Pattern of linkage and retention in HIV care continuum among patients attending referral HIV care clinic in private sector in India
Abstract and Figures
Continued engagement throughout the HIV care continuum, from HIV diagnosis through retention on antiretroviral therapy (ART), is crucial for enhancing impact of HIV care programs. We assessed linkage and retention in HIV care among people living with HIV (PLHIV) enrolled at a private HIV care clinic in Pune, India. Of 1220 patients, 28% delayed linkage after HIV diagnosis with a median delay of 24 months (IQR = 8-43). Younger people, women, low socioeconomic status, and those diagnosed at facilities other than the study clinic were more likely to delay linkage. Those with advanced HIV disease at diagnosis and testing for HIV due to HIV-related illness were linked to care immediately. Of a total of 629 patients eligible for ART at first CD4 count, 68% initiated ART within 3 months. Among those not eligible for ART, only 46% of patients sought subsequent CD4 count in time. Multivariate logistic regression analysis revealed that patients with initial CD4 count of 350-500 cells/cu mm (OR: 2, 95% CI: 1.1-3.5) and >500 cells/cu mm (OR: 2.1, 95% CI: 1.2-3.7) were less likely to do subsequent CD4 test on time as compared to those with CD4 < 50 cells/cu mm. Among patients not eligible for ART, those having >12 years of education (OR: 0.4, 95% CI: 0.2-0.9) were more likely to have timely uptake of subsequent CD4 count. Among ART eligible patients, being an unskilled laborer (OR: 2.2, 95% CI: 1.1-4.2) predicted lower uptake. The study highlights a long delay from HIV diagnosis to linkage and further attrition during pre-ART and ART phases. It identifies need for newer approaches aimed at timely linkage and continued retention for patients with low education, unskilled laborers, and importantly, asymptomatic patients.

... HIV care clinics in the private sector from India have also noted a long delay from HIV diagnosis to linkage as one of the factors responsible for attrition during not on ART phase. 32 Government of India's free ART programme has introduced the test and treat policy since July 2017 so it might reduce the probability of LFU. It has been reported that policies supporting expansion of ART uptake such as fast-track ART initiation on the day of diagnosis and drug dispensing, differentiated service delivery models for ART and support through health care providers and community stakeholders may improve retention in HIV care. ...
... Lack of association with sex confirms findings of other research, 35,38 although association has been seen in some settings. 34,[39][40][41] Lack of association with formal education level, however, is in contrast to findings by other studies. 6 This may be because of the many years of widespread HIV sensitization programs in Uganda and Kenya, which have increased overall knowledge and awareness about HIV to all regardless of educational level. ...
Introduction
As countries move toward universal HIV treatment, many individuals fail to link to care after diagnosis of HIV. Efficient and effective linkage strategies are needed.
Methods
We implemented a patient-centered, multicomponent linkage strategy in the SEARCH “test-and-treat” trial (NCT 01864603) in Kenya and Uganda. After population-based, community-wide HIV testing, eligible participants were (1) introduced to clinic staff after testing, (2) provided a telephone “hot-line” for enquiries, (3) provided an appointment reminder phone call, (4) given transport reimbursement on linkage, and (5) tracked if linkage appointment was missed. We estimated the proportion linked to care within 1 year and evaluated factors associated with linkage at 7, 30, and 365 days after diagnosis.
Results
Among 71,308 adults tested, 6811 (9.6%) were HIV-infected; of these, 4760 (69.9%) were already in HIV care, and 30.1% were not. Among 2051 not in care, 58% were female, median age was 32 (interquartile range 26–40) years, and median CD4 count was 493 (interquartile range 331–683) cells/µL. Half (49.7%) linked within 1 week, and 73.4% linked within 1 year. Individuals who were younger [15–34 vs. >35 years, adjusted Risk Ratio (aRR) 0.83, 95% confidence interval (CI): 0.74 to 0.94], tested at home vs. community campaign (aRR = 0.87, 95% CI: 0.81 to 0.94), had a high HIV-risk vs. low-risk occupation (aRR = 0.81, 95% CI: 0.75 to 0.88), and were wealthier (aRR 0.90, 95% CI: 0.83 to 0.97) were less likely to link. Linkage did not differ by marital status, stable residence, level of education, or having a phone contact.
