Objectives:Uganda, has limited health resources and improving performance of personnel involved in imaging is necessary for efficiency. The objectives of the study were to develop and pilot imaging user performance indices, document non-tangible aspects of performance, and propose ways of improving performance.Materials and Methods:This was a cross-sectional survey employing triangulation methodology, conducted in Mulago National Referral Hospital over a period of 3 years from 2005 to 2008. The qualitative study used in-depth interviews, focus group discussions, and self-administered questionnaires, to explore clinicians’ and radiologists’ performancerelated views.Results:The study came up with following indices: appropriate service utilization (ASU), appropriateness of clinician's nonimaging decisions (ANID), and clinical utilization of imaging results (CUI). The ASU, ANID, and CUI were: 94%, 80%, and 97%, respectively. The clinician's requisitioning validity was high (positive likelihood ratio of 10.6) contrasting with a poor validity for detecting those patients not needing imaging (negative likelihood ratio of 0.16). Some requisitions were inappropriate and some requisition and reports lacked detail, clarity, and precision.Conclusion:Clinicians perform well at imaging requisition-decisions but there are issues in imaging requisitioning and reporting that need to be addressed to improve performance.

“…For example, technological innovation in imaging and interventional technologies has intensified the demand on radiologists to assimilate the proliferation of new information to deliver safe and cost-effective care, 11 12 and the promotion of new tests may occur prior to published evidence supporting widespread use. EBM use within radiology has not been examined, but a survey of radiation oncologists found widespread support for EBM, although most had not undertaken formal EBM training and were unaware of integral resources such as the Cochrane Library.…”

Radiologists’ perspectives about evidence-based medicine and their clinical practice: a semistructured interview study

ObjectivesTo describe radiologist's attitudes and perspectives on evidence-based medicine (EBM) and their practice.DesignFace-to-face semistructured interviews, thematic analysis.Setting24 institutions across six Australian states and New Zealand. Transcripts were imported into HyperRESEARCH software and thematically analysed.Participants25 radiologists.ResultsSix themes were identified: legitimising decisions (validated justification, prioritising patient preferences, reinforcing protocols), optimising outcomes (ensuring patient safety, maximising efficiency), availability of access (requiring immediacy, inadequacy of evidence, time constraints, proximity of peer networks, grasping information dispersion), over-riding pragmatism (perceptibly applicability, preserving the art of medicine, technical demands), limited confidence (conceptual obscurity, reputation-based trust, demands constant practice, suspicion and cynicism), and competing powers (hierarchical conflict, prevailing commercial interests).ConclusionsRadiologists believe EBM can support clinical decision-making for optimal patient outcomes and service efficiency but feel limited in their capacities to assimilate and apply EBM in practice. Improving access to evidence, providing ongoing education and training supplemented with practical tools for appraising evidence; and developing evidence-based guidelines and protocols may enhance feasibility and promote the confidence and skills among radiologists in applying EBM in radiology practice for better patient care.

“…Evidence-based decision-making, including decision support tools and appropriate use criteria (AUC), can enhance the sustainability of medical imaging by reducing low-value studies. 41 Low-value imaging contributes to unnecessary GHG emissions and potentially harms patients through radiation exposure, testing, and interventions that cause individuals anxiety and system-level strain. 42 Up to 20% of medical imaging tests are considered low-value 43 and recent efforts have focused on addressing this issue.…”

The environmental impact of magnetic resonance imaging (MRI) has recently come into focus. This includes its enormous demand for electricity compared to other imaging modalities and contamination of water bodies with anthropogenic gadolinium related to contrast administration. Given the pressing threat of climate change, addressing these challenges to improve the environmental sustainability of MRI is imperative. The purpose of this review is to discuss the challenges, opportunities, and the need for action to reduce the environmental impact of MRI and prepare for the effects of climate change. The approaches outlined are categorized as strategies to reduce greenhouse gas (GHG) emissions from MRI during production and use phases, approaches to reduce the environmental impact of MRI including the preservation of finite resources, and development of adaption plans to prepare for the impact of climate change. Co‐benefits of these strategies are emphasized including lower GHG emission and reduced cost along with improved heath and patient satisfaction. Although MRI is energy‐intensive, there are many steps that can be taken now to improve the environmental sustainability of MRI and prepare for the effects of climate change. On‐going research, technical development, and collaboration with industry partners are needed to achieve further reductions in MRI‐related GHG emissions and to decrease the reliance on finite resources.Level of Evidence5Technical EfficacyStage 6
