Outreach program contacts: do they increase the likelihood of engagement and retention in HIV primary care for hard-to-reach patients?

Evaluation of a Public Health Referral System to Re-Engage Individuals Living With HIV Who Have Interrupted Antiretroviral Therapy in British Columbia, Canada

BACKGROUND

In 2016, the British Columbia HIV/AIDS Drug Treatment Program modified its prescriber alert system for antiretroviral therapy (ART) interruptions to include referrals to regional public health nursing teams for direct outreach support for those who remain off treatment for 4 months or longer. We evaluated clinically relevant outcomes of this Re-Engagement and Engagement in Treatment for Antiretroviral Interrupted and Naïve populations (RETAIN) initiative, in comparison to previous time-periods.

METHODS

We analyzed ART interruptions triggering alerts in pre-RETAIN (July 2013-April 2016) and post-RETAIN periods (May 2016-October 2017) with follow-up continuing until October 2018. We compared the proportions of those who restarted ART and achieved viral suppression in pre-RETAIN and post-RETAIN periods and the time to ART restart using generalized estimating equations. Cox proportional hazards modelling was used to examine associations with time-to-ART-restart.

RESULTS

A total of 1805 individuals experienced ART interruptions triggering 3219 alerts; 2050 in pre-RETAIN and 1169 in post-RETAIN periods. Participants were predominantly men (74%) and had a median duration of ART of 5 years. Among persons who remained interrupted >4 months after an ART interruption alert was sent, the median time from interruption to ART re-initiation declined from 8.7 months to 7.4 months (P < 0.001) from pre-to post-RETAIN periods. Interruptions in the post-RETAIN era were associated with an increased hazard of restarting ART (adjusted hazard ratio 1.51; 95% CI: 1.34 to 1.69).

CONCLUSIONS

Public health referrals shortened the length of ART interruptions after alerts sent to prescribers had not resulted in re-engagement. Similar programs should be considered in other jurisdictions.

Toward An Enhanced Understanding of HIV Patient Navigation as a Health Care Intervention: An Analysis of Navigation in Practice

Patient navigation is a promising strategy for improving health among persons with multiple barriers to HIV care, yet little is known about navigation's core components. From 24 systematically identified navigation studies, we abstracted navigators' activities, grouped activities into 20 thematic activity categories, and ordered them by frequency. Subsequently, Principal Components Analysis of activity categories was used identify independent clusters. Accompaniment characterized 71% of navigation programs; ≥ half included health education (58%), collaboration/coordination (58%), linkage-to-care (54%), transportation support (54%), service referrals (50%) and instrumental support (50%). Five unique components (comprising 13 activity categories) were identified: (1) services beyond office, (2) health education and relationship building, (3) accompaniment and instrumental support, (4) locating patients and tracking information, and (5) beyond HIV care. Navigators who located patients or tracked information were less likely to provide accompaniment or instrumental support (r = - 0.60, p = 0.002). Findings can enhance precision in developing, describing, evaluating and improving navigation programs.

The effect of a Housing First intervention on primary care retention among homeless individuals with mental illness

Background

Primary care retention, defined as ongoing periodic contact with a consistent primary care provider, is beneficial for people with serious chronic illnesses. This study examined the effect of a Housing First intervention on primary care retention among homeless individuals with mental illness.

Methods

Two hundred individuals enrolled in the Toronto site of the At Home Project and randomized to Housing First or Treatment As Usual were studied. Medical records were reviewed to determine if participants were retained in primary care, defined as having at least one visit with the same primary care provider in each of two consecutive six-month periods during the 12 month period preceding and following randomization.

Results

Medical records were obtained for 47 individuals randomized to Housing First and 40 individuals randomized to Treatment As Usual. During the one year period following randomization, the proportion of Housing First and Treatment As Usual participants retained in primary care was not significantly different (38.3% vs. 47.5%, p = 0.39). The change in primary care retention rates from the year preceding randomization to the year following randomization was +10.6% in the Housing First group and -5.0% in the Treatment As Usual group.

Conclusion

Among homeless individuals with mental illness, Housing First did not significantly affect primary care retention over the follow-up period. These findings suggest Housing First interventions may need to place greater emphasis on connecting clients with primary care providers.

Predictive Analytics for Retention in Care in an Urban HIV Clinic

Consistent medical care among people living with HIV is essential for both individual and public health. HIV-positive individuals who are ‘retained in care’ are more likely to be prescribed antiretroviral medication and achieve HIV viral suppression, effectively eliminating the risk of transmitting HIV to others. However, in the United States, less than half of HIV-positive individuals are retained in care. Interventions to improve retention in care are resource intensive, and there is currently no systematic way to identify patients at risk for falling out of care who would benefit from these interventions. We developed a machine learning model to identify patients at risk for dropping out of care in an urban HIV care clinic using electronic medical records and geospatial data. The machine learning model has a mean positive predictive value of 34.6% [SD: 0.15] for flagging the top 10% highest risk patients as needing interventions, performing better than the previous state-of-the-art logistic regression model (PPV of 17% [SD: 0.06]) and the baseline rate of 11.1% [SD: 0.02]. Machine learning methods can improve the prediction ability in HIV care clinics to proactively identify patients at risk for not returning to medical care.

The Impact of Clinic Policy Attendance and the Ryan White HIV/AIDS Medical Case Management Program on HIV Clinical Outcomes: A Retrospective Longitudinal Study

Clinic appointment attendance is a significant determinant of improved HIV health outcomes. A retrospective longitudinal analysis from 2009 to 2015 examined the relationship of clinic policy attendance with and without medical case management (MCM) on HIV clinical outcomes. Clinical parameters were abstracted across the study years and latent growth models measured HIV clinical outcomes as a function of time. A total of 2773 patients were included in this study. More than the majority of individuals had 75% clinic policy attendance during each of the study years and the median number of MCM contact visits with the case manager was 4.0 visits per year (p < 0.01). While the overall trend identified improved HIV clinical outcomes across the clinic population over the study period, it also revealed individuals receiving MCM and with 75% clinic policy attendance had significantly faster improvement in HIV clinical outcomes compared to the individuals who did not receive MCM nor had 75% clinic policy attendance. This study identified how MCM, in combination with clinic policy attendance efforts, are useful in quickly improving HIV viral load and CD4 T-cell count. These findings support the continued need for funding of the Ryan White Care Act as it assists with the support of MCM and appointment attendance through the guidance of wrap-around services.

The Effect of Empowerment and Educational Programs on the Quality of Life in Iranian Women with HIV

AIDS affects physical, mental, social, and psychological health status. One of the goals of Health for All in the 21st century is to improve the quality of life. This study is a randomized clinical trial conducted on 120 HIV-positive women. Women were administered assessment questionnaires to be completed during the structured interview. After sample collection, participants were divided randomly into 3 groups by using the table of random numbers, then, respectively, received educational intervention, empowerment program, and routine procedures offered by the center and were followed by refilling the questionnaires 12 weeks after intervention. Depending on the type of data, chi-square, analysis of variance, and paired t test were used, and SPSS version 16 was used for data analysis. The finding showed that knowledge increased after intervention in educational ( P = .02) and empowerment groups ( P = .006); also empowerment group indicated significant difference in psychological ( P = .006) and spiritual ( P = .001) domains and their total quality of life ( P = .004). According to this study, exposing HIV-positive women to empowerment education is effective in improving their quality of life.

