The calculation for the Count of Expected 30-Day Readmissions is incorrect in Volume 2. IDSS currently calculates this field by using the formula "Count of Expected 30-Day Readmissions" = "Expected Readmission Rate" * "Count of Index Stays".
Please provide data for the Expected Readmission Rate and the Count of Index Stays and IDSS will use these values to generate the correct calculation.
