Barriers to universal prenatal HIV testing in 4 US locations in 1997

Innovation and implementation determinants of HIV testing and linkage-to-care in the U.S.: a systematic review

OBJECTIVE

To identify innovation and implementation determinants of HIV testing, diagnosis, and linkage-to-care in the U.S.

DATA SOURCES AND STUDY SETTING

Between November 2020 and January 2022, a broad search strategy was employed in three literature databases: Ovid MEDLINE, PsycINFO, and Web of Science.

STUDY DESIGN

A systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement.

DATA COLLECTION/EXTRACTION METHODS

A team of master's and Ph.D.-level researchers screened eligible studies against the inclusion criteria and extracted the data using COVIDENCE software in pairs with consensus performed by a senior member of the team. Barriers and facilitators were extracted and analyzed according to the Consolidated Framework for Implementation Research (CFIR). Frequency of determinants across studies was mapped according to CFIR, valence, study design, delivery setting, unit of analysis, population of interest, region of the U.S., and year.

RESULTS

We identified 1,739 implementation and innovation determinants from 186 articles. Most determinants were for HIV testing rather than linkage-to-care. Most determinants were identified in the inner setting and individuals domains of CFIR, with the fewest identified in the process and innovations domains. Determinants of providers were only slightly more frequently identified than determinants of recipients. However, determinants of organizations and systems were rarely identified.

CONCLUSION

This review provides a synthesis of innovation and implementation determinants of HIV testing and linkage-to-care using the most-cited implementation science (IS) framework, CFIR. This synthesis enables the larger field of HIV science to utilize IS in efforts to end the HIV epidemic and positions IS to consider the application of IS frameworks to fields like HIV.

Uptake and determinants for HIV postpartum re-testing among mothers with prenatal negative status in Njombe region, Tanzania

Background

Uptake of Human Immunodeficiency Virus (HIV) re-testing among postnatal mothers who had previously tested HIV-negative is crucial for the detection of recent seroconverters who are likely to have high plasma viral loads and an increased risk of mother-to-child HIV transmission. Tanzania set a target of 90% re-testing of pregnant mothers who had tested negative during the first test. However, there is no statistics on the implementation, coverage and the factors determining re-testing among pregnant women in Tanzania. This study determined the proportion of newly-delivered, previously HIV-negative mothers who returned for HIV re-testing, and assessed the determinants of re-testing in Njombe Region in Tanzania.

Methods

A cross-sectional study was conducted in four health facilities in Njombe and Wanging’ombe districts during December 2015–June 2016. All newly-delivered mothers (≤7 days from delivery) presenting at health facilities and who had previously tested HIV-negative during pregnancy were included. A structured questionnaire was used to collect data on the determinants for re-testing. Records on the previous HIV testing was verified using antenatal clinic card. A multiple logistic regression model was used to calculate the adjusted odds ratio (AOR) with their 95% confidence intervals (CI) to quantify the association.

Results

Of 668 mothers (median age = 25 years) enrolled, 203 (30.4%) were re-tested for their HIV status. Among these, 27 (13.3%) tested positive. Significant predictors for HIV re-testing were socio-demographic factors including having at least a secondary education [AOR = 1.9, 95% CI: 1.25–3.02] and being employed [AOR = 2.1, 95% CI: 1.06–4.34]; personal and behavioural factors, reporting symptoms of sexually transmitted infections [AOR = 4.9, 95% CI: 2.15–6.14] and use of condoms during intercourse [AOR = 1.7, 95% CI: 1.13–2.71]. Significant health system factors were having ≥4 ANC visits [AOR = 1.8, 95% CI: 1.21–2.69] and perceiving good quality of HIV counselling and testing service at the first ANC visit [AOR = 2.14, 95% CI: 1.53–3.04].

Conclusion

Uptake of the HIV re-testing was lower than the national target. Education level, employment status, having ≥4 ANC visits, reporting sexually-transmitted infections, condom use, and good perception of HIV tests were significant factors increased uptake for re-testing. Identified factors should be incorporated in the Prevention of the Mother-to-Child Transmission (PMTCT) programme strategies to prevent HIV infection in new-borns.

Contemporary management of human immunodeficiency virus in pregnancy

Contemporary management of HIV in pregnancy remains a moving target. With the development of newer antiretroviral agents with lower side-effect profiles and laboratory methods for detection and monitoring of HIV, considerable progress has been made. This review examines key concepts in the pathophysiology of HIV and pregnancy with emphasis on perinatal transmission and reviews appropriate screening and diagnostic testing for HIV during pregnancy. Current recommendations for medical, pharmacologic, and obstetric management of women newly diagnosed with HIV during pregnancy and for those women with preexisting infection are discussed. Preconception counseling for HIV+ women as well as postpartum issues are addressed.

