Awareness on Integrated Counseling and Testing Centre (ICTC) among Interns and postgraduates of a Medical College in Bengaluru City

Introduction Studies describing the awareness on Integrated Counseling and Testing Centre ICTC among medical graduates or doctors are not available India and hence the study was taken up with the followingObjectives To assess the awareness about ICTC its functions and services among medical graduates and importance of counseling before and after HIV testing among medical graduates.Materials and Methods A descriptive study among 101 interns and post graduates from various disciplines including pre-clinical paraclinical and clinical specialties of a medical college having a stand-alone ICTC and situated in Bengaluru city was conducted using a pre tested semi-structured questionnaire. Study subjects were asked about awareness about ICTC its functions services and importance of pre-test and post-test counseling. Medical graduates who have completed final year of MBBS were included as study subjects and those not willing to consent for the study were excluded from the study.Results All the study subjects had heard of ICTC but only 37.62 were aware of where the nearest ICTC was located.69.30 were aware of the services provided at an ICTC and only 63.36 knew about the tests conducted at an ICTC. Majority90.09 of the doctors were sure that the confidentiality of the test results will be maintained but only 37.62 knew what aspects should be covered in Pre and Post-test counseling.Conclusion Awareness on the key components of ICTC was not satisfactory among the subjects.

Prenatal screening for genetic disorders: Suggested guidelines for the Indian Scenario.

Prenatal testing is the best strategy for reducing the burden of genetic disorders and congenital disabilities that cause significant postnatal functional impairment. Universal prenatal screening is advisable for common genetic disorders and congenital anomalies such as Down syndrome, beta-thalassaemia and neural tube defects. Several prenatal-screening tests are now available for Down syndrome, but knowledge about the appropriate timing of the test and the need for pre- and post-test counselling may not be updated among the primary care physicians. There is also a considerable degree of confusion regarding the prenatal screening test to be chosen in each case, due to the availability of a number of new and advanced screening techniques. At present, there is no nation-wide consensus regarding the nature and timing of these prenatal-screening protocols. Due to the absence of any definite guidelines and the additional lacunae in the awareness regarding the appropriate prenatal screening in the country, the optimum benefits of these screening protocols are not reaching the population. This review focuses on the various prenatal screening and diagnostic tests that are available for common genetic conditions and congenital disabilities and attempts to outline the most cost-effective and gestational age-appropriate strategies for prenatal screening for the Indian healthcare set-up. The recommendations suggested would serve as a source guide for formulating prenatal-screening guidelines for reducing the incidence of common genetic disorders and congenital disabilities in India.

Prenatal diagnosis of susceptibility loci for neurodevelopmental disorders - genetic counseling and pregnancy outcome in 57 cases.

Whole genome array testing not only provides an increased diagnostic yield of pathogenic causative findings, but it may also reveal so called susceptibility loci (SL) for neurodevelopmental disorders. The goal of this study was to evaluate the pregnancy outcomes in SL cases and to establish a protocol for pregnancy management, follow-up and additional investigations. Fifty seven cases were evaluated: 34 with and 23 without ultrasound anomalies at referral. Each pregnant couple received pretest counseling and extensive posttest genetic counseling. After diagnosis of SL, parental testing and an additional ultrasound examination were offered. The severity of the ultrasound anomalies and not the diagnosis of SL was the most important factor contributing to the decision on pregnancy continuation. In the majority of cases with milder or no ultrasound anomalies, the pregnancy was continued and a normal outcome after birth was observed. The diagnosis of a SL did not seem to be a reason for termination of pregnancy. Most patients were able to cope with the uncertainty and were interested in both prenatal and postnatal actionability of SL. Long-term follow-up is crucial to assess the actual risks for neurodevelopmental disorders, especially in families with unremarkable history. © 2016 John Wiley & Sons, Ltd.

Population screening for BRCA1/BRCA2 founder mutations in Ashkenazi Jews: proactive recruitment compared with self-referral.