Conclusions
Using a multicomponent linkage strategy, high proportions of people living with HIV but not in care linked rapidly after HIV testing.
... Participants who had higher HIV-treatment literacy and who had other health problems were more likely to be retained in care, but these associations lost significance when taking ART status into account. It is common that HIV patients seek care only when they experience symptoms of disease [36], and our results appear to confirm this tendency that participants who are in good health do not seek health care regularly. Our finding also supports the notion that sufficient literacy or knowledge about the benefits of HIV treatment could increase Retention in care of HIV-positive MSM and waria in Indonesia motivation to seek and remain in treatment. ...
Little is known about the prevalence of and factors that influence retention in HIV-related care among Indonesian men who have sex with men (MSM) and transgender women (transwomen, or waria in Indonesian term). Therefore, we explored the driving factors of retention in care among HIV-positive MSM and waria in Indonesia. This cross-sectional study involved 298 self-reported HIV-positive MSM (n = 165) and waria (n = 133). Participants were recruited using targeted sampling and interviewed using a structured questionnaire. We applied a four-step model building process using multivariable logistic regression to examine how sociodemographic, predisposing, enabling, and reinforcing factors were associated with retention in care. Overall, 78.5% of participants were linked to HIV care within 3 months after diagnosis or earlier, and 66.4% were adequately retained in care (at least one health care visit every three months once a person is diagnosed with HIV). Being on antiretroviral therapy (adjusted odds ratio [AOR] = 6.00; 95% confidence interval [CI]: 2.93–12.3), using the Internet to find HIV-related information (AOR = 2.15; 95% CI: 1.00–4.59), and having medical insurance (AOR = 2.84; 95% CI: 1.27–6.34) were associated with adequate retention in care. Involvement with an HIV-related organization was associated negatively with retention in care (AOR = 0.47; 95% CI: 0.24–0.95). Future interventions should increase health insurance coverage and utilize the Internet to help MSM and waria to remain in HIV-related care, thereby assisting them in achieving viral suppression.
... Previous studies about the longitudinal change of retention in care have focused on PLHIV [10][11][12], people who inject drugs or women [8,9,13]. With the exception of a few cross-sectional studies [14,15], men who have sex with men (MSM) have not yet been systematically studied in low and middle income countries. ...
Quantifying HIV service provision along the HIV care continuum is increasingly important for monitoring and evaluating HIV interventions. We examined factors associated with linkage and retention in care longitudinally among MSM (n = 1974, 4933 person-years) diagnosed and living in Guangzhou, China, in 2008–2014. We measured longitudinal change of retention in care (≥2 CD4 tests per year) from linkage and antiretroviral therapy initiation (ART). We examined factors associated with linkage using logistic regression and with retention using generalized estimating equations. The rate of linkage to care was 89% in 2014. ART retention rate dropped from 71% (year 1) to 46% (year 2), suggesting that first-year retention measures likely overestimate retention over longer periods. Lower CD4 levels and older age predicted retention in ART care. These data can inform interventions to improve retention about some subgroups.
... 30 The move to universal coverage of ART further facilitates reaching 90-90-90 HIV treatment service targets because ART initiation is not limited by CD4 levels and people can start treatment on the same day as diagnosis. [31][32][33] However, these linkage-to-treatment strategies that are focused on ART initiation among people who are living with HIV infection should be matched by effective retention strategies. The challenges of achieving sustained engagement in treatment and viral suppression 11,24,34 were affirmed by the results of a large cluster randomized controlled trial conducted in KwaZulu-Natal, South Africa, from 2012 to 2016. ...
Objectives:
The objective of our study was to measure progress toward the UNAIDS 90-90-90 HIV care targets among key populations in urban areas of 2 countries in West Africa: Burkina Faso and Togo.
Methods:
We recruited female sex workers (FSWs) and men who have sex with men (MSM) through respondent-driven sampling. From January to July 2013, 2738 participants were enrolled, tested for HIV, and completed interviewer-administered surveys. We used population-size estimation methods to calculate the number of people who were engaged in the HIV continuum of care.
