HIV testing among pregnant women with prenatal care in the United States: An analysis of the 2011-2017 National Survey of Family Growth

Although there has been significant progress in reducing perinatal human immunodeficiency virus (HIV) transmission, the United States is yet to meet the proposed elimination goal of less than one infection per 100,000 live births. Failure to screen all pregnant women for HIV as recommended by the Centers for Disease Control and Prevention can result in missed opportunities for preventing vertical transmission of HIV with antiretroviral drugs. Using the 2011-2017 National Survey of Family Growth, this study examined HIV testing among pregnant women during prenatal care. We estimated the weighted proportion of self-reported HIV testing among women whose last pregnancy ended within 12 months prior to the interview. Logistic regression models were used to determine the factors associated with HIV testing. Of the 1566 women included in the study, 76.4% (95% confidence intervals [CI] = 72.8-80.0) reported receiving an HIV test during prenatal care. In the multivariable regression model, high school diploma (adjusted odds ratio [aOR] = 1.9, 95% CI = 1.1-3.1), two completed pregnancies (aOR = 1.7, 95% CI = 1.1-2.7), health insurance coverage in the last 12 months (aOR = 1.6, 95% CI = 1.0-2.6), Hispanic race/ethnicity (aOR = 2.8, 95% CI = 1.8-4.4), and non-Hispanic black race/ethnicity (aOR = 2.2, 95% CI = 1.3-3.8) were associated with higher odds of reporting being tested for HIV. However, household income of 300% or more of the federal poverty level (aOR = 0.6, 95% CI = 0.3-0.9) and urban residence (aOR = 0.5, 95% CI = 0.3-0.9) were associated with lower odds of reporting HIV testing. These findings suggest that HIV testing among pregnant women during prenatal care is not universal and may affect achieving the goal of elimination of mother-to-child transmission of HIV in the United States.

HIV test offers and acceptance: New York State findings from the behavioral risk factor surveillance system and the National HIV behavioral surveillance, 2011-2012

BACKGROUND

The New York State HIV testing law requires that patients aged 13-64 years be offered HIV testing in health care settings. We investigated the extent to which HIV testing was offered and accepted during the 24 months after law enactment.

METHODS

We added local questions to the Behavioral Risk Factor Surveillance System (BRFSS) and the National HIV Behavioral Surveillance (NHBS) surveys asking respondents aged 18-64 years whether they were offered an HIV test in health care settings, and whether they had accepted testing. Statewide prevalence estimates of test offers and acceptance were obtained from a combined 2011-2012 BRFSS sample (N = 6,223). Local estimates for 2 high-risk populations were obtained from NHBS 2011 men who have sex with men (N = 329) and 2012 injection drug users (N = 188) samples.

RESULTS

BRFSS data showed that 73% of New Yorkers received care in any health care setting in the past 12 months, of whom 25% were offered an HIV test. Sixty percent accepted the test when offered. The levels of test offer increased from 20% to 29% over time, whereas acceptance levels decreased from 68% to 53%. NHBS data showed that 81% of men who have sex with men received care, of whom 43% were offered an HIV test. Eighty-eight percent accepted the test when offered. Eighty-five percent of injection drug users received care, of whom 63% were offered an HIV test, and 63% accepted the test when offered.

CONCLUSIONS

We found evidence of partial and increasing implementation of the HIV testing law. Importantly, these studies demonstrated New Yorkers' willingness to accept an offered HIV test as part of routine care in health care settings.

Perinatal HIV testing among African American, Caucasian, Hmong and Latina women: exploring the role of health-care services, information sources and perceptions of HIV/AIDS

Perinatal HIV transmission disproportionately affects African American, Latina and potentially Hmong women in the United States. Understanding racially and ethnically diverse women's perceptions of and experiences with perinatal health care, HIV testing and HIV/AIDS may inform effective health communications to reduce the risk of perinatal HIV transmission among disproportionate risk groups. We used a qualitative descriptive research design with content analysis of five focus groups of African American, Caucasian, Hmong and Latina women of reproductive age with low socioeconomic status distinguished by their race/ethnicity or HIV status. A purposive stratified sample of 37 women shared their health-care experiences, health information sources and perceptions of HIV testing and HIV/AIDS. Women's responses highlighted the importance of developing and leveraging trusted provider and community-based relationships and assessing a woman's beliefs and values in her sociocultural context, to ensure clear, consistent and relevant communications. Perinatal health communications that are culturally sensitive and based on an assessment of women's knowledge and understanding of perinatal health and HIV/AIDS may be an effective tool for health educators addressing racial and ethnic disparities in perinatal HIV transmission.

HIV testing among Deep South residents with serious psychological distress

OBJECTIVE

To describe the prevalence of serious psychological distress among Deep South residents and human immunodeficiency virus (HIV) testing among Deep South residents with serious psychological distress.

METHODS

Data from the 2007 Behavioral Risk Factor Surveillance System (BRFSS) survey from Georgia, Louisiana, Mississippi, and South Carolina were used for this study. Andersen's behavioral model of health care use provided the conceptual framework for the study. The Kessler 6 was used to dichotomize the sample as having or not having serious psychological distress. chi2 Test and multivariate logistic regression analyses were performed on the weighted data.

RESULTS

Only 5.7% of our sample had experienced serious psychological distress in the past 30 days. A majority proportion of persons with serious psychological distress (54.9%) had been tested for HIV. HIV testing was slightly more prevalent among males with serious psychological distress (63%) than females with serious psychological distress (60%). Predisposing factors (age, race/ethnicity, and urbanization) were confounders of HIV testing among both males and females with serious psychological distress. Enabling factors (income, health care access) were only confounders of HIV testing among males with serious psychological distress.

