Magsårssjukdomens paradigmskiften – Från högspecialiserad vårdorganisation till egenvård

Knowledge development and paradigm shift for peptic ulcer disease is described over a fifty-year period using four levels of knowledge that place demands on the healthcare organization. When medical knowledge reached a healing level, continuity became subordinate. However, accessibility to treatment became more important. An important task for future healthcare will be to define and create broader knowledge structures. Efficiency losses can occur when control instruments apply to medical problems at low levels of knowledge which are not mature for this.
