PositiveLinks: A Mobile Health Intervention for Retention in HIV Care and Clinical Outcomes with 12-Month Follow-Up

Requirements and Key Features of a Mobile Application for Adolescent Self-Care From a Stakeholders Perspective: A Qualitative Study

Adolescence is characterized by many changes and these changes differentiate adolescents' self-care needs. The use of smartphones and tablets to provide healthcare services has expanded, and the user-centered design could help to create mobile applications based on users' needs. Therefore, the present study aimed to identify the data requirements and key features of mobile application for adolescent self-care from a stakeholder perspective. This study was conducted with a qualitative approach to identify the key features of mobile application for adolescent's self-care as well as educational content axes for five component of self-care using conventional and directed content analysis respectively. From 3 sub-groups 30 participants were selected based on purposive sampling with maximum variety and sampling was performed until data saturation. Data were collected through in-depth semi-structured interviews. Participants' informed consent was obtained before the interview. The interview lasted 20-40 min and MAXQDA software version 10 was used for data analysis. In this study, four criteria of acceptability, reliability, transferability, and validity proposed by Guba and Lincoln were used to evaluate and validate the data. After conducting the interviews, 789 initial codes, 12 sub-categories, and 3 categories (app view, app content architecture, app self-care content) were emerged, which reflects the key features of a mobile application and the necessary educational content. The research findings could provide a guide for future mobile application development considering the viewpoints of health professionals, content, and software experts. Addressing the features and requirements in practice could lead to designing efficient and effective mobile applications.

Operationalizing implementation science frameworks to plan a hybrid effectiveness-implementation study of a digital health intervention

Background

Evaluating implementation of digital health interventions (DHIs) in practice settings is complex, involving diverse users and multistep processes. Proactive planning can ensure desired implementation determinants and outcomes are captured for hybrid studies, but operational guidance for DHI studies is limited.

Methods

We planned a cluster randomized, type II hybrid effectiveness-implementation trial testing PositiveLinks, a smartphone application for HIV care, compared to usual care (n = 6 sites per arm), among HIV outpatient sites in the DC Cohort Longitudinal HIV Study in Washington, DC. Our process included: 1) Defining components of the DHI and associated implementation strategy, 2) Selecting implementation science frameworks to accomplish evaluation aims, 3) Mapping framework dimensions, domains, and constructs to implementation strategy steps, 4) Modifying/creating instruments to collect data for implementation outcome measures and determinants and 5) Developing a compatible implementation science data collection and management plan.

Results

Specification of components of the DHI and implementation strategy identified relevant platform usage data and necessary implementer actions, toward planning measurement of program reach and adoption. A priori mapping of implementation strategy steps to the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework identified how data would be collected for each step/corresponding outcome measure. The multi-site cohort study provided infrastructure for prospective, scaled implementation research, including site research assistants (RAs) coordinating implementation. Existing cohort tools (periodic site assessments, patient consent logs) were adapted for the evaluation to further capture representativeness and reach/adoption 'denominators.' New survey instruments allowed for framework-guided evaluation of provider adaptations/dose/fidelity to planned implementation across a large number of participants and multiple timepoints. Some aspects of real-world implementation were challenging to mirror within the planned hybrid trial (e.g. RAs selected as de facto site implementation leads) or were modified to preserve internal validity of effectiveness measurement (e.g. PositiveLinks 'community of practice').

Conclusions

Challenges and opportunities arose in planning the implementation evaluation for PositiveLinks within a hybrid trial in a cohort population. Prospective hybrid trial planning must balance generalizability of implementation processes to 'real world' conditions, with rigorous trial procedures to measure intervention effectiveness. Rapid, scalable tools require further study to enable evaluations within large, multi-site hybrid studies.

Effectiveness of interactive voice response-call for life mHealth tool on adherence to anti-retroviral therapy among young people living with HIV: A randomized trial in Uganda

INTRODUCTION

In people living with HIV, adherence to antiretroviral therapy (ART) is essential for achieving and sustaining viral suppression and reducing mortality. In young people living with HIV, ART adherence and retention remain a challenge with unsatisfactory viral suppression rates despite facility-based intensive adherence counseling that is the standard of care. Few studies have evaluated mHealth adherence interventions among young people living with HIV in resource-limited settings.

METHODS

This was a randomized parallel trial. Young people aged between15-24 living with HIV, initiating ART, or on ART for not more than 6 months at three ART clinics were recruited and randomized to a ratio of 1:1 to either standard of care or the intervention "Call for Life-Interactive Voice Response" with standard of care, between 12th August 2020 and 1st June 2022. The intervention is mobile technology-based software, that has interactive voice response functionalities, with a web-based interface, that allows interaction through the use of voice and tones via a dial pad. The primary outcome was viral suppression defined as HIV RNA below 1,000 copies per mL at 12 months with retention in care and viral suppression at month 6 as a secondary outcome. Descriptive statistics were used for participant characteristics. Primary outcomes and factors associated with viral load failure were assessed using the log-binomial model. All calculations were done using statistical software release 16.0.

RESULTS

A total of 206 participants were recruited and randomized; the mean age was 22.5(SD±1.9) years and 81% (167/206) were female. The intervention had 78.6% (81/103), females, while the standard of care had 83.5% (86/103). Viral suppression at 12 months in the intervention arm was 73.6% (67/91) versus 51.9% (40/77) in the standard of care arm, p=0.01. Retention in care was 88.4% (91/103) in the intervention vs. 74.7% (77/103) in the standard of care arm p=0.01.

CONCLUSION

This is the first study in Uganda to demonstrate that mHealth has the potential to improve medication adherence and retention in care among youth living with HIV in Uganda.

Acceptability of an online peer support group as a strategy to improve antiretroviral therapy adherence among young people in Kampala District, Uganda: qualitative findings

Introduction

Peer support groups may contribute to adherence and play a role in decreasing stigma to antiretroviral therapy (ART) adherence among young people living with HIV (YPLHIV). However, peer support activities usually occur face-to-face in Uganda and elsewhere in Sub-Saharan Africa, and thus have structural limitations and may not be readily available when young people need them. Online peer support has the potential to help YPLHIV access regular psychosocial support without significant effort or cost. We assessed the acceptability of a WhatsApp-based peer support group as a strategy to improve ART adherence among Ugandan YPLHIV.

Methods

We conducted a formative qualitative study in three health facilities in Kampala, Uganda, between July and August 2022. We held four focus group discussions with twenty-six YPLHIV seeking services at the study facilities. We also conducted six key informant interviews with health providers attached to adolescent HIV care clinics. The data was analyzed using thematic analysis guided by the acceptability framework to understand socio-cultural beliefs and perceptions towards utilizing WhatsApp-based peer support groups for HIV care.

Results

Overall, the peer support group on WhatsApp was acceptable for use among YPLHIV. The young people regarded it as convenient because it would save time and would be more cost-effective compared to the transport costs of in-person meetings. Health providers revealed that the WhatsApp peer support group could reduce the stigma associated with community follow-up for non-adhering young people and empower YPLHIV to overcome stigma. Both the young people and health providers suggested that online peer support could provide accessible emotional support, which could improve YPLHIV's psychosocial well-being and enhance adherence to ART. However, participants raised concerns about privacy, the cost of internet bundles, and smartphones, especially for younger adolescents.

Conclusion

Online peer support groups are acceptable to Ugandan YPLHIV and hold promise in enhancing psychosocial support and improving treatment adherence in this sub-population. In implementing online support groups, due consideration should be given to software tools with high privacy standards and zero-rated data use for new apps. Research is needed to evaluate the feasibility and effectiveness of this peer support model in Uganda.

Recommendations for the equitable integration of digital health interventions across the HIV care cascade

Gogishvili et al highlight the crucial role of digital health interventions (DHIs) in improving HIV care outcomes and experiences. They provide recommendations for the equitable integration of DHIs in the HIV care cascade, emphasizing the need to address the digital divide to ensure inclusive access to healthcare.

Identifying Motivators, Facilitators, and Barriers to Engagement and Retention in Anal Cancer Screening Among Men and Women with HIV in One Ryan White HIV/AIDS Clinic

Anal squamous cell carcinoma disproportionally affects people with HIV (PWH); however, engagement in anal cancer screening is low in many settings. This study was conducted to assess knowledge and perceptions of anal cancer screening to identify factors in the engagement and retention in prevention services among PWH. Semistructured interviews were conducted among adult PWH eligible for anal cancer screening in our Ryan White HIV/AIDS Program clinic. Descriptive statistics were tabulated; thematic analyses were performed to identify emerging motivators, facilitators, and barriers. Among 26 PWH, 9 had not been screened, 8 had undergone Papanicolaou (Pap) testing alone, and 9 had undergone anoscopy. The median age of the cohort was 55.2 years; 54% identified as men who have sex with men, and 54% identified as Black. In the unscreened cohort, participants were motivated by investing in their health and positive attitudes toward cancer prevention however were deterred by a lack of referral and low awareness about screening. Among those who had Pap testing, trust in healthcare providers and abnormal testing results were motivators to engagement, whereas lack of perceived risk of anal cancer and worry about pain of an anoscopy were prominent barriers. Among those who had anoscopy, perceived risk, positive experience with the procedure, and use of anxiolytics prior to anoscopy were motivators, whereas anxiety around a new cancer diagnosis and negative experience with anoscopy were barriers. Clinics seeking to build or strengthen their anal cancer screening programs can address the barriers described in this study to promote access to anal cancer screening among PWH.

