Abstract
A prospective multicenter study was carried out from October 1 to November 30, 1991, to determine the incidence, severity, and mortality of acute respiratory failure (ARF) in Berlin, Germany, a metropolis with a population of 3.44 million. Adult patients from 72 intensive care units (ICUs) were evaluated. ARF was defined as: (1) intubation and mechanical ventilation (I + MV) ⩾ 24 h; (2) age ⩾ 14 yr. Incidence of ARF was assessed as the number of patients fulfilling ARF criteria within the 2-mo study period. Severity of ARF was defined as “no lung injury” (NLI), “mild-to-moderate lung injury” (MMLI), and “severe lung injury” (SLI) according to Murray and coworkers' proposals. Mortality was assessed as number of patients with ARF dying during ICU stay. During the study period, 508 patients were diagnosed as having ARF, representing an incidence of ARF of 88.6 per 100,000/yr. Twenty-four h after I + MV, MMLI occurred in 94% and SLI in 3.6% of the ARF patients. Overall mortality rate was 42.7%. Mortality rate in the NLI group was 36.4%; in patients with MMLI, 40.8%; and in patients with SLI, 58.8%. Our data offer novel information on incidence, severity, and mortality of ARF in a major urban population.
