Barriers Contributing to Loss to Follow-up among HIV-patients in Limpopo Province, South Africa: Patients’ and Nurses’ Perspectives

Background: Antiretroviral therapy is a lifelong commitment that requires patients to adhere to their daily medication dose schedules and make frequent visits to health services for their care. People living with HIV can live healthy long lives when retained on antiretroviral therapy. Retention in care has been identified as the benchmark in the HIV Care Continuum, where most people living with HIV fail. Interventions are urgently needed to address this benchmark to achieve the worldwide 95-95-95 goals. Despite the South African government`s efforts to expand access to antiretroviral therapy services from urban centers to resource-constrained rural communities, there were 140,000 HIV- related deaths in 2014 and 85,796 HIV- related deaths in 2021. Patients have become lost to follow-up, putting their health and that of their communities at risk. Moreover, the loss of follow-up care among HIV-positive people who are on antiretroviral treatment continues to be a significant problem. The study determined barriers contributing to the Loss of follow-up rates among people living with HIV. Methods: A qualitative research study was conducted; Non-probability purposive sampling was used to select eight nurses from clinics with the highest and lowest loss-to-follow-up rates. The probability systematic sampling method was used to select patients from the selected clinics. Data were collected through semi-structured interviews, and content analysis was used to analyse the data. Results: Patients’ and nurses’ perspectives on barriers contributing to the loss of follow-up among people living with HIV included lack of confidentiality, lack of understanding of antiretroviral treatment, patients’ self-transfer, and feeling better physically. Conclusion: Understanding the reasons for the Loss of follow-up could inform the development of retention in care interventions for Limpopo province. The study can be most beneficial with HIV education, skills building, and outreach programme strategies; this will, in turn, increase the knowledge needed to better attract and retain HIV-positive patients in healthcare settings.

Salud y Orgullo Mexicano: Development of a Culturally Specific Transnational Linkage and Retention in Care Intervention for Mexican Men Who Have Sex with Men Living with HIV in Chicago.

This manuscript documents the development of an innovative individual-level peer navigation intervention "Salud y Orgullo Mexicano" (SOM) designed to increase linkage and retention to HIV care for Mexican men who have sex with men (MSM) in Chicago, Illinois. The intervention was developed via a modified intervention mapping process. Elements of two existing interventions were combined and refined with input from the Mexican MSM community, including informant interviews, an expert advisory board, and a design team. A manualized transnational intervention was developed via intervention mapping. A peer health navigation intervention "SOM" was created using intervention mapping and input from the focus community. Next steps include implementing and evaluating the intervention to determine acceptability and efficacy.

The differential impacts of non-locally acquired infections and treatment interventions on heterosexual HIV transmission in Hong Kong.

IntroductionHeterosexual infections have contributed to a high proportion of the HIV burden in Asia and Eastern Europe. Human mobility and non-local infections are important features in some cities/countries. An understanding of the determinants of the sustained growth of the heterosexual HIV epidemics would enable the potential impacts of treatment-based interventions to be assessed.MethodsWe developed a compartmental model for heterosexual HIV transmissions, parameterized by clinical and surveillance data (1984–2014) in Hong Kong. HIV sequence data were included for examining genetic linkages and clustering pattern. We performed sensitivity analyses to evaluate effects of high-risk sexual partnership and proportions of non-locally acquired infections. Four hypothetical interventions (a) immediate treatment, (b) enhancement of retention in care, (c) HIV testing campaigns, and (d) test-and-treat strategy, were examined.ResultsData of 2174 patients (723 female and 1451 male) diagnosed with HIV between 1984 and 2012 in Hong Kong were collected for model parameterization. Among 1229 sequences of non-MSM (men who have sex with men) patients, 70% were isolates and 17% were either dyads or triads. In base-case scenario, the total estimated number of new infections in 2012–2023 would be 672 for male and 452 for female. Following 100% retention in care intervention, the total proportion of averted new infections in 2012–2023 would be 7% for male and 10% for female. HIV testing campaign in 2012 and 2017 followed by 100% immediate treatment strategy would avert 5% and 9% of male and female new infections, respectively. In the epidemic model, an increase of high-risk sexual partnership from 6% to 9% would increase the epidemic growth (annual number of newly diagnosed and newly infected cases) by about 10%. If no non-locally acquired infection occurred as from 2012, the epidemic growth would slump. To control the heterosexual epidemic, periodic HIV testing at 5-year intervals with immediate treatment would avert 5–13% of annual new infections in 2013–2023.ConclusionsEnhanced HIV testing with immediate treatment is most effective in controlling the heterosexual epidemic, the impacts of which might however be attenuated by any increase of non-locally acquired infection, assuming little variations of high risk partnership over time.

