Effectiveness of mobile phone text message reminder interventions to improve adherence to antiretroviral therapy among adolescents living with HIV: A systematic review and meta-analysis

Mobile mental health application use, and app feature preferences among individuals with mental disorders in Ethiopia: A cross-sectional survey

BACKGROUND

Mobile health applications have been shown to assist in the treatment of mental illnesses, yet their potential remains underutilized. As supportive care, mental health applications use may be useful tools in improving mental health literacy and treatment outcomes, but patients' use of and interest in using these apps have not been studied in low-income countries like Ethiopia. This study explores the determinants of patients' mental health app use interests and app feature preferences.

METHODS

A cross-sectional study was conducted with 419 outpatient individuals with mental health disorders at Amanuel Mental Specialized Hospital, Ethiopia, between October and November 2023, using a convenience sampling method. Patients' self-reported mental health app use, interests, attitudes, and app feature preferences were collected. A multivariate logistic regression model was used to identify the associated factors.

RESULTS

Overall prevalence of not interested, somewhat interested, interested, and extremely interested in mental health app use was 5.3 %, 16.9 %, 27.7 %, and 50.1 % respectively. The proportion of current mental health apps use was low (21.2 %). Current mental health app use is associated with living in an urban area (AOR = 6.69, CI: 3.19-14) and having a higher education level (4.12 (2.02-8.04). Furthermore, app features such as psychoeducation, symptom tracking, and self-management techniques ranked as the most preferred app features.

CONCLUSIONS

Most study participants were interested in using mental health apps, but only about one in four were using mental health apps. This suggests promise for their utility in the Ethiopian context. App developers and policymakers should consider rural residents', lower educational levels, and patient app preferences when developing these applications.

The effect of proactive, interactive, two-way texting on 12-month retention in antiretroviral therapy: Findings from a quasi-experimental study in Lilongwe, Malawi

BACKGROUND

Retaining clients on antiretroviral therapy (ART) is challenging, especially during the first year on ART. Mobile health (mHealth) interventions show promise to close retention gaps. We aimed to assess reach (who received the intervention?) and effectiveness (did it work?) of a hybrid two-way texting (2wT) intervention to improve ART retention at a large public clinic in Lilongwe, Malawi.

METHODS

Between August 2021-June 2023, in a quasi-experimental study, outcomes were compared between two cohorts of new ART clients: 1) those opting into 2wT who received automated, weekly motivation short messaging service (SMS) messages and response-requested appointment reminders; and 2) a matched historical cohort receiving standard of care (SoC). Reach was defined as "the proportion clients ≤6 months of ART initiation eligible for 2wT". 2wT effectiveness was assessed in time-to-event analysis. Retention was presented in a Kaplan-Meier plot and compared between 2wT and SoC using a log-rank test. The effect of 2wT on ART dropout (lost to follow-up or stopped ART) was estimated using Fine-Gray competing risk regression models, adjusting for sex, age and WHO HIV stage at ART initiation.

RESULTS

Of 1,146 clients screened, 501 were eligible for 2wT, a reach of 44%. Lack of phone (393/645; 61%) and illiteracy (149/645; 23%) were the most common ineligibility reasons. Among 468 participants exposed to 2wT, 12-month probability of ART retention was 91% (95% CI: 88% - 94%) compared to 76% (95% CI: 72% - 80%) among 468 SoC participants (p<0.001). Compared to SoC, 2wT participants had a 65% lower hazard of ART dropout at any timepoint (sub-distribution hazard ratio 0.35, 95% CI: 0.24-0.51; p<0.001).

CONCLUSIONS

2wT did not reach all clients. For those who opted-in, 2wT significantly increased 12-month ART retention. Expansion of 2wT as a complement to other retention interventions should be considered in other low-resource, routine ART settings.

Long-acting injectable antiretroviral treatment: experiences of people with HIV and their healthcare providers in Uganda

INTRODUCTION

Long-acting injectable antiretroviral treatment (LAI-ART) has emerged as a novel alternative to the burden of daily oral pills. The bi-monthly intramuscular injectable containing cabotegravir and rilpivirine holds the promise of improving adherence to ART. The perspectives of potential users of LAI-ART, the majority of whom reside in Eastern and Southern Africa, are still largely unexplored. We set out to understand the experiences of people with HIV (PWH) who received LAI-ART at Fort Portal Regional Referral Hospital in mid-Western Uganda for at least 12 months.