Reducing HIV-Related Health Disparities in the Health Resources and Services Administration's Ryan White HIV/AIDS Program

The Health Resources and Services Administration's Ryan White HIV/AIDS Program (RWHAP) supports direct health care treatment and support services to more than 50% of all people living with diagnosed HIV in the United States. A critical goal of the RWHAP is to reduce HIV-related health disparities to help end the HIV epidemic. From 2010 through 2016, the RWHAP made significant progress reducing viral suppression disparities among client populations, particularly among women, transgender persons, youths, Blacks or African Americans, and unstably housed clients. To assist with the reduction of the remaining disparities in HIV-related health outcomes among clients, the RWHAP continues to support planning and resource allocation for RWHAP Parts A through D and AIDS Drug Assistance Program, as well as through implementing policy and program initiatives, Special Projects of National Significance, evaluation studies, and collaborations to disseminate effective interventions.

Development of PositiveLinks: A Mobile Phone App to Promote Linkage and Retention in Care for People With HIV

Background

Linkage to and retention in HIV care are challenging, especially in the Southeastern United States. The rise in mobile phone app use and the potential for an app to deliver just in time messaging provides a new opportunity to improve linkage and retention among people living with HIV (PLWH).

Objective

This study aimed to develop an app to engage, link, and retain people in care. We evaluated the acceptability, feasibility, and impact of the app among users.

Methods

App development was informed by principles of chronic disease self-management and formative interviews with PLWH. Once developed, the app was distributed among participants, and usability feedback was incorporated in subsequent iterations. We interviewed app users after 3 weeks to identify usability issues, need for training on the phone or app, and to assess acceptability. We tracked and analyzed usage of app features for the cohort over 2 years.

Results

A total of 77 participants used the app during the pilot study. The query response rate for the first 2 years was 47.7%. Query response declined at a rate of 0.67% per month. The community message board was the most popular feature, and 77.9% (60/77) of users posted on the board at least once during the 2 years.

Conclusions

The PositiveLinks app was feasible and acceptable among nonurban PLWH. High participation on the community message board suggests that social support from peers is important for people recently diagnosed with or returning to care for HIV.

Is HIV patient navigation associated with HIV care continuum outcomes?

OBJECTIVE

To provide the first systematic review on the associations between HIV patient navigation and HIV care continuum outcomes (i.e. linkage to care, retention in care, antiretroviral therapy (ART) uptake, medication adherence, and viral suppression) in the United States. We identified primary research studies that addressed these associations and qualitatively assessed whether provision of patient navigation was positively associated with these outcomes, including strength of the evidence.

METHODS

A systematic review, including both electronic [MEDLINE (OVID), EMBASE (OVID), PsycINFO (OVID), and CINAHL (EBSCOhost)] online databases and manual searches, was conducted to locate studies published from 1 January 1996 through 23 April 2018.

RESULTS

Twenty studies met our inclusion criteria. Of these, 17 found positive associations. Patient navigation was more likely to be positively associated with linkage to care (five of six studies that assessed this association), retention in care (10 of 11), and viral suppression (11 of 15) than with ART uptake (one of four) or ART adherence (two of four). However, almost two-thirds of the 17 studies were of weak study quality, and only three used a randomized controlled trial design.

CONCLUSION

Available evidence suggests that patient navigation is a potentially effective strategy to enhance engagement in care among persons with HIV. However encouraging, the evidence is still weak. Studies with more rigorous methodological designs, and research examining characteristics of navigators or navigational programs associated with better outcomes, are warranted given the current interest and use of this strategy.

Re-engagement in HIV care following a missed visit in rural Uganda

OBJECTIVE

We conducted a retrospective cohort study to assess the effect of tracking People Living with HIV (PLHIV) after missed clinic visits and factors associated with return to care in rural Uganda. We assessed retention in care among 650 HIV-infected women and men. We used univariable and multivariable generalized linear models to assess demographic and self-reported factors associated with re-engagement in HIV care.

RESULTS

Of 381 PLHIV who ever missed a scheduled appointment, 68% were female and most (80%) had initiated ART. Most (70%) of those tracked returned to care. Relative to men, women (adjusted risk ratio [ARR] 1.23; 95% confidence interval (CI) 1.05-1.43; p = 0.009) were more likely to return to care after active tracking. PLHIV who missed scheduled visits for other reasons (forgetting, adequate drug supplies, or long distance to clinic) had reduced odds of return to care (ARR 0.41; 95% CI 0.28-0.59; p < 0.001). These data support close monitoring of patient retention in HIV care and active measures to re-engage those who miss an appointment. Furthermore, they highlight the need for targeted interventions to those more resistant to re-engagement such as men.

Randomized Trial of a Health Coaching Intervention to Enhance Retention in Care: California Collaborative Treatment Group 594

Poor linkage, engagement and retention remain significant barriers in achieving HIV treatment goals in the US. HIV-infected persons entering or re-entering care across three Southern California academic HIV clinics, were randomized (1:1) to an Active, Linkage, Engagement, Retention and Treatment (ALERT) specialist for outreach and health coaching, or standard of care (SOC). The primary outcome of time to loss to follow up (LTFU) was compared using Cox proportional hazards regression modeling. No differences in the median time to LTFU (81.7 for ALERT versus 93.6 weeks for SOC; HR 1.27; p = 0.40), or time to ART initiation was observed (N = 116). Although, ALERT participants demonstrated worsening depressive symptomatology from baseline to week 48 compared to SOC (p = 0.02). The ALERT intervention did not improve engagement and retention in HIV care over SOC. Further studies are needed to determine how best to apply resources to improve retention and engagement.

Peer Support and the HIV Continuum of Care: Results from a Multi-Site Randomized Clinical Trial in Three Urban Clinics in the United States

Racial/ethnic minorities living with HIV and behavioral health co-morbidities are more likely to be disengaged from HIV primary care. Peer programs have been effective in HIV outreach and prevention but effectiveness of such programs for retention in care and viral suppression is understudied. Subjects (n = 348) were randomized in equal allocation to a peer navigation and education intervention versus standard clinical care at three urban clinics in the United States. The intervention group received seven structured interventions plus weekly contact to address medical and social needs. Primary outcomes included time-to-first 4-month gap in HIV care and viral suppression up to 12 months of follow-up. Intention-to-treat analysis showed no difference between groups on 4-month gap in HIV primary care, but subgroup analysis showed a suggestive effect of the peer intervention in reducing gaps in care among stably housed subjects. Fully compliant subjects in the peer intervention experienced significantly fewer 4-month gaps in HIV primary care (p < 0.0001). Those in the peer group who had more clinical face-to-face encounters in the first 3 months were also significantly more likely to have better retention in care (p = 0.04). There were no significant differences between any study subgroups in viral suppression at 12 months. Peer interventions may improve retention in primary care among subgroups of people living with HIV from racial/ethnic minority communities, although such improved retention may not increase viral load suppression. Attending and completing structured educational sessions along with early, intensive contact with peers could improve retention in HIV primary care for patients. Future peer programs should consider training on housing referral systems to help increase retention for patients who are not stably housed. clinicaltrials.gov registration number: NCT01616940.

