Linkages to care for newly diagnosed individuals who test HIV positive in nonprimary care settings

Innovation and implementation determinants of HIV testing and linkage-to-care in the U.S.: a systematic review

OBJECTIVE

To identify innovation and implementation determinants of HIV testing, diagnosis, and linkage-to-care in the U.S.

DATA SOURCES AND STUDY SETTING

Between November 2020 and January 2022, a broad search strategy was employed in three literature databases: Ovid MEDLINE, PsycINFO, and Web of Science.

STUDY DESIGN

A systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement.

DATA COLLECTION/EXTRACTION METHODS

A team of master's and Ph.D.-level researchers screened eligible studies against the inclusion criteria and extracted the data using COVIDENCE software in pairs with consensus performed by a senior member of the team. Barriers and facilitators were extracted and analyzed according to the Consolidated Framework for Implementation Research (CFIR). Frequency of determinants across studies was mapped according to CFIR, valence, study design, delivery setting, unit of analysis, population of interest, region of the U.S., and year.

RESULTS

We identified 1,739 implementation and innovation determinants from 186 articles. Most determinants were for HIV testing rather than linkage-to-care. Most determinants were identified in the inner setting and individuals domains of CFIR, with the fewest identified in the process and innovations domains. Determinants of providers were only slightly more frequently identified than determinants of recipients. However, determinants of organizations and systems were rarely identified.

CONCLUSION

This review provides a synthesis of innovation and implementation determinants of HIV testing and linkage-to-care using the most-cited implementation science (IS) framework, CFIR. This synthesis enables the larger field of HIV science to utilize IS in efforts to end the HIV epidemic and positions IS to consider the application of IS frameworks to fields like HIV.

Long-Acting Reversible Contraception Knowledge Among Female Adolescents Presenting to a Pediatric Emergency Department

OBJECTIVES

The objective of this study was to assess awareness and use of long-acting reversible contraception (LARC) among female adolescents presenting to a pediatric emergency department (PED).

STUDY DESIGN

During routine presentation to an urban PED in New Jersey, female adolescents, aged 15-19 years, were asked to voluntarily complete an electronic survey about sexual practices and contraception. The PED is in an urban teaching hospital, treating 35,000 children annually. Patients could schedule a follow-up appointment at the hospital's obstetrics/gynecology clinic. Data were collected over 13 months, and follow-up was monitored to determine if they attended an outpatient appointment, and if so, what the outcome was.

RESULTS

Data for 199 participants were analyzed. The median age of participants was 18 years, whereas 79% self-identified as Black, and 17.6% self-identified as Latina. Twenty-one percent of participants used a form of birth control during their first sexual encounter, the largest percentage being condoms (77.8%). Forty percent of participants reported some prior knowledge about contraceptive implants, and 20% had knowledge about intrauterine devices, whereas only 3 (1.5%) intrauterine devices and 2 (1%) arm implants had been previously used. Of the 78 participants that requested a follow-up, 14 (17.9%) completed their appointment. Of those, 2 (14%) were prescribed contraception (Depo-Provera shot and oral contraceptive pills).

CONCLUSIONS

Knowledge about LARC remains low in our PED, despite it being the most effective method of contraception. Even when interventions were made to link interested respondents to outpatient women's health services, follow-up attendance was poor, and no patients obtained LARC. There is a significant discrepancy between the consensus standard of contraception care across all relevant medical specialties and current utilization by high-risk populations. Future efforts must focus on how to close this gap, and the ED could be pivotal for improving both reproductive health education and intervention among adolescent patients.

