Correctable vision impairment caused by refractive error is common in the United States population. We estimated the direct costs of providing eyeglasses to all Americans (age> or =12) who need refractive correction to achieve good distance vision.
Cross-sectional study of a nationally representative sample of United States citizens.
Participants in the 1999-2002 National Health and Nutrition Examination Survey (NHANES), age > or = 12 years. The NHANES examines a nationally representative sample of the U.S. noninstitutionalized, civilian population.
Presenting and corrected visual acuity data were obtained using an autorefractor from 13,211 (93.0%) of the 14,203 participants who visited the NHANES Mobile Examination Center in 1999 through 2002. Need for refractive correction was defined by current use of corrective lenses for distance vision, improvement to good visual acuity following autorefractor correction (using several cutpoints to define good visual acuity), or both.
Estimates of direct cost for refractive correction (1 pair of complete eyeglasses and a refraction examination) were computed based on Centers for Medicare & Medicaid Services fee schedules for 2000 and also based on expenditure data from the Medical Expenditure Panel Survey.
The NHANES results indicate that >110 million Americans could or do achieve normal vision with refractive correction. The annual direct cost of correcting distance vision impairment is at least $3.8 billion. Of this amount, $780 million represents the annual cost of providing distance vision correction for persons > age 65.
Correctable vision impairment due to refractive error is common in the United States population. These cost estimates provide useful information for public health endeavors aimed at provision of refractive correction to those who need it.
屈光不正导致的可矫正视力损害在美国人群中很常见。我们估算了为所有需要屈光矫正以获得良好远视力的美国人(年龄≥12岁)提供眼镜的直接成本。
对具有全国代表性的美国公民样本进行横断面研究。
1999 - 2002年国家健康与营养检查调查(NHANES)中年龄≥12岁的参与者。NHANES对美国非机构化平民人口的全国代表性样本进行检查。
通过自动验光仪从1999年至2002年访问NHANES流动检查中心的14203名参与者中的13211名(93.0%)获取了初始视力和矫正视力数据。屈光矫正需求通过当前使用远视力矫正镜片、自动验光仪矫正后视力提高到良好视力(使用多个切点定义良好视力)或两者来定义。
基于2000年医疗保险和医疗补助服务中心的收费标准以及医疗支出小组调查的支出数据,计算屈光矫正(一副完整眼镜和一次验光检查)的直接成本估算。
NHANES结果表明,超过1.1亿美国人通过屈光矫正能够或确实获得了正常视力。矫正远视力损害的年度直接成本至少为38亿美元。其中,7.8亿美元是为65岁以上人群提供远视力矫正的年度成本。
屈光不正导致的可矫正视力损害在美国人群中很常见。这些成本估算为旨在为有需要者提供屈光矫正的公共卫生工作提供了有用信息。