Population screening of three common BRCA1/BRCA2 mutations in Ashkenazi Jews (AJ) apparently fulfills screening criteria. We compared streamlined BRCA screening via self-referral with proactive recruitment in medical settings. Unaffected AJ, age ≥25 years without known familial mutations, were either self-referred or recruiter-enrolled. Before testing, participants received written information and self-reported family history (FH). After testing, both non-carriers with significant FH and carriers received in-person genetic counseling. Psychosocial questionnaires were self-administered 1 week and 6 months after enrollment. Of 1,771 participants, 58% were recruiter-enrolled and 42% were self-referred. Screening uptake was 67%. Recruited enrollees were older (mean age 54 vs. 48, P < 0.001) and had less suggestive FH (23 vs. 33%, P < 0.001). Of 32 (1.8%) carriers identified, 40% had no significant FH. Post-test counseling compliance was 100% for carriers and 89% for non-carrier women with FH. All groups expressed high satisfaction (>90%). At 6 months, carriers had significantly increased distress and anxiety, greater knowledge, and similar satisfaction; 90% of participants would recommend general AJ BRCA screening. Streamlined BRCA screening results in high uptake, very high satisfaction, and no excess psychosocial harm. Proactive recruitment captured older women less selected for FH. Further research is necessary to target younger women and assess other populations.Genet Med advance online publication 08 December 2016.

Acceptability Study on HIV Self-Testing among Transgender Women, Men who Have Sex with Men, and Female Entertainment Workers in Cambodia: A Qualitative Analysis.

BackgroundIn Cambodia, HIV prevalence is high while HIV testing rates remain low among transgender women (TG women), men who have sex with men (MSM), and female entertainment workers (FEW). Introducing self-testing for HIV to these key populations (KPs) could potentially overcome the under-diagnosis of HIV and significantly increase testing rates and receipt of the results, and thus could decrease transmission. Therefore, this study aimed to determine the acceptability of HIV self-testing (HIVST) among these three categories of KPs.MethodsThis study was conducted through focus group discussions (FGDs) with TG women, MSM, and FEW in Phnom Penh city, Kampong Cham, Battambang, and Siem Reap provinces of Cambodia. Convenience sampling was used to recruit the participants. Two FGDs (six participants in each FGD) were conducted in each target group in each study site, totaling 24 FGDs (144 participants). Thematic analysis was performed to identify common or divergent patterns across the target groups.ResultsAlmost all participants among the three groups (TG women, MSM, and FEW) had not heard about HIVST, but all of them expressed willingness to try it. They perceived HIVST as confidential, convenient, time-saving, and high-tech. Barriers to obtaining HIVST included cost, access, administration technique, embarrassment, and fear of pain. The majority preferred counseling before and after testing.ConclusionsParticipants showed high willingness to use and acceptability of HIVST due to its confidentiality/privacy and convenience even if it is not linked to a confirmatory test or care and treatment. Notwithstanding, to increase HIVST, the target groups would need affordable self-test kits, education about how to perform HIVST and read results, assurance about accuracy and reliability of HIVST, and provision of post-test counseling and facilitation of linkage to care and treatment.

Acceptability of Rapid HIV Testing Among Latinos in Washington Heights, New York City, New York, USA.

In the United States, human immunodeficiency virus (HIV) has a disproportionately large impact on Latino Americans. This study assessed the acceptability of rapid HIV testing among a sample of Latinos from New York City. A cross-sectional study was conducted with 192 participants from The Washington Heights/Inwood Informatics Infrastructure for Community-Centered Comparative Effectiveness Research (WICER) study. Participants were interviewed and offered rapid HIV testing and post-test counseling. Seventy-five percent (n = 143) accepted rapid HIV testing when offered. More religious participants were less likely than less religious participants to undergo testing (RR = 0.73; 95% CI 0.54-0.99). Participants tested for HIV within the past year were less likely than those who had not been tested within the past year to agree to undergo testing (RR = 0.27; 95% CI 0.11-0.66). Community-based rapid HIV testing is feasible among Latinos in urban environments. Outreach efforts to engage religious individuals and encouraging routine testing should be reinforced.