Preexposure Prophylaxis for Women Across the Criminal Justice System: Implications for Policy and Practice

Data that inform preexposure prophylaxis (PrEP) implementation for women involved in criminal justice (WICJ) systems are scarce. In a survey of PrEP attitudes, acceptability, and barriers across the criminal justice system, incarcerated women (n = 48) were more likely than WICJ on probation (n = 125) to be eligible for PrEP (29% vs. 15%; p = .04) and willing to take PrEP if offered (94% vs. 78%; p = .01). In multivariate models, PrEP eligibility directly correlated with being incarcerated (adjusted odds ratio [aOR] 4.81, 95% confidence interval [CI] 1.76-13.1) and inversely correlated with Hispanic/Latina ethnicity (aOR 0.31; 95% CI 0.10-0.96). Recent partner violence exposure was associated with PrEP eligibility (aOR 3.29; 95% CI 1.54-7.02) and discordant risk perception (aOR 2.36; 95% CI 1.18-4.70). Findings demonstrate high potential for PrEP for all WICJ, though implementation efforts will need to address partner violence.

Interprofessional collaboration associated with frequency of life-saving links to HIV continuum of care services in the urban environment of Newark, New Jersey

BACKGROUND

HIV continuum of care has been used as a strategy to reduce HIV transmission rates, with timely engagement in HIV testing being the first and most critical step. This study examines interprofessional-collaboration (IPC) after controlling for agency/ provider demographics, provider training and self-efficacy as a significant predictor of how frequently HIV service providers link their clients to HIV testing.

METHODS

Multilevel binary logistic regression analysis was conducted to examine the effects of IPC on links to HIV testing while controlling for demographic and agency information, provider training, and standardized measures of providers' feelings, attitudes, and opinions about IPC. Cross-sectional data from 142 providers in 13 agencies offering treatment and prevention services for HIV and substance-use disorders were collected via a survey.

RESULTS

Those who scored higher on the IPC scale reported significantly higher rates of linkages to HIV testing. Compared to the null model (i.e., no predictor model), the final multilevel binary logistic regression model showed a significantly improved likelihood of linkage to HIV testing by 11.4%, p. < .05. The final model correctly classified 90.2% of links to HIV testing. Providers in agencies with smaller budgets and in agencies offering substance use disorder services were more likely to link clients to HIV testing. Younger providers who received HIV training were also more likely to link clients to HIV testing.

CONCLUSIONS

Findings suggest IPC training as a potential strategy to improve linkages to HIV testing for clients at risk for HIV infection. Future research is recommended to identify specific areas of IPC that might have differential effects on links to HIV testing.

A systematic review of the geospatial barriers to antiretroviral initiation, adherence and viral suppression among people living with HIV

Background With the emergence of antiretroviral therapy (ART), Treatment as Prevention (TasP) has become the cornerstone of both HIV clinical care and HIV prevention. However, despite the efficacy of treatment-based programs and policies, structural barriers to ART initiation, adherence and viral suppression have the potential to reduce TasP effectiveness. These barriers have been studied using Geographic Information Systems (GIS). While previous reviews have examined the use of GIS for HIV testing - an essential antecedent to clinical care - to date, no reviews have summarised the research with respect to other ART-related outcomes.

METHODS

Therefore, the present review leveraged the PubMed database to identify studies that leveraged GIS to examine the barriers to ART initiation, adherence and viral suppression, with the overall goal of understanding how GIS has been used (and might continue to be used) to better study TasP outcomes. Joanna Briggs Institute criteria were used for the critical appraisal of included studies.

RESULTS

In total, 33 relevant studies were identified, excluding those not utilising explicit GIS methodology or not examining TasP-related outcomes.

CONCLUSIONS

Findings highlight geospatial variation in ART success and inequitable distribution of HIV care in racially segregated, economically disadvantaged, and, by some accounts, increasingly rural areas - particularly in the United States. Furthermore, this review highlights the utility and current limitations of using GIS to monitor health outcomes related to ART and the need for careful planning of resources with respect to the geospatial movement and location of people living with HIV (PLWH).

Effect of a Rapid Test Algorithm on Linkage to Medical Care and Viral Suppression Among New Jersey Residents, 2007 to 2015

BACKGROUND

Efforts to identify and link human immunodeficiency virus-infected persons to medical care are the first steps to achieving viral suppression. In the United States, the goals are to link 85% of newly diagnosed persons to medical care in 30 days or less and for 80% to become virally suppressed by 2020. Among newly diagnosed residents from 2007 to 2015, in New Jersey, we evaluated the impact of a rapid testing algorithm (RTA) on linkage to medical care and viral suppression.

