What are major contributing factors to the development of MDR-TB?

MLRA identified six significant independent risk factors for the occurrence of MDR-TB as follows: monthly income of the family (Odds ratio (OR) = 3.71; 95% Confidence Interval (CI) = 1.22–11.28), defaulting from treatment (OR = 3.33; 95% CI = 1.14–9.09), stigma associated with TB (OR = 2.97; 95% CI = 1.18–7.45).

How can multidrug resistance be prevented?

The groups of preventive measures recommended for control of multidrug-resistant organisms—administrative action, education, surveillance, use of active surveillance cultures, analysis of and provision of feedback to caregivers about surveillance data, use of personal protective equipment, standard precautions ( …

FASTPlaque-Response is a phage amplification-based test, and has been developed for direct use on sputum specimens. Drug resistance is diagnosed when M tuberculosis is detected in samples that contain the drug (ie, RIF).

What is the first action to take to prevent the spread of tuberculosis?

good ventilation: as TB can remain suspended in the air for several hours with no ventilation. natural light: UV light kills off TB bacteria. good hygiene: covering the mouth and nose when coughing or sneezing reduces the spread of TB bacteria.

What is the most important risk factor for MDR-TB?

A review of the published literature strongly suggest that the most powerful predictor for the presence of MDR-TB is a history of TB treatment. Many new cases of MDR-TB are created by physician’s errors related to drugs regimen, dosing interval and duration of treatment.

Who is at risk for MDR-TB?

MDR-TB cases were more likely to be foreign born (odds ratio (OR) 2.46; 95% CI 1.86 to 3.24), younger than 65 years (OR 2.53; 95% CI 1.74 to 4.83), male (OR 1.38; 95% CI 1.16 to 1.65), and HIV positive (OR 3.52; 95% CI 2.48 to 5.01). Conclusions: Previous treatment was the strongest determinant of MDR-TB in Europe.