Results:
HIV prevalence ranged from 0.6% (2 of 329) of MSM in Kara, Togo, to 32.9% (115 of 350) of FSWs in Bobo Dioulasso, Burkina Faso. Of those confirmed to be HIV infected, a range of 0.0% (0 of 2) of MSM in Kara to 55.7% (64 of 115) of FSWs in Bobo Dioulasso were using ART. Based on population estimates, the percentage gap between HIV-infected people who should be using ART (per the 90-90-90 targets) and those who reported using ART ranged from 31.5% among FSWs in Bobo Dioulasso to 100.0% among MSM in Kara.
Conclusions:
HIV service coverage among MSM and FSWs in Burkina Faso and Togo was low in 2013. Interventions for improving engagement of these at-risk populations in the HIV continuum of care should include frequent, routine HIV testing and linkage to evidence-based HIV treatment services. Population-size estimates can be used to inform governments, policy makers, and funding agencies about where elements of HIV service coverage are most needed.
... Many PLHIV detected in the early stage of HIV disease are LTFU and return to care only when symptomatic. 23 In the present study, ART-naïve patients were more likely to default than those already on ART at TB diagnosis; 18% of ARTnaïve patients did not receive ART, and a large proportion (86%) of them had defaulted. Similar findings were reported from public health facilities in Mysore, India, 20 where only 56% of eligible TB patients received ART. ...
SETTING: Little is known about outcomes of patients co-infected with human immunodeficiency virus (HIV) and tuberculosis (TB) who are treated in the private sector in India.
OBJECTIVE: To describe the treatment outcomes of daily anti-tuberculosis treatment (ATT) and their determinants among HIV-TB co-infected patients treated at a private clinic in Pune, India.
DESIGN: Data on adult HIV-TB co-infected patients treated with daily ATT were analysed using logistic regression and Cox model to assess risk factors for default and death.
RESULTS: Of 769 cases, 78% were aged <45 years, 71% were males, 64% had CD4 < 200 cells/mm3, 67% were antiretroviral treatment (ART) naïve at TB diagnosis, 53% had extra-pulmonary TB, and 12% had a past history of TB. ATT was successfully completed by 58.5%, 34.3% defaulted (i.e., discontinued ATT for >2 months) and 3.9% died during ATT. The risk of default was higher among males (aOR 1.67, 95%CI 1.17–2.39), ART-naïve patients (aOR 1.91, 95%CI 1.34–2.73) and those with a past history of TB (aOR 1.86, 95%CI 1.15–3.01). Survival probability at 365 days was 95% (95%CI 93–97). The risk of death was higher among patients with CD4 < 50 cells/mm3 (aHR 4.63, 95%CI 1.47–14.65) than in those with CD4 > 200 cells/mm3.
CONCLUSIONS: Low overall mortality was seen with daily ATT in HIV-TB co-infected patients. High default rates in private facilities warrant urgent attention.
... Most receive a diagnosis at a government ICTC or hospital followed by a referral to an ART center for assessment of treatment eligibility and initiation of free first-line ART. Previous studies in India among general population adults have found approximately 70-80% are linked to ART centers after diagnosis (Alvarez-Uria, 2013;Parchure, Kulkarni, Kulkarni, & Gangakhedkar, 2015;Sarna, Sebastian, Bachani, Sogarwal, & Battala, 2014;Shastri et al., 2013). In our sample of MSM and PWID, we found a comparable number were linked after diagnosis, 80%. ...
UNAIDS set an ambitious target of "90-90-90" by 2020. The first 90 being 90% of those HIV-infected will be diagnosed; the second 90 being 90% of those diagnosed will be linked to medical care and on antiretroviral therapy (ART). While there has been dramatic improvement in HIV testing and ART use, substantial losses continue to occur at linkage-to-care following HIV diagnosis. Data on linkage among men who have sex with men (MSM) and people who inject drugs (PWID) are sparse, despite a greater burden of HIV in these populations. This cross-sectional study was conducted in 27 sites across India. Participants were recruited using respondent-driven sampling and had to be ≥18 years and self-identify as male and report sex with a man in the prior year (MSM) or injection drug use in the prior 2 years (PWID). Analyses were restricted to HIV-infected persons aware of their status. Linkage was defined as ever visiting a doctor for management of HIV after diagnosis. We explored factors that discriminated between those linked and not linked to care using multi-level logistic regression and area under the receiver operating curves (AUC), focusing on modifiable factors. Of 1726 HIV-infected persons aware of their status, 80% were linked to care. Modifiable factors around the time of diagnosis that best discriminated linkage included receiving assistance with HIV medical care (odds ratio [OR]: 10.0, 95% confidence interval [CI]): 5.6-18.2), disclosure of HIV-positive status (OR: 2.8; 95% CI: 2.4-6.1) and receiving information and counseling on management of HIV (OR: 2.3; 95% CI: 1.1-4.6). The AUC for these three factors together was 0.85, higher than other combinations of factors. We identified three simple modifiable factors around the time of diagnosis that could facilitate linkage to care among MSM and PWID in low- and middle-income countries to achieve UNAIDS targets.
