, and 55.6% in model C) with no significant differences in referrals or care entry by model. CONCLUSIONS: Model C resulted in the highest proportion of all age-eligible patients receiving a test. Although 94% of STATUS patients with a positive test result were referred to care, only 58% entered care. We found no differences in patients entering care by HTC model. Routine HTC in OPDs is acceptable to patients and effective for identifying HIV-infected persons, but additional efforts are needed to increase entry to care.

RESUMO

OBJECTIVE: To describe the prevalence and association of sexual risk behaviours and viral suppression among HIV-infected adults in the United States. DESIGN: Cross-sectional analysis of weighted data from a probability sample of HIV-infected adults receiving outpatient medical care. The facility and patient response rates were 76 and 51%, respectively. METHODS: We analysed 2009 interview and medical record data. Sexual behaviours were self-reported in the past 12 months. Viral suppression was defined as all viral load measurements in the medical record during the past 12 months less than 200 copies/ml. RESULTS: An estimated 98 022 (24%) HIV-infected adults engaged in unprotected vaginal or anal sex; 50 953 (12%) engaged in unprotected vaginal or anal sex with at least one partner of negative or unknown HIV status; 23 933 (6%) did so while not virally suppressed. Persons who were virally suppressed were less likely than persons who were not suppressed to engage in vaginal or anal sex [prevalence ratio, 0.88; 95% confidence interval (CI), 0.82-0.93]; unprotected vaginal or anal sex (prevalence ratio, 0.85; 95% CI, 0.73-0.98); and unprotected vaginal or anal sex with a partner of negative or unknown HIV status (prevalence ratio, 0.79; 95% CI, 0.64-0.99). CONCLUSION: The majority of HIV-infected adults receiving medical care in the U.S. did not engage in sexual risk behaviours that have the potential to transmit HIV, and of the 12% who did, approximately half were not virally suppressed. Persons who were virally suppressed were less likely than persons who were not suppressed to engage in sexual risk behaviours.

RESUMO

In 2006, CDC recommended HIV screening as part of routine medical care for all persons aged 13-64 years. We examined adherence to the recommendations among a sample of HIV care providers in the US to determine if known providers of HIV care are offering routine HIV testing in outpatient settings. Data were from the CDC's Medical Monitoring Project Provider Survey, administered to physicians, nurse practitioners and physician assistants from June-September 2009. We assessed bivariate associations between testing behaviors and provider and practice characteristics and used multivariate regression to determine factors associated with offering HIV screening to all patients aged 13-64 years. Sixty percent of providers reported offering HIV screening to all patients 13 to 64 years of age. Being a nurse practitioner (aOR = 5.6, 95% CI = 2.6-11.9) compared to physician, age<39 (aOR = 1.9, 95% CI = 1.0-3.5) or 39-49 (aOR = 2.1, 95% CI = 1.4-3.3) compared with ≥50 years, and black race (aOR = 2.6, 95% CI = 1.2-6.0) compared with white race was associated with offering testing to all patients. Providers with low (aOR = 0.2, 95% CI = 0.1-0.3) or medium (aOR = 0.4, 95% CI = 0.2-0.6) HIV-infected patient loads were less likely to offer HIV testing to all patients compared with providers with high patient loads. Many providers of HIV care are still conducting risk-based rather than routine testing. We found that provider profession, age, race, and HIV-infected patient load were associated with offering HIV testing. Health care providers should use patient encounters as an opportunity to offer routine HIV testing to patients as outlined in CDC's revised recommendations for HIV testing in health care settings.