CONCLUSION

Future HIV prevention and management efforts should consider the potential role of concurrent serious psychological distress in impacting an individual's daily life and health activities such as self-care, caring for family, and maintaining employment.

Acceptability of routine offer of HIV Testing (opt-out approach) among pregnant women in the Wa municipality

BACKGROUND

With the introduction of the opt out HIV testing policy in Ghana, the HIV test is offered routinely to all pregnant women unless they decline testing.

OBJECTIVE

To assess acceptability of the routine offer of HIV testing antenatal clinic (ANC) clients in the Wa municipality, Ghana.

DESIGN

Cross-sectional study of 270 randomly selected ANC attendees.

RESULTS

More than 90% of respondents were in favour of the opt-out policy. The most commonly cited reasons were that it would help pregnant women know their status and facilitate prevention of mother to child transmission of HIV (PMTCT). About 60% of respondents had tested for HIV in the current pregnancy with more than 90% reporting that the test was offered them in a manner in which they could have refused the test. HIV testing in the current pregnancy was associated with having heard of the opt-out policy (p <0.001) and awareness that the test was offered at the facility (p < 0.001), but there was no relationship with educational level. Out of the 112 clients who had not had HIV test in the current pregnancy, 61.8% claimed the test had not been offered to them while 82.4% expressed willingness to have the test done if offered.

CONCLUSION

The opt-out HIV testing policy is acceptable to the pregnant women surveyed in the Wa municipality. A well laid out process to ensure that all pregnant women are routinely offered HIV testing at the ANC may help minimize missed opportunities for utilizing PMTCT services.

HIV testing for pregnant women: a rights-based analysis of national policies

Ethical and human rights concerns have been expressed regarding the global shift in policies on HIV testing of pregnant women. The main purpose of this research was to conduct a policy analysis using a human rights-based approach of national policies for HIV testing of pregnant women. We collected HIV testing policies from 19 countries including: Cambodia, China, Guyana, Haiti, India, Jamaica, Kenya, Moldova, Papua New Guinea, Russian Federation, South Africa, Sudan, Swaziland, Tanzania, Ukraine, United States, Uzbekistan, Zambia and Zimbabwe. We analysed the HIV testing policies using a standardised framework that focused on government obligations to respect, protect and fulfil. Our results highlight the need for more attention to issues of pregnant women's autonomy in consenting to HIV testing, confidentiality in antenatal care settings and provision of counselling and care services. We conclude with a discussion about potential implications of the current testing policies and provide recommendations for ways that HIV testing policies can more effectively uphold the human rights of pregnant women.

The impact of retention in early HIV medical care on viro-immunological parameters and survival: a statewide study

Current literature on retention in HIV care fails to account for patients who continually/simultaneously access different providers. This statewide study examined retention in early HIV medical care and its impact on viro-immunological improvement and survival outcomes. It was a retrospective study of South Carolina residents ≥13 years old who were diagnosed with HIV infection in 2004-2007 and initially entered in care. CD4 count/percent and viral load (VL) tests that must be reported to the South Carolina HIV surveillance database were used as a proxy for a clinical visit. Retention was defined as at least one visit in each of four 6-month periods over 2 years postlinkage. Retention rates were categorized as "optimal" (visits in four intervals), "suboptimal" (visits in three intervals), sporadic (visits in two or one intervals), and "dropout" (no visits). Logistic regression and Cox proportional analyses were used to examine retention. Of the 2197 persons, about 50% failed to maintain optimal retention in care postlinkage. Male gender, nonwhite race/ethnicity, younger age, delayed linkage, and HIV-only status were significant predictors of lower rate of retention. Mean decrease in baseline log(10) VL was greater among those with optimal compared to suboptimal (-1.81 vs. -1.42; p < 0.001) and sporadic retention (-1.81 vs. -0.70; p < 0.001). Mean increase in baseline CD4 count was greater in optimal retention compared to suboptimal (169.70 vs. 107.5; p < 0.001) and sporadic retention (169.70 vs. 2.43; p < 0.001). Increased risk of mortality was associated with sporadic retention (aHR 2.91; 95% CI 1.54-5.50) and "dropout" (aHR 4.00; 95% CI 1.50-10.65). Rate of poor retention in early HIV medical care was relatively higher than reported in clinic-based data. Increasing the rate of retention in early HIV care could substantially improve viro-immunological parameters and survival outcomes.

Influence of timing of seasonal influenza vaccination on effectiveness and cost-effectiveness in pregnancy

The purpose of this review was to estimate the impact of timing of seasonal influenza vaccination during pregnancy on health and economic outcomes. Cost-effectiveness analysis with a dynamic model of the US population of pregnant women and infants who were <6 months incorporated seasonal variation in influenza incidence. Compared with no vaccination, seasonal influenza vaccination in pregnancy costs $70,089 per quality-adjusted life year. Most of the benefit for infants was limited to those whose mothers were vaccinated within the first 4 weeks of vaccine availability. Once all women who were pregnant at the time of vaccine availability were vaccinated, vaccination of newly pregnant women had benefits for mothers but not infants. Delay of vaccination beyond November reduced both effectiveness and cost-effectiveness. The greatest population benefit from seasonal influenza vaccination in pregnancy was realized if pregnant women were vaccinated as soon as possible after trivalent inactivated influenza vaccine became available. Efforts to increase vaccine rates should be concentrated early in the influenza season.