HIV status determination among tuberculosis patients from California during 2008

CONTEXT

Human immunodeficiency virus (HIV) infection complicates care and contributes to poor outcomes among tuberculosis (TB) patients. The Centers for Disease Control and Prevention recommends that providers test all TB patients for HIV.

OBJECTIVE

We assessed completeness of HIV status determination among TB patients and identified key gaps in adherence.

DESIGN

We conducted a retrospective review of public health charts to determine the HIV status for all TB patients reported in California during 2008. We then used logistic regression to determine the factors associated with a known (positive or negative) HIV status. A random sample of TB patients was selected for secondary review to characterize the timing of HIV status determination and the providers who had opportunity to test for HIV.

SETTING

California TB programs.

PARTICIPANTS

All TB patients reported from California in 2008.

MAIN OUTCOME MEASURES

Proportion of patients with a known HIV status, adjusted odds ratios for having a known HIV status, proportion of patients with a known HIV status before TB diagnosis, and proportion of patients diagnosed with TB by different provider types.

RESULTS

Only 1752 (66%) of 2667 TB patients had a known HIV status. Having a known HIV status was strongly associated with those aged between 15 and 44 years and being managed with any public provider involvement. Of 292 patients in the random sample, 12 patients (4%) had a known HIV status before TB diagnosis. Among the remaining 280 patients, 187 patients (67%) were diagnosed with TB by a private provider.

CONCLUSIONS

The HIV status determination of TB patients was selective and not routine as recommended. Private providers can play a key role in testing for HIV at TB diagnosis. California TB programs should ensure that all TB patients have an HIV status by promulgating national recommendations, educating private providers on the benefits of testing TB patients for HIV, and monitoring completeness of HIV status determination.

Routine prenatal HIV testing: women's concerns and their strategies for addressing concerns

The purpose of this exploratory study was to solicit women’s opinions about the process of routine prenatal HIV testing to identify strategies for routine testing that will address women’s concerns, increase their level of comfort with testing, and support universal prenatal HIV testing. A convenience sample of English-speaking women between 18 and 45 years of age who were HIV-negative or of unknown HIV status were recruited for focus groups at four diverse community sites in four states. Focus group discussion questions addressed health care provider approaches and actions that would make a woman feel more comfortable with the process of routine prenatal HIV testing. Twenty-five women agreed to participate; most women (64%) were of Black, non-Hispanic race/ethnicity; 44% were 25–34 years of age. Thematic analysis of women’s concerns about routine prenatal HIV testing fell into the following categories: fear, protecting the baby, protecting the woman, confidentiality, and stigma. Women’s strategies for addressing these concerns were related to themes of education and information, normalizing HIV testing, patient–provider relationships, systems, and private communication. Participants offered numerous insightful and practical suggestions for addressing their concerns thereby supporting universal routine prenatal HIV testing. The themes that arose in this study support the conclusion that women will be more comfortable with routine prenatal HIV testing if they are fully informed and knowledgeable about the rationale for HIV testing during pregnancy and their right to decline, and if testing is carried out in a confidential and supportive health care environment.

Universal prenatal HIV screening: are we there yet?

The objectives of this study were to determine the prevalence of and factors associated with prenatal HIV screening and the availability of HIV test results in medical records in Pittsburgh, PA, USA. Three hundred postpartum women were surveyed about demographics and prenatal care provider(s) and practice setting and were asked to recall prenatal HIV screening and reasons for accepting or declining a HIV test. Medical records were reviewed for documentation of HIV results. Overall, 65% of women reported screening. White race, higher annual household income and fewer lifetime sexual partners were independently associated with decreased likelihood of prenatal HIV screening. Provider presentation of screening as standard practice and provider encouragement were associated with prenatal HIV screening. Only 38% of medical records contained HIV results at the time of labour. Universal and routine offering of prenatal HIV screening as standard practice, in conjunction with encouragement from health-care providers, may increase patient acceptability and the uptake of prenatal HIV screening.

