Estimates and Patterns of Direct Health Care Expenditures Among Individuals With Back Pain in the United States

To estimate total health care expenditures incurred by individuals with back pain in the United States, calculate the incremental expenditures attributable to back pain among these individuals, and describe health care expenditure patterns of individuals with back pain. SUMMARY OF BACKGROUND DATA: There is a lack of updated information on health care expenditures and expenditure patterns for individuals with back pain in the United States.

This study used data from the 1998 Medical Expenditure Panel Survey, a national survey on health care utilization and expenditures. Total health care expenditures and per-capita expenditures among individuals with back pain were calculated. Multivariate regression models were used to estimate the incremental expenditures attributable to back pain. The expenditure patterns were examined by stratifying individuals with back pain by sociodemographic characteristics and medical diagnosis, and calculating per-capita expenditures for each stratum.
