简要总结
With an estimated 60,000 people diagnosed with TB (Tuberculosis) annually, Uganda holds the 16th position of the 22 countries with highest cases of TB in the world. The Uganda national target of utilizing the DOTS (Direct Observed Treatment Short Course) to successfully treat 85% of patients diagnosed with TB has not been met. Currently, the country only detects 49.6% TB case detection, of which it successfully treats 73%. The DOTS strategy has suffered many socioeconomic challenges, which have resulted into its abandonment by many of the Ugandan hospitals. Poor TB medication adherence greatly attribute to the many cases of TB in Uganda. Causes of non-adherence to TB medication include lack of patient follow-up, patients' lack of transport to go to the clinics to pick up drugs, patients' forgetfulness. There is evidence that real time adherence monitoring linked with SMS reminders and social support notifications can address barriers to sustained ART (antiretroviral therapy) adherence. Such novel interventions addressing TB medication adherence challenges in low resource settings to date are limited. The prevailing SMS-based studies for TB medication adherence report mixed results, do not strategically link interventions with missed doses, and have largely been implemented in developed countries. To date, little is known about the use of real-time adherence monitoring technologies for TB medication adherence in resource-limited settings.
The goal of this research is to investigate the use of real time adherence monitoring technology linked with SMS reminders and notifications for TB medication adherence in rural southwestern Uganda.
The investigator will develop and quantitatively test a real-time adherence monitoring intervention with 60 individuals initiating TB treatment, and 40 social supporters. The investigator will randomize participants (1:1:1) to the following arms: 1) Fixed and linked SMS reminders, 2) SMS notifications to social supporters, and 3) no SMS (control). All participants will have adherence monitored in real-time for 6 months.
详细描述
This study has three major aims (Aims 1, 2 and 3)
Aim 1: Carry out a formative qualitative study to assess barriers and facilitators to TB medication adherence, and identify optimal SMS reminders, notifications, and initial feasibility of real time adherence monitoring. 35 TB patients will be recruited from the TB clinic in Mbarara Regional Referral Hospital (MRRH), and up to 15 social supporters specified by the TB patients (one per TB patient). Drawing from technology adoption and behavioral change models, the investigator will use semi-structured interviews to assess the initial feasibility and acceptability of the intervention, as well the barriers and facilitators to TB medication adherence, and how they can be addressed using the proposed intervention. The purpose will be to inform the development the technology necessary to conduct a real-time intervention involving a wireless monitor and SMS reminders and notifications (Aim 2 and 3).
Aim 2: Develop a TB medication adherence intervention based on SMS reminders (fixed and/or linked to real-time detection of missed doses) and assess its acceptability, feasibility and preliminary impact on adherence.
The Investigators will use real-time electronic adherence monitoring (i.e., Wisepill) to follow 60 TB-infected individuals initiating TB treatment in Mbarara Regional Referral Hospital (MRRH) for six months. Using a 1:1:1 manner, participants will be randomized to one of the following three study arms (details of each intervention will be informed by the data collected in Aim 1):
- Intervention Arm A: SMS reminders on a fixed schedule
- Intervention Arm B: SMS reminders linked to missed doses
- Control: No SMS reminders.

主要结局
Percent adherence
时间窗: 12 Weeks
SPSS (statistical package for social scientists) will be used, to determine the mean (standard deviation), median (interquartile range), number of late doses, number of missed doses, and number of hour gaps in adherence as determined by Wisepill for each stage of the intervention, as well as for the control group. The Investigator will compare adherence during each type of SMS reminder with adherence during the matched time period for the control group using T-tests (or Mann-Whitney U tests, depending on the normality of the data) for continuous data and chi-squared tests for categorical data.
