Reflections on tuberculosis diagnosis and treatment outcomes in Ghana

Abstract

Background: Available evidence in Ghana shows the implementation of tuberculosis (TB) control activities efforts since the beginning of the 1900s. In spite of that, TB continues to be one of the common diseases in the country. In 1994, local and international policy windows opened for renewed strategies for the control of TB. This paper explores some of the approaches which have been in place since 1994 and their implications for treatment outcomes.

Methods: The study combines quantitative and qualitative data. The quantitative data consist of treatment outcome from 1997-2010 and the qualitative data are derived from in-depth interviews with some staff of the TB control programme. Poisson regression and inductive coding were applied to the quantitative and qualitative data respectively.

Results: Reported cure rates increased from 43.6% to 87.7% between 1997 and 2010. The data from the in-depth interviews (IDIs) suggested that improvements in diagnosis, community TB care, stigma reduction among community and health workers towards TB patients, the public-private partnership, and the enablers' package contributed to the improved better treatment outcomes, particularly from 2008.

Conclusions: Lessons learnt include the achievement of objectives with varying strategies and stakeholder interventions. Further studies would be needed to quantify the contributions of the various interventions to help determine those that are cost effective as well as efficient and effective for TB control.
