| 摘 要： | 目的通过对两台CR和DR机作测试比较,分别求得CR和DR在实际运行中各自的人均检查成本,反映两种机种不同的综合运行成本,可供医院管理层人员参考。方法分别实际测试每一个患者每次检查所花费的平均检查时间,而计算出该台设备使用率在80%的情况下每天可检查的人数,再分别根据两台设备的投资成本和运行成本,除以每天可检查人数,得出人均检查成本。结果CR机和DR机使用率在80%时每天可检查人数分别为82人和154人,通过计算分别得出CR系统和DR系统假定每天检查人数为100人时,其人均检查成本分别为10.92元和11.81元;假定CR和DR每天检查人数增为200人时,则CR和DR的人均成本分别为7.19和5.98元。结论当一天的患者人数少于80人时,CR的检查成本相对比DR较为低;患者数在80-100人/天时CR和DR两者成本差别不大;但一天患者检查人数多于100人时则DR系统的检查成本相对更低。文中还围绕影响工作效率的其他因素,对CR和DR各自的优点和不足作了评价。 |

| Abstract: | Objective Through the testing and comparing of CR and DR machine, the per capita inspection costs of CR and DR were obtained respectively in practical operations,which could reflect different synthetic operating costs of this two machines and provide references for the hospital administrators. Methods The average time of each inspections for one person was tested, and then calculated the number of people when the utilization rate of the machine was 80% per day. We could obtain the per capita costs of inspec... |
