In April 2015, the Georgian government, in collaboration with CDC and other partners, launched a national program to eliminate HCV through scaling up HCV treatment and prevention interventions, with the aim of achieving a 90% reduction in prevalence by 2020. We evaluate the interim impact of the HCV treatment program as of 31 October 2017, and assess the feasibility of achieving the elimination goal by 2020.Method We developed a dynamic HCV transmission model to capture the current and historical epidemic dynamics of HCV in Georgia, including the main drivers of transmission. Using the 2015 national sero-survey and prior surveys conducted among people who inject drugs (PWID) from 1997-2015, the model was calibrated to data on HCV prevalence by age, gender and PWID status, and the age distribution of PWID. We use the model to project the interim impact of treatment strategies currently being undertaken as part of the ongoing Georgia HCV elimination program, while accounting for treatment failure/loss to follow up, in order to determine whether they are on track to achieving their HCV elimination target by 2020, or whether strategies need to be modified to ensure success.Results A treatment rate of 2,050 patients/month was required from the beginning of the national program to achieve a 90% reduction in prevalence by the end of 2020, with equal treatment rates of PWID and the general population. From May 2015 to October 2017, 40,420 patients were treated, an average of ~1,350 per month; although the treatment rate has recently declined from a peak of 4,500/month in September 2016 to 2100/month in November-December 2016, and 1000/month in August-October 2017, with a sustained virological response rate (SVR) of 98% per-protocol or 78% intent to treat. The model projects that the treatments undertaken up to October 2017 have reduced adult chronic prevalence by 26% (18-35%) to 3.7% (2.9-5.1%), reduced total incidence by 25% (15-35%), and prevented 1845 (751-3969) new infections and 93 (31-177) HCV-related deaths. If the treatment rate of 1000 patients initiated per month continues, prevalence will have halved by 2020, and reduce by 90% by 2026. In order to reach a 90% reduction by 2020, the treatment rate must increase 3.5-fold to 4000/month.Conclusion The Georgia HCV elimination program has accomplished an impressive scale up of treatment, which has already impacted on prevalence and incidence, and averted deaths due to HCV. However, extensive scale up is needed to achieve a 90% reduction in prevalence by 2020. |

J Clin Exp Hepatol 2022 12 (5) 1310-1319 BACKGROUND: The prevalence of hepatitis B virus (HBV) infection in Punjab, India, is unknown. Understanding the statewide prevalence and epidemiology can help guide public health campaigns to reduce the burden of disease and promote elimination efforts. METHODS: A cross-sectional, population-based survey was conducted from October 2013 to April 2014 using a multistage stratified cluster sampling design. All members of selected households aged ≥5 years were eligible. Participants were surveyed for demographics and risk behaviors; serum samples were tested for total antibody to hepatitis B core (total anti-HBc), hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody (anti-HCV), and HCV RNA. HBsAg-positive specimens were tested for HBV genotype. RESULTS: A total of 5543 individuals participated in the survey and provided serum samples. The prevalence of total anti-HBc was 15.2% (95% confidence interval [95% CI]: 14.1-16.5) and HBsAg was 1.4% (95% CI: 1.0-1.9). Total anti-HBc positivity was associated with male sex (adjusted odds ratio [aOR] 1.46; 95% CI: 1.21-1.75), older age (aOR 3.31; 95% CI: 2.28-4.79 for ≥60 vs. 19-29 years), and living in a rural area (aOR 2.02; 95% CI: 1.62-2.51). Receipt of therapeutic injections in the past 6 months also increased risk (4-8 injections vs. none; aOR 1.39; 95% CI: 1.05-1.84). Among those positive for total anti-HBc, 10.4% (95% CI: 8.1-13.2) were also anti-HCV positive. CONCLUSION: Punjab has a substantial burden of HBV infection. Hepatitis B vaccination programs and interventions to minimize the use of therapeutic injections, particularly in rural areas, should be considered. |

Liver Int 2022 43 (3) 558-568 BACKGROUND AND AIMS: In 2015, the country of Georgia launched an elimination program aiming to reduce prevalence of Hepatitis C virus (HCV) infection by 90% from 5.4% prevalence (~150,000 people). During the first 2.5 years of the program, 770,832 people were screened, 48,575 were diagnosed with active HCV infection, and 41,483 patients were treated with direct-acting antiviral (DAA) based regimens, with >95% cure rate. METHODS: We modelled the incremental cost-effectiveness ratio (ICER) of HCV screening, diagnosis, and treatment between April 2015 and November 2017 compared to no treatment, in terms of cost per quality-adjusted life year (QALY) gained in 2017 US dollars, with 3% discount rate over 25 years. We compared the ICER to willingness-to-pay (WTP) thresholds of US$4357 (GDP) and US$871 (opportunity-cost) per QALY gained. RESULTS: The average cost of screening, HCV viremia testing, and treatment per patient treated was $386 to the provider, $225 to the patient, and $1042 for generic DAAs. At 3% discounting, 0.57 QALYs were gained per patient treated. The ICER from the perspective of the provider including generic DAAs was $2,285 per QALY gained, which is cost-effective at the $4357 WTP threshold, while if patient costs are included it's just above the threshold at $4,398/QALY. All other scenarios examined in sensitivity analyses remain cost-effective except for assuming a shorter time horizon to end of 2025, or including list price DAA cost. Reducing or excluding DAA costs reduced the ICER below the opportunity-cost WTP threshold. CONCLUSIONS: The Georgian HCV elimination program provides valuable evidence that national programs for scaling up HCV screening and treatment for achieving HCV elimination can be cost-effective. |

Subst Abuse Treat Prev Policy 2022 17 (1) 23 BACKGROUND: People who inject drugs (PWID) in Georgia have a high prevalence of hepatitis C virus antibody (anti-HCV). Access to care among PWID could be prioritized to meet the country's hepatitis C elimination goals. This study assesses barriers of linkage to HCV viremia testing among PWID in Georgia. METHODS: Study participants were enrolled from 13 harm reduction (HR) centers throughout Georgia. Anti-HCV positive PWID who were tested for viremia (complete diagnosis [CD]), were compared to those not tested for viremia within 90days of screening anti-HCV positive (not complete diagnosis [NCD]). Convenience samples of CD and NCD individuals recorded at HR centers using beneficiaries' national ID were drawn from the National HCV Elimination Program database. Participants were interviewed about potential barriers to seeking care. RESULTS: A total of 500 PWID were enrolled, 245 CD and 255 NCD. CD and NCD were similar with respect to gender, age, employment status, education, knowledge of anti-HCV status, and confidence/trust in the elimination program (p>0.05). More NCD (13.0%) than CD (7.4%) stated they were not sufficiently informed what to do after screening anti-HCV positive (p<0.05). In multivariate analysis, HCV viremia testing was associated with perceived affordability of the elimination program (adjusted prevalence ratio=8.53; 95% confidence interval: 4.14-17.62). CONCLUSIONS: Post testing counselling and making hepatitis C services affordable could help increase HCV viremia testing among PWID in Georgia. |

