Summary
This review discusses hospital infection control for tuberculosis in Japan, focusing on a hierarchy of measures from local practices to personal protection. It also addresses challenges in detecting tuberculosis infections and selecting healthcare workers for isoniazid chemoprophylaxis.
Area of Science:
- Public Health
- Infectious Disease Control
- Occupational Health
Context:
- Tuberculosis (TB) incidence in Japan was 31.0/10,000 population in 2000, with hotspots like Osaka exceeding 61.5/10,000.
- The endemic nature of TB in certain Japanese regions necessitates robust hospital infection control strategies.
Purpose:
- To review effective hospital infection control practices for tuberculosis in high-incidence areas of Japan.
- To discuss challenges in TB detection and chemoprophylaxis selection for healthcare workers in Japan.
Summary:
- A hierarchy of TB infection control measures is proposed: local control, administrative controls, engineering controls (preventing droplet nuclei spread), and personal protection (e.g., N95 respirators).
- The widespread Bacillus Calmette-Guérin (BCG) vaccination policy complicates tuberculosis detection using the tuberculin skin test in Japan.
- Strategies for selecting healthcare workers for isoniazid chemoprophylaxis are examined due to difficulties in identifying infected individuals.
Impact:
- Provides a framework for implementing comprehensive TB infection control in Japanese hospitals.
- Offers insights into managing occupational risks for healthcare workers in TB-endemic settings.
- Informs policy and practice regarding TB screening and preventive treatment for healthcare personnel.
