This study examined the impact of managed care and other environmental factors on hospital inefficiency in 1631 US hospitals during the period 1990-1996. A panel, stochastic frontier regression model was used to estimate inefficiency parameters and inefficiency scores. The results suggest that mean estimated inefficiency decreased by about 28% during the study period. Inefficiency was negatively associated with health maintenance organization (HMO) penetration and industry concentration. It was positively related with Medicare share and for-profit ownership status.
本研究考察了1990 - 1996年期间管理式医疗及其他环境因素对美国1631家医院效率低下的影响。采用面板随机前沿回归模型来估计无效率参数和无效率得分。结果表明，在研究期间，平均估计的无效率下降了约28%。无效率与健康维护组织（HMO）的渗透率和行业集中度呈负相关。它与医疗保险份额和营利性所有制状况呈正相关。
