Factors that effect sputum culture conversion rate in hospitalized patients with pulmonary tuberculosis who were applied directly observation therapy and non-directly observation therapy.

Directly observation therapy (DOT) has been accepted as the basic method for controlling tuberculosis. The present study aimed to determine the risk factors that affect sputum culture conversion rate in the DOT managed and non-DOT managed hospitalized patients. The study was included 50 cases with positive sputum cultures between the dates April 2001-April 2002 when DOT was not applied and 60 cases between the dates May 2002-May 2003 when DOT was applied.
