Epidemiology of drug-resistant tuberculosis in Texas

Article Abstract:

In Texas more than 22,000 tuberculosis cases were reported, 1987-96, giving an average annual incidence of 12.5 cases per 100,000 population. Highest rates were found in counties along the Mexican border and in the northwestern part of the state. Resistace to at least one of the five first-line antituberculosis agents was found in 9% of the cases. Almost 5% were resistant to isoniazid, alone or in combination with other antibiotics, while 2.3% were resistant to rifampin, and 1.3% were resistant to both. Factors associated with multi-drug resistant tuberculosis included a history of tuberculosis infection, being born outside the US, being younger than 20 years of age, and living in a Mexican border county. Those with HIV infection were less likely to have isoniazid resistance and more likely to have rifampin resistance than others.

Accuracy of ICD-9-CM codes in detecting community-acquired pneumococcal pneumonia for incidence and vaccine efficacy studies

Article Abstract:

The coding of pneumococcal pneumonia according to ICD-9-CM standards may not be always accurate. Researchers found the coding of 240 hospitalized patients with confirmed pneumococcal pneumonia diverse, depending on the case definition. More than 58% of the most common classification was correctly used. The review of medical charts and careful coding should minimize diagnostic errors.