... The overwhelming majority of studies focused specifically on how alcohol use affects ART adherence, the step that has previously been of particular interest to many researchers [16]. For most high-income settings, the largest level [76][77][78][79]. The mechanism that mediates the effect of alcohol on ART adherence is widely believed to involve cognition and decision-making: impairment after heavy drinking may lead to forgetfulness about taking one's medications at the appropriate time. ...
Alcohol use is highly prevalent globally with numerous negative consequences to human health, including HIV progression, in people living with HIV (PLH). The HIV continuum of care, or treatment cascade, represents a sequence of targets for intervention that can result in viral suppression, which ultimately benefits individuals and society. The extent to which alcohol impacts each step in the cascade, however, has not been systematically examined. International targets for HIV treatment as prevention aim for 90 % of PLH to be diagnosed, 90 % of them to be prescribed with antiretroviral therapy (ART), and 90 % to achieve viral suppression; currently, only 20 % of PLH are virally suppressed. This systematic review, from 2010 through May 2015, found 53 clinical research papers examining the impact of alcohol use on each step of the HIV treatment cascade. These studies were mostly cross-sectional or cohort studies and from all income settings. Most (77 %) found a negative association between alcohol consumption on one or more stages of the treatment cascade. Lack of consistency in measurement, however, reduced the ability to draw consistent conclusions. Nonetheless, the strong negative correlations suggest that problematic alcohol consumption should be targeted, preferably using evidence-based behavioral and pharmacological interventions, to indirectly increase the proportion of PLH achieving viral suppression, to achieve treatment as prevention mandates, and to reduce HIV transmission.
... These results fall within the range found among other studies in China 39 and globally. [40][41][42] This delay in care may partially be a result of high levels of stigma against HIV-positive individuals, particularly by Chinese health care providers. 43 Furthermore, although two-thirds of HIV-positive individuals were recommended ART, over 12% stopped taking ART, primarily because they considered it too expensive or difficult to take. ...
Differences in risk behaviours between men who have sex with men and men who have sex with both men and women have important implications for HIV and STI transmission. We examined differences in risk behaviours, HIV/STI testing, self-reported HIV/STI diagnoses, and linkage to HIV care between men who have sex with men and men who have sex with both men and women across China.
Participants were recruited through three men who have sex with men-focused websites in China. An online survey containing items on socio-demographics, risk behaviours, testing history, self-reported HIV/STI diagnosis, and linkage to and retention in HIV care was completed from September to October 2014. Chi square tests and logistic regression analyses were conducted.
Men who have sex with both men and women were less likely to use a condom during last anal sex (p ≤ 0.01) and more likely to engage in group sex (p ≤ 0.01) and transactional sex (p ≤ 0.01) compared to men who have sex with men. Self-reported HIV/STI testing and positivity rates between men who have sex with men and men who have sex with both men and women were similar. Among HIV-infected men who have sex with men, there was no difference in rates of linkage to or retention in antiretroviral therapy when comparing men who have sex with men and men who have sex with both men and women.
Chinese men who have sex with men and men who have sex with both men and women may benefit from different HIV and STI intervention and prevention strategies. Achieving a successful decrease in HIV/STI epidemics among Chinese men who have sex with men and men who have sex with both men and women will depend on the ability of targeted and culturally congruent HIV/STI control programmes to facilitate a reduction in risk behaviours.

Objective
Recent UNAIDS ‘90-90-90’ targets propose that to end the HIV epidemic by 2030, 90% of persons living with HIV (PLWH) worldwide should know their diagnosis, 90% of diagnosed PLWH should be on antiretroviral therapy (ART) and 90% of PLWH on ART should be virally suppressed by 2020. We sought to quantify the epidemiological impact of achieving these targets in India.
