Caregivers' experiences of accessing HIV Early Infant Diagnosis (EID) services and its barriers and facilitators, India.

BACKGROUND: India has rolled out Early Infant Diagnosis (EID) program for HIV infection in all states. EID program consists of testing of Infants exposed to HIV periodically over 18 months of age which is a multi-step complex testing cascade. Caregivers represent the primary beneficiary of EID program i.e., infants exposed to HIV and face multiple challenges to access EID services. As part of national EID program outcome assessment study, this study narrates caregivers' perspectives on barriers and facilitators to access and utilize EID services. METHODS: The study was conducted in 31 integrated counselling and testing centres (ICTCs) located in 11 high burden HIV states. A total of 66 in-depth interviews were conducted with caregivers' of infants enrolled in EID program. Thematic analysis was carried out to help identify themes underlying barriers and facilitators to access EID services and utilization from caregivers' perspectives. RESULTS: The stigma and discrimination prevalent in society about HIV remains a key demand side (caregiver-level) barrier. Non-disclosure or selective disclosure of HIV status led to missed or delayed EID tests and delayed HIV diagnosis and initiation of Anti-Retroviral Therapy (ART) for infants exposed to HIV. On supply side (health system-level), accessibility of healthcare facility with EID services was reported as a key barrier. The distance, time and cost were key concerns. Many caregivers faced difficulties to remember the details of complex EID test schedule and relied on a phone call from ICTC counsellor for next due EID test. Delayed EID test results and lack of communication of test results to caregiver were reported as primary barriers for completing the EID test cascade. DISCUSSION: The study reports caregiver-level and health system-level barriers and facilitators for access to EID services from the caregivers' perspectives. While, decentralisation and single window approaches can improve the access, timely communication of test results to the caregiver also need to be built in with appropriate use of technology. A holistic intervention including PLHIV support networks and the peer-led support mechanisms would be useful to address societal factors. CONCLUSION: The study findings have high significance for developing program implementation strategies to improve access and to build right-based and patient-centred EID services.

Augmenting progress on the elimination of vertical transmissions of HIV in India: Insights from Spectrum-based HIV burden estimations.

The government of India has adopted the elimination of vertical transmission of HIV as one of the five high-level goals under phase V of the National AIDS and STD Control Programme (NACP). In this paper, we present the data from HIV estimations 2021 for India and select States detailing the progress as well as the attributable causes for vertical transmissions. The NACP spearheads work on mathematical modelling to estimate HIV burden based on the periodically conducted sentinel surveillance for guiding program implementation and policymaking. Using the results of the latest round of HIV Estimations in 2021, we analysed the mother-to-child transmission (MTCT) during the perinatal and postnatal (breastfeeding) period. In 2021, overall, around 5,000 [3,000-7,800] vertical transmissions were estimated nationally with 58% being perinatal infections and remaining during breastfeeding. MTCT at 6 weeks was around 12.95% [9.45-16.02] with the final transmission rate at 24.25% [18.50-29.50]. Overall, 57% of vertical transmissions were among HIV-positive mothers who did not receive ART during pregnancy or breastfeeding, 19% among mothers who dropped off ART during pregnancy or delivery, and 18% among mothers who were infected during pregnancy or breastfeeding. There were significant variations between States. Depending upon the States, the programme needs to focus on the intervention domains of timely engagement in antenatal care-HIV testing-ART initiation as well as programme retention and adherence support. Equally important would be strengthening the strategic information to generate related evidence for inputting India and State-specific parameters improving the MTCT-related modelled estimates.

Prevalence of HIV among inmates in four states of north India: findings from the 16th round of HIV sentinel surveillance.

