Adherence to standard infection control precautions (SICP) by radiographers is critical in combating healthcare associated infections (HAIs). Therefore, radiographers need to have adequate knowledge and practices of infection control if they are to contain the magnitude of HAIs.
Purposive, all-inclusive sampling was used to recruit 62 radiographers from four government referral hospital in Malawi. Radiographers' knowledge and practices of infection control were determined using a self-administered questionnaire. Data collection was carried out in January 2017. Descriptive (e.g. mean and standard deviation) and inferential (Chi test) statistics were generated using an MS Excel VBA application.
The majority of the respondents (84%) were between 20 and 39 years of age. The study results revealed that radiographers in the four hospitals had mean infection control score (percentage) of 76.8 ± 12.6 for knowledge and a mean infection control score of 65.3 ± 16.1 for practice. A slight significant association between age and knowledge (p < 0.05; Cramer's V 0.26) was found in that radiographers between 40 and 59 years of age (majority of the sample) obtained higher knowledge scores than those 20-39 years of age.
Given the results, further training is required regarding infection control among radiographers in radiology departments in Malawi. A guideline for infection control, specifically contextualised to be used by radiographers in radiology departments in Malawi, should be developed and implemented to enhance adherence to SICP in these departments.
放射技师遵守标准感染控制预防措施（SICP）对于对抗医疗保健相关感染（HAIs）至关重要。因此，如果放射技师要控制HAIs的规模，就需要具备足够的感染控制知识和实践能力。
采用目的抽样和全包含抽样的方法，从马拉维的四家政府转诊医院招募了62名放射技师。通过自行填写的问卷来确定放射技师的感染控制知识和实践情况。数据收集于2017年1月进行。使用MS Excel VBA应用程序生成描述性统计（如均值和标准差）和推断性统计（卡方检验）。
大多数受访者（84%）年龄在20至39岁之间。研究结果显示，四家医院的放射技师在知识方面的平均感染控制得分（百分比）为76.8±12.6，在实践方面的平均感染控制得分为65.3±16.1。发现年龄与知识之间存在轻微显著关联（p<0.05；克莱姆系数V为0.26），即40至59岁的放射技师（样本中的大多数）获得的知识得分高于20至39岁的放射技师。
鉴于这些结果，马拉维放射科的放射技师需要接受关于感染控制的进一步培训。应制定并实施专门针对马拉维放射科放射技师使用的感染控制指南，以加强这些科室对SICP的遵守。