The effect of a conditional cash transfer on HIV incidence in young women in rural South Africa (HPTN 068): a phase 3, randomised controlled trial

Cash transfers have been proposed as an intervention to reduce HIV-infection risk for young women in sub-Saharan Africa. However, scarce evidence is available about their effect on reducing HIV acquisition. We aimed to assess the effect of a conditional cash transfer on HIV incidence among young women in rural South Africa. We did a phase 3, randomised controlled trial (HPTN 068) in the rural Bushbuckridge subdistrict in Mpumalanga province, South Africa. We included girls aged 13-20 years if they were enrolled in school grades 8-11, not married or pregnant, able to read, they and their parent or guardian both had the necessary documentation necessary to open a bank account, and were residing in the study area and intending to remain until trial completion. Young women (and their parents or guardians) were randomly assigned (1:1), by use of numbered sealed envelopes containing a randomisation assignment card which were numerically ordered with block randomisation, to receive a monthly cash transfer conditional on school attendance (≥80% of school days per month) versus no cash transfer. Participants completed an Audio Computer-Assisted Self-Interview (ACASI), before test HIV counselling, HIV and herpes simplex virus (HSV)-2 testing, and post-test counselling at baseline, then at annual follow-up visits at 12, 24, and 36 months. Parents or guardians completed a Computer-Assisted Personal Interview at baseline and each follow-up visit. A stratified proportional hazards model was used in an intention-to-treat analysis of the primary outcome, HIV incidence, to compare the intervention and control groups. This study is registered at ClinicalTrials.gov (NCT01233531). Between March 5, 2011, and Dec 17, 2012, we recruited 10 134 young women and enrolled 2537 and their parents or guardians to receive a cash transfer programme (n=1225) or not (control group; n=1223). At baseline, the median age of girls was 15 years (IQR 14-17) and 672 (27%) had reported to have ever had sex. 107 incident HIV infections were recorded during the study: 59 cases in 3048 person-years in the intervention group and 48 cases in 2830 person-years in the control group. HIV incidence was not significantly different between those who received a cash transfer (1·94% per person-years) and those who did not (1·70% per person-years; hazard ratio 1·17, 95% CI 0·80-1·72, p=0·42). Cash transfers conditional on school attendance did not reduce HIV incidence in young women. School attendance significantly reduced risk of HIV acquisition, irrespective of study group. Keeping girls in school is important to reduce their HIV-infection risk.

The frequency of incidental findings in expanded carrier screening

To examine the frequency of incidental findings in expanded carrier screening - diseases where carriers may also have clinical health implications (CHI). Expanded carrier screening (ECS) identifies couples at risk for transmitting a genetic condition to their offspring. Patients may be counseled during the informed consent process that carriers of recessive conditions usually do not experience symptoms. Yet, there are several conditions on ECS panels where carriers may have CHI. We analyzed Counsyl laboratory’s experience of over 346,790 expanded carrier screens to calculate this frequency. Individuals were tested for carrier status in up to 108 genes by either targeted genotyping (TG) of up to 417 sites or next-generation sequencing (NGS) of the exons and selected introns of the chosen genes. Carrier frequencies for each condition were calculated as the higher of TG or NGS frequencies. Five autosomal recessive diseases were identified for their association with CHI: Nijmegen breakage syndrome (NBN) for cancer risk; ataxia-telangiectasia (ATM) for breast cancer risk; pseudocholinesterase deficiency (BCHE) for increased risk for prolonged period of breathing paralysis after receiving choline ester drugs; hereditary thymine-uraciluria (DPYD) for risk for toxicity following 5-fluorouracil chemotherapy treatment; and factor XI deficiency (F11) for risk for bleeding problems. Carrier frequencies for each condition were tabulated per ethnic group, weighted by US Census Data 2010, and summated to represent the ethnic distribution in USA. 346,790 patients indicating “routine carrier testing” as the reason for testing were selected from a total population of 430,584 (all indications). From this subset, 308,668 (89%) received TG and 38,122 (11%) received NGS test. The carrier frequencies for each condition were 1/280 (ATM), 1/24 (BCHE), 1/109 (DPYD), 1/150 (F11), and 1/560 (NBN). This summates to an overall frequency of 6.2% for CHI on ECS. BCHE accounted for 67% of the frequency of CHI and is more common in individuals of Ashkenazi Jewish (4.5%) and European descent (4.9%) than those of African (1.0%) or Asian descent (1.2%). 6.2% of individuals (1 in 16) screened for these diseases will have an incidental finding - where carriers identified may experience CHI. Pre-test counseling, informed consent, reporting, and post-test counseling should educate patients and providers regarding this possibility.

