Slide 4

MEPS History

• 1977 National Medical Care Expenditure Survey

• 1996 Medical Expenditure Panel Survey

Slide 5

MEPS-HC Purpose & Uses

• Estimates and tracks annual health care use, expenditures and insurance coverage.
• Provides estimates of expenditures and sources of payment by selected demographic variables.
• Used for policy-related and behavioral research on the determinants of health care use, spending, and insurance coverage.
• Used in microsimulation models to analyze alternative health care delivery proposals.

Slide 6

MEPS Survey Components

• MEPS-HC—Household Component
• MEPS-MPC—Medical Provider Component
• MEPS-IC—Insurance Component

Slide 7

MEPS-HC Survey Design

• Sub-sample of respondents from the previous year's National Health Interview Survey (NHIS).
• Representative of the civilian non-institutionalized population of the US.
• Five in-person interviews over 2 1/2 year period using Computer Assisted Personal Interview (CAPI).
• Interviews average 90 minutes with a range of one to four hours.

Slide 8

Oversampling in MEPS Panels 7-14 (2002-2009)

• Carryover from NHIS:
  • Blacks
  • Hispanics
  • Asians (panels 12-14 after 2006 NHIS redesign)
• Additional MEPS Oversampling:
  • Asians
  • Low income (panels 7-13)
  • Blacks (panels 9-11, 13-14)
  • Hispanics (panels 13-14)

Slide 9

MEPS Panel Design: Data Reference Periods

Image: A graph showing Panel 10, Panel 11, Panel 12, and Panel 13 is shown. The vertical axis shows the years 2006, 2007, and 2008. Each year is broken down by Q1, Q2, Q3, and Q4. The sample size for 2006 is 32,577, 2007 is 29,370, and 2008 is 31, 262.

N is equal to the number of people with a positive person weight on the file.

Slide 28

Medical Expenditure Panel Survey

Medical Conditions Data

Slide 29

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

• 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

• 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
• Conditions associated with Prescribed Medicine purchases:
  • What health problem is (Medicine) prescribed for?
    Probe: Any other health problems?

Slide 32

Disability Days Condition Questions

• Missed school or work:
  • What are the health problems that caused (Person) to miss work/school on those days? Probe: Any other health problems?
• Bed days:
  • What are the health problems that caused (Person) to spend half day or more in bed on those days? Probe: Any other health problems?

Slide 33

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

• 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

• 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

• 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

• 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)

• 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

• 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

• 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

• 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

• 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)

• Heart disease
• Heart attack
• Angina
• High cholesterol
• Cancer
• Stroke
• High blood pressure
• Diabetes
• Asthma
• Arthritis/Joint pain
• Emphysema
• Chronic bronchitis
• Attention deficit disorder

Slide 44

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.

Slide 45

Medical Expenditure Panel Survey

Health Care Utilization And Expenditures Data

Slide 46

Health Care Utilization

  • Home Health Care (HH)
  • Other Medical Expenses (OM)

Slide 47

Health Care Expenditures

• Collected at the event level.
• Represent payments to providers of the health care.
• Payments are reported by source (e.g., out-of-pocket, private insurance, public program).
• Total expenditure is sum of payments across all sources of payment.

Slide 48

Source of Payment Categories in CAPI

• Self or family
• Medicare
• Medicaid/SCHIP

  • Results in no missing values.
