In response to a request from the Service Employees International Union, District 1199, an investigation was begun into potential exposures to Mycobacterium-tuberculosis at the Warren Correctional Institution (SIC-9223), Lebanon, Ohio. The facility housed about 1,300 inmates in 15 structures. An inmate had been diagnosed with active tuberculosis disease in May of 1992. At the time of the NIOSH evaluation, the patient was no longer considered to be infectious. Periodic tuberculosis screening was not provided for employees or inmates, but all inmates were screened at a reception center before arriving at the facility. Most of the air in the Medical Department was recirculated, allowing the potential for aerosolized M-tuberculosis to be transmitted throughout the department and into administrative offices as well. Other ventilation deficiencies which would increase the potential for spread of infections were also seen. These included incorrect pressure relationships between rooms and adjacent corridors. The authors conclude that the risk of M-tuberculosis transmission to employees was low or nonexistent at the time of the investigation, because the patient was no longer infectious. During a period where an inmate is actually infectious, there did appear to be cause for concern among the staff. The authors recommend that the potential for exposures should be reduced through ventilation system improvements and increased medical screening.