User Engagement With mHealth Interventions to Promote Treatment Adherence and Self-Management in People With Chronic Health Conditions: Systematic Review

BACKGROUND

There are numerous mobile health (mHealth) interventions for treatment adherence and self-management; yet, little is known about user engagement or interaction with these technologies.

OBJECTIVE

This systematic review aimed to answer the following questions: (1) How is user engagement defined and measured in studies of mHealth interventions to promote adherence to prescribed medical or health regimens or self-management among people living with a health condition? (2) To what degree are patients engaging with these mHealth interventions? (3) What is the association between user engagement with mHealth interventions and adherence or self-management outcomes? (4) How often is user engagement a research end point?

METHODS

Scientific database (Ovid MEDLINE, Embase, Web of Science, PsycINFO, and CINAHL) search results (2016-2021) were screened for inclusion and exclusion criteria. Data were extracted in a standardized electronic form. No risk-of-bias assessment was conducted because this review aimed to characterize user engagement measurement rather than certainty in primary study results. The results were synthesized descriptively and thematically.

RESULTS

A total of 292 studies were included for data extraction. The median number of participants per study was 77 (IQR 34-164). Most of the mHealth interventions were evaluated in nonrandomized studies (157/292, 53.8%), involved people with diabetes (51/292, 17.5%), targeted medication adherence (98/292, 33.6%), and comprised apps (220/292, 75.3%). The principal findings were as follows: (1) >60 unique terms were used to define user engagement; "use" (102/292, 34.9%) and "engagement" (94/292, 32.2%) were the most common; (2) a total of 11 distinct user engagement measurement approaches were identified; the use of objective user log-in data from an app or web portal (160/292, 54.8%) was the most common; (3) although engagement was inconsistently evaluated, most of the studies (99/195, 50.8%) reported >1 level of engagement due to the use of multiple measurement methods or analyses, decreased engagement across time (76/99, 77%), and results and conclusions suggesting that higher engagement was associated with positive adherence or self-management (60/103, 58.3%); and (4) user engagement was a research end point in only 19.2% (56/292) of the studies.

CONCLUSIONS

The results revealed major limitations in the literature reviewed, including significant variability in how user engagement is defined, a tendency to rely on user log-in data over other measurements, and critical gaps in how user engagement is evaluated (infrequently evaluated over time or in relation to adherence or self-management outcomes and rarely considered a research end point). Recommendations are outlined in response to our findings with the goal of improving research rigor in this area.

HIV and Substance Use Disorders

Over 1.2 million Americans aged 13 years and older have been diagnosed with human immunodeficiency virus (HIV). While HIV incidence has been declining since 2017, the risk of HIV acquisition and transmission persists among persons who use drugs via injection drug use and unprotected sexual intercourse associated with substance use. Untreated substance use disorder (SUD) is associated with poor adherence to HIV antiretroviral therapy, poor HIV outcomes, and increased risk for HIV acquisition. Herein, we describe the intertwined syndemic of HIV and SUD, as well as treatment strategies and evidence-based public health efforts to engage and retain persons who use drugs into care.

Three-Year Follow-up of PositiveLinks: Higher Use of mHealth Platform Associated with Sustained HIV Suppression

PositiveLinks (PL) is a mHealth platform to support care engagement by people with HIV (PWH). Daily reminders prompt the user to report medication adherence, mood, and daily stress. Higher response rate to PL check-ins has been associated with better suppression of viral load over 6-18 months. We conducted a retrospective chart review for a three-year period collecting demographic information, average mood and stress scores, and all viral loads obtained in usual patient care. We performed multivariable logistic regression modeling to identify factors associated with loss of viral load suppression and a time-to-event survival analysis until first unsuppressed viral load stratified by PL usage. Of the 513 PWH included, 103 had at least one episode of viral non-suppression. Low users of PL were more likely to have an unsuppressed viral load with an adjusted Odds Ratio (aOR) of 5.8 (95% CI 3.0-11.5, p < 0.001). Protective factors included older age (aOR 0.96; 95% CI 0.93-0.98, p = 0.003) and income above the federal poverty level (FPL) (aOR 0.996; 95% CI 0.995-0.998, p < 0.001). High PL use was also associated with better viral load suppression (VLS) over time (p < 0.0001 ((aHR) of 0.437 (95% CI 0.290-0.658, p < 0.001)) after adjusting for age and FPL. High stress scores were related to subsequent loss of viral suppression in an exploratory analysis. High check-in response rate on the PL app, older age, and higher income are associated with sustained VLS over time. Conversely, lack of response to check-ins or increased reported stress may signal a need for additional support.

Increasing linkage to hepatitis C care following trauma-informed rehabilitation: An education and quality improvement project among women

INTRODUCTION

The on-going substance use crisis has led to unprecedented rates of hepatitis C virus (HCV) in Canada, with increasing positivity among women who use drugs (WWUD). Despite efforts to reduce barriers to HCV testing and treatment, follow-up remains a major issue.

METHODS

In this quality improvement project (QIP), we partnered with a short-stay trauma-informed residential drug treatment facility specifically for WWUD, to provide an engaging peer-led HCV education session, followed by low-barrier nurse and peer-led testing and treatment. We sought to evaluate these interventions, as well as determine what factors could improve engagement after women leave.

RESULTS

The session was attended by 217 participants, 130 completed the survey and 153 opted into testing. Survey results indicated that participants were highly motivated to access general care as well as HCV testing and treatment. The most frequently reported barriers to testing and treatment were a previous negative test and being asymptomatic, respectively. Follow-up facilitators included a non-judgmental provider (88%), monetary incentives (67%), follow-up phone calls (77%), e-mails (66%) and text messages (58%). Of those who were RNA positive, 5 of 13 initiated treatment on-site. By using the results of the QIP in real-time, 6 of 13 were started after leaving the centre (one pending and one lost to follow-up).

DISCUSSION AND CONCLUSIONS

The implementation of co-localised peer-led testing and treatment for HCV, along with persistent follow-up efforts, led to increases in linkage to care and treatment. Co-localisation of testing and care with substance-use services, especially if residential, is a viable, low-barrier strategy for increasing linkage to care among WWUD.

Patient Perspectives on Portal-Based Anxiety and Depression Screening in HIV Care: A Qualitative Study Using the Consolidated Framework for Implementation Research

Electronic patient portals represent a promising means of integrating mental health assessments into HIV care where anxiety and depression are highly prevalent. Patient attitudes toward portal-based mental health screening within HIV clinics have not been well described. The aim of this formative qualitative study is to characterize the patient-perceived facilitators and barriers to portal-based anxiety and depression screening within HIV care in order to inform implementation strategies for mental health screening. Twelve adult HIV clinic patients participated in semi-structured interviews that were audio recorded and transcribed. The transcripts were coded using constructs from the Consolidated Framework for Implementation Research and analyzed thematically to identify the barriers to and facilitators of portal-based anxiety and depression screening. Facilitators included an absence of alternative screening methods, an approachable design, perceived adaptability, high compatibility with HIV care, the potential for linkage to treatment, an increased self-awareness of mental health conditions, the ability to bundle screening with clinic visits, and communicating an action plan for results. The barriers included difficulty navigating the patient portal system, a lack of technical support, stigmatization from the healthcare system, care team response times, and the novelty of using patient portals for communication. The patients in the HIV clinic viewed the use of a portal-based anxiety and depression screening tool as highly compatible with routine HIV care. Technical difficulties, follow-up concerns, and a fear of stigmatization were commonly perceived as barriers to portal use. The results of this study can be used to inform implementation strategies when designing or incorporating portal-based mental health screening into other HIV care settings.

A Call for Youth Voice to Support Engagement in Care for 18- to 29-Year Olds Living with HIV in the US South

Youth with HIV (YWH) face challenges in achieving viral suppression, particularly in the Southern United States, and welcome novel interventions responsive to community needs. The Theory of Planned Behavior (TPB) describes factors that influence behavior change, and the Positive Youth Development (PYD) supports youth-focused program design. We applied TPB and PYD to explore factors supporting care engagement and challenges for YWH in South Texas. We conducted 14 semi-structured interviews with YWH and 7 focus groups with 26 stakeholders informed by TPB, PYD, and themes from a youth advisory board (YAB). The research team and YAB reviewed emerging themes, and feedback-aided iterative revision of interview guides and codebook. Thematic analysis compared code families by respondent type, TPB, and PYD. All study methods were reviewed by the UT Health San Antonio and University Health Institutional Review Boards. Emerging themes associated with care engagement included: varied reactions to HIV diagnosis from acceptance to fear/grief; financial, insurance, and mental health challenges; history of trauma; high self-efficacy; desire for independence; and desire for engagement with clinic staff from their age group. Stakeholders perceived YWH lifestyle, including partying and substance use, as care barriers. In contrast, YWH viewed "partying" as an unwelcome stereotype, and barriers to care included multiple jobs and family responsibilities. Two key themes captured in PYD but not in TPB were the importance of youth voice in program design and structural barriers to care (e.g., insurance, transportation). Based on these findings, we provide critical and relevant guidance for those seeking to design more effective youth-centered HIV care engagement interventions. By considering the perspectives of YWH in program design and incorporating the PYD framework, stakeholders can better align with YWHs' desire for representation and agency. Our findings provide important and relevant guidance for those seeking to design more effective HIV care engagement interventions for YWH.

