Improving Outcomes in HIV Patients Using Mobile Phone Based Interactive Software Support

Improving Outcomes in HIV Patients Using Mobile Phone Based Interactive Software Support

Current estimates point towards a huge increase in the number of people that are eligible to start ART in Uganda and globally. As many of the newly eligible patients are largely asymptomatic, there are concerns about adherence and retention of these individuals and especially those starting ART with a higher CD4 counts. Urgent information is required to plan for implementation of most recent WHO and National guidelines in the most cost effective manner as well as maximizing retention of HIV positive individuals in care and achieving virological suppression.

The investigators plan to undertake research designed to see if investigators can optimize adherence, virological outcomes and HIV knowledge, in order to give an overall increased quality of life in vulnerable populations starting or established on ART in Kampala, Uganda. The investigators will test implementation of an open source software-based tool to send text messages and to give access to an interactive voice response system using patients' mobile phones.

The investigators' aim to undertake an open labelled randomised trial at two sites: the IDI which is an urban centre of excellence in HIV care, and Kasangati Health Centre, which is a peri-urban public health care facility. The project aims to enrol HIV positive patients starting ART, already established on first line ART or switching to second line ART, including special populations (pregnant women, discordant couples and young people). The estimated length of the project is 30 months. The technology to be evaluated in this study is based on CONNECT FOR LIFETM m-health technology (CFL2015.01 or higher), which provides text messages or Interactive Voice Response (IVR) functionalities, and allows a computer to interact with humans through the use of voice and tones input via keypad and offers pill reminders, clinic visit reminders, health tips and support symptom reporting.

Primary Objective is to determine the effect of the CFL2015.01 tool on quality of life of HIV patients receiving care at IDI and Kasangati HCIV. At the start of the intervention, all patients will undergo quality of life assessment, which will be repeated at months 6, 12, 18 and 24 months. The scores will be compared to assess the effect of the tool on quality of life. The Secondary Objectives are virological outcomes baseline, 6, 12,18 and 24 months, retention in care, aversion of early treatment failure, disease knowledge, clinic attendance and cost analysis.

CALL FOR LIFE UGANDATM Janssen Global Public Health Research and Development, in close collaboration with the Infectious Disease Institute Kampala (IDI), has developed Call for Life Uganda tailored to the needs of PLHIV in Uganda. Call for Life UgandaTM is based on the CONNECT FOR LIFETM technology (CFL2015.01 or higher version) and the MOTECH platform, an open source platform developed by Grameen Foundation and the University of Southern Maine with financial support from the Bill and Melinda Gates Foundation, and was released under the terms of the MOTECH open source license agreement.

All patients consenting will; At enrolment receive detailed information from a nurse/counsellor on the Call for Life UgandaTM system and how it operates Receive calls or text messages from Call for Life UgandaTM will include recording of self-reported adherence (soliciting active feedback via keypad) and symptom management triggering alerts for the clinic.

STUDY PROCEDURES Screening The subjects will be screened and enrolled over a period of 6 months These are the screening procedures oAll consecutive eligible patients will be approached for participation in the study.

oFor patients interested in participating the inclusion and exclusion criteria will be ascertained.

oThe patients will receive information about the study by the study nurse or counselor Patients who agree to participate in the study will sign the informed Follow-up Visit The participants will come to the clinic monthly or 2 monthly to pick up their ART and concomitant medications (non-study visits).

The participants will come for their study follow up visits every 6 months Every 6 months The patients will be assessed by the study staff.

• The study doctor will collect General Medical History and perform Physical Examination and enter it in an electronic CRF.
• The counsellor will collect the Quality of life and Knowledge questionnaires and enter them in an electronic CRF.

At baseline, 6, 12,18 and 24 months the following samples will be collected;

• Viral load
• Storage plasma (1 aliquot) serum (3 aliquots)

Additional procedures Resistance testing: It will be done on stored samples

• Baseline Resistance testing will be carried out if subsequent viral failure in order to investigate transmitted resistant virus
• Biological samples will also be stored at 6, 12,18 and 24 months and resistance testing carried out in case of viral load >1,000 copies/ml

Subject Withdrawal Subjects may withdraw from the study at any time at their own request, or they may be withdrawn at any time at the discretion of the investigator for safety or behavioral reasons, or the inability of the subject to comply with the protocol required schedule of study visits or procedures.

