UNASSIGNED: Previous studies sought to identify survival or outcome predictors in @entity1 with @entity1030 and @entity1576 , but their findings are inconsistent. We identified mortality-associated factors in a prospective study in 21 centers in 7 countries. Follow-up data were available in 221 @entity1 on home mechanical ventilation and/or long-term @entity26 therapy. MEASUREMENTS: diagnosis, co-morbidities, medication, @entity26 therapy, mechanical ventilation, pulmonary function, arterial blood gases, exercise performance were recorded. Health status was assessed using the @entity1030 -specific SGRQ and the @entity1576 -specific MRF26 questionnaires. Date and cause of @entity204 were recorded in those who died. Overall mortality was 19.5%. The commonest causes of @entity204 were related to the underlying @entity1576 . At baseline, @entity1 who subsequently died were older than survivors (p = 0.03), had a lower forced vital capacity (p = 0.03), a higher use of @entity26 at rest (p = 0.003) and a worse health status (SGRQ and MRF26, both p = 0.02). Longitudinal analyses over a follow-up period of 3 years showed higher median survival times in @entity1 with use of @entity26 at rest less than 1.75 l/min and with a better health status. In contrast, an increase from baseline levels of 1 liter in O2 flow at rest, 1 unit in SGRQ or MRF26, or 1 year increase in age resulted in an increase of mortality of 68%, 2.4%, 1.3%, and 6%, respectively. In conclusion, the need for @entity26 at rest, and health status assessment seems to be the strongest predictors of mortality in @entity1030 @entity1 with @entity1576 .