Factors associated with declining a rapid human immunodeficiency virus test in labor and delivery

The Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists recommend routine rapid HIV testing in labor and delivery (L&D) for women with undocumented HIV status using an opt-out approach. Identifying factors associated with declining a rapid HIV test in L&D will be helpful in developing strategies to improve rapid HIV testing uptake. Data from the Mother-Infant Rapid Intervention at Delivery study were analyzed. Women ≥24 weeks gestation, in labor, with undocumented HIV status were offered rapid HIV testing using informed consent. Women who declined rapid HIV testing (decliners) but agreed to be interviewed were compared to women who accepted testing (acceptors). 102 decliners and 478 acceptors met inclusion criteria for analysis. Decliners of rapid HIV testing were more likely to have had prenatal care (PNC), after adjusting for age, Hispanic ethnicity, high-school education and city of enrollment (adjusted OR 2.4, 95% CI 1.06-5.58). Having had PNC was collinear with prior HIV education and previous offer of an HIV test during the current pregnancy, so these factors were not part of the model. During PNC, standard informed consent may involve discussions that negatively affect later uptake of testing in L&D. Therefore an opt-out approach to testing may improve testing rates. Furthermore, decliners may have felt that testing in L&D was redundant because of previous testing during PNC; however, if previous testing occurred, this was undocumented at L&D. Documentation and timely communication of HIV status is critical to provide appropriate HIV prophylaxis.

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 feasibility of using an 'opt-out' approach to achieve universal HIV testing of tuberculosis patients in Alberta

OBJECTIVE

Universal HIV testing of tuberculosis (TB) patients, defined as testing greater than 80% of incident cases, has been recommended but not achieved in Canada. The objectives of this study were: i) to assess the success of an 'opt-out' approach, whereby HIV testing is routine unless the patient specifically chooses otherwise, and ii) to determine the risk factors for HIV in patients tested before and after this approach was implemented.

METHODS

TB and HIV databases in the province of Alberta were cross-matched before HAART (highly active anti-retroviral therapy) was available (1991-1997), after HAART but before 'opt-out' testing was implemented (1998-2002), and after 'opt-out' testing was implemented (2003-2006), and the HIV status of TB patients in each time period was described. The demographic and clinical characteristics of HIV-positive and -negative TB patients aged 15-64 years were compared.

RESULTS

HIV testing of TB patients increased from 11.5% before HAART, to 44.9% after HAART but before 'opt-out' testing, to 81.9% after 'opt-out' testing was implemented. Between 1991 and 2006, 50 TB patients were diagnosed with HIV co-infection, all in the age group 15-64 years. Among TB patients aged 15-64 years who were HIV tested, those testing positive were significantly less likely to be female and to have respiratory TB and significantly more likely to have both respiratory and non-respiratory TB. The prevalence of HIV positivity in HIV-tested TB patients aged 15-64 years was 7.4% in 2003-2006.

CONCLUSION

Universal HIV testing of TB patients is achievable through 'opt-out' HIV testing.

An update on HIV and infant feeding issues in developed and developing countries

The field of mother to child transmission of human-immunodeficiency virus is rapidly evolving. In the United States, prevention focuses on implementation of universal human-immunodeficiency virus testing to assure compliance with recommended treatment regimens and infant-feeding strategies. In most cases, this is the avoidance of all breastfeeding. In developing countries, avoidance of breastfeeding places infants at higher risk of morbidity and mortality. Current World Health Organization recommendations require individualized counseling to determine the best feeding method for each woman.

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.

Factors associated with low early uptake of a national program to prevent mother to child transmission of HIV (PMTCT): results of a survey of mothers and providers, Botswana, 2003

In Francistown, Botswana, approximately 40% of pregnant women are HIV positive. PMTCT has been available since 1999, antiretroviral (ARV) therapy since 2001, and 95% of women have antenatal care (ANC) and deliver in hospital. However, in 2002, only 33% of ANC clients were tested for HIV, and not all women with HIV received services. In 2003, we conducted a survey of 504 pregnant and postpartum women to explore reasons for poor program uptake, and interviewed 82 health providers about PMTCT. Most women (95%) believed that all pregnant women should be tested for HIV. In multivariate analysis, factors associated with having an HIV test included being interviewed at an urban site, having a high PMTCT knowledge score, knowing someone receiving PMTCT or ARV therapy, and having a partner who had been tested for HIV. Neither fear of stigma nor resistance from partners were frequent reasons for refusing an HIV test. Providers of HIV services reported discomfort with their knowledge and skills, and 84% believed HIV testing should be routine. Ensuring adequate knowledge about HIV and PMTCT, creating systems whereby HIV-positive women receiving care can educate and support other women, and making HIV testing routine for pregnant women may improve the uptake of HIV testing.

