BACKGROUND
Spirometry is an important tool when diagnosing chronic respiratory conditions in general practice. However, the equipment may harbour pathogenic micro-organisms and cross-transmission of aerolised pathogens could occur if hygiene measures are insufficient.
METHODS
We assessed microbiological contamination in 16 spirometers from a convenience sample of South Australian general practices. Results We found potentially relevant microbiological contamination in three spirometers: two Pseudomonas spp.; one coagulase negative Staphylococcus sp. and one Alcaligenes sp. Although the three practices concerned all reported to have a written spirometer cleaning protocol in place, the frequency of spirometer disinfection did not match the manufacturers'
DISCUSSION
Despite the small size of our study sample, we found potentially relevant microbiological contamination in 3 out of 16 spirometers from metropolitan general practices. The potential hazard of spirometers as reservoirs of microorganisms stresses the need for stricter attention to hygiene measures for spirometer maintenance in general practices.
背景
在全科医疗中，肺活量测定法是诊断慢性呼吸道疾病的一项重要工具。然而，该设备可能藏有病原体微生物，如果卫生措施不到位，雾化病原体可能会发生交叉传播。
方法
我们对南澳大利亚州全科医疗便利样本中的16台肺活量测定仪进行了微生物污染评估。结果我们在三台肺活量测定仪中发现了潜在相关的微生物污染：两台假单胞菌属；一株凝固酶阴性葡萄球菌和一株产碱菌属。尽管相关的三家医疗机构均报告称已制定了书面的肺活量测定仪清洁方案，但肺活量测定仪的消毒频率与制造商的要求不符。
讨论
尽管我们的研究样本规模较小，但我们在来自大都市全科医疗的16台肺活量测定仪中，发现有3台存在潜在相关的微生物污染。肺活量测定仪作为微生物储存库的潜在危害，强调了在全科医疗中更严格关注肺活量测定仪维护卫生措施的必要性。