Consolidated guidance for behavioral intervention pilot and feasibility studies

BACKGROUND

In the behavioral sciences, conducting pilot and/or feasibility studies (PFS) is a key step that provides essential information used to inform the design, conduct, and implementation of a larger-scale trial. There are more than 160 published guidelines, reporting checklists, frameworks, and recommendations related to PFS. All of these publications offer some form of guidance on PFS, but many focus on one or a few topics. This makes it difficult for researchers wanting to gain a broader understanding of all the relevant and important aspects of PFS and requires them to seek out multiple sources of information, which increases the risk of missing key considerations to incorporate into their PFS. The purpose of this study was to develop a consolidated set of considerations for the design, conduct, implementation, and reporting of PFS for interventions conducted in the behavioral sciences.

METHODS

To develop this consolidation, we undertook a review of the published guidance on PFS in combination with expert consensus (via a Delphi study) from the authors who wrote such guidance to inform the identified considerations. A total of 161 PFS-related guidelines, checklists, frameworks, and recommendations were identified via a review of recently published behavioral intervention PFS and backward/forward citation tracking of a well-known PFS literature (e.g., CONSORT Ext. for PFS). Authors of all 161 PFS publications were invited to complete a three-round Delphi survey, which was used to guide the creation of a consolidated list of considerations to guide the design, conduct, and reporting of PFS conducted by researchers in the behavioral sciences.

RESULTS

A total of 496 authors were invited to take part in the three-round Delphi survey (round 1, N = 46; round 2, N = 24; round 3, N = 22). A set of twenty considerations, broadly categorized into six themes (intervention design, study design, conduct of trial, implementation of intervention, statistical analysis, and reporting) were generated from a review of the 161 PFS-related publications as well as a synthesis of feedback from the three-round Delphi process. These 20 considerations are presented alongside a supporting narrative for each consideration as well as a crosswalk of all 161 publications aligned with each consideration for further reading.

CONCLUSION

We leveraged expert opinion from researchers who have published PFS-related guidelines, checklists, frameworks, and recommendations on a wide range of topics and distilled this knowledge into a valuable and universal resource for researchers conducting PFS. Researchers may use these considerations alongside the previously published literature to guide decisions about all aspects of PFS, with the hope of creating and disseminating interventions with broad public health impact.

Implementation of free-draft text messaging to enhance care retention and satisfaction for persons living with HIV infection

Eligible persons with HIV infection can receive client-centered case management to coordinate medical and social services. Novel mobile health interventions could improve effective case management and retention in care, an important goal to help end the HIV epidemic. Using a hybrid type I effectiveness-implementation design, we assessed whether access to bidirectional, free-draft secure text messaging with a case manager and clinic pharmacist could improve client satisfaction and care retention in a Southern academic HIV clinic. Sixty-four clients enrolled between November 2019 and March 2020, had a median age of 39 years, and were mostly male, single, and African-American. Heavy app users texted over 100 times (n = 6) over the course of the 12-month intervention while others never texted (n = 12). App usage peaked during months of clinic closure due to COVID-19. Most participants reported high satisfaction with the app and planned continued usage after study completion. Changes in clinic retention and virologic suppression rates were not observed, a result confounded by practice changes due to COVID-19. High usage and satisfaction of free-draft text messaging in case-managed HIV clients supports inclusion of this communication option in routine HIV clinical care.

Changes in Adherence and Viral Load Suppression Among People with HIV in Manila: Outcomes of the Philippines Connect for Life Study

The Philippines HIV epidemic is among the fastest growing globally. Infections among men who have sex with men are rising at an alarming rate, necessitating targeted evidence-based interventions to retain people living with HIV in care, support adherence, and reach viral suppression. We conducted a 48-week prospective cohort study of 462 participants in which we provided a mobile health (mHealth) adherence support intervention using the Connect for Life platform. We observed an improvement in adherence, with the proportion of participants taking more than 95% of their antiretroviral therapy (ART) doses increasing from 78.6% at baseline to 90.3% at 48 weeks. Among treatment experienced participants, adherence improved significantly (McNemar's test = 21.88, P < 0.001). Viral load suppression did not change, with 92.6% suppression at baseline and 92.0% at 48 weeks. Illicit drug use was associated with reduced adherence (aOR = 0.56, 95%CI 0.31-1.00, P = 0.05) and being on second-line therapy was associated with poor viral load suppression (aOR = 0.33, 95%CI 0.14-0.78, P = 0.01). Quality of life improved following ART initiation, from a mean of 84.6 points (of a possible 120) at baseline to 91.01 at 48 weeks. Due to technical issues, fidelity to the intended intervention was low, with 22.1% (102/462) of participants receiving any voice calls and most others receiving a scaled-back SMS intervention. The mHealth intervention did not have any observed effect on adherence or on viral load suppression. While evidence of effectiveness of mHealth adherence interventions is mixed, these platforms should continue to be explored as part of differentiated treatment support services.

Nothing About Us Without Us: Involving Youth Living With HIV in a Virtual Advisory Board

PURPOSE

We adapted a traditional community advisory board to the needs of youth living with HIV (YLWH), resulting in a virtual, asynchronous, and anonymous youth advisory board (YAB). The YAB's evolution fostered participation during the adaptation of an HIV care mobile health application.

METHODS

YAB members, comprised of YLWH in South Texas, engaged in the mobile application's formative evaluation, adaptation, and pilot implementation. We collected feedback via surveys and interviews, analyzed and integrated responses, tracked participation and YAB adaptations, and performed content analysis.

RESULTS

Driven by feedback, the YAB evolved from in-person group meetings to the current iteration. We administered five surveys, and YAB members provided feedback on communication preferences; mobile app elements; privacy and confidentiality; and virtual support groups.

DISCUSSION

Our adaptive process highlights three primary drivers of innovation: COVID-19 risk reduction, asynchrony, anonymity. Our success in maintaining YAB engagement suggests the adapted model could be employed to support youth input in other contexts.

Examining Ethnic Disparities in Digital Healthcare Services Utilization: Insights from Israel

Purpose

The purpose of this study was to examine ethnic disparities in the utilization of digital healthcare services (DHS) in Israel and explore the characteristics and factors influencing DHS use among the Arab minority and Jewish majority populations.

Methods

A cross-sectional correlational design was employed to collect data from 606 Israeli participants, 445 Jews, and 161 Arabs. Participants completed a digital questionnaire that assessed DHS utilization, digital health literacy, attitudes towards DHS, and demographic variables.

Results

The findings reveal significant disparities in DHS utilization and attitudes between these ethnic groups, with Jewish participants demonstrating higher rates of utilization and positive attitudes toward DHS. The study also explores the predictive role of digital health literacy and attitudes in DHS use while considering ethnicity as a potential moderator. Significant predicting factors related to DHS utilization among Jews include positive attitudes and high health literacy. Among the Arabs, only attitudes towards DHS significantly predict the extent of DHS use. Digital health literacy affects the extent of use through attitudes at the two groups of the moderator significantly, but it is stronger among the Arab group.

Conclusion

To improve healthcare outcomes and reduce disparities, efforts should focus on ensuring equitable access to DHS for the Arab minority population. Targeted interventions, including digital literacy education, removing technology access barriers, offering services in Arabic, and collaborating with community organizations, can help bridge the gap and promote equal utilization of DHS.

Mobile health supported multi-domain recovery trajectories after major arthroplasty or spine surgery: a pilot feasibility and usability study

BACKGROUND

Recovery after surgery intersects physical, psychological, and social domains. In this study we aim to assess the feasibility and usability of a mobile health application called PositiveTrends to track recovery in these domains amongst participants undergoing hip, knee arthroplasty or spine surgery. Our secondary aim was to generate procedure-specific, recovery trajectories within the pain and medication, psycho-social and patient-reported outcomes domain.

METHODS

Prospective, observational study in participants greater than eighteen years of age. Data was collected prior to and up to one hundred and eighty days after completion of surgery within the three domains using PositiveTrends. Feasibility was assessed using participant response rates from the PositiveTrends app. Usability was assessed quantitatively using the System Usability Scale. Heat maps and effect plots were used to visualize multi-domain recovery trajectories. Generalized linear mixed effects models were used to estimate the change in the outcomes over time.

RESULTS

Forty-two participants were enrolled over a four-month recruitment period. Proportion of app responses was highest for participants who underwent spine surgery (median = 78, range = 36-100), followed by those who underwent knee arthroplasty (median = 72, range = 12-100), and hip arthroplasty (median = 62, range = 12-98). System Usability Scale mean score was 82 ± 16 at 180 days postoperatively. Function improved by 8 and 6.4 points per month after hip and knee arthroplasty, respectively. In spine participants, the Oswestry Disability Index decreased by 1.4 points per month. Mood improved in all three cohorts, however stress levels remained elevated in spine participants. Pain decreased by 0.16 (95% Confidence Interval: 0.13-0.20, p < 0.001), 0.25 (95% CI: 0.21-0.28, p < 0.001) and 0.14 (95% CI: 0.12-0.15, p < 0.001) points per month in hip, knee, and spine cohorts respectively. There was a 10.9-to-40.3-fold increase in the probability of using no medication for each month postoperatively.

