In Ghana, there is a need to document computed tomography (CT) infrastructure and management systems for the development of interventions to promote CT practices while ensuring patient protection through the establishment of diagnostic reference levels and improved dose management systems.
A quantitative inquiry using a descriptive, cross-sectional approach was used to collect data, using a semistructured questionnaire related to CT infrastructure and management from the technical heads responsible for CT scanners. Data collected included the scanner characteristics, basic management system and organizational arrangements, number of attending practitioners, clinical indications for CT examinations, and the operation of CT facilities in Ghana.
Of the 35 CT scanners installed across the country, 31 were involved in the study. The majority (29%) were Toshiba models. Equipment slices ranged from 1 to 640, of which 45.2% were 16-slice scanners. Many (n = 28, 90.3%) were functioning, and most were installed in the capital city, Accra. The equipment mean age was 7.3 ± 4.4 years, and 25.6% were 10 or more years old. There were 107 operating radiographers, 60 reporting radiologists, and 10 medical physicists employed across the facilities. A total of 204,760 CT examinations were performed yearly (6.8 CT procedures per 1000 people in Ghana). Head CT procedures were the most common, and suspicion of cerebrovascular accident or stroke (32.8%) was the most common indication. Some basic quality management system and policy driving CT infrastructure in Ghana were lacking.
The results have provided essential information on the status of CT infrastructure and management systems for policy development and planning in CT facilities in Ghana. This study provides those interested in CT services, jobs, or medical equipment investment in Ghana the information needed to make appropriate decisions.
在加纳,需要记录计算机断层扫描(CT)基础设施和管理系统,以制定干预措施,促进 CT 实践,同时通过建立诊断参考水平和改进剂量管理系统来保护患者。
采用描述性、横断面研究方法进行定量调查,使用与 CT 基础设施和管理相关的半结构化问卷,向负责 CT 扫描仪的技术负责人收集数据。收集的数据包括扫描仪的特点、基本管理系统和组织安排、主治医生的数量、CT 检查的临床指征以及加纳 CT 设施的运行情况。
在全国安装的 35 台 CT 扫描仪中,有 31 台参与了这项研究。大多数(29%)是东芝型号。设备切片范围从 1 到 640,其中 45.2%是 16 层扫描仪。许多(n=28,90.3%)在正常运行,而且大多数都安装在首都阿克拉。设备平均年龄为 7.3±4.4 岁,25.6%的设备使用时间超过 10 年。在这些设备中,共有 107 名在职放射技师、60 名报告放射科医生和 10 名医学物理学家。每年共进行 204760 次 CT 检查(加纳每 1000 人中有 6.8 次 CT 检查)。头部 CT 检查最为常见,怀疑脑血管意外或中风(32.8%)是最常见的指征。加纳的一些基本质量管理系统和政策缺乏对 CT 基础设施的推动。
这些结果提供了有关加纳 CT 基础设施和管理系统状况的重要信息,为加纳 CT 设施的政策制定和规划提供了依据。本研究为那些对 CT 服务、工作或医疗设备投资感兴趣的人提供了在加纳做出适当决策所需的信息。
