We conducted a retrospective study to investigate the effectiveness of an mHealth messaging intervention aiming to improve maternal health and HIV outcomes. Maternal health SMSs were sent to 235 HIV-infected pregnant women twice per week in pregnancy and continued until the infant's first birthday. The messages were timed to the stage of the pregnancy/infant age and covered maternal health and HIV-support information. Outcomes, measured as antenatal care (ANC) visits, birth outcomes and infant HIV testing, were compared to a control group of 586 HIV-infected pregnant women who received no SMS intervention. Results showed that intervention participants attended more ANC visits (5.16 vs. 3.95, p < 0.01) and were more likely to attend at least the recommended four ANC visits (relative risk (RR): 1.41, 95% confidence interval (CI): 1.15-1.72). Birth outcomes of intervention participants improved as they had an increased chance of a normal vaginal delivery (RR: 1.10, 95% CI: 1.02-1.19) and a lower risk of delivering a low-birth weight infant (<2500 g) (RR: 0.14, 95% CI: 0.02-1.07). In the intervention group, there was a trend towards higher attendance to infant polymerase chain reaction (PCR) testing within six weeks after birth (81.3% vs. 75.4%, p = 0.06) and a lower mean infant age in weeks at HIV PCR testing (9.5 weeks vs. 11.1 weeks, p = 0.14). These results add to the growing evidence that mHealth interventions can have a positive impact on health outcomes and should be scaled nationally following comprehensive evaluation.

Background There are high expectations that mobile health (mHealth) strategies will increase uptake of health care services, especially in resource strained settings. Our study aimed to evaluate effects of an mHealth intervention on uptake of maternal health services. Methods This was an intervention cohort study conducted at six public antenatal and postnatal care clinics in inner-city Johannesburg, South Africa. The intervention consisted of twice-weekly informative and pregnancy stage-based maternal health information text messages sent to women during pregnancy until their child was one year of age. The intervention arm of 87 mother-infant pairs was compared to a control arm of 90 pairs. Univariate and multivariate analyses were used to compare the probability of the outcome between the two groups. Results Intervention participants had higher odds of attending all government-recommended antenatal and postnatal visits, all recommended first year vaccinations (OR: 3.2, 95% CI 1.63–6.31) and had higher odds of attending at least the recommended four antenatal visits (OR: 3.21, 95% CI 1.73–5.98). Conclusion We show an improvement in achieving complete maternal-infant continuum of care, providing evidence of a positive impact of informative maternal mHealth messages sent to pregnant women and new mothers.

Background South Africa provides free antiretroviral therapy for almost 5 million people living with HIV, but only 71% of the eligible people are on treatment, representing a shortfall in the care cascade, especially among men and youth. Many developing countries have expanded access to smartphones; success in health apps raises the possibility of improving this cascade. Objective SmartLink is a health app for Android smartphones providing HIV-related laboratory results, information, support, and appointment reminders to engage and link patients to care. This study aimed to evaluate the ability of SmartLink to improve linkage to care for HIV-positive smartphone owners. Methods This study was a multisite randomized controlled trial in Johannesburg. The intervention arm received the app (along with referral to a treatment site) and the control arm received the standard of care (referral alone). Linkage to care was confirmed by an HIV-related blood test reported on the National Health Laboratory Service database between 2 weeks and 8 months after initiation. Results A total of 345 participants were recruited into the study; 64.9% (224/345) of the participants were female and 44.1% (152/345) were aged less than 30 years. In addition, 46.7% (161/345) were employed full time, 95.9% (331/345) had at least secondary school education, and 35.9% (124/345) were from Zimbabwe. Linkage to care between 2 weeks and 8 months was 48.6% (88/181) in the intervention arm versus 45.1% (74/164) in the control ( P =.52) and increased to 64.1% (116/181) and 61.0% (100/164) ( P =.55), respectively, after the initial 8-month period. Moreover, youth aged 18 to 30-years showed a statistically significant 20% increase in linkage to care for the intervention group. Conclusions Youth aged less than 30 years have been historically difficult to reach with traditional interventions, and the SmartLink app provides a proof of concept that this population reacts to mobile health interventions that engage patients in HIV care.
