This study was part of a major review of long-term care policy in the state of Ohio. The authors analyzed 1532 cost reports filed by nursing homes in 1975-1976 with the Ohio Medical Assistance (Medicaid) program. The objective was to guide policy on size (economies of scale), ownership, certification status, and reimbursement. Economies of scale were not found important: skilled nursing facilities (SNFs) offered the only evidence of operation below optimal scale, and the savings attributable to achieving optimal scale (increasing average bed size from 108 to 143) amounted to only $0.20 per patient day. Proprietary facilities were consistently less costly than voluntary or governmental facilities; however, quality measures were not available, and the largest cost differential was in direct cost where quality might be affected. Hypothesized greater efficiency in proprietary facilities could not be rejected--if accurate, the cost savings were very large ($3.92 to $9.14 per patient day for all homes together). As expected, skilled facilities were more costly than intermediate care facilities (ICFs), and the differential ($3.31 per patient day) was large enough to suggest transfer of misplaced patients. High proportional Medicaid utilization of a home tended to reduce cost, possibly because of the very low ceiling rates paid by the Ohio Medicaid program during the period of this study (1975-76 data). High utilization in general reduced average cost, presumably by spreading fixed cost.
本研究是俄亥俄州长期护理政策重大审查的一部分。作者分析了1975 - 1976年疗养院向俄亥俄医疗救助(医疗补助)计划提交的1532份成本报告。目的是为有关规模(规模经济)、所有权、认证状态和报销的政策提供指导。未发现规模经济很重要:专业护理机构(SNFs)是唯一运营规模低于最优规模的证据,实现最优规模(将平均床位规模从108张增加到143张)带来的节省仅为每天每位患者0.20美元。私立机构的成本始终低于志愿或政府机构;然而,没有质量衡量标准,最大的成本差异在于可能影响质量的直接成本方面。私立机构效率更高的假设无法被推翻——如果准确的话,成本节省非常大(所有疗养院加起来为每天每位患者3.92美元至9.14美元)。正如预期的那样,专业护理机构比中级护理机构(ICFs)成本更高,差异(每天每位患者3.31美元)大到足以表明错放患者的转移。疗养院较高比例的医疗补助利用率往往会降低成本,可能是因为在本研究期间(1975 - 76年数据)俄亥俄医疗补助计划支付的费率上限非常低。总体而言,高利用率降低了平均成本,大概是通过分摊固定成本实现的。