The role of people living with HIV as patient instructors – reducing stigma and improving interest around HIV care among medical students

ABSTRACTPeople living with HIV/AIDS (PHAs) are increasingly recognized as experts in HIV and their own health. We developed a simulated clinical encounter (SCE) in which medical students provided HIV pre- and post-test counselling and point-of-care HIV testing for PHAs as patient instructors (PHA-PIs) under clinical preceptor supervision. The study assessed the acceptability of this teaching tool with a focus on assessing impact on HIV-related stigma among medical students. University of Toronto pre-clerkship medical students participated in a series of SCEs facilitated by 16 PHA-PIs and 22 clinical preceptors. Pre- and post-SCE students completed the validated Health Care Provider HIV/AIDS Stigma Scale (HPASS). HPASS measures overall stigma, as well as three domains within HIV stigma: stereotyping, discrimination, and prejudice. Higher scores represented higher levels of stigma. An additional questionnaire measured comfort in providing HIV-related care. Mean scores and results of paired t-tests are presented. Post-SCE, students (n = 62) demonstrated decreased overall stigma (68.74 vs. 61.81, p < .001) as well as decreased stigma within each domain. Post-SCE, students (n = 67) reported increased comfort in providing HIV-related care (10.24 vs. 18.06, p < .001). Involving PHA-PIs reduced HIV-related stigma among medical students and increased comfort in providing HIV-related care.

Acceptability of a Community-Based Outreach HIV-Testing Intervention Using Oral Fluid Collection Devices and Web-Based HIV Test Result Collection Among Sub-Saharan African Migrants: A Mixed-Method Study.

BackgroundLate human immunodeficiency virus (HIV) diagnosis is common among sub-Saharan African migrants. To address their barriers to HIV testing uptake and improve timely HIV diagnoses and linkage to care, the outreach HIV testing intervention, “swab2know,” was developed. It combined a community-based approach with innovative testing methods: oral fluid self-sampling and the choice between Web-based HIV test result collections using a secured website or post-test counseling at a sexual health clinic. The sessions included an informational speech delivered by a physician of sub-Saharan African origin and testimonies by community members living with HIV.ObjectivesThe objectives of this study were to evaluate the intervention’s acceptability among sub-Saharan African migrants and its potential to reach subgroups at higher risk for HIV infection and to identify facilitators and barriers for HIV testing uptake.MethodsThis mixed-method study combined qualitative (participant observations and informal interviews with testers and nontesters) and quantitative data (paper–pencil survey, laboratory data, and result collection files). Data were analyzed using a content analytical approach for qualitative and univariate analysis for quantitative data.ResultsA total of 10 testing sessions were organized in sub-Saharan African migrant community venues in the city of Antwerp, Belgium, between December 2012 and June 2013. Overall, 18.2% of all people present (N=780) underwent HIV testing; 29.8% of them tested for HIV for the first time, 22.3% did not have a general practitioner, and 21.5% reported 2 or more sexual partners (last 3 months). Overall, 56.3% of participants chose to collect their HIV test results via the protected website. In total, 78.9% collected their results. The qualitative analysis of 137 participant observation field notes showed that personal needs and Internet literacy determined the choice of result collection method. Generally, the oral fluid collection devices were well accepted mainly because sub-Saharan African migrants dislike blood taking. For some participants, the method raised concerns about HIV transmission via saliva. The combination of information sessions, testimonies, and oral fluid collection devices was perceived as effectively reducing thresholds to participation. Acceptability of the intervention differed between individual participants and settings. Acceptance was higher among women, in churches and settings where community leaders were engaged in HIV awareness raising. Higher preventive outcomes were observed in settings with lower acceptance. The presence of the intervention team visualized the magnitude of the HIV epidemic to the public and promoted HIV testing uptake at large, for example, those who declined indicated they would take up testing later.ConclusionsWhen accompanied by tailored provision of information, outreach HIV testing interventions adopting a community-based approach and innovative methods such as Web-based result collection and oral fluid collection devices are acceptable and reduce thresholds for HIV testing uptake. The swab2know intervention was able to reach sub-Saharan African migrants at risk of HIV infection, and with limited access to regular HIV testing. Among nontesters, the intervention contributed to awareness raising and therefore has a place in a multipronged HIV test promotion strategy.

Clinical experience of unexpected findings in prenatal array testing.

