Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To derive and internally validate a multivariable prediction model that uses only routinely available preoperative clinical variables, measured before requesting a transthoracic echocardiogram, to estimate the probability that the echocardiogram will lead to an actionable change in perioperative cardiac management in adults aged 60 years and above undergoing elective non-cardiac surgeryTimepoint: The day before the surgery date | — |
Secondary
| Measure | Time frame |
|---|---|
| Perioperative MACE (MI, cardiac arrest, new arrhythmia requiring treatment, acute heart failure, stroke) Timepoint: 24 hours, 7 day & 30 day;Surgical delay (days from echo order to surgery date) Timepoint: On the day of surgery;30-day mortalityTimepoint: 30 days following surgery | — |