METHODS

This is a retrospective review of data from New Jersey's Enhanced HIV/AIDS Reporting System for residents, newly diagnosed at 13 years or older, from 2007 to 2015. We used survival analysis methods to estimate the proportion of residents and time to linkage to medical care and viral suppression.

RESULTS

Of 8508 newly diagnosed residents, 60.3% and 72.3% were linked to medical care in 30 days or less and 90 days or less, respectively; 45.7% achieved viral suppression in 365 days or less. Linkage to medical care in 90 days or less and viral suppression in 365 days or less were more likely among those tested by RTA than laboratory testing. The adjusted hazard ratios for linkage to medical care, in clinical sites were 1.41, (95% confidence interval [CI], 1.22-1.63 and 1.08, 95% CI, 0.97-1.2 in community sites. The adjusted hazard ratios for viral suppression in clinical sites were 1.25 (95% CI, 1.05-1.47 and 1.16, 95% CI, 1.01-1.32, in community sites.

CONCLUSIONS

Implementation of a RTA may eliminate barriers to linkage to medical care and viral suppression leading to decreased morbidity, mortality, and transmission.

Developing a Patient Navigation Program to Improve Engagement in HIV Medical Care and Viral Suppression: A Demonstration Project Protocol

Individuals diagnosed and living with HIV who are out of care or who have persistent viremia are at risk for poor health outcomes and are estimated to account for two-thirds of all new HIV infections. As part of a six-state demonstration project to improve access to care for hard-to-reach populations, Wisconsin developed an HIV-specific patient navigation program to improve engagement in HIV care and viral suppression for populations at risk for poor HIV care outcomes. Patient navigators worked with individuals who were out of HIV medical care or were at risk of falling out of care over nine months to identify and address barriers to care. This manuscript describes the patient navigation program and rationale, and lessons learned that should be considered by sites developing similar programs.

Interprofessional Collaboration and On-the-Job Training Improve Access to HIV Testing, HIV Primary Care, and Pre-Exposure Prophylaxis (PrEP)

The HIV Continuum of Care is a global priority, yet vulnerable patients face access/retention challenges. Research is missing on the role social and public health service providers can play to help these patients. Using structural equation modeling, we examined the effects of interprofessional collaboration (IPC) and on-the-job training on the frequency of linkages to HIV testing, HIV primary care, and on pre-exposure prophylaxis (PrEP) psychoeducation. The sample included 285 New York City providers of social and public health services from 34 agencies. Forty-eight percent of providers had not offered PrEP psychoeducation and linked fewer than five patients to HIV testing and primary care per week. However, in multivariate analysis higher IPC was associated with more linkages and frequent psychoeducation. After adjusting for IPC, linkage training was associated with more frequent services. The influence of specific factors highlights areas for interventions and policies to improve access to the HIV Continuum of Care.

Linkage between HIV diagnosis and care: Understanding the role of gender in a Northern Province in Vietnam

Early linkage to HIV care is associated significantly with improved patient outcomes and reduced the risk of HIV transmission. However, delays between HIV diagnosis and registering for care have prevailed in Vietnam. The aim of researchers in this study is to examine linkages to care for individuals newly diagnosed with HIV in 2014, especially to highlight the impact of gender upon these linkages in a Northern Province of Ninh Binh. We collected secondary data of all 125 eligible HIV positive people diagnosed in 2014 and conducted a gender-based descriptive analysis of their registration to care within 6 months. Nineteen in-depth interviews and two focus group discussions were completed. We found that women accounted for one-third of newly diagnosed cases (42/125), but initiated HIV treatment at an earlier stage of HIV disease than men (65% women at stage 1, 2 versus 31% in men). Stigma and discrimination was greater among women while inadequate awareness of treatment was greater for men. Dissatisfaction with HIV testing and counseling and no or passive referral to treatment were other barriers for both the genders for enrolling in care services after diagnosis.

