摘　　要：目的 调查基层医院加速器使用情况,探索国产加速器的优势与不足.方法 选择使用国产加速器和进口加速器的基层医院各26家,成组t检验差异.结果 （1）26家进口设备平均治疗2808人/d,26家国产设备平均治疗3923人/d（P=045）.（2）设备品牌、治疗人数及开展的治疗技术和医院级别无明显关系.（3）被调查单位需引进放疗医生、物理师和技师的比例分别为878%、776%、878%.（4）国产和进口品牌在采购成本、维护成本之间差异显著（P=000、004）,在产品服务、适用性、易用性以及设备稳定性方面均相近（P=0.21-100、0.15-052、0.07-100）.（5）国产设备在小剂量重复性方面较差,在设备故障远程诊断方面尚是空白.结论 国产加速器基本能满足基层医院目前需求且综合成本低于进口加速器,大多数调查和测试指标和进口加速器相当,但国产加速器在小剂量重复性、远程诊断和计划系统方面有较大提升空间.Objective To investigate the application of accelerators in primary hospitals, and to explore the advantages and disadvantages of domestic accelerators. Methods Twenty-six primary hospitals that used domestic accelerators and an equal number of primary hospitals that used imported accelerators were enrolled in the study. Comparison was made by group t test. Results （ 1） The mean numbers of patients treated every day were 2808 for the 26 hospitals with imported accelerators and 3923 for the 26 hospitals with domestic accelerators （ P=045 ） . （ 2 ） There was no significant relationship of hospital level with equipment brand, the number of treated patients, or treatment technology.（3） The proportions of hospitals that need to employ radiotherapy doctors, physical therapists, and technicians were 878%, 776%, and 878%, respectively.（4） The purchasing and maintenance costs were significantly higher for the imported accelerators than for the domestic ones （ P=000, 004）;there were no significant differences in product service, applicability, convenience, or stability between imported and domestic accelerators （ P= 021-100,015-052,007-100）.（5） For the domestic accelerators, the repeatability was poor in the low-dose treatment, and the remote diagnosis of equipment failure was not yet achieved. Conclusions Domestic accelerators can meet the basic requirements of primary hospitals. Compared with imported ones, domestic accelerators have lower total costs but comparable indices in most investigations and tests. In terms of repeatability of the low-dose treatment, remote diagnosis, and planning system, however, domestic accelerators still have a long way to go.
