The costs and effects of introducing selectively trained radiographers reporting accident and emergency (A&E) radiographs of the appendicular skeleton in a district general hospital were assessed using a retrospective controlled before and after design. Reference standard reports were compared with a random stratified sample of 200 A&E and 200 general practitioner (GP) reports before and after the intervention. GP reports were used as a non-intervention, non-equivalent control group. An A&E specialist registrar judged whether incorrect A&E reports might have a clinically important effect on patient management. The effect of incorrect A&E reports on outcome was assessed by patient re-attendance to the hospital because of missed abnormalities. The annual, average and incremental costs of radiographers and radiologists reporting A&E radiographs were calculated and a sensitivity analysis was undertaken. The introduction of the radiographers resulted in a 1% (95% CI -7.9 to 5.9) fall in A&E radiograph reporting accuracy and 11% (95% CI -33.7 to 11.3) reduction of cases in which incorrect A&E reports might have a clinically important effect on patient management. Only two A&E reports (one before and one after the intervention) affected patient outcome in that a fracture missed at the first visit resulted in patient re-attendance to the X-ray Department. There was a saving of 361 pounds per annum to the X-ray Department. In conclusion this study provides further evidence that selectively trained radiographers can accurately report A&E plain radiographs and at no additional cost.
采用回顾性干预前后对照设计,评估了在一家地区综合医院引入经过专门培训的放射技师报告四肢骨骼急诊(A&E)X光片的成本和效果。在干预前后,将参考标准报告与200份A&E报告及200份全科医生(GP)报告的随机分层样本进行比较。GP报告用作非干预、非等效对照组。一名A&E专科住院医师判断不正确的A&E报告是否可能对患者管理产生临床重要影响。因遗漏异常情况导致患者再次到医院就诊来评估不正确的A&E报告对结果的影响。计算了放射技师和放射科医生报告A&EX光片的年度、平均和增量成本,并进行了敏感性分析。引入放射技师后,A&EX光片报告准确性下降了1%(95%CI -7.9至5.9),不正确的A&E报告可能对患者管理产生临床重要影响的病例减少了11%(95%CI -33.7至11.3)。只有两份A&E报告(干预前一份,干预后一份)影响了患者结果,即首次就诊时漏诊的骨折导致患者再次到X光科就诊。X光科每年节省361英镑。总之,本研究提供了进一步的证据,表明经过专门培训的放射技师可以准确报告A&E平片,且无需额外成本。
