ADDRESS

Definition

PURPOSE: To allow an estimate of the extent and type of health care services available in the participant’s vicinity to evaluate how community impacts outcomes.

Geographic identifiers of address and years at address, including the following variables:

Authorization received for collection of street address
Street address 1
City
State

The National Data and Statistical Center will obtain Geo-ID codes on a quarterly basis utilizing addresses provided.

Zip Code of location where person with brain injury is living: - at the time just prior to index TBI (ZipInj) - at discharge from Rehabilitation (ZipDis) - at time of follow-up evaluation (ZipF)

Calculated variable converting various intervals to a standardized format is available.

Details

AddressConsentF - Participants should be given the option of opting out of this component of data collection

Leave address fields blank if not applicable or unknown.

If participant is living in a boat, RV or other living situation where they “take their home with them”, record the address they use as their permanent address.

If participant is living in a boat, RV or other living situation where they “take their home with them” and travel frequently (vs. boat being ‘permanently’ docked, or RV being stationary) then skip the GEO-ID question and code zip code as ‘88888- Not Applicable’, as this item is used to look at services available in participant’s area.

ZipDis- Record zip code of first place the person goes after discharge, regardless of how long he/she resided there.

If the person has no residence, record the zip code of the area in which he/she is most likely to be (for example, the homeless shelter they use).

CULTURAL

Definition

Primary Language spoken in the participant’s home
To code this variable, participants will be asked;
“Before the injury, what was the primary language spoken in your home?” (Form 1)
“What is the primary language spoken in your home?” (Form 2)

Languages other than English or Spanish will be recorded in a secondary text field.

Country of birth; To code this variable, participants will be asked “What is your country of birth?” Countries other than the United States will be recorded in a secondary text field.

Years in US; The number of years that a participant has lived in the United States (if they were not born in the US). To code this variable, participants who report a country of birth other than the United States will be asked “How many years have you been in the United States?”

Form

[X] Form 1
[X] Form 2

Source

Form I - Pre-Injury History (participant or proxy)
Form 2 - Interview, Mail-Out (participant or proxy)

Details

For participants enrolled prior to addition of this variable, ask the question at the time of the next Form 2 follow-up.

Primary Language

If 2 or more languages are spoken in the home, try to get the participant to choose which language they consider to be the primary language.

Country of Birth

Country of Birth for participants enrolled prior to addition of this variable; ask the question at the time of the next Form 2 follow-up.

If born in Puerto Rico count as born in the US.

Years in US

This question should only be asked of participants whose country of birth is other than the United States. Therefore, it should be asked after the question on country of birth.

Begin by asking the number of years participants have been in the United States. If less than 1 year, then ask number of months. Code 6 months or greater as 1 year. Code less than 6 months as 0 years.

If participants have lived in the United States intermittently, with periods separated by time spent in another country, record the total number of years spent in the United States. Example - Participant has spent 3-4 months of every year in the US for the last 30 years. To determine the total number of years spent in the US, multiply the 30 years by 3.5 months (mid-point of a “3 - 4” month range). That gives us a total of 105 months in the US. Divide that by 12 months for a total of 8.75 years, and then round up for a total of 9 years spent in the US.

Characteristics

Recommendations for using data collected at Form 2 include two options:

Only use a given response at the time it was collected when analyzing data from that year. This would limit sample size but would be the most accurate use of the variable reflecting the participant’s self-report of length of time in the U.S. at that moment.
Use the variable to derive a value representing a common time point across all individuals who immigrated to the U.S. Any calculated variables derived from this would have to be understood as an estimate and reported as such in publications. For example:
1. Estimated Age of Entry Into the U.S.
  i. Subtracting current age at the time of the response from the reported length of time in the U.S. would be an estimate of age of entry into the U.S. with the understanding that this represents an upper estimate.
  ii. True age of entry may be younger for individuals who have lived for one or more years outside of the U.S. after their initial immigration.
2. Estimated Years in the U.S. at the Time of Injury.
  i. For those who were asked this question at a follow-up time point, subtracting the years since injury at the time this was asked from the response provided would estimate time in the U.S. at the time of injury.
  ii. This can result in a negative number as in this example:

Someone from abroad visiting U.S. relatives has a TBI. After rehabilitation, they return to their home country. They then immigrate to live in the U.S. for 3 years. At their year 5 follow-up, they state they have been living in the U.S. for 3 years. Subtracting 5 from this value results in -2 years in the U.S. at the time of injury.

