    Abstract:
    BACKGROUND AND OBJECTIVE: The prevalence of difficult or prolonged weaning from mechanical ventilation is increasing because of a growing number of elderly patients with multiple diseases and pulmonary problems requiring mechanical ventilation. Intensive care units (ICU) are inclined to refer to specialized unit those patients who are difficult to wean. A nationwide survey of German facilities was conducted and this article reports the current state of weaning centers staffed by chest physicians. PATIENTS AND METHODS: 38 centers participated in the survey, which was divided into 10 items, covering characteristics of the hospital, weaning strategies, patients and outcomes during 2006. The survey included 2718 patients in whom weaning was difficult or prolonged. Almost three quarters of patients were transferred to one of the weaning centers from the ICU of another hospital. RESULTS: The weaning success rate was 66.4%. In 31,9 % of patients home mechanical ventilation was started after they had been weaned. The overall hospital mortality rate was 20.8%. There were major differences between individual centres concerning the number of patients, organization of the weaning unit and weaning strategies. CONCLUSIONS: Weaning was successful in two thirds of patients who had been on prolonged mechanical ventilation and had then been transferred to weaning facilities staffed by chest physicians. These centres effectively improved the quality of care of patients on prolonged mechanical ventilation by avoiding long-term invasive ventilation and sparing cost-intensive ICU resources. The problems that still exist may be overcome by a network of weaning facilities.
