Predicting outcomes of burns

Article Abstract:

Survival in burn patients is so high it is difficult to determine which factors predict mortality. A 1998 study found that age greater than 60, inhalation injury and burns over more than 40% of the body were associated with increased mortality. However, in the study of 1,665 burn patients, only 1.3% fell into that category. About 80% of the patients had little risk of dying. This is in contrast to the situation in the 1940's, when over half of patients with burns over 40% of their bodies died. This is due to the great advances made in the treatment of burns, including the establishment of burn centers.

Gains in life expectancy from medical interventions - standardizing data on outcomes

Article Abstract:

Gains in life expectancy from a specific medical intervention can be estimated as large or small by comparing it to gains from other interventions. Researchers categorized gains in life expectancy reported in 83 articles according to patient population and disease. Preventive interventions resulted in gains from less than one month to one year if the person had an average risk of getting the disease but gains up to five years or more if they had a high risk of getting the disease. Treatments for existing disease resulted in gains ranging from several months up to nine years.

Comparison of transmyocardial revascularization with medical therapy in patients with refractory angina

Article Abstract:

Transmyocardial revascularization may relieve symptoms in some patients with angina that cannot be treated by other means. In this procedure, a laser is used to create channels in the heart muscle to improve blood flow. Researchers randomly assigned 275 patients with angina to receive this procedure plus drug treatment or drug treatment alone. One-third of those who received only drugs improved compared to 76% of those who received the procedure. However, thallium scans revealed no differences in blood flow between the two groups.