Butsashvili M , Zurashvili T , Kamkamidze G , Kajaia M , Gulbiani L , Gamezardashvili A , Gvinjilia L , Kuchuloria T , Gamkrelidze A , Shadaker S , Nasrullah M , Averhoff F , Armstrong PA . J Med Screen 2022 29 (2) 9691413221086497 OBJECTIVES: Georgia has a high prevalence of hepatitis C virus (HCV) infection. In 2015 a national HCV elimination program was launched providing free access to screening and treatment. To achieve elimination, innovative approaches to increase screening coverage and linkage to care are needed. This study estimates feasibility, acceptability, and outcomes of the door-to-door pilot HCV testing program in three cities. METHODS: Households were approached by system random sampling and all members were invited for study participation. Researchers used a detailed guide for conducting door-to-door testing and served as case navigators to link anti-HCV-positive individuals to care. RESULTS: Testing acceptance rate was high. In total 4804 individuals were tested and 48 (1.0%) were HCV positive. Among the entire sample of newly and previously tested individuals, overall HCV antibody prevalence was 3.6%. Through case navigation, of 48 newly identified and 26 previously identified anti-HCV-positive individuals, 42 (87.5%) and 17 (65.4%), respectively, were successfully linked to care. CONCLUSIONS: Door-to-door HCV testing has potential to increase testing uptake. Such community-based approaches not only improve testing, but can also serve to increase linkage to care, which is important in achieving the goal of HCV elimination. The study provides a model for high prevalence countries aiming to eliminate hepatitis C. |
Progress toward hepatitis B and hepatitis C elimination using a catalytic funding model - Tashkent, Uzbekistan, December 6, 2019-March 15, 2020
Dunn R , Musabaev E , Razavi H , Sadirova S , Bakieva S , Razavi-Shearer K , Brigida K , Kamili S , Averhoff F , Nasrullah M . MMWR Morb Mortal Wkly Rep 2020 69 (34) 1161-1165 In 2016, the World Health Organization (WHO) set hepatitis elimination targets of 90% reduction in incidence and 65% reduction in mortality worldwide by 2030 (1). Hepatitis B virus (HBV) and hepatitis C virus (HCV) infection prevalences are high in Uzbekistan, which lacks funding for meeting WHO's targets. In the absence of large financial donor programs for eliminating HBV and HCV infections, insufficient funding is an important barrier to achieving those targets in Uzbekistan and other low- and middle-income countries. A pilot program using a catalytic funding model, including simplified test-and-treat strategies, was launched in Tashkent, Uzbekistan, in December 2019. Catalytic funding is a mechanism by which the total cost of a program is paid for by multiple funding sources but is begun with upfront capital that is considerably less than the total program cost. Ongoing costs, including those for testing and treatment, are covered by payments from 80% of the enrolled patients, who purchase medications at a small premium that subsidizes the 20% who cannot afford treatment and therefore receive free medication. The 1-year pilot program set a target of testing 250,000 adults for HBV and HCV infection and treating all patients who have active infection, including those who had a positive test result for hepatitis B surface antigen (HBsAg) and those who had a positive test result for HCV core antigen. During the first 3 months of the program, 24,821 persons were tested for HBV and HCV infections. Among those tested, 1,084 (4.4%) had positive test results for HBsAg, and 1,075 (4.3%) had positive test results for HCV antibody (anti-HCV). Among those infected, 275 (25.4%) initiated treatment for HBV, and 163 (15.2%) initiated treatment for HCV, of whom 86.5% paid for medications and 13.5% received medications at no cost. Early results demonstrate willingness of patients to pay for treatment if costs are low, which can offset elimination costs. However, improvements across the continuum of care are needed to recover the upfront investment. Lessons learned from this program, including the effectiveness of using simplified test-and-treat guidelines, general practitioners in lieu of specialist physicians, and innovative financing to reduce costs, can guide similar initiatives in other countries and help curb the global epidemic of viral hepatitis, especially among low- and middle-income countries. |

Public Health 2020 185 341-347 OBJECTIVES: The burden of hepatitis B virus (HBV) and hepatitis D virus (HDV) infections is unknown in Georgia. This analysis describes the prevalence of hepatitis B and coinfection with HDV and the demographic characteristics and risk factors for persons with HBV infection in Georgia. STUDY DESIGN: This is a cross-sectional seroprevalence study. METHODS: A cross-sectional, nationwide survey to assess hepatitis B prevalence among the general adult Georgian population (age ≥18 years) was conducted in 2015. Demographic and risk behavior data were collected. Blood specimens were screened for anti-hepatitis B core total antibody (anti-HBc). Anti-HBc-positive specimens were tested for hepatitis B surface antigen (HBsAg). HBsAg-positive specimens were tested for HBV and HDV nucleic acid. Nationally weighted prevalence estimates and adjusted odds ratios (aORs) for potential risk factors were determined for anti-HBc and HBsAg positivity. RESULTS: The national prevalence of anti-HBc and HBsAg positivity among adults were 25.9% and 2.9%, respectively. Persons aged ≥70 years had the highest anti-HBc positivity (32.7%), but the lowest HBsAg positivity prevalence (1.3%). Anti-HBc positivity was associated with injection drug use (aOR = 2.34; 95% confidence interval [CI] = 1.46-3.74), receipt of a blood transfusion (aOR = 1.68; 95% CI = 1.32-2.15), and sex with a commercial sex worker (aOR = 1.46; 95% CI = 1.06-2.01). HBsAg positivity was associated with receipt of a blood transfusion (aOR = 2.72; 95% CI = 1.54-4.80) and past incarceration (aOR = 2.72; 95% CI = 1.25-5.93). Among HBsAg-positive persons, 0.9% (95% CI = 0.0-2.0) were HDV coinfected. CONCLUSIONS: Georgia has an intermediate to high burden of hepatitis B, and the prevalence of HDV coinfection among HBV-infected persons is low. Existing infrastructure for hepatitis C elimination could be leveraged to promote hepatitis B elimination. |