In this case, the value can be counted as 0 years in the U.S. at the time of injury.

Source

Form 1 Height - Abstraction (acute or rehab record) Form 2 HeightF - Interview, Mail-out (participant or proxy) Form 1 Weight - Abstraction (acute record) Form 2 WeightF - Interview, Mail-Out (participant or proxy)

Details

Height at baseline can be collected from either the acute hospital medical record or rehabilitation record.

Weight should reflect the first measurement taken during acute hospitalization using a scale or bed scale. If unable to determine if recorded weights were measured using a scale or bed scale, use the first recorded weight in the acute hospital medical record. EMS or paramedic reports should not be used to collect weight.

Round up if half inches or pounds are reported.

If the participant notes any arm or leg amputation(s) when asked about height and weight, code 888 - Not Applicable (Any Arm Or Leg Amputation). The Data Collector does NOT need to probe for amputations when asking the height and weight questions.

If there is a height discrepancy between Form 1 and any height reported during follow-up, height should be verified at the next follow-up, and the discrepancy should be corrected on the Form 1 or Form 2 (database and paper file).

RACE

Definition

Ethnicity - Self-reported Ethnicity for two categories: “Hispanic, Latino, or Spanish”, and “Not Hispanic, Latino, or Spanish”. To code this variable, participants are asked “Are you of Hispanic, Latino, or Spanish origin?”

Race - Self-Reported racial identification for each of the following five categories: “White”, “Black, African American”, “Asian”, “American Indian or Alaskan Native”, and “Native Hawaiian or other Pacific Islander”. To code these variables, participants are asked “What racial group or groups do you most identify as?”. To account for mixed race, all race categories that a participant indicates should be coded.

Form 1 - Follow-up question is asked if more than one race or ethnicity is asked to capture primary race participant identies as - “If you selected more than one race or ethnicity, with which do you identify most strongly?”

Form

[X] Form 1
[X] Form 2

Source

Form I - Pre-Injury History (participant or proxy)
Form 2 - Interview, Mail-Out (participant or proxy)

Details

Patient’s or significant other’s statement is preferred to hospital record information.

Record participant’s statement regarding his/her race, or record race of father.

In obtaining a statement from the participant regarding his/her race/ethnicity, ambiguity may be resolved by asking which race/ethnicity is more important in his/her daily life.

It is acceptable to collect RACE variables from an SO if individual cannot answer for themselves.

The RACE questions are to be asked only once, NOT at every follow-up.

Characteristics

Added CHARACTERISTICS: on 1/15/2023, “What is your race?” was removed from Form 1 data collection and replaced with race questions from Form 2 - “Are you of Hispanic, Latino, or Spanish origin?; and “What racial group or groups do you most identify as? (Select all that apply)”; Race as a single variable is mapped to RacePrimary to ensure consistency with prior data collection

New follow-up question - “If you identified with more than one race in the above questions, what is the race you identify with the most?” was added on 4/1/2023 - This was to insure a crosswalk with the Race variable that was asked prior to the Race Ethnicity split.

Code “6-Biracial or Multiracial” added to Primary Race Question on 10/1/2023

RESIDENCE

Definition

Where the person with brain injury is living:
ResInj - residence at the time just prior to injury

ResF - residence at the time of follow-up evaluation, according to the best source of information (person with brain injury unless unavailable or unreliable)

Residence Codes
1 - Private Residence Includes house, apartment, mobile home, foster home, condominium, dormitory (school, church, college), military barracks, boarding school, boarding home, rooming house, bunk-house, boys ranch, fraternity/sorority house, commune, migrant farmworkers camp
2 - Nursing Home/Subacute Care Includes medi-center, residential, institutions licensed as hospitals but providing essentially long-term, custodial, chronic disease care, etc.
3 - Adult Home Includes adult foster care, indep. living center, transitional living facility, assisted living, supported living, group home
4 - Correctional Institution Includes prison, jail, penitentiary, correctional center, labor camp, halfway house, etc.

