S. Tepper et al., ALTERNATIVE DEFINITIONS OF DISABILITY - RELATIONSHIP TO HEALTH-CARE EXPENDITURES, Disability and rehabilitation, 19(12), 1997, pp. 556-558
The purpose of this study is to investigate the relationship between d
ifferent definitions of disability and health-care expenditures in the
working aged population in the United States using the 1987 National
Medical Expenditure Survey (NMES). Five different definitions of disab
ility were identified and the health-care expenditures for each group
were compared using descriptive analyses. Results reveal that estimate
s of the prevalence of disability vary dramatically by the definition
of disability. A more than three-fold difference in average total heal
th-care expenditures is observed using different specifications of dis
ability. These results suggest that estimates of health-care expenditu
res should be interpreted cautiously, since the definition influences
the magnitude of estimates. Researchers and policy-makers should consi
der the standardization of the term 'disability'.
