Summary

This study looked at how often patients develop confusion after surgery (postoperative delirium) and what factors increase the risk. Researchers tracked over 2,400 adults in Spanish hospitals who had surgery requiring an overnight stay. The goal is to use this information to create better prevention plans and reduce the impact of delirium on recovery.
