You cannot calculate the geometric mean from the arithmetic mean. Intensive care unit ICU length of stay LOS and hospital LOS are common indices used to compare performance of hospitals and are yardsticks used in efforts to contain costs yet there is no standardized method of quantitating this outcome variable. The goal of this quality improvement project was to reduce the length of hospitalization to improve patient satisfaction and meet the geometric mean length of stay GMLOS.
Here are some practical steps that the hospital can take to reduce the length of stay index.