CONCLUSIONS

In this study, we demonstrate the feasibility and usability of PositiveTrends, which can map and track multi-domain recovery trajectories after major arthroplasty or spine surgery.

Integrated Care Models: HIV and Substance Use

PURPOSE OF REVIEW

Behaviors and practices associated with substance use contribute to lack of HIV virologic suppression and onward transmission. In the USA, many recent HIV outbreaks have been connected with substance use. Evidence-based strategies for integrating care of those at risk for and living with HIV and who use substances continue to evolve. This review, based on scientific and medical literature through March 2023, provides an overview and evaluation of initiatives for integrated care aimed to serve patients at risk for and with HIV and a substance use disorder.

RECENT FINDINGS

Integrated care services can improve health outcomes for patients at risk for and with HIV and a substance use disorder; for instance, treatment for an opioid use disorder can help improve HIV viral suppression. Brick-and-mortar facilities can provide successful care integration with appropriate clinic leadership to support multidisciplinary care teams, up-to-date provider training, and sufficient pharmacy stock for substance use treatment. Delivering healthcare services to communities (e.g., mobile healthcare clinics and pharmacies, telehealth) may prove to be an effective way to provide integrated services for those with or at risk of HIV and substance use disorders. Incorporating technology (e.g., mobile phone applications) may facilitate integrated care. Other venues, including harm reduction programs and carceral settings, should be targets for integrated services. Venues providing healthcare should invest in integrated care and support legislation that increases access to services related to HIV and substance use.

An mHealth Platform for People With HIV Receiving Care in Washington, District of Columbia: Qualitative Analysis of Stakeholder Feedback

BACKGROUND

HIV viral suppression and retention in care continue to be challenging goals for people with HIV in Washington, District of Columbia (DC). The PositiveLinks mobile app is associated with increased retention in care and viral load suppression in nonurban settings. The app includes features such as daily medication reminders, mood and stress check-ins, an anonymized community board for peer-to-peer social support, secure messaging to care teams, and resources for general and clinic-specific information, among other features. PositiveLinks has not been tailored or tested for this distinct urban population of people with HIV.

OBJECTIVE

This study aimed to inform the tailoring of a mobile health app to the needs of people with HIV and their providers in Washington, DC.

METHODS

We conducted a 3-part formative study to guide the tailoring of PositiveLinks for patients in the DC Cohort, a longitudinal cohort of >12,000 people with HIV receiving care in Washington, DC. The study included in-depth interviews with providers (n=28) at study clinics, focus groups with people with HIV enrolled in the DC Cohort (n=32), and a focus group with members of the DC Regional Planning Commission on Health and HIV (COHAH; n=35). Qualitative analysis used a constant comparison iterative approach; thematic saturation and intercoder agreement were achieved. Emerging themes were identified and grouped to inform an adaptation of PositiveLinks tailored for patients and providers.

RESULTS

Emerging themes for patients, clinic providers, and COHAH providers included population needs and concerns, facilitators and barriers to engagement in care and viral suppression, technology use, anticipated benefits, questions and concerns, and suggestions. DC Cohort clinic and COHAH provider interviews generated an additional theme: clinic processes. For patients, the most commonly discussed potential benefits included improved health knowledge and literacy (mentioned n=10 times), self-monitoring (n=7 times), and connection to peers (n=6 times). For providers, the most common anticipated benefits were improved communication with the clinic team (n=21), connection to peers (n=14), and facilitation of self-monitoring (n=11). Following data review, site principal investigators selected core PositiveLinks features, including daily medication adherence, mood and stress check-ins, resources, frequently asked questions, and the community board. Principal investigators wanted English and Spanish versions depending on the site. Two additional app features (messaging and documents) were selected as optional for each clinic site. Overall, 3 features were not deployed as not all participating clinics supported them.

CONCLUSIONS

Patient and provider perspectives of PositiveLinks had some overlap, but some themes were unique to each group. Beta testing of the tailored app was conducted (August 2022). This formative work prepared the team for a cluster randomized controlled trial of PositiveLinks' efficacy. Randomization of clinics to PositiveLinks or usual care occurred in August 2022, and the randomized controlled trial launched in November 2022.

Interviews with HIV Experts for Development of a Mobile Health Application in HIV Care-A Qualitative Study

The Communication and Tracing App HIV (COMTRAC-HIV) project aims to develop a mobile health application for integrated care of HIV patients due to the low availability of those apps in Germany. This study addressed organizational conditions and necessary app functionalities, especially for the care of late diagnosed individuals (late presenters) and those using pre-exposure prophylaxis. We followed a human-centered design approach and interviewed HIV experts in Germany to describe the context of use of the app. The interviews were paraphrased and analyzed with a qualitative content analysis. To define the context of use, user group profiles were defined and tasks derived, which will represent the functionalities of the app. A total of eight experts were included in the study. The results show that the app should include a symptom diary for entering symptoms, side effects, and their intensity. It offers chat/video call functionality for communication with an HIV expert, appointment organization, and sharing findings. The app should also provide medication overview and reminders for medications and appointments. This qualitative study is a first step towards the development of an app for HIV individuals in Germany. Further research includes involving patients in the initial app design and test design usability.

Implementation of Low-Barrier Human Immunodeficiency Virus Care: Lessons Learned From the Max Clinic in Seattle

Low-barrier care (LBC) for people with human immunodeficiency virus (HIV) is a differentiated service delivery strategy to engage people in HIV treatment who are not well-engaged in conventionally organized HIV medical care. The LBC approach is flexible, but experience suggests that the intervention has distinct core components. This review summarizes our experience implementing one model of LBC, the Max Clinic in Seattle; describes the core components of the intervention; and presents a framework for implementing low-barrier HIV care with the goal of providing a practical guide for clinical and public health leaders seeking to implement a new LBC program. A systematic approach to addressing key factors during LBC implementation can support practitioners to design an LBC approach that fits the local context while maintaining essential elements of the intervention.

Prioritization of Evidence-Based and Evidence-Informed Interventions for Retention in Medical Care for Persons with HIV

Up to 50% of those diagnosed with HIV in the U.S. are not retained in medical care. Care retention provides opportunity to monitor benefits of HIV therapy and enable viral suppression. To increase retention, there is a need to prioritize best practices appropriate for translation and dissemination for real-world implementation. Eighteen interventions from CDC's Compendium of Evidence-Based Interventions were scored using the RE-AIM framework to determine those most suitable for dissemination. A CDC Division of HIV Prevention workgroup developed a RE-AIM scale with emphasis on the Implementation and Maintenance dimensions and less emphasis on the Efficacy dimension since all 18 interventions were already identified as evidence-based or evidence-informed. Raters referenced primary efficacy publications and scores were averaged for a ranked RE-AIM score for interventions. Of 18 interventions, four included care linkage and 7 included viral suppression outcomes. Interventions received between 20.6 and 35.3 points (45 maximum). Scores were converted into a percentage of the total possible with ranges between 45.8 and 78.4%. Top four interventions were ARTAS (78.4%); Routine Screening for HIV (RUSH) (73.2%); Optn4Life (67.4%) and Virology Fast Track (65.9%). All four scored high on Implementation and Maintenance dimensions. Select items within the scale were applicable to health equity, covering topics such as reaching under-served focus populations and acceptability to that population. Navigation-enhanced Case Management (NAV) scored highest on the health equity subscale. RE-AIM prioritization scores will inform dissemination and translation efforts, help clinical staff select feasible interventions for implementation, and support sustainability for those interventions.

The Black women first initiative: using implementation science to examine bundled interventions to improve care and treatment coordination for Black women with HIV

BACKGROUND

Black cisgender and transgender women are disproportionately affected by the HIV epidemic compared to women of other racial and ethnic identities. Twelve demonstration sites across the United States are adapting, implementing and evaluating a comprehensive bundle of two or more evidence informed interventions to improve health and outcomes and quality of life for Black women with HIV.

METHODS

Guided by Greenhalgh's Conceptual Model of Diffusion of Innovations in Health Service Organizations and Proctor's model for use of implementation strategies and evaluating implementation, service and client outcomes, this mixed methods study documents outcomes at the client, organization, and system level. Participant eligibility for the bundled interventions includes: individuals who are 18 years or older, identify as Black or African-American, identify as cisgender or transgender female and have a diagnosis of HIV. Qualitative data are collected systematically through a series of annual site visits and a standardized monthly call form to assess the barriers and facilitators to the implementation process and the key determinants impacting the intervention uptake and implementation strategies. Quantitative data collection for the implementation, service and client outcomes is conducted through a pre-post prospective study to examine the impact on Black women's health and well-being. Implementation outcomes include: the reach to Black women with HIV, adoption of interventions across the sites and their community; the fidelity to the components of the bundled interventions; the costs of the intervention; and the sustainability of the intervention in the organization and community. Primary service and client outcomes are improved linkage to and retention in HIV care and treatment, increased and sustained viral suppression, improved quality of life and resilience, and stigma reduction.

DISCUSSION

The study protocol presented is specifically designed to advance the evidence for adopting culturally responsive and relevant care into clinic and public health settings to improve the health and well-being for Black women with HIV. In addition the study may advance the implementation science field by furthering what is known about the ways in which bundled interventions can address barriers to care and facilitate the uptake of organizational practices to improve health.