Int J Drug Policy 2020 84 102893 BACKGROUND: Georgia launched national HCV elimination program in 2015. PWID may experience barriers to accessing HCV care. To improve linkage to care among PWID, pilot program to integrate HCV treatment with HR services at opiate substitution therapy (OST) centers and needle syringe program (NSP) sites was initiated. Our study aimed to assess satisfaction of patients with integrated HCV treatment services at HR centers. METHODS: Survey was conducted among convenience sample of patients receiving HCV treatment at 5 integrated care sites and 4 specialized clinics not providing HR services. Simplified pre-treatment diagnostic algorithm and treatment monitoring procedure was introduced for HCV treatment programs at OST/NSP centers which includes fewer pre-treatment and monitoring tests compared to standard algorithm. RESULTS: In total, 358 patients participated in the survey - 48.6% receiving HCV treatment at the specialized clinics while 51.4% at HR site with integrated treatment. Similar proportions of surveyed patients at HR sites (88.0%) and clinics (84.5%) stated that they did not face any barriers to enrollment in the elimination program. Most patients from HR pilot sites and specialized clinics stated that they received comprehensive information about the treatment (98.4% vs 94.3%; p<0.010). 95% of respondents at both sites were confident that confidentiality was completely protected during treatment. Higher proportion of patients at pilot sites thought that HCV treatment services provided at facility were good compared to those from the specialized clinics (85.3% vs 81.0%). We found significant difference in the time to treatment, measured as average time from viremia testing to administration of first dose of HCV medication: 42.9% of patients at pilot sites vs 4.6% at specialized clinics received the first dose of medication within two weeks. CONCLUSION: Quality of services and perceived satisfaction of patients receiving treatment, suggests that integration of HCV treatment with HR services is feasible. |

Butsashvili M , Gvinjilia L , Kamkamidze G , Metreveli D , Dvali S , Rukhadze T , Gamkrelidze A , Nasrullah M , Shadaker S , Morgan J , Averhoff F . BMC Res Notes 2020 13 (1) 332 OBJECTIVE: In 2015, Georgia launched HCV elimination program. Initially, patients with advanced liver disease were treated with sofosbuvir-based regimen-the only DAA available for all genotypes. Purpose of the study was assessing real-world data of treatment outcome among patients with HCV GEN3 and advanced liver fibrosis with sofosbuvir-based regimens. RESULTS: Totally 1525 genotype 3 patients were eligible for analysis; most (72.6%) were aged > 45 years, majority were males (95.1%), and all (100%) had advanced liver disease (F3 or F4 by METAVIR score based on elastography). Of those who received sofosbuvir/ribavirin (SOF/RBV) for 24 weeks, 79.3% achieved SVR, while 96.5% who received sofosbuvir/pegylated interferon/ribavirin (SOF/PEG/RBV) for 12 weeks achieved SVR (p < 0.01). Among patients with liver cirrhosis (defined as F4) overall cure rate was 85.7% as opposed to 96.4% for those with F3. Females were more likely to be cured (98.7% vs 89.7%; OR = 8.54). Patients aged 31-45 years had higher likelihood of achieving SVR compared to patients aged 46-60 years (95.7% vs 87.4%; OR = 0.32,). Independent predictors of SVR were treatment with SOF/PEG/RBV (aOR = 6.72) and lower fibrosis stage (F3) (aOR = 4.18). Real-world experience among HCV GEN3 patients with advanced liver fibrosis and treated by sofosbuvir regimen w/o PEGIFN, demonstrated overall high SVR rate. |
Gender disparity in academic rank and productivity among public health physician faculty in North America
Lee D , Jalal S , Nasrullah M , Ding J , Sanelli P , Khosa F . Cureus 2020 12 (6) e8553 Background The issue of gender disparity is particularly important in the domain of public health where the tone of its leadership is pivotal in bringing about impactful change to research, policies, and the wellbeing of our various populations. Our aim is to explore the gender disparity of author metrics and academic rankings of public health physician faculty through a cross-sectional study. Methods Data collection for this retrospective cross-sectional study took place during June and July of 2017. Public health and preventive medicine residency training programs in the United States and Canada were to compiled and all faculty members that met the inclusion criteria were recorded (n = 973). Variables of interest include gender, h-index, years of active research, and academic appointments. SCOPUS database (Elsevier, Amsterdam, the Netherlands) was used to generate author metrics, and all statistical tests were performed using Statistical Package for the Social Sciences (SPSS) software version 20 (IBM Corp., Armonk, NY). Results Overall, 31.14% (n = 303) of faculty members we studied were from Canada, and 68.86% (n = 670) were from the United States. In both countries, males made up the majority of all faculty members. Female faculty comprised most of the early career positions, and their proportions tapered off with higher academic rank, whereas male faculty trended in the opposite direction. Males generally were higher in all academic measures across all appointments. Conclusions Gender disparity exists within the North American public health and preventive medicine discipline. There are underlying factors preventing women from moving beyond early career positions or engaging in academic research. |
Screening and linkage to care for hepatitis C among inpatients in Georgia's national hospital screening program
Shadaker S , Nasrullah M , Gamkrelidze A , Ray J , Gvinjilia L , Kuchuloria T , Butsashvili M , Getia V , Metreveli D , Tsereteli M , Tsertsvadze T , Link-Gelles R , Millman AJ , Turdziladze A , Averhoff F . Prev Med 2020 138 106153 The country of Georgia initiated an ambitious national hepatitis C elimination program. To facilitate elimination, a national hospital hepatitis C screening program was launched in November 2016, offering all inpatients screening for HCV infection. This analysis assesses the effectiveness of the first year of the screening program to identify HCV-infected persons and link them to care. Data from Georgia's electronic Health Management Information System and ELIMINATION-C treatment database were analyzed for patients aged >/=18 years hospitalized from November 1, 2016 to October 31, 2017. We described patient characteristics and screening results and compared linked-to-care patients to those not linked to care, defined as having a test for viremia following an HCV antibody (anti-HCV) positive hospital screening. Of 291,975 adult inpatients, 252,848 (86.6%) were screened. Of them, 4.9% tested positive, with a high of 17.4% among males aged 40-49. Overall, 19.8% of anti-HCV+ patients were linked to care, which differed by sex (20.6% for males vs. 18.4% for females; p = .019), age (23.9% for age 50-59 years vs. 10.7% for age >/= 70 years; p < .0001), and length of hospitalization (21.8% among patients hospitalized for 1 day vs. 16.1% for those hospitalized 11+ days; p = .023). Redundant screening is a challenge; 15.6% of patients were screened multiple times and 27.6% of anti-HCV+ patients had a prior viremia test. This evaluation demonstrates that hospital-based screening programs can identify large numbers of anti-HCV+ persons, supporting hepatitis C elimination. However, low linkage-to-care rates underscore the need for screening programs to be coupled with effective linkage strategies. |