Need to improve routine HIV testing of U.S. Veterans in care: results of an Internet survey

Late diagnosis of HIV infection contributes to poor medical outcomes and helps sustain continued transmission of virus. Published evidence suggests that despite current public health recommendations, patients receiving care in the Veterans Health Administration (VHA) system are not being routinely tested for HIV infection. Using a sample of computer-literate veterans, we conducted a survey of recent testing experiences. My HealtheVet (MHV) is a secure website allowing registered Veterans to access limited personal VHA health information. Using the American Customer Satisfaction Index (ACSI) Survey, an electronic questionnaire on "health screening" was conducted in late Fall/early winter 2008-2009. A random sample (4%) of MHV users were surveyed; approximately 17% completed the survey and responses ranged from 31,237 to 33,074. Only 9% of the respondents indicated that they had been offered a test for HIV in the last 12 months compared to 83% who had been offered cholesterol screening, 65% blood sugar screening and 19% who had been offered testing for Hepatitis C virus (HCV). Of those who had been offered HIV testing, 91% indicated that they'd had the test performed. Of note, the percentage of respondents who indicated that they would "very likely" accept a test, if offered, was similar for HIV (73%), HCV (79%), cholesterol (75%), and blood sugar (75%). Although these results cannot be generalized to all Veterans in care, they suggest that routine testing for HIV has not been taking place and support recent VHA policy changes to remove barriers to HIV testing.

Pregnancy and HIV infection in young women in North Carolina

OBJECTIVES

We described young women in North Carolina (NC) who were pregnant at the time of diagnosis with human immunodeficiency virus (HIV) infection to identify an at-risk population that could be targeted for increased HIV screening. We investigated the combined effect of partner counseling and referral services (PCRS) and comprehensive prenatal HIV screening.

METHODS

We conducted a retrospective review of PCRS charts on young women newly diagnosed with HIV in NC between 2002 and 2005. We determined the prevalence of pregnancy in the study sample and conducted bivariate analyses to assess predictors of pregnancy at the time of HIV diagnosis, calculating prevalence ratios (PRs) with 95% confidence intervals (CIs). We analyzed results of partner notification efforts, including timing and stage of diagnosis of HIV-positive partners.

RESULTS

During the four-year period, 551 women aged 18-30 years were newly diagnosed with HIV; 30% were pregnant at the time of HIV diagnosis. Pregnant women were more likely to be Hispanic (PR=1.58, 95% CI 1.15, 2.17) and not report typical risk factors. Fourteen percent of pregnant women's partners had an undiagnosed infection compared with slightly more than 8% of nonpregnant women's partners (p<0.01).

CONCLUSIONS

Ethnic differences in co-diagnosis of pregnancy and HIV suggest that young Hispanic women may have differential access to and acceptance of routine HIV screening. Comprehensive prenatal screening combined with partner notification can be effective in reaching infected male partners who are undiagnosed.

Women's acceptability and husband's support of rapid HIV testing of pregnant women in India

This study examined acceptability among pregnant women and their husbands for HIV testing within the antenatal clinic (ANC) and delivery room (DR) of a government hospital in Pune, India from September 2000 to November 2001. Acceptance of HIV counselling and testing was high with 83% of eligible women in the antenatal clinic (851 of 1025) and 68% of eligible women in the delivery room (417 of 613) getting tested on the same day. Structured interviews were conducted on 94 pregnant women in the ANC 50 women in the DR, and 100 husbands who accompanied their wives in the ANC. These data indicated that the majority of women agreed to be tested independently without the need for further consultation with family members, a view that was strongly supported in this sub-sample of accompanying husbands. For delivering women who were not progressing in their labour, counselling in the DR allowed for individual attention to questions and concerns thereby making counselling in the DR feasible.

Examining the effectiveness of an opt-in approach to prenatal human immunodeficiency virus screening

OBJECTIVE

We sought to determine the prenatal human immunodeficiency virus (HIV) screening rate when using an opt-in policy and to find variables predictive of screening.

STUDY DESIGN

This was a case-control study examining gravid women with a prenatal visit and a delivery at our hospital in 2005. Cases were defined as women who did not undergo HIV screening during the first or second prenatal visit. Our institution used an opt-in approach to HIV screening.

RESULTS

Overall, 71% (291/412) of women underwent HIV screening at the first or second prenatal visit. Patient refusal was the most common reason for not being screened (15%; 62/412). Women who were < or = 25 years old, were unmarried, and received care from maternal-fetal medicine attendings or family practitioners were more likely to undergo HIV screening.

CONCLUSION

With an opt-in approach, 29% of women were not screened for HIV during their early prenatal care. An opt-in policy also leads to screening rates that are provider dependent.

The prevention of mother-to-child HIV transmission programme in Lilongwe, Malawi: why do so many women drop out

Mother-to-child transmission of HIV constitutes a substantial burden of new HIV infections in sub-Saharan Africa, and losses to follow-up continue to undermine prevention of mother-to-child transmission of HIV (PMTCT) programmes. This qualitative study sought to clarify why some women who were enrolled in a PMTCT programme in Lilongwe, Malawi, did not fully participate in follow-up visits in the first six months after testing HIV-positive. Twenty-eight women, 14 who participated fully in the programme and 14 who dropped out, were purposively selected for in-depth interview at two clinics. Focus group discussions with 15 previously interviewed and 13 newly recruited women were also conducted. Discussions with 12 of the women's husbands were also carried out. Although the proportion of women being tested has reportedly increased, losses to follow-up have shifted and are occurring at every step after testing. Major emerging themes associated with dropping out of the PMTCT programme within six months after delivery were to avoid involuntary HIV disclosure and negative community reactions, unequal gender relations, difficulties accessing care and treatment, and lack of support from husbands. The whole approach to the delivery of the PMTCT programme and home visits must be reconsidered, to improve confidentiality and minimise stigmatization. Women need to be empowered economically and supported to access HIV treatment and care with their partners, to benefit their whole family.

