To assess health-seeking behaviour among adults with prolonged cough in a population-based, nationally representative sample in Vietnam.
Cross-sectional survey conducted from September 2006 to July 2007. All inhabitants aged ≥15 years were invited for screening for cough, history of tuberculosis (TB) treatment and chest X-ray (CXR) examination. TB suspects, defined as any survey participant with CXR abnormalities consistent with TB, or productive cough for more than 2 weeks or TB treatment either currently or in the preceding 2 years submitted sputum specimens for smear examination and culture and provided information on health-seeking behaviour in an in-depth interview.
Of 94 179 persons participating in the survey, 4.6% had prolonged productive cough. Forty-four percentage of those had sought health care and reported pharmacies (35%), commune health posts (29%), public hospitals (24%) and private physicians (10%) as first point of contact. Only 7% had undergone sputum smear examination. Of TB suspects with prolonged productive cough, 2.9% were diagnosed with TB; 10.2% of these reported smear and 21.9% reported X-ray examination when visiting a health care facility. The average patient delay was 4.1 weeks (95% CI: 3.9-4.4) among cough suspects and 4.0 weeks (95% CI: 3.1-4.9) among TB cases.
In this Vietnamese survey, nearly half of persons with cough for more than 2 weeks had visited a health care provider. The commonest first health facility contacted was the pharmacy. Sputum smears were rarely examined, except in the provincial TB hospital. Our findings highlight the need to improve diagnostic practices by retraining health staff on the performance of sputum examination for TB suspects.
在越南一项基于人群、具有全国代表性的样本中,评估持续性咳嗽成年人的求医行为。
2006 年 9 月至 2007 年 7 月进行横断面调查。所有年龄≥15 岁的居民均被邀请参加咳嗽筛查、结核病(TB)治疗史和胸部 X 线(CXR)检查。TB 疑似病例定义为任何 CXR 异常与 TB 一致的调查参与者,或目前或过去 2 年内有 2 周以上持续咳嗽或接受过 TB 治疗者,需留取痰标本进行涂片检查和培养,并在深入访谈中提供求医行为信息。
在 94179 名参与调查的人群中,4.6%有持续性咳嗽。其中 44%的人寻求过医疗保健,并报告了药店(35%)、社区卫生站(29%)、公立医院(24%)和私人医生(10%)作为第一接触点。仅有 7%的人接受了痰涂片检查。在有持续性咳嗽的 TB 疑似病例中,2.9%被诊断为 TB;其中 10.2%在就诊时报告了涂片检查,21.9%报告了 X 射线检查。咳嗽疑似病例的平均患者延迟时间为 4.1 周(95%CI:3.9-4.4),TB 病例的平均患者延迟时间为 4.0 周(95%CI:3.1-4.9)。
在这项越南调查中,超过 2 周咳嗽的人群中,近一半人曾就诊于医疗保健机构。最常接触的第一家医疗机构是药店。除了在省级结核病医院外,很少进行痰涂片检查。我们的研究结果强调了需要通过重新培训卫生人员进行 TB 疑似病例的痰检来改进诊断实践。