Methods
We constructed a dynamic-transmission model of the Indian HIV epidemic to project HIV infections and AIDS-related deaths that would occur in India over 15 years. We considered several scenarios: continuation of current care engagement (with early ART initiation), achieving 90-90-90 targets on time and delaying achievement by 5 or 10 years.
Results
In the base case, assuming continuation of current care engagement, we project 794 000 (95% uncertainty range (UR) 571 000–1 104 000) HIV infections and 689 000 (95% UR 468 000–976 000) AIDS-related deaths in India over 15 years. In this scenario, nearly half of PLWH diagnosed would fail to achieve viral suppression by 2030. With achievement of 90-90-90 targets, India could avert 392 000 (95% UR 248 000–559 000) transmissions (48% reduction) and 414 000 (95% UR 260 000–598 000) AIDS-related deaths (59% reduction) compared to the base-case scenario. Furthermore, fewer than 20 000 (95% UR 12 000–30 000) HIV infections would occur in 2030. Delaying achievement of targets resulted in a similar reduction in HIV incidence by 2030 but at the cost of excess overall infections and mortality.
Conclusions
India can halve the epidemiological burden of HIV over 15 years with achievement of the UNAIDS 90-90-90 targets. Reaching the targets on time will require comprehensive healthcare strengthening, especially in early diagnosis and treatment, expanded access to second-line and third-line ART and long-term retention in care.
Introduction
One important operational challenge facing antiretroviral treatment (ART) programmes in low- and middle-income countries is the loss to follow-up between diagnosis of human immunodeficiency virus (HIV) and initiation of ART. This is a major obstacle to achieving universal access to ART. This study from Karnataka, India, tried to measure such losses by determining the number of HIV-positive individuals diagnosed, the number of them reaching ART centres, the number initiated on ART and the reasons for non-initiation of ART.
Methods
A review of records routinely maintained under the National AIDS Control Programme (NACP) was carried out in six districts of Karnataka. HIV-positive persons diagnosed during the months from January to June 2011 in 233 public HIV-testing sites were followed up until December 2011 based on the pre-ART registers. A chi-square test was used to assess statistical significance.
Results
Of 2291 HIV-positive persons diagnosed (52% male; mean age of 35 years), 1829 (80%) reached ART centres. Of the latter, 1166 (64%) were eligible for ART, and 959 (82%) were initiated on treatment. Overall losses (attrition) on the road between HIV diagnosis and ART initiation were 669 (29%). Deaths, migration and not willing to go to the ART centres were cited as the main known reasons for not reaching ART centres. For ART-eligible individuals who did not initiate ART, the most common known reasons for non-initiation included dying before initiation of ART and not being willing to start ART.
Conclusions
In a large state of India, eight in ten HIV-positive persons reached ART centres, and of those found ART eligible, 82% start treatment. Although this is an encouraging achievement, the programme needs to take further steps to improve the current performance by further reducing pre-ART attrition. We recommend online registering of diagnosed HIV-positive patients to track the patients more efficiently.
HIV treatment, care, and support programmes in low- and middle-income countries have traditionally focused more on patients remaining in care after the initiation of antiretroviral therapy (ART) than on earlier stages of care. This study describes the cumulative retention from HIV diagnosis to the achievement of virological suppression after ART initiation in an HIV cohort study in India. Of all patients diagnosed with HIV, 70% entered into care within three months. 65% of patients ineligible for ART at the first assessment were retained in pre-ART care. 67% of those eligible for ART initiated treatment within three months. 30% of patients who initiated ART died or were lost to followup, and 82% achieved virological suppression in the last viral load determination. Most attrition occurred the in pre-ART stages of care, and it was estimated that only 31% of patients diagnosed with HIV engaged in care and achieved virological suppression after ART initiation. The total mortality attributable to pre-ART attrition was considerably higher than the mortality for not achieving virological suppression. This study indicates that early entry into pre-ART care along with timely initiation of ART is more likely to reduce HIV-related mortality compared to achieving virological suppression.
Improving the outcomes of HIV/AIDS treatment programs in resource-limited settings requires successful linkage of patients testing positive for HIV to pre-antiretroviral therapy (ART) care and retention in pre-ART care until ART initiation. We conducted a systematic review of pre-ART retention in care in Africa.