Blood transfusion safety in the country of Georgia: collateral benefit from a national hepatitis C elimination program

Transfusion 2020 60 (6) 1243-1252 BACKGROUND: In April 2015, the government of Georgia (country) initiated the worldʼs first national hepatitis C elimination program. An analysis of blood donor infectious screening data was conducted to inform a strategic plan to advance blood transfusion safety in Georgia. STUDY DESIGN AND METHODS: Descriptive analysis of blood donation records (2015-2017) was performed to elucidate differences in demographics, donor type, remuneration status, and seroprevalence for infectious markers (hepatitis C virus antibody [anti-HCV], human immunodeficiency virus [HIV], hepatitis B virus surface antigen [HBsAg], and Treponema pallidum). For regression analysis, final models included all variables associated with the outcome in bivariate analysis (chi-square) with a p value of less than 0.05. RESULTS: During 2015 to 2017, there were 251,428 donations in Georgia, representing 112,093 unique donors; 68.5% were from male donors, and 51.2% of donors were paid or replacement (friends or family of intended recipient). The overall seroprevalence significantly declined from 2015 to 2017 for anti-HCV (2.3%-1.4%), HBsAg (1.5%-1.1%), and T. pallidum (1.1%-0.7%) [p < 0.0001]; the decline was not significant for HIV (0.2%-0.1%). Only 41.0% of anti-HCV seropositive donors underwent additional testing to confirm viremia. Infectious marker seroprevalence varied by age, sex, and geography. In multivariable analysis, first-time and paid donor status were associated with seropositivity for all four infectious markers. CONCLUSION: A decline during the study period in infectious markers suggests improvement in blood safety in Georgia. Areas that need further improvement are donor recruitment, standardization of screening and diagnostic follow-up, quality assurance, and posttransfusion surveillance. |

BMC Infect Dis 2020 20 (1) 30 BACKGROUND: Georgia has one of the highest HCV prevalence in the world and launched the world's first national HCV elimination programs in 2015. Georgia set the ambitious target of diagnosing 90% of people living with HCV, treating 95% of those diagnosed and curing 95% of treated patients by 2020. We report outcomes of Sofosbuvir (SOF) based treatment regimens in patients with chronic HCV infection in Georgia. METHODS: Patients with cirrhosis, advanced liver fibrosis and severe extrahepatic manifestations were enrolled in the treatment program. Initial treatment consisted of SOF plus ribavirin (RBV) with or without pegylated interferon (INF). Sustained virologic response (SVR) was defined as undetectable HCV RNA at least 12 weeks after the end of treatment. SVR were calculated using both per-protocol and modified intent-to-treat (mITT) analysis. Results for patients who completed treatment through 31 October 2018 were analyzed. RESULTS: Of the 7342 patients who initiated treatment with SOF-based regimens, 5079 patients were tested for SVR. Total SVR rate was 82.1% in per-protocol analysis and 74.5% in mITT analysis. The lowest response rate was observed among genotype 1 patients (69.5%), intermediate response rate was achieved in genotype 2 patients (81.4%), while the highest response rate was among genotype 3 patients (91.8%). Overall, SOF/RBV regimens achieved lower response rates than IFN/SOF/RBV regimen (72.1% vs 91.3%, P < 0.0001). In multivariate analysis being infected with HCV genotype 2 (RR =1.10, CI [1.05-1.15]) and genotype 3 (RR = 1.14, CI [1.11-1.18]) were associated with higher SVR. Patients with cirrhosis (RR = 0.95, CI [0.93-0.98]), receiving treatment regimens of SOF/RBV 12 weeks, SOF/RBV 20 weeks, SOF/RBV 24 weeks and SOF/RBV 48 weeks (RR = 0.85, CI [0.81-0.91]; RR = 0.86, CI [0.82-0.92]; RR = 0.88, CI [0.85-0.91] and RR = 0.92, CI [0.87-0.98], respectively) were less likely to achieve SVR. CONCLUSIONS: Georgia's real world experience resulted in high overall response rates given that most patients had severe liver damage. Our results provide clear evidence that SOF plus IFN and RBV for 12 weeks can be considered a treatment option for eligible patients with all three HCV genotypes. With introduction of next generation DAAs, significantly improved response rates are expected, paving the way for Georgia to achieve HCV elimination goals. |

Lancet Glob Health 2019 8 (2) e244-e253 BACKGROUND: Georgia has a high prevalence of hepatitis C, with 5.4% of adults chronically infected. On April 28, 2015, Georgia launched a national programme to eliminate hepatitis C by 2020 (90% reduction in prevalence) through scaled-up treatment and prevention interventions. We evaluated the interim effect of the programme and feasibility of achieving the elimination goal. METHODS: We developed a transmission model to capture the hepatitis C epidemic in Georgia, calibrated to data from biobehavioural surveys of people who inject drugs (PWID; 1998-2015) and a national survey (2015). We projected the effect of the administration of direct-acting antiviral treatments until Feb 28, 2019, and the effect of continuing current treatment rates until the end of 2020. Effect was estimated in terms of the relative decrease in hepatitis C incidence, prevalence, and mortality relative to 2015 and of the deaths and infections averted compared with a counterfactual of no treatment over the study period. We also estimated treatment rates needed to reach Georgia's elimination target. FINDINGS: From May 1, 2015, to Feb 28, 2019, 54 313 patients were treated, with approximately 1000 patients treated per month since mid 2017. Compared with 2015, our model projects that these treatments have reduced the prevalence of adult chronic hepatitis C by a median 37% (95% credible interval 30-44), the incidence of chronic hepatitis C by 37% (29-44), and chronic hepatitis C mortality by 14% (3-30) and have prevented 3516 (1842-6250) new infections and averted 252 (134-389) deaths related to chronic hepatitis C. Continuing treatment of 1000 patients per month is predicted to reduce prevalence by 51% (42-61) and incidence by 51% (40-62), by the end of 2020. To reach a 90% reduction by 2020, treatment rates must increase to 4144 (2963-5322) patients initiating treatment per month. INTERPRETATION: Georgia's hepatitis C elimination programme has achieved substantial treatment scale-up, which has reduced the burden of chronic hepatitis C. However, the country is unlikely to meet its 2020 elimination target unless treatment scales up considerably.

