Obstetrics, 3 days, and Pediatrics, 5 days (2+3).

AVERAGE LENGTH OF STAY Since totals alone do not give much useful information, the most common use of discharge days is calculating the average length of stay. An average is generally much more easily interpreted-both for statistical purposes and for comparisons. The average length of stay is a representation of the average duration of hospitalization for the group under consideration. Note: Average length of stay calculations do not combine A&C and NB data for the same reason that average daily census and occupancy percentages were computed on two unique populations. 1. Adults and Children (A&C) When a question asks for average length of stay, it is assumed that the A&C average is to be determined. As mentioned above, would be rare to want to combine A&C and newborns in the same average length of stay.

Data indicate a hospital had a total of 200 discharge during March with a total of 3.500 discharge days.
