TL;DR: Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries and should also address the need for safe perioperative care.

TL;DR: Subjective assessment of functional capacity should not be used for preoperative risk evaluation, and Clinicians should instead consider a measure such as DASI for cardiac risk assessment.

TL;DR: The authors' four recommended outcome measures include a new definition of postoperative pulmonary complications, incorporating an assessment of severity, which will meet the needs of most clinical effectiveness trials of treatments to improve post operative pulmonary outcomes.

TL;DR: World Health Organization Disability Assessment Schedule 2.0 is a clinically acceptable, valid, reliable, and responsive instrument for measuring postoperative disability in a diverse surgical population and its use as an endpoint in future perioperative studies can provide outcome data that are meaningful to clinicians and patients alike.

TL;DR: DAH30 has construct validity and is a readily obtainable generic patient-centred outcome measure that is a pragmatic outcome measure for perioperative clinical trials.