A Critical Review and Commentary on the Challenges in Engaging HIV-Infected Latinos in the Continuum of HIV Care

Antiretroviral therapy for treatment of HIV infection has become increasingly effective. Persistent poor HIV outcomes in racial and ethnic minority populations in the US call for a closer examination into why Latinos are at significant risk for acquiring and dying from HIV. To improve clinical outcomes and achieve an AIDS-free generation, HIV research must address disparities in HIV outcomes in Latinos, the largest ethnic/racial minority population in the US. Immigrant status as well as cultural factors influence HIV care utilization and are essential to highlight for effective intervention development in Latinos. A better understanding of these individual and contextual factors is critical to developing tailored approaches to engaging Latinos in HIV care. Based on a comprehensive literature review, we offer a framework for understanding what is needed from clinical practice and research to improve engagement in HIV care for US-based Latinos. These findings may have implications for other minority populations.

Barriers and Facilitators to the Implementation of a National HIV Linkage, Re-Engagement, and Retention in Care Program

The 2020 National HIV AIDS Strategy (NHAS) sets a target of 90% of diagnosed people living with HIV (PLWH) retained in HIV care. Access to Care (A2C) was a national HIV linkage, re-engagement, and retention in care program funded by AIDS United with support from the Corporation for National and Community Service that aimed to link and retain the most vulnerable PLWH into high-quality HIV care. This study explores the barriers and facilitators of implementing the A2C program from the perspective of program staff. Ninety-eight qualitative interviews were conducted with staff at implementing organizations over the 5 years of the project. Barriers included challenges with recruiting and retaining participants, staffing and administration, harmonizing partnerships, and addressing the basic and psychosocial needs of participants. Facilitators included strong relationships with partner organizations, flexible program models, and the passion and dedication of staff. Findings will inform the development of future programs and policy.

Challenges in the Evaluation of Interventions to Improve Engagement Along the HIV Care Continuum in the United States: A Systematic Review

In the United States (US), there are high levels of disengagement along the HIV care continuum. We sought to characterize the heterogeneity in research studies and interventions to improve care engagement among people living with diagnosed HIV infection. We performed a systematic literature search for interventions to improve HIV linkage to care, retention in care, reengagement in care and adherence to antiretroviral therapy (ART) in the US published from 2007-mid 2015. Study designs and outcomes were allowed to vary in included studies. We grouped interventions into categories, target populations, and whether results were significantly improved. We identified 152 studies, 7 (5%) linkage studies, 33 (22%) retention studies, 4 (3%) reengagement studies, and 117 (77%) adherence studies. 'Linkage' studies utilized 11 different outcome definitions, while 'retention' studies utilized 39, with very little consistency in effect measurements. The majority (59%) of studies reported significantly improved outcomes, but this proportion and corresponding effect sizes varied substantially across study categories. This review highlights a paucity of assessments of linkage and reengagement interventions; limited generalizability of results; and substantial heterogeneity in intervention types, outcome definitions, and effect measures. In order to make strides against the HIV epidemic in the US, care continuum research must be improved and benchmarked against an integrated, comprehensive framework.

Enhancing patient navigation to improve intervention session attendance and viral load suppression of persons with HIV and substance use: a secondary post hoc analysis of the Project HOPE study

Background

Interventions are needed to improve viral suppression rates among persons with HIV and substance use. A 3-arm randomized multi-site study (Metsch et al. in JAMA 316:156–70, 2016) was conducted to evaluate the effect on HIV outcomes of usual care referral to HIV and substance use services (N = 253) versus patient navigation delivered alone (PN: N = 266) or together with contingency management (PN + CM; N = 271) that provided financial incentives targeting potential behavioral mediators of viral load suppression.

Aims

This secondary analysis evaluates the effects of financial incentives on attendance at PN sessions and the relationship between session attendance and viral load suppression at end of the intervention.

Methods

Frequency of sessions attended was analyzed over time and by distribution of individual session attendance frequency (PN vs PN + CM). Percent virally suppressed (≤200 copies/mL) at 6 months was compared for low, medium and high rate attenders. In PN + CM a total of $220 could be earned for attendance at 11 PN sessions over the 6-month intervention with payments ranging from $10 to $30 under an escalating schedule.

Results

The majority (74%) of PN-only participants attended 6 or more sessions but only 28% attended 10 or more and 16% attended all eleven sessions. In contrast, 90% of PN + CM attended 6 or more visits, 69% attended 10 or more and 57% attended all eleven sessions (attendance distribution χ²[11] = 105.81; p < .0001). Overall (PN and PN + CM participants combined) percent with viral load suppression at 6-months was 15, 38 and 54% among those who attended 0–5, 6–9 and 10–11 visits, respectively (χ²(2) = 39.07, p < .001).

Conclusion

In this secondary post hoc analysis, contact with patient navigators was increased by attendance incentives. Higher rates of attendance at patient navigation sessions was associated with viral suppression at the 6-month follow-up assessment. Study results support use of attendance incentives to improve rates of contact between service providers and patients, particularly patients who are difficult to engage in care.

Retention, Antiretroviral Therapy Use and Viral Suppression by History of Injection Drug Use Among HIV-Infected Patients in an Urban HIV Clinical Cohort

Compared to HIV-infected persons who do not inject drugs (non-IDU), persons who inject drugs (PWID) experience disparities in linking to medical care, initiating antiretroviral therapy (ART) and achieving viral suppression. There has been little attention to changes in these disparities over time. We estimated the proportion of PWID and non-IDU retained in care, on ART, and virally suppressed each year from 2001-2012 in the Johns Hopkins HIV Clinical Cohort (JHHCC). We defined active clinic patients as those who had ≥1 clinical visit, CD4 cell count, or viral load between July 1 of the prior year, and June 30 of the analysis year. Within a calendar year, retention was defined as ≥2 clinical visits or HIV-related laboratory measurements >90 days; ART use was defined as ≥1 ART prescription active ≥30 days; and viral suppression was defined as ≥1 HIV viral load <400 copies/mL. While PWID were less likely to be retained in earlier years, the gaps in retention closed around 2010. After 2003-2004, PWID and non-IDU retained in care had similar probability of receiving a prescription for ART and PWID and non-IDU on ART had similar probability of viral suppression.