PURPOSE: Prisoners are at a higher risk of HIV infection compared to the general population. The purpose of this study is to estimate the prevalence of HIV and related risk behaviours among inmates of the Central Prisons in four states of North India. DESIGN/METHODOLOGY/APPROACH: The HIV sentinel surveillance was conducted in seven Central Prisons in four states of North India from February to April 2019. Four hundred inmates were included from each prison. The interviews were conducted at the Integrated Counselling and Testing Centre located within the prison premises. The Ethics Committee of the National AIDS Control Organization, New Delhi, granted ethical approval before the start of the surveillance. FINDINGS: Overall, 2,721 inmates were enrolled in this study. The mean (SD) age was 38.9 (13.9) years. One-third of prison inmates had comprehensive knowledge about HIV/AIDS. The proportion of convict (54%) and undertrial (46%) inmates was almost equal. The overall prevalence of HIV infection among inmates was 0.96% (95% CI 0.65-1.40). The odds of being HIV positive were significantly higher in never married inmates, undertrials, inmates who were in the prison for more than three months to one year, inmates incarcerated for multiple times, inmates with history of injecting drug use and inmates with history of intercourse with a commercial sex worker. ORIGINALITY/VALUE: The findings from the very first HIV sentinel surveillance in central prisons in North India have been presented in this paper. This has huge implications for future policy decisions.

Low awareness but high acceptability of pre-exposure prophylaxis for HIV among men who have sex with men and transgender persons in Delhi, India.

Background: HIV pre-exposure prophylaxis (PrEP) is part of India's HIV prevention policy. We aimed to determine awareness of and willingness-to-use PrEP among men-who-have-sex-with-men (MSM) and transgender-persons (TG) in Delhi, India.Methods: A cross-sectional study was conducted at five purposively selected targeted-intervention projects in Delhi. Participants included self-identified MSM/TG aged ≥18 years, with negative/unknown HIV serostatus. A structured interview schedule, developed using formative research, was used. Primary outcomes were awareness of, and willingness-to-use PrEP. Socio-demographic and behaviour variables included age, living situation, education, anal-sex, condom-use and experiences of physical-violence. Determinants of outcome were identified in univariable logistic regression; variables associated at p < .25 were included in multivariable regression models.Results: Of 400 (224 MSM, 176 TG), mean ± SD age 25.7 ± 7.2 years, 14.5% (95% CI 11.0, 18.0) were aware of PrEP, while 63.3% (95% CI: 58.6, 68.1) reported willingness-to-use PrEP. PrEP-awareness was independently associated with formal-education (adjusted odds ratio; AOR = 1.20), professional occupation (AOR = 5.45) and condom-use (AOR = 3.07). Willingness-to-use PrEP was higher if participants had recent anal-sex (AOR = 2.29), had used condoms during anal-sex (AOR = 2.09), or recently experienced physical-violence (AOR = 3.65).Conclusions: PrEP awareness was low, but most were willing to use PrEP, implying that communication is key to PrEP awareness and uptake.

Exploring access to HIV-related services and programmatic gaps for Men having Sex with Men (MSM) in rural India- a qualitative study.

BACKGROUND: Despite the Link Worker Scheme to address the HIV risk and vulnerabilities in rural areas, reaching out to unreached men having sex with men (MSM) remains a challenge in rural India. This study explored issues around health care access and programmatic gaps among MSM in rural settings of India. METHODS: We conducted eight Focused Group Discussions (FGDs), 20 Key Informant Interviews (KIIs), and 20 In-Depth Interviews (IDIs) in four rural sites in Maharashtra, Odisha, Madhya Pradesh, and Uttar Pradesh between November 2018 and September 2019. The data in the local language were audio-recorded, transcribed, and translated. Data were analyzed in NVivo version 11.0 software using the grounded theory approach. RESULTS: Primary barriers to health care access were lack of knowledge, myths and misconceptions, not having faith in the quality of services, program invisibility in a rural setting, and anticipated stigma at government health facilities. Government-targeted intervention services did not seem to be optimally advertised in rural areas as MSM showed a lack of information about it. Those who knew reported not accessing the available government facilities due to lack of ambient services, fear of the stigma transforming into fear of breach of confidentiality. One MSM from Odisha expressed, "…they get fear to go to the hospital because they know that hospital will not maintain confidentiality because they are local people. If society will know about them, then family life will be disturbed" [OR-R-KI-04]. Participants expressed the desire for services similar to those provided by the Accredited Social Health Activists (ASHA), frontline health workers for MSM. CONCLUSION: Programme invisibility emerges as the most critical issue for rural and young MSM. Adolescent and panthis emerged as Hidden MSM and they need focused attention from the programme. The need for village-level workers such as ASHA specifically for the MSM population emerged. MSM-friendly health clinics would help to improve healthcare access in rural MSMs under Sexual and Reproductive Health Care.