We searched PubMed, ISI Web of Knowledge, conference abstracts, and reference lists for reports on the proportion of adult patients retained between any two points between testing positive for HIV and initiating ART in sub-Saharan African HIV/AIDS care programs. Results were categorized as Stage 1 (from HIV testing to receipt of CD4 count results or clinical staging), Stage 2 (from staging to ART eligibility), or Stage 3 (from ART eligibility to ART initiation). Medians (ranges) were reported for the proportions of patients retained in each stage. We identified 28 eligible studies. The median proportion retained in Stage 1 was 59% (35%-88%); Stage 2, 46% (31%-95%); and Stage 3, 68% (14%-84%). Most studies reported on only one stage; none followed a cohort of patients through all three stages. Enrollment criteria, terminology, end points, follow-up, and outcomes varied widely and were often poorly defined, making aggregation of results difficult. Synthesis of findings from multiple studies suggests that fewer than one-third of patients testing positive for HIV and not yet eligible for ART when diagnosed are retained continuously in care, though this estimate should be regarded with caution because of review limitations.
Studies of retention in pre-ART care report substantial loss of patients at every step, starting with patients who do not return for their initial CD4 count results and ending with those who do not initiate ART despite eligibility. Better health information systems that allow patients to be tracked between service delivery points are needed to properly evaluate pre-ART loss to care, and researchers should attempt to standardize the terminology, definitions, and time periods reported.
Currently, 40% of HIV-infected women enrolled in national prevention of mother-to-child transmission (PMTCT) program in India are loss to follow-up (LTF) before they can receive single dose Nevirapine. To date no study from India has examined the reasons for inadequate utilization of PMTCT services. This study sought to examine the socio-demographic factors associated with LTF of HIV-infected women enrolled during 2002-2008 in a large-scale private sector PMTCT program in Maharashtra, India. Data on HIV-infected women who were enrolled during pregnancy (N=734) and who reported live birth (N=770) were used to analyze factors associated with LTF before delivery and after delivery, respectively. Univariate and multivariate analyses were conducted to estimate the associations between being LTF and socio-demographic factors using generalized linear models. Eighty (10.9%) women were LTF before delivery and 151 (19.6%) women were LTF after delivery. Women with less than graduate level education (RR = 6.32), from a poor family (RR = 1.61), who were registered after 20 weeks of pregnancy (RR = 2.02) and whose partners were HIV non-infected or with unknown HIV status (RR = 2.69) were more likely to be LTF before delivery. Similarly, the significant factors for LTF after delivery were less than graduate level education (RR = 1.82), poor family (RR = 1.42), and registration after 20 weeks of pregnancy (RR = 1.75). This study highlights the need for innovative and effective counseling techniques for less educated women, economic empowerment of women, better strategies to increase uptake of partner's HIV testing, and early registration of women in the program for preventing LTF in PMTCT programs. This need for innovative counseling techniques is even greater for PMTCT programs in the public health sector as the women accessing care in the public sector are likely to be less educated and economically more deprived.
We aimed to analyse treatment outcomes of patients receiving first-line antiretroviral therapy (ART) through the national AIDS control programme of India.
Using routinely collected programme data, we analysed mortality, CD4 evolution and adherence outcomes over a 2-year period in 972 patients who received first-line ART between 1 October 2004 and 31 January 2005 at 3 government ART centres. Cox regression analysis was used to identify independent predictors of mortality.
Of the 972 patients (median age 35 years, 66% men), 71% received the stavudinellamivudine/nevirapine regimen. The median CD4 count of enrolled patients was 119 cells/cmm (interquartile range [IQR] 50-200 cells/ cmm) at treatment initiation; 44% had baseline CD4 count <100 cells/cmm. Of the 927 patients for whom treatment outcomes were available, 71% were alive after 2 years of treatment. The median increase in CD4 count was 1 42 cells/ cmm (IQR 57-750 cells/cmm; n=616) at 6 months and 184 cells/cmm (IQR 102-299 cells/cmm; n=582) at 12 months after treatment. Over 2 years, 124 patients (13%) died; the majority of deaths (68%) occurred within the first 6 months of treatment. Those with baseline CD4 count <50 cells/cmm were significantly more likely to die (adjusted hazard ratio 2.5, 95% confidence interval 1.3-3.2) compared with patients who had baseline CD4 count >50 cells/cmm. Over the 2-year period, 323 patients (35%) missed picking up their monthly drugs at least once and 147 patients (16%) were lost to follow up.