What Will It Take to End the HIV/AIDS Epidemic? Linking the Most Disenfranchised Into Care Through Outreach

The 2015 National HIV/AIDS Strategy renewed its goal of increasing access to care for people living with HIV/AIDS (PLWHA) and called for an increased focus on linkage to care efforts. As many PLWHA face multiple barriers to care and live on the margins of society, adoption of intensive outreach activities is necessary to engage the most disenfranchised PLWHA into care and to ultimately end the HIV epidemic. The Bay Area Network for Positive Health (BANPH), comprising 12+ agencies, established a network outreach model for our linkage-to-care project to engage the hardest-to-reach populations in the San Francisco Bay Area. During the years 2010-2013, BANPH agencies conducted street outreach, analyzed internal tracking systems to identify out-of-care individuals and individuals experiencing tenuous care, and surveyed participants using Apple iPod Touch devices. During the 3-year project, BANPH agencies engaged 602 out-of-care PLWHA and linked 440 to care. On average, outreach workers made 10 contact attempts with a client to link them to care. Sixty-three percent of participants were linked to care on an average of 56 days after initial contact. Factors, including lack of case management, lack of transportation, competing concerns, substance abuse, and HIV stigma, were significantly associated with linkage-to-care outcomes. Intensive outreach efforts could help to reduce barriers to care for hard-to-reach PLWHA, but these efforts require a tremendous amount of time and resources. A network outreach model could help facilitate sharing of limited resources and increase regional outreach capacity for linkage-to-care programs.

Feasibility of identifying out of care HIV-positive patients in a hospital setting and enrolling them in a retention intervention

BACKGROUND

The hospital setting provides an opportunity to re-engage people living with HIV (PLWH) in HIV care. We developed and implemented a protocol to identify PLWH in a hospital setting. The aim of the current study was to report on our strategy to recruit hospitalized HIV patients into an intervention study, and to report on lessons learned for future studies.

METHODS

Our protocol was developed based on experience of our research staff in recruiting HIV patients as well as clinical input from providers and administrators on delivering care in hospitalized settings. We identified hospitalized PLWH between 2010 and 2013 who were potentially eligible for an intervention study. Patients were identified by review of electronic medical records and clinician referral, followed by in-person screening to confirm eligibility. We examined factors related to identifying and enrolling hospitalized patients, and documented lessons learned.

RESULTS

Key strategies included systematic medical record review followed by in-person screening, collaboration with staff, and flexibility in recruitment logistics. We identified 1801 PLWH hospitalized during the 3-year study period. Eighty-four percent (n = 1514) met the met the inclusion criteria based on medical record review. Of these, 48% (n = 733) were ineligible. Among eligible patients, 59% (n = 460) were enrolled. Only 3% (n = 23) of eligible patients declined; 84% (n = 321) were not enrolled because they were discharged before enrollment. Lessons learned included (1) needing to identify patients and deliver the intervention before hospital discharge, (2) limiting the complexity of the intervention, and (3) having research staff available on weekends and after hours.

CONCLUSIONS

Targeted recruitment of hospitalized populations is a feasible and productive approach for finding and engaging PLWH who are newly diagnosed or out of routine care.

Organization of care for persons with HIV-infection: a systematic review

The objective of this systematic review was to examine the effectiveness of the organization of care: case management, multidisciplinary care, multi-faceted treatment, hours of service, outreach programs and health information systems on medical, immunological, virological, psychosocial and economic outcomes for persons living with HIV/AIDS. We searched PubMed (MEDLINE) and 10 other electronic databases from 1 January 1980 to April, 2012 for both experimental and controlled observational studies. Thirty-three studies met the inclusion criteria. Eleven studies were randomized controlled trials (RCTs), three of which were conducted in low-middle income settings. Patient characteristics, study design, organization measures and outcomes data were abstracted independently by two reviewers from all studies. A risk of bias tool was applied to RCTs and a separate tool was used to assess the quality of observational studies. This review concludes that case management interventions were most consistently associated with improvements in immunological outcomes but case management demonstrates no clear association with other outcome measures. The same mixed results were also identified for multidisciplinary and multi-faceted care interventions. Eight studies with an outreach intervention were identified and demonstrated improvements or non-inferiority with respect to mortality, receipt of antiretroviral medications, immunological outcomes, improvements in healthcare utilization and lower reported healthcare costs when compared to usual care. Of the interventions examined in this review, sustained in-person case management and outreach interventions were most consistently associated with improved medical and economic outcomes, in particular antiretroviral prescribing, immunological outcomes and healthcare utilization. No firm conclusions can be reached about the impact of any one intervention on patient mortality.

Outcomes of a Clinic-Based Surveillance-Informed Intervention to Relink Patients to HIV Care

BACKGROUND

Improving patient retention in HIV care is crucial to improving the HIV care continuum. We instituted and evaluated a relinkage program that uses clinical data to identify potentially out-of-care patients, matches those data to public health surveillance, and employs a linkage specialist (LS) to coordinate care relinkage.

METHODS

The intervention began November 1, 2012, in the largest HIV clinic in Washington State. We evaluated program outcomes and compared patient outcomes in the year after initiation of the intervention to a historical control cohort of patients. Cox proportional hazard ratios were used to compare time to relinkage to care between cohorts, and regression models using generalized estimated equations were preformed to examine secondary outcomes of relinkage to care, engagement in care, and viral suppression.

RESULTS

A total of 753 patients were identified as "out of care" on November 1, 2012. Matching with surveillance data and initial LS investigations found that 596 (79%) of these patients had moved, transferred care, or were incarcerated. Of the 157 remaining patients, 40 (25%) relinked to care before LS contact, and the LS successfully contacted 38 (24%). A total of 116 (15%) patients in the intervention cohort relinked to care and 24 (20%) were contacted by the LS. Compared with the historical cohort, the time to relinkage was shorter among patients in the intervention cohort [adjusted hazard ratio = 1.7 (1.2-2.3)] and a greater proportion relinked (15% vs. 10%).

CONCLUSIONS

This clinic-based surveillance-informed relinkage intervention showed statistically significant but modest effectiveness in returning out-of-care patients to HIV care compared with historical controls.

Using a Multitest Algorithm to Improve the Positive Predictive Value of Rapid HIV Testing and Linkage to HIV Care in Nonclinical HIV Test Sites

BACKGROUND

Use of a rapid HIV testing algorithm (RTA) in which all tests are conducted within one client appointment could eliminate off-site confirmatory testing and reduce the number of persons not receiving confirmed results.

METHODS

An RTA was implemented in 9 sites in Los Angeles and San Francisco; results of testing at these sites were compared with 23 sites conducting rapid HIV testing with off-site confirmation. RTA clients with reactive results on more than 1 rapid test were considered HIV+ and immediately referred for HIV care. The positive predictive values (PPVs) of a single rapid HIV test and the RTA were calculated compared with laboratory-based confirmatory testing. A Poisson risk regression model was used to assess the effect of RTA on the proportion of HIV+ persons linked to HIV care within 90 days of a reactive rapid test.