Women's opinions about routine HIV testing during pregnancy: implications for the opt-out approach

The 1995 United States Public Health Service (USPHS) recommendation regarding HIV testing for pregnant women was revised in 2003 calling for routine HIV testing for pregnant women with patient notification. Routine testing (opt-out screening) offers women the opportunity to decline HIV testing but eliminates the requirement of pretest counseling and separate written consent. To assess women's opinions about the opt-out approach to HIV testing during pregnancy, a cross-sectional survey was conducted in May-June 2004 at 14 geographically diverse clinics funded by Ryan White CARE Act (RWCA) Part C and Part D agreements. Of 853 women respondents to the one-page, self-completed survey questionnaire, 90% agreed with routine HIV testing and 91% reported being comfortable with testing, demonstrating that the large majority of women agree with and support HIV testing as a part of routine prenatal care. Women's opinions were associated with HIV testing status, e.g., 76% of women who had never been tested for HIV thought HIV testing should be part of a routine pregnancy check-up as compared with women who were HIV-negative (93%) or HIV-positive (90%) (chi(2) = 31.3943, p < 0.0001). Comfort with HIV testing was associated with higher HIV knowledge. Approximately half of the respondents indicated that HIV tests are different from other tests and that women need more information prior to testing. Results demonstrated clear consensus in support of routine testing. Increased efforts to disseminate resources to providers coupled with providers' effective communication of information to pregnant women can build on the support that women have conveyed for HIV testing during pregnancy.

HIV testing among pregnant women in Brazil: rates and predictors

OBJECTIVE

To assess rates of offering and uptake of HIV testing and their predictors among women who attended prenatal care.

METHODS

A population-based cross-sectional study was conducted among postpartum women (N=2,234) who attended at least one prenatal care visit in 12 cities. Independent and probabilistic samples were selected in the cities studied. Sociodemographic data, information about prenatal care and access to HIV prevention interventions during the current pregnancy were collected. Bivariate and multivariate analyses were carried out to assess independent effects of the covariates on offering and uptake of HIV testing. Data collection took place between November 1999 and April 2000.

RESULTS

Overall, 77.5% of the women reported undergoing HIV testing during the current pregnancy. Offering of HIV testing was positively associated with: previous knowledge about prevention of mother-to-child transmission of HIV; higher number of prenatal care visits; higher level of education and being white. HIV testing acceptance rate was 92.5%.

CONCLUSIONS

The study results indicate that dissemination of information about prevention of mother-to-child transmission among women may contribute to increasing HIV testing coverage during pregnancy. Non-white women with lower level of education should be prioritized. Strategies to increase attendance of vulnerable women to prenatal care and to raise awareness among health care workers are of utmost importance.

Prevalence and predictors of failure to return for HIV-1 post-test counseling in the era of antiretroviral therapy in rural Kilimanjaro, Tanzania: challenges and opportunities

In this era of antiretroviral therapy (ART) a limited number of population-based studies have investigated the extent of voluntary counseling and testing acceptance and completion in Africa. The aim of this study was to assess the prevalence and predictors of failure to return for HIV post-test counseling (PTC) among adults in rural Kilimanjaro, Tanzania. Following a cross-sectional survey, people aged 15-44 years living in Oria village were interviewed and offered individual HIV-1 pre-test counseling. They were asked to return for PTC two weeks after blood sample collection. HIV-1 testing was accepted by 1491 (97.6%) of participants with 98.9% expressing desire to know their results. The proportion of individuals who did not return for PTC was 50.9%. These proportions did not differ by sex. Seropositive HIV result (AOR: 2.2; 95%CI: 1.3-4.3 for women and AOR: 2.1, 95%CI: 1.2-5.7 for men), low HIV/AIDS-transmission and ART availability knowledge, perceived low risk of HIV infection, not accepting to share results (men only) and inability to self-prevent HIV infection (women only) predicted failure to return for PTC. Additionally, participants were more likely not to return for PTC if they had no-formal education or reported recent sexual-risk behaviors, for both sexes. Age, prior HIV testing or AIDS-related clinical symptoms were not associated with return for PTC in this population. These findings suggest that low returns for PTC, especially for HIV-seropositive individuals, result in a substantial missed opportunity for prevention and care. Knowledge of ART accessibility is necessary but not sufficient to promote adequate return for PTC. The high attendance for pre-test counseling should be utilized to identify potential individuals who may not return for PTC and to promote risk reduction and care.

Perinatal HIV transmission and the cost-effectiveness of screening at 14 weeks gestation, at the onset of labour and the rapid testing of infants

BACKGROUND

Preventing HIV transmission is a worldwide public health issue. Vertical transmission of HIV from a mother can be prevented with diagnosis and treatment, but screening incurs cost. The U.S. Virgin Islands follows the mainland policy on antenatal screening for HIV even though HIV prevalence is higher and rates of antenatal care are lower. This leads to many cases of vertically transmitted HIV. A better policy is required for the U.S. Virgin Islands.

METHODS

The objective of this research was to estimate the cost-effectiveness of relevant HIV screening strategies for the antenatal population in the U.S. Virgin Islands. An economic model was used to evaluate the incremental costs and incremental health benefits of nine different combinations of perinatal HIV screening strategies as compared to existing practice from a societal perspective. Three opportunities for screening were considered in isolation and in combination: by 14 weeks gestation, at the onset of labor, or of the infant after birth. The main outcome measure was the cost per life year gained (LYG).