Determinants of Turn-Around-Time for Early Infant Diagnosis of HIV Testing: Retrospective Analysis of National Level PCR Testing Data.

India has been implementing one of the biggest Early Infant Diagnosis (EID) of HIV intervention globally. The turn-around-time (TAT) for EID test is one of the major factors for success of the program. This study was to assess the turnaround time and its determinants. It is a mixed methods study with quantitative analysis of retrospective data (2013-2016) collected from all the 7 Early Infant Diagnosis testing laboratories (called as regional reference laboratories or RRLs) in India and qualitative component that can help explain the determinants of turn-around-time. The retrospective national level data available from the RRLs was analyzed to measure the turn-around-time from the receipt of samples to the dispatch of results and to understand the determinants for the same. The 3 components transport time, testing time, and dispatch time were also calculated. Transport time was analyzed state-wise and the testing time RRL wise to understand disparities, if any. Qualitative interviews with the RRL officials were conducted to understand the underlying determinants of TAT. The Median turn-around-time ranged between 29 and 53 days over the 4 years. Transport time was significantly higher for states without RRL (42 days) than those with RRL (27 days). Testing time varied from RRL to RRL and was associated with incomplete forms, inadequate samples, kits logistics, staff turnover, staff training, and instrument related issues. The TAT is high and can be potentially reduced with interventions, such as decentralization of RRLs; courier systems for sample transport; and ensuring adequate resources at the RRL level.

Impact of COVID-19 Pandemic on HIV Testing Uptake Among Key Populations Enrolled in Targeted Intervention Program in Maharashtra, India.

The COVID-19 pandemic posed unprecedented challenges to HIV services globally. We evaluated the impact of the COVID-19 pandemic on the uptake of HIV testing in the Targeted Intervention (TI) program in Maharashtra-a high HIV burden state in India. Annual HIV testing was sustained during the pandemic year (2020-2021), at levels similar to the pre-pandemic year (2019-2020), among Female Sex Workers (FSW), Men having Sex with Men (MSM), Transgender (TG), and Truckers; but not among Migrants and Intravenous Drug Users (IDU). There was an acute decline during the lockdown across all typologies. Sharp recovery was seen among FSW, MSM, and TG during the early months of the un-lockdown. The community-based screening (CBS) approach primarily contributed to this recovery. Among migrants and truckers, recovery was delayed. There was an overall reduction of 58% in annual HIV-positive registrations. The community-based networks, participatory structures, and processes of HIV programs played an essential role in reaching the community during the pandemic.

Prevalence and determinants of heterosexual anal-intercourse among female sex workers in India: Findings from nationwide cross-sectional biological and behavioural survey.

BACKGROUND: The vulnerability of female sex workers (FSWs) to HIV infection increases if unprotected heterosexual anal intercourse (HAI) is practiced. OBJECTIVES: To estimate the prevalence of HAI among FSWs, and associated factors, and prevalence of consistent condom use (CCU) during HAI and associated factors. METHODS: Analysis of cross-sectional data from nationwide biological and behavioural survey, conducted at 73 randomly selected domains with sample size of 27,000 in India. RESULTS: A total of 25,932 FSWs were included in the analysis, after excluding 1075 (3.9%) FSWs for which the data were incomplete. The prevalence of HAI was 29.9% (95% CI, 29.3, 30.4); The CCU during HAI in the last one month was 58.9%. Younger age at the start of sex work, use of mobile phone/internet for soliciting client, home as a place of sex work, consumption of alcohol/drug, and physical violence against FSWs were associated with higher odds of HAI. Frequent contact with outreach workers, awareness of sexually transmitted infection, and older age at the start of sex work was associated with CCU. CONCLUSION: Prevalence of HAI was high among FSW in India. The national program could target those factors that reduce the odds of HAI and/or promote CCU.

