Adherence of the private sector to national tuberculosis guidelines in the Islamic Republic of Iran, 2001-02.

We determined the knowledge and practice of private sector physicians in three cites regarding management of pulmonary tuberculosis (TB) and their determinants. A random sample questionnaire survey was conducted of 732 private physicians. Stratified analysis and logistic regression were used to identify the adjusted determinants of the two outcomes. A high proportion of the doctors had correct knowledge about the major diagnostic criteria but there was a low level of knowledge and practice of TB management. Significant risk factors for poor knowledge were age > or = 36 years, being a GP rather than a specialist and no attendance in TB training courses or attendance in courses held by institutions other than the public health system. Age > or = 36 years was the only significant risk factor for poor practice.
