Description
This phenotype returns the last known date that the patient was considered alive according to MPOG data. It is used to help determine the date of death and Mortality data
Limitation
Data quality is limited to individual site documentation accuracy, completeness, and variable mapping, which is performed by each site, independently.
MPOG, as the coordinating center, reviews data quality at each data upload and monthly via Data Diagnostics and Case Validation tools. This review,
while thorough, may not contain all data elements relevant to this phenotype and thus should be carefully reviewed by the user.

Logic
The latest date of the following criteria is returned as the 'Last Known Alive' date:
- The latest 'Anesthesia Start'.
- The latest medication dose.
- The latest lab observation date.
- The date of death recorded by institution.
Other Details:
- Observation date is used as it reflects the date that the lab was drawn and may be different from the date that the lab was resulted.
- This phenotype evaluates each patient ID at each institution.
- This phenotype omits dates where the patient is recorded as an ASA 6 or 01990 concept is specified (A declared brain-dead patient whose organs are being removed for donor purposes).
- It will only return patients with a last known alive date. If there is no last known alive date by this logic (no reported anes start, medications, or labs for this patient), this collation will not return the patient.