Socio-demographic and behavioural determinants of HIV prevalence among homosexual and bisexual men having sex with men (MSM) in India: Integrated bio-behavioural surveillance.

Background: HIV prevalence among men who have sex with men (MSM) is 16.5 times higher than adult HIV prevalence. With a socio-cultural context that demands marriage, a considerable proportion of MSM in India have female sexual partners and act as a bridge population. Stratified analysis of HIV risk factors among homosexual and bisexual MSM will be instrumental in identifying the high-risk MSM. We aim to identify the socio-demographic and behavioural factors associated with HIV risk among homosexual and bisexual MSM. Methods: Overall, 23081 MSM were enrolled in the IBBS conducted across India between October 2014 and November 2015. Data and blood samples were collected. Chi-square test, univariate and multivariable logistic regression methods were used in data analysis. Results: HIV prevalence was significantly higher among homosexual MSM than bisexual MSM. Older age, lesser education, being a sex worker, being married, living with a male or hijra partner, younger age at initiation of MSM behaviour, duration, injecting drugs, and having STI symptoms were associated with higher prevalence. The prevalence of new homosexual MSM was 11.4%. Nearly 75% of the bisexual MSM reported inconsistent condom usage with female partners. Conclusion: Interventions for early identification of new MSM and advocacy for safe sex with alternative preventive techniques are recommended.

Spatial heterogeneity of risk factors associated with HIV prevalence among men who inject drugs in India: An analysis of the data from the integrated bio-behavioral surveillance, India.

People who inject drugs (PWID) are India's third-largest vulnerable population to human immunodeficiency virus (HIV) infection. PWID in India are confined to certain geographic locations and exhibit varying injecting and sexual risk behaviors, contributing considerably to increasing HIV trends in specific regions. Spatial heterogeneity in risk factors among vulnerable PWID influences HIV prevalence, transmission dynamics, and disease management. Stratified analysis of HIV prevalence based on risk behaviors and geographic locations of PWID will be instrumental in strategic interventions. To stratify the male PWID based on their risk behaviors in each state and determine the HIV prevalence for each stratum. The behavioral data and HIV prevalence of the national integrated biological and behavioural surveillance (IBBS), a nationwide cross-sectional community-based study conducted in 2014 to 2015, was analyzed. Data from 19,902 men who inject drugs across 53 domains in 29 states of India were included. Women who inject drugs were excluded at the time of IBBS, and hence PWID in this study refers to only men who inject drugs. PWID were categorized based on their risk profile, and the corresponding HIV prevalence for each state was determined. HIV prevalence was the highest (29.6%) in Uttar Pradesh, with a high prevalence of risk behaviors among PWID. High HIV prevalence ranging between 12.1% and 22.4% was observed in a few states in East and North-East India and most states in central and North India. Unsafe injecting and sexual practices were significantly (P < .05) associated with higher HIV prevalence and more significantly in National Capital Territory of Delhi (P < .001). Unsafe injecting practices among PWID were proportionally higher in Western and Central India, whereas unsafe sexual behaviors were widespread among most states. Unsafe sexual practices among male PWID were common. The high prevalence of unsafe injecting had significant HIV infection and transmission risks in Western and Central India. The results emphasize the need for stratified, region-specific interventions and combination approaches for harm reduction among PWID. Strengthening the measures that facilitate the reduction of high-risk behaviors, adoption of safe practices, and utilization of HIV services will positively impact HIV prevention measures among PWID.

Injecting drug use & HIV prevalence among female sex workers: Evidence from the National Integrated Biological & Behavioural Surveillance, India.