J Hepatol 2019 72 (4) 680-687 BACKGROUND & AIMS: Georgia, with a high prevalence of hepatitis C virus (HCV) infection, launched the world's first national hepatitis C elimination program in April 2015. A key strategy is the identification, treatment, and cure of the estimated 150,000 HCV infected persons living in the country. We report on progress and key challenges from Georgia's experience. METHODS: We constructed a care cascade by analyzing linked data from the national hepatitis C screening registry and treatment databases during 2015-2018. We assessed the impact of reflex hepatitis C core antigen (HCVcAg) testing on rates of viremia testing and treatment initiation (i.e. linkage to care). RESULTS: As of December 31, 2018, 1,101,530 adults (39.6% of the adult population) were screened for HCV antibody, of whom 98,430 (8.9%) tested positive, 78,484 (79.7%) received viremia testing, of these, 66,916 persons (85.3%) tested positive for active HCV infection. A total of 52,576 persons with active HCV infection initiated treatment, 48,879 completed their course of treatment. Of the 35,035 who were tested for cure (i.e., sustained virologic response [SVR]), 34,513 (98.5%) achieved SVR. Reflex HCVcAg testing, implemented in March 2018, increased rates of monthly viremia testing among persons screening positive for anti-HCV by 97.5%, however, rates of treatment initiation decreased by 60.7% among diagnosed viremic patients. CONCLUSIONS: Over one-third of persons living with HCV in Georgia have been detected and linked to care and treatment, however, identification and linkage to care of the remaining persons with HCV infection is challenging. Novel interventions, such as reflex testing with HCVcAg can improve rates of viremia testing, but may result in unintended consequences, such as decreased rates of treatment initiation. Linked data systems allow for regular review of the care cascade, allowing for identification of deficiencies and development of corrective actions. |

Clin Infect Dis 2019 71 (5) 1263-1268 BACKGROUND: In April 2015, in collaboration with U.S. CDC and Gilead Sciences, Georgia embarked on the world's first hepatitis C elimination program. We aimed to assess progress towards elimination targets after three years since the beginning of the elimination program. METHODS: We constructed an HCV care cascade for adults in Georgia, based on the estimated 150,000 persons age >/= 18 years with active HCV infection. All patients who were screened or entered the treatment program during April 2015 - March 2018 were included in the analysis. Data on the number of persons screened for HCV was extracted from the national HCV screening database. For treatment component we utilized data from the Georgia National HCV treatment program database. Available treatment options included sofosbuvir (SOF) and ledipasvir/sofosbuvir (LDV/SOF) based regimens. RESULTS: Since April 2015, a cumulative 974,817 adults were screened for HCV antibodies, 86,624 persons tested positive, of which 61,925 underwent HCV confirmatory testing. Among estimated 150,000 adults living with chronic hepatitis C in Georgia, 52,856 (35.1%) were diagnosed, 45,334 (30.2%) initiated treatment with DAA, and 29,090 (19.4%) achieved sustained virologic response (SVR). Overall 37,256 persons were eligible for SVR assessment, of these only 29,620 (79.5%) returned for evaluation. In the per-protocol analysis, SVR rate achieved was 98.2% (29,090/29,620), and 78.1% (29,090/37,256) in the intent-to-treat analysis. CONCLUSIONS: Georgia has made substantial progress in the path towards eliminating hepatitis C. Scaling-up testing and diagnosis, along with effective linkage to treatment services are needed to achieve the goal of elimination. |
Excellence in viral hepatitis elimination - lessons from Georgia
Averhoff F , Lazarus JV , Sergeenko D , Colombo M , Gamkrelidze A , Tsertsvadze T , Butsashvili M , Metreveli D , Sharvadze L , Hellard M , Gnes S , Gabunia T , Nasrullah M . J Hepatol 2019 71 (4) 645-647 Globally, there are more than 70 million people living with chronic hepatitis C virus (HCV) infection, and an estimated 257 million people are living with hepatitis B virus (HBV) infection, both of which cause significant morbidity and mortality primarily as consequences of chronic infection, including hepatocellular carcinoma and liver failure.1 Georgia, a small country in the South Caucasus, has a high prevalence of HCV infection with an estimated 150,000 adults living with hepatitis C, representing 5.4% of the adult population.2 Georgia was the first country in the world to undertake the challenge of hepatitis C elimination. A serosurvey in 2015 laid the foundation for the elimination program; the survey not only defined the burden of hepatitis C in the country, but also identified the major risk factors for transmission (injection drug use and receipt of blood products) and the demographic profile of those infected, thus allowing for clear characterization of the epidemic including identifying the most at-risk populations.2 The cost of treatment in 2015 was prohibitive, so a key partnership was established with Gilead Sciences, who agreed to support the elimination program by providing free-of-charge treatment directly to the country because of the government's commitment to hepatitis C elimination nationwide. |
Progress in testing for and treatment of hepatitis C virus infection among persons who inject drugs - Georgia, 2018
Stvilia K , Spradling PR , Asatiani A , Gogia M , Kutateladze K , Butsashvili M , Zarkua J , Tsertsvadze T , Sharvadze L , Japaridze M , Kuchuloria T , Gvinjilia L , Tskhomelidze I , Gamkrelidze A , Khonelidze I , Sergeenko D , Shadaker S , Averhoff F , Nasrullah M . MMWR Morb Mortal Wkly Rep 2019 68 (29) 637-641 In April 2015, the country of Georgia, with a high prevalence of hepatitis C virus (HCV) infection (5.4% of the adult population, approximately 150,000 persons), embarked on the world's first national elimination program (1,2). Nearly 40% of these infections are attributed to injection drug use, and an estimated 2% of the adult population currently inject drugs, among the highest prevalence of injection drug use in the world (3,4). Since 2006, needle and syringe programs (NSPs) have been offering HCV antibody testing to persons who inject drugs and, since 2015, referring clients with positive test results to the national treatment program. This report summarizes the results of these efforts. Following implementation of the elimination program, the number of HCV antibody tests conducted at NSPs increased from an average of 3,638 per year during 2006-2014 to an average of 21,551 during 2015-2018. In 2017, to enable tracking of clinical outcomes among persons who inject drugs, NSPs began encouraging clients to voluntarily provide their national identification number (NIN), which all citizens must use to access health care treatment services. During 2017-2018, a total of 2,780 NSP clients with positive test results for HCV antibody were identified in the treatment database by their NIN. Of 494 who completed treatment and were tested for HCV RNA >/=12 weeks after completing treatment, 482 (97.6%) were cured of HCV infection. Following the launch of the elimination program, Georgia has made much progress in hepatitis C screening among persons who inject drugs; recent data demonstrate high cure rates achieved in this population. Testing at NSPs is an effective strategy for identifying persons with HCV infection. Tracking clients referred from NSPs through treatment completion allows for monitoring the effectiveness of linkage to care and treatment outcomes in this population at high risk, a key to achieving hepatitis C elimination in Georgia. The program in Georgia might serve as a model for other countries. |