RESULTS

Results indicate that all strategies would produce benefits and save costs. Universal screening by 14 weeks gestation and screening the infant after birth is the recommended strategy, with cost savings of $1,122,787 and health benefits of 310 LYG. Limitations include the limited research on the variations in screening acceptance of screening based on specimen sample, race and economic status. The benefits of screening after 14 weeks gestation but before the onset of labor were also not addressed.

CONCLUSION

This study highlights the benefits of offering screening at different opportunities and repeat screening and raises the question of generalizing these results to other countries with similar characteristics.

Prenatal HIV testing in the US-Mexico border region, 2005: the Brownsville-Matamoros Sister City Project for Women's Health

INTRODUCTION

Routine prenatal human immunodeficiency virus (HIV) screening provides a critical opportunity to diagnose HIV infection, begin chronic care, and prevent mother-to-child transmission. However, little is known about the prevalence of prenatal HIV testing in the US-Mexico border region. We explored the correlation between prenatal HIV testing and sociodemographic, health behavior, and health exposure characteristics.

METHODS

The study sample consisted of women who delivered live infants in 2005 in hospitals with more than 100 deliveries per year and resided in Matamoros, Tamaulipas, Mexico (n = 489), or Cameron County, Texas (n = 458). We examined univariate and bivariate distributions of HIV testing in Matamoros and Cameron County and quantified the difference in odds of HIV testing by using logistic regression.

RESULTS

The prevalence of prenatal HIV testing varied by place of residence--57.6% in Matamoros and 94.8% in Cameron County. Women in Cameron County were significantly more likely than those in Matamoros to be tested. Marital status, education, knowledge of methods to prevent HIV transmission (adult-to-adult), discussion of HIV screening with a health care professional during prenatal care, and previous HIV testing were significantly associated with prenatal HIV testing in Matamoros, although only the latter 2 variables were significant in Cameron County.

CONCLUSION

Although national policies in both the United States and Mexico recommend prenatal testing for HIV, a greater proportion of women in Cameron County were tested, compared with women in Matamoros. Efforts between Matamoros and Cameron County to improve HIV testing during pregnancy in the border region should consider correlates for testing in each community.

Experiences of women in obtaining human immunodeficiency virus testing and healthcare services

PURPOSE

Over a decade ago, the U.S. Public Health Service recommended routine human immunodeficiency virus (HIV) testing for pregnant women. Despite this recommendation, nearly 30% of pregnant women report not being tested. The purpose of this qualitative study was to describe personal experiences of women in obtaining HIV testing and healthcare services in east Texas.

DATA SOURCES

A secondary data analysis was conducted using audiotapes and transcriptions from structured group interview data obtained from HIV-positive and high-risk negative women residing in east Texas (n = 64).

CONCLUSIONS

Content analysis revealed three patterns: living with stigma; struggling to be healthy; and getting along, day by day. Additional findings indicated that women are more likely to access HIV testing if they are assured of confidentiality and women living with HIV are more likely to remain in the healthcare system if healthcare professionals are supportive, knowledgeable, and nonjudgmental.

IMPLICATIONS FOR PRACTICE

Healthcare professionals must engage in self-reflection to conscientiously uncover their true feelings related to caring for women with or at risk for HIV disease. Once providers acknowledge that their beliefs and values differ from their clients, they will be able to minimize personal biases that interfere with HIV testing and healthcare services.

Screening HIV in pregnancy: a survey of prenatal care patients

BACKGROUND

Women in Canada, as in the rest of the world, represent an increasing proportion of new HIV positive cases. In 2002, women accounted for 25% of all positive HIV tests reported in Canada; with the majority being in their childbearing years (15 to 39 years), perinatal transmission of HIV in Canada is cause for concern. Following the development of interventions that can effectively reduce vertical transmission rate, prenatal screening of HIV has become the first and most pivotal step in the prevention of mother-to-child HIV transmission. The purpose of this study was to assess how women's knowledge and attitudes regarding HIV and HIV screening in pregnancy influence screening rates.

METHOD

A prospective anonymous survey of 231 women attending antenatal care clinics at a teaching university hospital or in a community clinic was conducted.

RESULTS

In general, pregnant women supported universal HIV screening in the prenatal period. Women who previously had been tested for HIV and who did not perceive that they were at risk for contracting HIV were more likely to decline HIV testing in their current pregnancy. Overall knowledge regarding HIV and its transmission is less than optimal, particularly among those women who declined HIV testing.

CONCLUSION

Knowledge gaps exist between women accepting and declining prenatal HIV screening, particularly relating to benefits of screening. These results suggest that efforts have to continue to be put into educating the public but also, importantly, into changing current attitudes.

Missed opportunities for participation in prevention of mother to child transmission programmes: simplicity of nevirapine does not necessarily lead to optimal uptake, a qualitative study

BACKGROUND

The objective of this study was to examine missed opportunities for participation in a prevention of mother-to-child transmission (PMTCT) programme in three sites in South Africa. A rapid anthropological assessment was used to collect in-depth data from 58 HIV-positive women who were enrolled in a larger cohort study to assess mother-to-child HIV transmission. Semi-structured interviews were conducted with the women in order to gain an understanding of their experiences of antenatal care and to identify missed opportunities for participation in PMTCT.

RESULTS

15 women actually missed their nevirapine not because of stigma and ignorance but because of health systems failures. Six were not tested for HIV during antenatal care. Two were tested but did not receive their results. Seven were tested and received their results, but did not receive nevirapine. Health Systems failure for these programme leakages ranged from non-availability of counselors, supplies such as HIV test kits, consent forms, health staff giving the women incorrect instructions about when to take the tablet and health staff not supplying the women with the tablet to take.