RESULTS

The PPV of the RTA was 100% compared with 86.4% for a single rapid test. The time between testing and receipt of RTA results was on average 8 days shorter than laboratory-based confirmatory testing. For risk groups other than men who had sex with men, the RTA increased the probability of being in care within 90 days compared with standard testing practice.

CONCLUSIONS

The RTA increased the PPV of rapid testing to 100%, giving providers, clients, and HIV counselors timely information about a client's HIV-positive serostatus. Use of RTA could reduce loss to follow-up between testing positive and confirmation and increase the proportion of HIV-infected persons receiving HIV care.

Visits to primary care physicians among persons who inject drugs at high risk of hepatitis C virus infection: room for improvement

The role of primary care physicians (PCP) in hepatitis C virus (HCV) prevention is increasingly emphasized. Yet, little is known about the patterns of contacts with PCP among persons who inject drugs (PWID). We sought to assess the 6-month prevalence of PCP visiting among PWID at risk of HCV infection and to explore the associated factors. Baseline data were collected from HCV-seronegative PWID recruited in HEPCO, an observational Hepatitis Cohort study (2004-2011) in Montreal, Canada. An interviewer-administered questionnaire elicited information on socio-demographic factors, drug use patterns and healthcare services utilization. Blood samples were tested for HCV antibodies. Using the Gelberg-Andersen Behavioral Model, hierarchical logistic regression analyses were conducted to identify predisposing, need and enabling factors associated with PCP visiting. Of the 349 participants (mean age = 34; 80.8% male), 32.1% reported visiting a PCP. In the multivariate model, among predisposing factors, male gender [adjusted odds ratio (AOR) = 0.45 (0.25-0.83)], chronic homelessness [AOR = 0.08 (0.01-0.67)], cocaine injection [AOR = 0.46 (0.28-0.76)] and reporting greater illegal or semi-legal income [AOR = 0.48 (0.27-0.85)] were negatively associated with PCP visits. Markers of need were not associated with the outcome. Among enabling factors, contact with street nurses [AOR = 3.86 (1.49-9.90)] and food banks [AOR = 2.01 (1.20-3.37)] was positively associated with PCP visiting. Only one third of participating PWID reported a recent visit to a PCP. While a host of predisposing factors seems to hamper timely contacts with PCP among high-risk PWID, community-based support services may play an important role in initiating dialogue with primary healthcare services in this population.

High Treatment Retention Rate in HIV-Infected Patients Receiving Antiretroviral Therapy at Two Large HIV Clinics in Hanoi, Vietnam

Background

Loss to follow-up (LTFU) is viewed as a major challenge in improving retention in HIV treatment. In Vietnam, the reasons for disengagement from clinics and the effect of injection drug use (IDU) on LTFU with unknown outcome (true LTFU) are not well known.

Methods

Patients receiving antiretroviral therapy (ART) from two HIV clinics in Hanoi were included in this observational study between 2007 and 2012, and followed up every 6 months until the end of 2013. The reasons for disengagement from the clinic, and ART status during imprisonment were investigated in patients with a history of IDU to identify true LTFU. The retention rate at 6–54 months and true LTFU rate were calculated. Cox proportional hazards regression models were performed to identify factors associated with true LTFU.

Results

There were 1,431 patients, with a follow-up time of 4,371 person-years (median 2.49 years). At the end of the follow-up period, 71 (5.0%) patients died, 79 (5.5%) transferred to other clinics, 16 (1.1%) disengaged from the clinics, and the calculated true LTFU was 45 (3.1%), with 12-month ART retention rate of 95.3% for the entire study population. Imprisonment was the most frequent reason for disengagement from the clinics. True LTFU correlated significantly with low CD4 count and high plasma viral load, but not history of IDU.

Conclusion

Imprisonment is a major cause of disengagement from HIV care among patients with a history of IDU.

Enhancing linkage and retention in HIV care: a review of interventions for highly resourced and resource-poor settings

Given the widespread availability of effective antiretroviral therapy, engagement of HIV-infected persons in care is a global priority. We reviewed 51 studies, published in the past decade, assessing strategies for improving linkage to and retention in HIV care. The review included studies from highly resourced settings (HRS) and resource-poor settings (RPS), specifically the USA and sub-Saharan Africa. In HRS, strength-based case management was best supported for improving linkage and retention in care; peer navigation and clinic-based health promotion were supported for improving retention. In RPS, point of care CD4 testing was best supported for improving linkage to care; decentralization, and task-shifting for improving retention. Novel interventions continue to emerge in HRS and RPS, yet many strategies have not been adequately evaluated. Further consideration should be given to analyses that identify which interventions, or combinations of interventions, are most effective, cost-effective, scalable, and aligned with patient preferences for HIV care.

Benefits of a routine opt-out HIV testing and linkage to care program for previously diagnosed patients in publicly funded emergency departments in Houston, TX

BACKGROUND

The Routine Universal Screening for HIV program provides opt-out HIV testing and linkage to care for emergency department (ED) patients in Harris Health System, Houston, TX. Seventy-five percent of patients testing positive in this program have been previously diagnosed. Whether linkage to care is increased among these patients is unknown.

METHODS

We conducted a retrospective cohort study of persons tested for HIV in the ED between 2008 and 2012 but had a previously documented positive HIV test ≥1 year prior. Outcomes were engagement in care (≥1 HIV outpatient visits in 6 months), retention in care (≥2 HIV outpatient visits in 12 months, at least 3 months apart), and virologic suppression (<200 copies/mL in 12 months) compared before and after the ED visit. Analysis was conducted using McNemar test and multivariate conditional logistic regression.

RESULTS

A total of 202,767 HIV tests identified 2068 previously diagnosed patients. The mean age was 43 years with 65% male and 87% racial and ethnic minorities. Engagement in care increased from 41.3% previsit to 58.8% postvisit (P < 0.001). Retention in care increased from 32.6% previsit to 47.1% postvisit (P < 0.001). Virologic suppression increased from 22.8% previsit to 34.0% postvisit (P < 0.001). Analyses revealed that engagement in care after visit improved most among younger participants (ages 16-24 years), retention improved across all groups, and virologic suppression improved most among participants aged 25-34 years.

CONCLUSIONS

Routine opt-out HIV testing in an ED paired with standardized service linkage improves engagement, retention, and virologic suppression in previously diagnosed patients.

Missing data in substance abuse research? Researchers' reporting practices of sexual orientation and gender identity

BACKGROUND

Lesbian, gay, bisexual, and transgender individuals are at higher risk for substance use and substance use disorders than heterosexual individuals and are more likely to seek substance use treatment, yet sexual orientation and gender identity are frequently not reported in the research literature. The purpose of this study was to identify if sexual orientation and gender identity are being reported in the recent substance use literature, and if this has changed over time.

METHOD

The PsycINFO and PubMed databases were searched for articles released in 2007 and 2012 using the term "substance abuse" and 200 articles were randomly selected from each time period and database. Articles were coded for the presence or absence of sexual orientation and gender identity information.