Access to treatment for hepatitis B virus infection - worldwide, 2016
Hutin Y , Nasrullah M , Easterbrook P , Nguimfack BD , Burrone E , Averhoff F , Bulterys M . MMWR Morb Mortal Wkly Rep 2018 67 (28) 773-777 Worldwide, an estimated 257 million persons are living with chronic hepatitis B virus (HBV) infection (1). To achieve the World Health Organization (WHO) goals for elimination of HBV infection worldwide by 2030, defined by WHO as 90% reduction in incidence and 65% reduction in mortality, access to treatment will be crucial. WHO estimated the care cascade* for HBV infection, globally and by WHO Region. The patent and licensing status of entecavir and tenofovir, two WHO-recommended medicines for HBV treatment, were examined using the Medicines Patent Pool MedsPaL(dagger) database. The international price of tenofovir was estimated using WHO's global price reporting mechanism (GPRM), and for entecavir from a published study (2). In 2016, among the estimated 257 million persons infected with HBV worldwide, approximately 27 million (10.5%) were aware of their infection, an estimated 4.5 million (16.7%) of whom were on treatment. In 2017, all low- and middle-income countries (LMICs) could legally procure generic entecavir, and all but two LMICs could legally procure generic tenofovir. The median price of WHO-prequalified generic tenofovir on the international market fell from $208 per year in 2004 to $32 per year in 2016. In 2015, the lowest reported price of entecavir was $427 per year of treatment (2). Increased availability of generic antivirals effective in treating chronic HBV infection has likely improved access to treatment. Taking advantage of reductions in price of antivirals active against HBV infection could further increase access to treatment. Regular analysis of the hepatitis B treatment care cascade can assist in monitoring progress toward HBV elimination goals. |
How well are U.S. primary care providers assessing whether their male patients have male sex partners?
Chavez PRG , Wesolowski LG , Peters PJ , Johnson CH , Nasrullah M , Oraka E , August EM , DiNenno E . Prev Med 2017 107 75-80 Identifying patients at-risk for HIV infection, such as men who have sex with men (MSM), is an important step in providing HIV testing and prevention interventions. It is unknown how primary care providers (PCPs) assess MSM status and related HIV-risk factors. We analyzed data from a panel-derived web-based survey for healthcare providers conducted in 2014 to describe how PCPs in the U.S. determined their patients' MSM status. We calculated adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) to describe PCP characteristics associated with systematically determining MSM status (i.e., PCP used "a patient-completed questionnaire" or "routine verbal review of sex history"). Among the 1008 PCPs, 56% determined MSM status by routine verbal review of sexual history; 41% by patient disclosure; 39% by questions driven by symptoms/history; 23% by using a patient-completed questionnaire, and 9% didn't determine MSM status. PCPs who systematically determined MSM status (n=665; 66%) were more likely to be female (aPR=1.16, CI=1.06-1.26), to be affiliated with a teaching hospital (aPR=1.15, CI=1.06-1.25), to routinely screen all patients aged 13-64 for HIV (aPR=1.29, CI=1.18-1.41), and to estimate that 6% or more of their male patients are MSM (aPR=1.14, CI=1.01-1.30). The majority of PCPs assessed MSM status and HIV risk factors through routine verbal reviews of sexual history. Implementing a systematic approach to identify MSM status and assess risk may allow PCPs to identify more patients needing frequent HIV testing and other preventive services, while mitigating socio-cultural barriers to obtaining such information. |
The role of screening and treatment in national progress toward hepatitis C elimination - Georgia, 2015-2016
Nasrullah M , Sergeenko D , Gvinjilia L , Gamkrelidze A , Tsertsvadze T , Butsashvili M , Metreveli D , Sharvadze L , Alkhazashvili M , Shadaker S , Ward JW , Morgan J , Averhoff F . MMWR Morb Mortal Wkly Rep 2017 66 (29) 773-776 Georgia, a country in the Caucasus region of Eurasia, has a high prevalence of hepatitis C virus (HCV) infection. In April 2015, with technical assistance from CDC, Georgia embarked on the world's first program to eliminate hepatitis C, defined as a 90% reduction in HCV prevalence by 2020 (1,2). The country committed to identifying infected persons and linking them to care and curative antiviral therapy, which was provided free of charge through a partnership with Gilead Sciences (1,2). From April 2015 through December 2016, a total of 27,595 persons initiated treatment for HCV infection, among whom 19,778 (71.7%) completed treatment. Among 6,366 persons tested for HCV RNA ≥12 weeks after completing treatment, 5,356 (84.1%) had no detectable virus in their blood, indicative of a sustained virologic response (SVR) and cure of HCV infection. The number of persons initiating treatment peaked in September 2016 at 4,595 and declined during October-December. Broader implementation of interventions that increase access to HCV testing, care, and treatment for persons living with HCV are needed for Georgia to reach national targets for the elimination of HCV. |
HCV elimination - lessons learned from a small Eurasian country, Georgia
Nasrullah M , Sergeenko D , Gamkrelidze A , Averhoff F . Nat Rev Gastroenterol Hepatol 2017 14 (8) 447-448 In April 2015, in partnership with the US Centers for Disease Control and Prevention and Gilead Sciences, the country of Georgia launched the world's first national HCV elimination programme, aiming to reduce HCV prevalence by 90% by 2020. After 2 years of progress, how can the Georgia experience inform global approaches to eliminating HCV? | In May 2016, the World Health Assembly endorsed the Global Health Sector Strategy on Viral Hepatitis 2016–2021, which calls for the elimination of viral hepatitis as a public health threat by 2030 (a 90% reduction in new infections caused by HBV and HCV infections and a 65% reduction in deaths from these infections)1. An estimated 71 million people have HCV globally, resulting in ∼400,000 deaths annually; most mortality is caused by hepatocellular carcinoma and end-stage liver disease2. The WHO estimates that 1.75 million new HCV infections occurred worldwide in 2015, with wide variations in incidence; transmission mode also varies by country, but the most common modes globally are associated with unsafe health-care practices, followed by injection drug use2. |