The necessity of HIV testing in Iranian pregnant women and its ethical considerations

A high number of HIV positive babies are born each year, whereas by highly effective preventive measures, the risk of mother-to-child transmission can be decreased significantly. There are different methods (for example mandatory versus voluntary) for HIV screening in pregnant women, but there are debates on conducting HIV testing by these methods. One of the most important issues in this field is its ethical considerations. Also its limitations cannot be ignored. According to these facts several keywords were searched by search engines such as Web of Sciences, Medline, Google scholar, WHO website. The most relevant and recent articles were chosen. Concerning the importance of vertical transmission of HIV, the role of preventive measures, ethical considerations, and the limitations of HIV screening, we recommend HIV testing offer to every pregnant women at the first clinic visit by providing enough information for patient and considering her autonomy. Also policy makers should provide a guideline for this test according to the pregnant women's autonomy, confidentiality, and dignity.

Correlates of prenatal HIV testing in women with undocumented status at delivery

OBJECTIVE

To determine factors associated with prenatal HIV testing in women who accepted rapid testing at delivery.

METHODS

The mother-infant rapid intervention at delivery (MIRIAD) protocol offered counseling and voluntary HIV testing in six US cities including New York City (NYC). These hospitals are required to document the HIV status of pregnant women or their infants. From January 2002 to January 2005, 653 HIV-negative women were interviewed post-partum.

RESULTS

63% of women reported prior HIV testing during the index pregnancy, although their results were not available at delivery. Multivariate logistic modeling identified receipt of prenatal care and delivery in NYC as being associated with having been offered prenatal HIV testing. In a model restricted to women receiving medical care, emergency department (ED) use and delivery outside of NYC were associated with not having been offered testing. In a model restricted to women who were offered prenatal testing, acceptance was associated with delivery outside of NYC.

CONCLUSIONS

Improved documentation of prenatal test results, expanded prenatal testing in non-traditional settings like EDs, and routine voluntary "opt-out" testing during pregnancy may further reduce perinatal HIV transmission.

Routine antenatal HIV testing: the responses and perceptions of pregnant women and the viability of informed consent. A qualitative study

This qualitative cross-sectional survey, undertaken in the antenatal booking clinics of a hospital in central London, explores pregnant women's responses to routine HIV testing, examines their reasons for declining or accepting the test, and assesses how far their responses fulfil standard criteria for informed consent. Of the 32 women interviewed, only 10 participants were prepared for HIV testing at their booking interview. None of the women viewed themselves as being particularly at risk for HIV infection. The minority (n = 6) of the participants who declined testing differed from those who accepted, by interpreting test acceptance as risky behaviour, privileging the negative outcomes of HIV positivity and expressing an inability to cope with these, should they occur. Troublingly, only a minority of women (n = 9) had a broad understanding of the rationale for the test, and none fulfilled the standard criteria for informed consent. This study suggests that, although routine screening combined with professional recommendation may be successful in increasing uptake, this may be at the cost of eroding informed consent. Protecting third parties (notably fetuses) from a preventable disease may outweigh the moral duty of respecting autonomy, enshrined in Western bioethical tradition. Nevertheless, such a policy should be made transparent, debated in the public domain and negotiated with women seeking antenatal care.

Care and management of the infant of the HIV-1-infected mother

Mother-to-child transmission of the human immunodeficiency virus continues to be a major global health problem. The pediatric HIV-1 epidemic is fueled by HIV-1 infection in women of childbearing age with vertical transmission in utero or at the time of birth. In resource-rich countries, the birth of an infected child is a sentinel health event signaling a chain of missed opportunities and barriers to prevention. Because the fate and ultimate HIV-infection status of the baby is inextricably linked to the infection status of the mother and her general state of well-being, we provide in this review: 1) background and state-of-the-art management guidelines for optimum maternal care; 2) strategies to minimize the risk of vertical transmission of HIV; and 3) recommendations for managing infants born to HIV-infected women. These are discussed under four case scenarios that obstetric and pediatric providers frequently encounter in their practices.

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.

Trends in Prenatal Discussion and HIV Testing, 1996–2001: Pregnancy Risk Assessment Monitoring System

OBJECTIVE

To assess trends in prenatal discussions about HIV testing and prenatal HIV testing during the period 1996-2001.

METHODS

Using data from the Pregnancy Risk Assessment Monitoring System, a population-based postpartum survey of women, we calculated the self-reported prevalences of discussion of prenatal HIV testing and testing. Data were analyzed using SUDAAN; trends were calculated by logistic regression for states having >/=3 years of data.