A virtual pilot optimization trial for African American/Black and Latino persons with non-suppressed HIV viral load grounded in motivational interviewing and behavioral economics

Introduction

Virtual and low-touch behavioral interventions are needed for African American/Black and Latino persons living with HIV (PLWH) with barriers to HIV viral suppression, particularly during COVID-19. Guided by the multiphase optimization strategy, we explored three components for PLWH without viral suppression, grounded in motivational interviewing and behavioral economics: (1) motivational interviewing counseling, (2) 21-weeks of automated text messages and quiz questions about HIV management, and (3) financial rewards for viral suppression (lottery prize vs. fixed compensation).

Methods

This pilot optimization trial used sequential explanatory mixed methods to explore the components' feasibility, acceptability, and preliminary evidence of effects using an efficient factorial design. The primary outcome was viral suppression. Participants engaged in baseline and two structured follow-up assessments over an 8-month period, and provided laboratory reports to document HIV viral load. A subset engaged in qualitative interviews. We carried out descriptive quantitative analyses. Then, qualitative data were analyzed using directed content analysis. Data integration used the joint display method.

Results

Participants (N = 80) were 49 years old, on average (SD = 9), and 75% were assigned male sex at birth. Most (79%) were African American/Black, and the remainder were Latino. Participants were diagnosed with HIV 20 years previously on average (SD = 9). Overall, components were feasible (>80% attended) and acceptability was satisfactory. A total of 39% (26/66) who provided laboratory reports at follow-up evidenced viral suppression. Findings suggested no components were entirely unsuccessful. The lottery prize compared to fixed compensation was the most promising component level. In qualitative analyses, all components were seen as beneficial to individual wellbeing. The lottery prize appeared more interesting and engaging than fixed compensation. However, structural barriers including financial hardship interfered with abilities to reach viral suppression. The integrated analyses yielded areas of convergence and discrepancy and qualitative findings added depth and context to the quantitative results.

Conclusions

The virtual and/or low-touch behavioral intervention components tested are acceptable and feasible and show enough potential to warrant refinement and testing in future research, particularly the lottery prize. Results must be interpreted in the context of the COVID-19 pandemic.

Effectiveness of Program to Slow Progression of Chronic Kidney Disease Among T2DM With HT With CKD 3 in the Community: A Randomized Controlled Trial

Chronic kidney disease (CKD) is a significant threat to the quality of life of the global population. Thus, slowing kidney disease progression is considered vital in the treatment of CKD patients. The study aimed to evaluate the effectiveness of a program designed to slow the progression of CKD among Type 2 diabetes mellitus patients with HT with stage 3 CKD (CKD 3) in Thailand by adopting the information-motivation-behavioral skills (IMB) model and applying technology. This study was conducted as a cluster randomized controlled trial. The program activities comprised: (i) providing disease information and teaching behaviors to slow the progression of kidney disease to patients and family members via a 2-h session; (ii) teaching practical behavioral skills for appropriate diet and exercise to patients and family members via a 2-h session; (iii) enhancing personal motivation via the Line application and motivational interviewing via telephone calls; (iv) enhancing social motivation with the support of a family member; (v) employing technology to monitor behaviors and increase patient motivation; and (vi) assessing behaviors that were not practical, exploring barriers to behavior modification, and teaching further practical behavioral skills via the Line application. The data were analyzed using percentages, means, standard deviations, chi-square tests, t-tests, and a 2-way repeated-measures analysis of variance. The results showed that after the experiment, the experimental group had significantly higher mean scores in terms of knowledge, perceived benefits, perceived severity, self-efficacy, and behaviors to slow the progression of kidney disease than the control group (P < .05). Further, the experimental group had significantly better clinical outcomes (SBP, DBP, eGFR, BUN, creatinine, albuminuria, FBS, and HbA1c) than the control group (P < .05). In summary, the findings indicate that the program improved clinical outcomes, especially kidney function, effectively slowing the progression of kidney disease.

Positive Health Check intervention tool usage during a feasibility pilot in HIV primary care clinics

Positive Health Check (PHC), an interactive, web-based intervention, provides tailored behavioral health messages to support people with HIV in their HIV care. Users interact with a virtual doctor and based on responses to tailoring questions, PHC delivers relevant content modules addressing treatment initiation, medication adherence, retention in care, sexual risk reduction, mother-to-child transmission, and injection drug use. During a one-month feasibility pilot of PHC, patients in four HIV primary care clinics were invited to use PHC and tool usage metrics were collected and assessed. Descriptive analyses were conducted to characterize how the tool was used based on behavioral risk scenarios presented.Ninety-seven patients accessed PHC as part of the pilot, with 68 (70.1%) completing the intervention on average in 15 min. Out of 85 patients who viewed behavioral tips and commitments, 66 (77.7%) selected at least one tip to practice and 41 (48.2%) made at least one commitment to ask their provider a question. Patients spent the most time with adherence and sexual risk reduction content. The high level of tool engagement suggests that PHC was acceptable to patients regardless of length of time since diagnosis. PHC can be completed within a single visit and is a promising tool for PWH.

Feasibility and usability of a personalized mHealth app for self-management in the first year following breast cancer surgery

This study investigated the feasibility and usability of a personalized mobile health (mHealth) app for self-management during the year following breast cancer surgery. Twenty-nine participants were instructed to use an app and smart band immediately after discharge. Only 18 completed the study. Their perceived necessity and satisfaction for main domains and app were assessed at 1, 2, 4, 6, 9, and 12 months. A self-reporting questionnaire assessed usability at 12 months. Consequently, retention rate as measures of feasibility showed a mean of 75.8%. Exercise and diet management were the most accessed app domains. Perceived necessity was higher than satisfaction. The mean usability score was 80.2. Most participants found the app useful and effective as a delivery for healthcare. Further, 94% of them were willing to pay for and recommend it. Thus, mHealth app can help breast cancer patients improve their healthy behaviors and healthcare further. This study provides insights for designing long-term randomized controlled trials using mHealth interventions.

Use of a Mobile Health Intervention by Older Versus Younger People with HIV: Analysis of Usage, Social Support, and Network Interactions

BACKGROUND

People with HIV in the United States are aging, with risk for negative health outcomes from social isolation. PositiveLinks is a mobile health (mHealth) intervention that includes an anonymous Community Message Board (CMB) for peer-to-peer conversations. We investigated differences in CMB usage and social support between younger (<50 years) and older (≥50) members.

METHODS

We assessed the relationship between age groups and app use using chi-square tests. CMB posts were analyzed qualitatively to categorize forms of social support. To have a visual understanding of this relationship, we created a network diagram to display interactions among PL members.

RESULTS

Among 87 participants, 31 (42.5%) were in the older age group. Older members launched the app more often at 6 months (445.5 vs. 240.5 mean launches per participant, p ≤ 0.001) and 12 months (712.3 vs. 292.6 launches, p ≤ 0.001) compared with younger members. Older members also demonstrated more CMB posts at 6 months (47.4 vs. 7.6 mean posts per participant, p = 0.02) and 12 months (77.5 vs. 10.6 posts, p = 0.04). Of 1861 CMB posts, 7% sought support and 72% provided support. In addition, the network visualization showed that four participants, who were in the older age group, had more post generation than others and most of their posts provided support.

CONCLUSIONS

Older PL members demonstrated significantly more app use than younger members, including CMB posts for social support. This durable app engagement indicates that mHealth can enable social connection among people living with chronic disease across the lifespan.

Linkage to care and treatment among men with reactive HIV self-tests after workplace-based testing in Uganda: A qualitative study

Introduction

HIV self-testing at workplaces has the potential to reach men at risk of HIV infection with lower access to HIV testing services. While several studies have reported high uptake of HIV self-testing, linkage to HIV care following a positive result remains a challenge. This study, therefore, explored the motivators for and barriers to linkage to HIV care and treatment among men who returned positive results following workplace-based HIV self-testing.

Methods

A qualitative descriptive study, among men in private security services in Kampala district, Uganda. The men were eligible to participate if they were aged 18 to 60 years and had worked at the company for more than 6 months. Following HIV self-testing, participants with reactive (positive) self-test results were purposively sampled and engaged in key informant interviews. Inductive content analysis was employed to identify the motivators and barriers to the men's linkage to HIV treatment and care.

Results

Overall, 12 men participated in the study, of whom 9 (75%) were security guards, and the rest held management positions. The motivators for linkage to care coalesced under five categories. (i) Communication (open communication, phone reminders, consistent communication) (ii) Navigating health facility systems and processes (enabling health facility environment, easy access to health care, employing ART clinic counselors as part of the study team, health workers) (iii) Linkage support (linkage companions, referral forms, linkage facilitation, individualized linkage plan, pre-arranged clinic appointments) (iv) Psychosocial support (counseling sessions, family support, online and social media support, peer support) (v) workplace environment (employer's support, work schedules and policies). The barriers to linkage to HIV care included (i) Inflexible work schedules, (ii) Far distances to travel to access ART (iii) mandatory work transfers, (iv) disruptive effects of the COVID-19 pandemic, (v) Denial of HIV-positive results and (vi) fear of stigma and discrimination at health facilities.

