Health care spending varies in unexplained ways, and physicians' behavior is thought to explain much of the variation. We studied the spending effects of having different usual sources of care, focusing on variations associated with the type of facility or physician specialty. Based on analyses of data from the 2001-2004 Medical Expenditure Panel Surveys, we found significant differences in annual spending, especially for adults. Use of and spending for subspecialists were similar to those for general internists, and both were significantly higher than those for family physicians. Variation in spending might be the result of training differences among primary care specialties.
医疗保健支出以无法解释的方式存在差异，而医生的行为被认为可以解释大部分差异。我们研究了不同常规医疗来源对支出的影响，重点关注与医疗机构或医生专业类型相关的差异。基于对 2001-2004 年医疗支出调查数据的分析，我们发现年度支出存在显著差异，尤其是对于成年人。专科医生的使用和支出与普通内科医生相似，均明显高于家庭医生。支出的差异可能是由于初级保健专业之间的培训差异所致。