Integrating a Statewide HIV Call Line: An Innovative and Tailored Approach for Rapid Linkage to HIV Care

Only 80% of people living with HIV (PLWH) in the United States are linked to care, 40% are engaged in care, and 30% have achieved viral load suppression. We addressed linkage to care with a pilot program of a statewide referral call center to connect PLWH and their non-HIV specialty providers to HIV care. Callers received tailored referrals from nurses trained to work in an existing call center, using an electronic assessment tool and a comprehensive HIV provider list. Of 122 calls, 85% were from PLWH and 15% from providers calling about a patient. Overall, 88 of 104 (84.6%) PLWH and 16 of 18 (88.9%) providers accepted care referral, including 13% of PLWH callers without prior HIV care. Results indicated that the call center was an acceptable strategy for HIV care referral; the use of an existing call center facilitated feasibility of the program and improved linkage to HIV care.

Improving linkage to HIV care at low-threshold STI/HIV testing sites: An evaluation of the Immediate Staging Pilot Project in Vancouver, British Columbia

OBJECTIVES

The objective of the Immediate Staging Pilot Project (ISPP) was to improve linkage to human immunodeficiency virus (HIV) care by increasing the number of referrals made to HIV care, and to decrease the time between diagnosis and linkage to care for newly diagnosed HIV clients. This pilot had the potential to decrease HIV transmission at a population level by engaging clients in treatment earlier.

SETTING

The Bute Street Clinic and Health Initiative for Men Clinic on Davie in Vancouver, British Columbia are low-threshold public health facilities providing HIV/STI testing primarily to men who have sex with men (MSM).

INTERVENTION

To improve engagement of MSM in the cascade of HIV care, the BC Centre for Disease Control implemented a 12-month ISPP in 2012 for clients newly diagnosed with HIV. The pilot offered CD4 and viral load testing at the time of diagnosis, implemented improved referral procedures and enhanced nursing support for clients.

OUTCOMES

Comparing linkage to care outcomes between a group that received the standard of care (SOC) and an intervention group that received immediate staging, the median linkage to care time decreased from 21.5 to 14.0 days respectively (p = 0.053). The referral rates to HIV care were 56.1% in the SOC group and 94.1% in the intervention group (p &lt; 0.001).

CONCLUSION

Creating best practices that include offering CD4 and viral load testing at the time of diagnosis, enhanced nursing support and standardized referral processes has facilitated an improvement in the quality of HIV services provided to MSM clients attending low-threshold clinics.

Linkage and Referral to HIV and Other Medical and Social Services: A Focused Literature Review for Sexually Transmitted Disease Prevention and Control Programs

BACKGROUND

Sexually transmitted disease (STD) program and clinic staff play an important role in providing linkage and referrals to programs and services that address the complex medical and psychosocial needs of their clients. We synthesized recent published literature related to effective practices for linkage to care for HIV and referral to other medical and social services.

METHODS

Three PubMed searches were conducted to identify relevant studies published since 2004 on (1) linkage to HIV care, (2) referral within STD clinical contexts, and (3) (review articles only) referral practices among all medical specialties. Systematic review procedures were not used.

RESULTS

Thirty-three studies were included in this review. Studies highlight the limited value of passive referral practices and the increased effectiveness of active referral and linkage practices. Numerous studies on linkage to HIV care suggest that case management approaches, cultural-linguistic concordance between linkage staff and clients, and structural features such as colocation facilitate timely linkage to care. Integration of other medical and social services such as family planning and alcohol screening services into STD settings may be optimal but resource-intensive. Active referral practices such as having a written referral protocols and agreements, using information technology to help transfer information between providers, and making appointments for clients may offer some benefit. Few studies included information on program costs associated with linkage and referral.

CONCLUSIONS

Recent literature provides some guideposts for STD program and clinical staff to use in determining their approach to helping link and refer clients to needed care. Much experience with these issues within STD services remains unpublished, and key gaps in the literature remain.

