NCT03836625

Brief Summary

Population mobility is common in South Africa, but important research gaps exist describing this mobility and its impact on engagement in HIV care, particularly among pregnant and postpartum women. Through this study, the investigators propose to test a smartphone application - CareConekta - to conduct essential formative work on mobility and evaluate this app as an intervention to facilitate engagement in HIV care during times of mobility. This work is critical to adapting CareConekta for widespread use, providing critical information about mobility during the peripartum period and the impact on engagement in HIV care, and piloting this intervention to improve engagement.

Outcome Measures

Primary Outcomes (3)

  • Mobility Prevalence

    The investigators will report the number of participants who travel during the study period (defined as 3 or more nights away from home), over the denominator of all participants who completed follow-up.

    Baseline to End of Study (up to 2 years)

  • Median Number of Trips Per Person

    Among those who travel, the investigators will report the median and interquartile range number of trips during the study period.

    Baseline to End of Study (up to 2 years)

  • CareConekta Feasibility: Same Phone at Follow-up

    The number of participants who report using the same phone from enrollment at follow-up

    Baseline to End of Study (up to 2 years)

Secondary Outcomes (10)

  • Timing of Travel

    Baseline to End of Study (up to 2 years)

  • Permanent Move

    Baseline to End of Study (up to 2 years)

  • CareConekta Feasibility: GPS Disabled During the Study Period

    Baseline to End of Study (up to 2 years)

  • CareConekta Feasibility -- Participant Reported Sharing Phone

    Baseline to End of Study (up to 2 years)

  • CareConekta Feasibility -- Participant Ever Opened App

    Baseline to End of Study (up to 2 years)

  • +5 more secondary outcomes

Study Arms (2)

Control

NO INTERVENTION

The control arm will receive standard CareConekta, which will track their mobility with no additional features.

Intervention

EXPERIMENTAL

The intervention arm will receive standard CareConekta, plus text notifications of nearby ART facilities when they have traveled \>50 km from the study site for \>7 days. At enrollment, participants in the intervention arm also will be able to opt-in to phone call(s) and/or WhatsApp message(s) from study staff to when they have met this travel threshold. The study staff calls and messages will ask about medication supply and will provide assistance with nearby facilities, if requested.

Other: CareConekta

Interventions

CareConekta is a smartphone app that uses the phone's GPS to prospectively characterize mobility and allow for intervening in real-time. CareConekta uses the phone's built-in GPS system to record location coordinates.

Limitations and Caveats

We found that several key challenges impeded our study feasibility. The primary challenge is that during the study period, no participant's smartphone recorded at least one heartbeat per day.
