Abstract
SETTING
Kenyatta National Hospital (KNH), Nairobi, Ken-ya, a large referral and teaching hospital.
OBJECTIVE
1) To document tuberculosis (TB) case notification rates and trends; 2) to describe demographic, clinical and workplace characteristics and treatment outcomes; and 3) to examine associations between demographic and clinical characteristics, HIV/AIDS (human immunodeficiency virus/acquired immune-deficiency syndrome) treatment and anti-tuberculosis treatment outcomes among hospital workers with TB at KNH during the period 2006-2011.
DESIGN
A retrospective cohort study involving a review of medical records.
RESULTS
The TB case notification rate among hospital staff ranged between 413 and 901 per 100 000 staff members per year; 51% of all cases were extra-pulmonary TB; 74% of all cases were among medical, paramedical and support staff. The TB-HIV coinfection rate was 60%. Only 75% had a successful treatment outcome. Patients in the retreatment category, those with unknown HIV status and those who were support staff had a higher risk of poor treatment outcomes.
CONCLUSION
The TB case rate among hospital workers was unacceptably high compared to that of the general population, and treatment outcomes were poor. Infection control in the hospital and management of staff with TB requires urgent attention.