METHODS

This qualitative study, conducted between July and August 2023, was nested within a larger study. We conducted four focus groups with 32 (out of 69) PWH who received intramuscular injections of cabotegravir and rilpivirine. In-depth interviews were held with six health workers who delivered LAI-ART to PWH. Data were analyzed by thematic approach broadly modeled on the five domains of the Consolidated Framework for Implementation Research (CFIR).

RESULTS

There was high acceptability of LAI-ART (30 /32 or 94%) participants requested to remain on LAI-ART even after the end of the 12-month trial. Adherence to ART was reportedly improved when compared to daily oral treatment. Participants credited LAI-ART with; superior viral load suppression, redemption from the daily psychological reminder of living with HIV, enhanced privacy in HIV care and treatment, reduced HIV-related stigma associated with taking oral pills and that it absolved them from carrying bulky medication packages. Conversely, nine participants reported pain around the injection site and a transient fever soon after administering the injection as side effects of LAI-ART. Missed appointments for receiving the bi-monthly injection were common. Providers identified health system barriers to the prospective scale-up of LAI-ART which include the perceived high cost of LAI-ART, stringent cold chain requirements, physical space limitations, and workforce skills gaps in LAI-ART delivery as potential drawbacks.

CONCLUSION

Overall, PWH strongly preferred LAI-ART and expressed a comparatively higher satisfaction with this treatment alternative. Health system barriers to potential scale-up are essential to consider if a broader population of PWH will benefit from this novel HIV treatment option in Uganda and other resource-limited settings.

Deceptively Simple yet Profoundly Impactful: Text Messaging Interventions to Support Health

This paper examines the use of text message (SMS) interventions for health-related behavioral support. It first outlines the historical progress in SMS intervention research publications and the variety of funds from US government agencies. A narrative review follows, highlighting the effectiveness of SMS interventions in key health areas, such as physical activity, diet and weight loss, mental health, and substance use, based on published meta-analyses. It then outlines advantages of text messaging compared to other digital modalities, including the real-time capability to collect information and deliver microdoses of intervention support. Crucial design elements are proposed to optimize effectiveness and longitudinal engagement across communication strategies, psychological foundations, and behavior change tactics. We then discuss advanced functionalities, such as the potential for generative artificial intelligence to improve user interaction. Finally, major challenges to implementation are highlighted, including the absence of a dedicated commercial platform, privacy and security concerns with SMS technology, difficulties integrating SMS interventions with medical informatics systems, and concerns about user engagement. Proposed solutions aim to facilitate the broader application and effectiveness of SMS interventions. Our hope is that these insights can assist researchers and practitioners in using SMS interventions to improve health outcomes and reducing disparities.

Factors associated with willingness to use mHealth interventions for medication adherence among people living with HIV attending a tertiary hospital in sub-Saharan Africa

INTRODUCTION

There is increasing evidence in favor of enhancing adherence to antiretroviral therapy (ART) in people living with HIV (PLHIV) through mobile health (mHealth) assessment and intervention. The study aims to establish the willingness to adopt mobile phone technology to enhance adherence to ART among PLHIV.

METHODS

The Researchers adopted a cross-sectional survey. Systematic sampling was employed in selecting 237 PLHIV in the HIV clinic for adults at Ido-Ekiti's Federal Teaching Hospital, Nigeria. Data collection was via a 33-item semi-structured questionnaire administered by the interviewer. Information collected via the questionnaire included details on ownership of mobile phone technology, its usage, and willingness to use it to improve adherence to HIV medication. Descriptive statistics coupled with multivariate regression was employed in analyzing data, with the level of significance at 5%.

RESULTS

The respondent's had a mean ±SD age of 46.6 ±10 years. Most of the participants were female (77.6%), and have been on ART for over 2years (88.2%). The vast majority of study participants 233 (98.3%) owned a mobile phone. 168 (70.9%) of them were willing to embrace mHealth interventions on medication adherence. Some of the factors influencing the respondent's willingness to receive the intervention were older age (OR = 0.05, 95%Cl:[0.01-0.24]), having formal education (OR = 7.12, 95%Cl:[3.01-16.53]), being diagnosed over 10years ago (OR = 15.63, 95%Cl:[3.02-80.83]) and previous use of phone to send text messages, record video, access the internet, send email and search the internet for health-related information (OR = 2.2, 95%Cl:[1.2-3.9]; OR = 1.8, 95%Cl:[1.0-3.2]; OR = 2.5, 95%Cl:[1.4-4.7]; OR = 2.7, 95%Cl:[1.2-5.5] and OR = 2.0, 95%Cl:[1.0-3.8]) respectively.