RESULTS

Participants' sexual orientation was reported in 3.0% and 4.9% of the 2007 and 2.3% and 6.5% of the 2012 sample, in PsycINFO and PubMed sample articles, respectively, while non-binary gender identity was reported in 0% and 1.0% of the 2007 sample and 2.3% and 1.9% of the 2012 PsycINFO and PubMed sample articles. There were no differences in rates of reporting over time.

CONCLUSIONS

Sexual orientation and gender identity are rarely reported in the substance abuse literature, and there has not been a change in reporting practices between 2007 and 2012. Recommendations for future investigators in reporting sexual orientation and gender identity are included.

Interventions that retain African Americans in HIV/AIDS treatment: implications for social work practice and research

Social workers play an important role in recognizing and addressing barriers to retention in HIV care. Although there is a large body of literature and research supporting interventions that promote medication adherence, there is limited intervention research that addresses retention in care, the precursor to adherence. Despite many advances in HIV treatment, many African Americans are not engaged in regular care. In a systematic review, the literature was critically appraised to examine intervention research designed to retain HIV-infected African Americans in treatment. Only peer-reviewed studies published from January 2002 through October 2012 were examined. The initial search generated a total of 798 studies. However, of these, only 13 met the inclusion criteria. Results highlight interventions that can be replicated by social workers--such as the use of ancillary support services, the use of adherence manuals, and theory-based interventions--to engage this population in care. Policy implications are also discussed.

Risk factors for delayed entrance into care after diagnosis among patients with late-stage HIV disease in southern Vietnam

BACKGROUND

We surveyed HIV patients with late-stage disease in southern Vietnam to determine if barriers to access and service quality resulted in late HIV testing and delays from initial diagnosis to entry into HIV care.

METHODOLOGY

196 adult patients at public HIV clinics with CD4 counts less than 250 cells/mm3 completed a standardized questionnaire. We used multivariate analysis to determine risk factors for delayed entry into care, defined as >3 months time from diagnosis to registration.

RESULTS

Common reasons for delayed testing were feeling healthy (71%), fear of stigma and discrimination in the community (43%), time conflicts with work or school (31%), did not want to know if infected (30%), and fear of lack of confidentiality (27%). Forty-five percent of participants delayed entry into care with a median CD4 count of 65 cells/mm3. The most common reasons for delayed entry were feeling healthy (51%), fear of stigma and discrimination in the community (41%), time conflicts with work or school (33%), and fear of lack of confidentiality (26%). Independent predictors for delayed entry were feeling healthy (aOR 3.7, 95% CI 1.5-9.1), first positive HIV test at other site (aOR 2.9, CI 1.2-7.1), history of injection drug use (IDU) (aOR 2.9, 95% CI 1.1-7.9), work/school conflicts (aOR 4.3, 95% CI 1.7-10.8), prior registration at another clinic (aOR 77.4, 95% CI 8.6-697), detention or imprisonment (aOR 10.3, 95% CI 1.8-58.2), and perceived distance to clinic (aOR 3.7, 95% CI 1.0-13.7).

CONCLUSION

Delayed entry into HIV care in Vietnam is common and poses a significant challenge to preventing AIDS and opportunistic infections, decreasing mortality, and reducing HIV transmission. Improved linkages between testing and care are needed, particularly for patients who feel healthy, as well as incarcerated and drug-using populations who may face structural and social barriers to accessing care.

Factors associated with returning to HIV care after a gap in care in New York State

BACKGROUND

Retention in HIV care has important implications. Few studies examining retention include comprehensive and heterogeneous populations, and few examine factors associated with returning to care after gaps in care. We identified reasons for gaps in care and factors associated with returning to care.

METHODS

We extracted medical record and state-wide reporting data from 1865 patients with 1 HIV visit to a New York facility in 2008 and subsequent 6-month gap in care. Using mixed effect logistic regression, we examined sociodemographic, clinical, and facility characteristics associated with returning to care.

RESULTS

Most patients were men (63.2%), black (51.4%), had Medicaid (53.9%). Many had CD4 counts >500 cells per cubic millimeter (34.4%) and undetectable viral loads (45.0%). Most (55.9%) had unknown reasons for gaps in care; of those with known reasons, reasons varied considerably. After a gap, 54.6% returned to care. Patients who did (vs. did not) return to care were more likely to have stable housing, longer duration of HIV, high CD4 count, suppressed viral load, antiretroviral medications, and had facilities attempt to contact them. Those who returned to care were less likely to be uninsured and have mental health problems or substance use histories.

CONCLUSION

Over half of our sample of patients in New York with 1 HIV visit and subsequent 6-month gap in care returned to care; no major reasons for gaps emerged. Nevertheless, our findings emphasize that stabilizing patients' psychosocial factors and contacting patients after a gap in care are key strategies to retain HIV-positive patients in care in New York.

The role of jails in engaging PLWHA in care: from jail to community

HIV testing in jails has provided public health officials with the opportunity to not only identify new cases of HIV but to also reestablish contact with previously diagnosed individuals, many of whom never entered care following diagnosis or entered care but then dropped out. The presence of inmates throughout the HIV/AIDS continuum of care suggests that jails can play a strategic role in engaging persons living with HIV and AIDS in care. In order to be successful in structuring HIV/AIDS programs in jails, health care and correctional officials will be well-served to: (1) understand the HIV/AIDS continuum of care from the standpoint of engagement interventions that promote participation; (2) be aware of jail, community, and prison interventions that promote engagement in care; (3) anticipate and plan for the unique barriers jails provide in implementing engagement interventions; and, (4) be creative in designing engagement interventions suitable for both newly and previously diagnosed individuals.

HIV care in the Swedish-Danish HIV cohort 1995-2010, closing the gaps

Background

Successful treatment reduces morbidity, mortality and transmission of HIV. We evaluated trends in the treatment status of HIV infected individuals enrolled in care in Sweden and Denmark during the years 1995-2010. Our aim was to assess the proportion of HIV-infected individuals who received services along the continuum of care in Denmark in 2010, and to discuss the findings in relation to the organization of the health care system.

Methods

We analyzed CD4 counts and viral loads (VL) among all HIV patients enrolled in the cohort. For each month of the study period we estimated the proportions of patients who 1) had initiated highly active antiretroviral treatment (HAART) and had VL<500 copies/mL, 2) were not eligible for HAART, 3) had initiated HAART but had VL≥500 copies/mL, 4) were eligible for, but had not initiated HAART and 5) had initiated HAART but no VL monitoring for >13 months or 6) no HAART or monitoring of CD4 for >13 months. Patients fulfilling criteria 1 or 2 were considered successfully managed.

Results

The proportion of successfully managed patients continued to increase throughout the study period and reached 83% in 2010, 92% of Swedish/Danish men who have sex with men and heterosexual patients, but only 74% of immigrants and 78% of injection drug users were successfully managed due to higher rates of inadequate monitoring in the latter two groups. In 2010, 70% of all individuals diagnosed with HIV in Denmark were virally suppressed.

