Purpose: Radiation safety and protection are a key component of fluoroscopy-guided interventions. We hypothesize that providing weekly personal dose feedback will increase radiation awareness and ultimately will lead to optimized behavior. Therefore, we designed and implemented a personalized feedback of procedure and personal doses for medical staff involved in fluoroscopy-guided interventions.
Materials And Methods: Medical staff (physicians and technicians, n = 27) involved in fluoroscopy-guided interventions were equipped with electronic personal dose meters (PDMs). Procedure dose data including the dose area product and effective doses from PDMs were prospectively monitored for each consecutive procedure over an 8-month period (n = 1082). A personalized feedback form was designed displaying for each staff individually the personal dose per procedure, as well as relative and cumulative doses. This study consisted of two phases: (1) 1-5th months: Staff did not receive feedback (n = 701) and (2) 6-8th months: Staff received weekly individual dose feedback (n = 381). An anonymous evaluation was performed on the feedback and occupational dose.
Results: Personalized feedback was scored valuable by 76% of the staff and increased radiation dose awareness for 71%. 57 and 52% reported an increased feeling of occupational safety and changing their behavior because of personalized feedback, respectively. For technicians, the normalized dose was significantly lower in the feedback phase compared to the prefeedback phase: [median (IQR) normalized dose (phase 1) 0.12 (0.04-0.50) µSv/Gy cm versus (phase 2) 0.08 (0.02-0.24) µSv/Gy cm, p = 0.002].
Conclusion: Personalized dose feedback increases radiation awareness and safety and can be provided to staff involved in fluoroscopy-guided interventions.

Teaching high quality paediatric basic life support to laypeople: The development and evaluation of a virtual simulation game.

Background: Self-directed training has been recognized as a reasonable alternative to traditional instructor-led formats to teach laypeople Basic Life Support (BLS). Virtual tools can facilitate high-quality self-directed resuscitation education; however, their role in teaching paediatric BLS remains unclear due to limited empiric evaluation and suboptimal design of existing tools.
Aim: We describe the development and evaluation of a virtual simulation game (VSG) designed to teach high-quality paediatric BLS using a self-directed, online format with integrated deliberate practice and feedback.
Randomised, placebo-controlled, double-blinded, four-way crossover trial to demonstrate the comparative pharmacodynamic equivalence of a non-invasive diagnostic test for adrenal insufficiency in a healthy population: the STARLIT-2 study protocol.

Introduction: Cortisol is an essential stress hormone and failure of its production, known as adrenal insufficiency (AI), is associated with significant mortality due to adrenal crisis. The Short Synacthen Test (SST) is the current diagnostic test of choice for AI, but it is both invasive and resource intensive. Globally, there is an unmet need for a non-invasive, cost-effective test.

Background: The recent global pandemic posed extraordinary challenges for healthcare systems. Frontline healthcare workers required focused, immediate, practical, evidence-based instruction on optimal patient care modalities as knowledge evolved around disease management.
Objective: This course was designed to provide knowledge to protect healthcare workers; combat disease spread; and improve patient outcomes.

Health service policies are evolving into qualified health care providing best possible outcomes as well as focused on patient satisfaction. Hence the qualification valued health care includes patient satisfaction measurements, it is suggested to get feedbacks during the assessment of outcomes from the patient's perspective. Aging of the world population accelerates demand on rehabilitation medicine which means recovering impairments so is directly related with quality of life.

Background: Greater therapeutic alliance has been associated with an improved treatment outcome in various clinical populations. However, there is a lack of evidence for this association in posttraumatic stress disorder (PTSD) in young patients. We therefore investigated the development of the therapeutic alliance during Developmentally adapted cognitive processing therapy (D-CPT) in adolescents and young adults with PTSD following abuse to answer the question whether there was a connection between the therapeutic alliance and symptom reduction.