Correlates of Durable Viral Suppression (DVS) Among Criminal Justice-involved (CJI) Black Men Living with HIV in Louisiana.

Durable viral suppression (DVS) is needed to reduce HIV transmission risk and prevent new HIV infections. We examined changes in viral suppression and correlates of DVS among 97 criminal justice-involved (CJI) Black men living with HIV in Louisiana enrolled in a linkage, re-engagement, and retention in care intervention. Most participants (75%) were Black men who have sex with men. Forty-four percent (44%) were virally suppressed at baseline and only 20% had achieved DVS over a 12-month period. Multinomial logistic regression analyses showed that compared with DVS participants, those with no viral suppression (NVS) and some viral suppression (SVS) were more likely to have lived with HIV for a longer period of time and were less likely to be adherent at baseline. Medication adherence was critical for DVS among this sample of CJI Black men living with HIV who represent a high priority population for HIV care and treatment interventions.

Voluntary Community Human Immunodeficiency Virus Testing, Linkage, and Retention in Care Interventions in Kenya: Modeling the Clinical Impact and Cost-effectiveness.

BackgroundIn southwest Kenya, the prevalence of human immunodeficiency virus (HIV) infection is about 25%. Médecins Sans Frontières has implemented a voluntary community testing (VCT) program, with linkage to care and retention interventions, to achieve the Joint United Nations Program on HIV and AIDS (UNAIDS) 90-90-90 targets by 2017. We assessed the effectiveness and cost-effectiveness of these interventions.MethodsWe developed a time-discrete, dynamic microsimulation model to project HIV incidence over time in the adult population in Kenya. We modeled 4 strategies: VCT, VCT-plus-linkage to care, a retention intervention, and all 3 interventions combined. Effectiveness outcomes included HIV incidence, years of life saved (YLS), cost (2014 €), and cost-effectiveness. We performed sensitivity analyses on key model parameters.ResultsWith current care, the projected HIV incidence for 2032 was 1.51/100 person-years (PY); the retention and combined interventions decreased incidence to 1.03/100 PY and 0.75/100 PY, respectively. For 100000 individuals, the retention intervention had an incremental cost-effectiveness ratio (ICER) of €130/YLS compared with current care; the combined intervention incremental cost-effectiveness ratio was €370/YLS compared with the retention intervention. VCT and VCT-plus-linkage interventions cost more and saved fewer life-years than the retention and combined interventions. Baseline HIV prevalence had the greatest impact on the results.ConclusionsInterventions targeting VCT, linkage to care, and retention would decrease HIV incidence rate over 15 years in rural Kenya if planned targets are achieved. These interventions together would be more effective and cost-effective than targeting a single stage of the HIV care cascade.

Is more research always needed? Estimating optimal sample sizes for trials of retention in care interventions for HIV-positive East Africans

IntroductionGiven the serious health consequences of discontinuing antiretroviral therapy, randomised control trials of interventions to improve retention in care may be warranted. As funding for global HIV research is finite,...

The Cost and Threshold Analysis of Retention in Care (RiC): A Multi-Site National HIV Care Program.

Persons diagnosed with HIV but not retained in HIV medical care accounted for the majority of HIV transmissions in 2009 in the United States (US). There is an urgent need to implement and disseminate HIV retention in care programs; however little is known about the costs associated with implementing retention in care programs. We assessed the costs and cost-saving thresholds for seven Retention in Care (RiC) programs implemented in the US using standard methods recommended by the US Panel on Cost-effectiveness in Health and Medicine. Data were gathered from accounting and program implementation records, entered into a standardized RiC economic analysis spreadsheet, and standardized to a 12month time frame. Total program costs for from the societal perspective ranged from $47,919 to $423,913 per year or $146 to $2,752 per participant. Cost-saving thresholds ranged from 0.13 HIV transmissions averted to 1.18 HIV transmission averted per year. We estimated that these cost-saving thresholds could be achieved through 1 to 16 additional person-years of viral suppression. Across a range of program models, retention in care interventions had highly achievable cost-saving thresholds, suggesting that retention in care programs are a judicious use of resources.

