We present a study on the quality of operation and the characteristics of the medical imaging equipment in three specialty hospitals of the Mexican Health System. Six month residencies were carried out in order to better understand the problems and internal functioning of the three imaging departments. The kinds of equipment, the types of equipment failures and the internal operation of these services were analyzed. The results allow us to identify four factors that are linked to faults in the quality of the health care delivered to patients. The first factor is equipment obsolescence; the second is related to deficient preventive maintenance procedures and problems associated the supervising of external service providers. The third factor is derived from the equipment's (over) workload, which is indirectly tied to the age of the imaging modalities and the fourth factor is misuse of the equipment. The solutions to these problems include the modernization of the equipment and a better supervision by the clinical engineering department of all the processes involving the medical imaging services in each hospital. In addition to this, a special effort of the continuing education of personnel associated with medical imaging at all levels should be carried out.
我们展示了一项关于墨西哥卫生系统三家专科医院手术质量和医学成像设备特性的研究。开展了为期六个月的驻院实习，以便更好地了解这三个影像科的问题和内部运作情况。分析了设备种类、设备故障类型以及这些科室的内部运作。研究结果使我们能够确定与患者医疗服务质量缺陷相关的四个因素。第一个因素是设备过时；第二个因素与预防性维护程序不足以及与外部服务提供商监督相关的问题有关。第三个因素源于设备（过度）工作量，这与成像设备的使用年限间接相关，第四个因素是设备的滥用。这些问题的解决方案包括设备现代化以及临床工程部门对每家医院涉及医学成像服务的所有流程进行更好的监督。除此之外，还应特别努力对各级医学成像相关人员进行继续教育。
