The WelTel Trial in context and the importance of null findings

What do meta-analysts need in primary studies? Guidelines and the SEMI checklist for facilitating cumulative knowledge

Meta-analysis is often recognized as the highest level of evidence due to its notable advantages. Therefore, ensuring the precision of its findings is of utmost importance. Insufficient reporting in primary studies poses challenges for meta-analysts, hindering study identification, effect size estimation, and meta-regression analyses. This manuscript provides concise guidelines for the comprehensive reporting of qualitative and quantitative aspects in primary studies. Adhering to these guidelines may help researchers enhance the quality of their studies and increase their eligibility for inclusion in future research syntheses, thereby enhancing research synthesis quality. Recommendations include incorporating relevant terms in titles and abstracts to facilitate study retrieval and reporting sufficient data for effect size calculation. Additionally, a new checklist is introduced to help applied researchers thoroughly report various aspects of their studies.

Lessons learned from a mobile technology-based intervention informed by behavioral economics to improve ART adherence among youth in Uganda

Evidence suggests that simple text messaging interventions may not suffice to improve ART adherence among youth in low-resource settings. To address this shortcoming, we developed an intervention that shared weekly real-time adherence feedback to youth in Uganda using short message services (SMS), based on information tracked by an electronic device (Wisepill). We present results from 7 formative and 6 exit focus groups (FGs) in Mulago and Entebbe, Uganda with youth ages 15-24, providers, and Community Advisory Board members. Participants consistently conveyed positive impressions of Wisepill, noting that it helped store their medications, facilitated travel, served as a reminder, and motivated adherence. Participants raised phone-related issues before the study; most were addressed but some remained (e.g., limited network access, electricity for powering phones). Further, they highlighted the importance of carefully crafting text messages (e.g., use slang rather than potentially stigmatizing words) and viewed personalizing messages favorably but were divided on the desirability of including their name in study-related texts. Exit FGs confirmed that sharing group adherence levels with participants tapped into the competitive spirit common among youth. Our results suggest future mobile technology-based interventions can be improved by providing messages that go beyond simple reminders to provide individual and group-level adherence feedback.

Supporting Adolescents to Adhere (SATA): Lessons learned from an intervention to achieve medication adherence targets among youth living with HIV in Uganda

INTRODUCTION

Youth in Uganda are disproportionately impacted by HIV and report significant barriers to ART adherence. We asked participants how fixed versus flexible adherence target setting for incentive interventions, in combination with other support systems, could help HIV-positive youth in Uganda reach medication adherence targets.

METHODS

Four focus groups conducted in Luganda were audiotaped, transcribed, and translated into English; the transcriptions were then coded using Dedoose software. Two members of the research team read the text and identified the basic topics covered. A codebook was developed that detailed inclusion and exclusion criteria for each topic area, as well as typical entries for each code. A directed content analysis was used to identify key themes.

RESULTS

Several themes were common across groups. Participants consistently maintained that they preferred to set their own adherence targets. But regardless of how adherence targets were assigned, participants noted that missing their target was disappointing. They commented positively on the use of Medication Event Monitoring System (MEMS) caps, noting that knowing their adherence information was being tracked often encouraged them to take their medications. Participants reported that receiving text messages further motivated them to take their medications; however, on occasions when they reported not doing well, they wanted intensive follow-up by staff. Participants said that the prize drawing alone did not motivate their ART adherence and that receiving 'zero' in the drawing was disheartening.

CONCLUSION

We found that participants preferred to set their own adherence targets and that doing so increased a sense of ownership in achieving them. All participants enjoyed using MEMS caps and expressed disappointment at needing to return the device at the study's completion. Participants noted that text message reminders may be a useful way to help patients stay motivated between clinic visits; however, ongoing engagement and support are needed from providers and counselors. Finally, our participants stressed the importance of including incentives with a small, positive value rather than 0 when designing the lowest prize.

Effectiveness of text messaging interventions on prevention, detection, treatment, and knowledge outcomes for sexually transmitted infections (STIs)/HIV: a systematic review and meta-analysis

BACKGROUND

Rates of STIs continue to rise worldwide, and novel evidence-based interventions such as text messaging aimed at improving client services are needed. We conducted a meta-analysis to evaluate text messaging to support STI/HIV prevention and treatment interventions.

METHODS

We included articles that reported findings from randomized controlled trials (RTCs) involving adults and youth who were at risk of acquiring (or who currently had) a STI and/or HIV, a text message and comparator intervention, and reported provided outcome data on adherence to STI/HIV treatments. Articles were excluded if they were not published in English. We only included studies that have full-text publications so certainty and risk of bias assessments could be performed. Eight databases were searched to retrieve articles published between 1996 and March 2017. The Cochrane risk of bias tool was used and certainty of the evidence was assessed using GRADE. Effect estimates were pooled using a random effects model.

RESULTS

A total of 35 RCTs were found, 6 of which were considered at low risk of bias. Eight studies found an increased association using text messaging in appointments attended compared to standard care (OR 1.64, 95% CI 1.28 to 2.10). Participants receiving text messages had an increase in HIV testing compared to standard care (n = 6; OR 1.73, 95% CI 1.39 to 2.15). Ten text messaging RCTs measuring adherence using micro-electro-mechanical systems (MEMS) pill counts has a non-significant association (OR 1.17, 95% CI 0.95-1.45) while five studies measuring adherence by self-report was found to be significant (OR 1.64, 95% CI 1.28-2.11).

CONCLUSIONS

The effectiveness of text message interventions is equivocal. While text messaging has the potential to enhance the delivery of STI/HIV interventions, program planners are encouraged to evaluate any SMS intervention to ensure it is achieving the desired result.
