A multicenter study examines how the 6-minute walk test (6MWT) can enhance risk assessment for patients undergoing major non-cardiac surgery.

• The study includes 1,672 patients aged 40+, measuring their walk test results alongside other fitness indicators.
• It aims to clarify if the 6MWT predicts 30-day complications better than standard clinical assessments.

Effective preoperative fitness evaluation could guide surgical planning and patient selection more precisely.

• Primary outcomes include death or major complications within 30 days post-surgery.
