Consolidation of physician practices by hospitals, or vertical integration, increased across all practice types in 2007-17. Rates of growth were highest among medical and surgical specialty practices and lowest among primary care practices. There was substantial variation within the specialties, ranging from 4 percentage points in dermatology to 34 percentage points in cardiology and oncology.
2007 年至 2017 年期间，医院对医生执业机构的整合（即纵向整合）在所有执业类型中都有所增加。增长率最高的是内科和外科专业实践，增长率最低的是初级保健实践。各专业之间存在着巨大的差异，从皮肤科的 4 个百分点到心脏病学和肿瘤学的 34 个百分点不等。
