 This study assessed the quality of private sector TB care in Nigeria by comparing it to public sector care. The study found that while private sector providers did not perform better than public sector providers overall, they did demonstrate comparable levels of performance in certain areas such as screening for TB symptoms. Additionally, the study identified specific areas where private sector providers could improve their TB care, including collecting sputum samples from presumptive cases and providing adequate counseling during treatment initiation. These findings suggest that private sector providers are capable of playing a significant role in improving TB care in Nigeria.