Conclusion

The findings suggest the need for innovative interventions to facilitate regular follow-up and open communication with workplace-based HIV self-testers, to improve linkage to HIV care and treatment. Furthermore, initiating linkage plans during pre-test counseling and working in collaboration with health facilities and clinics may improve linkage to care.

Delivering an mHealth Adherence Support Intervention for Patients With HIV: Mixed Methods Process Evaluation of the Philippines Connect for Life Study

Background

The Philippines HIV epidemic is one of the fastest growing epidemics globally, and infections among men who have sex with men are increasing at an alarming rate. Connect for Life Philippines is a mobile health (mHealth) intervention that supports antiretroviral therapy (ART) adherence in this key population through individualized voice calls and SMS text messages.

Objective

The objective of this process evaluation is to assess the intervention reach, dose delivered and received, fidelity, and acceptability and to describe contextual factors affecting the implementation of an mHealth adherence support intervention for patients on ART in a clinic in Metro Manila, Philippines.

Methods

A mixed methods process evaluation approach was used in an observational cohort study. Quantitative data sources for the process evaluation were call and SMS text message logs obtained from the mHealth platform and questionnaires collected at 12-, 24-, and 48-week study visits. Qualitative data were collected from process reports and through a series of focus group discussions conducted with a subset of participants during the intervention development phase, after an initial 8-week pilot phase, and at the end of the study.

Results

The 462 study participants received 31,095 interactive voice calls and 8234 SMS text messages during the study. Owing to technical issues, intervention fidelity was low, with only 22.1% (102/462) of the participants receiving reminders via voice calls and others (360/462, 77.9%) receiving only SMS text messages during the intervention. After 48 weeks in the study, 63.5% (293/462) of the participants reported that they would be quite likely or very likely to recommend the program to a friend, and 53.8% (249/462) of the participants reported that they benefited quite a bit or very much from the intervention. Participants who were on ART for <6 months at the beginning of the study and those who received the daily or weekly pill reminders were more likely to report that they benefited from the intervention (P=.02 and P=.01, respectively).

Conclusions

The Connect for Life intervention had high participant satisfaction and acceptability, especially among those who received high dose of the intervention. However, poor reliability of local telecommunication networks had a large impact on the intervention’s usability, fidelity, and dose received.

Strategies to improve HIV care outcomes for people with HIV who are out of care

OBJECTIVE

The aim of this study was to evaluate the effectiveness of five intervention strategies: patient navigation, appointment help/alerts, psychosocial support, transportation/appointment accompaniment, and data-to-care on HIV care outcomes among persons with HIV (PWH) who are out of care (OOC).

DESIGN

A systematic review with meta-analysis.

METHODS

We searched CDC's Prevention Research Synthesis (PRS) Project's cumulative HIV database to identify intervention studies conducted in the U.S., published between 2000 and 2020 that included comparisons between groups or prepost, and reported at least one relevant outcome (i.e. re-engagement or retention in HIV care, and viral suppression). Effect sizes were meta-analyzed using random-effect models to assess intervention effectiveness.

RESULTS

Thirty-nine studies reporting on 42 unique interventions met the inclusion criteria. Overall, intervention strategies are effective in improving re-engagement in care [odds ratio (OR) = 1.79;95% confidence interval (95% CI): 1.36-2.36, k = 14], retention in care (OR = 2.01; 95% CI: 1.64-2.64, k = 22), and viral suppression (OR = 2.50;95% CI: 1.87-3.34, k = 27). Patient navigation, appointment help/alerts, psychosocial support, and transportation/appointment accompaniment improved all three HIV care outcomes. Data-to-care improved re-engagement and retention but had insufficient evidence for viral suppression.

CONCLUSION

Several strategies are effective for improving HIV care outcomes among PWH who are OOC. More work is still needed for consistent definitions of OOC and HIV care outcomes, better reporting of intervention and cost data, and identifying how best to implement and scale-up effective strategies to engage and retain OOC PWH in care and reach the ending the HIV epidemic goals.

Evaluation of the Implementation and Effectiveness of a Mobile Health Intervention to Improve Outcomes for People With HIV in the Washington, DC Cohort: Study Protocol for a Cluster Randomized Controlled Trial

BACKGROUND

Gaps remain in achieving retention in care and durable HIV viral load suppression for people with HIV in Washington, DC (hereafter DC). Although people with HIV seeking care in DC have access to a range of supportive services, innovative strategies are needed to enhance patient engagement in this setting. Mobile health (mHealth) interventions have shown promise in reaching previously underengaged groups and improving HIV-related outcomes in various settings.

OBJECTIVE

This study will evaluate the implementation and effectiveness of a clinic-deployed, multifeature mHealth intervention called PositiveLinks (PL) among people with HIV enrolled in the DC Cohort, a longitudinal cohort of people with HIV receiving care in DC. A cluster randomized controlled trial will be conducted using a hybrid effectiveness-implementation design and will compare HIV-related outcomes between clinics randomized to PL versus usual care.

METHODS

The study aims are threefold: (1) We will perform a formative evaluation of PL in the context of DC Cohort clinics to test the feasibility, acceptability, and usability of PL and tailor the platform for use in this context. (2) We will conduct a cluster randomized controlled trial with 12 DC Cohort clinics randomized to PL or usual care (n=6 [50%] per arm) and measure the effectiveness of PL by the primary outcomes of patient visit constancy, retention in care, and HIV viral load suppression. We aim to enroll a total of 482 participants from DC Cohort clinic sites, specifically including people with HIV who show evidence of inconsistent retention in care or lack of viral suppression. (3) We will use the Consolidated Framework for Implementation Research (CFIR) and the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework to measure implementation success and identify site, patient, provider, and system factors associated with successful implementation. Evaluation activities will occur pre-, mid-, and postimplementation.

RESULTS

Formative data collection was completed between April 2021 and January 2022. Preliminary mHealth platform modifications have been performed, and the first round of user testing has been completed. A preimplementation evaluation was performed to identify relevant implementation outcomes and design a suite of instruments to guide data collection for evaluation of PL implementation throughout the trial period. Instruments include those already developed to support DC Cohort Study activities and PL implementation in other cohorts, which required modification for use in the study, as well as novel instruments designed to complete data collection, as guided by the CFIR and RE-AIM frameworks.

CONCLUSIONS

Formative and preimplementation evaluations will be completed in spring 2022 when the trial is planned to launch. Specifically, comprehensive formative data analysis will be completed following data collection, coding, preliminary review, and synthesis. Corresponding platform modifications are ready for beta testing within the DC Cohort. Finalization of the platform for use in the trial will follow beta testing.

Point-of-care viral load testing among adolescents and young adults living with HIV in Haiti: a randomized control trial

HIV viral load (VL) monitoring can reinforce antiretroviral therapy (ART) adherence. Standard VL testing requires high laboratory capacity and coordination between clinic and laboratory which can delay results. A randomized trial comparing point-of-care (POC) VL testing to standard VL testing among 150 adolescents and young adults, ages 10-24 years, living with HIV in Haiti determined if POC VL testing could return faster results and improve ART adherence and viral suppression. Participants received a POC VL test with same-day result (POC arm) or a standard VL test with result given 1 month later (SOC arm). POC arm participants were more likely to receive a test result within 6 weeks than SOC arm participants (94.7% vs. 80.1%; p1000 copies/ml and low self-reported ART adherence was stronger in the POC arm (OR: 6.57; 95%CI: 2.12-25.21) than the SOC arm (OR: 2.62; 95%CI: 0.97-7.44) suggesting more accurate self-report in the POC arm. POC VL testing was effectively implemented in this low-resource setting with faster results and is a pragmatic intervention that may enable clinicians to identify those with high VL to provide enhanced counseling or regimen changes sooner.Trial registration: ClinicalTrials.gov identifier: NCT03288246.

Process evaluation for the adaptation, testing and dissemination of a mobile health platform to support people with HIV and tuberculosis in Irkutsk, Siberia

OBJECTIVES

We developed and tested a mobile health-based programme to enhance integration of HIV and tuberculosis (TB) care and to promote a patient-centred approach in a region of high coinfection burden. Phases of programme development included planning, stakeholder interviews and platform re-build, testing and iteration.

SETTING

In Irkutsk, Siberia, HIV/TB coinfection prevalence is high relative to the rest of the Russian Federation.

PARTICIPANTS

Pilot testing occurred for a cohort of 60 people with HIV and TB.

RESULTS

Key steps emerged to ensure the mobile health-based programme could be operational and adequately adapted for the context, including platform language adaptation, optimisation of server management, iteration of platform features, and organisational practice integration. Pilot testing of the platform rebuild yielded favourable patient perceptions of usability and acceptability at 6 months (n=47 surveyed), with 18 of 20 items showing scores above 4 (on a scale from 1 to 5) on average. Development of this mobile health-based programme for integrated care of infections highlighted the importance of several considerations for tailoring these interventions contextually, including language adaptation and technological capacity, but also, importantly, contextualised patient preferences related to privacy and communication with peers and/or providers, existing regional capacity for care coordination of different comorbidities, and infection severity and treatment requirements.

CONCLUSIONS

Our experience demonstrated that integration of care for TB and HIV can be well served by using multimodal mobile health-based programmes, which can enhance communication and streamline workflow between providers across multiple collaborating institutions and improve continuity between inpatient and outpatient care settings. Further study of programme impact on contextual disease-related stigma and social isolation as well as evaluation of implementation on a broader scale for HIV care is currently under way.

