Summary

Multidrug-resistant tuberculosis (MDR-TB) outbreaks in hospitals can be prevented. Implementing infection control measures, including isolation and protective equipment, is crucial for controlling TB transmission.

Area of Science:

  • Infectious Diseases
  • Public Health
  • Hospital Epidemiology

Background:

  • A significant number of multidrug-resistant tuberculosis (MDR-TB) cases were acquired between 1989 and 1990.
  • Patient exposure occurred in a shared ward with an acid-fast bacillus smear-positive pulmonary tuberculosis case.
  • Infectious patients were often not isolated until sputum smears turned positive, highlighting a critical delay in containment.

Purpose of the Study:

  • To describe the risk assessment and control measures implemented in response to an MDR-TB outbreak.
  • To detail the development and institution of a comprehensive tuberculosis control program.
  • To share the experiences and challenges encountered during the implementation of TB control strategies.

Main Methods:

  • Conducted a risk assessment to identify transmission pathways.
  • Instituted administrative and environmental controls to limit TB spread.
  • Implemented ongoing education programs, use of personal protective equipment, and enhanced employee health testing.

Main Results:

  • The study identified a ward-based outbreak of MDR-TB involving 26 patients.
  • Delayed isolation of infectious patients was a key factor in transmission.
  • The implemented tuberculosis control program aimed to prevent future occurrences.

Conclusions:

  • Prompt recognition and intervention are vital for controlling hospital-acquired MDR-TB.
  • A multi-faceted approach including administrative, environmental, and personal protective measures is effective.
  • Ongoing vigilance and robust infection control protocols are essential for preventing TB transmission in healthcare settings.
