Limitation

none

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

As developed by the American Society of Anesthesiologists (ASA), the ASA Physical Status Classification is a six-category system for assessing health and fitness of patients prior to anesthesia/surgery1.

This collation uses the Emergency Status collation value and maps it to a “Yes” (1) or a “No” (0) response. Yes (1) indicates that the case was listed as Emergency Status, a No (0) indicates it was not. If the value is invalid (does not fit emergent documentation) it returns “Invalid” (-998). If there are multiple valid documented values a “Conflicting” (-997) is returned. Missing documentation is returned “Missing” (-999). A NULL may be returned if the note is available but has yet to be mapped.

This collation can accompany the ASA Class (cleaned) collation to return a numerical ASA Classification and the traditional alpha “E” notation in the form of this collation’s Yes/No (1/0) response.
