About the study
Patient retention in care (continuing to see their medical professional) and adherence to treatment (following the treatment program) leads to better health outcomes for patients and is important to the success of HIV care programs. Unfortunately, many patients do not consistently remain in care. Furthermore, low-income settings pose extra challenges to maintaining treatment because of increased barriers to access health care.
Cell phones provide new opportunities for communication between medical professionals and their patients. The purpose of this study is to determine if the use of cell phone text-messaging between clinic staff and individuals infected with HIV helps people stay in HIV care.
About the disease/condition
Access to antiretroviral therapy (ART), the most common treatment for HIV, continues to expand throughout sub-Saharan Africa, and research has shown that high levels of patient retention and adherence to treatment programs are very important to the success of HIV care. Yet, after 6 months, over 20% of patients in low-income areas are no longer on consistent treatment, and after 3 years, 35% are no longer on consistent treatment. Retention is even lower for patients who have not yet begun treatment. New communication technologies like cell phones give us new opportunities to develop strategies to improve treatment and communication between medical professionals and patients.
This study will recruit 700 participants who will be followed-up for 12 months. It will take place at two large health centres in Nairobi that offer HIV care and treatment. The clinics serve low-income populations that have minimal access to basic services such as running water, sanitation, and electricity. The participants will be randomly placed into one of two groups.
The first group of patients will use a cell phone to stay in contact with the medical team. The second group will receive standard care. Each group will have the same number of patients. If the use of cell phones is found to be more effective than standard care at retaining patients, the participants in the group receiving standard care will gradually be moved into the other group after the first phase of the study.
Individuals will be eligible for the study if they meet the following inclusion criteria:
- evidence of HIV infection
- undertaking an HIV test at the Kibera Community or Baba Dogo Health Centres
- own or have sufficient access to a cell phone; able to operate a cell phone using simple text-messaging (or have somebody text message on their behalf)
- able and willing to provide informed consent to participate
- previously taken or currently taking ART
- previously assessed for ART eligibility