Conclusion

In a public health care system with free access to specialized care, successful management of the majority of HIV patients is achievable. Interventions tailored to retain immigrants and injection drug users in care are needed to further reduce the proportion of sub-optimally treated HIV patients.

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.

Measuring retention in HIV care: the elusive gold standard

BACKGROUND

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.

METHODS

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.

RESULTS

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).

CONCLUSIONS

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.

Developing PeerLink to engage out-of-care HIV+ substance users: training peers to deliver a peer-led motivational intervention with fidelity

Substance use among HIV+ individuals can be a barrier to HIV care, resulting in poor health outcomes. Motivational interviewing (MI) is an effective intervention to reduce substance abuse and increase HIV-related health. Healthcare workers from various backgrounds can be effectively trained in delivering MI interventions; however, there has been limited evidence that peers can effectively deliver MI interventions with fidelity. Peers have traditionally worked in HIV care settings and represent a valid context for a peer-delivered intervention focused on motivational issues. We trained four peers in MI. In this paper, we describe the intervention, explain the MI training methods, and investigate whether peers can be trained in MI with fidelity. The MI training included didactic instruction, group workshops, and individual feedback sessions. Two of four peers achieved MI treatment fidelity as measured by the Motivational Interviewing Treatment Integrity Code Version 3.0. Overall, peers had difficulty using open-ended questions and querying pros and cons, skills thought necessary to elicit change talk. They also tended to give too much direct advice where reflections would have been appropriate. A challenge was training peers to change familiar ways of communicating. Nonetheless, they did well at assessing and highlighting motivation to change. The total training hours (40 h) was long compared with other published MI studies. However, the intervention included several components with two targeted change behaviors. It is likely that peers can be trained in MI with fidelity in less time given a more streamlined intervention. When working with peers who have life stressors similar to the target group, it is important to be flexible in the training.

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.

Dental case manager encounters: the association with retention in dental care and treatment plan completion

Little is known about dental case managers as few programs have been scientifically evaluated. The goal of this study was to explore the impact of dental case manager on retention in dental care and completion of treatment plans, while specifically exploring the number of dental case manager encounters. Fourteen programs enrolled people with HIV/AIDS (PLWHA) in dental care and a longitudinal study between 2007 and 2009. The 758 participants had a total of 2715 encounters with a dental case manager over twelve months: 29% had a single encounter; 21% had two; 27% had 3-4 and; 23% had 5-29 encounters. Adjusting for baseline characteristics, participants receiving more encounters were significantly more likely to complete their Phase 1 treatment plan, be retained in dental care, and experience improvements in overall oral health status. Organizations considering efforts to improve the oral health of vulnerable, hard-to-engage populations should consider these findings when planning interventions.

The outreach worker role in an anticipatory care programme: a valuable resource for linking and supporting

OBJECTIVES

Keep Well, an anticipatory care programme which commenced in Scotland in 2006, aims to reduce health inequalities through holistic health checks in primary care in deprived communities. A new, non-clinical outreach worker role was created to provide support and signposting to Keep Well patients following their health check. There is currently little evidence regarding how the role is perceived. The aim of this study was to understand how staff and patients view the Keep Well outreach worker role.

STUDY DESIGN

A qualitative interview-based study was carried out between July and October 2010.

METHODS

One-to-one interviews were conducted with 12 Keep Well staff and four patients. Interviews were transcribed, coded and analysed using a thematic analysis approach.

RESULTS

The outreach worker role was viewed positively, particularly in terms of partnership working with practices and local services, and the benefits of support to patients. Referring patients to outreach workers reduced pressure on staff, who were able to spend more time on patients' physical health rather than mental health or lifestyle support. Support from an outreach worker enabled patients to make changes to their life and their health. Concerns were about staff turnover, poor referral rates, set-up of the project and misinterpretation of the role.

CONCLUSION

Patients and staff perceive benefits from the outreach worker role in providing motivational support to patients from deprived areas.

Predictors of linkage to care following community-based HIV counseling and testing in rural Kenya

Despite innovations in HIV counseling and testing (HCT), important gaps remain in understanding linkage to care. We followed a cohort diagnosed with HIV through a community-based HCT campaign that trained persons living with HIV/AIDS (PLHA) as navigators. Individual, interpersonal, and institutional predictors of linkage were assessed using survival analysis of self-reported time to enrollment. Of 483 persons consenting to follow-up, 305 (63.2%) enrolled in HIV care within 3 months. Proportions linking to care were similar across sexes, barring a sub-sample of men aged 18-25 years who were highly unlikely to enroll. Men were more likely to enroll if they had disclosed to their spouse, and women if they had disclosed to family. Women who anticipated violence or relationship breakup were less likely to link to care. Enrollment rates were significantly higher among participants receiving a PLHA visit, suggesting that a navigator approach may improve linkage from community-based HCT campaigns.

Comparing different measures of retention in outpatient HIV care

OBJECTIVES

The US National HIV/AIDS Strategy identifies retention in care as an important quality performance measure. There is no gold standard to measure retention in care. This study is the first to compare different measures of retention, using a large geographically diverse sample.

DESIGN

A prospective cohort of 17,425 HIV-infected adults enrolled in care at 12 US HIV clinics between 2001 and 2008.

METHODS

We compared three measures of retention for each patient: proportion of time not spent in a gap of more than 6 months between successive outpatient visits; proportion of 91-day quarters in which at least one visit occurred; proportion of years in which two or more visits separated by at least 90 days occurred. Associations among measures and effects of sociodemographic and clinical characteristics were examined.

RESULTS

The three measures of retention were moderately to strongly correlated. Averaging across patients, 71% of time in care was not spent in a gap more than 6 months; 73% of all quarters had at least one visit; and 75% of all years had at least two visits separated by at least 90 days. For all measures, retention was significantly higher for women, whites, older individuals, men who had sex with men (MSM)-related HIV transmission, and initial CD4 cell counts 50 cell/μl or less.

CONCLUSIONS

This is one of the first studies to provide a national estimate of retention in HIV care in the US, which ranged from 71 to 75% using any of the accepted retention measures. Future studies should assess how well different measures predict clinical outcomes and establish acceptable target levels for retention.