RESULTS

From 1996 to 2001, significant increases in prenatal discussions about HIV testing were seen in 15 of 17 states. During the period 1996-2001, the prevalence of testing increased significantly in 7 of 8 states. In all states, there was a significant, positive relationship between having a prenatal discussion about testing and having an HIV test (odds ratios ranged from 1.7 to 4.9).

CONCLUSIONS

We found statistically significant increases in discussions and testing from 1996 through 2001, consistent with guidelines emphasizing routine prenatal testing. Health care providers may have a strong influence on women's decisions to be tested. Because current guidelines call for simplified strategies to reduce barriers to universal prenatal HIV screening, trends in prenatal HIV testing should continue to be monitored to assess the impact of these changes.

A comparison of perinatal HIV prevention opportunities for Hispanic and non-Hispanic women in California

Using a semi-structured survey and convenience sample of pregnant/recently delivered Hispanic (n = 453) and non-Hispanic (n = 904) women in four California counties, this study compared rates of timely prenatal care (PNC) initiation, HIV test counseling, test offering, and test acceptance in PNC between Hispanic and non-Hispanic women. Hispanic women were less likely to report timely PNC initiation (69.3% vs. 80.4%, p < .0001), receiving test offer (69.5% vs. 76.7%, p = .002), and ever having been tested (77.3% vs. 87.9%, p < .0001) than non-Hispanic women. Hispanic women were more likely to report not knowing where to go (p = .04) and having no insurance (p < .001), transportation (p = .001), and child care (p = .007) as reasons for late PNC start. Both Hispanic and non-Hispanic women most commonly accepted a test offer for their health/health of their baby; Hispanic women were more likely to accept based on doctor/nurse recommendation (80.1% vs. 62.7%, p < .001). A quarter of Hispanic and non-Hispanic women reported they didn't feel they had a choice or that test was done automatically. Efforts to improve perinatal HIV prevention opportunities for all women in California are required. Furthermore, Hispanic women may have disparities in receipt of prenatal care and HIV test offer that need additional attention.

Promising Strategies for Preventing Perinatal HIV Transmission: Model Programs from Three States

OBJECTIVES

This paper describes and compares three innovative methods for preventing perinatal HIV transmission. Each of these strategies has been developed based on an in-depth assessment of the strengths and weaknesses of existing prevention approaches, and the needs of the populations they serve.

METHODS

Florida expanded an existing outreach program to include women in jails in several high-prevalence counties. Incarcerated women were offered testing for pregnancy and HIV and linked to medical and supportive services. One Connecticut hospital sought to increase prenatal HIV testing rates by requiring HIV test results in the electronic medical records. This program is being expanded to other hospitals throughout the state. Louisiana has implemented a systematic review of perinatal data in order to identify potential programmatic enhancements. This review has led to the perinatal fast track system, designed to quickly identify HIV-infected pregnant women and connect them to care.

RESULTS

Each program demonstrated improvements in indicators related to prevention of perinatal HIV transmission, such as increased utilization of prenatal care, increased prenatal testing rates, and decreases in perinatal HIV transmission.

CONCLUSIONS

These case studies emphasize two key similarities among these programs: the value of collaboration between agencies providing care and services to HIV-infected and high-risk women of childbearing age, and the importance of maximizing opportunities for HIV testing and treatment. These strategies have demonstrated effectiveness in improving health outcomes and reducing perinatal HIV transmission.

Barriers for HIV testing during pregnancy in Southern Brazil

OBJECTIVE

To assess HIV testing rate and determine risk factors for not have been tested during pregnancy.

METHODS

A cross-sectional study was carried out in Porto Alegre, Southern Brazil, from December 2000 to February 2001. Socioeconomic, maternal and healthcare variables were obtained by means of a standardized questionnaire. Crude and adjusted odds ratios and their 95% confidence intervals were obtained in logistic regression models.

RESULTS

A total of 1,642 mothers were interviewed. Of them, 94.3% reported being offered HIV testing before or during pregnancy or during labor; 89 mothers (5.4%) were not tested or did not know if they were tested. Attending fewer than six prenatal visits, being single and younger than 18 years old were relevant barriers preventing HIV testing. There was found a relationship between maternal schooling and the category of prenatal care provider. Having low 22.20 (12.43-39.67) or high 3.38 (1.86-7.68). schooling and being cared in the private sector strongly reduced the likelihood of being HIV tested.

CONCLUSIONS

The Brazilian Health Ministry's recommendation for universal counseling and HIV testing has been successfully implemented in the public sector. In order to improve HIV testing coverage, new strategies need to target women cared in the private sector especially those of low schooling.

