Objective
There is limited evidence on whether growing mobile phone availability in sub-Saharan Africa can be used to promote high adherence to antiretroviral therapy (ART). This study tested the efficacy of short message service (SMS) reminders on adherence to ART among patients attending a rural clinic in Kenya.
Design
A randomized controlled trial of four SMS reminder interventions with 48 weeks of follow-up.
Methods
Four hundred and thirty-one adult patients who had initiated ART within 3 months were enrolled and randomly assigned to a control group or one of the four intervention groups. Participants in the intervention groups received SMS reminders that were either short or long and sent at a daily or weekly frequency. Adherence was measured using the medication event monitoring system. The primary outcome was whether adherence exceeded 90% during each 12-week period of analysis and the 48-week study period. The secondary outcome was whether there were treatment interruptions lasting at least 48 h.
Results
In intention-to-treat analysis, 53% of participants receiving weekly SMS reminders achieved adherence of at least 90% during the 48 weeks of the study, compared with 40% of participants in the control group (P=0.03). Participants in groups receiving weekly reminders were also significantly less likely to experience treatment interruptions exceeding 48 h during the 48-week follow-up period than participants in the control group (81 vs. 90%, P = 0.03).
Conclusion
These results suggest that SMS reminders may be an important tool to achieve optimal treatment response in resource-limited settings.
Antiretroviral treatment of adult Kenyans in this cohort resulted in significant and persistent clinical and immunological benefit. These findings document the viability and effectiveness of large-scale HIV treatment initiatives in resource-limited settings.
Community-based care by PLWAs resulted in similar clinical outcomes as usual care but with half the number of clinic visits. This pilot study suggests that task-shifting and mobile technologies can deliver safe and effective community-based care to PLWAs, expediting ART rollout and increasing access to treatment while expanding the capacity of health care institutions in resource-constrained environments.
Women in resource-constrained settings are not necessarily disadvantaged in their access to HAART. More attention needs to be paid to ensuring that HIV-infected men are seeking care and starting HAART.
Aims
Dual epidemics of HIV and alcohol use disorders, and a dearth of professional resources for behavioral treatment in sub-Saharan Africa, suggest the need for development of culturally relevant and feasible interventions. The purpose of this study was to test the preliminary efficacy of a culturally adapted 6-session gender-stratified group cognitive-behavioral therapy (CBT) intervention delivered by paraprofessionals to reduce alcohol use among HIV-infected outpatients in Eldoret, Kenya.
Design
Randomized clinical trial comparing CBT against a usual care assessment only control
Setting
A large HIV outpatient clinic in Eldoret, Kenya, part of the Academic Model for Providing Access to Healthcare collaboration
Participants
75 HIV-infected outpatients who were antiretroviral (ARV)-initiated or ARV-eligible and who reported hazardous or binge drinking
Measurements
Percent drinking days (PDD) and mean drinks per drinking days (DDD) measured continuously using the Timeline Followback
Findings
There were 299 ineligible and 102 eligible outpatients with 12 refusals. Effect sizes of the change in alcohol use since baseline between the two conditions at the 30-day follow-up were large (d=.95, p=.0002, mean difference=24.93 (95% CI: 12.43, 37.43) PDD; d=.76, p=.002, mean difference=2.88 (95% CI: 1.05, 4.70) DDD). Randomized participants attended 93% of the 6 CBT sessions offered. Reported alcohol abstinence at the 90-day follow-up was 69.4% (CBT) and 37.5% (usual care). Paraprofessional counselors achieved independent ratings of adherence and competence equivalent to college-educated therapists in the U.S. Treatment effect sizes were comparable to alcohol intervention studies conducted in the U.S.
Conclusions
Cognitive-behavioral therapy can be successfully adapted to group paraprofessional delivery in Kenya and may be effective in reducing alcohol use among HIV-infected Kenyan outpatients.

We evaluated performance, accuracy, and acceptability parameters of unsupervised oral fluid (OF) HIV self-testing (HIVST) in a general population in western Kenya. In a prospective validation design, we enrolled 240 adults to perform rapid OF HIVST and compared results to staff administered OF and rapid fingerstick tests. All reactive, discrepant, and a proportion of negative results were confirmed with lab ELISA. Twenty participants were video-recorded conducting self-testing. All participants completed a staff administered survey before and after HIVST to assess attitudes towards OF HIVST acceptability. HIV prevalence was 14.6 %. Thirty-six of the 239 HIVSTs were invalid (15.1 %; 95 % CI 11.1–20.1 %), with males twice as likely to have invalid results as females. HIVST sensitivity was 89.7 % (95 % CI 73–98 %) and specificity was 98 % (95 % CI 89–99 %). Although sensitivity was somewhat lower than expected, there is clear interest in, and high acceptability (94 %) of OF HIV self-testing.