CONCLUSION

HIV testing enables access to PMTCT interventions and should therefore be strengthened. The single dose nevirapine regimen is simple to implement but the all or nothing nature of the regimen may result in many missed opportunities. A short course dual or triple drug regimen could increase the effectiveness of PMTCT programmes.

HIV testing in a national sample of pregnant US women: Who is not getting tested?

It is recommended that all pregnant women in the US receive an HIV test as early as possible during prenatal care to allow HIV-infected women to begin receiving anti-retroviral drugs when they most effectively prevent transmission. We analyzed interview data from a nationally-representative sample of pregnant women to examine the extent of HIV testing among pregnant women and the characteristics associated with testing, including access to healthcare. We used data from the combined 2001 and 2002 Behavioral Risk Factor Surveillance System, a nationally-representative telephone-based behavioral survey of adults, aggregated across all states to yield national estimates. Among 4,855 women pregnant at interview we looked at the percentages recently tested and never tested by major populations subgroups and assessed differences using chi-square tests and multiple logistic regression analysis. Pregnant women were tested at a much higher rate than other women of the same age - 54.1% had been tested in the past year compared with 15.4% of non-pregnant women. Categories of pregnant women that were more likely to never have been tested for HIV include those without a health plan or insurance (adjusted odds ratio (AOR): 1.6) and those without a personal doctor (AOR: 1.7). Women with knowledge of methods to prevent perinatal HIV transmission were less likely to have never been tested (AOR: 0.8). Attaining the recommended goal of universal prenatal testing will require attention to women without personal doctors or health insurance.

Detecting Unsuspected HIV Infection With a Rapid Whole-Blood HIV Test in an Urban Emergency Department

OBJECTIVE

To evaluate and compare HIV screening and provider-referred diagnostic testing as strategies for detecting undiagnosed HIV infection in an urban emergency department (ED).

METHODS

From January 2003 through April 2004, study staff offered HIV screening with rapid tests to ED patients regardless of risks or symptoms. ED providers could also refer patients for diagnostic testing. Patients aged 18 to 54 years without known HIV infection were eligible.

RESULTS

Of 4849 eligible patients approached for screening, 2824 (58%) accepted and were tested; 414 (95%) of 436 provider-referred patients accepted and were tested. Thirty-five (1.2%) screened patients and 48 (11.6%) provider-referred patients were infected with HIV (P < 0.001). Of these, 18 (51%) screened patients and 24 (50%) referred patients reported no traditional risk factors; 27 (77%) screened patients and 38 (79%) referred patients entered HIV care. Of HIV-infected patients with CD4 cell counts available, 14 (45%) of 31 screened patients and 37 (82%) of 45 provider-referred patients had <200 cells/microL (P < 0.001).

CONCLUSIONS

ED screening detects HIV infection and links to care patients who may not be tested through risk- or symptom-based strategies. The diagnostic yield was higher among provider-referred patients, but screening detected patients earlier in the course of disease.

Predictors of failure to return for HIV test results among pregnant women in Moshi, Tanzania

Identification of HIV-infected women is a prerequisite in HIV perinatal prevention programs. The aim of this study was to determine the predictors of failure to return for HIV posttest results among pregnant women (N=2654) receiving antenatal care at primary health clinics in Moshi urban district, Tanzania. Consenting pregnant women, who were in the third trimester of pregnancy, received individual pretest counseling, followed by interview and screening for HIV. Posttest counseling and results were given after 1 week. A total of 182 (7%) failed to return for their HIV test results. Women were less likely to return for test results if their partners did not come for testing (adjusted odds ratio [AOR], 12.6; 95% CI, 3.1-51.4), if their partners consumed alcohol (AOR, 1.8; 95% CI, 1.3-2.7), and if they had never discussed reproductive health matters with their partners (AOR, 1.7; 95% CI, 1.1-2.7). Additionally, the site of recruitment, age, alcohol consumption, and advanced gestation age predicted failure to return for HIV test results. These results indicate that male partner factors were important in determining whether women returned for results. We therefore recommend promotion of antenatal couple counseling and strengthening of community awareness of the availability of perinatal interventions, with special efforts targeting men. Furthermore, the predictors for failure to collect test-results need to be addressed during pretest counseling.

Mexican women's reasons for accepting or declining HIV antibody testing in pregnancy

OBJECTIVE

To determine pregnant women's reasons for accepting or declining the HIV test in Leon, Mexico.

DESIGN

A cross-sectional study using a face-to-face questionnaire.

SETTING

The antenatal clinic at a tertiary-care referral hospital in Leon, Mexico.

PARTICIPANTS

1184 pregnant women.

DATA COLLECTION

Reasons for accepting or declining the HIV antibodies test, socio-economic characteristics and risk factors for HIV were recorded. Blood samples were obtained from women who accepted to be tested, and positive serologies to HIV on duplicate enzyme-linked immunosorbent assay testing were confirmed by Western Blot assay.

FINDINGS

1009 (85.2%) women accepted the HIV antibodies test. The main reason for accepting it was that women felt the test could be beneficial to their babies (45.1%). The two main reasons for rejecting the HIV antibodies test were that women felt the test was unnecessary because their husbands did not have sexual intercourse with other women (32.6%), and because they did not have permission from their husbands for accepting the test (23.5%). None of the women tested positive for HIV antibodies (0 per 1009).

KEY CONCLUSIONS

The reasons for accepting the HIV test were similar to those reported in developed countries. One important reason for declining the test was that women did not have their husband's permission.

