# Filter to Choose Healthcare Encounters for RBM

The Filter to Include Healthcare Encounters for RBM field enables you to filter rows from the HO data set to choose the appropriate records to subset to health-care encounters of interest. Risk indicators are then calculated using this subset of health-care encounters only.

Note: 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 variable.

You can enter one or more statements (joined by AND or OR) in this field.

The syntax of this filter expression follows the syntax of SAS WHERE statements. For more information about this syntax, see The SAS WHERE Expression.