Background & objectives: Female sex workers (FSWs) who inject drugs (FSW-IDs) have a higher risk of HIV infection and transmission. Understanding the socio-demographic characteristics and other risk behaviours among FSW-IDs will help in strengthening targeted interventions for HIV prevention and management. In the present study, the HIV prevalence, associated socio-demographic characteristics and risk behaviours among FSWs who injected drugs (FSW-IDs) and those who did not ID (FSW-NIDs) was determined in India. Methods: The national cross-sectional, community-based, integrated biological and behavioural surveillance was conducted in 2014-2015 at 73 randomly selected FSW domains across 28 States and Union Territories in India. The sample size was fixed at 400 for each domain, and a probability-based sampling method was followed. The data were analyzed by logistic regression methods. Results: Data from 27,007 FSWs were included in the analysis, of which 802 (3%) were FSW-IDs. HIV prevalence among FSW-IDs was significantly higher than that in FSW-NIDs (4.5 vs. 1.9%). Univariate analysis showed that factors significantly associated with higher HIV prevalence among FSW-IDs were older age, sex work as the only source of income, dissolved marriage, living with a sex worker, urban locality of sex work and consumption of alcohol or oral drugs. In multivariable analysis, factors such as older age of FSW-IDs (35 yr and above), having a dissolved marriage and sex work being the only source of income were observed to be independently and significantly associated with higher HIV prevalence. Interpretation & conclusions: Scaling up the HIV preventive interventions for FSW-IDs, such as facilitating awareness and improved access to needle and syringe exchange programme (NSEP) and opioid substitution therapy (OST), encouraging safe sex and injecting practices, educating on the harmful effects of alcohol and drugs and providing alternative vocation options to secure their financial needs are several strategies that may reduce HIV transmission among FSWs.

Diversity in HIV epidemic transitions in India: An application of HIV epidemiological metrices and benchmarks.

BACKGROUND: The Joint United Nations Programme on AIDS (UNAIDS) has emphasized on the incidence-prevalence ratio (IPR) and incidence-mortality ratio (IMR) to measure the progress in HIV epidemic control. In this paper, we describe the status of epidemic control in India and in various states in terms of UNAIDS's recommended metrices. METHOD: The National AIDS Control Programme (NACP) of India spearheads work on mathematical modelling to estimate HIV burden based on periodically conducted sentinel surveillance for providing guidance to program implementation and policymaking. Using the results of the latest round of HIV Estimations in 2019, IPR and IMR were calculated. RESULTS: National level IPR was 0.029 [0.022-0.037] in 2019 and ranged from 0.01 to 0.15 in various States and Union Territories (UTs). Corresponding Incidence-Mortality Ratio was at 0.881 [0.754-1.014] nationally and ranged between 0.20 and 12.90 across the States/UTs. CONCLUSIONS: Based on UNAIDS recommended indicators for HIV epidemic control, namely IPR and IMR; national AIDS response in India appears on track. However, the program success is not uniform and significant heterogeneity as well as expanding epidemic was observed at the level of States or UTs. Reinforcing States/UTs specific and focused HIV prevention, testing and treatment initiatives may help in the attainment of 2030 Sustainable Development Goals of ending AIDS as a public health threat by 2030.

The clinical demand and supply of blood in India: A National level estimation study.

BACKGROUND: Estimating the clinical demand for blood and components arising in a health facility is crucial to ensure timely availability of blood. This study aims to estimate disease-specific clinical demand, supply and utilization of whole blood and components in India. METHODS: We conducted a national level cross-sectional study in five randomly selected states from five regions of the country. We included 251 public and private facilities representing primary, secondary and tertiary care facilities. We collected annual disease-specific demand, supply and utilization of blood and components using a structured tool. We estimated the national demand by extrapolating the study data (demand and beds) to the total number of estimated beds in the country. FINDINGS: According to the study, the total clinical demand of 251 health facilities with 51,562 beds was 474,627 whole blood units. Based on this, the clinical demand for India was estimated at 14·6 million whole blood units (95 CI: 14·59-14·62), an equivalent of 36·3 donations per 1,000 eligible populations, which will address whole blood and component requirement. The medicine specialty accounted for 6·0 million units (41·2%), followed by surgery 4·1 million (27·9%), obstetrics and gynecology 3·3 million (22·4%) and pediatrics 1·2 million (8·5%) units. The supply was 93% which is equivalent to 33·8 donations against the demand. CONCLUSION: The study indicated a demand and supply gap of 2.5 donations per 1,000 eligible persons which is around one million units. The gap emphasises the need for sustained and concerted efforts from all stakeholders and for increasing the awareness about repeat voluntary non-remunerated blood donation (VNRBD); optimizing the availability of blood components through efficient blood component separation units; promoting modern principles of patient blood management and strengthening capacities of human resources in the blood transfusion system in India.

