- Clinical audit and quality improvement of the imaging departmentsPublication . Almeida, Rui; Silva, Carlos Otero; Gama, Zenewton; Abrantes, AntónioDue to the nature of imaging departments, clinical audit, quality improvement and safety topics have specific components that are not observed in other services or departments, as they have the particularity of performing imaging procedures that involve the application of ionizing radiation, in most cases 1. Within the complexities of these procedures, the patient's inability to choose the best procedure stands out, leaving the healthcare professionals involved the responsibility to select the best patient-centred procedure, with the application of the most effective and efficient protocol depending on the patient clinical situation, based on the available evidence, and applying the lowest radiation dose possible. This poster intends to address a set of tools aiming to assess professional performance and encourage changes in the practices adopted, such as Clinical Audit, Evidence-based Practice and Guidelines, which can be integrated in a major concept of clinical governance as a system of measures and procedures to deliver the best care to the patient.
- Comparative dose measurements in dentomaxillofacial imaging procedures: are Barium and Bismuth shields useful for the protection of eyes and thyroid glands?Publication . Almeida, Rui; Abrantes, António; Silva, Carlos OteroDose measurements were performed at the eye lens and thyroid level using TLD dosimeters, in different configurations (with and without shields) and using standard protocols with different values of voltage (kV) and current-time product (mAs). A total of 103 exposures were performed on patients, 84 of them using a MSCT GE Lightspeed 16 equipment and the remaining 19 using a CBCT NewTom GiANO equipment. These exposures were subdivided into 22 smaller samples (19 samples with 5 exposures each, 1 sample with 4 exposures and 2 samples with 2 exposures each), in accordance with the protocols and configurations adopted. 54 were performed without the use of shields and the remaining 49 with the use of shields, namely, a bismuth shield for the thyroid, a barium shield for the eye lens and, also, a bismuth shield for the breast, which was tested only in the routine MSCT protocol.
