Chest X-rays May Help Predict H1N1 Risk

TEL AVIV, Israel, March 26 (UPI) — Israeli physicians suggest chest X-rays may help identify high-risk H1N1 patients who have been hospitalized.

The lead author of a study, Dr.Galit Aviram of Tel Aviv Sourasky Medical Center, says although a normal chest X-ray did not exclude the possibility of an adverse flu outcome, the doctors found abnormal results could help better identify patients requiring close monitoring.

“Abnormal findings in the periphery of both lungs and in multiple zones of the lungs were associated with poor clinical outcomes,” Aviram says in a statement.

Aviram and colleagues took chest X-rays of 97 consecutive patients with laboratory-confirmed H1N1 diagnosis admitted between May and September 2009 to Sourasky’s emergency department — 53 men and 44 women with a mean age of 40.4.

When the chest X-rays were correlated with outcomes, the doctors found abnormal X-ray findings for 39 of the patients — five died or needed mechanical ventilation.

In the group of 58 patients with normal chest X-ray findings, two patients experienced adverse outcomes, the study says.