CONCLUSION

Many of the PLHIV had a cellphone and expressed willingness on their part to use it in receiving reminders to take their medication. Older age, formal education and internet users were significantly more willing to get reminders to take their medication.

Intervention fidelity and factors affecting the process of implementing a mobile phone text messaging intervention among adolescents living with HIV: a convergent mixed-methods study in southern Ethiopia

OBJECTIVE

To assess the intervention fidelity and explore contextual factors affecting the process of implementing a mobile phone text messaging intervention in improving adherence to and retention in care among adolescents living with HIV, their families and their healthcare providers in southern Ethiopia.

DESIGN

A convergent mixed-methods design guided by the process evaluation theoretical framework and the Reach, Effectiveness, Adoption, Implementation and Maintenance framework was used alongside a randomised controlled trial to examine the fidelity and explore the experiences of participants in the intervention.

SETTING

Six hospitals and five health centres provide HIV treatment and care to adolescents in five zones in southern Ethiopia.

PARTICIPANTS

Adolescents (aged 10-19), their families and their healthcare providers.

INTERVENTION

Mobile phone text messages daily for 6 months or standard care (control).

RESULTS

153 participants were enrolled in the process evaluation. Among the 153 enrolled in the intervention arm, 78 (49.02%) were male and 75 (43.8%) were female, respectively. The mean and SD age of the participants is 15 (0.21). The overall experiences of implementing the text messages reminder intervention were described as helpful in terms of treatment support for adherence but had room for improvement. During the study, 30 700 text messages were sent, and fidelity was high, with 99.4% successfully delivered text messages during the intervention. Barriers such as failed text messages delivery, limitations in phone ownership and technical limitations affected fidelity. Technical challenges can hinder maintenance, but a belief in the future of digital communication permeates the experiences of the text message reminders.

CONCLUSIONS

Overall fidelity was high, and participants' overall experiences of mobile phone text messages were expressed as helpful. Contextual factors, such as local telecommunications networks and local electric power, as well as technical and individual factors must be considered when planning future interventions.

Experiences of support by unsuppressed adolescents living with HIV and their caregivers in Windhoek, Namibia: a qualitative study

Background

Adolescents living with HIV (ALHIV) lag behind younger children and adults in the achievement of HIV care and treatment targets for HIV epidemic control. Treatment outcomes for adolescents may be influenced by their experiences with the support provided in HIV programs. We report on the experiences of virally unsuppressed adolescents and their caregivers with the current support in primary healthcare settings in Namibia.

Methods

A qualitative descriptive and exploratory study was conducted in 13 public primary healthcare facilities in Windhoek, Namibia. A total of 25 in-depth interviews were conducted with unsuppressed adolescents (n = 14) and their caregivers (n = 11) between August and September 2023. The audio-recorded interviews were transcribed verbatim, and uploaded into ATLAS.ti software, and subjected to thematic content analysis.

Findings

Three main support domains for the unsuppressed adolescents emerged from our analysis, namely: psychosocial, clinical and care, and socioeconomic support. The psychosocial support was delivered through peer support (teen clubs and treatment supporters) and enhanced adherence counselling mostly. The clinical and care support included implementing adolescent-friendly HIV services, differentiated service delivery approaches, and caregivers and healthcare worker care support for improved ART adherence, clinic attendance and continuous engagement in care. Socioeconomic support was provided for nutritional support, transport to access clinics, and school supplies, as well as income-generating projects.

Conclusion

Psychosocial, clinical and care, and socioeconomic support are key elements in addressing the needs of adolescents challenged with achieving viral suppression. Health systems may benefit from whole-of-society and whole-of-government approaches to meet the needs of ALHIV that are beyond the scope of health service delivery such as nutritional, education and socioeconomic influences on both the health and well-being of ALHIV.