Linkage-to-care Methods and Rates in U.S. Emergency Department-based HIV Testing Programs: A Systematic Literature Review Brief Report

BACKGROUND

An increasing number of U.S. emergency departments (EDs) have implemented ED-based HIV testing programs since the Centers for Disease Control and Prevention issued revised HIV testing recommendations for clinical settings in 2006. In 2010, the National HIV/AIDS Strategy (NHAS) set an linkage-to-care (LTC) rate goal of 85% within 90 days of HIV diagnosis. LTC rates for newly diagnosed HIV-infected patients vary markedly by site, and many are suboptimal. The optimal approach for LTC in the ED setting remains unknown.

OBJECTIVE

The objective was to perform a brief descriptive analysis of the LTC methods practiced in EDs across the United States to determine the overall linkage rate of ED-based HIV testing programs.

METHODS

We conducted a systematic review of literature related to U.S. ED HIV testing in the adult population using PubMed, Embase, Web of Science, Scopus, and Cochrane. There were 333 articles were identified; 31 articles were selected after a multiphasic screening process. We analyzed data from the 31 articles to assess LTC methods and rates. LTC methods that involved physical escort of the newly diagnosed patient to an HIV/infectious disease (ID) clinic or interaction with a specialist health care provider at the ED were operationally defined as "intensive" LTC protocol. "Mixed" LTC protocol was defined as a program that employed intensive linkage only part of the coverage hours. All other forms of linkage was defined as "nonintensive" LTC protocol. An LTC rate of ≥85% was used to identify characteristics of ED-based HIV testing program associated with a higher LTC rate.

RESULTS

There were 37 ED-based HIV testing programs in the 31 articles. The overall LTC rate was 74.4%. Regarding type of protocol, nine (24.3%) employed intensive LTC protocols, 25 (67.6%) nonintensive, two (5.4%) mixed, and one (2.7%) with unclear protocols. LTC rates for programs with intensive and nonintensive LTC protocols were 80.0 and 72.7%, respectively. Four (44.4%) with intensive protocols and nine (36.0%) with the nonintensive protocols had LTC rates > 85%. The linkage staff employed was different between ED programs. Among them, 25 (67.6%) programs used exogenous staff, 10 (27.0%) used the ED staff, and two had no information. All the programs in the nonintensive group utilized drop-in HIV/ID clinic or medical appointments while seven of nine of the programs in the intensive group physically escorted the patients to the initial medical intake appointment. There were no significant differences in characteristics of ED-based HIV testing programs between those with ≥85% LTC rate versus those with <85% within the intensive or nonintensive group.

CONCLUSION

Intensive LTC protocols had a higher LTC rate and a higher proportion of programs that surpassed the >85% NHAS goal compared to nonintensive methods, suggesting that, when possible, ED-based HIV testing programs should adopt intensive LTC strategies to improve LTC outcomes. However, intensive LTC protocols most often required involvement of multidisciplinary non-ED professionals and external research funding. Our findings provide a foundation for developing best practices for ED-based HIV LTC programs.

Expanded HIV Testing and Linkage to Care: Conventional vs. Point-of-Care Testing and Assignment of Patient Notification and Linkage to Care to an HIV Care Program

OBJECTIVE

The University of Chicago Medicine (UCM) led the Expanded Testing and Linkage to Care (X-TLC) program for disproportionately affected populations on the South Side of Chicago. The X-TLC program aimed to expand routine HIV testing to high-prevalence communities with disproportionately affected populations (i.e., minority men and women, men who have sex with men, and intravenous drug users) according to CDC guidelines at multiple clinical sites.

METHODS

The X-TLC program used standard blood-based laboratory testing vs. point-of-care rapid testing or rapid laboratory testing with point-of-care results notification. Site coordinators and the linkage-to-care coordinator at UCM oversaw testing, test notification, and linkage to care.

