Given the rapid sterilizing effect of rifampicin, the isolation of infectious TB patients from other hospital patients and from the community was no longer considered important. As a result, TB isolation wards were discontinued, and measures such as cough hygiene and wearing of surgical masks by infectious patients were no longer encouraged.
Respiratory Protective Equipment Administrative measures Administrative controls are the first and most important level of the hierarchy. These are management measures that are intended to reduce the risk or exposure to persons with infectious TB.
These control measures consist of the following activities: Assigning someone the responsibility for TB infection control in the health care setting; Conducting a TB risk assessment of the setting; Developing and implementing a written TB infection-control plan; Ensuring the availability of recommended laboratory processing, testing, and reporting of results; Implementing effective work practices for managing patients who may have TB disease; Ensuring proper cleaning, sterilization, or disinfection of equipment that might be contaminated e.
Environmental controls The second level of the hierarchy is the use of environmental controls to prevent the spread and reduce the concentration of infectious droplet nuclei. This includes two types of environmental control. Primary environmental controls consist of controlling the source of infection by using local exhaust ventilation e.
Secondary environmental controls consist of controlling the airflow to prevent contamination of air in areas adjacent to the source airborne infection isolation AII rooms; and cleaning the air by using high efficiency particulate air HEPA filtration, or ultraviolet germicidal irradiation.
Respiratory Protective Equipment The third level of the hierarchy is the use of respiratory-protection control. It consists of the use of personal protective equipment in situations that pose a high risk of exposure to TB disease. Use of respiratory protection equipment can further reduce risk for exposure of health care workers to infectious droplet nuclei that have been expelled into the air from a patient with infectious TB disease.
The following measures can be taken to reduce the risk for exposure: Implementing a respiratory protection program; Training health care workers on respiratory protection; and Educating patients on respiratory hygiene and the importance of cough etiquette procedures.Published: Thu, 25 Jan To address the problem of Tuberculosis (TB) within East London.
