The status of tuberculosis infection control measures in health care facilities rendering joint TB/ HIV services in “German Leprosy and Tuberculosis Relief Association” supported states in Nigeria
AbstractObjective: To assess the status of tuberculosis (TB) infection control practice in health care facilities implementing joint TB/HIV activities.
Materials and Methods: A descriptive survey triangulating self-administered questionnaire (facility survey to Infection Control Officer, individual health worker to general health workers), review of facility case notes and participant observation techniques was carried out. Twelve health facilities from southern Nigeria were assessed.
Results: (1) Administrative and work practice control measure: Only 1 (8.3%) facility had a documented TB Infection control policy; 2 (16.7%) facilities had Infection Control Committee; 5 (41.7%) facilities had Infection Control Officer; 2 (16.7%) asked questions at the health records about cough; 1 (8.3%) facility had health workers intermittently checking for patients with cough in the waiting hall; and 2 (16.7%) facilities had Infection Control Officers who have attended some training on infection control. No facility had Information, Education and Communication (IEC) materials reminding patients and health workers of the possibility of TB transmission in the health care setting. While 86.4% of TB patients were screened for HIV, only 54.7% of HIV patients were tested for TB. (2) Environmental control measures: All the waiting halls were well ventilated. Though 66.7% of the consulting rooms were well ventilated, 25% of them were over crowded; 58.3% of the facilities managed sputum smear positive TB patients in the same ward with HIV-positive and other vulnerable patients; no facility had air cleaners.
Conclusion: Implementation of the different aspects of the administrative control and work practice component of TB infection control measure range from 8.3% to 41.7% of the facilities. Urgent measures should be taken to reverse this trend in the face of TB burden due to HIV.
