OBJECTIVES: To compare concordance of survey reports of health service use versus claims data between self respondents and spousal and nonspousal relative proxies.
DATA SOURCES: 1995-2010 data from the Survey on Assets and Health Dynamics among the Oldest Old and 1993-2010 Medicare claims for 3,229 individuals (13,488 person-years).
STUDY DESIGN: Regression models with individual fixed effects were estimated for discordance of any hospitalizations and outpatient surgery and for the numbers of under- and over-reported physician visits.
PRINCIPAL FINDINGS: Spousal proxies were similar to self respondents on discordance. Nonspousal proxies, particularly daughters/daughters-in-law and sons/sons-in-law, had less discordance, mainly due to reduced under-reporting.
CONCLUSIONS: Survey reports of health services use from nonspousal relatives are more consistent with Medicare claims than spousal proxies and self respondents.