Syndemic violence victimization, alcohol and drug use, and HIV transmission risk behavior among HIV-negative transgender women in India: A cross-sectional, population-based study.

Transgender women globally are disproportionately burdened by HIV. Co-occurring epidemics of adverse psychosocial exposures accelerate HIV sexual risk, including among transgender women; however, studies using additive models fail to examine synergies among psychosocial conditions that define a syndemic. We examined the impact of synergistic interactions among 4 psychosocial exposures on condomless anal sex (CAS) among transgender women in India. A national probability-based sample of 4,607 HIV-negative transgender women completed the Indian Integrated Biological and Behavioural Surveillance survey, 2014-2015. We used linear probability regression and logistic regression to assess 2-, 3-, and 4-way interactions among 4 psychosocial exposures (physical violence, sexual violence, drug use, and alcohol use) on CAS. Overall, 27.3% reported physical and 22.3% sexual violence victimization (39.2% either physical or sexual violence), one-third (33.9%) reported frequent alcohol use and 11.5% illicit drug use. Physical violence was associated with twofold higher odds of CAS in the main effects model. Statistically significant two- and three-way interactions were identified, on both the multiplicative and the additive scales, between physical violence and drug use; physical and sexual violence; physical violence, sexual violence, and alcohol use; and physical violence, alcohol use and drug use. Physical and sexual violence victimization, and alcohol and drug use are highly prevalent and synergistically interact to increase CAS among HIV-negative transgender women in India. Targeted and integrated multilevel initiatives to improve the assessment of psychosocial comorbidities, to combat systemic transphobic violence, and to provide tailored, trauma-informed alcohol and substance use treatment services may reduce HIV risk among transgender women.

Comparison of prevention of parent-to-child HIV transmission programme & national biennial HIV sentinel surveillance data for tracking HIV epidemic in India.

Background & objectives: HIV sentinel surveillance (HSS) among antenatal women in India has been used to track the epidemic for many years. However, reliable tracking at the local level is not possible as ANC sentinel sites are limited in number and cover a smaller sample size at each site. Prevention of parent-to-child-transmission (PPTCT) programme data has a potential advantage due to better geographical coverage, which could provide more precise HIV case estimates; therefore, we compared HSS ANC data with PPTCT programme data for HIV tracking. Methods: Out of the 499 surveillance sites, where HSS and PPTCT programme was being conducted in 2015, 210 sites (140 urban and 70 rural) were selected using a stratified random sampling method. HSS (n=72,981) and PPTCT (n=112,832) data records were linked confidentially. The sociodemographic characteristics of HSS and PPTCT attendees were compared. HIV prevalence from HSS ANC was compared with the PPTCT programme data using Chi-square test. State- and site-level correlation of HIV prevalence was also done. Concordance between HSS and PPTCT HIV positivity was estimated using kappa statistics. Results: The age distribution of HSS and PPTCT attendees was similar (range: 23 to 27 yr); however, HSS ANC participants were better educated, whereas PPTCT recorded a higher proportion of homemakers. The correlation of HIV prevalence between HSS and PPTCT was high (r=0.9) at the State level and moderate at the site level (r=0.7). The HIV positivity agreement between HSS ANC and PPTCT was good (kappa=0.633). A similar prevalence was reported across 26 States, whereas PPTCT had a significantly lower prevalence than HSS in three States where PPTCT coverage was low. Overall HIV prevalence was 0.31 per cent in HSS and 0.22 per cent in PPTCT (P<0.001). Interpretation & conclusions: High-quality PPTCT programme data can provide reliable HIV trends in India. An operational framework for PPTCT-based surveillance should be pilot-tested in a phased manner before replacing HSS with PPTCT.

Assessment of Performance of Blood Banks in India: A National Level Cross Sectional Study.

