It is recommended that magnetic resonance (MR) technologists should not work alone due to potential occupational health risks although lone working is legally acceptable. The objective of this study was to investigate the current situation of lone working MR technologists in Western Australia (WA) and any issue against the regulations.
A questionnaire regarding the issues of occupational health of lone working MR technologists was developed based on relevant literature and distributed to WA MR technologists. Descriptive (percentage of frequency, mean and standard deviation) and inferential statistics (Fisher's exact, Chi(2) and t tests, and analysis of variance) were used to analyze the responses of the yes/no, multiple choice and 5 pt scale questions from the returned questionnaires.
The questionnaire response rate was 65.6% (59/90). It was found that about half of the MR technologists (45.8%, 27/59) experienced lone working. The private magnetic resonance imaging (MRI) centers were more likely to arrange technologists to work alone (p < 0.05). The respondents expressed positive views on issues of adequacy of training and arrangement, confidence and comfort towards lone working except immediate assistance for emergency (mean: 3). Factors of existence of MRI safety officer (p < 0.05) and nature of lone working (p < 0.001-0.05) affected MR technologists' concerns.
Lone working of MR technologists is common in WA especially in private centers. The training and arrangement provided seem to be adequate for meeting the legal requirements. However, several areas should be improved by the workplaces including enhancement on immediate emergency assistance and concern relief.
尽管单独工作在法律上是可接受的，但由于存在潜在的职业健康风险，建议磁共振（MR）技术人员不要单独工作。本研究的目的是调查西澳大利亚州（WA）单独工作的MR技术人员的现状以及任何违反规定的问题。
基于相关文献制定了一份关于单独工作的MR技术人员职业健康问题的问卷，并分发给WA的MR技术人员。使用描述性统计（频率百分比、均值和标准差）和推断性统计（Fisher精确检验、卡方检验和t检验以及方差分析）来分析回收问卷中是/否、多项选择和5分制问题的回答。
问卷回复率为65.6%（59/90）。发现约一半的MR技术人员（45.8%，27/59）经历过单独工作。私立磁共振成像（MRI）中心更有可能安排技术人员单独工作（p<0.05）。除了紧急情况下的即时援助（均值：3）外，受访者对培训和安排的充分性、对单独工作的信心和舒适度等问题表达了积极看法。MRI安全官员的存在因素（p<0.05）和单独工作的性质（p<0.001 - 0.05）影响了MR技术人员的担忧。
MR技术人员单独工作在WA很常见，尤其是在私立中心。提供的培训和安排似乎足以满足法律要求。然而，工作场所应在几个方面加以改进，包括加强即时紧急援助和缓解担忧。