Barriers and Facilitators to Interventions Improving Retention in HIV Care: A Qualitative Evidence Meta-Synthesis.

Retention in HIV care is vital to the HIV care continuum. The current review aimed to synthesize qualitative research to identify facilitators and barriers to HIV retention in care interventions. A qualitative evidence meta-synthesis utilizing thematic analysis. Prospective review registration was made in PROSPERO and review procedures adhered to PRISMA guidelines. Nineteen databases were searched to identify qualitative research conducted with individuals living with HIV and their caregivers. Quality assessment was conducted using CASP and the certainty of the evidence was evaluated using CERQual. A total of 4419 citations were evaluated and 11 were included in the final meta-synthesis. Two studies were from high-income countries, 3 from middle-income countries, and 6 from low-income countries. A total of eight themes were identified as facilitators or barriers for retention in HIV care intervention: (1) Stigma and discrimination, (2) Fear of HIV status disclosure, (3) task shifting to lay health workers, (4) Human resource and institutional challenges, (5) Mobile Health (mHealth), (6) Family and friend support, (7) Intensive case management, and, (8) Relationships with caregivers. The current review suggests that task shifting interventions with lay health workers were feasible and acceptable. mHealth interventions and stigma reduction interventions appear to be promising interventions aimed at improving retention in HIV care. Future studies should focus on improving the evidence base for these interventions. Additional research is needed among women and adolescents who were under-represented in retention interventions.

Mobile technology use and desired technology-based intervention characteristics among HIV+ Black men who have sex with men

ABSTRACTHIV positive Black men who have sex with men (MSM) are retained in HIV medical care at suboptimal rates. Interventions targeted to Black MSM are needed to help to improve their retention in care. The purposes of this study were to investigate the use of mobile technology among HIV+ Black MSM and to explore participants’ thoughts about the use of mobile technology for HIV retention in care interventions. Twenty-two HIV+ Black MSM completed a technology use survey and participated in a qualitative interview regarding technology-based interventions. The majority of participants (95%) had access to a cell phone, and used their phones frequently (median 3 hours/day). Men preferred interventions that would allow for anonymous participation and that would provide individually tailored support. Mobile technology is a promising approach to intervention delivery for both younger and older HIV+ Black MSM. These interventions should incorporate features that are desirable to men (i.e., anonymous participation and individual tailoring).

The Contribution of Missed Clinic Visits to Disparities in HIV Viral Load Outcomes.

We explored the contribution of missed primary HIV care visits ("no-show") to observed disparities in virological failure (VF) among Black persons and persons with injection drug use (IDU) history. We used patient-level data from 6 academic clinics, before the Centers for Disease Control and Prevention and Health Resources and Services Administration Retention in Care intervention. We employed staged multivariable logistic regression and multivariable models stratified by no-show visit frequency to evaluate the association of sociodemographic factors with VF. We used multiple imputations to assign missing viral load values. Among 10 053 patients (mean age = 46 years; 35% female; 64% Black; 15% with IDU history), 31% experienced VF. Although Black patients and patients with IDU history were significantly more likely to experience VF in initial analyses, race and IDU parameter estimates were attenuated after sequential addition of no-show frequency. In stratified models, race and IDU were not statistically significantly associated with VF at any no-show level. Because missed clinic visits contributed to observed differences in viral load outcomes among Black and IDU patients, achieving an improved understanding of differential visit attendance is imperative to reducing disparities in HIV.

Clinic-wide intervention lowers financial risk and improves revenue to HIV clinics through fewer missed primary care visits.

: We calculated the financial impact in 6 HIV clinics of a low-effort retention in care intervention involving brief motivational messages from providers, patient brochures, and posters. We used a linear regression model to calculate absolute changes in kept primary care visits from the preintervention year (2008-2009) to the intervention year (2009-2010). Revenue from patients' insurance was also assessed by clinic. Kept visits improved significantly in the intervention year versus the preintervention year (P < 0.0001). We found a net-positive effect on clinic revenue of +$24,000/year for an average-size clinic (7400 scheduled visits/year). We encourage HIV clinic administrators to consider implementing this low-effort intervention.

