Is the word confusas the same in Brazilian and European Portuguese?

Yes

The meaning, spelling, and grammar of "confusas" are identical in both Brazilian and European Portuguese. The only difference lies in pronunciation:

• Brazilian Portuguese: The vowels are typically more open and clearly articulated. The final "s" is usually pronounced as a dental "s" (similar to the "s" in the English word "bus").
• European Portuguese: The vowels are more "closed" or reduced (the sound is more muffled). Crucially, the final "s" undergoes palatalization, meaning it is pronounced as a "sh" sound (similar to the "sh" in "shoe").