RESULTS

From February 1, 2011, through December 31, 2013, the X-TLC program completed 75,345 HIV tests on 67,153 unique patients. Of the total tests, 48,044 (63.8%) were performed on patients who self-identified as African American and 6,606 (8.8%) were performed on patients who self-identified as Hispanic. Of the 67,153 patients tested, 395 (0.6%) tested positive and 176 (0.3%) were previously unaware of their HIV-positive status. Seroprevalence was even higher for EDs, where 127 of 12,957 patients tested positive for HIV (1.0% seroprevalence), than for other patient care sites, including for new diagnoses, where 50 of 12,957 patients tested positive for HIV (0.4% seroprevalence). Of the 176 newly diagnosed patients, 166 of 173 (96.0%) patients who were still alive when testing was complete received their test results, and 148 of the 166 patients who were eligible for care (89.0%) were linked to care. Patients linked to X-TLC physicians did well with respect to the continuum of care: 77 of 123 (62.6%) patients achieved HIV viral load of <200 copies/milliliter.

CONCLUSION

Lead organizations such as UCM were able to assist and oversee HIV screening and linkage to care for HIV patients diagnosed at community sites. HIV screening and linkage to care can be accomplished by incorporating standard testing for HIV into routine medical care.

Black:White Disparities in HIV Mortality in the United States: 1990-2009

OBJECTIVES

The aim of this study was to assess whether racial disparities in human immunodeficiency virus (HIV) mortality in the USA have changed over time.

METHODS

Using vital records from the National Center for Health Statistics and census data from the US Census Bureau, we calculated the race- and gender-specific HIV mortality rates and corresponding racial rate ratios for non-Hispanic Blacks and non-Hispanic Whites in the USA for four 5-year increments from 1990-2009. Rates were age-adjusted using the 2000 USA standard population. Additionally, we calculated excess Black deaths for 2005-2009.

RESULTS

For the total, male, and female populations, we observed a statistically significant increase in the Black:White HIV mortality disparity between T1 (1990-1994) and T4 (2005-2009). The increasing disparity was due to the fact that the decrease in mortality rates from T1 to T4 was greater among Whites than Blacks. This disparity led to 5603 excess Black deaths in the USA at T4.

CONCLUSIONS

Previous research suggests that as HIV becomes more treatable, racial disparities widen, as observed in this study for both men and women. Existing disparities could be ameliorated if access to care were equal among these groups. Equal access would enable more individuals to achieve viral suppression, the final step of the HIV Care Continuum.

Shifting the paradigm: using HIV surveillance data as a foundation for improving HIV care and preventing HIV infection

CONTEXT

Reducing HIV incidence in the United States and improving health outcomes for people living with HIV hinge on improving access to highly effective treatment and overcoming barriers to continuous treatment. Using laboratory tests routinely reported for HIV surveillance to monitor individuals' receipt of HIV care and contacting them to facilitate optimal care could help achieve these objectives. Historically, surveillance-based public health intervention with individuals for HIV control has been controversial because of concerns that risks to privacy and autonomy could outweigh benefits. But with the availability of lifesaving, transmission-interrupting treatment for HIV infection, some health departments have begun surveillance-based outreach to facilitate HIV medical care.

METHODS

Guided by ethics frameworks, we explored the ethical arguments for changing the uses of HIV surveillance data. To identify ethical, procedural, and strategic considerations, we reviewed the activities of health departments that are using HIV surveillance data to contact persons identified as needing assistance with initiating or returning to care.

FINDINGS

Although privacy concerns surrounding the uses of HIV surveillance data still exist, there are ethical concerns associated with not using HIV surveillance to maximize the benefits from HIV medical care and treatment. Early efforts to use surveillance data to facilitate optimal HIV medical care illustrate how the ethical burdens may vary depending on the local context and the specifics of implementation. Health departments laid the foundation for these activities by engaging stakeholders to gain their trust in sharing sensitive information; establishing or strengthening legal, policy and governance infrastructure; and developing communication and follow-up protocols that protect privacy.

CONCLUSIONS

We describe a shift toward using HIV surveillance to facilitate optimal HIV care. Health departments should review the considerations outlined before implementing new uses of HIV surveillance data, and they should commit to an ongoing review of activities with the objective of balancing beneficence, respect for persons, and justice.
