医院市场的集中可能会限制依靠管理式医疗来限制成本的医疗改革战略的成功。医院市场容量也很重要，因为容量影响成本和价格竞争的程度。由于管理式护理计划，特别是非个人执业协会（非ipa）模式hmo，采用的是一种较少医院密集型的护理风格，医院市场的整合和缩小规模可能会伴随着管理式护理的增长，影响管理式护理成本控制策略的长期有效性。根据1982年和1987年的标准都市统计区（SMSA）数据，估计非ipa卫生组织市场份额每增加10个百分点，医院数量就会减少约4%，导致医院病床数量减少约5%。非ipa HMO普及率与医院入住率之间没有统计学上的显著关系。
Concentration in the hospital market could limit the success of health care reform strategies that rely on managed care to constrain costs. Hospital market capacity also is important because capacity affects both costs and the degree of price competition. Because managed care plans, particularly non-individual practice association (non-IPA) model HMOs, practice a less hospital-intensive style of care, consolidation and downsizing in the hospital market potentially will accompany managed care growth, influencing the long-run effectiveness of managed care cost-containment strategies. Using Standard Metropolitan Statistical Area (SMSA) data from 1982 and 1987, a 10-percentage point increase in non-IPA HMO market share is estimated to reduce the number of hospitals by about 4%, causing an approximate 5% reduction in the number of hospital beds. No statistically significant relationship is found between non-IPA HMO penetration rates and hospital occupancy rates.
