ClinConnect Summary

This clinical trial is studying how well we can measure a person’s fitness before surgery by comparing two methods: one that involves a simple exercise test to measure oxygen consumption (VO2) and another that uses a questionnaire about physical activity. The goal is to see if the questionnaire can reliably estimate a patient’s fitness level, which is important for planning safe surgeries.

To join this study, participants need to be at least 18 years old, able to speak English, and can walk with or without help. They should be scheduled for a preoperative assessment and have a specific score on a fitness questionnaire. However, people with certain health issues, like recent heart problems or severe high blood pressure, can't participate. If you join, you can expect to do a short exercise test and answer some questions about your physical activity. This study is an important step in improving how we assess patients' fitness before surgery, which can help ensure safer surgical experiences.
