To estimate the clinical and economic effects of available invasive and noninvasive management strategies for peptic ulcer and Helicobacter pylori in persons with symptoms suggesting peptic ulcer disease.
Cost-effectiveness analysis using a decision analytic model.
2 immediate endoscopy and 3 noninvasive diagnostic and treatment strategies were evaluated: 1) immediate endoscopy for peptic ulcer and biopsy for H. pylori; 2) immediate endoscopy without biopsy; 3) serologic test for H. pylori; 4) empiric treatment with antisecretory therapy; and 5) empiric treatment with antisecretory therapy and antibiotic agents to eradicate H. pylori.
Cost per ulcer cured and cost per patient treated.
The estimated costs per ulcer cured by strategy were as follows: 1) endoscopy and biopsy for H. pylori, $8045; 2) endoscopy without biopsy, $6984; 3) serologic test for H. pylori, $4541; 4) empiric antisecretory therapy, $4835; and 5) empiric antisecretory and antibiotic therapy, $4155. The predicted costs per patient treated were as follows: 1) endoscopy and biopsy for H. pylori, $1584; 2) endoscopy without biopsy, $1375; 3) serologic test for H. pylori, $894; 4) empiric antisecretory therapy, $952; and 5) empiric antisecretory and antibiotic therapy, $818. The cost-effectiveness advantage of the noninvasive strategies diminished as the cost of endoscopy decreased or as the probability of recurrent symptoms increased in patients initially managed without endoscopy.
Endoscopy, although costly, precisely guided diagnosis and treatment and thus potentially reduced the number of patients inappropriately treated. However, the safety and effectiveness of less expensive, less invasive diagnostic and treatment strategies strongly support initial noninvasive care of symptomatic persons thought to have peptic ulcer disease.
评估针对有消化性溃疡症状者的现有侵入性和非侵入性管理策略对消化性溃疡和幽门螺杆菌的临床及经济效果。
使用决策分析模型进行成本效益分析。
评估了2种即时内镜检查及3种非侵入性诊断和治疗策略:1)针对消化性溃疡进行即时内镜检查及幽门螺杆菌活检;2)不进行活检的即时内镜检查;3)幽门螺杆菌血清学检测;4)使用抗分泌疗法进行经验性治疗;5)使用抗分泌疗法和抗生素根除幽门螺杆菌的经验性治疗。
治愈每个溃疡的成本及每位接受治疗患者的成本。
各策略治愈每个溃疡的估计成本如下:1)幽门螺杆菌内镜检查及活检,8045美元;2)不进行活检的内镜检查,6984美元;3)幽门螺杆菌血清学检测,4541美元;4)经验性抗分泌疗法,4835美元;5)经验性抗分泌及抗生素疗法,4155美元。每位接受治疗患者的预测成本如下:1)幽门螺杆菌内镜检查及活检,1584美元;2)不进行活检的内镜检查,1375美元;3)幽门螺杆菌血清学检测,894美元;4)经验性抗分泌疗法,952美元;5)经验性抗分泌及抗生素疗法,818美元。随着内镜检查成本降低或初始未接受内镜检查患者复发症状概率增加,非侵入性策略的成本效益优势减弱。
内镜检查虽成本高昂,但能精准指导诊断和治疗,从而可能减少不适当治疗的患者数量。然而,成本较低、侵入性较小的诊断和治疗策略的安全性和有效性有力支持了对疑似患有消化性溃疡疾病的有症状者进行初始非侵入性治疗。