Survival rates of HIV-infected patients on first-line ART in India were comparable with those from other resource-limited countries. Most deaths occurred early and among patients who had advanced disease. Earlier initiation of HIV treatment and improving long term treatment adherence are key priorities for India's ART programme.
Context.
—A high prevalence of human immunodeficiency virus (HIV) infection in female sex workers (FSWs) and men who attend sexually transmitted disease (STD) clinics poses a risk for spread of infection to other populations.Objective.
—To examine spread of HIV to a low-risk population by comparing prevalence of, and risk factors for, HIV and STDs in FSWs and non-FSWs.Methods.
—Women attending STD clinics in Pune, India, were assessed for STDs and HIV from May 13, 1993, to July 11, 1996. Demographic and behavioral information was collected, and clinical and laboratory assessment was performed.Main Outcome Measure.
—Prevalence and risk determinants of HIV infection.Results.
—Of 916 women enrolled, 525 were FSWs and 391 were non-FSWs. Prevalence of HIV in FSWs and non-FSWs was 49.9% and 13.6%, respectively (P<.001). In multivariate analysis, inconsistent condom use and genital ulcer disease or genital warts were associated with prevalent HIV in FSWs. History of sexual contact with a partner with an STD was associated with HIV in non-FSWs.Conclusions.
—Infection with HIV is increasing in non-FSWs, previously thought to be at low risk in India. Since history of sexual contact with their only sex partner was the only risk factor significantly associated with HIV infection, it is likely that these women are being infected by their spouses. This underscores the need for strengthening partner-notification strategies and counseling facilities in India.
Objective:
To estimate the mortality impact of delay in antiretroviral therapy (ART) initiation from the time of entry into care.
Design:
A state-transition Markov process model. This technique allows for assessing mortality before and after ART initiation associated with delays in ART initiation among a general population of ART-eligible patients without conducting a randomized trial.
Methods:
We used patient-level data from 3 South African cohorts to determine transition probabilities for pre-ART CD4 count changes and pre-ART and on-ART mortality. For each parameter, we generated probabilities and distributions for Monte Carlo simulations with 1-week cycles to estimate mortality 52 weeks from clinic entry.
Results:
We estimated an increase in mortality from 11.0% to 14.7% (relative increase of 34%) with a 10-week delay in ART for patients entering care with our pre-ART cohort CD4 distribution. When we examined low CD4 ranges, the relative increase in mortality delays remained similar; however, the absolute increase in mortality rose. For example, among patients entering with CD4 count 50-99 cells per cubic millimeter, 12-month mortality increased from 13.3% with no delay compared with 17.0% with a 10-week delay and 22.9% with a 6-month delay.
Conclusions:
Delays in ART initiation, common in routine HIV programs, can lead to important increases in mortality. Prompt ART initiation for patients entering clinical care and eligible for ART, especially those with lower CD4 counts, could be a relatively low-cost approach with a potential marked impact on mortality.
Background:
Migrant sex workers are known to be vulnerable to HIV. There is substantial female sex worker (FSW) mobility between the borders of Maharashtra and Karnataka, but little programming emphasis on migrant FSWs in India. We sought to understand the individual/cultural, structural, and contextual determinants of migration among FSWs from Karnataka.
Methods:
A cross-sectional face-to-face interview of 1567 FSWs from 142 villages in 3 districts of northern Karnataka, India was conducted from January to June 2008. Villages having 10+ FSWs, a large number of whom were migrant, were selected following mapping of FSWs. Multinomial logistic regression was conducted to identify characteristics associated with migrant (travelled for ≥ 2 weeks outside the district past year) and mobile (travelled for <2 weeks outside the district past year) FSWs; adjusting for age and district.
Results:
Compared with nonmigrants, migrant FSWs were more likely to be brothel than street based (Adjusted Odds Ratio (AOR): 5.7; 95% confidence interval: 1.6-20.0), have higher income from sex work (Adjusted Odds Ratio (AOR): 42.2; 12.6-142.1), speak >2 languages (AOR: 5.6; 2.6-12.0), have more clients (AOR per client: 2.9; 1.2-7.2), and have more sex acts per day (AOR per sex act: 3.5; 1.3-9.3). Mobile FSWs had higher income from sex work (AOR: 13.2; 3.9-44.6) relative to nonmigrants, but not as strongly as for migrant FSWs.