Factors associated with condom use among sexually active US adults, National Survey of Family Growth, 2006-2010 and 2011-2013
Nasrullah M , Oraka E , Chavez PR , Johnson CH , DiNenno E . J Sex Med 2017 14 (4) 541-550 BACKGROUND: Condom-less sex can increase the risk of acquiring or transmitting HIV. AIM: To characterize the prevalence of condom use at the most recent sex act and identify factors associated with use of a condom at the most recent sex act in adults in the United States. METHODS: Data from the cross-sectional National Survey of Family Growth from cycles 2006 through 2010 and 2011 through 2013 were analyzed for sexually active men and women 18 to 44 years old who reported having sex (vaginal, anal, or oral) with an opposite-sex partner in the past 12 months. HIV-related sexual risk behaviors (SRBs) in the past 12 months included sex with at least four opposite-sex partners; exchanging sex for money or drugs; sex with an injection drug user; sex with an HIV-positive person; sex with a man who previously had sex with a man (women only); sex with a man (men only); or sex with a partner who had sex with other partners. OUTCOMES: The outcome for this analysis was condom use at the most recent anal or vaginal sex act. RESULTS: Overall prevalence of condom use was 24.8%; only 33.8% of adults with at least one SRB reported the use of a condom. Only 46.4% of unmarried or single men (vs 14.7% married or cohabitating men) and 32.3% unmarried or single women (vs 14.1% married or cohabitating women) with SRBs reported using a condom at the most recent sexual encounter and were less likely to use a condom at the most recent sexual encounter compared with those who did not report SRBs. We did not find a significant relation between using a condom and SRBs in married or cohabitating men and women. STRENGTHS AND LIMITATIONS: Our analysis adds to the literature on how condom use varies by marital status. We measured the use of condoms at the most recent sexual act, which might not reflect an individual's previous behavior of condom use. Nonetheless, condom use at the most recent sexual act has been documented in previous studies as a valid proxy of condom use over time. CONCLUSION: Continued efforts are needed to promote condom use in heterosexual adults in the United States, particularly those at high risk for HIV, namely individuals engaging in anal sexual acts and with multiple sex partners.

Cost-utility of HIV testing programs among men who have sex with men in the United States
Zulliger R , Maulsby C , Solomon L , Baytop C , Orr A , Nasrullah M , Shouse L , DiNenno E , Holtgrave D . AIDS Behav 2016 21 (3) 619-625 Few groups in the United States (US) are as heavily affected by HIV as men who have sex with men (MSM), yet many MSM remain unaware of their infection. HIV diagnosis is important for decreasing onward transmission and promoting effective treatment for HIV, but the cost-effectiveness of testing programs is not well-established. This study reports on the costs and cost-utility of the MSM Testing Initiative (MTI) to newly diagnose HIV among MSM and link them to medical care. Cost and testing data in 15 US cities from January 2013 to March 2014 were prospectively collected and combined to determine the cost-utility of MTI in each city in terms of the cost per Quality Adjusted Life Years (QALY) saved from payer and societal perspectives. The total venue-based HIV testing costs ranged from $18,759 to $564,284 for nine to fifteen months of MTI implementation. The cost-saving threshold for HIV testing of MSM was $20,645 per new HIV diagnosis. Overall, 27,475 men were tested through venue-based MTI, of whom 807 (3 %) were newly diagnosed with HIV. These new diagnoses were associated with approximately 47 averted HIV infections. The cost per QALY saved by implementation of MTI in each city was negative, indicating that MTI venue-based testing was cost-saving in all cities. The cost-utility of social network and couples testing strategies was, however, dependent on whether the programs newly diagnosed MSM. The cost per new HIV diagnosis varied considerably across cities and was influenced by both the local cost of MSM testing implementation and by the seropositivity rate of those reached by the HIV testing program. While the cost-saving threshold for HIV testing is highly achievable, testing programs must successfully reach undiagnosed HIV-positive individuals in order to be cost-effective. This underscores the need for HIV testing programs which target and engage populations such as MSM who are most likely to have undiagnosed HIV to maximize programmatic benefit and cost-utility. |
The association of recent incarceration and health outcomes among HIV-infected adults receiving care in the United States
Nasrullah M , Frazier E , Fagan J , Hardnett F , Skarbinski J . Int J Prison Health 2016 12 (3) 135-44 Purpose The purpose of this paper is to describe factors associated with incarceration as well as the association between recent incarceration and HIV-related sexual risk behaviors, access to insurance, healthcare utilization (emergency department (ED) and hospital use), antiretroviral therapy (ART) prescription, and viral suppression. Design/methodology/approach Using 2009-2010 data from a cross-sectional, nationally representative three-stage sample of HIV-infected adults receiving care in the USA, the authors assessed the demographic characteristics, healthcare utilization, and clinical outcomes of HIV-infected persons who had been recently incarcerated (detention for>24 hours in the past year) using bivariate analyses. The authors used multivariable logistic regression to examine associations of recent incarceration with insurance status as well as clinical and behavioral outcomes. Findings An estimated 22,949 (95 percent confidence interval (CI) 19,062-26,836) or 5.4 percent (CI: 4.7-6.1) of all HIV-infected persons receiving care were recently incarcerated. Factors associated with recent incarceration were age <50 years, being a smoker, having high school diploma or less, being homeless, income at or below the poverty guidelines, having a geometric mean of CD4 count <500 cells/ muL, and using drugs in the past 12 months. Results from multivariable modeling indicated that incarcerated persons were more likely to use ED services, and to have been hospitalized, and less likely to have achieved viral suppression. Originality/value Recent incarceration independently predicted worse health outcomes and greater use of emergency services among HIV-infected adults currently in HIV care. Options to improve the HIV continuum of care, including pre-enrollment for healthcare coverage and discharge planning, may lead to better health outcomes for HIV-infected inmates post-release. |
Acute infections, cost and time to reporting of HIV test results in three U.S. State Public Health Laboratories
