AbstractThe prevalence of difficult or prolonged weaning from the ventilator is increasing due to a growing number of multi-morbid, elderly and pulmonary deficient patients being mechanically ventilated. Intensive care units (ICU) tend to refer difficult to wean patients to specialised weaning facilities. A survey of 38 centres - performed in 2006 - included a total number of 2718 patients with difficult or prolonged weaning. Almost three quarters of the patients were transferred to a weaning centre from an external ICU. The weaning success rate was 66.3 %. After weaning in 31.9 % of the patients, home mechanical ventilation was started. The overall hospital mortality rate was 20.8 %. Recently the task force "WeanNet" - a network of weaning units - was founded under the auspices of the German Thoracic Society. The main aim of WeanNet is to improve cooperation among the weaning centres and the quality of patient management. Important tools of WeanNet are (i) the register of weaning patients and (ii) accreditation of the weaning centres. To develop the register an intensive cooperation between the task force and the Institute for Lung Research (ILF) was necessary. The finished register is now logistically run by ILF. In less than 1 year after the official start, already 70 weaning units with ca. 3000 patients are registered. In future "WeanNet", in particular in terms of the register and the accreditation, will stand for the quality of weaning centres in Germany.Copyright Georg Thieme Verlag KG Stuttgart . New York.