Centering healthcare workers in digital health design: Usability and acceptability of two-way texting to improve retention in antiretroviral therapy in a public HIV clinic in Lilongwe, Malawi

New initiates on antiretroviral therapy (ART) are at high risk of treatment discontinuation, putting their health at risk. In low- and middle-income countries, like Malawi, appropriate digital health applications (apps) must fit into local clinic, connectivity and resource constraints. We describe the human centered design (HCD) and development process of an open-source, hybrid, two-way texting (2wT) system to improve ART retention. We detail the critical role of diverse healthcare workers (HCWs) in the HCD process to inform app usability, create buy-in, and ensure appropriate optimization for the local context. We optimized 2wT usability and acceptability over three HCD phases: 1) informal feedback sessions with diverse 2wT stakeholders, 2) a small pilot, and 3) key informant interviews. Phase one included four sessions with diverse HCWs, including "expert ART clients", clinical, technical, supervisory, and evaluation teams to inform 2wT design. In phase 2, a small pilot with 50 participating ART clients aimed to inform implementation improvement. Phase three included interviews with ten HCWs to deepen understanding of 2wT acceptability and usability, documenting strengths and weaknesses to inform optimization. Multi-phase feedback sessions with HCWs helped refine 2wT language and message timing for both weekly and tailored client-specific visit reminders. The pilot led to improvements in educational materials to guide client responses and ease interaction with HCWs. In interviews, the HCWs appreciated the HCD co-creation process, suggested ways to increase access for low-literacy clients or those without consistent phone access, and felt integrating 2wT with other eHealth platforms would improve scalability. Inclusion of HCWs across phases of HCD design, adaption, and optimization increased 2wT usability and acceptability among HCWs in this setting. Engaging HCWs into 2wT co-ownership from inception appears successful in co-creation of an app that will meet HCW needs, and therefore, enhance support for 2wT clients to attend visits and remain in care.

The effect of proactive, interactive, two-way texting on 12-month retention in antiretroviral therapy: findings from a quasi-experimental study in Lilongwe, Malawi

Background

Retaining clients on antiretroviral therapy (ART) is challenging especially during the first year on ART. Mobile health (mHealth) interventions show promise to close retention gaps. We aimed to assess reach (who received the intervention?) and effectiveness (did it work?) of a hybrid two-way texting (2wT) intervention to improve ART retention at a large public clinic in Lilongwe, Malawi.

Methods

Between August 2021 - June 2023, a quasi-experimental study compared outcomes between two cohorts of new ART clients: 1) those opting into 2wT with combined automated, weekly motivation short messaging service (SMS) messages and response-requested appointment reminders; and 2) a matched historical cohort receiving standard of care (SoC). Reach was defined as "the proportion clients ≤6 months of ART initiation eligible for 2wT". 2wT effectiveness was assessed in time-to-event analysis comparing Kaplan-Meier plots of 6- and 12-month retention between 2wT and SoC using a log-rank test. The effect of 2wT on ART drop out was estimated using multivariable Cox proportional hazard models, adjusting for sex, age and WHO stage at ART initiation.

Results

Of the 1,146 clients screened, 645 were ineligible (56%) largely due to lack of phone access (393/645; 61%) and illiteracy (149/645; 23%): a reach of 44%. Among 468 2wT participants, the 12-month probability of ART retention was 91% (95%CI: 88% - 93%) compared to 75% (95%CI: 71% - 79%) among 468 SoC participants (p<0.0001). Compared to SoC participants, 2wT participants had a 62% lower hazard of dropping out of ART care at all time points (hazard ratio 0.38, 95% CI: 0.26-0.54; p<0.001).

Conclusions

Not all clients were reached with 2wT. For those who opted-in, 2wT reduced drop out throughout the first year on ART and significantly increased 12-month retention. The proactive 2wT approach should be expanded as a complement to other interventions in routine, low-resource settings to improve ART retention.

Phone-Delivered Intervention to Improve HIV Care for Young People Living With HIV: Trial to Inform Implementation and Utility

BACKGROUND

Phone-delivered counseling has demonstrated improved health outcomes for people living with HIV. However, counseling is hampered by a lack of guidance on the frequency and duration of intervention in relation to clinical benefits. The added benefits of bidirectional (ie, interactive) vs. unidirectional (ie, passive) text messages to augment counseling are also unknown. We conducted a clinical trial of adaptive phone counseling along with either bidirectional or unidirectional text messaging for people living with HIV.

METHODS

A community sample of 425 young people (aged 16-36 years) living with HIV in Georgia, USA, received weekly phone counseling sessions with the number of sessions determined by the participant and their counselor. Participants were subsequently randomized to either (1) weekly bidirectional text messages with their counselor or (2) weekly automated unidirectional text message reminders. Participants were followed for 16 months to assess 3 primary outcomes: antiretroviral therapy (ART) adherence, HIV care engagement, and HIV suppression.

