Delays in diagnosis and initiation of effective treatment increase morbidity and mortality from tuberculosis as well as the risk of transmission in the community. The aim of this study was to determine the time taken for patients later confirmed as having TB to present with symptoms to the first health provider (patient delay) and the time taken between the first health care visit and initiation of tuberculosis treatment (health service delay). Factors relating to these 'delays' were analyzed.
A cross-sectional survey, of 231 newly diagnosed smear-positive tuberculosis patients was conducted in Mulago National referral Hospital Kampala, from January to May 2002. Socio-demographic, lifestyle and health seeking factors were evaluated for their association with patient delay (> 2 weeks) and health service delay (> 4 weeks), using odds ratios with 95% confidence intervals (CI) including multivariate logistic regression.
The median total delay to treatment initiation was 12 weeks. Patients often presented to drug shops or pharmacies (39.4%) and private clinics (36.8%) more commonly than government health units (14%) as initial contacts. Several independent predictors of 'patient delay' were identified: being hospitalized (odds ratio [0R] = 0.32; 95% CI: 0.12-0.80), daily alcohol consumption (OR = 3.7; CI: 1.57-9.76), subsistence farming (OR = 4.70; CI: 1.67-13.22), and perception of smoking as a cause of TB (OR = 5.54; CI: 2.26-13.58). Independent predictors of 'health service delay' were: > 2 health seeking encounters per month (OR = 2.74; CI: 1.10-6.83), and medical expenditure on TB related symptoms > 29 US dollars (OR = 3.88; CI: 1.19-12.62). Perceived TB stigma and education status was not associated with either form of delay.
Delay in diagnosis of TB is prolonged at the referral centre with a significant proportion of Health service delay. More specific and effective health education of the general public on tuberculosis and seeking of appropriate medical consultation is likely to improve case detection. Certain specific groups require further attention. Alcoholics and subsistence farmers should be targeted to improve accessibility to TB treatment. Continuing medical education about TB management procedures for health providers and improvement in the capacity of TB control services should be undertaken.
结核病诊断和有效治疗的延迟会增加结核病的发病率和死亡率,以及社区传播风险。本研究的目的是确定后来确诊为结核病的患者出现症状后到首次就诊于医疗服务提供者的时间(患者延迟),以及从首次就诊到开始结核病治疗的时间(卫生服务延迟)。分析了与这些“延迟”相关的因素。
2002年1月至5月,在坎帕拉穆拉戈国家转诊医院对231例新诊断的涂片阳性结核病患者进行了横断面调查。评估社会人口统计学、生活方式和就医因素与患者延迟(>2周)和卫生服务延迟(>4周)的关联,采用比值比及95%置信区间(CI),包括多因素逻辑回归分析。
开始治疗的总延迟中位数为12周。患者最初常就诊于药店或药房(39.4%)和私人诊所(36.8%),而非政府卫生机构(14%)。确定了几个“患者延迟”的独立预测因素:住院(比值比[OR]=0.32;95%CI:0.12 - 0.80)、每日饮酒(OR = 3.7;CI:1.57 - 9.76)、自给农业(OR = 4.70;CI:1.67 - 13.22)以及认为吸烟是结核病病因(OR = 5.54;CI:2.26 - 13.58)。“卫生服务延迟”的独立预测因素为:每月就医次数>2次(OR = 2.74;CI:1.10 - 6.83)以及与结核病相关症状的医疗支出>29美元(OR = 3.88;CI:1.19 - 12.62)。感知到的结核病耻辱感和教育程度与任何一种延迟形式均无关联。
在转诊中心,结核病诊断延迟时间延长,卫生服务延迟占很大比例。对公众进行更具体、有效的结核病健康教育以及寻求适当的医疗咨询可能会改善病例发现情况。某些特定群体需要进一步关注。应针对酗酒者和自给农业从业者,以改善其获得结核病治疗的机会。应为卫生服务提供者开展关于结核病管理程序的继续医学教育,并提高结核病控制服务能力。
