购买医疗保健服务要算成本、定价格。交易上常受供方支付法、实际成本、供应量、供应结果以及供需双方特点而定。供量要合宜,避免过多时滥用,少了又供不应求,价格要公道。定价常受供方决策权的强弱,订合同和开展竞争上有多少能量的影响。费用支付或按人头、或依疾病诊断分类(DRG),或按服务项目计算三种方法为主。对低、中等收入国家,由于信息不够,对支付系统的了解受到妨碍。 The purchase of health care services is based on cost and set prices. Transactions are often subject to supplier payment methods, actual costs, supply, supply results, and characteristics of the supply and demand sides. The amount of supply should be appropriate, and abuse should be avoided when there is too much, and supply should not be provided. The price must be fair. Pricing is often influenced by the strengths of the supplier’s decision-making power, and how much energy is affected by contracting and competing. Expenses are paid or per head, or according to DRG, or three methods based on service items. For low- and middle-income countries, knowledge of payment systems is hampered due to insufficient information.
