INTRODUCTION High quality diagnostic imaging can provide increased diagnostic accuracy and help guide medical decision-making and management, however challenges for radiology in resource-limited settings are numerous. Diagnostic imaging and teleradiology have financial and logistical implications, so evidence of impact is crucial. We sought to test the hypothesis that the implementation of computed radiography with teleradiology consultation support will significantly change diagnoses and treatment plans in a resource limited setting. METHOD Paired before-after study to determine the therapeutic impact of an add-on diagnostic test. 'Preliminary Plan' and 'Final Plan' forms allowed direct comparison of diagnosis and treatment plans at initial consultation and following radiography and teleradiology. Consecutive consenting patients were included until the sample size (600) was reached. Changes in both diagnosis and treatment plan were analysed in the whole cohort, with sub-analyses of children aged <5 years, and cases of chest radiography. RESULTS Final analysis included 536 cases. Diagnosis changed following radiography and teleradiology in 62% of cases, and treatment plans changed in 61%. In chest radiography cases, 70% of diagnoses and 62% of treatment plans changed, while in children <5 years 66% of diagnoses and 58% of treatment plans changed. Reduced final treatment plans were most common for exploratory surgery (72% decrease), surgical orthopaedic intervention (62% decrease), and TB treatment (52% decrease), allowing more conservative medical or surgical management in 61 cases. Increased final treatment plans were highest in the orthopaedic and interventional surgery and referral categories. Of 42 cases requiring interventional surgery in the final plan, 26 (62%) were identified only after radiography and teleradiology. 16 additional cases were indicated for orthopaedic surgery, 10 cases required patient transfer, and TB treatment was indicated in 45 cases. A change in the original prescription plan occurred in 41% of 536 cases, with one or more prescriptions stopped in 28% of all cases. CONCLUSION We found that computed radiography with teleradiology had significant clinical value in this resource-limited setting, with the potential to affect both patient outcomes and treatment costs through providing improved diagnostics and avoiding unnecessary treatments and medications.

计算机放射学和远程放射学对刚果民主共和国姆韦索患者诊断和治疗的影响。



引言 高质量诊断成像可以提高诊断准确性,并帮助指导医疗决策和管理,但在资源有限的环境中,放射学面临着许多挑战。诊断成像和远程放射学具有财务和后勤影响,因此影响的证据至关重要。我们试图检验这样一个假设:在资源有限的情况下,实施计算机放射成像和远程放射学咨询支持将显着改变诊断和治疗计划。方法 前后配对研究以确定附加诊断测试的治疗影响。 “初步计划”和“最终计划”表格允许在初次咨询以及放射线照相和远程放射学之后直接比较诊断和治疗计划。连续同意的患者被纳入其中,直到达到样本量(600)。对整个队列的诊断和治疗计划的变化进行了分析,并对<5岁儿童和胸部X光检查病例进行了亚分析。结果最终分析536例。 62% 的病例在放射线照相和远程放射学后诊断发生改变,61% 的治疗计划发生改变。在胸部X光检查病例中,70%的诊断和62%的治疗计划发生了变化,而在5岁以下的儿童中,66%的诊断和58%的治疗计划发生了变化。减少最终治疗计划最常见的是探查手术(减少 72%)、骨科介入治疗(减少 62%)和结核病治疗(减少 52%),这使得 61 例病例可以采取更保守的药物或手术治疗。最终治疗计划的增加在骨科和介入手术以及转诊类别中最高。 最终计划中需要介入手术的 42 例病例中,有 26 例(62%)是在放射线摄影和远程放射学检查后才确诊的。另外 16 例需要进行骨科手术,10 例需要患者转移,45 例需要结核病治疗。 536例中,41%的患者改变了原来的处方计划,28%的患者停止了一张或多张处方。结论 我们发现,在这种资源有限的环境中,采用远程放射学的计算机放射成像具有显着的临床价值,有可能通过提供改进的诊断并避免不必要的治疗和药物来影响患者的治疗结果和治疗成本。
