The QuADRANT project: Enhancing quality and safety in radiological procedures through clinical audit

The project entitled "Quality Improvement Through Clinical Audit in Diagnostic (Including Interventional) Radiology, Radiotherapy and Nuclear Medicine (Including Therapies)" (QuADRANT) was conceived to thoroughly assess the state of clinical audit implementation across Europe, regarding the medical application of ionizing radiation. The central aim was to elevate the quality and safety standards in radiological procedures. This initiative arose from the understanding that consistent and rigorous clinical audit is fundamental for enhancing patient outcomes and adhering to safety regulations in cancer treatment using radiation. The project aimed to address the observed variations in how clinical audit was being applied across Europe.

The QuADRANT project employed a comprehensive methodology to gather data. This included an extensive review of existing literature, European regulations, and international guidelines pertinent to clinical audit in radiological procedures. National surveys were conducted, reaching out to representatives from European Union member states and other selected countries to collect information on national frameworks, methodologies, existing barriers, and facilitating factors. In-depth case studies, involving site visits and interviews with various stakeholders such as healthcare professionals and policymakers, provided deeper insights. Expert consultations with specialists in medical physics, radiation oncology, and quality assurance further enriched the data. Workshops were also held to engage national stakeholders in discussions about legal requirements, benefits, and good practices of clinical audit. The collected data was systematically analysed to identify key trends, common challenges, successful strategies, and areas ripe for improvement, leading to the formulation of evidence-based recommendations.

The project observed significant variations in the adoption and maturity of clinical audit programs across European countries, even within individual nations. While some countries demonstrated well-established practices, particularly concerning dosimetry audits in radiotherapy, a widespread and comprehensive clinical audit program covering all radiological procedures was often lacking. Data collection for audit purposes was frequently inconsistent, with common deviations from standard practice noted in patient data registration, diagnosis, treatment details, and the recording of adverse events. Many countries reported limited financial and human resources allocated to clinical audit. A general lack of awareness among healthcare professionals regarding the specific requirements and benefits of clinical audit was also identified. Organizational culture sometimes presented resistance to systematic quality improvement initiatives. Challenges were noted in data quality and the burden associated with manual data entry for audit purposes. Furthermore, a lack of central coordination at the national level often resulted in fragmented audit efforts.

The observed variations in clinical audit implementation highlight the necessity for a more harmonized and robust approach across Europe. The absence of standardized methodologies impedes effective benchmarking and the sharing of best practices among institutions and countries. The resource limitations and lack of awareness underscore a need for increased investment and targeted education campaigns to promote a culture of continuous quality improvement. The identified data collection inconsistencies indicate a critical area for intervention, suggesting the need for improved digital infrastructure and standardized reporting mechanisms to facilitate meaningful audits. For radiotherapy specifically, the findings emphasize that while some aspects like dosimetry are well-audited, a broader, more systematic audit of the entire treatment pathway, including advanced technologies and multidisciplinary team interactions, is often underdeveloped.

The QuADRANT project successfully provided a comprehensive overview of clinical audit practices in radiological procedures throughout Europe, identifying both achievements and substantial shortcomings. It underscored the critical need for strengthening national infrastructure, increasing resource allocation, and elevating the prioritisation of clinical audit. The project outcomes were published by the European Commission as part of Radiation Protection Series. Furthermore, the project's insights were instrumental in shaping the European Commission's recommendations on clinical audits establishing a crucial framework for harmonizing national clinical audit systems. The ongoing impact of the project is evident in subsequent initiatives like the Clinical Audit Implementation in Europe (CLAUD-IT) project on improving clinical audit practice in European Union member states radiological procedures.