IMPLICATIONS FOR PRACTICE

The acceptance rate for HIV testing in pregnant women could be improved by counselling men on the value of their wives being tested in pregnancy.

HIV Testing Among U.S. Women During Prenatal Care: Findings from the 2002 National Survey of Family Growth

OBJECTIVES

To measure progress toward the US Public Health Service recommended goal that HIV screening be part of the routine battery of prenatal tests for all pregnant women, using data from a nationally-representative reproductive health survey.

METHODS

Data from the 2002 National Survey of Family Growth (NSFG) measure self-reported prenatal HIV testing for all women who had a completed pregnancy in the 12 months before interview. We estimated the percentage with a prenatal test for categories defined by major socio-economic groups, HIV risk, knowledge of HIV treatment, and access to health care.

RESULTS

Sixty-nine percent of 748 recently pregnant women reported receiving a prenatal HIV test. The percentage tested was significantly higher for women with incomes below 300% of the poverty level (76%) and women who reported some degree of HIV risk (82%), suggesting that prenatal care providers offer and encourage testing based on perceived risk, even though universal HIV screening is recommended. Testing was also higher among women with knowledge of interventions to prevent perinatal HIV transmission (74%), suggesting that more public information on these treatments might be helpful.

CONCLUSIONS

A national estimate indicates that nearly one in 3 recently pregnant women reported they were not tested for HIV during prenatal care. Studies showing that prenatal testing for other infectious diseases can approach 100% suggest that a similar level of testing is attainable for perinatal HIV screening, particularly if it is incorporated into the routine package of prenatal tests and procedures offered to all pregnant women.

Disparities in prenatal HIV testing: evidence for improving implementation of CDC screening guidelines

OBJECTIVES

We investigated the within-group and between-group variation in prenatal HIV testing in a sample of low-income pregnant and recently postpartum women.

METHODS

Multivariable linear regression was used to estimate proportional differences in prenatal HIV testing for the total sample and stratified by race.

RESULTS

In bivariate analyses, race and site of care jointly affected the probability of being tested. Hispanic women had the highest probability of being tested in public practice settings but relative to white women, black women had a higher probability of being tested in public and private practice settings. Predictors of prenatal HIV testing differed by race. Receiving prenatal care in a community health center or hospital outpatient clinic increased the probability of testing for Hispanics. Being a recent victim of intimate partner violence was associated with less frequent testing for blacks. Positive beliefs about HIV screening, while significant for blacks and Hispanics, was the only factor associated with testing for whites.

CONCLUSION

Our data suggest that racial biases may be influencing providers' approach to testing, rather than CDC's 2001 guidelines for HIV screening of pregnant women. Study findings are being used to modify social marketing campaigns and improve provider trainings regarding prenatal HIV testing.

Achieving universal HIV screening in prenatal care in the United States: provider persistence pays off

Routine voluntary HIV testing with the right to decline (the "opt-out" approach) is recommended for all pregnant women in the United States but not all are tested. We examined data from surveys of prenatal care providers to identify factors associated with universal testing among patients. Data are from a probability survey conducted in 1999 with prenatal care providers in four separate areas. Survey participants completed a self-administered questionnaire. We computed the percentage of providers reporting universal testing by characteristics of the provider's practice, medical specialty, how strongly they encouraged testing, perceptions of patients' risk, and whether they saw patients in public clinics. In the four locations (Brooklyn, New York; North Carolina; Connecticut; and Dade County, Florida) 95%-99% of providers reported that they routinely offered HIV testing to all pregnant women; the average percentage tested was 64%-89%. The percentage reporting that all of their patients were tested ranged from 12%-62%. The percent of providers reporting universal testing was positively associated with the degree to which testing was encouraged, particularly encouragement to women perceived to be low risk. In some areas, universal testing varied by medical profession, with obstetric physicians and residents, and nurse-midwives reporting a lower percentage of universal testing than family practice physicians and residents. To achieve the goal of routine HIV testing of all pregnant women, education and training must be delivered to all prenatal care providers. This training should emphasize the importance of routine testing. Even with the opt-out approach, many women may decline testing if their doctor does not recommend and encourage HIV testing.

Predictors of HIV testing and intention to test among Hispanic farmworkers in South Florida

CONTEXT AND PURPOSE

This study examined the predictors of HIV testing and factors associated with intention to accept a free HIV test among 244 Hispanic migrant/seasonal farmworkers in South Florida.

METHODS

Time and space sampling procedures were used to recruit participants in public venues. Bilingual staff interviewed eligible respondents in these settings.

FINDINGS

Despite high rates of sexual risk, only 21% of respondents had been tested for HIV. The majority of those tested were females tested during prenatal care. In multivariable logistic regression analyses, being female (odds ratio [OR] = 3.73), having at least 12 years of education (OR = 4.46), earning more than $201 per week (OR = 2.76), and ever having used marijuana (OR = 3.31) were positively associated with having been tested for HIV, while not being documented (OR = 0.24) and having rated one's health as "very good" or "good" (OR = 0.42) were negatively associated with testing. The multivariable predictors of intention to accept a free HIV test were having visited a health care provider and/or an emergency room in the past 12 months (OR = 1.97), having been tested for HIV (OR = 2.36), preferring an HIV test that used a finger stick for specimen collection with results given in 30 minutes (OR = 4.47), and worrying "some" or "a lot" about getting HIV (OR = 3.64). Women (OR = 0.52) were less likely than men to intend to accept a free HIV test.

CONCLUSIONS

Our findings highlight the importance of routinely offering HIV testing to sexually active individuals in high HIV prevalence areas. They also suggest the need to make testing more accessible to migrant and seasonal farmworkers.