Six-month outcomes of the HOPE smartphone application designed to support treatment with medications for opioid use disorder and piloted during an early statewide COVID-19 lockdown

Background

Morbidity and mortality related to opioid use disorder (OUD) in the U.S. is at an all-time high. Innovative approaches are needed to address gaps in retention in treatment with medications for opioid use disorder (MOUD). Mobile health (mHealth) approaches have shown improvement in engagement in care and associated clinical outcomes for a variety of chronic diseases, but mHealth tools designed specifically to support patients treated with MOUD are limited.

Methods

Following user-centered development and testing phases, a multi-feature smartphone application called HOPE (Heal. Overcome. Persist. Endure) was piloted in a small cohort of patients receiving MOUD and at high risk of disengagement in care at an office-based opioid treatment (OBOT) clinic in Central Virginia. Outcomes were tracked over a six-month period following patient enrollment. They included retention in care at the OBOT clinic, usage of various features of the application, and self-rated measures of mental health, substance use, treatment and recovery.

Results

Of the 25 participants in the HOPE pilot study, a majority were retained in care at 6 months (56%). Uptake of bi-directional features including messaging with providers and daily check-ins of mood, stress and medication adherence peaked at one month, and usage persisted through the sixth month. Patients who reported that distance to clinic was a problem at baseline had higher loss to follow up compared to those without distance as a reported barrier (67% vs 23%, p = 0.03). Patients lost to in-person clinic follow up continued to engage with one or more app features, indicating that mHealth approaches may bridge barriers to clinic visit attendance. Participants surveyed at baseline and 6 months (N = 16) scored higher on scales related to overall self-control and self-efficacy related to drug abstinence.

Conclusions

A pilot study of a novel multi-feature smartphone application to support OUD treatment showed acceptable retention in care and patient usage at 6 months. Further study within a larger population is needed to characterize ‘real world’ uptake and association with outcomes related to retention in care, relapse prevention, and opioid-associated mortality.

Adapting digital health interventions for the evolving HIV landscape: examples to support prevention and treatment research

PURPOSE OF REVIEW

Although many HIV prevention and/or treatment digital health interventions (DHIs) have shown feasibility and acceptability, fewer have indicated efficacy, and only a subset have been adapted for new contexts. Adaptation is a key element of pragmatic implementation science research. Adaptation is cost effective and time efficient compared with new development. Leveraging adaptation can lead to accelerated scale-up and enhanced public health impact. Considering the value of adaptation, the purpose of this piece is to present examples of DHI to DHI adaptation sequences to inform future HIV prevention and/or treatment research.

RECENT FINDINGS

From an examination of recent academic articles (01 November 2016 to 31 October 2021), we identified adaptation sequences that included an original DHI with at least two adaptations. Four models are presented herein; examples consist of adapted DHIs for new population, health outcome, geography, or a combination thereof.

SUMMARY

Adaptation is a promising scientific approach to expeditiously respond to the evolving HIV landscape. We present examples of DHI adaptations alongside considerations for each type of adaptation; we also present adaptation challenges with responsive strategies. We suggest when conducted with attention to rigor (leveraging adaptation frameworks, community engagement, and tailoring content), adaptation is a powerful tool to pragmatically address the HIV epidemic.

Pilot Randomized Controlled Trial of Motivational Interviewing with Sexual Minority Male Couples to Reduce Drug Use and Sexual Risk: The Couples Health Project

A randomized controlled trial evaluated the preliminary efficacy of a dyadically-delivered motivational interviewing (MI) intervention to reduce drug use and sexual risk in a sample of 50 sexual minority (cis)male (SMM) couples. In each couple, at least one partner was aged 18-29; reported drug use and sexual HIV transmission risk; and was HIV-negative. Couples were randomized to either the three-session MI intervention or an attention-matched control, with follow-up surveys completed at 3- and 6-months post-baseline. Between-group differences for all outcomes were non-significant in the overall sample. Subsequent moderation analyses indicated the intervention significantly reduced illicit drug use (excluding marijuana) at 3-month follow-up when either respondents (B = - 1.96; interval rate ratio-IRR 0.02-1.22; p = .001), their partners (B = - 2.60; IRR 0.01-0.64; p = .004), or both (B = - 2.38; IRR 0.01-0.80; p = .001) reported high levels of baseline use. The intervention also reduced condomless anal sex (CAS) with casual partners when both partners reported high frequency baseline CAS (B = - 2.54; IRR 0.01-0.83; p = .047). Findings provide initial evidence of the potential for MI to address drug use and sexual risk-taking among SMM couples at highest risk.Trial Registration ClinicalTrials.gov (NIH U.S. National Library of Medicine) Identifier: #NCT03386110.

Challenges in Participant Engagement and Retention using Mobile Health Apps: A Literature Review (Preprint)

Background

Mobile health (mHealth) apps are revolutionizing the way clinicians and researchers monitor and manage the health of their participants. However, many studies using mHealth apps are hampered by substantial participant dropout or attrition, which may impact the representativeness of the sample and the effectiveness of the study. Therefore, it is imperative for researchers to understand what makes participants stay with mHealth apps or studies using mHealth apps.

Objective

This study aimed to review the current peer-reviewed research literature to identify the notable factors and strategies used in adult participant engagement and retention.

Methods

We conducted a systematic search of PubMed, MEDLINE, and PsycINFO databases for mHealth studies that evaluated and assessed issues or strategies to improve the engagement and retention of adults from 2015 to 2020. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Notable themes were identified and narratively compared among different studies. A binomial regression model was generated to examine the factors affecting retention.

Results

Of the 389 identified studies, 62 (15.9%) were included in this review. Overall, most studies were partially successful in maintaining participant engagement. Factors related to particular elements of the app (eg, feedback, appropriate reminders, and in-app support from peers or coaches) and research strategies (eg, compensation and niche samples) that promote retention were identified. Factors that obstructed retention were also identified (eg, lack of support features, technical difficulties, and usefulness of the app). The regression model results showed that a participant is more likely to drop out than to be retained.

Conclusions

Retaining participants is an omnipresent challenge in mHealth studies. The insights from this review can help inform future studies about the factors and strategies to improve participant retention.

A Preliminary Test of an mHealth Facilitated Health Coaching Intervention to Improve Medication Adherence among Persons Living with HIV

This study examined feasibility, acceptability, and preliminary efficacy of an mHealth facilitated health coaching antiretroviral therapy (ART) adherence intervention. Persons living with HIV (n = 53) were randomized to an in-person adherence session and 12 months of app access and health coaching via the app (Fitbit Plus) versus single adherence session (SOC). At baseline and 1, 3, 6, and 12 months, we measured ART adherence, substance use, and depressive symptoms. We also conducted individual qualitative interviews. The intervention was found to be largely feasible and highly acceptable, with the health coach spending an average of 2.4 min per month with a participant and 76.5% of Fitbit Plus participants using the app regularly at 12 months. While most comparisons were not significant, the pattern of results was consistent with better adherence in the Fitbit Plus compared to SOC condition. Substance use was significantly associated with poorer ART adherence while depressive symptoms were not.ClinicalTrials.gov Identifier: NCT02676128; Registered: 2/8/2016.

What Works Best to Engage Participants in Mobile App Interventions and e-Health: A Scoping Review

Background:

Despite the growing popularity of mobile app interventions, specific engagement components of mobile apps have not been well studied.

Methods:

The objectives of this scoping review are to determine which components of mobile health intervention apps encouraged or hindered engagement, and examine how studies measured engagement.

Results:

A PubMed search on March 5, 2020 yielded 239 articles that featured the terms engagement, mobile app/mobile health, and adult. After applying exclusion criteria, only 54 studies were included in the final analysis.

Discussion:

Common app components associated with increased engagement included: personalized content/feedback, data visualization, reminders/push notifications, educational information/material, logging/self-monitoring functions, and goal-setting features. On the other hand, social media integration, social forums, poor app navigation, and technical difficulties appeared to contribute to lower engagement rates or decreased usage. Notably, the review revealed a great variability in how engagement with mobile health apps is measured due to lack of established processes.

Conclusion:

There is a critical need for controlled studies to provide guidelines and standards to help facilitate engagement and its measurement in research and clinical trial work using mobile health intervention apps.

A Review of Interventions to Enhance HIV Medication Adherence

PURPOSE OF REVIEW

Adherence to antiretroviral treatment (ART) is crucial for the successful treatment of HIV. Unfortunately, it is estimated that 45% of persons living with HIV (PLWH) have poor adherence to ART. To provide health care professionals and PLWH with effective tools for supporting adherence, researchers have investigated the effectiveness of psychosocial interventions to enhance adherence to ART. In this paper, interventional studies, systematic reviews, and meta-analyses that examine ART adherence interventions for PLWH are reviewed.

RECENT FINDINGS

There is great variability among interventions in terms of quality, sample, measures, and outcome characteristics. Despite a diverse and wide-ranging assortment of ART adherence interventions, consistent lessons have been learned. Interventions that focus on individual and interpersonal factors have been effective for improving ART adherence; however, the improvement in adherence tends to be short-lived. Additionally, interventions are most successful when tailored to those at risk for poor adherence. Finally, theory-based interventions are more likely to be effective than non-theory-based interventions. A variety of individual-level psychological interventions have been shown to be effective in improving ART adherence in the short term. Digital and mobile interventions have the potential to improve dissemination and implementation of these evidence-based interventions and could be used to extend intervention effects. Future interventions that address issues of accessibility, inequality, structural and institutional barriers to ART adherence should also be tested and prioritized. Implementation science frameworks can be used to assess and address issues of accessibility and systematic barriers to care.