SAFETY ASSESSMENT Safety monitoring for this study will focus on unanticipated problems involving risks to participants, including unanticipated problems that meet the definition of a serious adverse event.

DATA ANALYSIS/STATISTICAL METHODS Based on a pre and post ART assessment in Burkino Faso and Uganda, it is anticipated that the quality of life score (MOS-HIV) in ART naïve patients will increase at least by 15 points for physical health summary (PHS) between baseline and 12 months ART use. We estimate there will be an additional 5 points improvement in those receiving C4LTM which would give 20-point improvement for those on C4LTM and 15 points for those not on call for Life. In those already on ART, investigators estimate an improvement for those established on ART with a 5-point improvement for those on C4LTM and nil for those not accessing C4LTM. We also estimate a 5-point increase in mental health score in those receiving C4LTM compared to no change in those without C4LTM starting ART, and a lower improvement of 2 points in mental health score in those already on ART. The study is powered on the PHS for QOL. For a power of 0.9 and precision of 0.05 we would need a minimum of 273 in each arm (overall 546) patients, if the mean PHS among patients with C4L was 58.2 compared to 55.2 among patients without C4L. The investigators will include a 10% LTFUP/mortality rate to give a sample size of 600.

The composition of the study participants is estimated as 300 patients at Kasangati and 300 patients at IDI. With the proposed sample size, the numbers above depict over 90% power to test even the smallest differences in mean PHS at 12 months in the group of patients with and without C4L. The investigators also anticipate that it is possible to detect changes in MHS QOL with this sample Analysis of Primary Endpoint Scales to measure quality of life For this study we have chosen to use the Medical Outcomes Study (MOS-HIV) Health Survey which is the most widely used health related HRQoL measure in PLHIV.

The MOS-HIV scale was chosen because it has been validated in various settings including Uganda, has a Luganda language version, and was found to be useful in assessing HRQoL in PLHIV.

The MOS-HIV measures HRQoL in 11 areas: health perceptions, bodily pain, physical function, role function, social function, mental function, vitality, health distress, cognitive function, QoL, and health transition. One scores scale in a range from 0-100 with a higher score implying better health (41). In addition to these subscales, a Physical Health Summary score (PHS) and Mental Health Summary score (MHS) can be calculated.

Intra patient in QoL scores will be compared using Paired T-tests and overall change will be investigated. The effect of calendar time on QoL life scores will be accounted for during analysis. Furthermore, the changes and or effect of the intervention on different sub-groups of HIV positives patients will be carried. The effect of the intervention will also be compared between IDI and Kasangati sites. All analysis will be conducted using STATA, USA.

• Investigators will assess perceptions and attitudes to the Call for Life UgandaTM tool thorough focus group discussions and Key informant interviews, targeting each special population. We will use purposeful sampling and will continue until no new themes emerge. We will use NVIVO software for coding of themes.
• Cost analysis along with the study evaluation; appropriate and detailed cost evaluation will also be performed. It is anticipated that if the intervention is proved effective, a cost effective analysis would contribute to developing a sustainable scale up strategy for similar service across Uganda.

RADOMISATION Patients will randomly be assigned to either one of the two arms, that is, with and without CFL. To ensure that all patients in each of the arms are represented and equally balanced out in both arms, the study will use stratified randomization where each of the categories of patients at the start of the study will form the strata on interest. Within each stratum, the patients will be randomly assigned to C4L or no C4L. Randomization lists will be generated by an independent statistician and kept under lock and key in the two sites.

DATA PRIVACY Any and all data generated in IDI's use of Call for Life UgandaTM shall be owned solely by IDI. Therefore, IDI will take all reasonable steps to restrict disclosure of personal data including patient-identifiable to third parties.

In addition, the following Security Measures are in place to protect Patient's privacy when using Call for Life UgandaTM