The aim of this study was to evaluate whether unexpected diagnoses (UD) made by prenatal array testing contribute to pregnancy management. In 2010-2015 in 19/4043 (0.5%) pregnancies an UD was made. The clinical usefulness of UDs was assessed based on the couple's responses during post-test counseling and their decisions. In 16/19 cases, the UD was helpful either for the couples in making a decision about the course of their pregnancy, for perinatal management or family genetic counseling. The majority of the pregnant couples found the UDs relevant for pregnancy management and genetic counseling. This adds another motive for offering whole genome array during pregnancy in patients who wish broad testing of their fetus.

Noninvasive prenatal testing (NIPT) in twin pregnancies with treatment of assisted reproductive techniques (ART) in a single center.

The objective of the study is to report the performance of noninvasive prenatal testing (NIPT) in twin pregnancies after the treatment of assisted reproductive technology (ART). In two years period, 565 pregnant women with ART twin pregnancies were prospectively tested by NIPT for screening for trisomy 21 (T21), 18 (T18), and 13 (T13) by sequencing cell-free DNA in maternal plasma. Positive NIPT results were confirmed by karyotyping, while negative results were interviewed after delivery. Pregnant decision based on NIPT and confirmation results was discussed during post-test counseling. In total of 565 cases, NIPT had a failure rate of 0.9% (5/565). Four cases of T21 were identified by NIPT and confirmed by karyotyping, resulting in 100% (95%CI 39.8%-100%) positive predictive value. Among 556 cases with NIPT negative results, 506 cases (91.0%) were confirmed by follow-up of postnatal phenotypes, while 33 cases (5.9%) had adverse pregnant outcomes with unconfirmed reasons because of the lack of cytogenetic samples. The remaining 17 cases (3.1%) refused follow-up. No false negative result was reported. With apparently high positive predictive value and low false positive rate, NIPT has the potential to be used as a good alternative approach of conventional prenatal screening at the first trimester in ART twin pregnancy. © 2016 John Wiley & Sons, Ltd.

Presymptomatic ALS genetic counseling and testing: Experience and recommendations.

Remarkable advances in our understanding of the genetic contributions to amyotrophic lateral sclerosis (ALS) have sparked discussion and debate about whether clinical genetic testing should routinely be offered to patients with ALS. A related, but distinct, question is whether presymptomatic genetic testing should be offered to family members who may be at risk for developing ALS. Existing guidelines for presymptomatic counseling and testing are mostly based on small number of individuals, clinical judgment, and experience from other neurodegenerative disorders. Over the course of the last 8 years, we have provided testing and 317 genetic counseling sessions (including predecision, pretest, posttest, and ad hoc counseling) to 161 first-degree family members participating in the Pre-Symptomatic Familial ALS Study (Pre-fALS), as well as testing and 75 posttest counseling sessions to 63 individuals with familial ALS. Based on this experience, and the real-world challenges we have had to overcome in the process, we recommend an updated set of guidelines for providing presymptomatic genetic counseling and testing to people at high genetic risk for developing ALS. These recommendations are especially timely and relevant given the growing interest in studying presymptomatic ALS.

Testing in the HIV Counselling and Testing (HCT) campaign, HIV risk behaviours and ART enrolment in South Africa

ObjectivesTo examine the association between testing in the 2010 HIV Testing and Counselling (HCT) campaign with HIV risk behaviours and enrolment on ART. Study designData for this study were collected as part of a nationally representative cross-sectional household survey conducted in 2012 in South Africa. MethodsConsenting participants completed a structured questionnaire and provided a dry blood spot specimen which was tested for HIV antibodies and antiretroviral drugs. Multinomial logistic regression was used to examine the association between HIV testing history and explanatory variables of interest. ResultsThere was no association between testing in the 2010 HCT campaign and condom use at last sex, number of sexual partnerships or HIV knowledge. Individuals who tested in the HCT campaign were more likely to disclose their status (COR 2.6, 95% CI: 1.71–3.8) and those who tested HIV positive in the campaign were more likely to be receiving ART (COR 1.8, 95% CI: 1.1–2.9). Testing in the HCT campaign was associated with having received both pretest and post-test counselling while testing before the campaign was associated with having received HIV results with no counselling (COR 2.1, 95% CI: 1.2–3.8). ConclusionWe highlight the success of the 2010 HCT campaign in improving HIV status disclosure and enrolment on ART as well as shortcomings on HIV risk behaviours and HIV knowledge. These may be related to issues of quality assurance in the counselling process. Our results further highlight possible HCT counselling inconsistencies across sectors requiring stronger public-private partnership in the delivery of HCT in South Africa.

