This study examines the impact of HMO penetration and competition on health system performance, as measured by hospital cost per adjusted admissions. The study population consisted of acute-care hospitals in the United States. The findings of this study suggest that there is no relationship between HMO competition and hospital cost per adjusted admission. Governmental efforts to stimulate competition in the hospital market, if focused on promoting HMOs, are not likely to produce cost-containing results quickly.
本研究考察了健康维护组织（HMO）的渗透和竞争对医疗系统绩效的影响，绩效以每例调整后住院病例的医院成本来衡量。研究对象为美国的急症医院。本研究结果表明，HMO竞争与每例调整后住院病例的医院成本之间不存在关联。政府若致力于刺激医院市场竞争并将重点放在推广HMO上，不太可能迅速产生控制成本的效果。