Details

If there is uncertainty regarding residence, treat it as a self-report variable. If residence is not clear, a reliable respondent (when possible, the person with TBI) should be asked, eg., “Where were you [the person with TBI] living (‘prior to injury’, or at ‘follow-up’)?”. If the response is ambiguous (as may happen, eg., if the person is transient) use probes in order to adequately understand the respondent’s belief regarding residence, then code that. Do not probe to obtain additional objective information about the living situation and then (the data collector) use that information in determining the correct code. When residence is at all ambiguous, treat it as a self-report variable.

Patients discharged to temporary living facilities while still enrolled in outpatient programs should be coded according to the level of supervision or assistance they receive. If the facility is for the use of patients and their families, code these transitional residences as “private residence” rather than an “adult home/transitional living facility”, as supervision or assistance in this setting would be provided by the family member or the attendant residing with the person, rather than by a staff overseeing a group of individuals which is more typical in an “adult home/transitional living facility.”

If participant is still in the hospital at follow-up, data collectors are encouraged to find out reason for hospitalization and if they will be discharged while still in the follow-up window. If participant is expected to still be hospitalized when the window closes, then code as ‘7-Hospital (Acute Care)’.

Code government or non-profit subsidized SRO (Single Resident Occupancy) housing as “3-Adult Home (Includes adult foster care, independent living center, transitional living facility, assisted living, supported living, group home)”. Even though some of these vary from a single private room within a larger building or a full apartment, the space that they occupy could be viewed as a transitional and supported living situation given that it is not a permanent housing solution and/or it is funded by government/subsidy.

Participants living in a boat, RV or other living situation where they “take their home with them” should be coded as “Private Residence”.

DEMOGRAPHICS - CALCULATED

Definition

AGE, AGEF This calculated variable determines the precise age, in full years, of the participant by comparing their fixed Date of Birth (Birth) against a flexible Reference Date (Injury Date or Follow-up Date). This logic is designed to be mathematically accurate, ensuring that the age in years reflects whether the participant’s birthday had passed as of the specified reference date.

The “No PHI” distinction cuts off the age at 89 and greater

BMI (Body Mass Index at Injury) (kg/m2) is calculated from height in inches and weight in pounds as [weight/(height)^2]*703

BMI Category classifies BMI into categories between severely underweight to very severely obese, using the BMI calculated from height and weight

GEOGRAPHIC IDENTIFIERS (GEO-ID) - CALCULATED

Definition

PURPOSE: To allow an estimate of the extent and type of health care services available in the participant’s vicinity to evaluate how community impacts outcomes.

The geographic identifier (geo-id) variables listed below are retrieved quarterly from the U.S. Census website. They are aligned with a TBIMS participant’s address, which is collected at Form 2. An individual subject may have multiple addresses (collected at different follow-up time points) and therefore multiple sets of geo-id variables. At each quarterly submission, new geo-id variables are added to correspond to newly-collected addresses. If a participant did not consent to have their address collected, they will not have any geo-id data associated with them. All of the following variables are of String type.

CensusTract – This is a unique, 11-digit code that identifies a census tract within a certain state/county. Census tract numbers are not unique across states and counties. This 11-digit code has been concatenated with a 2-digit state code (StateCode) and a 3-digit county code (CountyCode) to form a unique, 11-digit census tract code.
CensusBlock – This is a non-unique, 4-digit census block code from the U.S. Census. Census block numbers are not unique across states and counties. This code must be concatenated with a 2-digit state code (StateCode) and a 3-digit county code (CountyCode) to form a unique, 9-digit census block code.
StateCode – This is a 2-digit state code from the U.S. Census.
CountyCode – This is a 3-digit county code from the U.S. Census.
TractString – This is a non-unique, 6-digit census tract code from the U.S. Census. Census tract numbers are not unique across states and counties. This code is concatenated with the 2-digit state code (StateCode) and the 3-digit county code (CountyCode) to form the CensusTract variable.

Variables

Form Type	Variable	Question
Form 2	CensusBlock	Census Block
Form 2	CensusTract	The 11-digit census tract that is a concatenation of STATEA, COUNTYA, and TRACTA
Form 2	CountyCode	County code from U.S. Census
Form 2	StateCode	State Code from U.S. Census
Form 2	TRACTA	This is a non-unique, 6-digit census tract code from the U.S. Census. Census tract numbers are not unique across states and counties. This code is concatenated with the 2-digit state code (StateCode) and the 3-digit county code (CountyCode) to form the CensusTract variable.

