The aim of the study was to assess the knowledge and practices of primary care physicians in diagnosis and management of Helicobacter pylori (H. pylori) infection in developing country.
This convenient sample based, cross sectional study was conducted in primary care physicians of Karachi, Pakistan from March 2008 to August 2008 through a pretested self-designed questionnaire, which contained 11 items pertaining to H. pylori route of transmission, diagnosis, indication for testing, treatment options, follow up and source of information.
Out of 509 primary care physicians, 451 consented to participate with the response rate of 88.6%. Responses of 426 primary care physicians were analyzed after excluding 19 physicians. 78% of the physicians thought that contaminated water was the source of spread of infection, dyspepsia was the most frequent indication for investigating H. pylori infection (67% of the physicians), while 43% physicians were of the view that serology was the most appropriate test to diagnose active H. pylori infection. 77% of physicians thought that gastric ulcer was the most compelling indication for treatment, 61% physicians preferred Clarithromycin based triple therapy for 7-14 days. 57% of the physicians would confirm H. pylori eradication after treatment in selected patients and 47% physicians preferred serological testing for follow-up. In case of treatment failure, only 36% of the physicians were in favor of gastroenterologist referral.
The primary care physicians in this study lacked in knowledge regarding management of H. pylori infection. Internationally published guidelines and World gastroenterology organization (WGO) practice guideline on H. pylori for developing countries have little impact on current practices of primary care physicians. We recommend more teaching programs, continuous medical education activities regarding H. pylori infection.
本研究旨在评估发展中国家基层医疗医生在幽门螺杆菌(H. pylori)感染诊断和管理方面的知识与实践。
本基于便利抽样的横断面研究于2008年3月至2008年8月在巴基斯坦卡拉奇的基层医疗医生中进行,通过一份预先测试的自行设计问卷进行调查,该问卷包含11项有关幽门螺杆菌传播途径、诊断、检测指征、治疗方案、随访及信息来源的内容。
在509名基层医疗医生中,451名同意参与,应答率为88.6%。排除19名医生后,对426名基层医疗医生的回答进行了分析。78%的医生认为受污染的水是感染传播源,消化不良是调查幽门螺杆菌感染最常见的指征(67%的医生),而43%的医生认为血清学是诊断活动性幽门螺杆菌感染最合适的检测方法。77%的医生认为胃溃疡是最迫切的治疗指征,61%的医生倾向于使用基于克拉霉素的三联疗法治疗7至14天。57%的医生会在选定患者治疗后确认幽门螺杆菌根除情况,47%的医生倾向于进行血清学检测以进行随访。在治疗失败的情况下,只有36%的医生赞成转诊至胃肠病专家处。
本研究中的基层医疗医生在幽门螺杆菌感染管理知识方面存在欠缺。国际上发表的指南以及世界胃肠病学组织(WGO)针对发展中国家的幽门螺杆菌实践指南对基层医疗医生的当前实践影响甚微。我们建议开展更多关于幽门螺杆菌感染的教学项目和继续医学教育活动。