Unique challenges to preventing perinatal HIV transmission among Hispanic women in California: results of a needs assessment

To identify rates and factors associated with timely prenatal care (PNC) initiation, HIV test counseling, test offering, and test offer acceptance, we conducted a semistructured survey of a convenience sample of pregnant/recently delivered Hispanic women (n=453, 418 with analyzable data) in four California counties in 2000. Only 68.4% and 43.5% of Hispanic women reported receiving an HIV test offer and counseling, respectively, though 88.8% of those offered a test accepted. After controlling for the effects of age, education, years lived in the United States, health insurance coverage, delivery status, and parity, Hispanic women who initiated prenatal care in the first trimester were 1.7 times more likely to be offered an HIV test and almost 3 times more likely to receive counseling than women with a later prenatal care start or no prenatal care. Factors associated with timely PNC initiation on multivariate analysis were private/HMO insurance (OR=10.7, p < .001), Medi-Cal insurance (OR = 4.32, p < .001), being 25-30 years old (OR = 3.0, p = .008), and completion of high school (OR = 2.07, p = .01). Key opportunities to prevent perinatal HIV transmission are being lost for Hispanic women in California. Interventions to increase timely PNC initiation, and to improve test offering by health care providers, may help to improve counseling and testing rates for this population.

Women's knowledge about treatment to prevent mother-to-child human immunodeficiency virus transmission

OBJECTIVE

To provide national estimates of knowledge about treatments available to reduce mother-to-infant human immunodeficiency virus (HIV) transmission among U.S. women of childbearing age.

METHODS

We used data from 55712 women aged 18 to 44 years who responded to questions on antiretroviral treatment in the 2001 Behavioral Risk Factor Surveillance System. We obtained the percentage of women who correctly answered a question on treatment to prevent mother-to-child transmission of HIV and determined factors independently associated with such knowledge using a multiple logistic regression model.

RESULTS

Overall, the percentage of women who correctly stated that treatment existed to help prevent mother-to-child transmission of HIV was 58.6% (95% confidence interval 57.9, 59.3). In the multiple logistic regression model that controlled for sociodemographics, having correct knowledge about treatment to prevent mother-to-child HIV transmission was independently associated with being black, younger age (18-34 years), college level education, and having been tested for HIV. Current pregnancy was not an independent predictor of having knowledge about the availability of treatment to prevent mother-to-child transmission.

CONCLUSION

Among US women of childbearing age, just over one half had correct knowledge of effective perinatal HIV prevention strategies. Increasing the awareness of these treatments may lead to greater uptake of HIV testing among pregnant women.

Prenatal testing for infectious disease

Prenatal testing for infectious diseases is performed frequently and for a variety of indications. The purpose of this article is to review the maternal and fetal infections that pose diagnostic concerns. Recent advances in diagnostic testing (such as avidity testing) is included. Testing issues focus on the diagnosis of maternal and fetal infection.

Prenatal HIV counseling and testing in California: women's experiences and providers' practices

Two concurrent surveys were conducted in four California counties to compare the prenatal HIV counseling and voluntary testing (C&VT) experiences of women with the self-reported practices of prenatal care providers. Participants were 850 women currently or recently receiving prenatal care and 254 providers. Although 79.9% of women reported being offered an HIV test during a prenatal visit, only 56.2% said they were told about the risks and benefits of taking an HIV test. Almost all providers (98.4%) indicated they offer an HIV test, and 76.8% reported offering counseling, to every patient. One third of the women (65.9%) knew that treatment exists for reducing the chance of prenatal transmission of HIV, and 78.7% of women said they were more likely to be tested given knowledge of such therapy. Women may have underreported prenatal C&VT because providers spend insufficient time discussing related issues or because C&VT information is not presented in a way that is relevant to all patients.

To test or not to test: are Hispanic men at highest risk for HIV getting tested?

This study examined how HIV testing history and future testing intentions were related to sexual risk and perceptions of risk in a community sample of 1,052 Hispanic men. This sample is noteworthy in its diverse representation of Hispanics, its high ratio of participants born outside the USA, and its inclusion of heterosexuals and men who have sex with men (MSM). We used area-based sampling to recruit participants at public venues. Data were collected via anonymous, structured interviews from December 1999 to February 2001. Lifetime testing rates were high (76%), but only 45% had been tested in the last 12 months. Results indicate that men at highest risk-those who were MSM, had more partners and had STDs-were more likely to have been tested, and to have been tested recently, than men with lower risk. Being MSM and having been previously tested predicted future testing intentions. Inconsistent condom users with more than five partners were less likely to intend to be tested than men with more than five partners who used condoms consistently. Studying men who have successfully routinized HIV prevention practices (including testing) will assist in the development of interventions for those who remain at risk.

Violence during pregnancy among women with or at risk for HIV infection

OBJECTIVES

This study estimated the prevalence of violence during pregnancy in relation to HIV infection.

METHODS

Violence, current partnerships, and HIV risk behaviors were assessed among 336 HIV-seropositive and 298 HIV-seronegative at-risk pregnant women.

RESULTS

Overall, 8.9% of women experienced recent violence; 21.5% currently had abusive partners. Violence was experienced by women in all partnership categories (range = 3.8% with nonabusive partners to 53.6% with physically abusive partners). Neither experiencing violence nor having an abusive partner differed by serostatus. Receiving an HIV diagnosis prenatally did not increase risk. Disclosure-related violence occurred, but was rare.

CONCLUSIONS

Many HIV-infected pregnant women experience violence, but it is not typically attributable to their serostatus. Prenatal services should incorporate screening and counseling for all women at risk for violence.