A faculty trainer model: increasing knowledge and changing practice to improve perinatal HIV prevention and care

Although routine counseling and HIV testing of pregnant women is recommended, it is not yet universally offered. This paper reports on a project that trained health care providers from 2000 to 2002 using a faculty trainer (or train-the-trainer) model. The goals of the projects were to increase knowledge and change practice, increase HIV counseling and testing in prenatal care, and improve management of HIV in pregnant women. In four jurisdictions of the southeastern United States, 193 health care providers attended faculty trainer workshops using a standardized curriculum. Eighteen providers used the curriculum to train an additional 545 health care providers over 2 years. Participants in both faculty trainer workshops and trainerled seminars reported significant increases in perceived knowledge in all content areas and the intention to change clinical practice. The number of providers who became faculty trainers and then led seminars varied widely among the jurisdictions. Six-month follow-up of faculty trainers, although limited by a 63% response rate, found that over 90% of respondents reported the workshop had a positive impact on their care of women with and at risk for HIV. Our findings indicate the faculty trainer model is an effective way to educate practicing clinicians. Key elements to successful implementation were: ongoing support of faculty trainers by acquired immune deficiency syndrome (AIDS) educators, involvement of local HIV experts as trainers and resource persons, and use of a standardized curriculum based on national guidelines.

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.

HIV testing and the role of individual- and structural-level barriers and facilitators

This study determined the overall prevalence of HIV testing within a community sample of heterosexual men and women at high risk for HIV infection, and analysed the gender-specific individual- and structural-level barriers and facilitators to testing. Data were collected through 1,643 personal interviews conducted in Philadelphia between 1999 and 2000. Overall, 79.4% of participants had ever taken an HIV test; women were significantly more likely to have tested than were men. Among the individual-level factors we examined, very few, including sexual and drug-using risk behaviours, were significantly associated with an increased likelihood of ever being tested for HIV. Structural-level factors were important correlates of HIV testing for both women and men. Results of this study indicate that there are gender-based similarities and differences in the correlates of testing, and that efforts to increase HIV testing must consider how structural factors, including access to health care, may deter or facilitate opportunities for HIV testing. In particular, efforts to improve the uptake of HIV testing by heterosexual men at high risk should focus on improving men's access to, and utilization of, routine health care.

Access to appropriate information on HIV is important in maximizing the acceptance of the antenatal HIV antibody test

The universal HIV antibody testing programme was implemented in Hong Kong in September 2001. A survey on acceptance of the test was conducted in the territory's maternal and child health centres in a two-month period. The response rate was 98.2% and 2,669 valid questionnaires were analysed. Seventy per cent (n=1,825) of the respondents indicated their acceptance of the test. A significant association was noted between clients' acceptance and access to HIV information (adjusted odds ratio (OR)=10.45, 95% confidence interval (CI)=6.33-17.26) by means of posters, pamphlets, videos and group talks. Perceived benefits and health care workers' recommendation were the main reported reasons for acceptance, whereas no or low perceived susceptibility was the main reason for refusal. Acceptance was also positively correlated with level of education (adjusted OR=3.99, 95% CI=2.15-7.43) and HIV knowledge (adjusted OR=3.61, 95% CI=2.19-5.93). A high uptake rate (99.6%) reflects that most had the test done eventually despite some initial uncertainty. It is concluded that access to appropriate HIV information was important to maximize the acceptance of the programme.

Personal history of voluntary HIV counseling and testing (VCT) among adults aged 19-35 years living in peri-urban communities, Chiang Mai, Northern Thailand

This study investigates the self-reported history of HIV voluntary counseling and testing (VCT) among adults, aged 19-35 years, in northern Thailand. Participants were interviewed about their HIV testing history and risk behavior. Overall, 47% of 2251 participants had previously been tested, of whom 64% were tested at government clinics. Of those tested at private clinics, 50% reported not receiving pre- and post-test counseling, compared to 15% of those tested in government clinics. Ten percent of those tested had not received their test results. Among those who had never been previously tested for HIV, 66% believed they were not at risk, although 1.5% (2.7% among men) were HIV infected. Although VCT is widely available and utilized by the population of northern Thailand, substantial numbers of HIV infected persons have not been tested for HIV and among those tested many have not received comprehensive counseling. A Thai government policy enforcing effective counseling to accompany HIV testing is urgently needed.

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.