Testing and Linking Foreign-Born People with Chronic Hepatitis B Virus Infection to Care at Nine U.S. Programs, 2012-2014.

Hepatitis B virus (HBV) infection continues to be a public health threat in the United States. As many as 2.2 million people are infected, approximately 70% of whom are foreign-born, and fewer than one-third are aware of their infection. We launched an HBV testing and linkage-to-care initiative among foreign-born people. As part of the Hepatitis Testing and Linkage to Care (HepTLC) initiative, which promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites, nine U.S. programs in seven states conducted HBV screening from October 2012 to September 2014. The nine programs partnered with health-care centers and community-based organizations to recruit foreign-born people recommended for HBV testing. We assessed patient characteristics, region of origin, risk factors, hepatitis B surface antigen (HBsAg) status, and referral to medical care. Of 23,144 participants tested for HBV, 1,317 (5.7%) were HBsAg positive. Of these, the median age was 47 years, 1,205 (91%) had at least one risk factor for HBV infection, 1,117 (85%) received posttest counseling, 1,098 (83%) were referred to care, and 606 (46%) attended a first medical appointment. The proportion of HBsAg-positive participants by region of origin included Africa (10%, 206/2,129), Western Pacific (6%, 616/9,673), Eastern Mediterranean (5%, 174/3,337), Southeast Asia (5%, 191/3,891), South America (2%, 6/252), Eastern Europe (2%, 6/262), and North America (1%, 17/1,936). Community-based HBV testing initiatives can identify substantial numbers of people with chronic HBV infection, inform them of their infection status, and provide posttest counseling and linkage to care. However, strategies are needed to improve linkage to HBV-directed medical care for foreign-born individuals living with chronic HBV infection.

High-Yield Birth-Cohort Hepatitis C Virus Screening and Linkage to Care Among Underserved African Americans, Atlanta, Georgia, 2012-2013.

Hepatitis C virus (HCV) infection disproportionately affects certain populations, including those born between 1945 and 1965 (i.e., baby boomers) and African Americans. As part of the Hepatitis Testing and Linkage to Care initiative, which promoted hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites, we conducted routine HCV screening to identify previously undiagnosed, primarily African American baby boomers with chronic hepatitis C infection and link them to care. We launched the Internal Medicine Trainees Identifying and Linking to Treatment for Hepatitis C (TILT-C) initiative at the Grady Memorial Hospital Primary Care Center and Grady Liver Clinic in Atlanta, Georgia, in October 2012, and present results from the first year. TILT-C faculty implemented an electronic medical record prompt and conducted educational sessions to boost HCV screening. A project coordinator tracked testing outcomes and linked HCV-positive patients to care. Of 2,894 patients tested for anti-HCV, 201 (6.9%) tested positive. Men had a significantly higher (p<0.001) prevalence of HCV infection than women, with 106 of 1,091 (9.7%) men compared with 95 of 1,803 (5.3%) women testing anti-HCV positive. A total of 174 of 201 (86.6%) anti-HCV-positive patients received HCV ribonucleic acid (RNA) testing. Of 124 patients with a positive HCV RNA test, 122 were referred to care and 120 attended the first appointment. The TILT-C screening program was feasible and effective in detecting previously undiagnosed HCV infection and linking patients to care. The unexpectedly high prevalence of HCV infection in this primarily African American, baby boomer population underscores the need for aggressive HCV screening efforts in similar populations.

Improving Screening Methods for Hepatitis C Among People Who Inject Drugs: Findings from the HepTLC Initiative, 2012-2014.

