Persons who use tobacco or alcohol 40,41illegal drugs, including injection drugs and crack cocaine 42—47might also be at increased risk for infection and disease.
However, because of multiple other potential risk factors that commonly occur among such persons, use of these substances has been difficult to identify as separate risk factors. Health-care settings should be particularly aware of the need for preventing transmission of M. Persons infected with HIV who are already severely immunocompromised and who become newly infected with M.
Because the risk for disease is particularly high among HIV-infected persons with M. Vaccination with BCG probably does not affect the risk for infection after exposure, but it might decrease the risk for progression from infection with M.
Exposure to TB in small, enclosed spaces. Inadequate local or general ventilation that results in insufficient dilution or removal of infectious droplet nuclei.
Recirculation of air containing infectious droplet nuclei. Inadequate cleaning and disinfection of medical equipment. Improper procedures for handling specimens. The magnitude of the risk varies by setting, occupational group, prevalence of TB in the community, patient population, and effectiveness of TB infection-control measures.
Health-care—associated transmission of M. Factors contributing to these outbreaks included delayed diagnosis of TB disease, delayed initiation and inadequate airborne precautions, lapses in AII practices and precautions for cough-inducing and aerosol-generating procedures, and lack of adequate respiratory protection.
Multiple studies suggest that the decline in health-care—associated transmission observed in specific institutions is associated with the rigorous implementation of infection-control measures 11,12,18—20,23,95— Because various interventions were implemented simultaneously, the effectiveness of each intervention could not be determined.
After the release of the CDC infection-control guidelines, increased implementation of recommended infection-control measures occurred and was documented in multiple national surveys 13,15,98, A survey of New York City hospitals with high caseloads of TB disease indicated 1 a decrease in the time that patients with TB disease spent in EDs before being transferred to a hospital room, 2 an increase in the proportion of patients initially placed in AII rooms, 3 an increase in the proportion of patients started on recommended antituberculosis treatment and reported to the local or state health department, and 4 an increase in the use of recommended respiratory protection and environmental controls Reports of increased implementation of recommended TB infection controls combined with decreased reports of outbreaks of TB disease in health-care settings suggest that the recommended controls are effective in reducing and preventing health-care—associated transmission of M.
Less information is available regarding the implementation of CDC-recommended TB infection-control measures in settings other than hospitals. One study identified major barriers to implementation that contribute to the costs of a TST program in health departments and hospitals, including personnel costs, HCWs' time off from work for TST administration and reading, and training and education of HCWs Outbreaks have occurred in outpatient settings i.
CDC-recommended TB infection-control measures are implemented in correctional facilities, and certain variations might relate to resources, expertise, and oversight — In the United States, the problem of MDR TB, which was amplified by health-care—associated transmission, has been substantially reduced by the use of standardized antituberculosis treatment regimens in the initial phase of therapy, rapid drug-susceptibility testing, directly observed therapy DOTand improved infection-control practices 1.
DOT is an adherence-enhancing strategy in which an HCW or other specially trained health professional watches a patient swallow each dose of medication and records the dates that the administration was observed. All health-care settings need a TB infection-control program designed to ensure prompt detection, airborne precautions, and treatment of persons who have suspected or confirmed TB disease or prompt referral of persons who have suspected TB disease for settings in which persons with TB disease are not expected to be encountered.Play a game of Kahoot!
