Summary
Brief summary (as posted)
The objective is to measure the adjusted association between preoperative anemia and total hospital costs. We hypothesize that patients with anemia before surgery will have higher hospitalization costs than people without anemia.

- Total Hospital Costs
- timeFrame
- Hospital admission to date of discharge from hospital, or 365 days after admission, whichever came first
- description
- Direct and indirect costs accrued during the index hospitalization. Costs were measured using standard and validated algorithms, standardized to 2016 CAD. This method accounts for a patient's resource intensity weight, their case mix group, as well as fixed patient costs (e.g., medications, investigations) and indirect costs to the hospital based on patient's location of care (intensive care unit versus ward) and length of stay.
