Arranging medical education giving you a headache? Our doctors prescribe Oslr ! Working with clinicians across the UK, we’ve built Oslr to make arranging hospital training easy. CONNECT - Match sessions to students’ needs TEACH - Find times that work for everyone LEARN - Add and share peer recommended resources IMPROVE - Capture teaching and feedback for your portfolio Doctors / Trainers We know the best doctors and trainers incorporate teaching and continuous improvement into their practice, but you're busy and don't always have time to plan lessons, find appropriate patients, resources or students and chase them for feedback. Built by doctors, Oslr simplifies workplace teaching and learning. With just a few clicks you can connect with peers, share resources, post teaching sessions to meet student needs and automatically log training with feedback for CPD. Students To become a great doctor you need workplace training to interface with doctors, real patients and all health care professionals, but they are busy. Developed with medical students, Oslr enables you to request teaching across specialties, access peer recommended resources, join live teaching sessions to learn how to engage, pick-up signs, make diagnosis and provide feedback in confidence, whilst all your learning is automatically captured to help you graduate with flying colours. Oslr is a new way for doctors, medical students and health care professionals to coordinate workplace teaching in hospitals. Learning to examine real patients is a core part of every doctor's training, but can be difficult to coordinate around busy schedules and unpredictable patients. Oslr solves this problem. Institutions You know workplace training has never been more essential to deliver the best care, but how do you ensure the training, often informal and undocumented, is optimal at busy institutions? Developed with hospitals and medical schools, Oslr not only increases the amount of training delivered, it precisely captures what is being taught, where, who's attending and feedback. Enabling promotion of best practice, identification of training gaps, resource optimisation and a comprehensive record of workplace medical training. *** This app is designed for doctors and medical students based in UK hospitals. A valid university or NHS email address is required to unlock full functionality. *** This application can also be accessed by https://www.oslr.co.uk/ Great doctors teach - Oslr makes it easy !