The impact of retention in early HIV medical care on viro-immunological parameters and survival: a statewide study

Current literature on retention in HIV care fails to account for patients who continually/simultaneously access different providers. This statewide study examined retention in early HIV medical care and its impact on viro-immunological improvement and survival outcomes. It was a retrospective study of South Carolina residents ≥13 years old who were diagnosed with HIV infection in 2004-2007 and initially entered in care. CD4 count/percent and viral load (VL) tests that must be reported to the South Carolina HIV surveillance database were used as a proxy for a clinical visit. Retention was defined as at least one visit in each of four 6-month periods over 2 years postlinkage. Retention rates were categorized as "optimal" (visits in four intervals), "suboptimal" (visits in three intervals), sporadic (visits in two or one intervals), and "dropout" (no visits). Logistic regression and Cox proportional analyses were used to examine retention. Of the 2197 persons, about 50% failed to maintain optimal retention in care postlinkage. Male gender, nonwhite race/ethnicity, younger age, delayed linkage, and HIV-only status were significant predictors of lower rate of retention. Mean decrease in baseline log(10) VL was greater among those with optimal compared to suboptimal (-1.81 vs. -1.42; p < 0.001) and sporadic retention (-1.81 vs. -0.70; p < 0.001). Mean increase in baseline CD4 count was greater in optimal retention compared to suboptimal (169.70 vs. 107.5; p < 0.001) and sporadic retention (169.70 vs. 2.43; p < 0.001). Increased risk of mortality was associated with sporadic retention (aHR 2.91; 95% CI 1.54-5.50) and "dropout" (aHR 4.00; 95% CI 1.50-10.65). Rate of poor retention in early HIV medical care was relatively higher than reported in clinic-based data. Increasing the rate of retention in early HIV care could substantially improve viro-immunological parameters and survival outcomes.

Linkage to care for HIV-infected heterosexual men in the United States

In the United States, the human immunodeficiency virus (HIV) epidemic among heterosexual men disproportionately affects individuals involved with the criminal justice system, injection drug and other substance users, and racial and ethnic minorities. These overlapping populations confront similar social and structural disparities that contribute to HIV risk and limit access to HIV testing, treatment, and care. In this review, we discuss barriers to linkage to comprehensive HIV care for specific subpopulations of heterosexual men and examine approaches for enhancing linkage to care for this diverse population.

Improving HIV/AIDS care through treatment advocacy: going beyond client education to empowerment by facilitating client-provider relationships

Treatment advocacy (TA) programs have been implemented by AIDS service organizations (ASOs) and primary care clinics across the USA to help engage clients with HIV into care and support their adherence to antiretroviral therapy (ART). TA aims to empower people with HIV through education and client-centered counseling regarding HIV, ART, and other health issues; advocate on behalf of patients with providers; and make referrals to healthcare services and clinical trials. However, relatively little is known about the impact TA has on clients' healthcare experiences. The present study's objectives included exploring how TA services help clients engage in HIV care, initiate ART, and adhere to HIV medications. We conducted 25 semi-structured qualitative open-ended interviews with clients living with HIV/AIDS recruited from AIDS Project Los Angeles (APLA); four HIV medical providers; and two TA staff at APLA. Of the 25 clients interviewed, 92% were male and 8% were female. The average age was 43 years (SD=9). About 60% were African-American, 20% were White, 12% were other or multiracial, 4% were Latino, and 4% were Asian/Pacific Islander. Five interconnected themes consistently emerged across clients, TAs, and providers. TAs helped clients understand treatments and supported adherence within a holistic context. Further, TAs acted as a bridge to providers and helped clients build self-advocacy skills. Our data show that TA services go beyond traditional areas of education and treatment adherence. TA services within an ASO also provide a safe place to discuss initial HIV diagnoses and other health issues in a more comprehensive manner. TA services complemented medical and other social services by preparing clients with HIV to be better consumers of healthcare services. Future quantitative research examining the effectiveness of TA on improving clients' engagement in care and adherence is a critical next step.

Strategies to improve access to and utilization of health care services and adherence to antiretroviral therapy among HIV-infected drug users

We review five innovative strategies to improve access, utilization, and adherence for HIV-infected drug users and suggest areas that need further attention. In addition, we highlight two innovative programs. The first increases access and utilization through integrated HIV and opioid addiction treatment with buprenorphine in a community health center, and the second incorporates adherence counseling for antiretroviral therapy in methadone programs. Preliminary evaluations demonstrated that these strategies may improve both HIV and opioid addiction outcomes and may be appropriate for wider dissemination. Further refinement and expansion of strategies to improve outcomes of HIV-infected drug users is warranted.

Online and offline sexual health-seeking patterns of HIV-negative men who have sex with men

To inform health information targeting, we used cross-sectional data from 2577 HIV-negative MSM to identify groups of men who access similar sources. Offline, more men reported talking to a physician about HIV than about having sex with men; fewer than half attended a safer sex workshop. Online, men sought information primarily through Internet search engines, GLBT websites, or health websites. A latent class analysis identified four groups of health seekers: minimal health seekers, those who accessed online sources only, those who sought information mostly from health professionals, and those who sought information from diverse sources. Minimal health seekers, 9% of the sample, were the group of greatest concern. They engaged in unprotected anal sex with multiple partners but infrequently testing for HIV or sought sexual health information. By encouraging health seeking from diverse sources, opportunities exist to increase men's knowledge of HIV/STI prevention and, when necessary, access to medical care.

From access to engagement: measuring retention in outpatient HIV clinical care

Engagement in HIV care is increasingly recognized as a crucial step in maximizing individual patient outcomes. The recently updated HIV Medicine Association primary HIV care guidelines include a new recommendation highlighting the importance of extending adherence beyond antiretroviral medications to include adherence to clinical care. Beyond individual health, emphasis on a "test and treat" approach to HIV prevention highlights the public health importance of engagement in clinical care as an essential intermediary between the putative benefits of universal HIV testing ("test") followed by ubiquitous antiretroviral treatment ("treat"). One challenge to administrators, researchers and clinicians who want to systematically evaluate HIV clinical engagement is deciding on how to measure retention in care. Measuring retention is complex as this process includes multiple clinic visits (repeated measures) occurring longitudinally over time. This article provides a synthesis of five commonly used measures of retention in HIV care, highlighting their methodological and conceptual strengths and limitations, and suggesting situations where certain measures may be preferred over others. The five measures are missed visits, appointment adherence, visit constancy, gaps in care, and the Human Resources and Services Administration HIV/AIDS Bureau (HRSA HAB) performance measure for retention in HIV care. As has been noted for antiretroviral medication adherence, there is no gold standard to measure retention in care, and consideration of the advantages and limitations of each measure, particularly in the context of the desired application, should guide selection of a retention measure.

HIV testing factors associated with delayed entry into HIV medical care among HIV-infected persons from eighteen states, United States, 2000-2004

Despite the importance of timely entry into care after HIV diagnosis, the timing of care entry has not been described recently in a large, diverse population of persons with HIV. Dates of HIV diagnosis and entry into HIV care were obtained by interview of HIV-infected adults, most of whom had entered care for HIV, in 18 U.S. states from 2000 through 2004. Time to care entry was analyzed as a dichotomous variable; delayed care entry was defined as care entry greater than 3 months after HIV diagnosis. Multivariable logistic regression models were used to describe HIV testing-related factors associated with delayed care entry. Among 3942 respondents, 28% had delayed care entry. Diagnostic testing-related characteristics associated with delayed care entry included anonymous and first-time HIV testing. Providers of HIV testing should be aware that those who test positive anonymously and those whose first HIV test is positive may have increased risk for delayed HIV care entry. Developing programs that reinforce timely linkage to HIV care, targeted at those at increased risk for delaying care entry, should be a public health priority.
