Specification |
STEP 1: Enrolled on the last day of DQ report month Define the eligible population from segment ENROLLMENT-TIME-SPAN-ELG00021 by keeping active records that satisfy the following criteria: 1. ENROLLMENT-EFF-DATE <= last day of the DQ report month 2. ENROLLMENT-END-DATE >= last day of the DQ report month OR missing 3. MSIS-IDENTIFICATION-NUM is not missing STEP 2: Eligible contact information on the last day of DQ report month Using the MSIS IDs that meet the criteria from STEP 1, join to segment ELIGIBLE_CONTACT_INFORMATION ELG00004 by keeping records that satisfy the following criteria: 1a. ELIGIBLE-ADDR-EFF-DATE <= last day of the DQ report month 2a. ELIGIBLE-ADDR-END-DATE >= last day of the DQ report month OR missing OR 1b. ELIGIBLE-ADDR-EFF-DATE is missing 2b. ELIGIBLE-ADDR-END-DATE is missing STEP 3: Non-missing county code for primary address Of the MSIS IDs that meet the criteria from STEP 2, further refine the population by keeping records with: 1. ELIGIBLE-COUNTY-CODE non-missing 2. ELIGIBLE_ADDRESS_TYPE = "01" STEP 4: Percent eligible county code for the current month 1. For each distinct value of county code, set the number of unique MSIS IDs as Numerator_Count_By_Value. 2. Set the total number of unique MSIS IDs across all valid values of county code as Denominator_Count. Note that Denominator_Count should also equal to the count of MSIS IDs from STEP 3. 3. For each distinct value of county code, calculate Percent_Current_Month as the ratio of Numerator_Count_By_Value over Denominator_Count. STEP 5: Percent eligible county code for the previous month Repeat STEP 1 through STEP 4 for the previous month. For each distinct value of county code, set the percent of county code for the previous month as Percent_Prior_Month_1. STEP 6: Calculate change between months For each frequency percent, calculate Frequency_Change as the absolute value of (Percent_Current_Month – Percent_Prior_Month_1) / 2. Note that Frequency_Change is a vector of frequencies. STEP 7: Calculate index of dissimilarity Calculate the index of dissimilarity by summing Frequency_Change across all frequencies and dividing by 100 |