Nasrullah M , Wesolowski LG , Ethridge SF , Cranston K , Pentella M , Myers RA , Rudrik JT , Hutchinson AB , Bennett SB , Werner BG . J Infect 2016 73 (2) 164-72 OBJECTIVE: In three U.S. State Public Health Laboratories (PHLs) using a fourth-generation immunoassay (IA), an HIV-1/HIV-2 differentiation antibody IA and a nucleic acid test (NAT), we characterized the yield and time to reporting of acute infections, and cost per positive specimen. METHODS: Routine HIV testing data were collected from July 1, 2012-June 30, 2013 for Massachusetts and Maryland PHLs, and from November 27, 2012-June 30, 2013 for Michigan PHL. Massachusetts and Michigan used fourth-generation and differentiation IAs with NAT conducted by a referral laboratory. In Maryland, fourth-generation IA repeatedly reactive specimens were followed by a Western blot (WB), and those with negative or indeterminate results were tested with a differentiation IA and HIV-1 NAT, and if positive by NAT, confirmed by a different HIV-1 NAT. Specimens from WB-positive persons at risk for HIV-2 were tested with a differentiation IA and, if positive, with an HIV-2 WB and/or differential HIV-1/HIV-2 proviral DNA polymerase chain reaction. RESULTS: Among 7914 specimens from Massachusetts PHL, 6069 from Michigan PHL, and 36,266 from Maryland PHL, 0.10%, 0.02% and 0.05% acute infections were identified, respectively. Massachusetts and Maryland PHLs each had 1 HIV-2 positive specimen. The median time from specimen receipt to laboratory reporting of results for acute infections at Massachusetts, Michigan and Maryland PHLs was 8, 11, and 7 days respectively. The laboratory cost per HIV positive specimen was $336 (Massachusetts), $263 (Michigan) and $210 (Maryland). CONCLUSIONS: Acute and established infections were found by PHLs using fourth-generation IA in conjunction with antibody tests and NAT. Time to reporting of acute HIV test results to clients was suboptimal, and needs to be streamlined to expedite treatment and interrupt transmission. |
Acute infections, cost per infection and turnaround time in three United States hospital laboratories using fourth-generation antigen-antibody human immunodeficiency virus immunoassays
Wesolowski LG , Nasrullah M , Coombs RW , Rosenberg E , Ethridge SF , Hutchinson AB , Dragavon J , Rychert J , Nolte FS , Madory JE , Werner BG . Open Forum Infect Dis 2016 3 (1) ofv188 BACKGROUND: To improve clinical and public health outcomes through early human immunodeficiency virus (HIV) detection, fourth-generation antigen/antibody immunoassay (4IA) and supplemental testing results must be returned rapidly. METHODS: We examined HIV testing data at Harborview Medical Center (HMC), Massachusetts General Hospital (MGH), and the Medical University of South Carolina (MUSC), which used 4IA and supplemental antibody and nucleic acid tests (NATs). At MGH and MUSC, HIV-1 Western blot (WB) and HIV-2 testing were conducted at a reference laboratory. We compared time from specimen collection to laboratory result for established (positive WB) and acute infections (reactive 4IA, negative/indeterminate WB, detectable NAT), and we calculated testing cost per positive-test result. RESULTS: From 3731 (MUSC) to 19 774 (MGH) tests were conducted; 0.01% (MGH) to 0.05% (HMC) were acute infections. Each laboratory had reactive 4IA, WB-negative, or indeterminate specimens without NAT (ie, potential acute infections). Time to result was 1.5 (HMC) to 5.2 days (MGH) for acute and 1.0 (HMC) to 5.2 days (MGH) for established infections. Costs were $1054 (MGH) to $1521 (MUSC). CONCLUSIONS: Conducting supplemental testing in-house lowered turnaround times, which may be further reduced with rapid HIV-1/HIV-2 differentiation tests. Hospitals may benefit from quantitative NATs not requiring physician orders, so all potential acute infections receive NAT. |
Nonvolitional sex and HIV-related sexual risk behaviours among MSM in the United States
Nasrullah M , Oraka E , Chavez PR , Valverde E , Dinenno E . AIDS 2015 29 (13) 1673-80 OBJECTIVE: We estimated the prevalence of lifetime nonvolitional sex (NVS) among MSM by demographic characteristics, and characterized its association with HIV-related sexual risk behaviours among MSM in the United States. DESIGN: The National Survey of Family Growth (NSFG) is a nationally representative cross-sectional survey of the United States. METHODS: NSFG data from recent cycles 2002, and 2006-2010 were weighted and analysed for men aged 18-44 years who reported ever having anal or oral intercourse with another male. Associations of lifetime NVS (forced sex by men or women) and age of first NVS experience (<18 vs. ≥18 years), with HIV-related sexual risk behaviour outcomes in the past 12 months (i.e. sex with two or more male sex partners; exchanged sex for money or drugs; sex with IDU; sex with HIV-positive person; sex with two or more female sex partners) were assessed using adjusted prevalence ratios (aPR). RESULTS: An estimated 3 226 872 or 5.8% of men aged 18-44 years were identified as MSM with 24.6% of them reporting ever experiencing NVS. MSM reporting NVS at age 18 years or older were more likely to have had sex with an IDU [aPR = 4.40; 95% confidence interval (95% CI) 1.78-10.88] and exchanged sex for money or drugs (aPR = 2.52; 95% CI 1.17-5.43) in the past 12 months compared with those not reporting NVS. NVS for MSM less than 18 years of age was associated with exchanging sex for money or drugs. CONCLUSION: Effective interventions to raise awareness of NVS among MSM and to offer support for MSM who have experienced NVS are needed. |
Factors associated with time since last HIV test among persons at high risk for HIV infection, National Survey of Family Growth, 2006-2010
Van Handel M , Lyons B , Oraka E , Nasrullah M , DiNenno E , Dietz P . AIDS Patient Care STDS 2015 29 (10) 533-40 The Centers for Disease Control and Prevention (CDC) recommends annual HIV screening for persons at high risk for HIV infection. We assessed the testing history and factors associated with recent testing (tested in the last 12 months) among persons at high risk for HIV infection. We analyzed 2006-2010 National Survey of Family Growth data and classified respondents aged 15-44 who reported a sexual or drug-use risk behavior in the past year as 'high-risk'. Logistic regression models estimated prevalence ratios assessing the association between demographic and health-related factors and having been recently tested for HIV compared with never been tested. Among high-risk men, 29.3% had recently tested for HIV, 30.7% tested more than 12 months ago, and 40.0% had never been tested. Among high-risk women, 38.0% had recently tested, 36.9% tested more than 12 months ago, and 26.1% had never been tested. Compared with men who were aged 15-19, white, heterosexual, and had not recently visited a doctor, men who were aged 40-44, black/African American, homosexual/gay or bisexual, and had visited a doctor in the past year were more likely to have recently tested. Compared with women who were white, had not recently visited a doctor, and had never been pregnant, women more likely to have recently tested were black/African American, had visited a doctor in the past year, and had been pregnant. Approximately two-thirds of high-risk men and women had not been recently tested for HIV. CDC recommendations for annual screening are not being implemented for the majority of persons at risk. |
