Abstract
This study utilised a large audit database from a trauma unit, to model the length
of stay of the patient in the unit, i.e. bed occupancy, for all those with upper and
lower limb fractures. For this purpose, we applied two methodologies: a decision
tree approach utilising Quinlan's See5 machine learning environment was
compared with a modification of Cox's regression, a statistical approach and the
two systems evaluated for classification accuracy. Data from 747 lower limb and
487 upper limb cases were analysed, with the model being extracted from key
parameters, which were retrieved from the original database. We also used
information from the medical personnel involved and indicators of significance
from preliminary studies. Exactly the same model and para
