综合干预措施提高痰标本质量的效果评价

目的通过综合干预，提高痰标本采集、送检质量。方法收集某院2011年2-10月住院患者常规留取、自然咯痰法咯出的痰标本。2011年5月始对呼吸科病区进行干预（干预组，采取跟踪反馈、继续教育、健康宣教等综合干预措施），住院部其他病区作为对照组，通过对痰标本的采集、送检状况和质量的调查，对干预措施的效果进行评价。结果采取综合干预措施后，干预组干预后痰标本的合格率为41.94%，显著高于对照组的21.62%（χ2=18.76，P＜0.05）；亦高于干预组干预前的痰标本合格率 24.19%（χ2=10.85，P＜0.05）。结论临床常规留取痰标本质量合格率偏低，综合干预措施的实施可以提高痰标本合格率。

Evaluation on efficacy of improving sputum specimen quality through bundle of interventions

ObjectiveTo improve the quality of sputum specimen collection through a bundle of interventions.MethodsSputum specimens of patients who were hospitalized between February and October 2011 were collected through routine method. Intervention in respiratory department was carried out from May 2011（intervention group, follow up and feed back, continuing education, as well as health education were carried out）, the other inpatient departments was as control group, the efficacy of intervention was evaluated through investigation on sputum collection, delivery and quality. Results After intervention, the qualified rate of sputum specimens of the intervention group was 41.94%, which was significantly higher than 21.62% of control group （χ2=18.76, P〈0.05） and 24.19% of intervention group before intervention （χ2=10.85, P〈0.05）. ConclusionThe qualified rate of routinely collected sputum specimens is low, the quality of sputum specimens can be improved by a bundle of interventions.
