The Filter to Include Healthcare Encounters field is an optional parameter that enables you to subset the findings data set before analysis. Only those rows that meet all of the conditions specified in the field are included in the analysis.
It is necessary to use quotation marks when filtering data using values of a character variable (HOTERM = “HOSPITAL”, for example), but no quotation marks are required for filtering by values of a numeric variables.
The syntax of this filter expression follows the syntax of SAS WHERE statements. For more information about using filter fields, see The SAS WHERE Expression.
