A growing body of evidence suggests that managed care can reduce overall health care costs but provides little insight into how this could happen. One possibility is that managed care influences the adoption of new medical technologies. In examining the relationship between health maintenance organization (HMO) activity and market-level availability and use of magnetic resonance imaging (MRI), we find that high HMO market share is associated with low levels of MRI availability and use. This suggests that managed care may be able to reduce health care costs by influencing the adoption and use of new medical equipment and technologies.
越来越多的证据表明，管理式医疗能够降低总体医疗成本，但对于其实现方式却知之甚少。一种可能性是，管理式医疗会影响新医疗技术的采用。在研究健康维护组织（HMO）的活动与市场层面磁共振成像（MRI）的可及性和使用情况之间的关系时，我们发现HMO的高市场份额与MRI的低可及性和低使用率相关。这表明管理式医疗或许能够通过影响新医疗设备和技术的采用与使用来降低医疗成本。
