MEPS Condition Roster

  • One roster per person.
  • Cumulates medical conditions reported across MEPS interviews.
  • Interviewer records verbatim responses to questions in the following 3 sections:
    • Condition Enumeration
    • Medical Events
    • Disability

Slide 30

Condition Enumeration Question

Condition Enumeration Question

  • We're interested in learning about health problems that may have bothered (Person) {since (Start Date)/between (Start Date) and (End Date)}.
    • Health problems include physical conditions, accidents, or injuries that affect any part of the body as well as mental or emotional health conditions, such as feeling sad, blue, or anxious about something.

Slide 31

Medical Events Condition Questions

Medical Events Condition Questions

  • What conditions were discovered or led (Person) to make this visit? Probe: Any other condition? If Condition is Already Listed, Ask: Is this the same (Name of Condition) that we have already talked about before?
    • Types of visits
      • Inpatient
      • Outpatient
      • Emergency Room
      • Office Based
      • Home Health

Slide 33

Reporting and Recording Conditions

Reporting and Recording Conditions

  • Respondents may report having the same condition more than once:
    • Interviewer probes whether occurrence of condition already reported.
    • Each unique episode of a condition recorded only once
      • Person may have multiple colds in year.
      • Each cold has separate record.

Slide 34

Accidents and Injury Questions

Accidents and Injury Questions

  • Following items asked if relevant to reported condition:
    • Date of accident
    • Place (work, home, school, etc.)
    • Cause (gun, vehicle, fall, fire, etc.)
    • Whether or not the person has recovered from the injury

Slide 35

Medical Conditions File Structure

Medical Conditions File Structure

  • Each record represents unique condition or procedure for a person.
  • Persons may be represented on file once, several times or not at all.
  • Can be linked to person and event files for analysis.

Slide 36

Condition Coding and Editing

Condition Coding and Editing

  • Fully specified ICD-9 CM codes (up to 5 digits).
  • ICD-9 condition codes collapsed to 3 digits to maintain confidentiality.
  • Approximately 10% of condition codes are collapsed further by combining 2 or more 3-digit codes.

Slide 37

Procedure Coding and Editing

Procedure Coding and Editing

  • Only obtained from Medical Events Questions.
  • Fully specified ICD-9 CM codes (up to 4 digits):
    • Collapsed to 2-digit codes .
    • Approximately 3% collapsed further by combining 2 or more 2-digit codes.

Slide 38

Clinical Classification Codes (CCC)

Clinical Classification Codes (CCC)

  • ICD-9 codes aggregated into broad clinically meaningful categories.
  • Edited to preserve confidentiality.
  • Crosswalk included in documentation.
  • Formerly Clinical Classification for Health Policy Research (CCHPR).

Slide 39

Condition-Event Link Files

Condition-Event Link Files

  • Used to link conditions to:
    • Persons on person files
      • All reported conditions or just those associated with events
    • Events on event files:
      • Most conditions associated with events already included on event files
  • Separate link file for prescribed medicines.

Slide 40

National Estimates of Conditions

National Estimates of Conditions

  • Most appropriate to estimate "treated prevalence"
    • MEPS Web site summary data tables on Expenditures by Medical Condition .
  • Condition more likely to be underreported if:
    • Respondent/person not aware.
    • Not salient or bothersome.
    • No medical care received.

Slide 41

Condition Data Limitations/Caveats

Condition Data Limitations/Caveats

  • Household-reported:
    • One respondent usually providing information for all household members.
  • Many recorded text strings not easily classifiable into ICD-9 codes.
  • Limited information on procedures.
  • Not suitable for prevalence estimates.
  • More salient conditions tend to be better reported.

Slide 42

Priority Conditions Section

Priority Conditions Section

  • Separate section of questionnaire.
  • Series of questions asking if "ever" had condition:
    • "yes/no" responses, no ICD9 coding .
    • Responses not directly linked to conditions roster.
  • Factors used in determining priority conditions:
    • Prevalence.
    • Expenditures.
    • Policy relevance.

Slide 43

Priority Conditions List (Panel 12 and beyond)

Priority Conditions List (Panel 12 and beyond)

Slide 44

Priority Condition Section Revisions

Priority Condition Section Revisions

  • Revised section in Panel 12:
    • Priority Conditions Enumeration (PE) section replaced PC section in prior panels.
  • Primary differences between PE and PC:
    • Questions asked all rounds rather than 3/5 only.
    • PE section substantially earlier in CAPI.
    • Follow-up question on cancer remission added.
    • Age of diagnosis collected for more conditions.
  • Revisions may increase reporting of conditions and associated medical events.