Evaluating Programs to Prevent Mother-to-Child HIV Transmission in Two Large Bangkok Hospitals, 1999-2001

The 2 largest maternity hospitals in Bangkok implemented comprehensive programs to prevent mother-to-child HIV transmission in 1998. We conducted a cross-sectional survey of post-partum HIV-infected women in 1999 through 2001 to evaluate these programs. Women were given structured interviews at 0 to 3 days, 1 month, and 2 months postpartum. Medical records of women and their newborns were reviewed. Of 488 enrolled women, 443 (91%) had antenatal care: 391 (88%) at study hospitals and 52 (12%) elsewhere. The HIV diagnosis was first known before pregnancy for 61 (13%) women, during pregnancy for 357 (73%) women, during labor for 22 (5%) women, and shortly after delivery for 48 (10%) women. Antenatal zidovudine (ZDV) was used by 347 (71%) women, and intrapartum ZDV was used by 372 (76%) women. Twelve (55%) of the 22 women who first learned of their HIV infection during labor took intrapartum ZDV. All 495 newborn infants started prophylactic ZDV; the first dose was given within 12 hours for 491 (99%) children. Ten (2%) children were breast-fed at least once by their mother, and 10 (2%) were breast-fed at least once by someone else. Although uptake of services was high, inconsistent antenatal care, fear of stigmatization, and difficulty in disclosing HIV status prevented some women from using services.

Voluntary HIV counseling and testing of pregnant women--an assessment of compliance with Michigan public health statutes

OBJECTIVES

First, to evaluate compliance with Michigan's laws mandating universal, voluntary HIV counseling and testing (VCT) of all pregnant women who provide informed consent (ie, the "opt-out strategy"). Second, to assess the acceptability of and agreement to VCT.

METHODS

Women who delivered a live infant at a large, urban academic medical center were interviewed before hospital discharge. Obstetric and prenatal medical records were abstracted to document that VCT was offered, accepted, or declined and that pre- and posttest counseling were provided and test results noted.

RESULTS

Our survey of 491 postpartum women interviewed from February 1998 through January 1999 revealed that 83% reported that they were offered VCT; of those, 95% reported that they had agreed to testing. Uninsured women were least likely to undergo VCT; no other demographic, social, or behavioral characteristics were associated with VCT. Nor was VCT more likely to occur according to providers' different practice settings (ie, "private" vs publicly funded). Most women reported that they did not find VCT offensive or threatening, although only 49% reported that they felt "very comfortable," refusing testing.

CONCLUSION

These results suggest the opt-out strategy for VCT, as currently practiced in Michigan, can effectively promote the US Public Health Service testing goals. Offering VCT with the understanding that it may be refused without risk is essential. Additional educational interventions about HIV infection during pregnancy and perinatal HIV-transmission interruption were requested by women in our study and should be widely promoted. Given that 95% of women agreed to VCT, mandatory testing without consent is not needed to achieve federal testing benchmarks and seems ethically problematic.

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 HIV counseling, testing, and antiretroviral prophylaxis by obstetric and family medicine providers in Alabama

BACKGROUND

The study reported here assessed the implementation of recommendations for routine universal prenatal counseling and voluntary HIV testing among Alabama physicians who provide prenatal care and determined factors associated with noncompliance.

METHODS

Voluntary, confidential mailed survey of obstetrics and family medicine practitioners.

RESULTS

Of the 138 physicians who responded to a mailed survey in Alabama, 17 (12.3%) indicated that they did not offer universal HIV counseling and testing to pregnant women. Factors associated with failure to offer universal HIV counseling and testing included having more than 50% of patients refuse HIV counseling and testing when offered and never knowingly having given prenatal/perinatal care to women with HIV. Low/medium familiarity with the US Public Health Service recommendations for perinatal zidovudine use to reduce HIV transmission and physician specialty are also suggested as predictors of not offering universal testing.

CONCLUSIONS

Despite the well-established benefits of antiretroviral prophylaxis to prevent vertical transmission of HIV, some physicians in Alabama have been slow to adopt universal testing of their pregnant patients for HIV in the prenatal period. Practitioner education is as important as patient education in eliminating pediatric HIV in the Deep South.

Understanding correlates of hepatitis B virus vaccination in men who have sex with men: what have we learned?

OBJECTIVES

Hepatitis B infection (HBV) is prevalent among men who have sex with men (MSM) and may lead to significant morbidity and death. Although an effective vaccine exists vaccination rates among MSM are low. We conducted a systematic review to synthesise the various findings from empirical correlational studies to understand HBV vaccination and series completion among MSM.

METHODS

We systematically searched the Medline, PubMed, EMBASE, CINAHL, ERIC, and Web of Science databases to identify the breadth of published studies pertaining to HBV vaccination among MSM and to synthesise findings from these studies to better identify common themes that may direct future research and intervention approaches.