Acceptability and feasibility of a mobile health application for blood pressure monitoring in rural Uganda

Background

Mobile technologies to improve blood pressure control in resource-limited settings are needed. We adapted and evaluated the acceptability and feasibility of PositiveLinks, a mobile phone application for self-monitoring, social support, and engagement in care for people living with HIV, among patients with hypertension in rural Uganda.

Methods

We enrolled adults on treatment for hypertension at Mbarara Regional Referral Hospital and Mbarara Municipal health center IV, southwestern Uganda. We provided and educated all participants on the use of PositiveLinks application and automated blood pressure monitors. We administered a baseline questionnaire and performed in-depth interviews 30 days later to explore acceptability, feasibility, medication adherence, social support, and blood pressure control.

Results

A total of 37 participants completed the interviews, mean age of 58 years (SD 10.8) and 28 (75.7%) were female. All participants embraced the PositiveLinks mobile app and were enthusiastic about self-monitoring of blood pressure, 35 (94.6%) experienced peer to peer support. Among the 35 participants non-adherent to medications at baseline, 31 had improved medication adherence. All except 1 of the 31(83.8%) who had uncontrolled blood pressure at baseline, had self-reported controlled blood pressure after 30 days of use of PositiveLinks.

Conclusion

Patients with hypertension in rural Uganda embraced the PositiveLinks mobile application and had improved medication adherence, social support, and blood pressure control. Further assessment of cost-effectiveness of the application in blood pressure control in resource-limited settings will be pursued in future studies.

Toward understanding the impact of mHealth features for people with HIV: a latent class analysis of PositiveLinks usage

PositiveLinks (PL) is a multi-feature smartphone-based platform to improve engagement-in-care and viral suppression (VS) among clinic patients living with HIV. Features include medication reminders, mood/stress check-ins, a community board, and secure provider messaging. Our goal was to examine how PL users interact with the app and determine whether usage patterns correlate with clinical outcomes. Patients (N = 83) at a university-based Ryan White clinic enrolled in PL from June 2016 to March 2017 and were followed for up to 12 months. A subset (N = 49) completed interviews after 3 weeks of enrollment to explore their experiences with and opinions of PL. We differentiated PL members based on 6-month usage of app features using latent class analysis. We explored characteristics associated with class membership, compared reported needs and preferences by class, and examined association between class and VS. The sample of 83 PL members fell into four classes. "Maximizers" used all app features frequently (27%); "Check-in Users" tended to interact only with daily queries (22%); "Moderate All-Feature Users" used all features occasionally (33%); and "As-Needed Communicators" interacted with the app minimally (19%). VS improved or remained high among all classes after 6 months. VS remained high at 12 months among Maximizers (baseline and 12-month VS: 100%, 94%), Check-in Users (82%, 100%), and Moderate All-Feature Users (73%, 94%) but not among As-Needed Communicators (69%, 60%). This mixed-methods study identified four classes based on PL usage patterns that were distinct in characteristics and clinical outcomes. Identifying and characterizing mHealth user classes offers opportunities to tailor interventions appropriately based on patient needs and preferences as well as to provide targeted alternative support to achieve clinical goals.

Pills, PrEP, and Pals: Adherence, Stigma, Resilience, Faith and the Need to Connect Among Minority Women With HIV/AIDS in a US HIV Epicenter

Background: Ending HIV/AIDS in the United States requires tailored interventions. This study is part of a larger investigation to design mCARES, a mobile technology-based, adherence intervention for ethnic minority women with HIV (MWH).

Objective: To understand barriers and facilitators of care adherence (treatment and appointment) for ethnic MWH; examine the relationship between these factors across three ethnic groups; and, explore the role of mobile technologies in care adherence.

Methods: Cross-sectional, mixed-methods data were collected from a cohort of African-American, Hispanic-American and Haitian-American participants. Qualitative data were collected through a focus group (n = 8) to assess barriers and facilitators to care adherence. Quantitative data (n = 48) surveyed women on depressive symptomology (PHQ-9), HIV-related stigma (HSS) and resiliency (CD-RISC25). We examined the relationships between these factors and adherence to treatment and care and across groups.

Findings: Qualitative analyses revealed that barriers to treatment and appointment adherence were caregiver-related stressors (25%) and structural issues (25%); routinization (30%) and religion/spirituality (30%) promoted adherence to treatment and care. Caregiver role was both a hindrance (25%) and promoter (20%) of adherence to treatment and appointments. Quantitatively, HIV-related stigma differed by ethnic group; Haitian-Americans endorsed the highest levels while African-Americans endorsed the lowest. Depression correlated to stigma (R = 0.534; p < 0.001) and resiliency (R = −0.486; p < 0.001). Across ethnic groups, higher depressive symptomology and stigma were related to viral non-suppression (p < 0.05)—a treatment adherence marker; higher resiliency was related to viral suppression. Among Hispanic-Americans, viral non-suppression was related to depression (p < 0.05), and among African-Americans, viral suppression was related to increased resiliency (p < 0.04).

Conclusion: Multiple interrelated barriers to adherence were identified. These findings on ethnic group-specific differences underscore the importance of implementing culturally-competent interventions. While privacy and confidentiality were of concern, participants suggested additional intervention features and endorsed the use of mCARES as a strategy to improve adherence to treatment and appointments.

Measuring Unmet Needs among Persons Living with HIV at Different Stages of the Care Continuum

Unmet needs can impede optimal care engagement, impacting the health and well-being of people living with HIV (PLWH); yet, whether unmet needs differ by care engagement status is not well understood. Using surveys and qualitative interviews, we examined and compared unmet needs for PLWH (n = 172) at different levels of care engagement. Unmet needs varied only slightly by care status. Survey findings revealed that provision of housing, emergency financial assistance, employment assistance, and food security were the greatest unmet need; for those in care, housing was the greatest unmet need, whereas for those sporadically in care or out of care, employment assistance was the greatest unmet needs. Qualitative interviews likewise illustrated that a lack of financial resources including insurance, housing, employment, and transportation presented barriers to care engagement across all care groups. Our findings indicate that unmet needs among PLWH are complex and multi-faceted across care engagement status.

A Review of Recent HIV Prevention Interventions and Future Considerations for Nursing Science

ABSTRACT

As our knowledge of HIV evolved over the decades, so have the approaches taken to prevent its transmission. Public health scholars and practitioners have engaged in four key strategies for HIV prevention: behavioral-, technological-, biomedical-, and structural/community-level interventions. We reviewed recent literature in these areas to provide an overview of current advances in HIV prevention science in the United States. Building on classical approaches, current HIV prevention models leverage intimate partners, families, social media, emerging technologies, medication therapy, and policy modifications to effect change. Although much progress has been made, additional work is needed to achieve the national goal of ending the HIV epidemic by 2030. Nurses are in a prime position to advance HIV prevention science in partnership with transdisciplinary experts from other fields (e.g., psychology, informatics, and social work). Future considerations for nursing science include leveraging transdisciplinary collaborations and consider social and structural challenges for individual-level interventions.

An Implementation Strategy to Expand Mobile Health Use in HIV Care Settings: Rapid Evaluation Study Using the Consolidated Framework for Implementation Research

Background

Mobile health (mHealth) apps can provide support to people living with a chronic disease by offering resources for communication, self-management, and social support. PositiveLinks (PL) is a clinic-deployed mHealth app designed to improve the health of people with HIV. In a pilot study, PL users experienced considerable improvements in care engagement and viral load suppression. To promote its expansion to other HIV clinics, we developed an implementation strategy consisting of training resources and on-demand program support.

Objective

The objective of our study was to conduct an interim analysis of the barriers and facilitators to PL implementation at early adopting sites to guide optimization of our implementation strategy.

Methods

Semistructured interviews with stakeholders at PL expansion sites were conducted. Analysis of interviews identified facilitators and barriers that were mapped to 22 constructs of the Consolidated Framework for Implementation Research (CFIR). The purpose of the analysis was to identify the facilitators and barriers to PL implementation in order to adapt the PL implementation strategy. Four Ryan White HIV clinics were included. Interviews were conducted with one health care provider, two clinic managers, and five individuals who coordinated site PL activities.

Results

Ten common facilitators and eight common barriers were identified. Facilitators to PL implementation included PL’s fit with patient and clinic needs, PL training resources, and sites’ early engagement with their information technology personnel. Most barriers were specific to mHealth, including access to Wi-Fi networks, maintaining patient smartphone access, patient privacy concerns, and lack of clarity on how to obtain approvals for mHealth use.

Conclusions

The CFIR is a useful framework for evaluating mHealth interventions. Although PL training resources were viewed favorably, we identified important barriers to PL implementation in a sample of Ryan White clinics. This enabled our team to expand guidance on identifying information technology stakeholders and procuring and managing mobile resources. Ongoing evaluation results continue to inform improvements to the PL implementation strategy, facilitating PL access for future expansion sites.
