Managed care health plans, particularly health maintenance organizations (HMOs), have been shown to reduce the level of health care spending. Their ability to constrain the long-term rate of health care cost growth is less certain and will depend largely on their ability to constrain the use of emerging medical technologies. Evidence from experience with one important medical technology, laparoscopic cholecystectomy, suggests no systematic difference between HMOs and the general population in the rate of growth in utilization following the introduction of new medical technology.
管理式医疗健康计划，尤其是健康维护组织（HMOs），已被证明能够降低医疗保健支出水平。它们抑制医疗保健成本长期增长率的能力尚不确定，这在很大程度上取决于它们抑制新兴医疗技术使用的能力。一项重要医疗技术——腹腔镜胆囊切除术的经验证据表明，在引入新医疗技术后，HMOs与普通人群在利用率增长速度方面没有系统性差异。