RESULTS

Participants demonstrated improved clinical outcomes over the follow-up period, with 74% of those who were not taking ART initiating treatment, 65% of those on ART improving adherence, and 47% who had detectable viral loads at baseline attaining viral suppression. The number of sessions completed predicted improved ART adherence, greater care engagement, and HIV suppression over follow-ups. Bidirectional text messages impacted care engagement by moderating the effects of counseling sessions on HIV suppression.

CONCLUSIONS

Phone counseling augmented by bidirectional text messages has the potential to improve HIV care for young adults living with HIV.

Digital Health in Enhancing Antiretroviral Therapy Adherence: A Systematic Review and Meta-Analysis

Adherence to antiretroviral therapy (ART) is essential in determining successful treatment of human immunodeficiency virus (HIV). The adoption of digital health is suggested to improve ART adherence among people living with HIV (PLHIV). This study aimed to systematically determine the effect of digital health in enhancing ART adherence among PLHIV from published studies. The systematic search was conducted on Scopus, Web of Science (WoS), PubMed, Ovid, EBSCOHost, and Google Scholar databases up to June 2022. Studies utilized any digital health as an intervention for ART adherence enhancement and ART adherence status as study's outcome was included. Digital health refers to the use of information and communication technologies to improve health. Quality assessment and data analysis were carried out using Review Manager (RevMan) version 5.4. A random-effects model computed the pooled odds ratio between intervention and control groups. The search produced a total of 1864 articles. Eleven articles were eligible for analysis. Digital health was used as follows: six studies used short message service or text message alone, three studies used mobile applications, and two studies used combination method. Four studies showed statistically significant impacts of digital health on ART adherence, while seven studies reported insignificant results. Results showed studies conducted using combination approach of digital health produced more promising outcome in ART adherence compared to single approach. New innovative in combination ways is required to address potential benefits of digital health in promoting ART adherence among PLHIV.

Developing contents for a digital adherence tool: A formative mixed-methods study among children and adolescents living with HIV in Tanzania

Optimal adherence (>95%) to antiretroviral treatment (ART) remains a challenge among children and adolescents living with HIV (CALHIV). Digital adherence tools (DAT) with reminder cues have proven feasible among adult people living with HIV (PLHIV), with some concerns about the risk of HIV status disclosure. We aimed to assess the needs, contents and acceptability of an SMS-based DAT among CALHIV. We first conducted a survey to understand potential barriers to using DAT among CALHIV, then tested the DAT intervention among purposively selected participants. The DAT intervention included using the Wisepill device, receiving daily reminder SMS and receiving adherence reports on how they had taken medication in the past month. The content of the reminder SMS differed over time from asking if the medication was taken to a more neutral SMS like "take care". Afterwards, we conducted exit interviews, in-depth interviews, and focus-group discussions. We analysed quantitative findings descriptively and used thematic content analysis for qualitative data. We included 142 children and 142 adolescents in the survey, and 20 of each used the intervention. Eighty-five percent (121/142) of surveyed participants indicated they would like to receive reminder SMS. Most of them (97/121-80%) of children and 94/121(78%) of adolescents would prefer to receive daily reminders. Participants who used the DAT mentioned to be happy to use the device. Ninety percent of them had good experience with receiving reminders and agreed that the SMS made them take medication. However, 25% experienced network problems. Participants preferred neutral reminder SMSs that did not mention the word 'medication', but preserved confidentiality. The provided adherence reports inspired participants to improve their adherence. None of the participants experienced unwanted disclosure or stigmatisation due to DAT. However, 5% of adolescents were concerned about being monitored daily. This study showed that DAT is acceptable and provided insight of the needed SMS content for a customized DAT for CALHIV.

Interventions to Improve Adolescent HIV Care Outcomes

PURPOSE OF REVIEW

This review of recent studies evaluating interventions to improve HIV care outcomes among adolescents with HIV (AHIV) was conducted to provide a comprehensive overview of the recent evidence, highlight promising approaches, and suggest directions for future research.

