Decision making is an essential skill necessary in a radiotherapy treatment unit to ensure timely and well-considered decisions, optimal care of all radiotherapy patients and to prevent adverse events/incidents that could cause harm to staff or patients. In order to achieve this utopia in radiotherapy, daily adaptation, continuous development, knowledge of our patient populations, understanding of clinical relevance, problem solving and critical thinking are essential. In my experience, critical thinking and daily adaptation are fundamental in the treatment unit. As a student, I used several adjectives when writing my learning objectives because I believe these are the core skills needed for decision making and providing optimal care in the processing unit. For example, question, analyze, synthesize, interpret, infer, induce/deduce. , develop, participate and solve problems. In my experience, in order to provide safe and high standard of care we need to use our ability to reason, reflect and judge, which is complemented by a mixed level of experience of the staff on the unit. It is for this reason that continuing professional development (CPD) and performance assessment are essential in our profession. We must be aware of the risks of clinical practice when making daily decisions and use our clinical judgment in tandem with published evidence-based guidelines/protocols/practices. In my clinical experience, working mindfully, effective communication (written, verbal, visual) with the multidisciplinary team (MDT) and patients, reflection, evaluation and critical appreciation of our work are essential to achieve this, for example, MDT meetings, have contact details of relevant personnel and documentation of situations and actions taken middle of paper ......anatomy?, human error?, correct plan?), handling and processing images and clinical decision-making using local verification guidelines. Relevant experience and reflection on decision-making (e.g. defining objectives for achieving the required level of competence, recording all clinical skills and associated reflections on practice) are essential in relation to verification and imaging on the processing unit. In conclusion, in my opinion, safe and optimal. care regarding daily decisions requires technical expertise, the ability to think critically, experience and clinical judgment. High expectations of RTs depend on daily adaptation, CPD, prioritization of workload, professional responsibility, independent and interdependent decision-making and creative problem solving within the unit treatment, as illustrated by the examples above from my clinical practice..
