Factors Influencing Culture Outcomes in Patients with Persistent Smear-Positive Pulmonary Tuberculosis After Two Months of Treatment

Category	Detail
Condition	Persistent Smear-Positive Pulmonary Tuberculosis
Key Mechanisms	Airborne transmission, respiratory isolation, effective multidrug therapy
Target Population	Patients with smear-positive pulmonary TB remaining positive after two months of treatment
Care Setting	Inpatient respiratory isolation at specialized tuberculosis care centers

Prolonged smear positivity may indicate non-viable bacilli, leading to unnecessary isolation.
Patients with high-risk contacts should remain hospitalized under airborne isolation.
Psychological distress and socioeconomic challenges are significant for patients in prolonged isolation.
Culture and drug-susceptibility results are often delayed, complicating discharge decisions.
The study aims to refine isolation guidelines balancing infection control and patient well-being.

Perform AFB smear, GeneXpert, and culture with drug susceptibility testing for all suspected pulmonary TB cases.

Continue effective multidrug therapy and monitor treatment response through sputum cultures at 2 and 6 months.

Repeat sputum cultures routinely to detect resistance and assess treatment efficacy.

Prolonged isolation can lead to psychological distress, stigmatization, and socioeconomic challenges.

Pulmonary TB patients requiring inpatient respiratory isolation.

Effective therapy with Directly Observed Therapy (DOT) is crucial for management.

Ensure clinical stability and effective therapy before considering discharge.
Arrange appropriate follow-up for patients discharged from isolation.
Utilize multivariable logistic regression to identify predictors of culture conversion.