Conclusion:
Out-migration of FSWs in Karnataka was strongly tied to sex work characteristics; thus, the structure inherent in sex work should be capitalized on when developing HIV preventive interventions. The important role of FSWs in HIV epidemics, coupled with the potential for rapid spread of HIV with migration, requires the most effective interventions possible for mobile and migrant FSWs.
To determine retention in HIV care for individuals not yet eligible for antiretroviral therapy (ART) and to explore factors associated with retention in a rural public health HIV program.
HIV-infected adults (≥16 years) not yet eligible for ART, with CD4 cell count >200 cells per microliter from January 2007 to December 2007 were included in the analysis. Retention was defined by repeat CD4 count within 13 months. Factors associated with retention were assessed using logistic regression with clustering at clinic level.
Four thousand two hundred twenty-three were included in the analysis (83.9% female). Overall retention was 44.9% with median time to return 201 days [interquartile range (IQR): 127-274]. Retention by initial CD4 count 201-350, 351-500, and >500 cells per microliter was 51.6% [95% confidence interval (CI): 49.1 to 54.0], 43.2% (95% CI: 40.5 to 45.9), and 34.9% (95% CI: 32.4 to 37.4), respectively. Compared with CD4 201-350 cells per microliter, higher initial CD4 count was significantly associated with lower odds of retention [CD4: 351-500 cells/μL adjusted odds ratio (aOR): 0.72, 95% CI: 0.62 to 0.84; CD4 >500 cells/μL aOR: 0.51, 95% CI: 0.44 to 0.60]. Male sex was independently associated with lower odds (aOR: 0.80, 95% CI: 0.67 to 0.96), and older age with higher odds of retention (for each additional year of age aOR: 1.03, 95% CI: 1.03 to 1.04).
Retention in HIV care before eligibility for ART is poor, particularly for younger individuals and those at an earlier stage of infection. Further work to optimize and evaluate care and monitoring strategies is required to realize the full benefits of the rapid expansion of HIV programs in sub-Saharan Africa.
To compare treatment outcomes by starting CD4 cell counts using data from the Comprehensive International Program of Research on AIDS-South Africa trial.
An observational cohort study.
Patients presenting to primary care clinics with CD4 cell counts below 350 cells/microl were randomized to either doctor or nurse-managed HIV care and followed for at least 2 years after antiretroviral therapy (ART) initiation. Clinical and laboratory outcomes were compared by baseline CD4 cell counts.
Eight hundred and twelve patients were followed for a median of 27.5 months and 36% initiated ART with a CD4 cell count above 200 cells/microl. Although 10% of patients failed virologically, the risk was nearly double among those with a CD4 cell count of 200 cells/microl or less vs. above 200 cells/microl (12.2 vs. 6.8%). Twenty-one deaths occurred, with a five-fold increased risk for the low CD4 cell count group (3.7 vs. 0.7%). After adjustment, those with a CD4 cell count of 200 cells/microl had twice the risk of death/virologic failure [hazard ratio 1.9; 95% confidence interval (CI), 1.1-3.3] and twice the risk of incident tuberculosis (hazard ratio 1.90; 95% CI, 0.89-4.04) as those above 200 cells/microl. Those with either a CD4 cell count of 200 cells/microl or less (hazard ratio 2.1; 95% CI, 1.2-3.8) or a WHO IV condition (hazard ratio 2.9; 95% CI, 0.93-8.8) alone had a two-to-three-fold increased risk of death/virologic failure vs. those with neither, but those with both conditions had a four-fold increased risk (hazard ratio 3.9; 95% CI, 1.9-8.1). We observed some decreased loss to follow-up among those initiating ART at less than 200 cells/microl (hazard ratio 0.79; 95% CI, 0.50-1.25).
Patients initiating ART with higher CD4 cell counts had reduced mortality, tuberculosis and less virologic failure than those initiated at lower CD4 cell counts. Our data support increasing CD4 cell count eligibility criteria for ART initiation.