India lacks comprehensive information about blood transfusion systems, which could help ensure universal access to safe blood through evidence-based strategies and programs. We conducted the first national assessment of blood bank systems, services, practices, and performance in India. We conducted a cross-sectional survey of all 2626 blood banks and assessed the administrative, technical, and quality aspects in 2016. In addition to descriptive analysis, we compared the means of different variables using independent t-test or ANOVA and a generalized linear model. We performed linear regression analysis between the collection of blood per 100 people and the number of blood banks per million people. The disaggregated mean score of quality management system and overall performance are presented by different groups. Besides, we graded the performance based on tertile classification, as low, medium and high-performance blood banks. Of the 2493 blood banks that participated in the study, most were public (38%) or not-for-profit(38%), and 51% had component separation facilities. Of the 11.65 million units of blood collected annually, 72% was through voluntary blood donation. There were 2.2 blood banks per one million people, collecting around one unit per 100 persons annually with wide variation between states. The mean overall performance score was 62(95% confidence interval [CI]:61.6-62.5), and the mean quality management system score was 57.4(95% CI:56.8-58.0), with significant variation across different categories of blood banks. This assessment provides critical information for developing evidence-based policies, programs, and monitoring systems to improve the performance of blood transfusion services in India.

An Analysis of Levels and Trends in HIV Prevalence Among Pregnant Women Attending Antenatal Clinics in Karnataka, South India, 2003-2019.

BACKGROUND AND OBJECTIVE: Periodic tracking of the trends and the levels of HIV prevalence at regional and district levels helps to strengthen a state's HIV/AIDS response. HIV prevalence among pregnant women is crucial for the HIV prevalence estimation of the general population. Karnataka is one of the high HIV prevalence states in India. Probing regional and district levels and trends of HIV prevalence provides critical insights into district-level epidemic patterns. This paper analyzes the region- and district-wise levels and trends of HIV prevalence among pregnant women attending the antenatal clinics (ANC) from 2003 to 2019 in Karnataka, South India. METHODS: HIV prevalence data collected from pregnant women in Karnataka during HIV Sentinel Surveillance (HSS) between 2003 and 2019 was used for trend analysis. The consistent sites were grouped into four zones (Bangalore, Belgaum, Gulbarga and Mysore regions), totaling 60 sites, including 30 urban and 30 rural sites. Regional and district-level HIV prevalence was calculated; trend analysis using Chi-square trend test and spatial analysis using QGIS software was done. For the last three HSS rounds, HIV prevalence based on sociodemographic variables was calculated to understand the factors contributing to HIV positivity in each region. RESULTS: In total, 254,563 pregnant women were recruited. HIV prevalence in Karnataka was 0.22 (OR: 0.15 95% CI: 0.16 - 0.28) in 2019. The prevalence was 0.24, 0.32, 0.17 and 0.14 in Bangalore, Belgaum, Gulbarga, and Mysore regions, respectively. HIV prevalence had significantly (P< 0.05) declined in 26 districts. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: HIV prevalence among pregnant women was comparatively higher in Bangalore and Belgaum regions. Analysis of contextual factors associated with the transmission risk and evidence-based targeted interventions will strengthen HIV management in Karnataka. Regionalized, disaggregated, sub-national analyses will help identify emerging pockets of infections, concentrated epidemic zones and contextual factors driving the disease transmission.

Young and invisible: a qualitative study of service engagement by people who inject drugs in India.

