MEPS Survey Components

MEPS-HC -- Household Component

MEPS-MPC -- Medical Provider Component

MEPS-IC -- Insurance Component

Page 7: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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 ½ year period using Computer Assisted Personal Interview (CAPI)

Interviews average 90 minutes with a range of one to four hours

Page 8: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Oversampling in MEPS Panels 7-15 (2002-2010)

Carryover from NHIS– Blacks– Hispanics– Asians (panels 12-15 after 2006 NHIS redesign)

Additional MEPS Oversampling– Asians – Low income (panels 7-13)– Blacks (panels 9-11, 13-15)– Hispanics (panels 13-15)

MEPS-HC Supplemental Paper Questionnaires

Diabetes Care Survey (DCS)• Given once a year to each person identified as

having diabetes• Includes questions about diabetes related tests

and managing diabetes

Adult Self-Administered Questionnaire (SAQ)• Given once a year to each adult 18 years old and

older• Focuses on self-reported information such as

opinions about health care issues and quality of care measures, assessment of own health, and height /weight.

Page 14: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

MEPS-HC Caveats and Limitations

Sample size limitations preclude some analyses

Typically, one respondent provides data for the entire household

Household respondents may not be able to report accurately certain types of information– type of health plan– detailed event information– diagnoses

MEDICAL CONDITIONS DATA

Page 16: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Medical Conditions File

Medical Conditions File contains

Household reported data

Data on Conditions

Data on Procedures

Page 17: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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

Page 18: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

MEPS Condition Roster

One roster per person Cumulates medical conditions reported across MEPS interviews Interviewer records verbatim responses to questions in the following 4 sections:

– Condition Enumeration– Priority Conditions (yes/no)– Medical Events – Disability

Page 19: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Condition Enumeration

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.

Page 20: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Condition Enumeration

Asked in every round

Has a time frame (since last interview until today)– Responses recorded verbatim and coded into 5

digit ICD9 codes– Responses directly linked to conditions roster– Chronic/priority conditions appear only once on

the roaster– Acute conditions can have many records– Responses aggregated across rounds for the

annual responses

Page 21: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Priority Conditions

New section since Panel 12 Separate section of questionnaire Series of questions asking if “ever” had

condition– “yes/no” responses, no ICD9 coding– responses of yes with a current utilization

record will appear on person’s condition roster Factors used in determining priority

conditions– Prevalence– Expenditures– Policy relevance

Page 22: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Priority Conditions List

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

Page 23: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Medical Events

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?

Page 24: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Event Count Variables

Indicates number of events associated with condition for person:– Home Health (HHNUM)– Inpatient stays (IPNUM)– Hospital outpatient (OPNUM)– Office-based (OBNUM)– Emergency room (ERNUM)– Prescription Medicine purchases

(RXNUM)

Page 25: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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?

Page 26: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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

Page 27: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Reporting and Recording Conditions

Respondents may report having the same condition more than once– Interviewer verifies that these are

different occurrences of the condition– Each unique episode of a condition is

recorded only once person may have more than one cold in a

year each cold has a separate record

Page 28: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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

Page 29: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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

Page 30: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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

Page 31: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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)

Page 32: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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

Page 33: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

National Estimates of Conditions

Most appropriate to estimate “treated prevalence”– MEPS website 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

Page 34: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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

Page 35: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Medical Expenditure Panel Survey

Health Care Utilization and Expenditures

Page 36: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Health Care Utilization

MEPS household respondents asked to report all health care use for family members during reference period

Utilization is called an “event” in MEPS Event type categories:

– Office-Based Medical Provider Visits (OB)– Hospital Inpatient Stays (IP)– Outpatient Department Visits (OP)– Emergency Room Visits (ER)– Dental Visits (DN)– Prescription Medicine Purchases (RX)– Home Health Care (HH)– Other Medical Expenses (OM)

Page 37: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

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

Page 38: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Source of Payment Categories

Page 39: AHRQ 2011 Annual Conference AHRQ Data Resources to Inform Health Policy Research: The Medical Expenditures Panel Survey (MEPS) Anita Soni, Ph.D

Sources of Expenditure Data

Expenditures derived from two survey components:– Medical Provider Component (MPC)– Household Component (HC)

MPC data used when available HC data used when no MPC data

available Events with no MPC or HC data on

expenditures are imputed– results in no missing values