SOCIOECONOMIC STATUS - CALCULATED

Definition

PURPOSE: To provide information on aspects of the socioeconomic status (SES) in the participant’s vicinity to evaluate how community impacts outcomes.

SES variables were downloaded from the IPUMS (originally, the “Integrated public Use Microdata Series”) website that houses data from the American Community Survey. The SES variables align with census tracts, not TBIMS participants. A TBIMS participant may have multiple census tracts associated with them, one for each follow-up interview where they consented to have their address collected. If a participant did not consent to have their address collected, they will not have any SES data associated with them. Additional variables that provide metadata (information about when the SES data was collected) are included as well. All of the following variables are of String type.

GeoYear – The five-year aggregate American Community Survey dataset that indicates the year the SES variables were collected. For example, a value of 2015-2019 indicates that the SES variables were collected in 2019.
TBIMS_NSDI_2019 – This variable contains a value that indicates the neighborhood disadvantage of a census tract, called the TBI Model Systems Neighborhood Socioeconomic Disadvantage Index. The value can be negative or positive. Positive values indicate more disadvantage. The TBI Model Systems Neighborhood Socioeconomic Disadvantage Index was calculated in 2019 using the first dimension of a principal components analysis of eight census-tract SES indicators (Percent unemployed, Percent Single Parent Led Households, Percent no HS or GED, Percent Bachelor’s Degree or Higher, Percent below the poverty line, Percent of households that were on food stamps/SNAP, Median Household Income, Median Family Income). The index did NOT use the race/ethnicity variables (PercentWhite, PercentBlack, PercentHispanic) in their construction. You can find the specifics of this variable’s creation in Kumar RG, Delgado A, Corrigan JD, Eagye CB, Whiteneck GG, Juengst SB, Callender L, Bogner J, Pinto SM, Rabinowitz AR, Perrin PB, Venkatesan UM, Botticello AL, Lequerica AH, Taylor S, Zafonte RD, Dams-O’Connor K. (2024). The TBI Model Systems Neighborhood Socioeconomic Disadvantage Index (TBIMS-NSDI): Development and Comparison to Individual Socioeconomic Characteristics. J Head Trauma Rehabil. There will be a new TBIMS_NSDI variable every ten years, separate from this one, denoted by the 4-digit year at the end of the variable name.
GeoStatus – This is an indicator variable with a value of Interim or Final. The most recent SES status variables come from the 2015-2019 date range in the American Community Survey (ACS), which is where the data is sourced. There is typically a two-year lag between when the ACS data is collected and when it is available to the public. Therefore, it is possible to have a TBIMS participant’s follow-up date be more recent than the GeoYear. The GeoStatus variable shows whether the date of collection of the SES variables lags the follow-up interview date when a participant’s address was collected (Interim), or whether the two dates match (Final).
PercentUnemployed – The percentage of civilian unemployed (people 16 and over). The formula used to create PercentUnemployed is (# civilian unemployed / # in labor force).
PercentSingleHoH – The percentage of single parent headed households with children <18. The formula used to create PercentUnemployed is ((# male household + # female household) / # in family households).
PercentNoHSorGED – The percentage of people >=25 years old without a high school diploma or GED. The formula used to create PercentNoHSorGED is (No schooling completed + Nursery school + Kindergarten + 1st through 11th grade + 12th grade, no diploma)/Total in CensusTract.

Variables

Form Type	Variable	Question	History
Form 2	ACSYEARS	The five-year aggregate dataset imported from IPUMS.

Form 2	GeoStatus	This is an indicator variable with a value of Interim or Final. The most recent SES status variables come from the 2015-2019 date range in the American Community Survey (ACS), which is where the data is sourced. There is typically a two-year lag between when the ACS data is collected and when it is available to the public. Therefore, it is possible to have a TBIMS participant’s follow-up date be more recent than the GeoYear. The GeoStatus variable shows whether the date of collection of the SES variables lags the follow-up interview date when a participant’s address was collected (Interim), or whether the two dates match (Final).