Estimating the cost of increasing retention in care for HIV-infected patients: results of the CDC/HRSA retention in care trial.

Retaining HIV patients in medical care promotes access to antiretroviral therapy, viral load suppression, and reduced HIV transmission to partners. We estimate the programmatic costs of a US multisite randomized controlled trial of an intervention to retain HIV patients in care. Six academically affiliated HIV clinics randomized patients to intervention (enhanced personal contact with patients across time coupled with basic HIV education) and control [standard of care (SOC)] arms. Retention in care was defined as 4-month visit constancy, that is, at least 1 primary care visit in each 4-month interval over a 12-month period. We used microcosting methods to collect unit costs and measure the quantity of resources used to implement the intervention in each clinic. All fixed and variable labor and nonlabor costs of the intervention were included. Visit constancy was achieved by 45.7% (280/613) of patients in the SOC arm and by 55.8% (343/615) of patients in the intervention arm, representing an increase of 63 patients (relative improvement 22.1%; 95% confidence interval: 9% to 36%; P < 0.01). The total annual cost of the intervention at the 6 clinics was $241,565, the average cost per patient was $393, and the estimated cost per additional patient retained in care beyond SOC was $3834. Our analyses showed that a retention in care intervention consisting of enhanced personal contact coupled with basic HIV education may be delivered at fairly low cost. These results provide useful information for guiding decisions about planning or scaling-up retention in care interventions for HIV-infected patients.

Measuring Retention in HIV Care

Measuring retention in HIV primary care is complex, as care includes multiple visits scheduled at varying intervals over time. We evaluated 6 commonly used retention measures in predicting viral load (VL) suppression and the correlation among measures. Clinic-wide patient-level data from 6 academic HIV clinics were used for 12 months preceding implementation of the Centers for Disease Control and Prevention/Health Resources and Services Administration (CDC/HRSA) retention in care intervention. Six retention measures were calculated for each patient based on scheduled primary HIV provider visits: count and dichotomous missed visits, visit adherence, 6-month gap, 4-month visit constancy, and the HRSA HIV/AIDS Bureau (HRSA HAB) retention measure. Spearman correlation coefficients and separate unadjusted logistic regression models compared retention measures with one another and with 12-month VL suppression, respectively. The discriminatory capacity of each measure was assessed with the c-statistic. Among 10,053 patients, 8235 (82%) had 12-month VL measures, with 6304 (77%) achieving suppression (VL <400 copies/mL). All 6 retention measures were significantly associated (P < 0.0001) with VL suppression (odds ratio; 95% CI, c-statistic): missed visit count (0.73; 0.71 to 0.75, 0.67), missed visit dichotomous (3.2; 2.8 to 3.6, 0.62), visit adherence (3.9; 3.5 to 4.3,0.69), gap (3.0; 2.6 to 3.3, 0.61), visit constancy (2.8; 2.5 to 3.0, 0.63), and HRSA HAB (3.8; 3.3 to 4.4, 0.59). Measures incorporating "no-show" visits were highly correlated (Spearman coefficient = 0.83-0.85), as were measures based solely on kept visits (Spearman coefficient = 0.72-0.77). Correlation coefficients were lower across these 2 groups of measures (range = 0.16-0.57). Six retention measures displayed a wide range of correlation with one another, yet each measure had significant association and modest discrimination for VL suppression. These data suggest there is no clear gold standard and that selection of a retention measure may be tailored to context.

Interventions to improve retention in HIV primary care: a systematic review of U.S. studies.

Retaining HIV-diagnosed persons in care is a national priority, but little is known on what intervention strategies are most effective for promoting retention in care. We conducted a systematic search and qualitatively reviewed 13 published studies and three recent conference presentations to identify evidence-informed retention strategies. We extracted information on study design, methods, and intervention characteristics. Strengths-based case management that encourages clients to recognize and use their own internal abilities to access resources and solve problems offered strong evidence for retention in care. Other evidence-informed strategies included peer navigation, reducing structural- and system-level barriers, including peers as part of a health care team, displaying posters and brochures in waiting rooms, having medical providers present brief messages to patients, and having clinics stay in closer contact with patients across time. Opportunities for additional intervention strategies include using community-based organizations as a setting for engaging HIV-infected persons about the importance of regular care and involving patients' significant others in retention in care interventions.
