Over 50 years I have studied and worked in health care, over 40 years as a medical specialist anesthesiologist-intensivist-pain therapist. I have worked globally. The last 20 years I spent working on Mediprepare. Recently I have decided to make the software open source. The goal is that doctors can create their own questionnaires and easily run them online, worldwide, in all languages, and share the good questionnaires with colleagues. To the benefit of all patients.
