Abstract

PURPOSE

To assess the status of quality management systems in computed tomography (CT) facilities in Ghana.

METHODS

A questionnaire and quality control measurements were used to assess the status of quality management systems in CT facilities in Ghana. Thirty-one CT facilities took part in the study. The evaluation included quality assurance (QA), quality control (QC), and quality improvement (QI).

RESULTS

Seventeen (54.8%) of the 31 CT facilities had a QA-QC committee in place to ensure patient protection. Fifteen facilities (48.4%) had documented protocols for CT scanning. Ten facilities (32.3%) lacked QC assessment and recordkeeping after notable repairs. Regular QC check records were available in 20 (64.5%) facilities. All scanners passed the QC assessments; however, none of the facilities had established local diagnostic reference levels.

DISCUSSION

Quality management systems in some Ghanian CT facilities are unsatisfactory; not all facilities have the needed infrastructure in place for quality management system purposes.

CONCLUSION

Quality management systems in Ghanaian CT facilities should be strengthened to optimize patient protection and safety with acceptable image quality.

摘要

目的

评估加纳计算机断层扫描（CT）设备的质量管理体系状况。

方法

采用问卷调查和质量控制测量方法评估加纳CT设备的质量管理体系状况。31家CT设备参与了该研究。评估内容包括质量保证（QA）、质量控制（QC）和质量改进（QI）。

结果

31家CT设备中有17家（54.8%）设立了QA-QC委员会以确保患者安全。15家设备（48.4%）有CT扫描的书面协议。10家设备（32.3%）在进行重大维修后缺乏QC评估和记录保存。20家（64.5%）设备有定期QC检查记录。所有扫描仪均通过了QC评估；然而，没有一家设备建立了当地的诊断参考水平。