OBJECTIVES: The HIV epidemic in India is concentrated in key populations such as people who inject drugs (PWID). New HIV infections are high among young PWID (≤30 years of age), who are hard to engage in services. We assessed perspectives of young PWID to guide development of youth-specific services. SETTING: We conducted focus group discussions (FGDs) with PWID and staff at venues offering services to PWID in three Indian cities representing historical and emerging drug use epidemics. PARTICIPANTS: PWID were eligible to participate if they were between 18 and 35 years, had initiated injection as adolescents or young adults and knew adolescent PWID in their networks. 43 PWID (81% male, 19% female) and 10 staff members participated in FGDs. A semistructured interview guide was used to elicit participants' narratives on injection initiation experiences, barriers to seeking harm reduction services, service delivery gaps and recommendations to promote engagement. Thematic analysis was used to develop an explanatory model for service engagement in each temporal stage across the injection continuum. RESULTS: Injection initiation followed non-injection opioid dependence. Lack of services for non-injection opioid dependence was a key gap in the preinjection initiation phase. Lack of knowledge and reliance on informal sources for injecting equipment were key reasons for non-engagement in the peri-injection phase. Additionally, low-risk perception resulted in low motivation to seek services. Psychosocial and structural factors shaped engagement after established injection. Housing and food insecurity, and stigma disproportionately affected female PWID while lack of confidential adolescent friendly services impeded engagement by adolescent PWID. CONCLUSIONS: Development of youth-specific services for young PWID in India will need to address unique vulnerabilities and service gaps along each stage of the injection continuum. Scaling-up of tailored services is needed for young female PWID and adolescents, including interventions that prevent injection initiation and provision of confidential harm reduction services.

District-level HIV estimates using the spectrum model in five states of India, 2017.

ABSTRACT: Decentralized response has been the hallmark of the National AIDS Control Programme in India. District-level HIV burden estimates quantifying the distribution of the epidemics are needed to enhance this decentralized response further to monitor the progress on prevention, testing, and treatment interventions. In this paper, we describe the methodology and results of district-level estimates using the Spectrum model piloted in 5 states of India under National AIDS Control Programme.Using state spectrum model for HIV estimations 2017, we disaggregated state results by the district in pilot states. Each district was considered a subepidemic and HIV epidemic configuration was carried out in its general population as well as in key population. We used HIV surveillance data from antenatal clinics and routine pregnant women testing to model the general population's epidemic curve. We used HIV prevalence data available from HIV sentinel surveillance and integrated biological and behavioral surveys to inform the epidemic curve for key population. Estimation and projection packgage classic platform was used for the curve fitting. District-wide estimates extracted from subpopulation summary in Spectrum results section were used to calculate relative burden for each district and applied to approved State HIV Estimations 2017 estimates.No district in Tamil Nadu had an adult HIV prevalence of higher than 0.5% except for one, and the epidemic seems to be declining. In Maharashtra, the epidemic has shown a decline, with all except 5 districts showing an adult prevalence of less than 0.50%. In Gujarat and Uttar Pradesh, few districts showed rising HIV prevalence. However, none had an adult prevalence of higher than 0.50%. In Mizoram, 6 of 8 districts showed a rising HIV trend with an adult prevalence of 1% or more in 5 districts.Disaggregation of state-level estimates by districts provided insights on epidemic diversity within the analyzed states. It also provided baseline evidence to measure the progress toward the goal of end of AIDS by 2030.

A national level estimation of population need for blood in India.

BACKGROUND: The population need for blood is the total volume required to transfuse all the individuals who need transfusion in a defined population over a defined period. The clinical demand will arise when people with a disease or condition who require transfusion, access healthcare services, and subsequently the clinicians request blood. Essentially, the conversion of need to demand must be maximum to avoid preventable mortality and morbidity. The study estimated the population need for blood in India. METHODS: The methodology included a comprehensive literature review to determine the diseases and conditions requiring transfusion, the population at risk, and prevalence or incidence; and Delphi method to estimate the percentage of people requiring transfusion, and the quantum. RESULTS: The estimated annual population need was 26.2 million units (95% CI; 17.9-38.0) of whole blood to address the need for red cells and other components after the separation process. The need for medical conditions was 11.0 million units (95% CI:8.7-14.7), followed by surgery 6.6 million (95% CI:3.8-10.0), pediatrics 5.0 million (95% CI:3.5-7.0), and obstetrics and gynecology 3.6 million units (95% CI:1.9-6.2). The gap between need and demand which depends upon the access and efficiency of healthcare service provision was estimated at 13 million units. CONCLUSION: The study brings evidence to highlight the gap between need and demand and the importance of addressing it. It cannot be just the responsibility of blood transfusion or health systems, it requires a multi-sectoral approach to address the barriers affecting the conversion of need to clinical demand for blood.