RESUMO

PROBLEM: As of December 31, 2008, an estimated 663,084 persons were living with a diagnosis of human immunodeficiency virus (HIV) infection in the 40 U.S. states that have had confidential name-based HIV infection reporting since at least January 2006. Although HIV surveillance programs in the United States collect information about persons who have received a diagnosis of HIV infection and acquired immunodeficiency syndrome (AIDS), supplemental surveillance projects are needed to collect information about care-seeking behaviors, health-care use, and other behaviors among persons living with HIV. Data on the clinical and behavioral characteristics of persons receiving medical care for HIV infection are critical to reduce HIV-related morbidity and mortality and for program planning to allocate services and resources, guide prevention planning, assess unmet medical and ancillary service needs, and help develop intervention programs and health policies at the local, state, and national levels. REPORTING PERIOD COVERED: Data were collected during June 2007-September 2008 for patients who received medical care in 2007 (sampled from January 1-April 30). DESCRIPTION OF THE SYSTEM: The Medical Monitoring Project (MMP) is an ongoing, multisite supplemental surveillance project that assesses behaviors, clinical characteristics, and quality of care of HIV-infected persons who are receiving medical care. Participants must be aged ≥ 18 years and have received medical care at sampled facilities that provide HIV medical care within participating MMP project areas. Self-reported behavioral and selected clinical data are collected using an in-person interview. A total of 26 project areas in 19 states and Puerto Rico were funded to collect data during the 2007 MMP data collection cycle. RESULTS: The results from the 2007 MMP cycle indicated that among 3,643 participants, a total of 3,040 (84%) had some form of health insurance or coverage during the 12 months before the interview; of these, 45% reported having Medicaid, 37% reported having private health insurance or coverage through a health maintenance organization, and 30% reported having Medicare. A total of 3,091 (85%) of the participants were currently taking antiretroviral medications. Among 3,609 participants who reported ever having a CD4 T-lymphocyte test, 2,996 (83%) reported having three or more CD4 T-lymphocyte tests in the 12 months before the interview. Among 3,567 participants who reported ever having an HIV viral load test, 2,946 (83%) reported having three or more HIV viral load tests in the 12 months before the interview. Among 3,643 participants, 45% needed HIV case management, 33% needed mental health counseling, and 32% needed assistance finding dental services during the 12 months before the interview; 8%, 13%, and 25% of these participants who needed the services, respectively, had not received these services by the time of the interview. Noninjection drugs were used for nonmedical purposes by 1,117 (31%) participants during the 12 months before the interview, and 122 (3%) participants had used injection drugs for nonmedical purposes. Unprotected anal intercourse was reported by 527 (54%) of 970 men who reported having anal sex with a man during the 12 months before the interview. Unprotected anal or vaginal intercourse was reported by 176 (32%) of the 553 men who reported having anal or vaginal intercourse with a woman during the 12 months before the interview. Unprotected anal or vaginal intercourse was reported by 216 (42%) of the 516 women who reported having anal or vaginal intercourse with a man during the 12 months before the interview. INTERPRETATION: The findings in this report indicate that in 2007, most persons with HIV infection who were receiving medical care were taking antiretroviral therapy and had some form of health insurance or coverage; however, some persons were not receiving needed critical ancillary services, such as HIV case management or help finding dental services. In addition, some persons living with HIV infection engaged in behaviors, such as unprotected sex, that increase the risk for transmitting HIV to sexual partners, and some used noninjection or injection drugs for nonmedical purposes, which might decrease adherence to antiretroviral therapy and increase health-risk behaviors. PUBLIC HEALTH ACTIONS: MMP data can be used to monitor the national HIV/AIDS strategy goal of increasing access to care and optimizing health outcomes among persons living with HIV. Persons infected with HIV who are not receiving needed ancillary services highlight missed opportunities for access to care and other supportive services, information that can be used to advocate for additional resources. Drug use among persons with HIV infection underscores the continued need for substance abuse treatment services for this population. In addition, prevention services and programs are needed to decrease the number of HIV-infected persons engaging in unprotected sex. The data in this report can be included in local, state, and national HIV/AIDS epidemiologic profiles and shared with community stakeholders. Although data from the 2007 MMP cycle might not be representative of all persons receiving medical care for HIV infection in the United States or in the individual project areas, future MMP cycles are expected to yield weighted national estimates representing all HIV-infected persons receiving medical care in the United States.

RESUMO

BACKGROUND: Visiting a medical provider less frequently than clinical circumstances would suggest is appropriate has been reported to be associated with worse clinical outcomes for patients living with HIV infection. Patients with less frequent attendance to HIV care also may be systematically underrepresented in research or surveillance studies that enroll patients sequentially over a specified enrollment period - for example several months. For both reasons, understanding factors associated with time to care visit is important. METHODS: We used data from the Adult and Adolescent Spectrum of HIV Disease (ASD) project, a multi-site clinical outcomes surveillance system that enrolled and followed patients in care for HIV prospectively from 1990 to 2004. For this analysis, we used data from all patients observed in ASD at least one time before 1 January 2003, and who had at least one HIV care visit in 2003. We documented time to first annual HIV care visit for each patient, and used Kaplan-Meier plots and proportional hazards regression to describe factors associated with longer time to care visit. RESULTS: A total of 12,135 patients had ≥1 care visit during 2003 and were included in the analysis. Of these, 81%, 88%, and 95% had their first visit within three, four, and six months, respectively. In multivariate analysis, having a delayed (later) care visit was associated with not ever having had an AIDS diagnosis, having an HIV RNA concentration ≥10,000 copies/mL, having a current CD4 count <100 cells/µL, having no health insurance, and not being currently prescribed antiretroviral therapy. Having a delayed care visit was not associated with race/ethnicity or age. CONCLUSIONS: Having a delayed first annual HIV care visit was associated with higher viremia, lower CD4 cell count, and lack of health insurance. Interventions to address these factors are likely to ameliorate some of the consequences of HIV. For studies enrolling patients in care for HIV over a finite time period, an enrollment period of four-six months should sufficiently reflect the patient population seen in a one-year period, including those attending care infrequently.