RESULTS

Eight papers specifically addressed correlates of HBV vaccination among MSM. Six domains were identified as predictors of vaccination: (1) demographic variables such as younger age and higher education level; (2) knowledge of the vaccine; (3) access to health care; (4) level of "outness" regarding one's same sex sexual orientation; (5) behavioural factors including sexual and drug use behaviour; and (6) psychosocial variables. Three papers addressed predictors of vaccine series completion among MSM, observing two main domains: (1) demographic variables such as younger age and higher income level; and, (2) behavioural factors including sexual and health promotion behaviours.

CONCLUSIONS

Continued educational efforts, creation of environments that facilitate proper risk factor evaluation, and access to low cost vaccine may facilitate vaccine uptake. Although we observed important trends in the studies we reviewed, there is a lack of empirical research regarding this important public health issue.

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.

Potential barriers to seeking human immunodeficiency virus testing among adults in the United States: data from the 1998 National Health Interview Survey

To assess potential barriers to seeking human immunodeficiency virus (HIV) testing among adults in the United States, data from the 1998 National Health Interview Survey (NHIS) were analyzed. The NHIS is a multistage cluster survey of the United States noninstitutionalized civilian population ages 18 years or older. The 1998 NHIS survey was conducted using the computer-assisted personal interview. Of a nationally representative sample (n = 32,440) of the U.S. noninstitutionalized civilian population, 21,410 (66%) have never been tested for HIV, 9,728 (30%) have been tested, and 1302 (4%) did not complete the survey or refused to answer the question. Among individuals who completed the survey, men (odds ratio [OR]: 1.08, 95% confidence interval [CI] = 1.04, 1,22), individuals ages 50 years or older (OR: 4.01, 95% CI = 3.16, 5.08), or 18-19 years (OR: 2.12, 95% CI = 1.71, 2.63), those who had "up to 11 grade" level of education (OR: 2.16, 95% CI = 1.74, 2.63), those who lived in nonmetropolitan areas (OR: 1.21, 95% CI = 1.14, 1.28), or lived in the Midwest (1.34, 95% CI = 1.24, 1.43) were significantly more likely than their counterparts to have not sought HIV testing. Among individuals who have never been tested for HIV, 58% had no particular reason, 38% felt they were not at risk of contracting HIV, whereas less than 1% feared adverse consequences. The high proportion of adults who never tested for HIV after two decades of HIV epidemic underscores the need for new approaches to fight the spread of HIV infection in the United States.

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.

Maternal characteristics associated with antenatal, intrapartum, and neonatal zidovudine use in four US cities, 1994-1998

OBJECTIVES

To evaluate implementation of 1994 United States Public Health Service guidelines for zidovudine (ZDV) use in HIV-infected women and their newborns by describing the prevalence of use of perinatal ZDV and other antiretrovirals and by investigating determinants of not receiving perinatal ZDV.

DESIGN/METHODS

The Perinatal AIDS Collaborative Transmission Study is a prospective cohort study designed to collect information related to mother-to-child HIV transmission that was conducted in New York City (NY), Newark (NJ), Baltimore (MD), and Atlanta (GA), U.S.A. The current analysis was restricted to infants born between July 1994 and June 1998.

RESULTS

Utilization rates for antenatal, intrapartum, and neonatal ZDV increased from 41% to 70% during the 4-year period. Use of combination antiretrovirals increased from fewer than 2% of women in 1994 to 1995 to 35% in 1997 to 1998. Antenatal and neonatal ZDV use increased each year, but intrapartum ZDV use reached a plateau after 1996. Mother-infant pairs with the following characteristics were less likely to have received a complete 3-part ZDV regimen: older maternal age, CD4 count >500 cells/microl, preterm birth, cocaine or heroin use during pregnancy, positive newborn drug screen test result, and smoking or alcohol use during pregnancy. By multivariate logistic regression adjusted for hospital and year of birth, cocaine or heroin use during pregnancy (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.6-3.3), maternal CD4 count (OR, 0.4; 95% CI, 0.2-0.8; comparing <200 with >500 cells/microl), and preterm birth (OR, 1.6; 95% CI, 1.1-2.5) remained independently associated with not receiving the complete ZDV regimen.

CONCLUSIONS

ZDV use by pregnant HIV-infected women and their infants has increased dramatically since publication of the 1994 guidelines. Nevertheless, women who abuse substances, give birth preterm, or have less advanced immunosuppression, were at substantial risk of not receiving the complete ZDV regimen.
