An economic option appraisal to determine whether early investment in capital is an efficient means of expanding radiation therapy services.
Costs were based on 1991 data from a center in western Sydney. Two options were costed: Option 1 based on an increase in overtime performed by existing staff, using capital more intensively and possible use of shifts; Option 2 based on an investment in new capital and associated increases in levels of staffing. The health sector costs of both options were determined in one center at workloads of between 70,940 and 98,525 fields per year to assess relative efficiency.
There was very little difference in cost between both options, with Option 1 slightly cheaper at workloads up to 98,525 fields per year.
The results suggest that capital investment may be introduced at a fairly early stage without efficiency loss. Sensitivity analysis reinforces these conclusions and the generalizability of the results.
进行一项经济方案评估，以确定早期资本投资是否是扩大放射治疗服务的有效手段。
成本基于悉尼西部一个中心1991年的数据。对两种方案进行了成本核算：方案1基于现有员工加班增加、更密集地使用资本以及可能采用轮班制；方案2基于新资本投资及相关人员配备水平的提高。在一个中心确定了两种方案在每年70940至98525野工作量下的卫生部门成本，以评估相对效率。
两种方案的成本差异极小，在每年高达98525野的工作量下，方案1略便宜。
结果表明，可在相当早的阶段引入资本投资而不会造成效率损失。敏感性分析强化了这些结论以及结果的普遍性。
