======  OHDSI Perioperative Prediction: Development and Validation of Prognostic Prediction models for Post-Operative Outcomes of Interest ======

<WRAP box justify round>

**Objective:** //To create a set of patient level prediction models for patients undergoing non-maternal, non-cardiac surgeries, examining a set of post-operative outcomes of interest//

**Rationale:** //Surgical procedures are frequently performed in large health care systems, with over 15 million invasive surgeries per year in the United States (1).  Serious complication rates arise in this population (2).  In an effort to counsel patients and reduce their cardiac and non-cardiac surgical risks, the field of perioperative medicine often looks to multivariate prediction models across outcomes of interest.   Point of care deployments of these often favour parsimonious models (e.g. the 6 point Revised Cardiac Risk Index (3)).  These could potentially be outperformed or complemented by machine learning approaches to prediction that utilize a comprehensive representation of the patient record as a feature source, especially as point of care application becomes automated in the era of the electronic medical record.
