Dr. Meissner undertook his residency as an anesthesiologist at University Hospital Berlin-Steglitz, after which he was appointed head of Jena University Hospital’s pain unit in 1994, and head of the palliative care department in 2009. The pain unit covers all areas of pain management (including an acute pain service, outpatient service unit, inpatient consultation service, multimodal pain management program and interdisciplinary pain conference). Dr. Meissner and his group have initiated and coordinated two large registries in the area of acute pain: quality improvement in post-operative pain management (QUIPS) in Germany and its international counterpart, improvement in postoperative pain outcome (PAIN OUT). These registries offer feedback and benchmarking of pain treatment outcomes and facilitate health service research. The registries comprise more than 500,000 data, resulting in more than 50 publications so far. In addition, he was the coordinator of the NeuroPAIN project (chronic pain and neurologic consequences in sepsis survivors) and has broad teaching experience, including the development of curricula for perioperative care, palliative care, and medical communication. He is the coordinator of EC-funded IMIPainCare's subproject, Patient reported outcome measures to improve management of acute and chronic pain (PROMPT), which involves setting up a registry to follow-up postsurgical pain. Meissner is president-elect of the German Pain Society and a member of several national and international societies including the European Society of Anaesthesiology (ESA) and the International Association for the Study of Pain (IASP).
