- Brief Summary
Despite increased emphasis on evidence based practice in recent years a gap remains between evidence and practice, particularly in resource poor countries. Few studies to date have examined the use of knowledge translation strategies to improve health care outcomes in low income countries. However, given that the majority of health care in these settings is provided by workers with less training and limited resources, the theoretical potential for knowledge translation strategies to improve health care delivery and outcomes by integrating best evidence into routine practice may be greatest in these settings.
Knowledge translation (KT) is an approach to changing health care provider behavior to reduce the gap between evidence and practice in health care delivery. There has been a tendency for knowledge translation interventions to employ generic, "off the shelf", strategies, and apply them to deal with specific issues. This generic approach, fails to recognize the variability in the specific characteristics of health care settings, in terms of their patient populations, health care systems, and health care providers. These characteristics, whether they function as barriers or facilitators to change, make a generalized approach to KT ineffective, where a tailored strategy, which specifically adjusts its approach to measured local barriers and facilitators may achieve better alignment of practice to evidence. This is likely to be particularly true in low income countries where the majority of health care is provided by non-physician health care workers, working within a wider range of health care systems, with variable and unique patient populations and resource constraints. Given the potential to significantly impact health care outcomes at relatively low cost, further research is needed both to develop methods for identifying potential barriers and facilitators to KT strategies in specific resource poor settings, and to evaluate the effectiveness of KT strategies tailored to address the identified barriers.
This study will assess the effectiveness of a two part knowledge translation intervention tailored to address factors identified in a previous study as functioning as barriers and facilitators to treatment adherence among patients on treatment for tuberculosis or combined tuberculosis and antiretroviral treatment, targeting improved patient adherence and health outcomes, in a specific low income country.

- Primary Outcome Measures
Name Time Method Proportion of patients classified as successfully treated. 1 year Treatment success is defined as cure or treatment completion. Outcomes measured at patient level at end of treatment (6 months), and at 1 year at health center level (randomized at level of health center)
- Secondary Outcome Measures
Name Time Method Proportion of patients defaulting from treatment. 1 year Default defined as missing greater than or equal 2 consecutive months of treatment. Outcome measured at patient level at end of treatment (6 months), and 1 year at level of health center (randomized at level of health center).
Proportion of successfully treated and default cases among patients treated for tuberculosis only and those on both tuberculosis and antiretroviral treatment 1 year Treatment success defined as cure or treatment completion. Outcome measured at patient level at end of treatment (6 months), and at 1 year for the the health center (randomized at level of health center)
Weight change. 1 year Weight change from start to end of treatment. Outcome measured at patient level throughout treatment (6 months) and at 1 year at the health center level (randomized at level of health center).