RECENT FINDINGS

Our scoping review revealed 65 studies evaluating a variety of interventions and using a range of study designs at various stages of research. Effective approaches included community-based, integrated service delivery models with case management, trained community adolescent treatment supporters, and consideration of social determinants of health. Recent evidence also supports the feasibility, acceptability, and preliminary efficacy of other innovative approaches, including mental health interventions as well as technology-delivered approaches; however, more research is needed to build the evidence base for these interventions. Our review's findings suggest that interventions providing comprehensive, individualized support are essential to improving HIV care outcomes among adolescents. More research is needed to build the evidence base for such interventions and ensure effective, equitable implementation to support the global target of ending the AIDS epidemic by 2030.

Effectiveness of mHealth on Adherence to Antiretroviral Therapy in Patients Living With HIV: Meta-analysis of Randomized Controlled Trials

BACKGROUND

The World Health Organization recommends that all adults with HIV adhere to antiretroviral therapy (ART). Good adherence to ART is beneficial to patients and the public. Furthermore, mHealth has shown promise in improving HIV medication adherence globally.

OBJECTIVE

The aim of this meta-analysis is to analyze the effectiveness of mHealth on adherence to antiretroviral therapy in patients living with HIV.

METHODS

Randomized controlled trials (RCTs) of the association between mHealth and adherence to ART published until December 2021 were searched in electronic databases. Odds ratios (ORs), weighted mean differences, and 95% CIs were calculated. This meta-analysis was performed using the Mantel-Haenszel method or the inverse variance test. We evaluated heterogeneity with the I2 statistic. If I2 was ≤50%, heterogeneity was absent, and a fixed effect model was used. If I2 was >50%, heterogeneity was present, and a random effects model was used.

RESULTS

A total of 2163 participants in 8 studies were included in this meta-analysis. All included studies were RCTs. The random effects model was used for a meta-analysis of the effects of various intervention measures compared to routine nursing; the outcome was not statistically significant (OR 1.54, 95% CI 0.99-2.38; P=.05). In the subgroups, only short messaging service (SMS)-based interventions significantly increased adherence to ART (OR 1.76, 95% CI 1.07-2.89; P=.03). Further analysis showed that only interactive or bidirectional SMS could significantly increase ART adherence (OR 1.69, 95% CI 1.22-2.34; P=.001). After combining the difference in CD4 cell count before and after the interventions, we concluded that there was no statistical heterogeneity among the studies (I2=0%; tau2=0.37; P=.95).

CONCLUSIONS

Interactive or bidirectional SMS can enhance intervention effects. However, whether mHealth can improve adherence to ART in patients with HIV needs further study. Owing to a lack of the required significant staff time, training, and ongoing supervision, there is still much more to do to apply mHealth to the clinical use of ART for patients living with HIV.

A Systematic Review of Digital Interventions to Improve ART Adherence among Youth Living with HIV in sub-Saharan Africa

An estimated 3.4 million youth aged 15-24 years live with human immunodeficiency virus (HIV), a majority of whom reside in sub-Saharan Africa (SSA). Youth living with HIV (YLHIV) generally maintain lower levels of antiretroviral therapy (ART) adherence compared to other age groups, which has negative impacts on long-term clinical outcomes. Given expanding mobile phone and Internet usage among youth in SSA, and a need for strategies to increase ART adherence, this review systematically assessed whether digital interventions could be used to improve YLHIV ART adherence in SSA. PRISMA 2020 guidelines were followed, and PubMed and Scopus databases were searched using terms to reflect the population of interest and different digital intervention strategies to improve ART adherence. Experimental or quasi-experimental studies in SSA evaluating the quantitative effect of digital interventions on YLHIV ART adherence were included. 3849 articles and abstracts, and 122 full texts were screened by two researchers (KG and RM). A third researcher (AC) resolved conflicts. Data were extracted from six eligible articles published between 2017 and 2021. Interventions from included studies lasted 13-96 weeks and took place in Kenya, Nigeria, Uganda, and Zimbabwe. Two of the six studies found significant intervention-related improvements in viral suppression. Of these two studies, one used short message service (SMS) for appointment and daily adherence reminders, and the other combined weekly SMS reminders with phone calls, support groups, home visits, and clinic-based counseling. The four remaining studies, using SMS and Internet-based interventions, did not find any significant adherence-related improvements. This review provides mixed evidence for using digital interventions to improve ART adherence among YLHIV in SSA. Given the relative novelty of using digital interventions in this context, further research is required to evaluate their effectiveness in improving youth ART adherence.