People who inject drugs (PWID) are at increased risk for hepatitis C virus (HCV) infection. We examined HCV testing outcomes among PWID through CDC's Hepatitis Testing and Linkage to Care initiative, which promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites during 2012-2014. Ten grantees in nine geographically diverse cities conducted HCV testing among PWID. Among those testing positive for HCV antibody (anti-HCV), we calculated the proportion who were offered a confirmatory HCV ribonucleic acid (RNA) test, positively diagnosed, and referred to a specialist for care. We stratified anti-HCV-positive people who completed each step by same-day testing (i.e., an HCV RNA test administered on the same date as an anti-HCV test) vs. person not receiving same-day testing to evaluate whether the need for follow-up testing affected diagnosis of chronic infection and linkage to care. A total of 15,274 people received an anti-HCV test at 84 testing sites targeting PWID. Of those, 11,159 (73%) reported having injected drugs in their lifetime, 7,789 (51%) reported injecting drugs in the past 12 months, and 3,495 (23%) tested anti-HCV positive. A total of 1,630 people received testing for HCV RNA, of whom 1,244 (76%) were HCV RNA positive. When not receiving both tests on the same day, 601 of 2,465 (24%) anti-HCV-positive people received an HCV RNA test. Strategies to diagnose PWID for HCV infection are needed to reduce associated morbidity and mortality. Agencies can substantially increase the number of PWID who are diagnosed and informed of their HCV infection by administering both anti-HCV and HCV RNA tests during a single testing event.

Increasing Hepatitis B Testing and Linkage to Care of Foreign-Born Asians, Sacramento, California, 2012–2013

Without medical intervention, about one-quarter of the 1.4-2.2 million Americans chronically infected with the hepatitis B virus (HBV) will die of HBV-associated conditions, including liver failure and hepatocellular carcinoma. We report on a program in Sacramento County, California, that offered HBV screening to at-risk adults, referred infected individuals to care, and vaccinated uninfected adults who were susceptible to HBV infection (i.e., individuals who tested negative for hepatitis B surface antigen and who were never vaccinated against HBV). We engaged organizations linked to Chinese, Hmong, Korean, and Vietnamese communities to cosponsor HBV screenings of Asian Americans as part of the Hepatitis Testing and Linkage to Care initiative, which promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites. We held 28 hepatitis B community screening events throughout Sacramento County, California, in collaboration with these groups from September 2012 to September 2013. We screened 1,004 Asian American adults (i.e., 283 Koreans, 242 Chinese, 233 Vietnamese, 223 Hmong, and 23 people from other Asian communities) for HBV, of whom 98% were foreign born and 87% had a language preference other than English. Of the 76 participants who tested positive for HBV (31 Hmong, 23 Vietnamese, 17 Chinese, two Koreans, and three from other Asian communities), we provided posttest counseling to 51 participants. By collaborating with community groups and addressing barriers to screening, we highlighted the importance of disaggregating chronic HBV infection rates by Asian ethnicity and sex vs. aggregated Asian American rates. Future HBV screening initiatives should target Hmong and Vietnamese men.

Impact of the Hepatitis Testing and Linkage to Care (HepTLC) Initiative on Linkage to Care for Minnesota Refugees with Hepatitis B, 2012-2014.

The Hepatitis Testing and Linkage to Care (HepTLC) initiative promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites from 2012 to 2014. Through the HepTLC initiative, the Minnesota Department of Health (MDH) and clinic partners began conducting linkage-to-care activities with hepatitis B-positive refugees in October 2012. This intervention provided culturally appropriate support to link refugees to follow-up care for hepatitis B. MDH refugee health and viral hepatitis surveillance programs, along with clinics that screened newly arrived refugees in Hennepin and Ramsey counties in Minnesota, collaborated on the project, which took place from October 1, 2012, through September 30, 2014. Bilingual care navigators contacted refugees to provide education, make appointments, and arrange transportation. We compared the linkage-to-care rate for participants with the rates for refugees screened the year before project launch using a two-sample test of proportions. In the year preceding the project (October 2011 through September 2012), 87 newly arrived refugees had a positive hepatitis B surface antigen (HBsAg) test. Fifty-six (64%) refugees received follow-up care, 12 (14%) refugees did not receive follow-up care, and 19 (22%) refugees could not be located and had no record of follow-up care. During the project, 174 HBsAg-positive, newly arrived refugees were screened. Of those 174 refugees, 162 (93%) received follow-up care, seven (4%) did not receive follow-up care, and five (3%) could not be located and had no record of follow-up care. The one-year linkage-to-care rate for project participants (93%) was significantly higher than the rate for refugees screened the previous year (64%) (p<0.001). In the context of a strong screening and surveillance infrastructure, a simple intervention improved the linkage-to-care rate for HBsAg-positive refugees.
