Brief Summary

Over 300 million surgeries are performed globally every year. Complications after surgery - infections, cardiovascular conditions, postoperative pulmonary complications and renal impairment - affect survival and quality of life.

Age and co-morbidity are unmodifiable factors, contributing to increased risk of these perioperative complications. However, a modifiable risk factor is physical activity. This study aims to test if self reported physical activity is associated to lower risk of perioperative morbidity and mortality.

Conditions

• General Surgery
• Perioperative Complication
• Perioperative Medicine
• Physical Inactivity

Primary Outcome Measures

• Mortality (Mortality will be recorded at 30, 60, 90 and 365 days after index surgery)
  Death within the time frames described below
• DAH30 (Days At Home alive at 30 days) (30, 90 and 365 days after index surgery,)
  DAH30: Patients who are hospitalized for 14 days postoperatively but are alive on day 30 will have DAH30=16. Patients who are hospitalized for five days, then discharged, but return after 10 days for an additional 11-day stay, will have DAH30=14. Anyone who dies within 30 days will have DAH30=0. This outcome measure is validated in several studies and has a significant advantage in that it correlates well with complications, even better than length of stay (LOS). We will further record DAH90 and DAH365, calculated as described above.
