SEER-CAHPS Instructions for Using SEER*Stat Flag

Step 1: Create a New Frequency Session

  • Start SEER*Stat.
  • From the File menu select New > Frequency Session or use the hashtag on the toolbar.

  • SEER*Stat uses two modes of execution. If SEER*Stat is in client-server mode you will be prompted for a username and password each time you use SEER*Stat. See Local vs. Client-Server ModeExternal Web Site Policy in the SEER*Stat help system to learn more.
  • Each SEER*Stat session type is described in detail in the help system. Look for "Frequency Session", "Rate Session", "Survival Session", "Limited-Duration Prevalence Session", "MP-SIR Session", and "Case Listing Session" in the help systemExternal Web Site Policy.

Step 2: Select a Database (Data Tab)

  • On the Data Tab select the following Database:
    Incidence- SEER 18 Regs + Hurricane Katrina Impacted Louisiana Cases Custom Data (with CAHPS variables), Nov 2013 Sub (1973-2011 varying).

Step 3: Choose the Statistics to Display (Statistic Tab)

  • Move to the Statistic Tab.
  • In the Statistic box, select Frequencies.
  • In the Percentages box, select Column.

  • Percentages can only be selected if Frequencies are chosen.
  • It can be difficult to remember if you want to use Column Percentages or Row Percentages. Here is a tip that may help: selecting Column Percentages will generate percentages of the row variables (column percentages sum to 100 in the column, row percentages sum to 100 in the row). As a rule of thumb, put your percentages in one dimension of the table and the variable in the other.
  • Percentages can only be calculated on variables with unique groupings, that is, the values in the groupings cannot overlap. For example, to calculate the percent of cases for males versus females, you would have to create a variable that does not include the "Males and Females" combined grouping.
  • Parameters are only enabled and can be selected if Trends are chosen as the statistic.

Step 4: Defining the Analysis Cohort (Selection Tab)

  • Move to the Selection Tab.
  • Before you continue, please take time to consider the following:
    • There are two basic mechanisms for making selections: adding selection statements and checking standard options. Selection statements reduce the number of records included in an analysis based on specific variables. Selection options are checkboxes that implement commonly used selection statements. If no selections are made then your analysis cohort will include every case in the database (all cases in the 18 SEER registries for 1973-2011). In the Select Only box at the top of the Selection Tab, uncheck the "Malignant Behavior" option and make sure the "Known Age" and "Cases in Research Database" options are checked. Also, you generally want to check the option to "Select only the first matching record for each person."
  • Use the edit button to open the Case Selection window.
  • Using the controls at the top of the Case Selection window, you will create a selection statement. The variables are listed in categories in the Variable box on the top left of the screen.
  • In the Variable box, use the "+" to expand the "Site and Morphology" category.
  • Select "Site recode ICD-O-3/WHO 2008".
  • Moving to the center of the window, check to see that "is = to" is selected as the Operator.
  • Scroll through the items in the Values box until you find and select the cancer site(s) you are interested in.
  • You can choose to include other selection variables, for example, age at diagnosis, sex, race, stage, and others.
  • Use the OK button to close the Case Selection window.

  • Advanced features of the Selection Tab, including "Select Only the First Matching Record for Each Person" and full "Person Selection" are described in the Frequency Selection TabExternal Web Site Policy section of the SEER*Stat help system.
  • Full Boolean logic can be used to create complex selection statements as described in the Selection Statement DialogExternal Web Site Policy section of the help system.

Step 5: Set Table Variables (Table Tab)

  • Move to the Table Tab.
  • To successfully use SEER*Stat, you must understand the purpose of the Selection Tab versus the Table Tab. These are often confused. Before you continue, please consider the following:
    • The Table Tab is used to choose the variables to be displayed and does not affect the number of records analyzed in any way.
    • The Selection Tab is used to reduce the number of records included in an analysis based on specific variables. We recommend that you use the Selection Tab to select which cancer site(s), stage(s), and other sociodemographic/clinical information to narrow your frequency run.
  • The variables are listed in categories in the Available Variables box at the bottom of the screen.
  • Use the "+" to expand the "SEER- CAHPS" category.
  • Select any of the indicators you see here:
    • CAHPS Indicator:
      • No match = Patient not in the SEER-CAHPS file.
      • Match = Patient in the SEER-CAHPS file.
    • CAHPS – Number of Medicare Advantage surveys
    • CAHPS – Number of Fee for Service surveys
    • CAHPS – Number of Medicare Advantage surveys - Prior to DX
    • CAHPS – Number of Fee for Service surveys- Prior to DX
    • CAHPS – Number of Medicare Advantage surveys - Post DX
    • CAHPS – Number of Fee for Service surveys- Post DX
  • Click Row on the right hand side of the screen.
  • At this time, the CAHPS indicator variable you chose should be listed as a row variable in the Display Variables box at the top of the window.

Step 6: Specify a Title (Output Tab)

  • Move to the Output Tab.
  • Enter the following title:
    "Number of cases in SEER for SEER-CAHPS analysis"

Step 7: Execute SEER*Stat

  • Use the lightning or select Execute from the Session menu to execute the session. (Execute Offline is a 3rd option that is described below in the Learn More section).
  • A dialog will display the progress of the job. When the job completes a new window will open containing the output table or matrix. Results shown in the SEER*Stat matrix window cannot be edited. However, you do have the ability to print the matrix, export the results to a text file, and copy-and-paste data into other applications. The Results MatrixExternal Web Site Policy section of the help system contains more information about the SEER*Stat matrix and its features.
  • Notice that only the first line of the title (as entered on the Output Tab) appears on the title bar. The entire title will appear on printouts.

Learn More...

  • If you are running SEER*Stat in client-server mode you will also have the option to Execute Offline. This feature is intended for jobs that take several minutes or longer to complete. SEER*Stat automatically sends an e-mail message to you as soon as the execution is complete. The e-mail message includes a link to the location of the results matrix.

Step 8: Save the Matrix

  • You may want to widen the column of labels so that all text is shown. Put your cursor over the column's right divider until the cursor becomes resize. Click and drag to size.
  • Use the Save As command on the File menu to save the matrix. SEER*Stat will assign the "sfm" extension to indicate that this is a "SEER*Stat Frequency Matrix" file.

Step 9: Print the Matrix and Check the Results

  • Use the Print command on the File menu to print the matrix. You will notice that the session information is printed along with the results matrix. The session information serves as documentation for the table. Notice that the name of the matrix file is printed at the top of each page. More information regarding the matrix optionsExternal Web Site Policy and print optionsExternal Web Site Policy are included in the SEER*Stat help system.
