In addition to the survey data, we merged our NLTCS
file with several types of individual-level administrative data, including Minimum Data Set (MDS) assessments, Medicare fee-for-service claims, Medicare denominator files, and vital statistics files.
Persons were included in this study if: (1) the NLTCS
sample person was alive in 1991, (2) the sample person died between January 1, 1996 and December 31, 2000, (3) there were 5 years of continuous Medicare records for the individual, and (4) the person was not in Medicare MCOs during the last 5 years of life.

We specified four mutually exclusive cognition groups: (1) good cognition, with a score of 24 or higher; (2) poor cognition, with a score lower than 24; (3) a proxy was needed to complete the NLTCS
, in which case an MMSE score was not available; and (4) missing data, when an MMSE score was not available and the survey did not indicate use of a proxy respondent.
Expenditure data in the NLTCS
were limited to a time period of one month and may be high or low relative to annual expenditures or episodes of care expenditures for any respondent.
