Abstract

Investigators with the HHE Program evaluated employee exposure to Mycobacterium tuberculosis at a long-term care facility. Managers asked for assistance in identifying disease sources and assessing the ventilation system. HHE Program investigators interviewed 216 employees, reviewed employee health records, and reviewed medical records of 53 residents in one area of the facility. The records showed that 12 residents and 16 employees had latent tuberculosis infection. One resident had active pulmonary tuberculosis disease, which was the likely source of latent tuberculosis infection among 8 residents and 16 employees. Investigators did not observe a clear pattern between the ventilation system and tuberculosis transmission. HHE Program investigators recommended that residents be monitored clinically for signs and symptoms of active tuberculosis disease at least once a month and that tuberculosis screening for residents, employees, and direct care volunteers in the area of concern be continued at least every 6 months. Employees with a prior negative skin test should get a tuberculin skin test every year and employees with positive tuberculin skin test in the past should have a medical evaluation for tuberculosis every year. The ventilation system should be upgraded to provide improved filtration in resident areas and air temperatures kept in accordance with current guidelines for nursing homes.
