Secondary analysis of the 1998 Medical Expenditure Panel Survey.
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.
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.
In 1998, total health care expenditures incurred by individuals with back pain in the United States reached 90.7 billion dollars and total incremental expenditures attributable to back pain among these persons were approximately 26.3 billion dollars. On average, individuals with back pain incurred health care expenditures about 60% higher than individuals without back pain (3,498 dollars vs. 2,178 dollars). Among back pain individuals, at least 75% of service expenditures were attributed to those with top 25% expenditure, and per-capita expenditures were generally higher for those who were older, female, white, medically insured, or suffered from disc disorders.
Health care expenditures for back pain in the United States in 1998 were substantial. The expenditures demonstrated wide variations among individuals with different clinical, demographic, and socioeconomic characteristics.
对1998年医疗支出面板调查进行二次分析。
估算美国背痛患者的总医疗保健支出，计算这些患者中因背痛产生的额外支出，并描述背痛患者的医疗保健支出模式。
美国缺乏关于背痛患者医疗保健支出及支出模式的最新信息。
本研究使用了1998年医疗支出面板调查的数据，该调查是一项关于医疗保健利用和支出的全国性调查。计算了背痛患者的总医疗保健支出和人均支出。使用多元回归模型估算因背痛产生的额外支出。通过按社会人口统计学特征和医学诊断对背痛患者进行分层，并计算各层的人均支出，来研究支出模式。
1998年，美国背痛患者产生的总医疗保健支出达到907亿美元，这些患者中因背痛产生的总额外支出约为263亿美元。平均而言，背痛患者产生的医疗保健支出比无背痛患者高出约60%（3498美元对2178美元）。在背痛患者中，至少75%的服务支出归因于支出最高的25%的患者，年龄较大、女性、白人、有医疗保险或患有椎间盘疾病的患者人均支出通常更高。
1998年美国用于背痛的医疗保健支出数额巨大。这些支出在具有不同临床、人口统计学和社会经济特征的患者中存在很大差异。
