About this study

The purpose of the study is to identify the patients at high risk of developing Acute Lung Injury (ALI) at the time of hospital admission, and before intensive care unit admission.

Aim 1- To validate the prediction model (Lung Injury Prediction Score) in a population based sample of hospitalized patients.

Aim 2- To determine the significance of health-care related ALI risk modifiers in a population based sample.

Aim 3- To compare the short and long term outcomes between patients at high risk who do, and do not develop ALI.
